Quality Control of Water Conservancy Construction Projects Considering Contractor's Credibility

Nie, X.T.; Wang, Y.H., and Wang, B., 2020. Quality control of water conservancy construction projects considering contractor's credibility. In: Guido Aldana, P.A. and Kantamaneni, K. (eds.), Advances in Water Resources, Coastal Management, and Marine Science Technology. Journal of Coastal Research, Special Issue No. 104, pp. 410–414. Coconut Creek (Florida), ISSN 0749-0208.This paper studies the decision-making on quality supervision and the issue of retaining quality margin of the owner in different situations of available information within a construction supply chain composed of both the owner and the contractor of water conservancy projects. Based on the influence of the credibility level of the contractor in varying situations of information availability and by drawing from the principle of maximum value as well as the game theory, we have analyzed the relationship among the level of quality supervision, the amount of retained quality margin, and the quality credibility level with different information. Through our analysis, we aim to help owners avoid moral hazards by contractors as well as the latent risks and potential losses. The study helps to improve the quality supervision by owners and achieve the win-win outcomes for both owners and contractors.

Management and Cost Control of Construction Projects in Jordan

The variations in time and quality are vital to the projects' success. Though the cost variation is the most impacting variation, the objective of this study is to recognise the significance of the cost controls in the construction projects in Jordan. Moreover, it aims to determine the factors that lead to reduce these costs. For the methodology, the study used the questionnaire instrument for the data collection. The study sample entailed 154 respondents who hold the responsibility in relevance positions with experiences in contracting and consultants engineering field in Jordan under first and second-grade classification. The study results revealed that there is a significant relationship between cost reduction and all investigated factors, namely, the demographic variables, the pre-execution conditions and specification, and managerial, technical, or financial dimensions. Further, the results showed a significant impact of proper resource planning. In summary, the key factors affecting the project cost during the pre-execution stage involves the appropriate resources planning (i.e., workforce, funds, data). In details, the most critical factors affecting the project cost from managerial dimension are the project manager assignment and integrity of consultant. For the technical dimension, the elements are the skilled workers, the applied methods, the statements and specifications. Lastly, for the fund allocation dimension, the most critical factors that affect the project cost from a financial point of view. Lastly, a set of recommendations are proposed to the project managers to reduce the cost.

Strengths and shortcomings of methodologies for production planning and control of construction projects: a systematic literature review and future perspectives

Several methodologies for production planning and control have been introduced over the years in the construction industry. However, in this industry, it is not uncommon that projects are delayed and go over the assigned budget. In this study, we performed a Systematic Literature Review to investigate the strengths and shortcomings of methodologies used for production planning and control on-site. To consider all of the main aspects of the execution process, we studied activity, location and object-based methodologies. As main findings it emerged that the analysed methodologies are difficult to apply in practice and that they support in a limited way the assessment in real-time of the construction progress and project status, the early identification of problems as well as recovering actions. To support practitioners in deciding about one or another methodology, or to build on a hybrid one, the paper proposes a classification of strengths and shortcomings from a project planning, scheduling and monitoring perspective.

Extending BIM Interoperability for Real-Time Concrete Formwork Process Monitoring

The concrete formwork process is a critical component of construction project control because failing to gain the necessary concrete strength can lead to reworks and, consequently, project delays and cost overruns during the project’s execution. The goal of this study is to develop a novel method of monitoring the maturity of concrete and providing reduced formwork removal time with the strength ensured in real-time. This method addresses the wireless sensors and building information modeling (BIM) needed to help project management personnel monitor the concrete’s status and efficiently decide on the appropriate formwork removal timing. Previous studies have focused only on the monitoring of concrete’s status using sensor data or planning the formwork layout by integrating the BIM environment into the design process. This study contributes to extending BIM’s interoperability for monitoring concrete’s maturity in real-time during construction, as well as determining the formwork removal time for project control. A case study was conducted at a building construction project to validate the developed framework. It was concluded that BIM can interoperate with the data collected from sensors embedded in concrete, and that this system can reduce formwork removal time while retaining sufficient strength in the concrete, rather than adhering to the removal time given in building code standards.

Control of construction projects using the Earned Value Method - case study

Abstract Planning, controlling, monitoring progress are key management functions for effective implementation of construction projects. Commonly used instruments enabling performance of these functions include schedules and budgets, often in the form of a cost estimate. They are created at the initial planning stage to monitor and control cost and time deviations. Moreover, popular monitoring techniques are, for example, observation of milestones and comparative analysis of actual versus planned costs. This article presents a work progress control tool - the Earned Value Method (EVM) - which, despite its benefits, remains relatively unused in construction projects. The impact of the planning phase on the results obtained during the monitoring and control phase when utilizing EVM is discussed. This case study provides practical examples of using EVM in the implementation of construction projects and with the use of computer software. The novelty of the article results from the introduction of additional sensitivity analysis illustrating the impact of factors, such as an increase in costs or a change in delivery dates to the course of deviation curves. Use of sensitivity analysis in relation to the results of the CPI and SPI calculations affords combining control of costs and time with risk monitoring in the project. The findings reveal significant benefits in using EVM to implement construction projects but also highlight some important limitations.

Automatic point cloud coarse registration using geometric keypoint descriptors for indoor scenes

Abstract Laser scanner is a powerful tool which helps in the control of as-built construction projects. The automatic registration of the acquired point clouds without the use of artificial targets is a relevant subject in current investigation. This work focuses on extracting descriptive keypoints from geometric point descriptors, in such a way that keypoints are suitable to perform 4 Points Congruent Sets coarse registration without artificial targets. These keypoints are obtained via 3D Difference of Gaussians over geometric scalar values of the points resulting in characteristic salient features. The registration procedure reduced the RMSE around 2 cm during coarse registration comparing against state of the art algorithms. These RMSE values allow the subsequence use of fine registration via ICP completing the automation of the registration process. Geometric keypoints are demonstrated to be a suitable way to obtain automatic point cloud registration and open the way to future developments.
