This study explored the extent to which health and safety (H&S) are considered in the procurement of public sector projects in Ghana. This is based on the background that procurement decisions have implications for project H&S management. The enormous size of public procurement projects offers opportunities for public clients to influence the behaviour of the construction market including the promotion of H&S through procurement. To date, no study has fully assessed the extent of H&S considerations in procurement decisions for public sector construction projects in Ghana. To fill this gap, this research has provided an evidence-based assessment of H&S considerations in the various stages of the procurement process for public sector projects in Ghana. Through a questionnaire survey, data were collected from construction industry professionals in Ghana. The data were subjected to statistical analysis to evaluate the extent of H&S considerations. The findings suggest that H&S is given low priority in the procurement of public projects, because clear project objectives relating to H&S are not set, and adequate consideration is not given to H&S at the various procurement stages. Based on the findings, this research has made recommendations to promote H&S in public procurement in Ghana.

The current public procurement law (Law No. 4734) was established in Turkey in 2003. The current law has fundamental differences from the previous one, Law No. 2886, in that the current law's main objective is to increase the effective use of public resources. Although the current law was enacted nine years ago, no in-depth research has been undertaken related to the extent of public savings. Thus, the aim of this research is to analyze the performance of public investments for construction with respect to their success in achieving on time and within budget completion. Additionally, a comparison between the completion duration and budget of construction projects undertaken under the current and the previous law is presented. To achieve these goals, historical contract documents addressing 878 and 575 public construction projects undertaken under two laws, respectively, were analyzed. In this context, the data mining method, including decision trees, artificial neural network, and support vector machines, was applied to predict the duration and cost deviations of the construction projects during the tender process, and the results were compared. It was demonstrated that the current law has contributed substantially towards the completion of the projects within estimated or envisaged durations and costs. The findings of this research can be generalized to countries with similar economical and organizational structures with Turkey.

Saudi Arabia has had many issues in delivering mega construction projects, such as delays, high costs, and low customer satisfaction. Some studies show that around 70% of public projects in Saudi Arabia are delayed. One factor that might be causing these performance issues is the traditional low bid contracting system in Saudi Arabia, or the Saudi procurement system. In Saudi Arabia, owners select contractors based only upon the lowest price. This paper researched ways to modify the current Saudi procurement system and show quick and simple modifications that can be done to improve the low performance. This research proposes that by adding the clarification phase from the Performance Information Procurement System (PIPS) to the Saudi traditional procurement process could greatly improve construction performance. The clarification phase requires the selected contractor to submit a project scope, detailed and milestone schedule, potential risks that they do not control, and performance measurement before a contract is awarded. The PIPS system is one of the most successful systems around the world, which shows success rate of 98% in six different countries with risk and cost reduction up to 30%. The clarification phase has been identified as the most important step in the PIPS to ensuring a successful project. This paper conducted a survey among construction professionals in Saudi Arabia, including 157 engineers, 33 consultants 9 owners, 5 vendors, 13 academics, and 28 architects, in order to develop the public procurement system in Saudi Arabia. The participants work in government sectors with an interest in the Saudi Arabian procurement system. The survey confirmed that professionals in the Saudi construction industry believe that the procurement system should be changed and that the inclusion of the clarification phase to the procurement system is a way to improve the procurement system.

Scope management in the form of reduction lists was integrated in the quality assurance scheme for Norwegian public projects in 2001. This article presents findings on the actual use of reduction lists for major public construction projects Project representatives were contacted to obtain information about the actual use of pre-defined potential scope reductions. Eight of the 14 studied projects did not implement any of the predefined reductions. Six projects implemented some of the reductions. The scope reductions on the reduction lists are very specific and detailed, unlike general theory on scope management and cost control. However, the findings from the study are in line with the general theory; it was the most general scope and cost reductions that where used in practice. The study subsequently looked into the relationship between scope reductions and sustainability. Although the most frequently observed reduction was of the category “reduced quality or functionality”, sustainability was rarely affected with the notable exception of the railway infrastructure projects.

Abstract The construction industry in Pakistan is experiencing a surge in public sector projects due to major investments in infrastructure projects. Project delays and cost overrun are common features in public sector construction projects in Pakistan. Therefore, an understanding of the causes of time and cost overrun in public projects is essential. This paper investigates delay and cost overrun factors within the context of public sector projects in Pakistan. This study identifies 48 potential factors from existing literature and semi-structured interviews were used to refine the identified factors into ten categories. A questionnaire survey was used to establish a hierarchy of factors using descriptive statistics. The results showed that the major causes of time overruns in public projects were (1) legal issues, such as court stay orders, land acquisition, relocation of public facilities; (2) technical errors leading to low-quality drawings, rework, and errors at bidding stage; and (3) Poor project management. The findings of this research contribute to understanding the causes of project delays in public sector projects in Pakistan.

Emerging construction practices such as building information modelling (BIM), prefabrication construction, green building, and integrated project delivery methods are gaining momentum in China, with great potential due to the size of its construction market. Through this, the sustainability level of China’s construction industry is expected to be enhanced from the economic, social and environmental perspectives. So far, there has been limited understanding of how BIM, as a digital technology, would affect other contemporary sustainable construction practices from the industry professionals’ point of view. Limited studies have been carried out to study the regional differences of these contemporary sustainable practices in China. This study adopted a questionnaire-based approach targeting industry professionals from three different metropolitan cities (Shanghai, Guangzhou, and Wenzhou).The follow-up comprehensive statistical analysis revealed that with regards to these contemporary sustainable construction practices, survey participants held much varied views on the growth of renovation projects, traditional Design–Bid–Build delivery, and conventional on-site construction methods. These three types were also generally perceived to have weak correlation with BIM application. Regional comparison further conveyed information on differences in perceptions among survey respondents from these three cities. For example, respondents from Wenzhou perceived more positive effects of BIM use in conventional construction projects. This research addressed the inter-correlation among these emerging sustainable construction practices, as well as the regional differences in China’s construction market. The findings provide insights and the big picture for both governmental authorities and industry practitioners on the latest sustainable practices of China’s construction industry. Recommendations are also offered towards improved economic, social and environmental sustainability performance for construction projects in the country.

Building Information Modelling (BIM) is a technology and process that are transforming way of designing, constructing, operating and using the building or facility. In essence, BIM models is a platform for collaboration as it encourages intensive communication and interdependence among multidisciplinary project members. In Malaysia’s BIM Guide, this collaborative process can be seen in Level 2 BIM Maturity which all designers engaged in projects work together to create a single computer-generated 3D Model. From this process, many benefits that BIM promises such as clash free construction, quality of design and greater certainty could be achieved. Therefore, the Malaysian Government announced the implementation of at least 40% of Level 2 BIM for public projects costing RM100 million and above in 2019. However, despite mutual understanding between construction players, the full integration of BIM in the project lifecycle seems to be a daunting task. In the context of the Malaysian Public Sector, many uncertainties could arise pertaining to legal and contractual matters i.e. whether or not the existing contractual instruments are able to support the collaborative environment and digital information sharing that Level 2 BIM engenders. This paper presents a narrative review of published literature on the concept of Level 2 BIM and contractual consideration based on the utilisation of BIM within Malaysian Public construction projects, which includes books, government publications, conference presentation slides, newspaper articles and paper-based journal articles. This paper concludes that in order to legitimise multidisciplinary collaboration and integration of information in BIM within existing standard forms of contract, the development of a contract protocol and suitable procurement model are necessary.

Direct Labour procurement method has been identified as one of several procurement route alternatives used for the delivery of construction projects. This study assessed Direct Labour as a procurement route for the delivery of infrastructure within the Metropolitan, Municipal and District Assemblies (MMDAs) in Ghana. A qualitative research approach was employed using in-depth interviews conducted with ten (10) professionals who were purposively sampled from the Works Departments of the Kumasi, Accra and Tema Metropolitan Assemblies in Ghana. The qualitative data was then analysed using content analysis. Direct Labour has been revealed by this study as an effective procurement method which can be employed by the MMDAs in Ghana for the delivery of public infrastructure. The findings of the study also indicate that, the benefits of the Direct Labour procurement route include the elimination of profits to contractors and its idealness for the execution of emergency works. However, Direct Labour as a form of procurement is not used on new MMDA construction projects because the Public Procurement Act 2003 (Act 663) of Ghana as Amended in 2016, does not clearly stipulate its usage on new projects. Direct Labour procurement is used within the MMDAs mainly for maintenance works on public projects. The findings of the study would prove useful for policy re-evaluation, especially regarding the reformation of the Public Procurement Act, 2003 (Act 663) as Amended in 2016 to include Direct Labour as one of the procurement routes for the delivery of infrastructure. This would enable the MMDAs to adopt it not only for maintenance works, but also for the execution of new infrastructural projects in order to benefit from its numerous advantages.

In order to establish a gap to be filled in a particular field, there is a need to gather information that allows the researcher to identify and analyse the current state of researches on the topic. Contingency sum estimation for projects plays an important role for inclusion for risk taken by the contractor on the bid amount. This is good in order to meet project objectives (cost, time, quality, health and safety, and environment). The main function of contingency sum is to cater forvariations that arise during the construction phase of projects. The aim of the study is to identifying and examine the various methods for estimating contingency sum for projects with a view to propose an appropriate method which will be suitable for a specific project in order to increase accuracy and reduce cost overrun. A literature review of selected papers (journals, conference proceedings and theses) on contingency estimation was carried out. The major findings from this study is that most studies were carried out on building projects while few were carried out on highway projects. From the analysis carried out, no single method of estimating has been effective for all types of projects. These methods of estimating contingency sums have developed over the years as a result of shortcomings of one method after the other. It is therefore recommended that peculiarity of each project, ease of using each of the methods and accuracy of the estimates needed should be the basis of choosing method of estimating contingency sum.
