One of the critical decisions taken by contractors is whether or not to bid for a project. This is due to the complexity and uncertainty surrounding this decision, which is influenced by many factors. Given the above challenge, this study aimed to uncover the critical factors affecting the contractors’ bidding decisions in Saudi Arabia-based construction projects. A questionnaire survey, which consisted of 31 factors, was distributed to first-, second- and third-grade contractors. In total, 67 responses were obtained. Median and relative importance index (RII) techniques were adopted for ranking the most critical factors. Based on the received responses, the top six critical factors were “size of the job”, “type of the job”, “company’s strength in the industry”, “designer/design quality”, “rate of return”, and “project cash flow”. The least significant factors were “job start time” and “labor environment (union/nonunion/cooperative)”. The findings of this study show a level of agreement among all contractors about the critical factors. The findings would benefit contractors and subcontractors by increasing their understanding of the major factors affecting the bidding decision process. Contractors armed with such valuable information will be better able to enhance their bidding decision-making process in terms of efficiency and effectiveness.

Project Delay

This study is conducted to establish the effect of design quality on project delay in building projects. It aims at: 1) investigating the major factors of design quality, 2) identifying the main delay factors in building projects, 2) establishing the relationship between design quality and delay in building projects. To achieve these objectives, a questionnaire survey is performed. Seventeen (17) factors that might affect design quality, and 15 delay factors are listed in a questionnaire form. Sixty (60) contractors and 40 consultants are asked to identify the severity of the identified factors. Results indicate that the top factors affecting design quality are: delay in payments by client for design services, staff allocation for many projects at the same time, copying and modifying from previous work to minimize time and cost, tight design schedule, lack of designer knowledge with techniques and materials available in the market. The study also concludes that the top five delay factors include: payments delay, poor labor productivity, lack of skilled manpower, frequent change orders and rework. Regression analysis for data collected from 36 building projects shows a good correlation between design quality and delay in projects. This study is the first one that addresses the problem of design quality in the West Bank in Palestine. Furthermore, it is the first study that addresses the effect of design quality on project delay in Palestine and the neighboring countries. It is hoped to be helpful for researchers and professionals to understand the impact of design quality on schedule delay.

Productivity is a very important element in the estimation process in construction management. The objective of this research is to identify and analyze the factors which affect labor productivity in construction projects. In this research, 42 effective factors were collected from site survey, interview with engineers and experts, and previous research in the Arab world. These factors are grouped into Nine categories “Workforce, Leadership, Motivation, Supervisors, Safety, Project, Time, Material, and External”. A survey questionnaire of 70 respondents was distributed among different experts. A statistical analysis was done using SPSS and EXCEL packages. The Relative Importance Index was used to find out the most significant factors affecting the labor productivity in construction sites. The results accomplished from the survey revealed that the major factors negatively affect the labor productivity (ranked from the worst factor with Relative Importance Index values, respectively) namely, Availability Material (88.571%), Climate status “Weather” (88%), Religious occasions (86.29%), Number of working groups (86%), Ganger experience (85.714%), Workforce surveillance (84.857%), Ganger Age (84%), working at height (82%), Drawings and specifications alteration during execution (81.69%), and Sequence of floor (80.571%). Based upon these findings, this can help the construction professionals to improve the productivity and project performance in Iraq.

Poor productivity of construction workers is one of the causes of cost and time overruns in construction projects. The productivity of labour is particularly important especially in developing countries, where most of the building construction work is still on manual basis. This paper reports on a survey made on project managers of building projects in Uganda, where an increase in productivity is being sought. Respondents were required to rate using their experience how 36 factors affect productivity with respect to time, cost and quality. The survey was carried out by a questionnaire and responses received over a period of 3 months. The ten most significant problems affecting labour productivity were identified as incompetent supervisors; lack of skills from the workers; rework; lack of tools/equipment; poor construction methods; poor communication; inaccurate drawings; stoppages because of work being rejected by consultants; political insecurity; tools/equipment breakdown; and harsh weather conditions. Although lack of materials is ranked highest with regard to average rating on loss of time, it was not ranked among the top ten using the importance index that takes into account time, cost as well as work quality. The policy makers and researchers should focus on the identified major factors in order to improve productivity.

The Cost

Public construction projects in Saudi Arabia have been suffering from low performance for the past decade. Cost overrun is one of the most important issues in project’s performance and is nearly associated with most of public projects. The aim of this study is to identify and assess the major factors leading to cost overruns in education construction projects in the Northern Province of Saudi Arabia to minimize the risks’ effects in future projects. The research methodology started by identifying cost overrun factors through literature review, project’s documentations, and experts’ interviews. Professionals who worked at the construction projects undertook a questionnaire survey to investigate the importance of the cost overrun factors. The top factors of cost overrun were identified through the analysis of the factors’ occurrence and severity. The study main results included the top causes of cost overrun which are delay in contractors’ progress payment by client, difficulties in financing project by contractor, delays in sub-contractor’s work, additions of quantities such as excavation, backfill, and concrete works, and bid award for lowest price. The investigated risks in the study should be evaluated and mitigated in future projects to minimize their effects and enhance the industry performance.

The Impact

Cost overrun in construction projects is a common phenomenon in Iraq. This might occur due to diversity of factors. This study aims to identify the factors influencing construction projects cost that are potentially controllable by main contractors. A field study through a questionnaire survey was directed to a sample of related Iraqi professional engineers from general contracting companies at both public and private sectors. Their opinions on the impact and frequency of each factor were investigated. The questionnaire offered (59) factors classified in (8) categories namely; legislations, financial and economic, design, contractual, site management, material, labor and equipment. The factors were ranked according to the highest Relative Importance Index (RII). The study revealed (10) major factors that are potentially controllable by main contractors namely; labor productivity, sub-contractors and suppliers performance, equipment productivity, site organization and distribution of equipment, experience and training of project managers, scheduling and control techniques, planning for materials supply, planning for equipment supply, materials delivery and planning for skilled labor recruitment. Recommendations to aid contractors and owners in early identification of these factors are also included in this study.

Purpose The purpose of this paper is to develop a motivation framework that will enhance labour productivity for Iskandar Malaysia (IM) construction projects. The vision of IM development corridor is to become Southern Peninsular Malaysia’s most developed region by the year 2025. IM cannot realise this foresight without effective labour productivity. Previous studies have reported that the labour productivity of IM construction projects was six times lower than the labour productivity of Singapore construction projects, due to lack of motivation among IM labourers, and a shortage of local skilled labour. Therefore, there is a need to study how to motivate IM construction labourers, so as to increase their productivity. Design/methodology/approach A quantitative research method was used to collect data from IM construction skilled labourers and construction professionals, using two sets of questionnaire. The respondents were selected using a purposive sampling technique. In total, 40 skilled labourers and 50 construction professionals responded to the questionnaire survey, and the data were analysed using Statistical Package for Social Science software (version 22). Findings The analysis revealed the major factors that motivate labourers participating in IM construction projects. The factors were ranked hierarchically using Relative Importance Index (RII) and the outcome of the ranking indicated that effective management, viable construction practices, financial incentives, continuous training and development, and safe working environment were the most significant motivation strategies that positively influence IM construction labourers. Originality/value The study developed and validated a framework that can be used to boost the morale of IM construction labourers, so that their productivity can be increased. Implementation of the established motivation framework will also lead to career progression of IM construction labourers, based on the training elements in the framework. This career prospect will attract local skilled labourers to participate in IM construction projects.

The study objective was “An assessment of critical factors affecting quality performance of government financed construction projects in Tanzania”. The study was initiated as much of government financed construction projects are executed with variations on delivering time, cost and quality. The study identified factors if not considered can lead to poor quality performance of projects. Closed end questionnaire consisting of 20 performance factors were issued to 80 respondents dealing with construction related activities, they were required to rank them on a 5 point Likert scale. Data analysis was done using Statistical Package for Social Sciences version 16 (SPSS). The findings revealed that the critical factors that have direct impact on quality performance of government financed construction projects are; project financing processes, experience of contractors in construction industry, project technology, availability of plant and equipment, procurement system and processes as well as the project manager knowledge and skills. A multiple regression model developed showed a positive linear relationship between project quality performance and the critical quality performance factors. All the critical quality performance factors had positive coefficients with an acceptable level of significance. The study recommends further studies on the economic and social factors that hinder women participation in construction relation activities and how training and learning opportunities for continuous improvement will have positive impact on the performance of construction projects.
