Abstract: Poor construction administration performance is a significant cause of inefficient construction process which is a major problem for construction projects in Nigeria. This research developed a model to appraise the contract administration performance of construction project. A total of ninety-three (93) construction administration process grouped into eleven (11) phases were rated by expert respondents in a questionnaire survey. A Structural equation model between the construction contract administration performance (CCAP) and the eleven (11) Construction Contract Administration (CCA) phases which include the governance and start-up management (GS), team management (TM), communication and relationship management (CR), document and record management (DRM), claims and dispute resolution management (CDM), performance monitoring and reporting development (PR), financial management (FM), quality and acceptance management (QA), changes and change control management (CM), contract risk management (CR) and contractor close out management (CCM) were developed. From the resulting model generated, PR, QA and GS had the highest influence on CCAP with model coefficients of 0.977, 0.962 and 0.954 respectively, while the least influential is CR with coefficients of 0.744. This further enunciates the importance of monitoring to the overall success of all contractual obligations of a construction project.

Abstract: South Sulawesi is one of Indonesia's provinces with great potential in the construction sector. However, South Sulawesi faces various challenges in the construction sector, including construction disputes. This study aims to analyze the factors that cause construction disputes between small, medium, and large construction companies in South Sulawesi. Data were collected using questionnaires to project stakeholders and previous research. The method used was Structural Equation Modeling with a Partial Least Squares system. Seven factors cause disputes in construction projects, namely the problem of completeness of working drawings, changes in plan drawings, administration of approval of drawing changes, legal factors, weather change time factors, non-achievement of planned building quality, and increases in material prices and wages. The influential factors are time 67.8%, administration 53.8%, cost 48.0%, quality 45.2%, human resources 44.4%, technical 39.8%, and legal 39.2%. Thus, the time factor is the most influential in construction disputes in South Sulawesi.

Abstract: Rukoh Dam is one of the structures that can increase the reliability of providing raw water for various purposes. The dam is expected to be able to accommodate excess water during the rainy season and anticipate water shortages during the dry season. The Rukoh dam is located in the flow of the Rukoh crew which will be assisted by the directional channels from the Inong Tiro crew dam to provide sufficient water drainage. This research aims to identify work items based on functions to ensure that the application of Value Engineering (Value Engineering) can or can not be carried out on the Rukoh Dam Irrigation Tunnel Construction Project Pidie Regency. The function analysis stage is the most important stage in value engineering because function analysis is what differentiates value engineering from other cost saving techniques. The process carried out is to identify work items through functional analysis based on their function in comparison of cost with value. From the Pareto analysis and graph, there are two high-cost work items, namely the Kr Inong supply and tunnel work. However, the cost-savings review was carried out only on suppletion duct work. At this stage of function analysis, it is known that the carrier channel structure work produces C/W ˃ 2.59, which means that it is indicated that there are unnecessary costs so that it can be continued to the next stage.

Abstract: The existing literature shows that organizational culture has a significant impact on its performance. However, few studies probe into their relationship in the context of project. This study examines the impactmechanism of organization cultureon project performancethroughorganizational citizenship behavior (OCB) in the construction projects. A survey on 451 professionals served in the construction projects is conducted. The findings demonstrate that organizational culture influences project performance significantly. And clan culturehas greaterpositive effectsonproject performance than other three culture domains. The results also indicate OCB partially mediates the impact of organizationalcultureon project performance. These findings suggest that organizationalculture can be used by project managers as a lever to exert citizenship behaviors among project members and eventually improveproject performance. The managerialimplications are discussed.

Abstract: The construction industry plays significant role in the economy of developing countries, where Lebanon is one of. However, the performance industry remains under critique. Many projects encounter considerable time and cost overruns, fail to realize their intended benefit or even totally terminated and abandoned before or after their completion. As the construction project goes through many phases, the success of each phase will affect the success of the project. Thus, the “Project Success” notion is becoming a priority in the Lebanese construction sector. This paper describes a study of the time, cost and quality management trilogy impact on the success of the local Lebanese construction projects. It shows the importance of each factor and its role in the attainment of client objectives. A Questionnaire survey, supported by “face to face” interviews, elicit the attitude of owners (developers), consultants, and contractors towards the factors affecting each parameter is done. Conclusion and remarks for future construction quality system rating will follow.

Abstract: Project overheads are allocated on a percentage basis to project costs and common to maintain multiple cost objects, but cannot directly be distributed to construction activities. Construction project overheads have to be identified their cost behaviours properly in order to sustain Cost Management and Controlling Practices (CMCPs) during the construction stage. The literature review method identified forty seven (47)project overheads and categorised into four hierarchies (unit, batch, project, and facility levels). Therefore, the identification of project overheads should enable a sustainable improvement to the CMCPs in construction projects.

Abstract: Over the past few decades, doubts among construction researchers arise about how hospital project success is measured. However, only some general consensus of that matter was agreed upon. Therefore, the aim of this study is to identify the holistic success criteria (SC) of public hospital construction projects. This article describes the criteria, which then conceptually classified the SC into five, which are meeting client requirements; meeting for management of construction goals; meeting for production of construction goals; benefit to the project teams (D&B contractors) developments; and benefiting the community. Every SC describes a set of problem statements as well as dimensions which were based on the following issues: unsatisfactory product quality; prolong of completion period; cost overrun; unsafe site condition; clients’ dissatisfaction; and non-benefit to the community. To realise the objective, questionnaire survey was distributed to the client (Ministry of Health, Malaysia and client’s project manager) and D&B contractors throughout Malaysia. The raw data were analysed using factor analysis (FA) method reduced the variables from 93 items to only 16. Principal components analysis (PCA) procedure considered only the factor loading with a value of 0.500 and above. Each component underwent a process of reliability analysis (RA) with the overall value of Cronbach’s alpha of more than 0.700. Result was found that a set of new measure consisting 16 variables called SC measures were determined. Generally, it covered efficiency of the process and effectiveness of the product. The major limitation of the study was that the key players of the project always changed and most of projects were 95% completed. However, it is important to understand that most of the construction projects are project-basis with temporary organisation. Therefore, extra effort should be emphasised to enhance the quality of the data collected and more research should be done to overcome the issues which still grow concurrent with the development.

Abstract: In this paper, the analysis of the general tendencies of line building of cottage settlement is carried out by houses. The analysis of domestic and foreign development showed that many questions connected with formation of schedules of building of objects of settlement and calculation of parameters of works taking into account restriction on resources at development of local plans of settlement by houses, now finally aren't solved.As practice of construction of settlement shows further improvement of a technique of scheduling of building of settlement by houses has to go on an alternative basis and a choice among them the most effective on economic indicators because of modern computer technologies. The calculation procedure and optimization of options of the line organization of construction of houses because of modern computer technologies is offered.The technique of a technical and economic assessment of optimizing solutions of cottage building is offered. In this paper data on application to the developed technique for scheduling of construction of houses of settlement. The developed techniques can find application when developing projects of the organization of mass building of cottage settlement by houses.

Abstract: In response to this phenomenon that many construction projects failed much earlier than their expected service life ,or failed to accomplish their expected functions caused by the reinforeed conerete structure are found to be suffering from deterioratioon of structural performance and degradation of safety,due to the deficiency of concrete durability. From the perspective of what effect of economic that has been taken by the concrete durability,so the method what would been used to analyze economic of construction project was proposed ,and the objective function of economic analysis of construction project was created based on the concrete durability,all of the above work will lay a solid foundation to study the reliability design of construction project and economic analysis.
