Full textAbstract:
Over the past decades, information technology has been impacting industries, economics, the way of life and even the culture throughout the world. Productivity has been attracting much attention as an important indicator of economics, and numerous researchers have investigated the relationship between information technology and productivity. Construction is one of the largest industries in the United States, but little research has been conducted to investigate the relationship between information technology and construction productivity.
The major objective of this dissertation is to determine the degree (if any) to which information technology usage, specifically the use of information technology to automate and integrate construction project work functions, is related to construction productivity. First, the author analyzed the relationship between information technology and construction productivity on a national-level basis. Second, the author compared the relationship between information technology’ contribution to value added growth and productivity in the construction industry with other industries. Third, the author performed a series of statistical analyses to investigate the relationship between construction productivity and automation and integration applications at the construction project level. Based on the above results, the author developed a matrix to map the relationship between technology usage on each work function and productivity in the concrete, structural steel, electrical and piping trades. In addition, a technology index developed from technology usage on all of the work functions were used to investigate the general effect of information technology usage on a project level.
In order to leverage the relative importance of technology on each work function, regression analyses were performed to obtain a further understanding of the relationship. Factor analysis was also applied to identify the latent factors and simplify the patterns of relationships among the different work functions. This analysis could provide construction companies an indication about information technology usage priority and deployment in their work. Finally, a detailed examination of how Building Information Modeling, representing a current significant advancement of information technology usage on many construction projects, impacts the performance of a specific construction project is performed through a case example.

Full textAbstract:
This dissertation was the result of an investigation into the relative importance of construction as a curriculum organizer for the field of technology education. In particular, it concentrated on the relationship between construction technology and the principles of general education and technological literacy. The review of literature focused on the historic roles and meanings of this curriculum organizer and these principles as the discipline evolved from the industrial arts into technology education. Operational definitions were synthesized and the linkages between them was clearly identified.
To address technology education's contribution to general education, or the full development of the human personality, the spheres of human/technology interaction model was developed. The model is based on the idea that people interact with technology and evaluate those interactions from three fundamental perspectives. Those perspectives were identified as the civic-life sphere, the personal-life sphere, and the work-life sphere.
One hundred and forty-eight faculty members of technology teacher education programs in colleges and universities throughout the United States were surveyed. A 77% return rate was obtained. The survey included four major sections in addition to requesting limited information about the respondents and their programs. The four major sections asked the respondents to: 1) Evaluate potential goals for a K-12 technology education program. 2) Determine the relative importance of 10 study areas or curriculum organizers as they related to each of the three spheres of interaction. 3) Determine the percentage of the technology education curriculum that should be allocated to each of the three spheres of human/technology interaction. 4) Provide selected information about the way construction is offered and taught in technology teacher education programs.
Medoid cluster analysis was used to evaluate the data derived from the goals of technology education portion of the survey. Using this information, three clusters were formed and initial respondent membership for each cluster was established. Subsequently, discriminant analysis was used to accomplish three goals: 1) Refine the initial assignment of respondents to the clusters. 2) Identify those variables that offered a significant level of discrimination between clusters. 3) Determine the accuracy of assignment to the clusters or groups. The canonical correlation 2, calculated by the discriminant analysis program, indicated that 66.3% of the variance was explained by the variables that were significant at a .05 level. After comparing the mean scores of the discriminating variables across the three clusters, one cluster was identified as favoring technological literacy, one favored industrial technology education, and one was ambivalent.
T-tests were used to determine if any significant difference existed between clusters or groups. It was of particular interest to this research that no significant difference was found related to the relative importance of construction. All groups concluded that construction should comprise approximately 10% of the technology education curriculum.
Finally, a schedule was established which allocated various percentages of the curriculum to each of the 10 study areas or curriculum organizers as they relate to the three spheres of human/technology interaction. This schedule was based on the relative importance assigned by the technological literacy cluster. The technological literacy cluster offered the most balanced allocation of the technology education curriculum across the three spheres of human/technology interaction.<br>Ph. D.

Full textAbstract:
An intervention to improve adoption of dust control technology is designed, implemented and evaluated using three theoretical frameworks: the Health Belief Model (HBM), Diffusion of Innovation, and the Technology Acceptance Model. A quasi-experimental design (pretest-posttest, with control group) was used to evaluate the effectiveness of the intervention. An integrated conceptual model, employing key constructs from these frameworks, was developed to predict and describe â adoption readinessâ . Adoption readiness combines the attitudes and perceptions about a technology with the capacity to implement the technology. The primary hypothesis was that the key construct scores of the three theoretical models would improve post-intervention, particularly, â adoption readinessâ . Workers in the drywall finishing industry have been found to be at risk of developing respiratory disease and disability. Studies have shown that drywall finish workers have been subject to overexposure to dust concentrations that contain respiratory heath hazardous particles including silica, talc, mica, and calcite. Prevention through Design (PtD) solutions, which are effective at reducing dust levels, do exist for these operations. Some of these PtD solutions include using vacuum sanders, wet sanding methods, pole sanding and using low dust joint compound in lieu of using personal protective equipment (PPE) as a primary form of exposure protection. Previous studies have determined barriers to adoption of current PtD solutions for dust exposure reduction. Usability, productivity, quality of finish and cost were all identified as barriers to adoption. An intervention directed at those involved in the drywall industry is needed to increase the usage of engineered dust control.
This dissertation project developed, implemented, and evaluated three interventions to address the barriers to adoption through education and marketing strategies. Development of the interventions included strategies to improve industry usage of dust control technologies. The interventions targeted workers, small companies, and large companies involved in drywall finishing.<br>Ph. D.

Full textAbstract:
The last twenty years has seen a tremendous change in the way companies do business. Much of this change can be attributed to the so-called information revolution. The integrated interaction between Information Technology (IT) and business processes has changed from its initial function of automating clerical tasks (e.g. payroll, inventory) to providing pertinent information for operational, managerial and executive groups within the organisation. In more recent times, IT has enabled some organisations, including those in the construction industry, to transform or re-engineer their business processes in the face of the rapidly changing business environment. As international competition continues to intensify, significant numbers of construction organisations are investing large amounts of resources into IT as they seek to gain competitive advantage. IT is increasingly being implemented for strategic reasons, so as to enable improved efficiency, better control and enhanced productivity of internal processes. The failure of realising expected IT-induced benefits has led to a growing number of senior executives to question the value of IT investments. Thus, questions like the following are typical: Are we getting our money's worth from our IT investment? ; Are we spending too much or too little on IT? ; What IT projects make the best use of our resources? ; How can we improve the return on our IT investments? This Ph.D. research study was inspired by the perceived lack of a structured framework for the selection, implementation and performance evaluation of IT projects in construction. The development of such a generic framework that could capture the IT project lifecycle management process, and the associated guidelines and procedures for its effective implementation, is a young field of research, still struggling to define its place within the large family of academic disciplines. Being a young branch of science, it might be argued that IT in construction lacks a solid methodological foundation. An IT project lifecycle management process is an integrated approach that provides for the continuous identification, selection, implementation, monitoring and performance evaluation of IT projects. This structured process should provide a systematic method for construction organisations to minimise risks while maximising returns on IT investments. To effectively employ IT in construction, the IT project lifecycle management process should have elements of three essential phases: (1) IT project(s) selection; (2) strategic IT implementation and monitoring; and (3) IT performance evaluation. However, each phase should not be viewed as a separate step. Rather, each is conducted as part of a continuous, interdependent management effort. Information gained from one phase is used to support activities in each of the other two phases. With this in mind, this research study aimed to develop an appropriate framework and associated tools for each phase of the IT project lifecycle. The developed three frameworks are detailed individually in the following paragraphs. The developed IT project(s) selection framework utilised information economics theory to encompass the full spectrum of direct and indirect costs, tangible and intangible expected benefits and the intangible risks associated with IT project proposals, considered for funding by the organisation. To incorporate the uncertainty that normally surrounds quantifying costs, benefits and risks, the framework employed a simple but powerful fuzzy logic technique to integrate all the monetary and non-monetary factors into a form that enabled the ranking of proposals. A case study was undertaken with a large international project management and development organisation to demonstrate the framework's applicability. The case study illustrated the effectiveness of the proposed approach for ranking IT project proposals. Once a portfolio of IT projects is selected for funding by the organisation, it needs to be strategically implemented and monitored over its lifecycle. A strategic IT implementation and monitoring framework was developed to enhance the effectiveness and efficiency of this phase. The framework is premised on a hybrid analysis utilising the Analytical Hierarchy Process (AHP) and SWOT analysis. A case study was undertaken to demonstrate the applicability of the proposed framework in the strategic implementation and monitoring of a Project Management Information System (PMIS) by a large Australian construction-contracting organisation. The framework application proved to be successful in helping the organisation to develop appropriate strategies for the effective and efficient implementation of the PMIS. An IT performance evaluation framework and method was then developed for the final phase of the lifecycle. This framework was the primary focus of this Ph.D. research study and was structured using the Balanced Scorecard (BSC) principles adapted to the specific requirements of the construction industry. The framework was structured using a hierarchy of IT performance perspectives, indicators and measures. Five definable perspectives were conceptually developed through analysis and synthesis of the 'IT business value' evaluation literature. These are: operational, benefits, technology/system, strategic competitiveness and user orientation. Indicators and measures were extracted from the mainstream IT literature and construction management literature, as well as the emerging literature on information economics. The preliminary list of indicators was initially screened through consultation with construction professionals and conceptual cause-and-effect mapping. The screened list of project-tier indicators was further refined through questionnaire dissemination. The questionnaire was sent to 322 construction project participants from large construction-contracting and project management organisations located within Australia. The five framework perspectives were statistically validated through the principal component factor analysis with varimax rotation. Each perspective and indicator's relative weight was numerically established using the questionnaire survey results as input to the recently developed Performance Measurement Process Framework (PMPF). The reason that the performance measures were not justified through a quantitative analysis was due to their dynamic nature. Most performance measures change, and will continue to change, with new technology. The developed perspectives, indicators and measures were all compiled into a generic 'Construct IT' BSC that can serve as a template for application at other decision-making tiers of a construction organisation. The problem of combining performance measures, with varying metrics, into commensurable units (utiles) was achieved by applying utility theory. Finally, the developed 'Construct IT' BSC was utilised for a project-tier survey to test the interrelationship between framework indicators and perspectives. Using information collected from 82 project professionals, from large construction-contracting and project management organisations, correlation and independent sample t-tests (one-tailed) provided support for the 'Construct IT' BSC. Specifically, findings suggest that the 'Construct IT' BSC can be used as a tool for monitoring the IT-induced value creation process. In addition, it appears that the proposed 'Construct IT' BSC framework and associated performance evaluation method is both flexible in design and can be modified to suit the needs of individual organisations. These characteristics make the framework continuously relevant to the dynamic nature of IT projects. In summary, the proposed IT project lifecycle management process, and its associated frameworks, provides a holistic view of IT implementation in construction and offers significant contributions to current body of knowledge on IT in construction.

Odigie, Hendrix. "Technology transfer strategies and practices in Nigerian construction organisations." Thesis, University of Salford, 2012. http://usir.salford.ac.uk/26843/.
Full textAbstract:
There is no doubt that Technology Transfer (TT) activity from the transferees' view point is an important issue when it comes to economic development, especially in developing countries. This present study is concerned with Technology Transfer Strategies and Practices (TTS&P) within/between Nigerian construction organisations, from the transferees' perspective where emphasis is placed more on the indigenous construction organisations. The aim of this study is to develop a framework of TTS&P for Nigerian indigenous construction organisations. This study recognised the importance of collaboration in any Technology Transfer (TT) activities, as Technology Transfer (TT) is a give and take process. Therefore, the study investigated Technology Transfer Strategies and Practices (TTS&P) from both indigenised foreign construction organisations and indigenous construction organisations in Nigeria. It investigated the current Technology Transfer Strategies and Practices (TTS&P) employed, the effectiveness of Technology Transfer Strategies and Practices (TTS&P), the Critical Success Factors (CSFs) that influence the implementation of Technology Transfer Strategies and Practices (TTS&P), the benefits and challenges associated with Technology Transfer Strategies and Practices (TTS&P). Evidence from literature revealed the need for TTS&P in Nigerian indigenous construction organisations. It also revealed that there are very few studies on TT that have been undertaken in developing countries, whilst no study has been done on TTS&P, especially in Nigerian construction organisations. The objectives of this empirical study were to explore TTS&P within Nigerian construction organisations. The research adopted an interpretive stance and employs multiple data collection methods. It employed a combination of both postal questionnaires and semi-structured interviews. A total of 143 completed questionnaires representing 108 questionnaires from indigenous construction organisations and 35 questionnaires from indigenised foreign construction organisations, formed the data base for the quantitative analysis. The qualitative data were from 23 semi-structured interviews (9 interviews came from indigenised foreign construction organisations and 14 interviews from indigenous construction organisations). The study concluded that organisational alliance through technology transfers are growing and the potential benefits of such organisational arrangements are not being realised because participating organisations are emphasising on short-term profit sharing to the detriment of more long-term and ultimately, core value-added, dimensions of knowledge creation and organisational learning. The study therefore recommended a long-term collaboration that would embrace technology transfer strategies and practices which would encourage construction organisations to move away from their traditional client-contractors relationships to more contractorscontractors- clients relationship for more knowledge, skills and techniques sharing processes. This study was limited to Nigerian construction organisations, especially the indigenous construction organisations, but can be generalised and thus applied to other organisations that exhibit similar characteristics.

In developing and constructing process models, a large amount of data is generated. This needs to be stored as information by providing context (e.g. description and units), such that it may be accessed and Understood by both human users and computer tools. To be useful, information sets must be chronicled by recording information such as by whom it was generated, when, and using what tool. Links should also be maintained between related sets of information to document the relationship. The World Wide Web (WWW) facilitates the provision of links between documents. It may, amongst other things, be thought of as a globally addressable file system. Accessed by a graphical tool, the browser, it can provide a common user interface to access and interact with documents across disparate operating systems. Documents on the WWW include hypertext links, which enable one document to link to another. This thesis describes an object-oriented system which makes use of the www to chronicle process model construction. The object-oriented paradigm has been used to provide a convenient mechanism for encapsulating data in a structured framework. As well as containing the object data, objects also contain information on who created the object, at what time, etc. This information may be used to generate a browsable history of object creation. Objects are stored as www documents, and may be created, viewed and manipulated using standard browsers. An application programmer's interface has been written which enables the information to be manipulated via Fortran programs. Objects have been developed for standard process engineering entities such as streams, mixtures, components, process topologys, etc. Once created, these may be used to generate simulation models in a variety of formats, e.g. ASPEN, spreadsheet model, etc. Conversely, process objects may be generated from ASPEN models. Four case studies have been included, showing various applications of the system. In conclusion, the www provides a suitable environment for implementing such a system, due to its ease of use, and the fact that it provides both a user interface and enables remote access to the system.

Full textAbstract:
Usability has long been considered an important component of an innovation (Norman, 2002), evidenced by the fact that usability research has dominated innovation design efforts for a number of years. However, recent research has shown that satisfying usability is not sufficient for the successful diffusion and adoption of an innovation (Karsh, 2004). To develop an useful innovation, one must understand the mechanisms by which people choose to adopt and use an innovation, as well as how an innovation fits different levels of a socialtechnical system (Karsh, Escoto, Beasley, & Holden,(2006). The goal of this research, therefore, was to develop an innovation analytic and design framework that would enable designers to design a more likely adopted innovation and to validate it through the design and evaluation of a fall-protection training intervention for residential roofing subcontractors.
The proposed innovation analytic and design framework was based on the traditional systems-engineering process: Requirement Analysis, Prototype Development, and Summative Evaluation. Rogers’ Theory of Innovation Diffusion and Adoption, as well as Participatory Design, were utilized to obtain a holistic view of technology-adoption challenges and opportunities.
The requirement analysis involved the development and use of a questionnaire and semi-structured interviews to identify the contributors of safety technology adoption in small roofing companies, as well as to understand the practices of safety technology adoption and fall-protection training. One hundred and four questionnaires from workers in North Carolina and Virginia were collected, and 29 workers received the follow-up semi-structured interview. Results showed that (1) social influence had a significant impact on the diffusion and adoption of safety technology; (2) workers’ satisfaction with existing safety performance standards/practices, as well as disengagement during available safety training, caused difficulties in implementing regular safety training; (3) management commitment and presentation of good/bad consequences of unsafe behavior were expected to facilitate the rate of adoption of safety technology. Results also identified specific recommendations for a fall-protection training intervention.
The prototype development was performed by a six-member Participatory Design (PD) team in a PD workshop, who used the results of the questionnaire and semi-structured interviews to develop a training intervention. Four PD approaches (PICTIVE, Inspiration Card Workshop, Scenario Building, and Future Workshop) were employed in the development of a Personal Fall Arrest System (PFAS) as an industry-specific training intervention.
This research also used summative comparative evaluation to assess the developed PFAS training intervention against a standard PFAS training intervention with respect to (1) adoption propensity, (2) expected adoption outcome, and (3) results demonstrability. Eighteen roofing workers were recruited to evaluate and compare the two interventions. The standard PFAS training intervention was developed by two experts using the safety manual published by the National Roofing Contractor Association. Results suggested that (1) the developed PFAS training intervention was more likely to be adopted and easier to diffuse among roofing subcontractors than the standard PFAS training intervention, and (2) use of the developed PFAS training intervention would better improve company's safety performance in comparison to the standard training intervention. Results of the evaluations confirmed the efficacy of the proposed innovation analytic and design framework in designing a more likely adopted innovation.<br>Ph. D.

Full textAbstract:
This cooperative research work is concerned with the development of fall arrest equipment constructed from textile materials for use in mountaineering, caving and industrial safety applications. The range of webbings available for use in fall arrest equipment is examined, and some basic experiments to determine the effect of severe abrasion are described. The methods of stitching slings (loops of webbing) are examined, and the effects of external abrasion on conventional lap joints and bartacked joints are compared. The development of harnesses is examined and the factors affecting their future design are considered. The major part of the work is concerned with the way in which the energy of a falling body is absorbed in a fall arrest system and with the peak impact loads imposed on the system's components. To measure these loads, apparatus was developed at the cooperating company's premises, together with appropriate instrumentation. A series of tests were carried out to determine loads in falls of increasing severity. The ensuing development work concerned textile shock absorbers, which are designed to limit the impact force in a fall to a predetermined maximum. Using the drop test apparatus, it was shown that such shock absorbers have very little practical effect in a climbing situation. However, the principles embodied in these devices were used to develop an industrial safety lanyard with an integral shock absorber which conforms to British Standard 1397. This device is lighter and more compact than others currently on the market and represents a step forward in the field.

Full textAbstract:
Innovative technologies for construction project management are constantly emerging in the construction industry's global landscape, yet the rate of failed projects within the Nigerian construction sector due to poor coordination of construction tasks is on the rise. An unanswered question in the literature remains as to why construction project managers in Nigeria remain slow to adopt new technologies for improving decision-making processes and project success rates. The purpose of this qualitative single case study with embedded units was to understand the perceptions of construction project managers in Nigeria regarding their barriers to technology adoption. This study was framed by 2 conceptual models: Usman and Said's model of factors contributing to information and communication technology adoption in Nigerian construction firms and Waziri, Mustapha, and Idris' model of factors influencing IT adoption in Nigerian construction organizations. Semistructured interviews involving 10 participants, reflective field notes, and archival data provided information regarding the barriers to technology adoption experience of construction project managers in Nigeria. Thematic analysis of the textual data and synthesis produced 5 conceptual categories for 14 identifiable themes from the study. The conceptual categories were (a) adoption of technology, (b) culture, (c) organizational performance, (d) innovative technology, and (e) interorganizational collaborations. The findings from this study may serve as a catalyst for positive social change by challenging existing technology-avoidance behavior in the Nigerian construction industry, and opening new opportunities for improved project delivery in the Nigerian national economy.

Full textAbstract:
The idea that the deployment and strategic utilization of information technology (IT) resources as factors of production can be used by organisations to improve performances has been around for many decades. The contributions of the IT resources in improving organisation’s performances give rise to what is termed IT business value (ITBV). There have been varieties of conceptualizations and attempts to measure the ITBV by different researchers. However, most of these attempts to quantify ITBV have led to inconsistencies and paradoxes. Furthermore, a major part of the literature in the area continues to be anecdotal and primarily descriptive. Therefore, there is little evidence of an accepted theoretical framework for applying the ideas and there is even less in the way of empirical evidence concerning the validity and utility of these concepts. The research adopts multi-theoretical concepts of process-based, resource-based and microeconomics views as the theoretical framework in order to mitigate the absence of structured theoretical framework in the previous studies. A non parametric approach of Data Envelopment Analysis was used for empirical testing of the model developed. The findings present an empirically tested model for benchmarking IT-induced productivity in construction industry. Also the outcome of the research establishes that IT provides business value in undertaking the engineering and construction business processes, which leads to significant impact on the organisations performances in the areas of project delivery, customer relationship and overall profit growth. For practical purposes, the model could be used to provide support to managers in decision making on IT investments, utilization of the IT resources and how combination of strategic IT resources with other organizational resources could in increase efficiency in delivering project value chains.

The first TES system that is being constructed is the submerged parallel spiral heat exchanger which is a completely new version of latent heat storage to be tested. For this idea, parallel layers of spiral copper coils will fill up a tank shell which in turn will be filled with phase change material. By injecting high temperature heat transfer fluid, phase change material will change its state and energy will be stored in the system. When injecting low temperature heat transfer fluid, the energy will be extracted. This BSc thesis will present detailed design solutions for the tank shell and the spiral copper coils that will be used for the heat exchanger. Presented solutions are then used to order parts needed to initiate the construction phase.<br>Inom ramverket för 2020 PUPM HEAT projektet kommer tre olika typer av värmeenergilagrings enheter tillverkas och analyseras vid energikraftverket IREN i Moncalieri, Italien. KTH kommer att assistera detta projekt genom att sätta upp en anläggning med tre liknande värmeenergilagrings enheter i mindre dimensioner som kommer konstrueras och analyseras. Dess data kommer sedan användas som riktlinje för att tillverka de större värmeenergilagringsenheterna i IREN. Den första enheten som tillverkas är en värmeväxlare som bygger på en ny version av latent energilagring. Den kommer att bestå av parallella lager av spiral formade koppar rör som fyller en tank. Tomrummet som blir över kommer att fyllas upp av fasändrings material (PCM). Genom att injicera varmt vatten i systemet kommer PCM:et att byta fas, vilket resulterar i att värmeenergin lagras i systemet. När sedan kallt vatten injiceras kan den sparade energin bli utvunnen. Den här rapporten kommer att presentera designen till tank kåpan såväl som den inre strukturen med kopparrör som behövs till värmeväxlaren. Resultatet ska möjliggöra beställning av alla delar som behövs för att konstruera värmeväxlaren.

Full textAbstract:
In recent years, the construction industry has been compelled to explore all possible options for improving the delivery of their products and services. Clients are now expecting a better service and projects that meet their requirements more closely. This has challenged the industry to become more efficient, integrated and more attractive, with benefits for its potential workforce and for society as a whole. Information and communication technologies (ICT) are an enabler to facilitate the improvements required for modernisation. However, due to the geographically dispersed and nomadic nature of the construction industry's workforce, many people are prevented from efficiently and effectively using the ICT tools adopted to date. Mobile technologies providing the 'last mile' connection to the point-of activity could be the missing link to help address the ongoing drive for process improvement. Although this has been a well-researched area, several barriers to mainstream adoption still exist: including a perceived lack of suitable devices; a perceived lack of computer literacy; and the perceived high cost. Through extensive industry involvement, this research has taken the theoretical idea that mobile IT use in the construction industry would be beneficial, a step further; demonstrating by means of a state of the art assessment, usability trials, case studies and demonstration projects that the barriers to mainstream adoption can be overcome. The findings of this work have been presented in four peer-reviewed papers. An ongoing dissemination programme is expected to encourage further adoption.

Full textAbstract:
There is an increasing number of construction products that are manufactured globally through complex supply chains. The results of this is that quality requirements are increasing and the construction industry look towards ways to reassure the sustainability of the materials in their supply chains. The aim of this study is to explore how the new blockchain technology may be used to meet today´s and future requirements of the construction industry and analyze the potential consequences of using the technology. Our work examine how the blockchain technology can support supply chain transparency and material traceability. To explore and analyze how the technology may affect the supply chain of a specific material a case study has been carried out. The task has been focused on how a specific material is handled throughout a suppliers supply chain, from where it originates until final use by a contractor. A hypothetical supply chain has been set-up and analyzed in terms of transparency, traceability and the potential consequences of using the blockchain technology. We have specifically focused on how the blockchain system could be set-up, who should own the blockchain system and what are the sustainable aspects of using blockchain. The conclusion is that blockchain technology can improve the transparency throughout the entire supply chain. However the need for a complementary technology is needed in order to handle all the problems with traceability. One example of this complementary technology is RFID tagging. Furthermore, some of the consequences that has been identified are; it improves the way to handle supply chain documentation, the reputation of the industry improves, the possibility to remove third party organs increases.<br>Med ökat antal byggmaterial som tillverkas genom globala komplexa försörjningskedjor ökarkvalitetskraven inom byggbranschen samt behovet att säkerställa hållbarheten hos dessamaterial. Syftet med denna studie är att bedöma hur blockkedjeteknik kan användas för attsäkerställa dagens och framtidens krav på byggindustrin och analysera dess potentiellakonsekvenser vid ett användande av tekniken. Detta arbete undersöker följaktligen hurblockkedjeteknik kan stödja transparens och spårbarhet i leverantörsledet.För att analysera hur tekniken kan påverka en typ av byggmaterial har en fallstudie utförts isyfte att kartlägga ett leverantörsled. Fallstudien har fokuserat på hur materialet hanteras, fråndess ursprung tills att det anländer till byggarbetsplatsen. En hypotetisk leverantörskedja harkonstruerats och analyserats i termer av transparens, spårbarhet och vilka olika konsekvenserdet kan medföra. Vi har speciellt fokuserat på hur blockkedjesystemet kan konstrueras, vemsom ska äga systemet och hållbara aspekter.Slutsatsen är att blockkedjeteknik kan öka transparensen genom hela leverantörsledet. Detfinns emellertid ett behov av komplimenterande teknik att lösa spårbarhet. Ett exempel pådenna komplimenterande teknik är RFID taggning. Slutligen har ett antal konsekvenserfastställts vid ett användande som är; hanteringen av dokumentationen förbättras, ryktet inomindustrin förbättras och möjligheten att ersätta tredjepartsorgan ökar.

Full textAbstract:
It is envisaged that flood plains will be put into more active usage to meet the increasing demands for road infrastructural development as well as relieve the pressure exerted on arable lands owing to infrastructural development activities. This is consequent upon the general shortfall in the availability of soils possessing the right engineering properties to carry infrastructures such as roads which consume large tracks of land. Expanding the global infrastructural base is inevitable due to the ever increasing human population and the need to meet their social, economic, political and transportation needs. However, owing to the prevailing environmental awareness campaigns fronted by different environmental agencies, there is the need to regulate and monitor the interaction of the processes involved in the provision of these needs with the limited resources as well as the environmental aftermath associated with such operations. The stabilization of flood plain soils for road embankment construction is envisaged to reduce the demand on the material resources required to build classical high embankments in flood prone areas as well as offer implied mitigating dimensions in the restoration of environmental integrity. This impliedly will reduce the use of traditionally unsustainable methods of soil stabilization such as, the excavation and importation of new materials, to a more robust system that will offer environmental friendliness amidst value engineering for better strength and durability results. The experimental processes involved the simulation of flooding scenarios in the laboratory, to monitor the strength and durability aspects of low-bearing-capacity soils (such as Lower Oxford Clay) stabilized with blended mixes of the traditional stabilizer of lime and the novel materials of lime and Ground Granulated Blastfumace Slag (GOBS) by-product combined. Preliminary investigations were carried out on the Lower Oxford Clay soil to establish the moisture and compaction requirements of the material. Different mix compositions were formulated by incrementally replacing the amount of lime in the system with GOBS. This was based on the premise that high stabilizer contents could offer better stabilization to flood susceptible geo-materials upon flooding. A high stabilizer level of 16% was therefore investigated. Regimes of different blending ratios were established as follows: 16%Lime-0%GGBS, 12%Lime-4%GGBS, 8%Lime-8%GGBS, 4%Lime-12%GGBS and 0%Lime-16%GGBS and tested at moisture contents of 23%, 28%, 33% and 38%. The two extremes 16%Lime-0%GGBS and 0%Lime-16GGBS were used as controls. A system of elimination based on strength criteria was employed, where only the 8%Lime- 8%GGBS and 4%Lime-12%GGBS mixtures were deemed fit to be investigated further to determine their resistance to challenging environmental factors of flooding. The test samples were cylindrical, measuring 50 mm in diameter and 100 mm long, and these were compacted using a static compaction apparatus to achieve Maximum Dry Density (MDD). Depending on the testing regime to be applied to a given specimen, a curing pattern was defined and samples were wrapped in cling film to minimise moisture losses. At the end of each curing period of 7, 14, 28, 56 and 90 days, one of the experimental procedures which ranged from Unconfined Compressive Strength, Water Absorption, Volume Stability, Permeability, Soaked Strength and Durability Index Assessment or Compressibility Assessment was carried out on the moist cured samples. Following these assessments, the 4%Lime-12%GGBS mix composition was appraised to have overall improved characteristics with the added benefit of reduced cost of material utilisation. Based on the available data, regression analyses were carried out and equations established for predicting the strength values of stabilized materials. Using these equations further extrapolations were made and the observable trends were those of the dependence of compressive strength on the age of moist curing and the compaction moisture contents at which samples were produced at given blended mixture. Cost-benefit-risk analysis was also carried out with a further cost annualisation of the capital and operational cost of a selected system. It is reassuring to learn that at replacement level of lime with GOBS of 4%Lime-12%GGBS it was possible to establish multi-binder mixtures that could be effectively used for sustainable construction in flood prone areas with enormous savings accruing from the possible higher strength and enhanced durability indices achievable over traditional unsustainable options of continued over-reliance on lime and Portland cement.

Full textAbstract:
The inability of the Iranian construction industry to satisfy the country's massive housing demand has transformed housing demand and supply into one of the major challenges facing the government. 1.15 million residential units need to be built each year for the next ten years. The Iranian construction industry is suffering from various deficiencies such as low productivity, small and unprofessional developers, huge waste, skilled labour shortages, defective management, unstable economy, severe fluctuations in demand and supply etc. Considering the potential advantages of Modern Methods of Construction (MMC), the general belief is that the application of MMC will resolve may of the above issues. Meanwhile, Iran needs to learn from the experience of other countries such as the UK to avoid repeating their mistakes. MMC is a more complex subject in which various issues including standardisation, coordination, management, design, costs, sustainability, risks, etc, should be considered. Some of the above have become more important than others for Iranian stakeholders but prioritisation and partial consideration of these issues will not be effective. This study intends to investigate the viability and applicability of the UK's advanced construction systems in Iran. For this reason, several criteria including the building regulations and standards, practicality, economy, costs, culture, sustainability, and design have been addressed, and both countries compared with regards to these issues. The results show that, although MMC can theoretically enhance the current situation of the construction industry, issues such as education and research, industry, economy etc., need to be addressed in order to have successful application of MMC in Iran.

It is argued that a fundamental criterion which has received little consideration in the investigation of cost prediction is the impact of information upon accuracy. An information model is developed by drawing on the work of communication engineers, information scientists and psychologists. It is then demonstrated that information cannot be divorced from the knowledge of the receiver and as such it then becomes necessary to determine how knowledge is accumulated and how this then impacts upon the need and demand for information, the choice of relevant information, as well as how that information is utilised. The concept of relevance is considered from a logical and psychological perspective. On completion of this analysis the information model which links cost estimating with entropy, information and knowledge is completed. It is argued that the developed model is comprehensive and facilitates the progression of research in this field. The model is then used as a basis for the investigation of the relationship between information and expertise in estimating, choice of information for estimating, impact of information on estimating, perceptions of information quality and the perceptions of the importance of information facets and attributes to the estimating process.

Full textAbstract:
Background: The construction industry is usually regarded as a traditional sector, owing to its specificities, within which the implementation of advanced technology and online work procedures is difficult and consequently, virtuality is perceived as detrimental to team performance. However, the COVID-19 outbreak has forced the whole sector to a rapid transition to remote working. Objectives: The main purpose of this study is to understand how communication and collaborative online technologies, along with different leadership and managerial skills, influence virtual hybrid team performance within the construction industry. In addition, the analysis is intended to validate the conclusions of previous studies on factors impacting hybrid team effectiveness in construction projects. Methodology: The research process has been carried out through quantitative methods and the use of an online survey that has obtained more than 300 responses from engineers and architects. The data have been statistically analyzed through Structural Equation Model (SEM) following a Partial Least Squares (PLS) approach. Finally, a short number of direct questions have been included in the questionnaire, to contrast the results and verify their validity. Results: First, the analysis has not supported that virtuality is detrimental to team performance. Second, technology has been confirmed as a decisive factor to ensure leadership effectiveness in virtual environments. Third, the study demonstrates that technology and leadership act as moderators between virtuality and team performance when applied together. Fourth, the influence on team performance is more positive for conferencing and collaborative tools, followed by project management and BIM platforms, and basic communication tools. Fifth, all four internal leadership roles are important to achieve team performance; the mentor and facilitator roles are deemed more influential, followed by the coordinator role, and finally, the monitor role. Last, the usage of adequate technologies and effective leadership impacts more decisively on quality and client satisfaction. Conclusions: The main conclusion is the realization that virtuality is less influential to team performance than expected. Another interesting finding is the general agreement on the feasibility of a higher amount of remote work which opens the door to new organizational procedures. The analysis has also shown that, to date, the poor implementation of BIM platforms has not allowed virtual hybrid teams to take advantage of this technology. Further, future construction leaders will require special training to achieve high performance in virtual environments. Finally, the search for quality in the sector, as a prerequisite for profitability, demands special care be taken in any decision regarding technology and leadership. Recommendations for future research: A similar study following qualitative methods would be of interest to validate the results of the analysis. Likewise, the repetition of the study, once the COVID-19 pandemic has finished, will allow future researchers to verify its conclusions under ‘normal’ circumstances. Finally, the generalization of the results can be achieved by enlarging the study to other countries and continents, and also, to other groups of professionals that take part in construction projects.

Full textAbstract:
碩士<br>國立成功大學<br>土木工程學系碩博士班<br>91<br>Construction management studies address mostly the phenomena of construction problems. Although many analyze the cause-effect relationships of real issues, few studies explore the nature of construction technology (production system).
The government has promoted the construction automation programs to advance production efficiency for past years. Moreover, the issue of electronic business also has been included recently. The progress of automated construction systems is slow comparing with it in the manufacturing industry. It may be limited by the nature of construction technology. Thus, we should examine and understand the construction technology fundamentally before pushing successive construction automation and e-construction programs.
There had been longitudinal and latitudinal research on technology in the manufacturing industry, which could be served as the basis of exploring the nature of construction technology. For an enterprise to operate efficiently and successfully, its production system and organization should be compatible with each other. By in-depth interviews with experts, this study implements a systematical analysis about the present conditions of construction organizations from the aspects of organizational structure, process, and behavior. With the analysis, we can examine whether the work and conditions of construction organization is compatible with the needs of its technology, and find out the fundamental problems of construction improvement. Furthermore, this study also processes a complete review for the past and future direction of changing technology, and proposes practice suggestions to advance the construction industry.
The findings of this thesis show that automation is difficult for the construction industry, but there is room to apply e-construction. Although the efficiency of construction technology as unit production is low, it has many advantages such as high flexibility, zero stocks, and satisfactory human social needs. With the appearance of new production systems such as mass production and continuous production, it doesn''t mean that the old unit production will be replaced. Even though the final construction products couldn’t be standardized entirely, we can standardize their components, and fundamentally rethink their assembling and integrating methods to increase production efficiency. Construction industry should reserve the advantages of its present production system, and pursue the advancement of managerial efficiency.

碩士<br>國立高雄應用科技大學<br>土木工程與防災科技研究所<br>101<br>With the development of globalization and information technology (IT), companies are switching from the competition strategies focusing on mass production to customized models of cost reduction, fast response and flexibility. In this era of knowledge economy marked with massive competition stress, technology innovation capability has become the key for companies to maintain their competitiveness. The past studies mostly focused on the connections between construction project characteristics and project performance to explore how to improve the general construction efficiency. Few of them discussed the influences of IT competence, relationships with property owners, and technology innovation capability of construction companies on their project execution performance.
The subjects of this study are mainly practictioners in the construction industy in Taiwan. Totally 200 questionnaires were sent with 161 valid samples returned. The returned samples were statistically analyzed using SPSS and the analysis results were used to reach the following findings and suggestions:
1.The sample structure analysis results indicate that the subjects relatively highly agreed that the construction
companies in Taiwan have good IT competence (average score=5.20 points), relationships with property owners
(average score =5.26 points), and construction project performance (average score =5.26 points). However, the
subjects slightly agreed the construction companies in Taiwan have technology innovation (average score=4.91
points).
2.Through the correlation analysis, it was found that a company’s IT competence, relationships with property owners,
technology innovation and construction project performance are significantly and positively correlated with each
other.
3.The path analysis in this study found that in the dimensions of a company’s IT, relationships with property owners
and technology innovation, the technology innovation capability has a significant influence on the construction
project performance (R2=0.524), indicating better technology innovation capability will be helpful for promoting
better construction project performance. In addition, in the dimensions of a company’s IT, relationships with
property owners and technology innovation capability, IT (F=34.117**, p<0.01) and relationships with property owners
(F=87.498**, p<0.01) each has a significant influence on the company’s technology innovation capability.

碩士<br>中華大學<br>土木工程學系<br>106<br>In recent years, with the construction of large-scale public infrastructures, such as
construction of traffic bridges, high-rise buildings, factories, etc., the frequency of use of
piles has become more and more frequent, especially the full-casing piles have been widely
used. Therefore, it is necessary to further study the characteristics of the construction of the
whole casing pile. This study will focus on the full-casing construction to explore its
engineering characteristics in different situations.
In order to obtain the relevant problems in the practice of the whole casing pile
construction technology, this study carried out a series of related cases and possible
problems in practical problems. The research results show that the full casing pile has
many advantages, because the drilling process has the steel casing prevents the soil from
collapsing, so that the pile quality is good, and it can be applied to various geological and
topography with different drilling equipment and excavation facilities, and has
considerable experience in different geology and topography for practical use. For quite
mature work methods.
In addition, through the special case study in practice, due to the advantages of small
construction space, simple tools, flexible movement, etc., the special casing geology and
the lack of base space can be used to make semi-circular retaining piles. The section of the
soil facility is halved, and the available area of the basement is increased. The construction
speed can shorten the construction period, reduce the project cost, increase the land and
project expenditure to achieve the maximum benefit.

20 years in Taiwan. Especially, Flat Kaiser truss boards, is
common applied by internal company. There*re a lot of blind in
the applied process of designing and constructing, meanwhile,
causing serious battlements in the chain of construction quality
controlling. In the surrey process for KT slab construction
designing method. We find that, most of internalcompanies,
directly use 「Kaiser board designed, manufacture, construction
point」and「Kaiser wall-panel designed, manufacture,
construction point」from Japanese company. Since the shortage of
the relative experience, and then, produce the opinion seems
correct concert. But, the KT Board Construction method of
designed and constructive technology guideline result in
technique. For ordering the planning method or process by
conference of professor*s opinion and the conclusion of
symposium, in the process, lack of the internal original mode,
the present method cannot meet the demands for internal
condition.So, it*s necessary to researching of the flat Kaiser
Truss Board Construction method of the designed and constructive

碩士<br>嘉南藥理科技大學<br>環境工程與科學系暨研究所<br>95<br>For the past three decades, constructed wetlands have become an effictive and low-cost ecological technology for water pollution control. Sealing the basin by using the liners is one of the important design and construction works of constructed wetlands. Its aim is to prevent the contamination of groundwater or prevent groundwater from infiltrating into the constructed wetlands. At the present, there is still a lack of suitbable evaluation workflow that is in line with local conditions for sealing the basins of constructed wetlands, which can be used as reference for the design and construction of constructed wetlands. This thesis collected on-site soil from 13 different sites in sourthern Taiwan and tested their various proterties in the lab, including: particle size distribution, effective size, soil texture, and hydraulic conductivity. By using soil compaction experiment and the experiment of adding material of low hydraulic conductivity, an effective method to line the constructed wetlands will be developed, and a standard workflow for evaluating a suitable lining method through considering on-site soil properties will be established.
The result of soil texture analysis shows that clay content of the soil samples from 13 different sites was about 10~27%, silt content 13~67% and sand content 10~75%. Nine of the soil samples was determined to be silt loam, one to be loam, and three to be sand loam. The hydraulic conductivity of soil in the Moon World mud pool was the lowest, 6.40×10-7 cm/sec; the hydraulic conductivity of soil in the Erh Hang village and Golden Seacoast is the highest, 5.7×10-4 and 1.96×10-3㎝/s, respectively. The hydraulic conductivity of soil was found to be exponentially proportional to effective sizes of soil grains (D20, D30, D40 or D50). The hydraulic conductivity (K) has higher corelation with D30 than other effective sizes, the corelation equation is K=0.01×D301.21945 (R2=0.72), which can be considered as an useful emperical model for estimating hydraulic conductivity of soil from other areas.
This study also examined the corelation between the hydraulic conductivity of soils and the three elements contents of soil texture properties by using the way of multi-variables regression method. The result shows that the regression equation with higher corelation coefficient was obtained when hydraulic conductivity was related with all the three elements contents simultaneously (R2=0.659), while regression equation with lower corelation coefficient was found, if hydraulic conductivity was related with contents of two elements or single element. The multiple variable regression equotion is:
Which can aslo be applied to estimate the hydraulic conductivity of soils.
Soil samples obtained from five various sites were used to conduct the soil compaction experiment. The result shows that the amount of water addition and tapping times are the key factors that affected soil compaction result, when compacting soil. When compacting at water addition of 13.2~14.6%, under the same tapping times, the hydraulic conductivity of compaction soil sample is obviously lower than at water addition of 9.0~9.6%. But when water addition amount rose to 17.3~18.9%, the hydraulic conductivity of compacted soil did not further effectively reduce. In addition, under the same amount of water addition, the hydraulic conductivity of compacted soil decreased with the increase of tapping times; however, when tapping were over 30 times, the increase of tapping times had no obvious effect on the decrease of hydraulic conductivity. The addition experiment of low hydraulic conductivity material shows that with enough water addition, compared with the soil group without adding bentonite, the hydraulic conductivity of the soil group that with little addition of bentonite(2~5%) decreased about more than 30%, and achieved to a criterion ＜1×10-6 cm/sec. The experiment also proves that using commercial and easily available material, bentonite, which needs only small amount addition, can replace the natural soil of high clay content, which needs comparably high amount addition, to reach the result of decreasing hydraulic conductivity of soil. This method can be used as alternative and effective construction method for the liners of constructed wetlands. This study finally established a workflow for evaluating the best construction method of liners of constructed wetlands, which could provide a guideline for the site selection, plan and design of constructed wetlands.
