Design-Build Project Performance: Comparison between Commercial Building and Health Care Building Projects

Project delivery planning is a key stage used by the project owner (or project investor) for organizing design, construction, and other operations in a construction project. The main task in this stage is to select an appropriate project delivery method. In order to analyze different factors affecting the PDM selection, this paper establishes a multiagent model mainly to show how project complexity, governance strength, and market environment affect the project owner’s decision on PDM. Experiment results show that project owner usually choose Design-Build method when the project is very complex within a certain range. Besides, this paper points out that Design-Build method will be the prior choice when the potential contractors develop quickly. This paper provides the owners with methods and suggestions in terms of showing how the factors affect PDM selection, and it may improve the project performance.

Method Approach

WBS (Work Breakdown Structure) plays an important role in every construction project. WBS is a hierarchy of decreasing scope of work to become the smallest level called a work package, making it easier in the process of project management and control. The current problem is that many contractors in Indonesia, both large and small contractors, do not understand the importance of using WBS in a construction project. This causes project performance to be less than optimal, especially on cost and time performance. Currently, WBS standards have been developed for building projects. In this study will look at the cost and time performance of the project from the use of WBS standard building. The sample used in this study are projects that have applied the use of project standards. The projects include Building X, Lecture Building Y, and Sports Facility Building Z. The method used in this study is the EVM (Earn Value Method) approach, collecting data using questionnaires. The results showed that using the WBS standard had an effect on cost and time performance. Good cost and time performance is shown in the Building X and Lecture Y buildings. While the cost and time performance of the Z Sports Facility Building tends to be unstable. This is because the work items that exist in the WBS standard are not in accordance with the project conditions, so it is necessary to adjust work items.

Procurement Method

The issue of continual poor project performance in the construction industry remains unresolved and there is need for improvement. In view of improving project performance, the study aims at investigating the frequent causes of errors in construction contract documents. The survey research design and mixed research methods were used for the study. The respondents for the study consist of 86 consulting and 98 contracting firms that have been engaged on building projects that is above one floor between 2012 and 2015. Fifty one (51) interviews were also conducted on contractors, project managers and consultants on the projects they were involved and can equally provide necessary information for the study. Statistical Package for Social Sciences (SPSS 20) was used for the analysis of the study. The study found that the frequent causes of the errors in contract documents are frequent design changes by clients, lack of adequate time to prepare documents and design management experience among others. Based on the findings, it was concluded that the causes of errors in contract documents vary from one state to the other. It was also concluded that there is difference in the causes of errors in contract documents based on types of building, services rendered by construction organisations and states in South West, Nigeria. However, there is no significant difference in the causes of errors in contract documents based on procurement method except where there is incomplete documentation or contracting organisations have overlapping activities. The study recommends that the frequent errors identified should always be prevented from occurring if cost and time overrun are to be minimized. Also since most of the causes identified are related to consultants, it was recommended as suggested by interviewees that all designs must go through quality assurance process.Keywords: Building projects, Construction, Contract documents, Errors, project performance

Purpose Despite the huge capital outlay in tertiary education building projects (TEBP), these projects undoubtedly failed in meeting the set objectives of cost, time and quality, among others. Therefore, rather than the impacts of risks on the overall project performance, which is common in the construction management literature, the purpose of this study is to assess the impacts of risk factors on the criteria for measuring the success of public TEBP. Design/methodology/approach The paper adopted a quantitative research method where the data collection was via a questionnaire survey. The researcher administered 452 questionnaires to the client representatives, consultants and contractors involved in building projects across five public tertiary education institutions in Ondo State, Nigeria. Of 452 questionnaires, 279 were retrieved and suitable for the analysis, translating to a 61.73% response rate. The reliability analysis of the research instrument showed 0.965 and 0.807, via Cronbach’s alpha test, indicating high reliability of the instrument used for data collection. Findings The study found different risk factors affecting the criteria for measuring the success of TEBP. For instance, the environmental risk factor significantly impacted completion to cost, while financial and political risk factors significantly impacted completion to time. In addition, while environmental, legal and management risks significantly impacted end-user satisfaction, safety performance was significantly impacted by logistic, legal, design, construction, political and management risks. Besides, the logistic, legal, design, construction, financial, political and management risk factors impacted profit. However, despite profit being one of the criteria for measuring the success of building projects, it recorded the highest risk impacts amounting to 41% variance. Research limitations/implications The findings are limited to the public tertiary education building projects procured via competitive tendering; therefore, the results might differ when considering other procurement methods. Practical implications The practical implication is that rather than focusing on all risk factors, the project stakeholders could give adequate attention to the significant risk factors impacting each of the parameters for measuring the success of education building projects. Originality/value The study revealed specific risk factors impacting the criteria for measuring the success of TEBP, which extend beyond the use of the overall project performance approach.

PurposeThe Project Management Body of Knowledge recommends the use of issue logs as a best practice to minimize the potential project cost and schedule growth. Although the broader topic of project control has been widely studied in the construction literature, the specific application of issue logs has remained relatively understudied. This study aims to analyze the extent and consistency with which construction teams utilize issue logs and the corresponding project performance outcomes.Design/methodology/approachA dataset of 5,635 individual issues was gathered from the final issue logs of 881 small building projects delivered via the design–bid–build method. Differences between groups were determined using the Kruskal–Wallis H test with post hoc testing via the Mann–Whitney U test with pairwise comparison.FindingsThe results showed that, on average, project teams who used issue logs to a greater extent achieved a 3.1 to 4.3% reduction in cost growth and a 5.3 to 12.3% reduction in schedule growth. This result shows that issue logs can be used to improve construction project performance in the areas of cost and schedule.Originality/valueThis result provides a contribution to practitioners, wherein project teams should be encouraged to establish their issue management practices early in the project schedule to encourage greater issue log usage for the remainder of the project.

Purpose The purpose of this paper is to investigate the effects of implementing value stream mapping (VSM), just in time (JIT), continuous flow and total productive maintenance (TPM) methods throughout production and erection processes of pre-fabricated steel frames (PSFs) of building projects. Design/methodology/approach As phased lean management, after implementing the VSM technique, the JIT technique is implemented as first lean phase and the TPM and the continuous flow techniques are implemented as second lean phase. To evaluate the expected improvement of project performance due to reduce wastes by implementing lean techniques, discrete event simulation (DES) is utilized. In this research, an eight-story residential building project in Tehran, Iran, is studied. Findings Simultaneous use of lean techniques to integrate production and erection processes of PSFs leads to the improvement of the performance of production and erection stages, significantly. The results indicate 43 and 17 percent reduction in PSFs production and erection processes time and cost, respectively. Research limitations/implications In the present study, only the effects of implementing lean techniques on the production and erection of PSFs have been evaluated. However, it is also possible to apply these lean approaches and the key strategies to the other modular or pre-fabricated construction methods. Originality/value The main contribution to knowledge is improving the construction project performance by integrating the production and erection processes, using phased lean management through implementing lean techniques. The results of the current study provide valuable insight into the possibility of integrating and improving construction processes of pre-fabricated construction.
