Abstract All of the pollutants found in stormwater runoff at airports, including surface and aircraft de-icing/anti-icing glycols, can be treated and removed to low levels in well-designed sub-surface flow (SSF) constructed wetland systems. There are two common forms of constructed wetlands used for pollution control: those where water flows over the surface among wetland plants (free water surface or marsh type wetlands); and SSF types where the wastewater flows below the normally dry surface of a gravel substrate in which the wetland plants grow. SSF wetlands have no open water to attract waterfowl and are particularly suitable for use at airports. Of the glycol used at Edmonton International Airport (EIA), 80 to 90% eventually entered surface runoff. Edmonton International Airport's operator, the Edmonton Regional Airports Authority (Edmonton Airports) evaluated a number of glycol management options, including constructed wetlands. As a result, a very large SSF wetland system was installed to handle glycol-contaminated stormwater. This paper reviews results of a feasibility study carried out to define design parameters and scale up kinetics for this wetland system, the detailed design that resulted, the SSF wetland's construction, and the start-up of the Edmonton facilities in August of 2000. It also compares the Edmonton wetland system with a similar facility at Heathrow Airport in the United Kingdom.

Background: Finding the best location for the airport reduces the negative effects of construction and its activity on the environment. This study aimed to evaluate the establishment of the airports (Mehrabad and Imam Khomeini airports) in Tehran province through integration of multi-criteria decision making (MCDM) methods and noise pollution modeling software. Methods: The criteria for zoning the airports were determined using Delphi method, and then, were weighed using analytic network process (ANP). One of the criteria was noise pollution. The computer aided noise abatement (CadnaA) software was used to map the noise level at the airports. The geographic information system (GIS) software and weighted overlay method were used to zone Tehran province for construction of the airports. The percentage of voice annoyance was defined according to the questionnaire provided by the International Commission on the Biological Effects of Noise (ICBEN). Results: Prioritization between the selected criteria using ANP and TOPSIS showed that the most important criteria are the land use (0.069) and the distance from the city (0.0598), respectively. The highest percentage of highly annoyed (%HA) persons was reported at both airports at Lden levels above 70 dB. Conclusion: According to the results of this study, the location of Mehrabad and Imam Khomeini airports is considered 60% and 18% inappropriate, respectively. The results introduce a set of criteria that determines compatibility rate of different activities around the airports based on the noise levels. Finally, it is recommended to study the correlation between aircraft noise pollution indicators in other airports of Iran and design a local model for the whole country.

Full textAbstract:
The article highlights the experience of design and construction with the expansion of existing airports, considers the factors that shape the development trends of modern international airports. Some general principles and methods of expansion of international airports are revealed. The formation of modern airports is influenced by many factors, primarily socio-economic and trends in air transport. In the last 20, 30 years, the largest percentage of the world's reconstruction is with the mandatory expansion of airports. Thus, the main issues of development of modern airports are the principles and methods of their expansion. Additional factors influencing the reconstruction of modern airports are issues of terrorist and virological security. If the issue of terrorist threats has influenced functional decisions for several decades, the virological threat is quite new and requires a comprehensive study and implementation of new measures of various kinds. Also, the purpose of the reconstruction of modern airports is to improve the level of comfort and safety, which are the main factors in the marketing struggle for air passengers and air cargo. The publication considers several typical modern examples of airport reconstruction, both in Europe and in the post-Soviet space - Kutaisi (Georgia), Marseille (France), Oslo (Norway), Amsterdam (Netherlands). The publication highlights that the expansion of the airport requires some mandatory stages. Namely, determining the appropriateness of the expansion and the main functional tasks for which this expansion should take place, determining the principles and techniques by which the expansion of the terminal will be most rational, determine whether the increase in passenger traffic requires runway expansion, determine how the increase in passenger traffic additional functions (parking, trade and food services, etc.).
Of the above examples of expansion of modern airports, the most accurate is the method of expansion, which is a kind of symbiosis of building a new terminal with redistribution of functions between the new and old terminal, and with the simultaneous addition of necessary planning transitions and galleries.

Purpose Metroplex is a system of two or more airports, in physical proximity, with highly interdependent arrival and departure operations. The purpose of this study is the construction of an efficient and effective air route model based on the point merge system (PMS) to reduce aircraft fuel consumption and CO2 emissions for three metroplex airports in Istanbul terminal control area (TMA). Design/methodology/approach A PMS arrival route model is constructed for metroplex airports. In the proposed model, two situations are taken into consideration: for delay which can be defined as flying on sequencing legs (PMSdel) and for no delay (PMSno del). An empirical model is developed using a data set including the flight data records of ten actual B737-800 domestic flights. With this empirical model, both the baseline and the PMS models (PMSdel and PMSno del) are compared in terms of fuel consumption, CO2 emissions and flight distance and time as a theoretical computation. Findings In the proposed PMSno del arrival route model, according to different entry points for Istanbul Ataturk International Airport (LTBA), the analyses show an average reduction of 26 per cent in flight time, 24.5 per cent in flight distance, 17 per cent in fuel burned and CO2 emissions; in addition, for Sabiha Gökcen International Airport (LTFJ) there are 34, 23 and 32 per cent average savings for flight time, flight distance and fuel burned together with CO2 emissions obtained, respectively. Even if the PMSdel model, for LTFJ except only one entry point, for LTBA except two entry points, better results are obtained than baseline. Practical implications The point merge model for metroplex airports in this paper can be applied by airspace designers and Air Navigation Service Providers to perform efficient and effective arrival routes. Originality/value In this study, a point merge model is constructed for metroplex airports. Quantitative results, using an empirical model, are achieved in terms of fuel consumption, CO2 emissions and flight distance and time at metroplex airports.

Full textAbstract:
The Federal Aviation Administration (FAA) has taken measures to improve safety, reduce costs, increase resilience, and improve the sustainability of the United States (U.S.) airfield infrastructure by using a life-cycle cost analysis methodology to increase the efficient use of economic resources needed for expanding and preserving the airfield system. However, a life-cycle assessment (LCA) approach for evaluating the environmental impacts of decisions regarding airfield infrastructure has yet to be fully developed and applied. The objective of this study is to demonstrate the use of the airfield LCA framework that was developed for the FAA and can be used by U.S. airports. The comparison of alternative pavement designs at Nashville International Airport (BNA) is presented. The scope of the study was from cradle to laid; materials, materials transportation, and construction stages of the pavement life cycle are considered, and the maintenance, use and end of life stages are not considered. Primary data were acquired from BNA and secondary data were used in situations of unavailability of primary data. The case study showed that performing LCA provides opportunities for airports to consider energy use and environment-related impacts in the decision-making process.

According to the ventilation and heat issues of Beijing Capital International Airport T3 Terminal Station Transportation Center (GTC), based on the actual conditions of the building structure, geographical location, climate and other characteristics, the internal environment of temperature and other issues are analyzed and researched. And the relationship of indoor air flow and interior space of the building is established. With methods of CFD, and from the perspective of the Energy Saving and Environmental Protection, natural wind and related technology are utilizes, and natural ventilation and heat transferring guidance systems are designed, so that the internal temperature is reduced and the indoor comfort is improved. Introduction Beijing Capital International Airport is located on a piece of land of Chaoyang District on the northeast of Beijing, 25.35 km from Tiananmen Square. It is the busiest transportation and production major international airports of China, on the most important location, with the largest and most complete equipment. Beijing Capital International Airport T3 Terminal Station Transportation Center (GTC) is located to the south of the T3 Terminal Building, with total construction area of more than 34,000 square meters. 1,2-floors underground are open-large parking garage, the first floor has multi-hub facilities supporting the airport, and the second floor is suburban railway stations. The roof is a glass dome, and used long-span structures. The main functional area is a large space, and the external structure for large area is glass walls. The form is determined by functional requirements of the terminal station and visual and psychological demands of people. More precisely, the form not only is a concrete manifestation of humanized design, but also brings the problem of high energy consumption.

Full textAbstract:
Sustainability and the concept of sustainable development now forms part of governmental policy around the world. The United Arab Emirates is no different, recognising that its ecological footprint and continued growth require management of resources and waste streams. A fundamental part of this is sustainable construction and operation of civil engineering projects such as buildings, roads and airports. Geotechnical engineering is required on practically all civil engineering projects yet is often overlooked when design and construction decisions are being made regarding civil engineering sustainability. One of the most common ways to measure sustainability in civil engineering projects is through rating tools. Rating tools have grown and developed internationally for decades and are used across the world for various different projects (buildings, roads, infrastructure etc.). The United Arab Emirates have developed their own local ratings tools (and sustainability frameworks) and have mandated their use in certain projects. There is significant scope for geotechnical engineering to contribute to improving sustainability and rating tools are one element that can be developed. A detailed review of local and international ratings tools is carried out to understand where geotechnical engineering can currently contribute and the possibilities to improve geotechnical sustainability in the United Arab Emirates are discussed.

Full textAbstract:
The Haneda Sky Arch, located in front of the new passenger terminal of Tokyo International Airport (Haneda Airport), consists of a pair of steel-cable-stayed girder superstructures supported by a main arch pylon. In the construction of the new terminal, two design concepts were given priority, recognizability and architectural harmony. To help achieve such a goal, this unique arch bridge was designed to become the symbol for the newly enlarged airport. The three-dimensional arrangement of the cables lends an elegant grace to the Sky Arch when viewed from various vantage points, and its unique structural form makes it readily identifiable. The Sky Arch integrates numerous interesting features, including (a) slender main girder superstructures that suggest the lines of an airplane's wing, (b) interesting stainless steel details, (c) smooth cold-worked curves on arch rib corners, and (d) field-welded splices to minimize the use of mechanical fasteners. These features are in complete harmony with the architecture of the other facilities. Fulfilling both functional and decorative purposes, the remarkable design of the Haneda Sky Arch enhances the overall attractiveness of the new airport facilities.

The new Athens International Airport "Eleftherios Venizelos" (AIA) has been constructed in theheart of the Mesogaia plain, approximately 25 kilometres northeast of Athens. The airport, whichhas been constructed on agricultural land that was once used for the cultivation of vegetables,fruits, olives, and other fresh products, commenced operations in March 2001.The Environmental Department (ENC) of AIA was established from the first day of the company'soperation in summer 1996. The responsibilities of ENC are related to the EnvironmentalManagement System, aircraft noise, air quality, resources monitoring, water management, naturalenvironment, waste management, cultural heritage, and community projects. AIA is the first Hellenicairport, with an Environmental Department that has been certified according to EN ISO 14001since December 2000.The airport and the activities directly and/or indirectly associated with its operations can have anenvironmental impact on water. In order to avoid such impacts, ENC closely monitors and takes initiativesregarding several water issues including: Ground water, Surface water & Potable waterMonitoring.The purpose of this paper is to provide detailed information regarding water management issues,especially those related to monitoring programs. Several such programs are conducted on aregular basis (some having commenced even prior to airport operations, e.g., groundwater and surfacewater) where the different water media are sampled, sent to accredited laboratories, analysedfor a selected suite of parameters, and checked for environmental compliance. If any of the waterstested are in non-compliance then a series of corrective measures are initiatedGroundwater sampling and analysis have been conducted on the airport site prior to airportopening. Results indicate that the parameters observed in exceedance to European legislation areattributed to agricultural practices that were prevalent prior to the airport construction rather thanfrom airport operationsSurface water sampling has been conducted on the site since airport opening. The selectedsuite of parameters tested from specific locations show that no systematic elevated levels havebeen recorded. The initiatives of ENC, including training, environmental auditing of Airport's ThirdParties, and remediation measures, have contributed to this outcomeThe results from the potable water sampling and analysis, which is conducted in cooperationwith EYDAP, indicate that water quality is in compliance with Greek legislation.This paper will be of interest to researchers, practitioners, and policy-makers, since it providesuseful information regarding the design, implementation, and outcome of water monitoring programs.

The environmental impacts of airport pavement construction were evaluated in this study through a life-cycle analysis approach. Total primary energy (TPE) consumption and greenhouse gas (GHG) emissions from material production and construction of pavement were determined by using life-cycle assessment (LCA), a quantitative methodology described in the ISO 14040 series. A tool was developed to implement a probabilistic LCA through the Monte Carlo method. This tool allowed for consideration of uncertainty from life-cycle inventory data. A case study on the construction of Runway 10R-28L at Chicago O'Hare International Airport focused on mainline and shoulder pavement designs. Environmental impacts from producing materials for the pavements increased from lower to upper layers, while asphalt layers had relatively higher TPE consumption than the upper portland cement concrete layer—and vice versa for GHGs. Impacts from material production overshadowed those from construction, which contributed less than 2% of TPE consumption and GHGs. Further analysis showed that two production processes—for asphalt binder and portland cement—were the leading contributors (45.3% and 29.2%, respectively) of TPE consumption, while the latter was the leading contributor (73.4%) of GHGs. A probabilistic analysis compared the original 10R-28L runway design and a modified design that did not use recycled materials or warm-mix asphalt technology. The results from 1,000 Monte Carlo simulations showed that the environmental impacts from the two cases were statistically significant, with the original design having lower TPE consumption (482 versus 693 MJ/yd2 for TPE) and GHGs (37.5 versus 53.9 kg of carbon dioxide equivalent per square yard).

Airport agencies spend millions of dollars to remove ice and snow from airport pavement surfaces to achieve accessible, safe, and sustainable operations during the winter. Electrically conductive concrete (ECON) based heated pavement system (HPS) has gained attention as a promising alternative technology for preventing snow and ice accumulation by maintaining pavement surface temperatures above the freezing point. The objective of this study was to demonstrate the world’s first full-scale ECON-based HPS at a U.S. airport. Two ECON slabs were designed and constructed in the General Aviation (GA) apron at the Des Moines International Airport (DSM), Iowa in 2016. Systematic design components were identified, and construction procedures were developed and implemented for ECON-based HPS. Using collected sensor data, the performance of the constructed and remotely-operated ECON slabs was evaluated under real weather conditions at DSM in the 2016–2017 winter season. The results demonstrate that ECON-based HPS have promising deicing and anti-icing capacities, promising to provide uniform heat distribution and prevent snow and ice accumulations on the entire area of application under various winter weather conditions, including extreme cold weather (i.e., arctic blasts).

Purpose Research carried out within the scope of the present new emerging optimum market to Greek regional airlines. This study (based on interconnected flight network) aims to provide an optimal alternative for flights to be carried out by small Greek airlines to Eskisehir Airport in Turkey. The airlines seek to sustainable demand base to improve themselves in a profitable way. Design/methodology/approach In this study, the analytical network process method was used. In the construction of network models, specific criteria have been considered, and the analysis has been accomplished as multi-criteria decision-making problem because of the relationship and interaction between them. A number of professionals with high knowledge of the Greek and Turkish aviation market were participated in the study. Findings Both Greek and Turkish experts think that the scenarios should include more airports (multi leg flights) to benefit from the increased traffic from all these destinations. Although, the model showed that more sustainable and effective routes are the simplest ones (single leg flights). Thus, the experts suggested the following five routes: Athens (ATH)-Antalya (AYT)-Eskisehir (AOE)-ATH; Heraklion (HER)-AOE-ATH; ATH-Istanbul (IST)-AOE-Thessaloniki (SKG); ATH-AOE-Cologne (CGN)-ATH and ATH-AOE-Izmir (ADB)-CGN-ATH. In addition, the experts pointed out the routes Eskisehir (AOE)-Brussel (BRU) and AOE-Cologne (CGN), as the passenger demand for them is high. These are considerable suggestions and should be examined by airlines’ managers, while aviation authorities should take these under consideration. Research limitations/implications There are some factors that limit the potential extension of the small Greek regional airlines to Eskisehir airport. Istanbul’s Atatürk International Airport is the most used airport for international connected flight in Turkey, and the most airlines prefer this as a destination airport, although it has slots limitations and intense traffic. According to a previous project, sustainable flight network may include Istanbul and Izmir. Also, the bilateral agreement between Greece and Turkey according to Memorandum of Understanding between the Aeronautical Authorities of the Republic of Turkey and Hellenic Republic consists the main limitation of the traffic increase. Practical implications Connected flight network model suggestions developed in this research may provide contribution to airlines’ research and development activities. Also this kind of studies may contribute to the increase of the passengers’ traffic between the two countries with mutual benefits. Social implications Based on the current study, with determined the grid network flights, new flights can be scheduled that are offering significant benefits. Also passengers will have the ability to travel to an attractive destination. In particular, the study may positively contribute to the further development of AOE and to the region around the city. On the other side, the Greek regional airlines can find an important market. Anadolu University’s entrepreneurship ability will be improved and also AOE’s business will be increased. This study will enforce the stronger links between both Greek [Hellenic (Greek) Civil Aviation Authority] and Turkish (General Directorate of Civil Aviation) aviation authorities. In addition, this study may contribute to the improvement of the economic relations between Greece and Turkey with mutual benefits. Originality/value It is thought that this research shows Greek and Turkish airports feasibility to cooperate providing benefits to passengers, airlines and the countries’ economies. The study includes current social, economic and cultural dynamics of the countries making significant contribution to academic literature. The capacity and demand analysis is useful for the management of the specific Greek carriers. Expert opinions are consulted over the course of taking strategic decisions. The analysis has been conducted, based on expert opinions and referred to for these pairwise comparisons. Airlines and airport managers based on the suggested methodology may examine potential flights, although more numerical data are necessary.

Abstract Recently urban waterlogging problems have become more and more serious, and the construction of an airport runway makes the impervious area of the airport high, which leads to the deterioration of the water environment and frequent waterlogging disasters. It is of great significance to design and construct the sponge airport with low impact development (LID) facilities. In this paper, we take catchment N1 of Beijing Daxing International Airport as a case study. The LID facilities are designed and the runoff process of a heavy rainfall in catchment N1 is simulated before and after the implementation of LID facilities. The results show that the total amount of surface runoff, the number of overflow junctions and full-flow conduits of the rainwater drainage system in catchment N1 of Beijing Daxing International Airport are significantly reduced after the implementation of the LID facilities. Therefore, the application of LID facilities has greatly improved the ability of the airport to remove rainwater and effectively alleviated the risk of waterlogging in the airport flight area. This study provides theoretical support for airport designers and managers to solve flood control and rainwater drainage problems and has vital practical significance.

The Central Artery/Third Harbor Tunnel Project in Boston, Massachusetts, is one of the largest highway projects over undertaken in the country. It requires the replacement of the existing elevated artery, I-93, with an underground tunnel extending through downtown Boston and an extension of the Massachusetts Turnpike Authority (MTA) I-90 from its existing termination at the I-93 interchange to Boston's Logan International Airport. The I-90 extension tunnels east under the existing South Station intercity and commuter railroad tracks, under historic Fort Point Channel while crossing above the 1915 twin subway tunnels, and continues through industrial South Boston with ramps surfacing in a new South Boston interchange, the heart of tremendous growth in Boston. From there the tunnel connects to the recently completed Ted Williams Tunnel harbor crossing to East Boston and Logan International Airport. The unique design challenges and solutions relating to the Fort Point Channel crossing, particularly the use of in-the-wet construction with concrete immersed-tube tunnels and the design interface to the ventilation structures, are presented. Structures required for the I-90 extension are concrete immersed tubes and jacked tunnels, as well as more conventional cut-and-cover tunnels, bridges, surface roads, and ancillary buildings. The geometric and physical restraints of the alignment initially required the placement of the ventilation building, which serves the tunnels, on a cut-and-cover tunnel transition section between the jacked tunnels and the concrete immersed tubes. Ultimately, placement of the ventilation building on the immersed tubes created a substantial cost and schedule benefit.

Full textAbstract:
Purpose The purpose of this paper is to conduct life-cycle cost analysis of a short-haul underground freight transportation (UFT) system for the Dallas Fort Worth international airport. Design/methodology/approach The research approach includes: identifying the cost components of the proposed airport UFT system; estimating life-cycle cost (LCC) of system components using various methods; determining life-cycle cash flows; evaluating the reliability of the results using sensitivity analysis; and assessing the validity of the results using analogues cases. Findings Although the capital cost of constructing an airport UFT system seems to be the largest cost of such innovative projects, annual costs for running the system are more significant, taking a life-cycle perspective. System administrative cost, tunnel operation and maintenance, and tunnel construction cost are the principle cost components of the UFT system representing approximately 46, 24 and 19 percent of the total LCC, respectively. The shipping cost is estimated to be $4.14 per ton-mile. Although this cost is more than the cost of transporting cargos by trucks, the implementation of UFT systems could be financially justified considering their numerous benefits. Originality/value This paper, for the first time, helps capital planners understand the LCC of an airport UFT system with no or limited past experience, and to consider such innovative solutions to address airport congestion issues.

This article surveys the official narrative on representation of Estonian identity and Estonianness through the tourism strategy implemented by Estonia from 2007 to 2015. Gathering material from brochures and documents targeting foreigners produced by the Estonian Institute and “Enterprise Estonia” (EAS) and analyzing the logic behind the interior design of Tallinn Airport, we engage with current debates on identity construction in post-Soviet spaces. In particular, we suggest that along with an established body of literature looking at the role of state actors in the construction of identity, studies should consider the role of nontraditional or non-state actors in identifying and promoting identity markers.

Full textAbstract:
Purpose This work presents the part of the research in the integration of the remotely piloted aircraft systems (RPAS) in non-segregated airspace. The purpose of this study is to elaborate the reference shape of the Standard Instrument Arrivals (STARs) procedures of controlled airports. The STARs parameters are unique for the aerodromes and depend on navigational aids (NAVAIDs), manoeuvres and aircraft categories. Therefore, the elaboration of reference shapes was advisable in the context of RPAS integration research. Design/methodology/approach The models were based on the procedure design guidelines by International Civil Aviation Organization. The statistics of existing STARs were prepared using Aeronautical Information Publications to determine the representative procedural parameters. Construction of procedural shapes required to define the nominal flight path and tolerance areas. Findings In statistics, the standard deviation of distances was below the determined reference mean values, thus the models were convergent with existing procedures. Research limitations/implications The modelling was limited to initial, intermediate, final and missed approach segments. Arrival segment was not modelled. NAVAIDs include Instrument Landing System Category 1 (in final and missed approach) and very high-frequency omni-directional ranging or global navigation satellite systems (in initial and intermediate approach segments). Practical implications Prepared models may be used in research in the integration of the new types of aerial vehicles in existing air traffic management systems. Originality/value The reference STARs possess commonly used procedural manoeuvres (straight-in, turn, racetrack and base turn) and different NAVAIDs. The parameters of approach segments were determined as representative of the existing procedures. Moreover, the models are suitable to place at arbitrary origin and runway axis bearing.

A review of current international aviation noise requirements is provided. It is shown that international requirements for aircraft noise levels are constantly increasing. The rapid growth of the international fleet leads to an increase in the number of take-offs and landings of aircraft at airports, and as a result, the problem of aircraft noise still relevant. To reduce noise levels at airports, various methods are used, one of which is the operational limitations of aircraft concerning the levels of noise they create. In European Union countries there are operational restrictions for aircraft meeting the requirements of Chapter 3 with a noise margin of less than 10 EPNdB. For already established aircraft that have passed certification, again it is necessary to look for methods to reduce noise. The main type of aircraft in operation in the world is an aircraft with turbofan engines. For such an aircraft, the main sources of noise during take-off will be the noise of the fan and jet, while landing, the noise of the landing gear, flaps, slats, and fan noise. When choosing a method of reducing aircraft noise, it should determine the source that most affects the overall noise level. It has been determined that fan noise is one of the main sources of noise. Acoustic liners constructions are widely used to reduce the noise level created by the fan. They are one of the most priority areas for reducing fan noise. Achievements in the use of acoustic liners to decrease the noise of domestic aircraft An-124-100, An-148-100 are considered. It is noted that due to the increasing requirements for aircraft noise, it is necessary to use new acoustic liners with improved sound-absorbing properties. It was determined that it is possible to improve the sound-absorbing properties of the acoustic liners by expanding the frequency range of sound absorption of such structures.Modern methods for improving the acoustic properties of the acoustic liners are presented: the use of multilayer resonant acoustic liners makes it possible to customize the design for an increased number of calculation parameters; the use of modified variants of the acoustic liners core such as corrugated core, oversized perforated core; the use of porous and porous fiber materials in the design of the acoustic liners to provide additional sound-absorbing ability, the use of low-frequency acoustic liners to reduce the noise of promising turbofan engines with a high and ultra-high bypass ratio.

Purpose: Aviation sector in Kenya facilitates both international and domestic trade, promotes tourism and foreign investment thus contributing to government revenue and employment opportunities. Therefore, improving airport infrastructure would help reduce travel time, improve connectivity. The high rates of project failure have become a major concern for stakeholders hence the need to identify key factors that promote project success or failure. This study seeks to assess the critical success factor influencing the performance of construction projects in Kenya.Methodology: The study adopted quantitative method to examine critical success factors for the performance of aviation construction projects in Kenya. Descriptive case study research design was adopted and self –administered questionnaires were used to collect quantitative for analysis. The variables of interest include timely financing project activities, competency of contractors, participation of stakeholders, and management skills. Descriptive analysis and inferential tests were conducted with the aid of IBM SPSS version 23 software.Results: The study found that timely financing, contractor competency, stakeholder participation, and management skills have positive and significant influence on the performance of aviation construction projects. Descriptive results suggest that tractors competency, timely financing, management skills, and stakeholders’ participation have a strong positive influence on project performance. The study has also established a significant contribution of contractor competency to the successful performance of aviation construction projects. It was also noted that participation of key stakeholders in projects identification, decision making, and resource mobilization can enhance the success of aviation construction projects. It was observed that these factors account for over 54.9% of changes in project performance.Unique contribution to theory, policy and practice: In light of these results, the study recommends industry players to put measures in place that would allow timely provisions of finance for all project activities. It is also important to source for competent and experienced contractors, engage key stakeholders in decision making about the project, and recruit a competent and skilled project manager. The study results have a significant contribution to practitioners in the aviation construction sector in Kenya. The study provides the practitioner with the most critical variables likely to influence the performance of aviation construction projects. It further acknowledges that external factors also influence the success of these projects. In light of this, the practitioners can institute contingency plans to mitigate the risks to ensure successful completion of their projects. To the academic, the current study has filled literature gap on critical success factors for aviation project performance. Given the upcoming mega project in aviation sector around the world, these factors provide the basis for future research in this area to ensure these projects are executed successfully within budget and schedule

Aimed to solve the problem that the mass concrete structures are apt to crack in underground engineering, this paper makes some research from the view of crack resistance performance of polypropylene fiber concretes. Since polypropylene fiber achieves waterproof through realizing of crack resistant, blending polypropylene fibers into concretes can reduce early contraction deformation of concretes, hinder emergence of plastic shrinkage cracking and improve impermeability of concretes, and its construction technology is simple. In practical application of this in anti-cracking and anti- seepage concrete structures in the International Terminal project of Hangzhou Xiaoshan International Airport, we find that mix of polypropylene fibers with concretes clearly improves anti-cracking and anti-seepage performance of concrete structures and meets design requirements of basements through measuring temperature and observing cracking condition of the mass concrete structures of basements on site. The project can provide experience for reference to similar projects.

Full textAbstract:
Damage to underground water pipes can be traced back to the 1923 Kanto earthquake, and it was well recognized from the early days that seismic effect was important in the construction of underground structures. It was not known, however, how seismic effect could be included in the design and construction of underground structures. In the late 1960s, field measurements and shaking table experiments gradually showed that ground deformation developed during an earthquake induced deformation in underground structures. This finding led to the development of new seismic design for underground structures embedded in subsurface ground. This was first designated as the “seismic deformation method” when the “new seismic design method” was developed as the final accomplishment in a five-year research project by the Ministry of Construction in 1977. In the 1960s and 1970s, Dr. Okubo took the leadership in developing seismic design methods for underground tunnels, pipelines, and bridges. Transportation of aviation petroleum was a critical requirement for the new Narita International Airport. Because no alternatives for transporting aviation petroleum other than pipeline embedded under national roads were possible in congested urban areas, it was important to protect pipelines and roads against seismic effects. When the law for petroleum pipelines went into effect, a seismic design method for petroleum pipelines was included in the notice on technical detailing on petroleum pipelines in 1973. This was the first mandated requirement for underground structures in seismic effects. Subsequently, seismic design based on the seismic deformation method has been extensively used for underground structures. Dr. Toshio Iwasaki, head of the Ground Vibration Division of the Public Works Research Institute of the Ministry of Construction at that time named this method the “seismic deformation method.” The author, a researcher of the Ground Vibration Division at the time, proposed calling it the “deformation method.” Because “deformation method” was widely used in computational structural analysis, Dr. Iwasaki suggested adding “seismic” to “deformation method.” As shown in his paper, Dr. Okubo contributed greatly to clarifying the failure mechanism of seismic damage, and compiled technical knowledge on seismic effect in various design codes. His interest extended beyond underground structures to bridges, roads, and dams. He expanded the foundation of seismic design of civil infrastructures in the early days of earthquake engineering.

INTRODUCTION: The construction industry depends mainly on labour to translate other resources into a physical object (i.e. building, road, airport etc.). The industry’s workforce is always mobile and its activities are characterized by difficult working conditions. The mobile workforce of industry and their vulnerability to HIV/AIDS pandemic have been fairly researched. The objective of the study is to determine construction workers’ HIV/AIDS knowledge, risk sexual behaviours and their attitude towards HIV/AIDS.METHOD: The study adopted a cross sectional research design and purposive sampling method was used to select respondents. The researched area included sites in Dar es Salaam, Morogoro and Dodoma cities. A sample size involved 20 construction sites and 5 respondents from each site. A hundred questionnaires were distributed out of which 58 were fairly filled.The study adapted standard questionnaires developed by UNAIDS, Family Health International (FHI) and Demographic and Health Surveys (DHS). The collected data was analyzed using the Statistical Package for Social Sciences (SPSS) software version 20.0.RESULTS: The results show that most construction workers have low HIV knowledge, low risk sexual behaviours and positive attitude towards HIV/AIDS. Furthermore, indicators of low knowledge were evident in awareness of PMTCT services, HIV can be spread through breastfeeding, HIV can be spread through sharing injection and HIV can be spread through unsafe sex.CONCLUSION: In conclusion risk sexual behaviours are low, attitude towards HIV/AIDS is generally positive but HIV knowledge is low. However, there are alarming concerns in some indicators of both risk sexual behaviours and attitude noted in the study.

Purpose Although South Asia is a growing supplier of migrant labour, there is a paucity of research on the health and well-being of male Nepalese migrant workers. The purpose of this paper is to assess the health and mental well-being of Nepalese construction and factory workers employed in Malaysia, Qatar and Saudi Arabia. Design/methodology/approach A structured questionnaire administered, in and around Nepal’s international airport, to 403 migrants who had worked for over six months in their host countries. Logistic regression was used to investigate factors associated with self-reported health status and mental health symptoms. Findings Over 13 per cent reported poor or very poor health and nearly a quarter reported mental health issues. Whilst age and exercise were significantly associated with health status, poor work environments and perceived health risks were associated with both mental health issues and health status. Research limitations/implications The study is limited to males only and those working in the factories and the construction industry. To improve migrant health and mental well-being, Nepalese and host governments should consider mandatory health insurance and a range of pre-departure and arrival education around general literacy, mental health assessments and workplace health and safety. Originality/value There have been no known studies on the health and well-being of Nepalese migrant construction and factory workers in the Middle East and Malaysia. The strong association between self-reported poor health and perceived work environment is an important issue that policy makers in Nepal and destination countries should address.

AbstractThe article considers the legal implications of a proposal by the Netherlands Government to build a new airport on an artificial island in the sea. The article concludes that the construction and use of an artificial island remains in principle within a coastal state's authority, with due regard to the rights and duties of other states and the LOS Convention and other rules of international law. Account must be taken of conflicting uses of the sea, for example, navigation, fishing, offshore activities, submarine cables and pipelines, and overflight. Freedom of overflight will be dealt with by the ICAO. With regard to other aspects of air law, such as liability and aviation security, there are no clear indicators of the appropriate course to take. The uniqueness of an airport at sea requires the Netherlands to tread new ground, requiring it to devise new ways for removing possible obstacles.

The main purpose of the reconstruction of this airport is to ensure that the engineering infrastructure complies with the modern requirements of air transportation services and transport security. In our opinion, the list of objects of reconstruction, which now includes an apron, lighting equipment, two checkpoints, a system for lighting aircraft parking places, a water supply network, communications, heat, perimeter fencing, etc., must necessarily enter and passenger terminal. While it is not listed. The article deals with the problem of determining the reliability and future operational suitability of the base and foundations of the passenger terminal at the «Sokol Magadan Airport» with a service life of more than 50 years. In this regard, a brief description of the natural conditions of the territory of the specified object is given. The peculiarity of the construction area is its seismicity (up to 8 points), deep seasonal freezing and insular distribution of permafrost soils. The problem is due to the fact that this building, consisting of two independent blocks, each of which was erected in different years on different types of pile foundations, practically began to undergo deformations after their commissioning. These deformations are manifested and manifest now on the external and internal walls in the form of cracks of different sizes. An attempt to determine their causes was made during the construction of the second half of the building, but it coincided in time with the collapse of the USSR, and therefore was not brought to a logical end. The object was put into operation without correcting the existing errors in the foundation device and foundation structures, as well as the necessary strengthening measures in such cases. In the future, it was limited to periodic redecoration and decommissioning of the most dangerous premises for people to visit. The present paper assesses the very difficult natural conditions of the territory (climate, island degrading permafrost, seismic), where the «Sokol Airport» has been operating for more than half a century. During this time, many objects of its engineering infrastructure as a result of negative interaction with the environment have received noticeable physical and moral deterioration. These include the passenger terminal. In this regard, they almost all need modern modernization and reconstruction, especially since «Sokol Airport» has received international status of Federal significance. The article substantiates the need for a geotechnical survey of the base and foundations of a deformable building. The implementation of this work is due to the alleged reprofiling of the problem building under the cargo terminal. The results of the survey will be used in the design of a new passenger terminal.

Abstract The purpose of this study is to analyse how tourists’ perceptions of a destination’s tourism product influences memorable tourism experiences and how gender differences influence tourists’ perceptions of tourism product. To achieve these objectives, Uganda, one of the developing economies in East Africa, was chosen. The five A’s of tourism product was used as a basis for the questionnaire construction and data was analysed. Explanatory research design within the framework of confirmatory factor analysis - a structural equation modelling technique was adopted using the AMOS 18 program. A sample of 501 respondents consisting of tourists departing Uganda through Entebbe International Airport was used.Results showed that both the measurement and structural models exhibited better model fit indices. Overall, tourists’ perceptions of the retained four dimensions of tourism product (Attractions, ancillary services, amenities and accommodation) had a positive effect on memorable travel experience. Additionally, the independent T-test for gender and tourists’ perceptions of Uganda’s tourism product showed that on average, females had a positive evaluation of Uganda tourism product compared to their male counterparts. However, the observed difference was not significant.It is recommended that destination management organisations pay attention to infrastructure, particularly transport that links potential and actual tourists to key tourism attractions. This is likely to enhance positive perceptions and was found to positively influence memorable travel experience. Other implications for destination branding are discussed.

The construction of the new airport in Kulon Progo, Indonesia does not stop at the seizure of people's agricultural land. The seizure will expand due to displacement capital to obtain a new space for capital accumulation. With its various designs, space is conditioned in such a way as to maximixe the capital accumulation. As a displacement capital, YIA will connect the business sectors, especially tourism. In this article, I try to uncover the spatial expansion that occurs due to the construction of the new airport and how the space is defined as capital accumulation by using David Harvey and Henri Lefebvre. Through spatial analysis, this article explains how infrastructure development affects to the marginalization of the people through spatial projections made by the state and corporations. In addition, the imagery of spatial expansion also influences the expansion of labor transferred for the needs of capital accumulation.

Using minimum spanning tree technique (MST), this exploratory research was done to optimize the interrelation and hierarchical network design of Indonesian’s airports. This research also identifies the position of the Indonesian’s airports regionally based on the ASEAN Open Sky Policy 2015. The secondary data containing distance between airports (both in Indonesia and in ASEAN), flight frequency, and correlation of Gross Domestic Regional Product (GDRP) for each region in Indonesia are used as inputs to form MST networks. The result analysis is done by comparing the MST networks with the existing network in Indonesia. This research found that the existing airport network in Indonesia does not depict the optimal network connecting all airports with the shortest distance and maximizing the correlation of regional economic potential in the country. This research then suggests the optimal networks and identifies the airports and regions as hubs and spokes formed by the networks. Lastly, this research indicates that the Indonesian airports have no strategic position in the ASEAN Open Sky network, but they have an opportunity to get strategic positions if 33 airports in 33 regions in Indonesia are included in the network.

Smart societies will make more intelligent use of Information and Communication Technology (ICT), which has the potential to transform the way to plan and manage infrastructures. New developments in computer hardware, as well as new applications and software, are changing the face of the infrastructure sector and society more generally, driving greater efficiency, increasing productivity, and greatly simplifying construction processes and life-of-asset maintenance. In European countries, the adoption of Building Information Modeling (BIM) standards have been expedited. In this research article, the architectural-structural model in a BIM environment of the elevated walkway connecting the gate with the runway, a project named “IV Bridge” under construction for the expansion of the departure area of Naples Capodichino International Airport, is carried out. Software including Autodesk family, Revit for the architectural/structural model, Robot Structural Analysis (RSA) for the analytical verification and Naviswork (NW) for the 4D/5D model were used. The effectiveness and benefits obtained by implementing the BIM methodology are discussed, showing a reduction in terms of construction times and costs.

Full textAbstract:
With the conduction of west development in China, the constructions of airports in the southwest mountainous areas are being carried out rapidly. Due to the various exteriors limitations, the embankment engineering in airports often exist some problems such as large height and slope ratio. So the stability of high embankment engineering is very essential to the construction and operation of airport. The cost of geo-grid material is very low and the construction is convenient. The embedding and occlusion of soil mass can be realized through its unique grid structure. The practical engineering shows that the stability of high embankment engineering can be solved through laying geo-grid in the filling soil. At the same time, FEM strength reduction can take the interaction between the components of geo-grid and soil into full consideration. As a strict mechanic method, FEM strength reduction can be reasonably and reliably adopted in the stability analysis, design and calculation of reinforced body with geo-grid.

Full textAbstract:
To scientifically and accurately evaluate the status of the development of green airports in China, evaluation methods of green, ecological airports are established in this paper. To address the shortcomings in subjective and objective weighting methods, we propose a combination weighting method based on Spearman’s rank correlation coefficient and evaluation grades based on interval approximation. At the same time, by taking into account resource conservation, environmental friendliness, operation efficiency, and people-oriented service, we propose an evaluation index system and an interval number for each index. Lastly, the theory is applied to five large airports in different regions of China. Analysis of the evaluation results shows that Shanghai Pudong International Airport (PVG) and Guangzhou Baiyun International Airport (CAN) have the highest scores for the resource conservation and environmental friendliness indexes, thus indicating that the development of a green ecological airport is closely related to its passenger transportation scale and economic strength. All considered airports showed the need for upgrading public service facilities and constructing intelligent equipment. The method proposed in this paper is reasonable and reliable; therefore, it can provide guidance for the evaluation and construction of green, ecological airports.

Full textAbstract:
Reclaimed airports usually have fragile geological structures and are susceptible to the uneven ground settlements caused by filling-material consolidation, underground construction, and dynamic loading from takeoff and landing of aircrafts. Therefore, deformation monitoring is of great significance to the safe operation of reclaimed airports. This study adopts an improved permanent-scatterer interferometric synthetic-aperture radar strategy to map the spatiotemporal deformation of Shenzhen Bao'an International Airport in China using ascending and descending Envisat/ASAR data acquired from 2007 to 2010 and Sentinel-1 data from 2015 to 2019. The results show that uneven settlements of the airport concentrate in the new reclaimed land. Then we explore the settlement characteristics of each functional area. Furthermore, we separate out the dynamic-load settlement of runway No. 2 and confirm the settlements caused by dynamic load. This study provides new ideas for studying deformation in similar fields, and technical references for the future construction of Shenzhen Airport.

"Jointed Plain Concrete Pavements in Airports: Structural–Economic Evaluation and Proposal for a Catalogue."

Full textAbstract:
Although the design of jointed plain concrete pavements could be solved by commercial software, there is still a need for simple tools to be used in feasibility studies and preliminary cost–benefit analyses. This paper analyzed and verified jointed plain concrete pavements for airports composed of square slabs without tie and dowel bars. The examined slabs are laid on a cement-treated base layer and a stabilized granular subbase layer. The finite element software FAARFIELD was used to design the JPCP pavements when they are subjected to the design of the airplane (i.e., turboprop C-130J Hercules) under different conditions. Seven subgrade load bearing capacity values, twenty traffic levels, and two construction hypotheses (i.e., constant or variable thickness of the two deeper layers) were designed and then verified with the Westergaard theory in order to present a proposal for a catalogue. Finally, the construction cost per unit surface area was calculated for different construction methods of paving (by slip form paver or by fixed form). The obtained results provide a simple and fast procedure to design preliminary airport JPCPs.

Communicable diseases including COVID-19 pose a major threat to public health worldwide. To curb the spread of communicable diseases effectively, timely surveillance and prediction of the risk of pandemics are essential. The aim of this study is to analyze free and publicly available data to construct useful travel data records for network statistics other than common descriptive statistics. This study describes analytical findings of time-series plots and spatial-temporal maps to illustrate or visualize pandemic connectedness. We analyzed data retrieved from the web-based Collaborative Arrangement for the Prevention and Management of Public Health Events in Civil Aviation dashboard, which contains up-to-date and comprehensive meta-information on civil flights from 193 national governments in accordance with the airport, country, city, latitude, and the longitude of flight origin and the destination. We used the database to visualize pandemic connectedness through the workflow of travel data collection, network construction, data aggregation, travel statistics calculation, and visualization with time-series plots and spatial-temporal maps. We observed similar patterns in the time-series plots of worldwide daily flights from January to early-March of 2019 and 2020. A sharp reduction in the number of daily flights recorded in mid-March 2020 was likely related to large-scale air travel restrictions owing to the COVID-19 pandemic. The levels of connectedness between places are strong indicators of the risk of a pandemic. Since the initial reports of COVID-19 cases worldwide, a high network density and reciprocity in early-March 2020 served as early signals of the COVID-19 pandemic and were associated with the rapid increase in COVID-19 cases in mid-March 2020. The spatial-temporal map of connectedness in Europe on March 13, 2020, shows the highest level of connectedness among European countries, which reflected severe outbreaks of COVID-19 in late March and early April of 2020. As a quality control measure, we used the aggregated numbers of international flights from April to October 2020 to compare the number of international flights officially reported by the International Civil Aviation Organization with the data collected from the Collaborative Arrangement for the Prevention and Management of Public Health Events in Civil Aviation dashboard, and we observed high consistency between the 2 data sets. The flexible design of the database provides users access to network connectedness at different periods, places, and spatial levels through various network statistics calculation methods in accordance with their needs. The analysis can facilitate early recognition of the risk of a current communicable disease pandemic and newly emerging communicable diseases in the future.

Full textAbstract:
In this paper are investigated actions for public health protection in airports’ tourism facilities and actions that promote innovation at Airports’ sustainable construction infrastructures to minimize associated pollution threats. An integrated framework is presented based on a comprehensive and analysis of the community airport tourism centers and sustainable design facilities in sustainable construction infrastructures in transportation related to waste management facilities and energy recovery from landfill emissions that are produced at nearby places at airports. Research in Sustainable Airport Designs and Infrastructures is necessary to solve common operating problems, to adapt appropriate useful information technologies, and to introduce innovations into the airport tourism industry. The study reveals sustainability dimensions that are lagging or require much greater attention, such as sustainable designs, environmental management, monitoring, safety and public health protection of tourists at airport facilities. In this study are presented useful solutions for sustainable airport designs that promote sustainability supporting an Integrated Sustainable Tourism Policy for Public Health Protection and Sustainable Development within associated infrastructures and airport facilities. Useful conclusions are made for the airport tourism industry, sustainable infrastructures, environmental technologies, renewable resources, sanitary facilities and associative infrastructures developing innovative near-term solutions to meet demands placed on it.

Full textAbstract:
This paper proposes a new airport typology that might arise from the expansion of airports with dominant low cost carrier traffic. In the first part of the paper, the typologies and different airport categorizations are reviewed with examples of current taxonomies used by principal international organizations. However, none of the current airport taxonomies takes into account low cost (LCC) carriers and cannot be used to create an airport market strategy with LCC operation. The paper highlights the characteristic of LCC features, the differences between the LCC airlines, and the characteristics of secondary – low cost airports. Finally, the paper proposes a new taxonomy of airports with low cost operations based on the airport data analysis and expert panel elucidation. For identification of airports with a high share of low cost carriers, Eurocontrol 2013 data on airline types and movements were used. The novel classification of low cost airports enables management to design marketing strategies to respond to LCC dominance and its implications. The main contribution of this research is to provide a novel classification for low cost airports which is relatively new phenomenon comparing with the problems of full service carriers dominance at large airports.
