“…The private sector operators work more from the angle of financial profit maximization, while the public sector thinks in terms of social costs and benefits (Okorafor 2004). In Nigeria, cost and time overruns are given as the most important factors for project abandonment or contractors failure (Elinwa and Joshua 2001); and they are more rampant in the public sector projects. Failure and abandonment of civil engineering projects in public sector have resulted to colossal waste of scarce resources, environmental degradation, unemployment, aggravated deterioration and decay of road and infrastructure, ravaging flood, displacement of homes, destruction of buildings and other settlements etc.…”

Incessant failure and abandonment of public sector projects are still posing serious concern and challenges to the society and other stakeholders in civil engineering and construction industries. The study identifies and examines the salient factors and the warning signals responsible for failure and abandonment of public sector driven civil engineering projects with a view of directing efforts towards forestalling the problems. Opinion survey was adopted with area and judgmental sampling procedures. Primary data based on the identified factors, was captured with the instrument of questionnaire from professionals in civil engineering projects operating in the South East geopolitical zone of Nigeria. The analytical tools used in the study were severity index, spearman's rank correlation coefficient, relative agreement factors and Kendall's coefficient of concordance (W.). The rankings of different professionals were significantly correlated. The result of percentage relative agreement factors indicates that the most salient factors causing failure and abandonment of public sector driven civil engineering projects in order of significance are frequent changes in government and political power, unreliable mode of financing and payment of completed work, and project contract sum indirectly used to compensate political big-wigs etc. Wtest further substantiates the results by indicating significant degree of concordance in opinion of experts. The study therefore concludes that politically-induced corruption, undefined and non compliance to the agreed mode of financing and payment of completed work are the bane of project success. It is therefore a matter of legislation and policy formulation which should be instituted to avert failure and abandonment of public sector-driven civil engineering projects.

“…Lack of material, weather, and physical site conditions, lack of proper tool and equipment, design, drawing and change orders inspection delay, absenteeism, safety, improper plan of work, repetitive work, changing crew size and labour turnover were found to be the most critical factors in Iran (Henry et al 2007). Elinwa and Joshua (2001) also identified mode of financing and payment for completed works, improper planning, and underestimation of time/duration for projects as major factors responsible for timeoverrun in Nigerian construction industry.…”

The study is an assessment of time, cost and quality management in the Nigerian construction industry, and it aims to explore time cost and quality management in the construction industry. The objective of the study is to identify factors affecting time; cost and quality management in building construction projects. This study is limited to the view of a convenient sample of professionals in the building construction industry. The method used to collect data were questionnaire and interview while the data collected were subjected to descriptive statistical analysis using percentage, mean score and frequency. It was observed that planning and scheduling deficiencies, fraudulent practice and kickback and absence of clear Evaluation standards are the major factors affecting time, cost and quality in construction project. The study recommends that construction team should strive to ensure effective management of time, cost and quality in building production. INTRODUCTIONClient when engaging professionals for the purpose of procuring a building or other infrastructure are primarily concerned about quality, time, and cost. Quality being the perceived project outcome based on prescribed production information; time being the expected duration for safe project delivery; and cost being the monetary outcome relating to quality i.e. cost of achieving the quality of a project (Elamah, 2006).Research carried out by Bowen, et al (2007) has shown that most construction project are procured on the basis of only two of these parameters i.e. time and cost. This is understandable since the majority of the project management control systems highlight time and cost, and overlook the relative importance of quality (Hughes, Hillebrandt and Murdock, 2000). Similarly, Herbsman and Ellis (1991) argued that the main problems in traditional approaches to project delivery have been in extensive delays in the planned schedules, cost overruns, serious problems in quality, and an increase in the number of claims and litigation associated with construction projects.In order to plan and manage a successful project, the three project parameters of time, cost and quality should be carefully put into cognizance (Marion 1996). In arguing for the consideration of the three project parameters in attaining client s basic objective, Bowen, et al (2007) propose that the project parameters are the three points of a triangle and that neglecting one factor will have a corresponding detrimental effect upon the other two. In support of this fact, a study conducted by Lansley (1994) argued strongly for the importance of studying the behavioural aspect of management in attempting to address problems facing the construction industry. Bowen, et al (2007) asserted that little evidence exists of successful project where the three project parameters have been balanced and there is a need to embrace time, cost and quality management as a human activity system.

“…Project overruns has a negative effect on infrastructure procurement by raising the capital-output ratio in the sector with a concomitant negative effect on the overall economy. For instance, project overruns of cost and time has been identified as the significant factor responsible for project abandonment and high incidence of contract failure (Rwelamila, Talukhaba and Ngowi, 1999;Elinwa and Buba, 2001).…”

This paper provides conceptual insights on the economic impact of project cost overrun and schedule delays on infrastructure procurement in developing countries with huge infrastructure deficit in Sub-Saharan Africa. Projects cost overruns and schedule delay are a major and widespread problem in infrastructure procurement the world over. It has received a lot of attention in the recent past. However, the literature reveals that extant studies on project overruns are heavily skewed towards causative factors, with little or no attention to the effects it has on the economy as a whole. The paucity of studies on the effects of project cost overrun and schedule delay will further reinforce the imperative to reacquaint policymakers and infrastructure developers, as well as project financiers with the gravity and import of the problem for infrastructural development in particular and the wider economy in general. The study undertakes an exploratory approach drawing from a wide range of secondary information and materials obtained from policy documents, study reports and peer-reviewed articles. The findings show that cost overrun and schedule delay in infrastructure procurement can have a damaging economic effect ranging from allocative inefficiency of scarce resources, further delays, contractual disputes, claims and litigation to project failure and total abandonment. The study recommends project management capacity-building for infrastructure developers, project managers as well as a number of innovative control mechanisms such as reference class forecasting, public-private partnership and computer-aided cost estimating tools including artificial neural networks, data mining, building information modelling as well as fuzzy neural inference model, genetic algorithms, and stochastic simulation to curb the menace of the problem.
