In the construction industry, the relationship between clients and contractors has been usually characterized by uncertainty and adversarial behaviour. More recently, their relationship is said to be changing from a traditional and arms-length basis to more collaborative forms, e.g. partnering. There is evidence that such collaborative forms can have a substantial impact on project performance, not only with regard to time, cost and quality objectives, but also with regard to more general outcomes, e.g. greater innovation and improved user satisfaction. However, such benefits are less well understood due to limited research and in particular an absence of robust and appropriate methods of evaluation. The purpose of this research is to address this shortfall and seek to evaluate these wider aspects of project performance relative to different degrees of collaborative working. To achieve this, collaborative working and project performance first need to be transformed into a measurable form by breaking them down into a variety of attributes or indicators. Surrounding these attributes/indicators, item statements are developed and a Likert Scale is then adopted for questionnaire design. Questionnaires were mainly administered by semi-structured interviews in which the client and contractor from the same project were invited to evaluate their collaborative working and the corresponding project performance. After unidimensionality and reliability testing for the composite measures, the response difference between client and contractor group is explored through conducting paired samples t-test. Subsequently, cluster analysis is conducted to produce a taxonomy of collaborative working and correlation and regression analysis are conducted to explore the associations between collaborative working and project performance. The final conclusion strongly supports the existence of a strong positive linear relationship between collaborative working and project performance, provides valuable regression formulas to make project performance predictions and gives a more precise classification of collaborative working to help reduce the confusion over its definitions in a novel way.

The success of any public-private partnership (PPP) project in a country is largely dependent on the country’s maturity on critical success factors (CSFs) that made PPP projects successful. Thus, identification of metrics and standards for measuring the maturity of stakeholder organisations on CSFs for PPP projects implementation remains a challenge. Though studies on CSFs for PPP projects abound, approaches of using CSFs to develop PPP process maturity received scarce attention. Against this backdrop, this research becomes imperative to create efficient and transparent operational strategies with a view to using CSFs to develop process maturity for stakeholder organisations in PPP projects in Nigeria. Data for the research were obtained through mixed methods approach namely: quantitative and qualitative approaches. Questionnaires were administered on five different stakeholder organisations comprised public sector authorities (i.e. ministries, department, and agencies), concessionaires, local lenders/banks, consultants, and contractors involved in different PPP projects implementation in Nigeria. The data collected were analysed using descriptive and inferential statistics. Also, the qualitative approach was conducted through an expert forum and six PPP infrastructure project case studies in Lagos metropolis, Nigeria. The expert forum was constituted to refine and verify the conceptual framework developed. Also, structured interviews were conducted with primary stakeholders in the six PPP infrastructure project case studies in the study area. The research identified fourteen CSFs that made PPP infrastructure projects successful in Nigeria. These CSFs were employed for capability maturity levels definition ranging from level 1(Ad hoc) to level 5(Optimising) in accordance to Capability Maturity Model (CMM) concept. This led to the development of stakeholder organisations capability enhancement framework (SOCEF) in PPP infrastructure projects in Nigeria. The framework was validated by PPP experts to ensure it is comprehensive, objective, practical, replicable, reliable, and suitable for use in Nigeria. Thus, a quantitative assessment tool was developed with the framework in assessing the current capability maturity levels of stakeholder organisations involved in PPP infrastructure projects on fourteen CSFs identified in this research. The findings revealed that public sector organisations were between maturity level 1 and maturity level 2 (out of 5 maturity levels) on CSFs applicable to them. The majority of the private sector organisations were in maturity level 2 on CSFs associated with them. It is established in this research that Nigeria’s maturity is between maturity level 1 and maturity level 2 (out of 5 maturity levels) on CSFs that made PPP infrastructure projects successful. The findings emanated from this research provided both the theoretical and practical contributions to knowledge. The theoretical contributions include the methodology for developing capability maturity levels in PPPs, new insights into the usefulness of CSFs in PPP projects, and contributed to the wider body of knowledge of process improvement in the construction industry at large. The practical contributions are the capability level definitions and enhancement framework for PPP practice, and the specific CSFs for PPP infrastructure projects in Nigeria. The framework developed in this research had provided the benchmark for the identification of methodical approach and standard to process improvement in PPP infrastructure projects in Nigeria. It is believed that the framework would provide a useful guide and roadmaps for improvement by indicating ‘what’ needs to be done by stakeholder organisations involved in PPP projects in achieving higher capability maturity levels on identified CSFs for PPP projects in Nigeria and developing countries at large. Thus, the framework could be used to benchmark future studies.

Crime Prevention Through Environmental Design (CPTED) is a concept which has developed over the past five decades through a range of fields. It is based on the premise that modifications to the built and natural environment can reduce both crime and fear, and improve the overall quality of life. CPTED relies on the cooperation of a variety of agencies; however, research has revealed important inherent difficulties regarding multi-agency working and that current practice is neither sustainable nor does it consider social characteristics which may impact upon crime and the effectiveness of CPTED initiatives. Criticisms of diverse factors relating to CPTED have been expressed but how robust such criticisms are and if suitable resolutions exist has not been explored. Using a mixed methods approach, this PhD seeks to improve and update the CPTED concept by addressing issues of communication and collaboration between CPTED stakeholders, and suggests robust ways of enhancing the social context within CPTED planning. The research answers the following fundamental questions: what are the underlying problems of the CPTED concept and how did they come to fruition; and can the approach to CPTED planning be re-examined and updated to reduce the inherent underlying difficulties and improve the transferability and practical application of CPTED initiatives. The research highlights language and definition inconsistencies in the CPTED framework, transferability and engagement issues between CPTED stakeholders and an unestablished but vital link between CPTED and social sustainability and context. The thesis delivers three major academic contributions to new knowledge. It firmly identifies failings in the CPTED concept since its inception to present; it proposes an updated framework which is theoretically driven, and represents a holistic catchment of all CPTED knowledge; and it makes a solid link between crime prevention and the sustainable development of communities highlighting its importance for context analysis.

A Research Report proposal submitted to the Faculty of Engineering and the Built Environment, University of the Witwatersrand, in partial fulfilment of the requirements for the degree of Masters of Science (Building) Project Management in Construction. Johannesburg 2015 / The construction industry is one of the major industries in the world and has one of the poorest records in Occupation Health and Safety. In developing countries with improved political and economic stability in recent years, infrastructure developments have significantly increased which has implications for the industry to deliver projects safely. Many designers’ in the construction industry in developed countries believe that contractors have knowledge to offer concerning safety as they have the experiences from different projects and can pin point potentially hazardous risks in the design phase of the project and consequently improve on the Health and Safety and Safety Performance of a project. This research aimed to discover what designers’ in the South African construction industry perceived about the use of ECI in the industry and its effect on the safety performance on construction sites. A review of the literature showed that the designers in the construction industry had various perceptions towards trust and commitment of the contractor towards safety and liability issues among other concerns. Twenty-nine questions were identified, which formed the basis of the quantitative analysis that was undertaken. Five hundred architects, engineers and project managers were identified from the Gauteng Province of South Africa and a questionnaire survey emailed to them. A census sample was used in this research and despite the low response rate (9%) from the participants; the data collected was seen as representative of the population. Analysis of the data collected from this survey revealed that designers believe that the use of ECI in the construction industry may improve the safety performance of the project as well as including contractors earlier in the design phase may be beneficial in enhancing safety during construction. The research also revealed that the designers believe that contractors have knowledge to offer in designing for safety as well as identifying potentially hazardous risks that may elude the designers during the design phase. From the data collected, a number of recommendations were developed to promote the use of ECI in developing countries including a review of policies and guidelines in the construction regulations so as to boost the use of ECI and consequently reduce the number of accidents and fatalities in the industry and as well as improve the overall safety performance of construction sites in South Africa. The overall finding of this research show that the designers in the South African construction industry have a positive attitude towards the use of ECI in the construction industry and are ready to implement it mainly due to the fact that it has a positive impact on the health and safety of workers as well as the overall safety performance of construction sites.

In the construction sector today, there is a lot of discussion about material reuse tominimize the negative environmental impact. By reuse of precast concreteelements, significant amounts of CO2 emissions can be prevented. In order toreuse a concrete element for structural purposes in a building, the element need tobe assessed to ensure it can withstand the required loads. This report is based on a comparison of different building codes, it describes andcompares three selected building codes and their associated concrete standardsfrom different eras. The purpose of the report is to compare the results obtainedwhen designing predetermined concrete elements and components. The findingswill indicate whether it is possible to reuse concrete elements that were designedaccording to previous standards. The calculations will demonstrate bothsimilarities and, more importantly, differences in the design approaches of thebuilding codes and how they have evolved. An investigation concludes that by employing a chain of checks, it is possible todetermine if an existing component is reusable considering its load capacity. The differences in reinforcement content vary within approximately 0-25% infavor of the previous code, i.e. the older code requires more reinforcement.
