Assessing construction project performance through adapting an innovative approach can multiply the production of high-quality project outputs which is a catalyst to the socio-economic progress of a country. Preliminary data collection was employed through a meta-cognitive analysis of reviewing related literature which directs to the backbone of qualitative information that is relevant to the periodically experienced construction performance-influencing factors and to develop an assessment questionnaire about the influencing factors affecting the project performance. The IBM SPSS program was used to verify the reliability and consistency of the fundamental statistics of the questionnaire responses of cost, time and quality performance ratings. A predictive mathematical model was developed for forecasting cost, time, and quality performance rating employing Levenberg-Marquardt training algorithm with Hyperbolic Tangent Sigmoid function. The prediction model result shows a highly satisfying performance on its variance from the substantive values and suggests a high correlation between these values. The relative importance of the factors affecting the cost, time, and quality performance rating was calculated via sensitivity analysis through connection weights using Garson’s Algorithm to view the order of influence of the parameters that have great significance to the success of a project.

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.

Construction projects in all regions continues to be developed for the creation of facilities that can be utilized by the community. One of them is the construction of apartments which are now being intensively carried out to meet residential needs for the community. Making a construction project plan always refers to estimates that exist at the time development plan is made, therefore problems can arise if there is a discrepancy between the plans that have been made and the actual reality. So the impact that often occurs is the delay in the time of project implementation which can also be accompanied by an increase in the cost of implementing the project. In the construction project of Cinere Terrace Suites Apartemen & Citywalk, Jakarta there was a delay resulting in a late payment of monthly bill progress by the owner. Based on the above reasons, this research was conducted to find out how the project performance was seen from the cost and time period of the review period. how is the estimated cost and time to complete the overall project work. The method used in the analysis of this study is the Earned Value Method. Based on the results of the analysis carried out for 29 weeks the project performance on schedule has been delayed and cost shows a positive value. For the estimated completion time of the project there is an increase in time whose duration increases from the planned 98 weeks or 685 days to 109,624 weeks or 768 days. While the estimated cost of completing the project from the results of the analysis obtained a value of Rp. 270,147,448,569.16 smaller than the planned cost of Rp. 315,272,727,272.73. With the difference VAC of Rp. 45,125,278,703.57 this shows that there are benefits obtained by the contractor.

PurposeIt is well recognized that the construction industry is characterised by inefficient and ineffective service delivery due to various causative factors. Thus this study aims to examine the influential factors affecting public construction project performance in Ethiopia to improve the industry's service delivery.Design/methodology/approachFrom the extensive literature reviewed, 58 potential factors affecting construction project performance have been compiled. Based on the evidence accumulated, the conceptual model of this paper has been developed. By using survey questionnaires, valuable data were collected from the construction industry professionals in Ethiopia; analysed and interpreted with the use of both SPSS and AMOS software.FindingsIt is concluded that failure factors related to the “performance” of the contractor, the “capability” of the owner, the “project design-procurement process,” and project contract management can significantly contribute to the poor performance of public construction projects in Ethiopia. Ten key factors include inadequate contractor capacity, weak project site management and supervision, weak project management skills and capabilities of the owner, additional work orders, delayed payment, lack of comprehensive project plans between parties and incomplete project design, rising material prices, ineffective project schedules, and cost management, rising market prices and devaluation of the currency.Research limitations/implicationsThe scope of this study confined to public projects in Ethiopia. It suggests that further research needs to consider public and private construction from a comprehensive perspective in the developing countries.Practical implicationsIt provides practitioners with information and guidance on the factors that affect the performance of construction projects.Originality/valueIt provides inclusive evidence related to many factors that affect the performance of public construction projects.

Abstract The Indian construction industry has the cognitive frame of operating in the cost-based approach rather than the value-based approach, and the project process and strategies are framed in such a manner to increase the profitability of the project by the organization. Nevertheless, the profitability margin of the construction project is very comparatively low compared to the other Industrial sectors. There is much reason for not attaining a higher profitability margin in the construction sector. Some of the reasons are the low innovative business plan, ineffective data-driven decision-making, ineffective management of the transaction, and construction risks.The responsibilities of increasing profitability and managing the transactional flow in the project are given to the commercial manager. The roles and responsibilities of the commercial manager vary globally. The quantity surveyor's job role further enhanced the commercial manager, where the latter can take the commercial decisions about the project.This research paper's primary outcome is the framework model for making effective decisions by the commercial manager, which increases the project's profitability. The systematic decisions, which are made in the projects by the commercial manager are studied. Considering the external factors like the COVID-19 outbreak, market condition, and existing factors affecting the decision-making process, the tools and techniques for making efficient decisions in the construction project are suggested. The synergies between these tools and techniques are studied, and a decision-making model is framed to reduce the cost and time overrun, and the benefits associated with implementing the model in the project are detailed.

The Cost

The development of road infrastructure is closely related to national competitiveness and presents significant socioeconomic impacts. However, road construction involves a large budget and is vulnerable to political, economic, social, and project-specific risks, which often result in cost overruns and schedule delays. Assessing the gap between the final performance and the planned performance, and providing feedback to similar projects in the future is essential for successful project planning and management. The aim of this study is to empirically analyze the cost and schedule growth of road construction projects, considering project characteristics. Using the national-level project performance data, the primary goal is to answer, “Do project characteristics influence the road project performance? If so, how different is the performance because of the project characteristics?” To this end, this study analyzes the cost and schedule growth of 423 road construction projects, considering five project characteristics: facility type, construction type, bid type, contract type, and project size. Non-parametric tests (the Mann–Whitney U test and the Kruskal–Wallis test) are used to analyze the differences between sample groups. The results demonstrate (1) better management of the performance of the highway when compared to the national and provincial roads; (2) higher schedule growth of the expansion and renovation than that of the new construction; (3) lower cost growth of the design-build method (turnkey and alternative) than the design-bid-build methods (qualification examination and lowest price); and (4) relatively larger cost and schedule growth for projects over $50 million than those of smaller projects. These results present empirical references from the Korean construction industry that can help construction-related entities (clients, design consultants, and contractors) to estimate and manage the cost and schedule buffers of future projects by considering different project characteristics. Discussions and suggestions connected with the findings are also provided. Future research will continue to shed light on the critical factors affecting the cost and schedule growth.

Globally construction works are suffering from several challenges. One of the major challenges is changes during execution of the construction work. Changes exert several negative impacts on the project performance. For effective project performance, it is necessary to understand the effects of changes. Hence, this study investigated various effects of changes occurring in construction project. Investigation was carried out quantitatively through questionnaire survey based on effect variables identified from review of literature. It involved three categories as time overrun, cost overrun and quality measured with 48 variables. 100 questionnaire sets collected against 218 questionnaire forms distributed among the practitioners were analysed statistically. From analysis results, it was found that cost overrun is major effect of changes followed by quality and time overrun. Delay in completion schedule, slower project progress and dispute between owner and contractor are reported as major drivers of time overrun. Top three variables of cost overrun in cost overrun are increase the cost of the projects, interrupted cash flow and additional money for contractor. While, major drivers of the quality in construction projects are rework of bad quality performance, changes in materials specifications and changes in material types & specifications during construction. These findings will be helpful for the practitioners in achieving project performance.

Purpose A construction project traditionally involves a variety of participants. Owners, consultants, and contractors all have diverse opinions and interests, but they all seek to ensure project success. Success is habitually measured as performance output regarding cost, time, and quality. Despite previous research mapping the success and failure factors, construction managers seem to have difficulty in attaining success. To provide clearer guidance on how to fulfill success criteria, the purpose of this paper is to identify the underlying factors that affect performance and thus project success in construction processes. Design/methodology/approach A questionnaire survey based on a literature review provided 25 key process factors divided into five key categories. Based on the responses from commonly involved construction parties, the factors were ranked and tested for significant differences between the parties. Findings The top five most important process factors were found to relate to the sharing of knowledge and communication. Moreover, testing the ranking for significant differences between owners, consultants, and contractors revealed five differences. The differences related to the interpretation and importance of trust, shared objectives, project coordination, and alternative forms of coordination. Originality/value All respondents identify improved knowledge sharing and communication as the key to improved cost, time, and quality performance and are therefore the areas where construction managers need to focus their resources. Thus, improved experience sharing and communication will increase the likelihood of project success, through improving competences, commitment, and coordination.

The Cost

Actual cost in construction projects has tended to exceed the project budgets. Thus, cost contingency from the initial of the project is the significant budget to complete project activities. Cost contingency is an important element of  cost estimation to protect project stakeholders such as owners, contractors, and architects from the risks of the project. This paper reviewed the previous studies to find the factors affecting cost contingency and proposed a regression model to predict the cost contingency for private projects in Vietnam. Through industry survey, project performance information from a total of 48 private projects in Vietnam was gathered. The research also compared with other studies to have an overview about cost contingency predicting methods. The key benefit of this research is that the project managers can use this model as another forecasting method to get a better quality cost management. The further research can be focused on developing the model for other project types in Vietnam.

Activity related to structural concrete work is still often found the opportunity of quality deviation from implementation factor and supervision factor, especially if the requirement of the concrete volume of structure every day is big enough. With the above background, the researcher conducted the observation with the core study on ”The Role of Related Party Project on Quality Control (Concrete Structure) and Project Performance Achievement”. That is related to the quality control of concrete in the implementation of construction work and studies that focus on the assessment of achievement of construction project performance. For data analysis (data processing) that is qualitative data and quantitative data, researchers use help the method of Stepwise Regression. The result of this research is very positive influence of Concrete Quality Control factors and the role of project related party influence to the achievement of Construction Project Performance, that is proved by stepwise regression test and hypothesis test, where Quality Performance (Fi = 21,758 > Ft = 2,060), Time Performance (Fi = 14,950 > Ft = 4,496), Cost Performance (Fi = 15,379 > Ft = 4,496). For Quality Performance is shown : coefficient of determination or R square = 0,876, influencing variable is implementation aspect (x1), and aspects of human resources (x2), with Y1 = 0,285 + 0,148.x1 + 0,071.x2. Related to Time Performance : coefficient of determination or R square = 0.537, the variable that influences is monitoring time schedule (x1), with Y2 = 2,166 + 0,415.x1. Related to Cost Performance : coefficient of determination or R square = 0.481, the influencing variable is the acceleration of implementation (x1), with Y3 = -0.741 + 0.958.x1. So If the project organizers feel that these variables have been fulfilled, then the performance of the resulting construction project will be better too.Keywords :Stepwise Regression, Concrete Quality Control, Construction Project Performance, Quality Performance.
