Pre-planning of construction projects is important for the performance of cost, time, and quality. However, recent research finds that quality related to final testing, adjustment, and balancing of HVAC systems are often overlooked due to deadline pressure. Consequently, this results in poor energy performance and dissatisfied end-users. The purpose of this study is to investigate the relationship between pre-planning, commissioning, and project performance. A publicly funded project with a compressed construction period was followed as a case study. During the case study, passive observation, semi-constructed interviews, and questionnaires were applied. This study showed that by implementing commissioning, project pre-planning and organizational support is increased. Moreover, the commissioning process creates awareness and fosters proactivity between the project participants, thus complications are discovered and handled earlier. By improved pre-planning and organizational support, and increasing proactivity, the project’s cost, time and quality performance is improved. This underlines the importance of prioritizing pre-planning. Moreover, increased energy and technical demands increase project complexity which makes project success even more dependent on the quality of the plans.

Construction projects are of very complex nature, and subject to circumstances of high uncertainties and risks due to the interdependences of activities and processes in the project performance.  As a result of the dynamic complexities inherited in construction projects, changes in the scope of work are inevitable. Of particular concern is that, when scope changes are introduced in a project, contractors follow a systematic procedure in managing the changes, but with poor planning and implementation thereof because the project complexities that underpin the scope changes are not fully understood. Therefore, despite that complexity is an inherent and defining feature of construction projects, studies in the literature have failed to grasp and present the dynamics of project complexity which underlie the scope changes in the delivery of construction project. The TOE (Technical Organizational Environmental) framework was adopted and applied on a multiple-case study research design in order to explore and denote project complexity relations to scope changes in construction projects. Through a content analysis procedure, six key elements of project complexities that relate to scope changes in the construction projects has emerged. Understanding these complexity elements could enable the project management team to apply a front-end planning approach in the initiation phase of the projects in order to better manage scope changes in the execution phase of the project, and eventually to improve the project performance.

Risk Management is recognized as an important exercise that creates value to a project and improves project performance. Time, cost and quality are the primary measures of a project performance in this industry. The success or failure in any construction project can be monitored through the attainment of these primary measures. Notably, Malaysian construction industry is considered as one of the important industries that positively contribute to the increase of Gross Domestic Product and subsequently the growth of the country’s economic development. Unfortunately, this industry suffers poor performance in which it leads to failure in accomplishing effective time, cost and quality performance. Most construction projects face a schedule delay, cost overrun and are poor in product quality. Thus, the aim of this study is to determine the influence of risk management on construction project performance of Malaysian companies based on these three primary measures. The degree of diffusion of risk management practice in the chosen construction project in Malaysia is also examined. The methodological approach exploited in this study is a case study approach involving analysis of documented data and face-to-face interviews with key players that hold different roles and responsibilities. They include a director, project managers, finance managers, contract managers and quantity surveyor managers. The results demonstrate that adopting effective risk management practices positively impacts project performance thus leading to project success. Nevertheless, the lack of knowledge and poor communication of risk management practices in construction projects contribute to the weak implementation of an effective and systematic risk management practices in Malaysia.

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.

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.

One of the most controversial issues in construction management is performance measurement. Construction managers are always involved in evaluation of resource changes which effect process performance. Due to limitations and also cost of resources, resource allocation has become a complex task in construction projects. To evaluate the effects of different resources on total project performance, managers strive to allocate limited resources by determining resource combinations. This paper aims at conducting Taguchi method along with computer simulation to determine the optimum combination of resources for a real world case study involving a concrete pouring operation in order to reduce cycle time and process costs. The proposed simulation model was conducted under Arena 13.9. Final result shows that the optimum resource combination will be achieved when all of resources are located in the low level. This means that number of trucks, spreader crew, vibrator crew and finisher crew should be equal to 3, 1, 1, and 1 respectively to improve the total performance.

The purpose of this study is to avoid delays and cost changes that occur in emergency reconstruction projects especially in post disaster circumstances. This study is aimed to identify the factors that affect the real construction period and the real cost of a project against the estimated period of construction and the estimated cost of the project. The case study is related to the construction projects in Iraq. Thirty projects in different areas of construction in Iraq were selected as a sample for this study. Project participants from the projects authorities provided data about the projects through a data collection distributed survey made by the authors. Mathematical data analysis was used to construct a model to predict change in time and cost of the projects before the start of the construction. The artificial neural networks analysis was selected as a mathematical approach. The most important factors identified leading to schedule delays and cost increase were contractor failure, redesigning of designs/plans and change orders, security issues, selection of low-price bids, weather factors, and owner failures. The use of the ANN model for such a problem is expected to be an effective method for modeling this complicated phenomenon.

Public projects in Saudi Arabia have been experiencing low construction project performance for the past decade. Studies have identified the low-bid delivery method as an important factor in causing such delays. In addition, low bids for contracts have not reflected the actual project cost. A case study was conducted at a university campus in northern Saudi Arabia in which the actual project costs for four projects were examined. The study found that all four projects’ costs were higher than the original bid. In addition, a large survey was conducted of 804 classified contractors and universities representatives who identified change orders as the most common factor causing cost overruns in Saudi Arabia. Previous studies showed that some contractors aim to submit low bids for winning the competition then change orders to reduce their losses. Consequently, low bids also lead to cost overruns. In a comparison using the result of a case study and the results of the Performance Information Procurement System (PIPS), Saudi Arabia’s delivery system was identified as a potential cause of project performance issues.
