PurposeThe increasing pressure from clients and global construction trends have led the construction industry to seek better options for overcoming the emerging challenges and critical issues battling construction projects. The purpose of this paper is to assess the factors affecting the performance of partners in joint ventures construction projects in Nigeria.Design/methodology/approachPrimary data were collected through the administration of questionnaire to partners and consultants who have engaged in joint venture construction project in partnership with the Lagos State Development and Property Corporation. The data obtained were analyzed using Mean Item Score, Wilcoxon‐Mann‐Whitney (U‐test) test, Kruskal‐Wallis (H‐test) test and factor analysis.FindingsThe study revealed that all the factors identified were significant to the performance of partners in joint venture construction with communication, compatibility of objectives and mutual understanding among partners ranked as the most important to the performance of partners in Joint Venture Projects. A KMO value of 0.743 was also derived indicating the suitability of the data for factor analysis.Practical implicationsThe research could be beneficial to potential investors for deciding the factors that contribute significantly to the performance of Partners in Joint Venture Construction Projects for inclusion in the drafting of Joint Venture Agreements. The five groupings from factor analysis and their relationship will also help in developing a framework for Joint Venture Construction Projects.Originality/valueThe extracted factors and values will help to identify prioritized factors which could be used as an assessment tool to evaluate the performance of partners and thus identifying areas for improvement.

Purpose -Management capability is one of the major criteria for evaluating construction contractors during prequalification and tender evaluation This paper aims to investigate the impact of contractors' management capability as a prequalification criterion on cost and time performance of selected building projects. Design/methodology/approach -Prequalification assessments of management capability of wining contractors as well as cost data relating to 77 completed building projects executed between 2004 and 2007 are obtained. The data obtained from a questionnaire and archival data are analyzed using one-way analysis of variance and multiple regression. Findings -The results reveal that contractors' management capability has significant impact on cost and time performance of building projects as evidenced by p-values of 0.042 and 0.039, respectively. Practical implications -The research could be of significant benefit at the research implementation stage of public procurement practice especially in relation to the construction industry in Nigeria. Construction practitioners involved in prequalification and tender evaluation should continue to seek relevant information relating to management capability from the candidate contractors during prequalification and tender evaluation. Originality/value -Models capable of predicting the final cost and duration of building projects are eventually derived based on prequalification assessment of contractors on management capability, proposed contract duration and the initial contract figure. The goodness of fit of the models as defined by the value of R 2 is found to be 96.2 percent and 90.01 percent for cost and time, respectively; thus signifying high predictive efficacy of the models.

Purpose The purpose of this paper is to examine construction bonds, which is a risk management tool for ensuring that projects are delivered successfully, with emphasis on the influence of stakeholders, project characteristics and bonding decision factors. Design/methodology/approach Using case study of completed public building projects, questionnaires were administered on stakeholders that participated in the projects to solicit information on identified issues. Structural equation modelling (SEM) was used to examine relationship among identified factors, and various model selection and validation tests were carried out to arrive at the best-fit model. Findings The final model revealed that type of bond, stakeholders’ influence, project characteristics, risks of bonded projects and bonding decision factors have significant effect on success of bonded construction projects. Of the stakeholders, guarantors and contractors have greater influence on effective administration of bonds. Research limitations/implications The study was limited to Lagos and Ondo states, Nigeria. Data were gathered from clients of public projects, banks and insurance companies (guarantors), as well as contracting, quantity surveying and architectural firms registered with the state governments. This is because of the fact that only such firms can be engaged on projects emanating from the governments. Practical implications To enhance project success, there is a need to adopt construction bond for both public and private projects as against the current practice where it is only mandated for public projects. Originality/value Using SEM, this research examined administration of construction bonds with a view to ascertaining their effects on projects success, thereby providing relevant empirical information for stakeholders for effective administration of construction bond.

Construction projects in Nigeria are generally characterized by cost and time overrun, substandard work, disputes and abandonment; emanating from several factors of which the wrong choice of contractors is a key factor. This study evaluated the criteria adopted by clients and consultants in contractors’ selection in Nigeria. Data were collected with the aid of questionnaire administered on clients and consultants within the Nigerian construction industry. Also prequalification/bid evaluation scores for eighty contractors were collected based on the criteria used in assessing them. The data collected were analysed with the aid of mean score and regression analysis. The result showed that past performance; contractors’ experience; workmanship quality; tender sum; and plant and equipment were the most important criteria for contractors’ prequalification/bid evaluation in Nigeria. A contractors’ selection model was eventually derived based on some of the identified factors. The goodness of fit of the model as defined by the value of r2 was found to be 99%. This therefore implies that only 1% is explained by other independent variables not included in the regression equation; hence the suitability of the model for contractors’ selection in Nigeria.
