  • Description: Abstract: That the need for Infrastructure in developing nations and particularly Africa has reached a critical point cannot be over-emphasized if the social and economic development needed by the teaming population must be met. Research has suggested some project delivery schemes/ procurement systems for achieving the task. Fall in global oil prices, fluctuating interest and inflations rates, with depletion in government revenues amongst others have made the traditional procurement systems unsustainable for most governments. Hence, the need for alternative sources to be sought. In the past three decades, Public Private Partnership and its variants have been adopted by governments both in the developed and developing nations as means for infrastructure delivery. The experience in some countries is rather nascent when compared to the years of engagement and extent of use of this model. The study uses an exploratory literature review methodology to evaluate the experience of the Nigerian Construction Industry and compare with the experience of some developing nations. This is with the aim of unpacking lessons from the failures or successes of these nations that can strength the current position of the country in its preparedness in using the model or otherwise. The study concludes by outlining some key lessons from other nations either directly or through World Bank Reports. This study provides industry practitioners and policy makers in the country an assessment guide to evaluating its position and working practices in the light of other developing nations.

  • Description: Abstract: Procurement has been identified as the link between a desire by the client for a construction project and the delivery of value products to agreed standards. Thus, it is an arrangement which define contractual processes, funding patterns, risk allocation, work structure and relationship amongst parties on a project. There is sufficient evidence in literature that procurement of public works in developing nations has failed to deliver necessary infrastructure required for economic development of these nations. Particularly in Nigeria, much resources have been committed to the delivery of infrastructure projects but limited benefits have been obtained. This research entails an exploratory qualitative study into the challenges of construction procurement in Nigeria. The study uses an interview of construction industry professionals who were purposively sampled to identify factors mitigating effective construction procurement. Findings from the study show that improper implementation of legislative framework, funding, corruption, hostile operating environment, inadequate knowledge of practitioners of procurement methods and unstable economic environment are factors affecting public procurement in Nigeria. The study concludes that for construction procurement to meet the need of delivering necessary infrastructure for economic development in a nation like Nigeria, intrinsic issues within the national environment have to be handled by relevant stakeholders. Keywords: Construction, Procurement, Developing Nations, Infrastructure, Challenges.

  • Description: M.Tech. , South Africa is one of the countries in the world that has delivered the highest number of houses to the poor through various delivery mechanisms. This was done to fulfill her vision of adequate housing for all, as reflected in the National Housing Policy framework. Over the last fifteen years, the African National Congress [ANC] led government has vigorously ensured that essential services were made available to advance the lives of ordinary people. Since 1994 to date, about 2 700 000 houses have been delivered, providing more than 13 million people with secure homes. One of the housing strategies, as contained in the National Housing Policy of 1994, was to provide subsidy assistance to low income groups to enable them to become home owners and improve their quality of life. The Housing Subsidy Scheme, adopted as the channel of delivery, has to date helped reduce the housing backlog and is tending to reach the goal of eradicating informal settlement by 2014. This research work is an evaluation of the post-occupancy experience of housing subsidy beneficiaries. The study evaluated satisfaction levels of subsidy beneficiaries, what beneficiaries actual do with the subsidized houses after they have been allocated to them, to ascertain if the subsidized houses have improved the beneficiaries’ lives. It also evaluates if the progressive strategy of housing to South Africa citizens is being realised; as well as determining government commitment in maintaining these houses. The methodology used for the study was both qualitative and quantitative. The quantitative research was conducted in four already established housing subsidy locations in Johannesburg, Gauteng Province of South Africa. A structured questionnaire with dichotomous, multiple choice, scaled, matrixtype and open-ended questions was used to conduct interviews and obtain data during the survey. Findings from the study revealed that the progressive strategy of housing is successful in fulfilling its vision to supply adequate housing to all its citizens. However, beneficiaries are not satisfied with the subsidized houses, because of the units’ sizes. Also, defects occurred in the houses delivered. These defects include roof leakages, cracks in walls, lack of finishing internally and externally, and defects in roof trusses. The cause of these defects was a result of poor quality control mechanisms put in place by the Department of Housing. Lastly, it was also revealed that the government has no plans in place to prevent slum conditions in the subsidized housing areas, by means of a well structured maintenance system. Based on the findings from the study, it is recommended that the Department of Housing and administrator of subsidized housing units in Gauteng should conduct a complete and thorough needs analysis of the beneficiaries of a proposed housing subsidy development, it is also recommended that government should provide as wide a choice of housing and tenure options as is reasonably possible. This can be achieved through the rental housing option. It is further recommended that the Gauteng Department of Housing should set up an independent section to carry out monitoring of subsidized houses during construction and formulate an appropriate maintenance culture that will help in encouraging beneficiaries to maintaining the subsidized house. In addition, the Department of Housing should move beyond the progressive realization of the right to adequate housing as contained in the South Africa Constitution, to the use of the housing to improve the lives of the citizens and lastly, the Gauteng Department of Housing should conduct more post-occupancy evaluations of housing subsidy beneficiaries’ experiences. By conducting more POE, the Department of Housing will be well informed of the satisfaction levels of the occupants whether the house is up to standard, if the houses have improved the lives of occupants and what actually they are doing with the houses once they are allocated to them.

  • Description: Abstract: Out of the numerous challenges facing mankind globally, the impact of climate change poses more threat. These impacts include sea-level rise, more frequent floods from heavy rainfall and notably among others, intense droughts. Despite the United Nations anchored events and conferences geared towards tackling climate change, little success has been recorded till date. Biomimicry, a novel science and method that studies nature’s models and then emulates their forms, processes, and strategies offer a sustainable approach to this menace of climate change. It also has the potential to offer efficient alternatives to the human activities that contribute to the depletion and pollution of the environment. Hence, the objective of this paper is to evaluate and present the potential of biomimicry in for climate change mitigation in the built environment. An extant literature review was conducted on biomimicry and its roles in tackling climate change through mitigation and adaptation. The result explores various Biomimetic innovations and applications with their potential to sustainably mitigate the menace of climate change if adopted. This study is expected to refocus human efforts towards biomimicry where it is believed that nature, during its 3.8 billion years of existence has evolved with highly efficient processes and systems, with the potential to produce solutions to the environmental challenges facing mankind, especially climate change.

  • Description: Abstract: Effective and formal stakeholder management process is critical in achieving stakeholder needs and satisfaction, an important project success factor. Developed countries construction industries have embraced stakeholder management as a soft project management skill and consequently developed suitable approaches for improved project delivery though developing countries are yet. Studies have associated project failures to poor stakeholders' performance, the absence of formal stakeholder management process, industry challenges and lack of proper documentation in developing countries such as Ghana. This study identifies, reviews and documents the historical development of stakeholder management process in Ghana as part of a broader study aimed at "developing sustainable stakeholder management framework for construction process in developing countries" for enhanced project success. An exploratory method with the qualitative technique was adopted. A literature review was conducted into stakeholder management practice to explore the trend, influence of historical development and documentation of stakeholder management process in relation to industry challenges using three countries as case studies. This is aimed at documenting and developing sustainable stakeholder management process for developing countries. A descriptive survey was used for analysis and documentation. Findings are that formal documentation of industry practices, procurement challenges, stakeholders role in project failures led to the reviews and stakeholder focused reports which that advocated for collaboration. A trend which has influenced the development of stakeholder management process. In the absence of formal documentation, the study identified and documented stakeholder management historical development trend in Ghana for the development of a stakeholder management framework.

  • Description: Abstract: Flooding has been a global pandemic for the past decade. In Ghana, it has been an annual tragedy occurrence, particularly in the capital city, Accra resulting in loss of lives and property. Regardless of the many suggested solutions in mitigating these floods, Ghana still experience excessive flooding. The study through an exploratory literature review methodology, reports on the challenges faced in addressing flood control strategies in the capital city of Ghana and makes recommendations for implementation. The study revealed that the single dimensional approach to flood management, lack of adequate funding, poor attitude of residence (Ghanaians) towards the environment and sanitation and finally the ad-hoc management solution to flood posed a major challenge in addressing flood situations. It is recommended that a more sustainable strategy for flood management, holistically addressing flood challenges, intensifying education and prompt prediction of flood occurrence and timely and adequate funding for flood management activities would help address flood challenges. The study makes contribution to literature on addressing flood challenges in Accra for consideration by city authorities.

  • Description: D.Phil. (Engineering Management) , One of the greatest challenges faced by the post-1994 South African democratic government is an immense backlog and shortage of housing for poverty-stricken South Africans. Since 1994, the government has embarked on aspiring housing programmes in order to engage in mass delivery of housing, which was done to fulfill the vision of adequate housing for all, as reflected in the South African National Housing Policy Framework. Over the last seventeen years, the programmes have delivered more than 3 million houses to families, who had no proper housing previously, providing more than 13 million people with secure homes; thus ensuring that essential services were made available to advance the lives of ordinary people. This research investigated and modeled subsidised low-income resident’s satisfaction. The primary aim of the research was to model to what extent dwelling unit features, neighbourhood features, building quality, services provided by government, beneficiary participation, needs and expectations predict the occupants’ residential satisfaction, which were classified as the exogenous variables. A conceptual integrated holistic residential satisfaction model was developed based on the theory developed from the literature review and the Delphi Study findings. The Questionnaire Survey was conducted for the purpose of validating the conceptual model. The survey was conducted in three metropolitan municipalities and one district municipality in the Gauteng Province of South Africa. Results from the investigation pertained to three broad areas. The first results related to theory on housing studies. The findings were that the study addressed the lack of theoretical information about which factors are most significant in predicting resident satisfaction in subsidised low-income housing. The findings also revealed the theory that low-income housing occupants’ satisfaction is multi-faceted and that the latent variables thus lead to residential satisfaction outcome variables which could be used for residential satisfaction measurement. The second set of findings relates to the Delphi Study. The findings from this study were that a number of factors (dwelling unit features, neighbourhood features amongst others), considered to be paramount determinants of residential satisfaction in South Africa low-income housing are similar to the determinants in other cultural contexts. Further findings from literature and the Delphi Study indicated that subsidised low-income housing residential satisfaction could be a six-factor model defined by the influence of dwelling unit features...
