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.

Purpose The purpose of this paper is to examine the relationship between environmental management practices (EMP) and competitive operational performance with respect to reduced cost, improved quality, improved flexibility and improved delivery as well as overall environmental performance, of firms, using data from a developing country. Design/methodology/approach The study employed a survey approach with responses from 164 informants from different industries and used partial least squares structural equation modeling to examine the relationship between EMP and competitive operational performance and their overall impact on the environmental performance of firms. Findings The results indicate that EMP by firms have a significant positive effect on firms’ competitive operational performance. Again, firms’ competitive operational performance has a partial positive effect on the overall environmental performance. It was also realized that the EMP initiated by a firm have a direct positive impact on the overall environmental performance of the firm. Research limitations/implications There is the need for organizations to take steps to plan and implement EMP since it is likely to enhance their competitive operational performance as well as their overall environmental performance. Practical implications The findings demonstrate the impact of EMP on competitive operational performance as well as on the overall environmental performance of firms. This is important as firms struggle with balancing investments in those practices against the perceived benefits that might be obtained from the practices. Originality/value The work provides insights and adds to the literature in the area of EMP and firm performance by providing evidence from a developing country environment. This study is among the few that have investigated the impact of EMP on firm performance in developing country environments.

Purpose In Ghana, the duration of construction projects from inception to completion is becoming a great concern, recently, especially among clients and beneficiaries, because of the rising interest rates, inflation, development plan targets, among other factors. Hence the need to understand the causes of delays and cost overrun in the construction sector has become more important than ever. This study therefore aims to identify the major factors underlying time and cost overruns in projects related to the education sector in Ghana to proffer practical solutions in addressing them. Design/methodology/approach The study conducted a survey among clients’ consultants and representatives of the contractors working on about 60 government school projects. A relative importance index was used to determine the relative effects of the factors causing construction time and cost overruns. Findings The key factors causing construction time overrun were: financial problems, unrealistic contract durations imposed by clients, poorly defined project scope, client-initiated variations, under-estimation of project cost by consultants, poor inspection/supervision of projects by consultants. Other factors were underestimation of project complexity by contractors, poor site management, inappropriate construction methods used by contractors and delays in the issuance of permits by government agencies. Factors affecting cost overruns were financial difficulty by client, delays in payments of completed works, variations in designs, lack of communications plans, poor feasibility and project analysis, poor financial management on site and material price fluctuations. Research limitations/implications The research was limited to only the educational sector projects. Practical implications Practically, this study highlights for the construction sector the critical factors causing project time and cost overruns in Ghana. Identification of these factors provides the basis for pragmatic solutions to enhance the chances of project success. Social implications The identification and solutions to project time and cost overruns, especially for educational sector projects, contribute toward making public goods more affordable and accessible to most citizens, particularly in developing countries. Originality/value This study contributes to the debate on factors causing project time and cost overruns in the construction sector especially from a developing country’s perspective.

Purpose The purpose of this paper is to investigate the causes of road construction delays in Ghana and identify appropriate mitigation measures. Design/methodology/approach The initial approach involved an empirical analysis of 48 road projects to quantify the extent of time. This was followed by a survey of the perception of road agency and donor partner officials of the critical causes of road project delays. Findings About 70 per cent of road projects experience delays and 52 per cent experience cost overruns. The average time overrun and cost overruns of road projects in Ghana was 17 months and US$1.15m (or 22.5 per cent), respectively. The five most critical causes of road construction delays were delay in finance and payment of completed work by owner (client-related); inadequate contractor experience (contractor-related); changes in scope by the owner during construction (client-related); delay to furnish and deliver the site to the contractor (client-related); and inflexible funding allocation for project items (donor-related). Research limitations/implications The most critical constraint of this study is the fact that findings are based on only the views of industry professional experts. It may be assumed that despite using broadly used terminology to refer to the causes of project delays, the interpretations by respondents may have differed from those intended. Further research could look at the correlation between time overrun and cost overrun using principle component analysis. Practical implications The identified delay factors are not unique to the road sector. From both academic and practical perspectives, the results emphasizes on the need for a holistic and integrated risk management model for the entire construction industry in Ghana. Originality/value The paper examined the causes of road project delays in the Ghanaian context and recommended remedial measures.

Purpose The purpose of this paper is to investigate the causes of scope creep on project completion in the real estate development industry in Ghana. Design/methodology/approach Both simple random sampling and convenience sampling techniques were used in selecting the respondents for the study. The respondents were experts working in the real estate development industry in Ghana. Findings Results from the study showed that the most critical factors that cause scope creep in the Ghanaian real estate development industry are client changes, unforeseen risks and unclear scope. Mitigating measures for addressing these factors were proposed. Research limitations/implications This paper is limited to causes of scope creep in the real estate development industry in Ghana based on data collected from only real estate development firms in Accra. Due to geographic constraints, the researcher was unable to sample real estate development companies across the entire country. The finding of this study may not be generalised since causes of scope creep can be unique to individual country contexts. Practical implication This paper has documented the critical causes of scope creep and its major impacts on project completion in the real estate development industry in Ghana. The results will help project managers in the industry to appreciate the causes of scope creep and its effect on project completion as well as increase the quality of economics on real estate management and reduce the costs and risks of housing of delivery in the country. Originality/value The paper examined the causes and mitigation of project scope creep in the Ghanaian context.
