The planning function is a central component of management principles, enabling the success of construction project management. Many works have been highlighting the topic of critical success factors within construction organizations, yet the results have rarely covered planning behaviors within public construction work management; these less investigated areas were the aims of this study.

To fulfill this research aim, seven attributes of planning function were first derived through focus group studies, a focused literature review and focal interviews with industry practitioners. Then, a regression analysis design was employed with data collected from 139 professionals who are involved in public construction works management in Vietnam. The structural equation modeling technique with partial least-squares estimation was utilized to analyze the data.

The results revealed seven behavioral dimensions (i.e. Goals planning (PL1), Planning guidance (PL2), Strategic planning (PL3), Financial mobilization (PL4), Action plan (PL5), Expenditure planning (PL6) and Responsibility assignment (PL7)) to measure planning function management in terms of public construction works. The study also reveals that Goals planning (PL1), Financial mobilization (PL4), Expenditure planning (PL6) and Responsibility assignment (PL7) have significant effects on management effectiveness. At the same time, Goals planning (PL1) acts as the mediator of Planning guidance (PL2) and Strategic planning (PL3); while Action plan (PL5) specifies an indirect influence through the mediator of PL4, PL6 and PL7.

The success of this approach is expected to reinforce the contribution of the planning function and suggest a useful tool for supporting the professionals in managing public construction works.

This paper seeks to examine the contributions of rehabilitation and redevelopment projects to the labour force of the construction industry in Hong Kong. Major projects from the private and public sectors were critically examined and the manpower requirements and the tangible benefits in terms of wages arising from urban renewal were forecast.

The forecast of the expected persons to be engaged in the construction industry is based on trend regression model. Time series data of construction sites, both private and public, and persons engaged in the past ten years were forecasted for linear trend process for the next three years. From this, a reasonable estimate of man‐days to be engaged and wages to be incurred in the construction industry in the future can be obtained.

The results provide evidence that the impacts are positive. About 19.4 million man‐days and an income of HK$16.4 billion (3.8 per cent of the nominal GDP of Hong Kong in 2008) are anticipated in the short run. To meet urban regeneration needs, the Government should develop various vocational skills and enhance motivation and job search.

There are potential risks of error arising from the use of assumptions, limited sample size and data from the secondary resources.

Urban renewal works can generate more jobs. The ratio of development projects to rehabilitation works in terms of producing job opportunity by the same amount of budget is about 1 to 4.7. To meet urban regeneration needs, the Government should develop various vocational skills and enhance motivation and job search for renewal works.

Urban renewal attracts and stimulates investment, creates employment opportunities and improves the built environment of cities. Also, public rehabilitation works can play a moderate role in stabilizing the economy and the labour market.

The major contributions of this paper are: the estimated labour and financial resources to undertake such renewal works; and the more significant impact of rehabilitation work identified.

Though the Public Procurement Act of Ghana makes room for specific socio-economic policies (environmental, social, economic and other policies which are intended to promote social and economic impact), there is no explicit definition and provision for social value as an evaluation criterion, culminating in the absence of a definition in the Act. This paper elicits the conception and understanding of social value from stakeholders in the Ghanaian construction industry.

The study adopted a qualitative method that relied on a semi-structured interview of 30 participants purposively drawn from Western, Western North and Central regions of Ghana. An inductive thematic analysis approach, which involved identifying repetitions, exploring similarities and differences, noting linguistic connectors, and a framework were employed to analyse the data.

The study established no single definition or explanation for social value in the construction industry in Ghana. However, it was revealed from the study that the concept of social value could be defined from the functional perspective of the definer, particularly from the perspective of a Procurement Officer, Works Engineer, and a Quantity Surveyor. A new insight from the study that differs from the body of literature is that participants equated benefits derived from physically constructed projects as social value.

The study has implication for public administration and practice regarding the decision-making process in the construction industry in Ghana. It provides a vital awakening on social value as a criterion in evaluating construction works procurement in Ghana. The ability of participants to equate the benefits derived from executed construction projects as social value creates a new perspective on understanding the meaning of social value in the procurement of works construction.

The study contributes to the state-of-the-art and ongoing discourse on the concept of social value globally. The findings create an important catalyst for social value research in the Ghanaian construction industry.

The ‘lowest‐price wins’ philosophy has been a consistent theme of contractor selection over the years. To comprehensively elucidate this selection preference and compare it with the use of a multi‐criteria selection (MCS) approach in the tenderer evaluation process, this paper investigates MCS tender price selection preferences. That is, project‐specific criteria (PSC) and lowest‐price wins selection practices of UK construction clients, in both building and civil engineering works at in detail via results of the empirical survey. The investigation provides further insight into the evaluation of contractors' attributes (i.e. PSC). Levels of importance assigned (LIA) for each criterion were analysed (i.e. quantitative analysis of the differences in opinions and, variance amongst the respondents) in a multivariate statistical method. Importance attached by construction clients to the ‘lowest‐price wins’ philosophy is also presented. Contrast was made between the MCS approach and the ‘lowest‐price wins’ option amongst the surveyed construction clients. It was found that increased awareness of the use of PSC prevailed amongst the survey construction clients. This indicated that cost has to be tempered with the evaluation of PSC and the attempt of construction clients searching for a new evaluation paradigm (i.e. adoption of MCS approach rather than basing on the lowest‐price wins alone).

There is proliferation of regulatory frameworks and guidelines globally to implement social considerations in the procurement of construction projects. However, there are scanty empirical studies that have researched into the implementation of social consideration in the procurement of construction projects in Africa, particularly Ghana. Therefore, this study aims to examine the challenges that hinder the implementation of social value in the procurement of construction works in Ghana.

The study used an explanatory sequential mixed-methods design with an initial quantitative instrument phase, followed by a qualitative data collection phase. A critical comparative review of the related literature resulted in the identification of 29 challenges. A total of 100 questionnaire responses from professionals in the construction industry in Ghana based on the challenges on the implementation of social value were retrieved. The data obtained were coded with SPSS version 22, analysed descriptively (mean scores and standard deviation) and via inferential analysis (exploratory factor analysis). These data were then validated through semi-structured interviews with 10 professionals. The data obtained from the semi-structured validation interviews were analysed through the side-by-side comparison of the qualitative data with the quantitative data.

The results revealed that the critical challenges to the implementation of social value in the procurement of construction works can be clustered into three major components, i.e. weak processes and bureaucracy, the incongruence of social value with the traditional procurement process, and the misaligned social targets and erosion of public procurement principles. The interviewees agreed to and confirmed the criticality of these factors as challenges to the implementation of social value in the procurement of construction works.

A substantial number of studies have identified numerous challenges to the implementation of social value. This study presents a major cluster of challenges to the implementation of social value. Social value through construction procurement is a strategic tool globally and Ghana can leverage on its multiplier effects for social development.

The study extends the global discourse on social value in construction management literature by providing empirical evidence on the cluster of challenges that have the potential to hinder the implementation of social value in the procurement of construction works.

The aim of this study is to measure the impact of the factors affecting construction labor productivity by focusing on different types of construction works during and after the COVID-19 pandemic in Turkey, as well as discuss solutions and immediate actions.

This research was conducted in two steps. First, a quantitative survey was carried out to determine the dimension of factors negatively affecting construction labor productivity and the loss rate of different construction works from the employee perspective. The factors were identified through a literature review. The crucial relationships were highlighted as a result of a statistical analysis. Second, a survey was performed to determine the loss rate through a comparison of man-hour values before and after the beginning of the pandemic from the employer perspective. After an analysis and comparison of the results, semi-structured interviews were performed to discuss all findings and discover ways to mitigate the impacts of COVID-19 on construction labor productivity.

The results of the study clearly show that construction labor productivity was deeply affected by the coronavirus disease (COVID-19) pandemic. Legal obligations, such as social distancing, wearing masks, and limitations on the number of workers, have been major drivers for lower labor productivity. Such obligations have a profound impact on interior construction works, especially based on teamwork. Concerning employer and labor-related factors, problems with getting payments on time, loss of income, and financial hardships are the leading factors resulting in decreased worker performance. Excavation, insulation, and plastering works were determined as the most affected construction works under the influence of the COVID-19 pandemic.

The quantitative portion of this study is limited to a sample of respondents in the Turkish construction industry. Further research is necessary to provide an in-depth review into construction labor productivity in other countries with a larger respondent sample. Another limitation is sourced by the dynamics of the COVID-19 pandemic, which may turn out that some findings are outdated. Despite these limitations, the insights from this study may enable employers to understand the major drivers and deep impacts of labor productivity loss by uncovering the main vulnerabilities during the pandemic. Recommended measures may also help policy-makers and stakeholders in the construction industry take necessary and immediate actions to ensure better construction labor productivity.

The study may contribute to a better understanding of a pandemic's impact on labor productivity by focusing on both employee and employer perspectives, especially in developing countries. The paper may help employers decide which priority measures are required for each construction work separately. The study is crucial not only for minimizing the negative effects of the COVID-19 outbreak on labor productivity but also for preparing for the post-pandemic era.

This study aims to address gaps in the integration of Building Information Modelling (BIM) into procurement processes for construction works under the Portuguese Code of Public Contracts (CCP). The goal is to improve procurement procedures with practical recommendations benefiting both public and private sectors, and applicable in other countries, promoting efficient BIM use in construction projects.

The study involved a literature review and expert interviews to identify opportunities within the CCP related to construction procurement that impact BIM implementation during construction works. It critically analyzed these insights and proposed specific adjustments to the CCP to enhance BIM application in public construction works.

The study provides practical recommendations to address two main gaps identified in the literature: the neglect of non-specific digitalization factors influencing BIM implementation, and the lack of consideration for specific constraints in public procurement, particularly those dictated by legal frameworks like the CCP. These recommendations aim to optimize traditional procurement provisions for public construction, thereby improving BIM utilization on-site.

The study’s social implications include enhanced transparency and efficiency in construction processes, leading to reduced delays and costs for both stakeholders and the public. By optimizing BIM practices, public resources can be used more effectively in construction projects. The research may also accelerate the adoption of advanced technologies in the industry and improve urban development through better-planned and executed infrastructure projects. Additionally, the study’s recommendations could serve as a model for other countries, fostering the adoption of higher construction standards on a global scale.

The study’s original contribution lies in its comprehensive examination of public procurement procedures, particularly within the CCP context, to enhance the utilization of BIM during construction works. It uniquely identifies literature gaps and provides practical recommendations addressing non-specific digitalization factors and legal constraints in public procurement.

In Australia, national harmonisation of occupational health and safety (OHS) regulation was pursued through the development of model Work Health and Safety legislation. The model Work Health and Safety Regulations specify that construction works above a threshold cost of AU$250,000 are deemed to be construction projects requiring the appointment of a principal contractor with duties relating to OHS planning and coordination. The purpose of this paper is to explore the effectiveness of the monetary threshold as a suitable trigger for specific OHS planning and coordination duties.

Interviews were conducted with 46 Australian construction industry stakeholders, including union representatives, employer groups, construction firm representatives and regulators, as well as four international construction OHS experts, to explore perceptions about the effectiveness of the monetary threshold. Two construction scenarios were also modelled to test for variability in operation of the threshold by geographical location of works and design conditions.

The monetary threshold was perceived to be subject to two forms of capture problem, reflecting inadvertent capture of low risk works or failure to capture high risk works. Organisations were also reported to deliberately split contracts to avoid capture by the threshold. The cost-estimate modelling revealed inequalities and variation in the operation of the monetary threshold by geographic location and design specification.

The analysis suggests that limitations inherent in the use of a monetary threshold to trigger duties relating to OHS planning and coordination in construction works. Opportunities to use more sophisticated risk-based mechanisms are considered.

The study explores a fundamental challenge of risk-based OHS regulation, i.e., how to ensure that workers’ health and safety are adequately protected without creating an unnecessarily high regulatory burden. The research provides evidence that using a monetary value as a proxy measure for OHS risk in construction projects may be problematic.

The purpose of this paper is to provide a critical review of the building regulations and the building control system in Portugal. The organisation, content, and authorities responsible for building regulations are described and an overview is provided of the main stages of the building permit procedure.

The paper reviews the relevant legal and regulatory provisions and discusses these in the context of commentary published by the various professional associations.

The Portuguese building regulation system has undergone significant changes in the last 20 years. Almost all building regulations currently in force are approved during that period. Some of these are resulted from the implementation of European Directives. Others are changed due to advances in scientific knowledge. Changes in the building control system have mainly been driven by the changing demands of present‐day practice, in particular, the absence of sufficient municipal technicians, and the need to expedite building control procedures. The solution has been to move away from public building control and to make private parties responsible for compliance with building regulations. The paper concludes that, although there have been significant improvements in the building regulation system over recent years, two structural problems nevertheless persist. First, building regulations continue to be complex and fragmented, and second the qualifications of technicians are still not adequately defined.

A structured overview of the system is provided and the main weaknesses are identified. The proposals for change are suggested by professional associations are summarised, and possible improvements are suggested.

This study provides a framework for comparing construction management contracts in the UK and the US construction practices. It starts by reviewing previous studies on UK and US contracting practices and explores the main delivery methods, inform of comparison with construction management contracting systems. It examines construction management contracting types, processes and procedures and interaction between the construction manager and other stakeholders. This study was based on a literature review and the result shows the similarities and differences between the American and British CM systems within each practice and between both practices; the distribution of responsibilities and risks both in pre‐construction and during the construction stages; and allocation of responsibility in both practices.
