Material cost is almost 50-60% of most construction projects. A better material management contributes to lesser cost for a project and also, sustainable use of available resources in the long run. This project aims to identify the major factors affecting material management in a construction project. The various factors at different stages of material management are identified and put in a form of a questionnaire. The responses to the questionnaire were obtained from the stakeholders such as architect, storekeepers, material managers, quantity surveyors, site engineers, project managers, and project engineers. The relative importance of each factor is arrived at based on the ranked response obtained from questionnaire survey. Among the factors identified, the factor ‘unclear definition of roles and responsibilities’ is ranked as the major factor that affects material management

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.

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.

Quality management is considered one of the most important obstacles facing the construction industry in Sudan. The application of a quality assessment system contributes to the development of quality in projects as it is possible to measure the quality in projects. This paper aims to introduce one of the quality assessment systems, which is the system followed and applied in the Singapore (CONQUAS). This system assesses quality based on structural, architectural, mechanical and electrical work. The paper also aims to study the factors affecting the application of the quality assessment system in Sudan. The study is carried out in the region of Khartoum. The study is focusing on the construction projects. The study is carried out by questionnaires and other literature review. The respondents are consultants and contractors. The data has been distributed and analyzed by using the Average Index. From the study it was found that CONQUAS standard is assessed the building based on workmanship standards by the assessors from the BCA on site using standard score sheets. The assessment is done throughout the construction process for structural, mechanical and electrical works, and from questionnaire results the main factors affect construction industry in Sudan is lack of standardization in Sudan. The author recommended that more study shall be conducted to identify factors affecting quality in Sudanese construction industry and how to improve the quality.

An exhaustive literature search revealed that not much research has been done on factors causing problems in managing a construction project in a country under military occupation like Palestine. So, it is the main goal of this research is to identify these factors which could be used by the decision makers to select the appropriate project manager who bosses the suitable skills and competencies to deal with these problems. The study is a step toward determining means to improve the effectiveness of projects through identifying project manager competencies. It is important for Palestinian construction industry to progress in terms of project success; the problems that face the project managers must be determined and identified, in order to achieve the best results with less risk. A clear understanding of such problems helps the Palestinian construction industry of finding the suitable solutions to overcome these problems. A questionnaire survey was carried out to achieve the main aim of this research. The respondents were engineers have more than 3 years in the position of project manager in the Palestinian construction industry. The survey was based on factors drawn from findings of another researches in different countries, together with special factors identified as potentially affecting Palestine. The results identified many factors created problems; they were clustered in eight groups. These groups were arranged according to respondents in descending order as follows: the political situation of Palestine, lack of consultants` technical competencies, lack of resources, insufficient planning, team members uncommitted, conflicts between departments, breakdowns in communications, and changes in goals. As a result of this study one could conclude that managing a project in Palestine is as difficult as the complication of the political situation of the country. The project manager should have a complicated mixture of skills and competencies from dealing with Israeli occupation to dealing with stakeholders to lack of resources and unclear goals. The study has recommended to the Palestinian government to improve the regulations and laws to meet the impact of closure and segmentation of the Palestine.

Perubahan dalam pembinaan telah lama menjadi isu pertikaian antara pelbagai pihak yang terlibat dalam projek pembinaan. Namun, hanya sejumlah kecil kajian yang rasmi telah dijalankan untuk menganalisis sebab-sebab dan kesan-kesannya. Kajian ini tertumpu kepada analisis kekerapan dan keterukan berbagai-bagai faktor yang mengakibatkan perubahan dalam projek pembinaan rangkaian pembetungan. Adalah penting bagi sesebuah syrikat bukan sahaja mengetahui kos perubahan, tetapi juga mengenal pasti perkara-perkara yang perlu diberi perhatian untuk mengurangkan kos-kos sedemikian dalam projek akan datang. Kesemua data dan maklumat yang diperlukan diperolehi dari fail-fail arkib bagi tiga belas projek yang disahkan melalui temubual. Data-data dikategori untuk menganalisis kekerapan dan keterukan faktor-faktor. Jadual dan carta digunakan untuk menunjukkan hasil-hasil kajian. Daripada hasil analisis, keadaan tapak yang berbeza merupakan faktor utama yang mengakibatkan perubahan. Faktor-faktor ini menyumbangkan 49.3% daripada jumlah bilangan perubahan, 56.2% daripada jumlah kos perubahan dan 3.8% daripada jumlah kos projek. Dua ciri projek, iaitu nilai anugerah kontrak dan gred pendaftaran kontraktor dengan Lembaga Pembangunan Industri Pembinaan (mewakili pengkhususan, kedudukan kewangan dan sumber-sumber lain kontraktor) menunjukkan penyebab yang tertentu dengan perubahan. Kata kunci: perubahan; kekerapan; keterukan; pembetungan; rangkaian; pengkhususan Variations in construction have long been a debatable issue among the different participants involved in construction projects. However, only a few formal studies have been carried out to analyse its couses and effects. This study is focused on the frequency and severity of various factors causing variations in sewerage networks construction projects. It is important for a company not only to know the variation costs, but also to identify the most likely areas on which to focus in order to reduce these costs for the future projects. All the necessary data and information are obtained from archival files of thirteen projects and verified through interviews. These data are categorised to analyse the frequency and severity of factors. Tables and charts are presented to show the research findings. From the analysis, differing site conditions appear to be the major factors contributing to variations. They average 49.3% of the total number of variations, 56.2% of the total variation costs and 3.8% of the total project costs. Two project characteristics i.e. contract award value and the contractor´s registration grade with the Construction Industry Development Board (which represents the contractor´s specialisation, financial and other resources standing) show certain causal relationships with variations. Key words: variation; frequency; severity; sewerage; network; specialisation

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.
