Construction sites generate a large amount of material wastes and have become a common problem with associated risks in Ethiopia. However, the sources of such wastes are not well recognised. Therefore, the purpose of this research was to analyse the risk factors that contribute to material wastes in building construction projects. To achieve this goal, the factors that cause construction wastes were identified from literature and construction experts via focus group discussions and personal interviews. Following this, the factors were subjected to a questionnaire survey to identify the most critical factors of construction wastes. The questionnaire was distributed purposively to 85 construction experts representing contractors, consultants, and clients and 70 questionnaires were duly received for analysis. The data were analysed with a mean score and ranked to identify the most critical factors generating material wastes at construction sites. According to the results of the study frequent changes made to the design, poor strategies for waste minimisation, improper storage of material, poor site management, poor planning and supervision, and errors of contract document were the most critical factors causing construction wastes.

Cost Aspect

In the arena of cost baselines and project budgets, the construction industry is always famed and controversial. Owing to the paucity of funds or maladministration at various levels, there is 90 percent of project delay is fully stranded. While being a major contributor to a country's Gross Domestic Product, its sufficient potentiality has never been tapped. Maybe this dismaying climate is created by the cold-hearted, reckless and unscrupulous attitudes of construction industry stakeholders. The main objectives of this research is to determine the genesis of exceeded budget/cost in construction projects that affect cost management and to suggest appropriate measures to harness the construction industry's full potential. The key drivers that have positive or negative repercussions on the cost aspect of the projects are the administration, pundits and consumers or holders. For assessing the most common causative factors of exceeded cost in construction projects, the authors organized interactive discussions with construction industry pundits, designers, architects, schematic experts, and manufacturers. Moreover, the incumbent concerns in the construction industry were analyzed and examined to examine important factors. To underscore the key motives that drive the projects, directly and indirectly, a questionnaire was dispensed between the participants on the analysis in the cost of undergoing projects. Results of the study are the key interpretations which were drawn from this research paper are fraud, weak political engrossment, poor site management, hampering of site deployment, consultants inflexible approach, gold plating, faulty safety and healthcare management system. To remove these hurdles, I have recommended appropriate guidelines for preventing, reducing or mitigating the effects of these factors.

Construction Industry is evolving amid the fourth industrial revolution. Transportation, commerce, manufacturing and many other industries ripened the current technological advancement and are striving to utilise every development in the IT sector. The procurement of construction works is known to be very conventional and backward in the adoption of digitalisation. The construction industry's procurement and supply chain are blamed for the most inflated cost of construction projects, mainly attributed to a lack of transparency and trust between the industry stakeholders. This research explores the challenges of E-procurement adoption in the industry and identifies the potential opportunities for its usage. This investigation's data are acquired through interviews, and the data are analysed using qualitative content analysis. This study reveals compounding challenges (i.e., corruption and lack of commitment) that lead to the failure of such efforts in Nigeria and the potential prospects (i.e., transparency and efficiency). This study is essential in developing a more effective and transparent process of procurement so that the Nigerian construction industry is not be left behind in the fast-digitalising markets.

Claims Management

Background: Claims have increasingly become inevitable in construction projects. A great amount of money, time, and merit of claims are the most critical factors that prudent companies should not overlook. Objective: The objective of the study is to survey claim practices in the Vietnamese construction industry by collecting data from both contractors and consultants. Material and Methods: This paper presents findings that the lack of awareness of the on-site people is the major problem of claims management. Moreover, the inadequacy of supporting evidence, originating from the unawareness of personnel as well as improper documentation system, is also a serious problem causing the loss of chances to recover incurred damages. Conclusion: To overcome these problems, it is recommended that the management should pay more attention to these aspects in order to have effective claim management, by which unnecessary losses could substantially be reduced and deserving compensation would be recovered.

Purpose Successful implementation of construction projects is one of the crucial factors for the economic development of every country. The main part of the countries’ capital is allocated to civil and infrastructure projects annually, most of which are accomplished with delay. Construction projects are often criticized for overrunning time and budgets. Analyzing the factors causing delay is essential for omitting them and timely implementation of these projects. Due to the importance of oil projects, this study aims to investigate and analyze the factors causing a delay in Iran’s oil construction projects. Design/methodology/approach In this research, after a broad literature review, using the fuzzy Delphi method, a total of 75 delay factors were identified under 11 major categories of owner, contractor, consultant, equipment, labor, materials, design, contract and contractual relations, laws and regulations, environmental factors, and managerial factors. Then, by using the best-worst method, the factors were prioritized. Findings The results showed that sanction, governmental management systems, weak project management by the contractor, technical and managerial weaknesses of the consultant, financial problems and delay in payment by the owner, low efficiency of the equipment, low productivity of the workforce, changes in laws and regulations, inappropriate organizational structure linking to the project, changes in the design, and changes in the price of materials are the most crucial factors causing a delay in Iran’s oil construction projects. Research limitations/implications These findings are expected to have significant contributions to Iran’s oil construction industry in controlling the time overruns in construction contracts. Originality/value The main contribution of this study is to develop a comprehensive framework in which, causes of delay in Iran’s oil construction projects are addressed and prioritized.

Purpose – The purpose of this paper is to evaluate the waste occurrence level in the construction industry. It includes: first, identifying the mean value of frequency of waste occurrence according to respondents’ characteristics; second, identifying the main predictive factors for waste occurrence based on latent relationships between initial waste factors; and third, identifying the waste occurrence-level indicator (WOLI) for the construction industry based on the main waste measurement factors. Design/methodology/approach – A total of 19 waste factors were sorted from the literature review. A structured questionnaire was adopted to carry out the survey. The respondents are professionals who have much experience in construction and management of project. Shapiro-Wilk test of normality, Levene’s test, ANOVA test, and factor analysis technique were used to analyze the collected data. Findings – Frequency of waste occurrence in construction projects is quite high. There was no statistically and practically significant difference in means for waste occurrence between selected population categories. Based on factor analysis technique, there were five principal components extracted with 56.7 percent of total variance. The WOLI in the construction industry was found as 61.55 per the scale of 100. Research limitations/implications – The non-probability sampling was applied to collect data because of several certain limitations and difficulties. The number of data sets is relatively small. This study has only examined the frequency of waste occurrence without quantitative information. Practical implications – This is another study of waste factors in the construction industry, which is different from traditional waste studies. Originality/value – The contribution of this study to the practical project management is that a proposed evaluation sheet for WOLI could be applied for any construction firm.

Low Carbon Emission

The Malaysian construction  industry  significantly  contributes   as an empowerment to its development  vision  of  2020  by  reducing up to 40% of carbon emission. Moreover, the industry accounts as threat to the environment, not  only  in  terms  of natural  resources  consumption but  also  in emitting million tons of carbon emission annually. In fact, Malaysia is categorized the 30th in  the  world’s  ranking  in  carbon  emission  level. Several studies attempt to investigate and review barriers that face construction stakeholders in order to provide integration of sustainability in construction industry. However, the barriers were lacking in terms of addressing carbon emission aspects of sustainable practice and limit the emissions from construction projects in Malaysia. This paper investigates the major barriers of organization in achieving sustainability’s best practice. The identified barriers from the perspective of construction stakeholders in Malaysia were categorised based on factor analysis, which are professional and capacity, design and technologies, cost and finance, and, knowledge and culture.

Construction project delays caused by contractors and suppliers are the top problems in Thailand's oil and gas industries. Recognizing this importance and their relationships between factors can help reduce the risk of delays in construction projects. Therefore, this study set out to confirm factors and inspect relationships between delay factors of contractors and suppliers. A 16 item questionnaire survey was distributed to 134 managers, engineers, and supervisors in oil and gas platform construction projects in Thailand. A confirmatory factor analysis (CFA) was performed by the use of Amos Version 20 software program. The analysis results showed that delays caused by the contractors and suppliers had high relationships, due to high regression weighs. The delays caused by the contractors included seven factors which included poor site management and supervision (17%), lack of safety rules and regulations (16%), poor communication and coordination with others (15%), poor procurement system management (15%), defective components and mistakes during construction (14%), supplier payments lateness (13%), and poor planning and scheduling (10%). The delays caused by the suppliers included six factors which included the supply of unqualified and unskilled personnel (22%), supply of low efficiency equipment (20%), late delivery of materials and equipment (20%), supply of low quality materials (16%), late supply of workers (16%), and price escalation (5%).

Purpose The purpose of this paper is to present a systematic review of studies on CPD published between 1985 and 2018. Design/methodology/approach Before identifying common CPD, research trends were examined in terms of the number of publications in selected journals, as well as the contributions made by countries, institutions and researchers. Findings The findings reveal that researchers from developing countries have contributed the most to identifying the causes of CPD. A total of 149 causes of CPD were identified in a thorough review of 97 selected studies. Weather/climate conditions, poor communication, lack of coordination and conflicts between stakeholders, ineffective or improper planning, material shortages, financial problems, payment delays, equipment/plant shortage, lack of experience/qualification/competence among project stakeholders, labour shortages and poor site management were identified as the ten most common CPDs. Originality/value Being the first study of its type, this study provides insight into the research output related to this area and identifies a common set of CPDs, which may provide a better understanding of the key areas requiring attention where steps should be taken to minimise or control factors causing delays in construction projects.
