Level Of Risk

The importance level of risk throughout the construction progress is apparently inherit tendermous impact on the ultimate project performance and client satisfaction. Such determination level of risk in terms of frequency, time risk as well as cost effect to be perceived from two perspectives, owner and contractor, is inventably crucial to be researched, primarily for housing construction in Surabaya. This study was conducted by applying a survey through some questionnaires to observe 30 risks that have been identified from the previous literature. Total respondents involved were 69 respondents consisting of 29 respondents representing the owner / developer and 40 respondents representing the contractor. The results of this research, as from owners’ perspective, shows bad weather was the most common risk, followed by contractors’ financial difficulties which has the utmost impact on time and increasing material price takes major part on costs respectively. Whereas according to the contractor, design changes from consultants / owners are the most frequent risks, design changes from consultants / owners have prominent impact on time and lastly worker productivity also siginificantly reinforces expense factor.

Factors Affecting Performance

Construction time and cost are basic parameters for measuring project performance. Unfortunately, construction projects are facing poor time and cost performance globally. This poor performance is occurred due to several factors among which resource related factors play very important role. Hence, it is very essential to control the factors affecting performance of time and cost. This study assessed significance level of the resource related factors and determined effective measure to mitigate the factors. Gathering of data was done by questionnaire survey with the practitioners representing client, consultant and contractors involved in handling execution works. Statistical analysis of gathered responses revealed that High cost of machinery and its maintenance; and fluctuation of prices of materials on site are significant resource related factors affecting project cost performance while in affecting time performance, the significant factors are financial difficulties faced by contractors and high cost of machinery and its maintenance. This study also assessed the effectiveness level of the mitigation measures for improving time and cost performance. The findings of this study will be helpful for the practitioners to make necessary arrangement for improving time and cost performance.

The construction industry is facing numerous difficulties in managing construction waste, quality, environment, permanence, safety, and greater construction cost. Dynamic change is needed today to overcome new challenges in the construction industry. Adoption of prefabrication is one of the possible solutions to such problems. This paper explores the advantages in prefabrication adoption with its possible disadvantages (barriers) through the qualitative study. This paper is an addition to the existing literature of prefabrication specially for developing countries where the acceptance rate of new approaches is difficult. It covers private residential project and a public housing project. This study also aims to evaluate the current status of prefabrication adoption in small-scale construction projects. A set of the questionnaire is used to collect the data and Average Index (AI) method using SPSS has been used to analyze the results. Shorter construction time, Low site waste and better supervision are the main advantages. Higher initial construction cost and Strict & difficult design changes are the key disadvantages. It is analyzed that the conventional construction method is more frequently used when compared with prefabrication concept.

Time overrun is a major issue in construction projects. Its causes vary, depending upon the nature and size of the project. Developing countries are more susceptible to this problem due to limited resources and lack of managerial skills. This paper focuses on the identification and classification of time overrun factors in public sector projects in Pakistan. Data was collected by the use of a questionnaire given to different professionals in the construction field. Average index (AI) was used to determine each factor’s relative importance. Results indicate that financial difficulties faced by constructor, inadequate planning and scheduling, financial difficulties faced by client, delays in payment by the client, delays in decision making by the client, design mistakes, frequent design changes, material shortage, incompetent sub-constructor assigned by the constructor, poor site management and supervision and inadequate constructor’s experience are the most significant factors of time overrun in public sector construction projects in Pakistan. This study aims to be useful in addressing the issue of time overrun in the construction industry.

This paper provides a literature review assessing the performance and issues of delivering construction services in the Vietnam Construction Industry (VCI). The research also explores a potential solution that could improve the performance of the VCI. The results show multiple non-performance issues that the VCI has experienced in the past 15 years, and presents a comparison between these issues and issues from other countries. The results reveal that the top 5 non-performance issues in the VCI include poor design services, frequent design changes, lack of skilled contractors, a lack of experienced project managers, and financial difficulties of owners. The comparison identifies that 87% of VCI issues were also experienced in other countries. Since the VCI has similar issues as other countries, the author propose that the VCI can improve construction performance by implementing successful methodologies from other countries. This paper investigates the Best Value Performance Information Procurement System (BV PIPS) as a potential solution because of two key aspects: (1) sufficient documentation of on time, on budget, and high customer satisfaction from this model, and (2) sufficient testing from other regions and countries to show similar improvement in construction performance.

Purpose Projects often face delays and unnecessary use of time due to various factors and reasons, and hence suffer from unfavourable consequences. The purpose of this paper is to identify the universal delay factors from an intensive literature review, complemented by delay factors in major Norwegian construction projects based on empirical data. Design/methodology/approach The study in which this paper is based includes an intensive literature review, and semi-quantitative open survey questionnaires. This paper addresses frequency and type of delay factors in construction projects, in Norway based on the survey, and worldwide based on the previous studies. Findings From the study, the causes of delays facing the Norwegian construction industry are: poor planning and scheduling; slow/poor decision-making process; internal administrative procedures and bureaucracy within project organisations; resources shortage (human resources, machinery, equipment); poor communication and coordination between parties; slow quality inspection process of the completed work; design changes during construction/change orders; sponsor/owner/client lack of commitment and/or clear demands (goals and objectives); late/slow/incomplete/improper design; office issues; and users’ issues. And the top 10 universal delay factors are: design changes during construction/change orders; delays in payment of contractor(s); poor planning and scheduling; poor site management and supervision; incomplete or improper design; inadequate contractor experience/building methods and approaches; contractor’s financial difficulties; sponsor/owner/client’s financial difficulties; resources shortage (human resources, machinery, equipment); and poor labour productivity and shortage of skills. Research limitations/implications When it comes to the identification of delay factors in major Norwegian projects, the research is based on a sample of 202 respondents from an open survey questionnaire. It should be noted that analysing a large population of respondents that have been asked open questions can be challenging due to the vague findings it might lead to. Also, when it comes to the identification of the universal delay factors, there were different methods used by different authors, within different context. Similar future studies in Norway based on qualitative and quantitative methods will give better verification for the findings. Practical implications This paper has documented the critical delay factors/causes in Norway. The results of this study will help project managers, in Norway and elsewhere, to be aware and know about the potential causes of delay in their construction projects, which will help to identify the possible risks in the early phases of the project. Another practical implication is to make project managers and policy makers conscious that delays are quite universal, making it necessary to identify them as a first step. Social implications The identification of delays factors and causes can permit projects to implement mitigation actions to avoid delays, thus allowing delivering schools, hospitals and other necessary infrastructure on schedule or ahead of schedule to society. Originality/value This paper highlights most (almost all) of the studies in the literature, including to the study done in Norway, concerning the delay factors in construction projects and large construction projects in general. This wide review of relevant literature will save time other academicians from having to conduct similar studies. This study will assist both academic and professional experts providing more insight about the delay causes in large-scale construction projects.

Design changes in construction projects are always going to happen and cannot be avoided. Design changes are the primary contributor to disruption of time and cost performance of construction projects. Previous research in this domain lacks of detail studies on systematic review on the existing literature. This paper reviewed literature published in peer-reviewed journals and conference proceedings in the construction management field and had emailed several questions to the expert in construction industry. The objectives were to recognize the causes and impacts of design changes on project performance and to provide insights for future studies in Malaysian context. The findings indicate that design changes originate mainly from the owner side are identified as important causing factors to time overruns and cost overruns. This paper proposes framework for the management of design changes in construction projects.

Cost performance is one of the basic criteria for measuring construction project success. Despite its proven importance it is not uncommon to see a construction project failing to achieve its objectives within the specified cost. The paper attempts to identify the major causes of cost overrun in Bahrain construction sector, and to assess the effect of these causes on cost overrun.  A list of these causes was collected through an extensive literature review, historical construction projects records and expert opinions. In total 45 factors were short-listed to be made part of questionnaire used in a survey conducted with representatives from local contracting, consulting, and client firms. Findings are presented in form of tables that classify cost overrun factors, and their ranking. The overall results showed that frequent design changes, mistakes during construction, and schedule delay were considered as the most important factors of cost overrun causes in Bahrain construction industry.
