Abstract:
The transportation network construction takes place over a quite long time span and need enough budget. The budget is from the allocation of funds in phases and the construction cost change in the process of the construction. The general static transportation network design problems ignores the problems above. So the optimal solution obtained by the static model is best in short time, and it is may be unfeasible in the actual situation. Based on the actual situation and the shortage of the static model, the time-dependent transport network design is proposed in this study. The plan horizon is divided into N intervals and a bi-level model is built to describe the problem. The objective of the upper-level is to minimize the total cost of the whole stages. the lower-level model is a user equilibrium model. Then the branch and bound (B-B) algorithm is designed to solve the model. It is obvious that the solution of the time-dependent simulation model is more feasible than the solution of the static sequential design.

Abstract:
A traditional discrete network design problem (DNDP) always assumes transportation infrastructure projects to be one-time events and ignores travelers’ delays caused by construction work. In fact, infrastructure construction usually lasts for a long time, and the impact on traffic can be substantial. In this paper, we introduce time dimension into the traditional DNDP to explicitly consider the impact of road construction and adopt an overtime policy to add flexibility to construction duration. We address the problem of selecting road-widening projects in an urban network, determining the optimal link capacity, and designing the schedule of the selected projects simultaneously. A time-dependent DNDP (T-DNDP) model is developed with the objective of minimizing total weighted net user cost during the entire planning horizon. An active-set algorithm is applied to solve the model. A simple example network is first utilized to demonstrate the necessity of considering the construction process in T-DNDP and to illustrate the trade-off between the construction impact and the benefit realized through capacity extension. We also solve the T-DNDP model with data from the Sioux Falls network, which contains 24 nodes, 76 links, and 528 origin-destination (O-D) pairs. Computational results for the problem are also presented.

Abstract:
The development of a new initiative for the Kentucky Transportation Cabinet to involve resident engineers and contractors in the project development process, especially for environmentally sensitive projects, is summarized. To meet the demands of human and natural environmental issues on transportation projects, many departments of transportation are embracing the tenets of context-sensitive design for their projects. Some have begun to expand this involvement to all participants in the project development process and are calling this initiative "context-sensitive solutions." The Kentucky Transportation Cabinet believes that it is critical to involve its resident engineers and contractors in the process to ensure success on environmentally sensitive projects. In the planning and design stages of project development, the commitments that are made are not always carried into the construction stage and implemented. Context-sensitive construction is the integration of the concepts of context-sensitive design into the construction process and adherence to all commitments made during the earlier stages of project development. The Kentucky Transportation Center and the Civil Engineering Department at the University of Kentucky developed a training program to introduce the concepts of context-sensitive solutions for the construction phase of a project to industry and cabinet personnel, and that program is described.

Abstract:
The article presents how three scaled down industrial machinery models were designed and built as an educational tool to present the transport of particulate material. The literature review showed calculation models for equipment at industrial level, not for laboratory level. There were chosen the most representative means of commercial transport for particulate materials: a conveyor screw, a conveyor belt and a bucket elevator. These three machines were calculated and built in polycarbonate to allow visualization of their internal functioning. The three devices are controlled by a programmable logic controller (PLC) and connected to each other by a SCADA network. The equipment is modular so as not to alter the order of operation, being able to obtain different work sequences. In addition, a man-machine graphic interface (HMI) was developed to supervise and to control the designed equipment. The results of particulate material mass flow obtained are approximately coincident with those estimated, validating the use of calculation models for much lower levels of work. Finally, it is emphasized that the system obtained is an environment for students to implement control techniques using the sensors and motors used in the designs.

Abstract:
Purpose In build-operate-transfer (BOT) transportation projects, design and construction phases are critical in terms of their effect on time and cost overruns. The purpose of this paper is to identify the role of risk factors affecting these phases and their significance level for BOT transportation projects. Design/methodology/approach Design and construction risks were determined and then validated by focus group discussions. Afterwards, an illustrated case study was presented to better understand the effects of determined risks in a BOT mega transportation project. As the last step of the study, the fuzzy analytical hierarchy process method was used to prioritize risk factors. Findings The prominent risk factors were found out as occupational accidents, integration between design and construction phases and excessive design variations. Research limitations/implications Different kinds of BOT transportation projects in different countries might be executed very differently considering specific social, political, economic and other factors. However, the results of the study are important in terms of the specific lessons learned from the case study that can be used as a foundation for developing possible risk mitigation measures. Originality/value Though the risk management of BOT projects has been investigated frequently in the literature, there is a knowledge gap in the quantitative evaluation of risk significance specific to design and construction risks. The prioritization of determined risks with an associated case from a mega transportation project will contribute to the BOT project practitioners about possible challenges in design and construction phases in BOT mega transportation projects.

Abstract:
A huge amount of construction waste is generated in construction sites every day that needs to be transported by vehicle to disposal facilities for processing. Unlike in most typical transportation problems, once these vehicles are loaded with construction waste, they must travel directly to the disposal facility. Moreover, there are different types of construction waste that may require handling by different disposal facilities. In this paper, we develop a model and algorithm for identifying the optimal transportation routes specific to construction waste transportation. Our results can not only minimize the overall costs for both the logistics company and the contractor but also minimize the distance traveled, thus reducing urban traffic emissions.

Abstract:
As a growing and increasingly mobile population demands the construction of new transportation facilities, often in environmentally sensitive areas, the significance of quality transportation aesthetics cannot be overemphasized. Given the associated costs, impact, and permanence of these facilities, it is imperative that citizen advisory groups, public agencies, and design professionals work together in striving to improve the design and construction of transportation facilities. The Glenwood Canyon Tunnel in western Colorado is testimonial to the successful corroboration of these groups. Designed by Parsons Brinckerhoff and completed in 1993, the Glenwood Canyon Tunnel transports Interstate 70 traffic through one of the most scenic areas in the United States while preserving its natural features, vistas, and associated recreational opportunities. Architectural aesthetics and environmental concerns were driving forces in the design of the tunnel, in addition to life safety, tunnel ventilation, and surveillance. This study elaborates on the emphasis given to aesthetics and environmental concerns in the design of the tunnel, the Shoshone and amphitheater portals, and the Cinnamon Creek ventilation and control complex, as well as on the coordinated efforts of all those involved in making the Glenwood Canyon Tunnel state of the art and an aesthetically pleasing reality that has gained recognition throughout the United States.

Construction is among the leading industries/activities contributing the largest carbon footprint. This review paper aims to promote awareness of the sources of carbon footprint in the construction industry, from design to operation and management during manufacturing, transportation, construction, operations, maintenance and management, and end-of-life deconstruction phases. In addition, it summarizes the latest studies on carbon footprint reduction strategies in different phases of construction by the use of alternative additives in building materials, improvements in design, recycling construction waste, promoting the utility of alternative water resources, and increasing efficiencies of water technologies and other building systems. It was reported that the application of alternative additives/materials or techniques/systems can reduce up to 90% of CO2 emissions at different stages in the construction and building operations. Therefore, this review can be beneficial at the stage of conceptualization, design, and construction to assist clients and stakeholders in selecting materials and systems; consequently, it promotes consciousness of the environmental impacts of fabrication, transportation, and operation.

Abstract:
Sugarcane juice is a perishable food with a good nutritional profile. Thus, there is a need to increase its shelf life by reducing water content which facilitates storage and transportation. In this study, process conditions were optimized to concentrate the sugarcane juice at various microwave powers (30, 50, 80, 100 W). A central composite design was applied to optimize the process conditions (power and time). The overall evaporation time depends on microwave powers; increase in power reduced the processing time. The results showed that at 100 W sugarcane juice was concentrated to 75° brix for 15 min which reduced the energy consumption to 1.3 times compared to other powers. Moreover, microwave processing better retained the sensory properties of concentrate and preserved its antioxidant activity. Thus, 100 W was most energy efficient in concentrating sugarcane juice. In general, microwave processing reduced the processing time and cost making it a sustainable approach to concentrate juices.

Abstract:
In view of the lack of unified data architecture and model of workshop transportation system components, this paper proposes the concept of the workshop transportation system functional unit based on asset administration shell (AAS). The designed workshop transportation system can solve the problem of unified modelling for different types of equipment, and realize the rapid construction and adjustment of the system. Meanwhile, the system has been applied in the specific workshop transportation system and enables well application results. In the functional unit of workshop transportation system, automatic markup language (AML) is applied. This paper constructs the AAS model based on the industrial 4.0 reference architecture model (RAMI4.0), and introduces the workshop transportation system AAS model and its realistic mapping as an example. The workshop transportation system functional unit AAS model based on the RAMI4.0 provides an effective solution for the standardization and integration of workshop transportation system components, which is no requirement to develop specific data conversion tools for this purpose. All transportation equipment with AAS can achieve information exchange and interoperability. It is conducive for the rapid implementation of workshop transportation system engineering and provides a guide for the establishment of intelligent workshop. Thereby, the proposed methodology demonstrates the flexibility and interoperability of AAS in smart manufacturing.

Abstract:
<p>With the continuous development of cities, the urban roads built in the early days can no longer meet the needs of modern urban transportation. Therefore, in the current urban development and construction process, the reconstruction of old roads is the key construction content. At the same time, the transformation of old urban roads is also an inevitable requirement to improve the urban road system and improve the level of urban communication infrastructure construction and transportation service capacity. The reconstruction of old roads meets the requirements of the overall planning and construction of modern cities, and plays a vital role in promoting the development and progress of urban economy and improving the quality of life of urban residents. In the process of urban old road reconstruction, because the original urban road environment is very complex and involves many factors, the rational design of the construction scheme of the old road reconstruction project is the key factor affecting the effect of the old road reconstruction. This paper makes an in-depth exploration and analysis of the old road reconstruction design of urban roads, and puts forward scientific and reasonable suggestions in combination with the actual situation, so as to provide reliable theoretical support for improving the old road reconstruction level and promoting the urbanization development process in China.</p>

Abstract:
Road construction on major freeways is a primary cause of traffic incidents and delays. One approach to improve traffic mobility and safety in construction work zones is to use intelligent transportation systems (ITSs), which can effectively enhance work zone traffic management through advanced surveillance and communication technologies. Although conceptually similar to a traditional advanced traffic management system, a work zone ITS has unique network and communication design requirements. The Palm Beach County, Florida, Interim Traffic Management System (ITMS) was a work zone ITS that was successfully deployed in the summer of 2003. Using Palm Beach County ITMS as an example, this paper provides technical guidelines for applying cutting-edge technologies, such as wireless communication, video compression, and Internet protocol encapsulation, in designing a work zone ITS.

Abstract:
Bulk materials are necessary for hydropower construction. The bulk materials transportation (BMT) scheme is a guiding document for material supply, and its selection has a significant influence on hydropower construction. Since the BMT problem includes transportation planning and scheme selection issues simultaneously, only a small number of studies have focused on it. This paper presents a theoretical two-stage decision-making method (TDM), which innovatively combines the path optimization method and the multi-criteria decision-making (MCDM) method to solve the BMT problem. In the first stage, a multi-source path optimization model is established to optimize the transportation network and obtain a set of alternatives from each supply point to the construction site. In the second stage, considering the factors of economy, risk and construction progress, the MCDM method is adopted to select the optimal scheme from the alternatives. In addition, web crawler technology is used to obtain the transportation network data from the public WebGIS automatically. Case results show that the TDM can effectively solve this problem, and its result keeps consistent with engineering practice; with the help of the web crawler, it can reduce the design task time from months to days. Therefore, the TDM based on WebGIS can benefit hydropower construction design efficiency.

Abstract:
Purpose The purpose of this paper is to present a taxonomy of transportation waste in construction production processes based on lean construction (LC) principles. Design/methodology/approach The research methodology used is case study and the main stages for the identification of the transportation waste in two construction projects were: mapping physical flows; measurement of transportation time; and monitoring of transportation waste events; assessment of the taxonomy. Findings The main contribution of this paper is the proposition of a taxonomy of transportation waste in construction production processes through the understanding of the transportation waste causes and consequences. Research limitations/implications Although the literature reviewed addresses sources from different parts of the world, the case studies performed are limited to one country, Brazil. However, the studies were carried out in two different construction sites separated by more than 3,000 km. Practical implications All data collected during the taxonomy application can be organized in order to develop an improvement plan. Moreover, if data collected is disseminated, there is the potential to increase the efficiency and effectiveness of the construction sector. Social implications Although the paper does not explore in depth the impact of the study on society or policy, the theme of waste minimization is focused on cost reduction, and one way to do that is through the flow management for waste minimization. Originality/value The paper discusses the concept of transportation waste of production in construction based on LC philosophy, through the understanding of its causes and consequences.

Abstract:
A mixed transportation network design problem considering sustainable development was studied in this paper. Based on the discretization of continuous link-grade decision variables, a bilevel programming model was proposed to describe the problem, in which sustainability factors, including vehicle exhaust emissions, land-use scale, link load, and financial budget, are considered. The objective of the model is to minimize the total amount of resources exploited under the premise of meeting all the construction goals. A heuristic algorithm, which combined the simulated annealing and path-based gradient projection algorithm, was developed to solve the model. The numerical example shows that the transportation network optimized with the method above not only significantly alleviates the congestion on the link, but also reduces vehicle exhaust emissions within the network by up to 41.56%.

Abstract:
Purpose Building information modeling (BIM) is a process of generating and managing building data during the building’s life cycle. To increase productivity in building design and construction, BIM uses three-dimensional (3D) real-time, dynamic building modeling software. Because of its versatile features, BIM use is on the rise and researchers are exploring its application in new disciplines. The purpose of this study is to map out how BIM is used in the construction industry, while identifying and highlighting the research gaps in the literature. Design/methodology/approach To investigate the status quo of knowledge about BIM, the authors conducted a comprehensive literature review. They applied and extended a methodology for reviewing BIM-related publications through a four-dimensional meta-analysis system and its categories, which has been partially adapted previously. Findings Majority of studies applying BIM for the construction phase of civil engineering projects were done within universities; none used BIM for the construction of intermediate railway stations. Practical implications To increase the construction efficiency of intermediate railway stations, applying the BIM concept for generation and management of station data should be considered for future research. Originality/value Furthermore, one of the main goals of this research paper is to explore the adoption of BIM in civil engineering construction projects, in particular the construction of intermediate railway stations.

Abstract:
It’s a compressive article consists of three parts, an overview of pipeline development in China, oil pipeline design for R oilfield and pipeline management suggestions. First, this article introduces the current status of pipeline construction, oil pipeline technology and gas pipeline technology in China in recent years. The current status of China’s pipeline construction is divided into three stages. In terms of construction, pipeline construction is developing in the direction of intelligence and modernization. Long-distance oil pipelines require technical breakthroughs in two aspects. One is the sequential oil product delivery technology to improve the type of oil that can be delivered sequentially; the second is the viscosity reduction delivery technology for heavy oil. Gas transmission pipelines are developing in the direction of high pressure, large diameter and high steel grade. Secondly, based on all the pipeline development above, in order to meet the development of R oil field, an oil-water two-phase pipeline transportation design and a pipeline crossing river design were carried out. Under the condition of the design pressure of the pipeline of 5.5MPa, it is preferable to produce a pipeline of φ219×6.5mm, and the steel grade of the pipeline is L360. A heating station and pumping station are needed in the transportation process, and the heating station and pumping station are combined for one construction. Considering that the strata of the river crossing section are mainly gravel sand layer, clay layer and non-lithological stratum, horizontal directional drilling (HDD) is adopted for river crossing, and suggestions are made for the construction process. Finally, after the pipeline was put into production, the corresponding auxiliary production system and supporting engineering suggestions were put forward.

Abstract:
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.

Abstract:
This study examined the challenges and their effects on sugarcane farming in the Malava sub-county, Kakamega County. The study objectives were to: assess cane transportation problems and establish challenges related to the marketing of sugarcane farmers in the Malava Sub-county. It was undertaken in Malava Sub-county, where sugarcane is the economic backbone and the region’s key cash crop owing to the favourable geographical conditions in Western Kenya. Despite Malava Sub-county’s vast experience in sugarcane farming, production has gone down. Furthermore, such a study is yet to be done in Malava. The study purposed to find out the reasons for inefficiency and insufficiency in sugar production. A descriptive research design was used. Purposive and systematic random sampling techniques were used to select sugarcane farmers from the seven wards; Manda/Shivanga, Butali/Chegulo, Chemuche, East Kabras, West Kabras, and South Kabras, Shirugu/Mugai and the sugar factory stakeholders in the two sugar factories; Butali and Kabras in Malava Sub-county. Malava Sub-county has an estimated population of 65,323 sugarcane farmers. From this population, a sample of 384 was used, based on Mugenda and Mugenda’s formula (2003): n=z2pq/d2, for a target population which is greater than 10,000. Primary data was collected by the use of questionnaires, interview schedules, Focus Group Discussions, and observation guides. Secondary data was collected through a literature search in online journals, theses and publications related to the study topic. Analysis was done using descriptive statistics aided by Statistical Package for Social Sciences (SPSS). The presentation of data was done using tables and graphs. A pilot study in Lwandeti and Chevaywa wards in Lugari Subcounty was conducted to test the validity and reliability of the data collection instruments, and Cronbach’s alpha of 0.8 was good evidence of reliability. Research findings showed that 70% (269) of the respondents accepted that the transportation charges were high compared to other costs of production, 60% (230) of the cane farmers sampled said that there was a ready market for mature sugarcane, while 40% (154) responded negatively and 100% of the farmers indicated that they never witnessed the weighing of their cane. Finally, 79.95% (307) of the farmers accepted that the equipment for the operation of cane farming was mainly the locally available ones for instance, Jembes, Pangas, and ox ploughs; and 83% (319) of farmers failed to uproot old cane due to lack of money to hire the tractors and high technology equipment. Small-scale farmers in the Malava sub-county have low productivity due to these factors. This study recommends that sugar millers cover transportation costs, provide licenses on schedule, introduce mobile weighbridges to allow farmers to observe the weighing of their cane, and the government provide loans for small-scale farmers to acquire village tractors
