This paper aims to determine the effect of the period of abandonment on the final cost and duration of resuscitated tertiary educational building projects as a basis for enhancing the performance metrics of the projects and improving the availability of facilities in tertiary institutions in Nigeria.
A structured questionnaire was administered on 47 professionals involved in the physical development of construction projects in Osun State public tertiary educational institutions to provide primary data for the study. Secondary data relating to initial and final costs, initial and final completion dates, dates of abandonment, period of abandonment, date of re-award, etc. were obtained from selected resuscitated projects. Data were analyzed using relative significance index and regression analysis.
The most significant effects of project abandonment were found to be disappointment of populace and over-stretching of existing facilities. The study showed a directly proportional and an exponential effect of period of abandonment on percentage cost overrun of resuscitated projects, which were represented by yc = −329.755 + 19.545x and yc = 6.1662e0.0506x, respectively. A linear relationship between period of abandonment and percentage time overrun was represented by yt = 0.467 + 0.816x.
The fact that the regression equations could not be validated because of paucity of data was identified as a limitation of this study.
This study adds to the body of knowledge on abandonment of building projects from a quantitative perspective. Findings have implications for guiding long-term infrastructure development plans in public tertiary educational institutions.
Maximum threshold at which abandoned projects may be resuscitated at an economic cost was established as 16 months. Findings further suggest that the economy of new construction would outweigh resuscitation of abandoned projects beyond this period.
