Analysis Of Constructability Practice In Project Delivery Process In The Nigerian Engineering/Construction Industry

ABSTRACT

This study is aimed to investigate and analyze the implementation of constructability in project delivery process in the Nigerian engineering / construction industry using Rivers state as case study area.Data was collected through questionnaire and interview approach. Analysis of data was carried out with the use of SPSS V16.Results of data analysis revealed that although a high percentage of the sampled population are familiar with the term “constructability”,nearly alldo not have corporate constructability implementation manual nor apply formal constructability implementation programs and techniques as obtained in more developed countries. Constructability implementation is therefore neither systematic nor comprehensive in nearly all the firms surveyed. The universal principles of constructability were accepted by the professionals and rated in the order of importance. The most critical was identified as: carry out thorough investigation of site and development of a project plan. Conditions that constrain constructability in the opinion of the professionals were also identified and rated in the order of impact. Spearman rank correlation analysis shows agreement of opinion between different respondent groups in the sampled population. Engineers, project managers and other industry practitioners are enjoined to adopt these principles and findings in their planning, design and construction activities in order to improve overall project performance and achieve best practices in the industry.
