Purpose Project delay is becoming a problem in the Sultanate of Oman as evidenced by many delayed projects across the country. The purpose of this study is to examine causes and effects of delays in megaprojects in the Sultanate of Oman with recommendations to mitigate same. Design/methodology/approach A systematic review of literature identifies through main stakeholders the numerous causes, impacts and methods of mitigating delay from previous studies. A questionnaire survey on Oman was carried out to sample opinions from the practitioners; 53 questionnaires were received and analysed using the relative importance index (RII) method. Findings The five most frequent causes of delay in the Sultanate of Oman, in rank order, are: selection of the lowest bid, instead of best bid for the client (RII: 0.698); the financial condition of the main contractor (RII: 0.664); delay in decision-making by the client (RII: 0.656); and poor construction planning by the main contractor (RII: 0.649). Also, the findings indicate that extra cost (RII: 0.754) and project time overrun (RII: 0.724) are the most significant effects of the delay in the Oman megaprojects. The use of experienced contractors and consultant (RII 0.675), efficient construction planning by the main contractor and effective site management and supervision (RII: 0.667) are essential mitigation methods of construction delay in Oman megaprojects. Originality/value The study recommends three-part novel solutions to mitigate delay in the Oman construction industry.

Purpose -Project management (PM) is a diverse discipline which covers the study of management practices. Different research approaches have been used in the study of PM but not much emphasis has been given to the constructive approach which is implicitly applied in most cases through managerial constructions. The purpose of this paper is to support the application of the constructive research approach to the construction PM discipline. It is also aimed at showing the rigour of the constructive research approach that satisfies the requirements of applied studies research. Design/methodology/approach -The study is carried out via extensive literature review and a demonstrative example of the development of the Specialist Task Organisation procurement approach through the six stages of the constructive research approach. Findings -The paper shows the applicability of the constructive research approach to construction and PM. The paper also highlights some criticisms that the constructive approach has not been firmly rooted in PM research and suggests some solutions.Research limitations/implications -The constructive research approach is applicable to the PM discipline because most research in this field is applied and practical. The paper specifically scrutinises and promotes the constructive research approach. Originality/value -The paper will provide an additional research tool in the PM discipline that produces innovative solutions which are grounded by valid research instruments. The impact of this paper will increase the popularity of this research methodology, generate and stimulate a debate to further explore its application and the development in the PM discipline.

PurposeThe purpose of this paper is to examine different categories of building project procurement routes based on organisational, contractual, financial and technical issues.Design/methodology/approachThe paper is based on review of literature and conditions of contracts. The UK construction industry serves as a general frame of reference. The Royal Institution of Chartered Surveyors survey of Contracts in Use from 1985 to 2004 is used to probe the share and value of contracts along different procurement routes and across different conditions of contracts in the UK. The logic is that the value and the share of contracts will indicate the behaviour of different procurement routes in the UK construction market while the in‐depth analysis of conditions of contracts will show the gaps and relationships between the general definition/categorisation and contractual context (conditions of contracts) of each of the procurement routes.FindingsThe preliminary result of the analysis shows that traditional routes remain the main type of procurement route for the construction project industry sector, within which different management and incentivisation systems are applied for greater efficiency. The conditions of contracts in the UK support this assertion by aligning different procurement routes to different conditions of contracts and additionally specifying different forms of agreements, special provisions and incentivisation in order to increase performance, reduce risks and improve compensation methods.Research limitations/implicationsThe study can serve as a learning opportunity for construction project stakeholders internationally, and clients in particular, to differentiate between procurement routes, management‐oriented systems, relational contracting and incentivisation.Originality/valueThe research provides an original assessment of construction procurement which can be used as intervening tool in different levels of private and public procurement strategies.

Purpose The outbreak of the Covid-19 pandemic has tested the resilience of the construction industry, putting the safety of workers and overall businesses at risk. This study aims to explore the different strategies adopted by construction companies to protect the health and well-being of employees, security of the construction sites and projects, and keep the overall business operational amid the Covid-19 pandemic. Design/methodology/approach A preliminary study that involves field study and survey research was used to collect data for the study. The results from the preliminary analysis served as inputs for constructing the questionnaire, which was analyzed using descriptive statistics, exploratory factor analysis and reliability analysis. Findings The results reveal that the key underlying measures put in place by construction businesses include restricted site access, support bubbling of office and site staff, enhanced hygiene and social distancing protocol, contract risk identification and mitigation, self-isolation measures and heightened construction site safety. Along with a further discussion of the underlying measures, the top-rated strategies that were adopted by construction firms are also discussed in the paper. Originality/value As many construction companies remained opened handling essential projects amid the pandemic, the study presents the effective and efficient strategies that were used in plowing through the trying times. This study provides the opportunity for construction companies that escaped the early impacts of Covid-19 due to site closure and policymakers to learn from the strategies adopted by construction companies that were operational amid the pandemic.
