The study investigates key performance indicators (KPIs) that could improve performance of public-private partnership (PPP) projects in Nigeria. The study objectives include a comparison of stakeholders’ perception on KPIs and to investigate if significant difference exists between stakeholders’perceptions on most KPIs. A structured questionnaire was used to collect information from various respondents who wererecently involved in PPP projects. Random sampling technique was used to select forty-five (45) respondents out of which thirty-one (31) responses were used for the data analysis. The results indicate that top KPIs for performance improvement are levels of design complexity and technological advancement, and return on investment. Stakeholders agree on most of the rankings of the KPIs. The general perception of stakeholders was similar on most KPIs except for a few divergent opinions. The study findings have an implication for policy and decision making such that stakeholders could pay special attention to the KPIs identified, that could improve construction project performance. Finally the study recommends further research to explore KPIs for other procurement options.

The purpose of this paper is to investigate if the various risk sources in Design and Build projects can be classified into three risk groups of cost, time and quality using the discriminant analysis technique. Literature search was undertaken to review issues of risk sources, classification of the identified risks into a risk structure, management of risks and effects of risks all on Design and Build projects as well as concepts of discriminant analysis as a statistical technique. This literature review was undertaken through the use of internet, published papers, journal articles and other published reports on risks in Design and Build projects. A research questionnaire was further designed to collect research information. This research study is a survey research that utilized cross-sectional design to capture the primary data. The data for the survey was collected in Nigeria. In all 40 questionnaires were sent to various respondents that included Architects, Engineers, Quantity Surveyors and Builders who had used Design and Build procurement method for their recently completed projects. Responses from these retrieved questionnaires that measured the impact of risks on Design and Build were analyzed using the discriminant analysis technique through the use of SPSS software package to build two discriminant models for classifying risks into cost, time and quality risk groups. Results of the study indicate that time overrun and poor quality are the two factors that discriminate between cost, time and quality related risk groups. These two discriminant functions explain the variation between the risk groups. All the discriminating variables of cost overrun, time overrun and poor quality demonstrate some relationships with the two discriminant functions. The two discriminant models built can classify risks in Design and Build projects into risk groups of cost, time and quality. These classifications models have 72% success rate of classification of risks in Design and Build projects. These models are strongly recommended for use of clients, Design and Build contractors and Risk Managers for the management, control and mitigation of future risks in new Design and Build projects. These models will offer appreciable improvements in risk management and mitigations which can enhance better management of future Design and Build projects. This study also recommends that clients and contractors using Design and Build approach should watch out for emerging issues of cost overrun and poor quality in their projects as these can dictate classification of newly encountered risks.

Several Literatures in construction management support the view that procurements have impacts on project performance. Aim of this study is to investigate the effects of procurement related factors of procurement selection criteria, tendering methods and variation orders on project performance. Purpose of the study is to evaluate the effects of procurement related factors on project performance. Snowballing sampling technique was used in selecting forty (40) construction organizations in Lagos metropolitan city that participated in the study and thirty-one (31) responses were secured from Architects, Builders, Engineers and Quantity Surveyors. Results of the study indicate that procurement selection criteria of cost, time, quality, project characteristics and external environmental factors have effects on project performance. Competitive, open and selective tendering methods have high impacts on project performance. No significant difference was found between the impacts of tendering methods on project performance. Variation orders impact project performance with time, cost overruns and disputes and it have effects on project performance. Conclusions are that procurement selection criteria, tendering methods and variation orders have impacts on project performance. Cost, time, quality related factors, tendering methods and variation orders strongly affect project performance. Recommendations to clients, stakeholders, practitioners and consultants are on the onset to consider tendering methods, use selective, open and competitive tendering approaches and discourage excessive variation orders during construction. Policy makers in government, clients, and private developers into housing projects should give adequate attention for selecting appropriate procurement and tendering methods for better management of future projects in Nigeria and other developing countries.

The philosophy of every maintenance practice and operation in any organization is usually to provide a structurally sound and aesthetically appealing environment throughout the life of a property. Maintenance has generally been referred to as all works carried out to keep and restore an item to a currently acceptable standard. This work evaluates the performance of facilities maintenance management in the maintenance of sport complexes in South-West Nigeria. The study research method includes physical observation, administration of questionnaires to measure performance. In order to gather information, structured questionnaires were administer at the study area (the six stadia covered), the management staff, the maintenance staff and the user of the facilities in each of the stadia, covering kiosk owner, sport men and women, spectators, and lover of sports. The study revealed some factors affecting performance in the maintenance of sports complexes among which are: funding, organizational structure, political factors, ownership types, and security. The study concluded that it is only when adequate fund is provided and fully utilized in the maintenance of sport complexes that one will enjoy the initial investment in them and the consequent accruing benefits from the complexes will be achieved. The study recommended among others facts that the government should set aside part of her annual budget to maintenance of the sport complexes so as to ensure their fitness and world class standard at all time which will consequently reduce the operating cost and increase the revenue generating capacity of the stadium.

2This paper examines building materials used in construction in Nigeria and asks whether local and conventional building materials are perceived by construction stakeholders to be more environmentally sustainable than innovative building materials. The reason for the investigation stems from a lack of clarity about which of these building material classifications is more environmentally sustainable. The study also aimed to establish whether stakeholders accept the claims made by manufacturers about the environmental sustainability of their building products. The environmental sustainability of the selected building materials was measured using indicators and metrics developed from the literature. The study established that there are no significant differences in the level of environmental impact among the four classes of building materials considered (local, conventional, recycled-content and innovative). In general terms, the cohort of innovative building materials/products is perceived to be 'greener' than local innovative building materials, which are considered to be environmentally better than conventional building materials. Based on the findings, this paper concludes that construction industry stakeholders do not acknowledge claims made by manufacturers about the environmental sustainability of their building materials.
