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).

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.

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.

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.

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.

The Chinese civilization is an important part of the history of mankind. The purpose of this paper is to show that there are project management lessons to be learned from Chinese history, including that relating to the management of the building process in ancient China.

Through a review of the literature, this paper discusses the key management and economic practices in the building process of ancient China and highlights these practices from an important document, the Yingzao Fashi or (“Treatise on Architectural Methods”), that was compared with the modern‐day project management framework.

This paper explains the official systems instituted for public projects; the management of labour, design and planning of construction works; quantity surveying practices; the use, control and recycling of building materials; and inspection of building elements in ancient China.

The study suggests that lessons in the principles of construction project management in ancient China bear many similarities with the nine areas of modern‐day project management body of knowledge relating to integration, scope, time, cost, quality, human resource, communications, risk, and procurement management. An area for future research would be to compare the Yingzao Fashi with modern‐day codes of practice for building works to determine which of its “ancient” provisions relating to quality management are still relevant today.

It was found that much emphasis was placed by the ancient Chinese on the quality aspects of prominent building projects. This is one facet from which modern‐day project managers and clients can draw lessons.

In many countries, public procurement of goods, services and works is required to serve wider social purposes apart from the needs of the user agencies (which may be referred to as social responsibility procurement). In recent years, reforms have been implemented in the countries of East Asia to promote social responsibility procurement. They have entailed four main types of social responsibility: (a) supporting small and medium enterprises; (b) creating opportunities for small or start up venture firms; (c) fostering environmental sustainability through green purchasing, and environmentally sustainable construction (in the case of public works); (d) promoting work safety in site management in public works. The paper will examine the reforms in the countries of the region under which various preferential arrangements have been implemented to meet these objectives. It will consider why the reforms were adopted and also the differences between the countries of the region in the priority given to each of the reforms.
