Purpose – The purpose of this paper is to assess the causes and effects of delays in public sector housing projects in Ghana. Design/methodology/approach – A purposive sampling approach was used in selecting the respondents for the study. These were experts working on various state housing construction projects in Ghana. Findings – Results from the study showed that the critical factors that contribute to project delays in Ghana are; delay in payment to contractor/supplier, inflation/price fluctuation, price increases in materials, inadequate funds from sponsors/clients, variation orders and poor financial/capital market. The critical effects of delays are cost overrun, time overrun, litigation, lack of continuity by client and arbitration. Research limitations/implications – This paper is limited to causes and effects of project delays in Ghana based on data collected from only one state institution. Due to geographic constraints the researchers were unable to sample state institutions across Ghana involved in various housing projects. Practical implications – This paper has documented the critical state housing construction project delay factors in Ghana. The results will help project managers and policymakers appreciate the effects of these delays on project outcomes. Social implications – Measures aimed at reducing cost of housing projects in Ghana can translate into significant benefits to the poor and support achievement of government objective of providing affordable housing to low income citizens. Originality/value – This research focussed on the key factors and best practices that lead to the success of state housing projects within the Ghanaian context.

Low Income Housing

Purpose – This paper aims to develop a set of affordable space and dimensional standards for market-driven low-income housing in Indian context for the purpose of mass production using industrialised building system. Design/methodology/approach – For this, the paper first explains the significance of standardisation from the literature and revisits the codes and contemporary practices in industrialised building system (IBS) in India. Next, it undertakes a market survey of ongoing/completed housing projects to study the space/dimensions reflected in the market demand by the people. After considering conditions like modular grid suitability and provisions of code, it identifies a set of dimensional standards of activity spaces, emerging from the market study. It also suggests a framework of modular units showing the incremental attachment possibility for component-based construction using IBS. These standards and design frameworks will make the path for developing various products and components towards an open system in India. Findings – The paper gives an insight of the market trends of low-income housing, focusing on unit designs and spatial elements. Research limitations/implications – Local contextualisation during the unit designs will be required and that is not addressed in this paper. Practical implications – This will benefit developers, manufacturers, designers as well as policymakers towards a market-driven housing delivery using IBS. Social implications – As a result of this standardisation, housing delivery will be faster and there will be more numbers of market-driven affordable housing in masses for low-income people, thus solving housing shortage. Originality/value – A developing country like India is a diversified country having many geographical and social variations. Such standardisation for a space and design framework has never been attempted before and will make a contribution for the public housing sector.

The problem of not enough public housing for low-income citizens is very urgent in the entire world. This article is dedicated to the topical question; how do we select optimal investment projects and implement successful investment programs to fund public housing projects better. We have formulated basic principles for the formation of an optimal portfolio to use as a standard for investment programs for public housing construction projects. As selection criteria, instead of profitability and risk offered in classical portfolio theory to which private investors are paying attention, we propose the use of social satisfaction survey results and amount of available funding to determine the effectiveness of the programs. We have developed several mathematical models that help aid in the selection of investment projects based on these new requirements. The application of these models in the selected projects selection within the framework of investment programs of public housing construction will allow the most effective use of funds directed to the development of the public housing

Purpose – The delivery of construction projects in Malaysia is plagued by time overruns, which turns what should have been successful projects into those incurring additional costs, or money-losing ventures; as well as leading to various other unexpected negative effects and faute de mieux situations. The purpose of this research is to assess those factors leading to time overrun in Malaysian construction projects. The perceptions of public and private sectors, contractors, clients, and consultants are compared relative to a list of factors derived from the review of extant literature in project delay. Design/methodology/approach – The research data were collected through an industry-wide questionnaire survey circulated across the Malaysian construction industry. The research develops a list of 84 time overrun factors. Responses were collected from 49 clients, 51 contractors, and 105 consultants, to explore and analyse the major factors that are responsible for causing time overrun based on sectors (public and private), organisations (clients, contractors and consultants) and professional roles. Findings – Project delays beyond contract dates are predominantly caused by contractors and are usually associated with financial factors. “Cash flow problems faced by the contractors” was found the major factor, which contributed to project delays, whereas “storage on site” was seen as the least significant factor. Practical implications – It is noteworthy that the findings in this research have a regional focus; it is, therefore, suggested that readers from other sections of the world exercise caution in applying the findings. As it is believed that every construction industry has its nature, culture and regulations, these factors can change as a result of such differences. Originality/value – This research provides stakeholders with information on factors, which, if properly understood, can make project delays less likely.

Affordable housing has remained a major challenge in Nigeria, as housing costs have continued to rise beyond the reach of the low income population. This paper explores the use of waste products like rice husk as alternative materials for housing construction. Rice husk is abundant as a waste product in areas where rice is processed commercially in Southeast Nigeria. The aim of the study is to create rice husk blocks that are cheap, lightweight, and appropriate for use in low income housing construction. The study was conducted through experimentation in the Building Technology workshop of Federal Polytechnic Nekede. A series of trial mixes were done involving a wide range of materials and mix proportions. Rice husk, Portland cement, and cassava starch, were found to be the most appropriate components for the blocks. The blocks produced were of good appearance, and lightweight. Five samples of solid core blocks measuring 150x150x150mm were tested in Strength of Materials laboratory of the Federal University of Technology Owerri. The average compressive strength of the blocks was 0.26N/mm2, which is below the Nigerian Industrial Standard NIS 87:2007. The blocks produced were considered appropriate for use as non-load bearing partitions and not structural walls. The result of the study is promising because the rice husk blocks help address the waste management problem in affected areas, and could also be an important component of a potentially useful material. This paper recommends further research in the area of improving the strength of the blocks, to make them usable as structural components in low rise buildings.

Purpose This study aims to identify and establish effective housing financing concepts to be adopted by government in achieving its mandate of providing sustainable affordable housing for the poor to decrease the building of shacks, as well as proposing solutions to the housing deficit in South Africa. A rise in demand and shortage in supply of housing calls for the need to address issues of affordable housing in South Africa, and developing countries in general, to ensure a stable and promising future for poor families. Design/methodology/approach Literature has revealed that the South African government, at all levels, accorded high priority to the provision of low-cost housing. Thus, government has adopted subsidy payment as a method of financing affordable housing to ensure that houses are allocated free to the beneficiaries. This also addresses the historically race-based inequalities of the past, but unfortunately, this has not been fully realised. This study uses a sequential mixed method approach, where private housing developers and general building contractors were the research participants. The qualitative data were analysed using a case-by-case analysis, and quantitative data were analysed using a descriptive statistical technique on SPSS. Findings The results of the qualitative analysis reveal a gross abuse of the housing subsidies system by the beneficiaries of government-funded housing in South Africa. This is evident from illegal sale of the houses below market value. This has led to a continual building of shacks and an increased number of people on the housing waiting list instead of a decrease in the housing deficit. The results from quantitative analysis affirm the use of “Mortgage Payment Subsidies, Mortgage Payment Deductions, Down-Payment Grant and Mortgage Interest Deductions” as viable alternatives to subsidy payment currently in use to finance affordable housing projects by the South African Government. Practical implications At the moment, the focus of the South African National Government is continual provision of free housing to the historically disadvantage citizens, but the housing financing method being used encourages unapproved transfer of ownership in the affordable housing sector. This study thus recommends the use of an all-inclusive housing financing method that requires a monetary contribution from the beneficiaries to enable them take control of the process. Originality/value The relational interface model proposed in this study will reduce pressure on government budgetary provision for housing and guarantee quick return of private developers’ investment in housing. Government must, as a matter of urgency, launch a continuous awareness programme to educate the low-income population on the value and the long-term benefits of the housing.

PurposeThis study aims to investigate and model the complex dynamics of innovation enablers in construction projects aiming to develop a framework identifying actions for clients to promote innovation.Design/methodology/approachThrough a comprehensive literature review, a conceptual model was previously derived to explain the client-driven enablers in promoting innovation. This was tested using the data from 131 Australian construction projects. Statistical analysis was conducted on the data using factor analysis and correlation analysis to test the model, which was validated using the case study approach. The testing and validating aspects are explained in this paper.FindingsThe constructs of the recommended model are idea harnessing, relationship enhancement, incentivization and project team fitness.Research limitations/implicationsThe difficulty of analyzing the complex dynamics happening within projects in relation to innovation has been a barrier to progress research in this area. The introduction of this model would pave the way for researchers to explore this area with ease.Originality/valueAs revealed in the detailed literature review undertaken, this is the first time that a comprehensive study has been conducted to identify client-led innovation enablers for construction projects. The results would benefit industry practitioners to achieve enhanced project outcomes in construction projects through innovation.

Project Level

Purpose – This research aims to investigate the impacts of project culture on the performance of construction projects. Cultural issues in the construction industry have attracted growing attention from both practitioners and academia. However, there are few studies on culture issues at the project level. The influence of project culture has not traditionally been on the research radar. Design/methodology/approach – A case study approach, utilising questionnaire surveys, in-depth interviews and review of project documents, was used to investigate project culture and its associated impacts in two major hospital projects. Findings – The results indicated that project culture played an important role in achieving harmonious relationships between project participants and better project outcomes in terms of schedule, functionality, satisfaction with the process, satisfaction with the relationships, environmental issues addressed commercial success, further business opportunities and overall performance. Case 1 outperformed Case 2 in these performance indicators. Similarly, it became clear that the project’s culture should be developed from the outset and sustained during the project period. Furthermore, it was also highlighted that the project culture should be translated to all levels of the supply chain, i.e. sub-contractors and suppliers. Practical implications – The findings enabled the client to understand the role of project culture and actively commit towards the development and maintenance of the project culture from very early on. It also helps project teams to understand how to deal with cultural issues at the project level. Originality/value – This study is one of limited empirical studies that offer in-depth insights of how project culture affects the performance of construction projects. It is also the first study of hospital projects on the research topic.

Practical Implications

Purpose – Using projects executed with both traditional and integrated procurement methods, the study sought to investigate relationships that exist among project participants and the influence of those relationships on cost growth. The paper aims to discuss these issues. Design/methodology/approach – Questionnaires were administered among 274 construction projects located in 12 states including the Federal Capital Territory of Nigeria. Responses were obtained from 96 projects. Data were subjected to both descriptive and inferential analyses. Findings – In terms of cordiality, relationships between client and contractors ranked highest, while those among in-house project teams ranked lowest. Cost growth or cost overrun is significantly correlated with client-contractor relationship, consultant-contractor relationship, client-consultant-contractor relationship and in-house team relationships. No association between procurement method and cost growth was found. Research limitations/implications – The limitation of generalizability of results due to the sampling method used is acknowledged. One implication of the findings is that in the context of this research, any explanation for cost growth has to be found outside procurement methods. Practical implications – Findings may assist project participants on variables to consider in anticipating, preventing or managing cost growth in building construction projects, beyond formularization of contracts and structures. Originality/value – The research has uniquely investigated the association between intangible project team relationships and tangible variable of cost growth.
