The oil and gas industry form the main resource of economy in Iraq and constructing any project in such sectors requires a huge amount of expenses due to the unique requirements that oil and gas facilities required in such projects. Therefore, adopting an appropriate technological approach such as building information modeling (BIM) which is unfortunately not adopted yet in Iraq is essential to successfully deliver these projects. Thus, this paper aimed to introduce BIM to Iraq through Basra Oil Company (BOC) which is one of the biggest public oil and gas companies in Iraq.

The related literature of journals articles, conference proceedings and published reports have been reviewed. As a result, firstly: a hypothesis has been derived that is “If Basra Oil Company (BOC) adopts and applies BIM approach instead of the 2D approach currently used to manage its projects, the company can overcome several constraints in managing its projects that associated with such 2D traditional approach”; secondly: homogenous, consistence and reliable web-based questionnaire has been designed as its Cronbach’s alpha equal to 0.897 and 0.711 for BIM benefits and barriers, respectively. This questionnaire distributed to the BOC related professionals to test such hypothesis by investigating their readiness and accepting of BIM approach and to rank BIM barriers based on five-point Likert scale.

Based on the analysis using IBM SPSS Statistics 26 of 115 responses, almost 50% of the respondents had experience 11–15 years, while 22.6% had experience more than 15 years in oil and gas industry construction projects. Those participants were from diverse engineering majors that are: 4.3% Architectural Engineers, 31.3% Civil Engineers, 20% Mechanical Engineers, 22.6% Electrical Engineers and 21.7% from other engineering majors. The respondents’ departments demography was 16.5% of design department, 12.2% of construction department, 20.9% of Project Management Department, 12.2% of Maintenance department, 4.3% of HSE Department, 13% of Production Department and 20.9% of “Other Department.” The study resulted in 1: accepting BIM approach to be an alternative of current 2D-traditional approach used by the company to manage and construct its projects, since mean of collected data is (4.4332), Kruskal–Wallis H test significance values were 0.398 and 0.372; and ANOVA test significance values were 0.433 and 0.599 among Engineering Majors groups and Company’s Department groups, respectively. 2: Disclosed and sequenced BIM barriers in the company based on their criticality. 3: verifying reliably how BIM attributes are important to oil and gas construction projects in Iraq, 4: the company top management and company policies are the most critical potential factors to hinder or adopt and implement BIM in the company, 5: while cost is not seen a critical barrier to implement BIM in the oil and gas sector.

The limitation of this study is the excluding of decision makers of BOC, thus more profound future studies need to be conducted where top management and decision makers are involved, particularly the present study demonstrated that support of company top management is the most critical factor which can help the company to adopt (BIM).

The study concludes that BIM approach is valuable for managing projects in oil and gas sector in Iraq and identify the originality in output by using the research method. This noble study provides a leverage for enhanced research to adopt and implement building information modeling (BIM) in Iraq as the study originally demonstrates benefits and identifies the critical barriers in BIM implementation to push the boundaries toward adopt Digitalization and reduce CO2 emission in Iraqi oil and gas sector. The study can be used as evidence and platform to encourage professionals and practitioners to present more sophisticated tools of BIM in the oil and gas industry, especially for facility and operation management. These findings achieved via oil and gas experts, and it is first time to achieve such findings from a case study in Iraqi oil and gas sector.

Procurement management in infrastructure development has gained considerable attention in developing countries. It is because of the success in the developed nations. Studies have shown that Nigeria's infrastructure development needs far exceed its current provision. Also, studies are scarce to reveal whether procurement management has been successful in infrastructure development projects in Nigeria. Therefore, this paper investigated the root cause of the perceived encumbrances impeding procurement management in infrastructure development projects and proffered policy measures to improve future Nigeria's infrastructure development.

Data were collected via unexplored exploratory virtual interviews and selected cases from secondary sources. The engaged construction and engineering consultants have been involved in the procurement management of infrastructure projects in Nigeria. Thematic analysis was adopted to analyse the collected data.

The root causes of the pitfalls that emerged from the study include lack of competition and transparency, embezzlement and mismanagement of public funds, snail speed bureaucracy and bottleneck and lack of skills and knowledge. Others are collusion/bid-rigging/price-fixing/cartel formation, corruption, lack of professionalism, unbridled politicking, embezzlement and mismanagement of public funds, incompetence of tender boards, lack of patriotism to national service and lack of government organisations’ procurement capacity.

This paper is restricted to unravelling the encumbrances in procurement management of Nigeria's infrastructure development projects. Future research is desirable to adopt a quantitative approach for more extensive coverage and validate findings from this paper.

The paper findings, including those learnt from each case study evaluated, would undoubtedly influence policymakers and construction and engineering practitioners on the key strategies to employ in implementing future procurement management in Nigeria's infrastructure development projects.

This paper would assist policymakers and other stakeholders desirous of improved infrastructure to focus their priorities in mitigating the identified root cause hindering procurement management in Nigeria's infrastructure management.

The procurement reforms carried out by the Government of Ghana have led to the creation of the Public Procurement Authority and the passage of the Public Procurement (Amended) Act 2016. Nevertheless, many obstacles could prevent an open and fair competition during the procurement of works. This significantly affects the success of Ghanaian construction projects. Therefore, this paper aims to explore the factors to enhance the success of the contractor selection phase of the Ghanaian public labor-based construction project.

A quantitative research approach was adopted by this study. Data was collected through a self-administered questionnaire to 377 respondents across Ghana. The data was then analyzed using structural equation modeling.

This study revealed that external, project procedures and project management factors impact the Ghanaian labor-based contractor selection phase success.

This study is limited to the contractor selection phase of Ghanaian public labor-based projects and developing nations with similar socioeconomic characteristics.

Strict adherence to this study’s findings will enable the government to undertake more infrastructure projects to raise the standard of living for its populace.

Although several studies have been conducted to improve the success of construction projects in developing nations, very little focus has been placed on the success factors of the contractor selection phase of public construction projects. These findings are vital in discovering for the first-time factors influencing the success of the tender stage of public labor-based projects in Ghana and developing nations with similar socioeconomic characteristics.
