Impact assessment of change management capability maturity level of contractors on time performance of building projects in Nigeria

Abstract

Changes are generally inevitable in all stages of design and construction of building projects and are commonly associated with some consequences such as time overrun, cost overrun, conflicts and reworks. All these risks contribute to project failure if change implementation is inconsistently managed. In construction, project failure has become a common concern of all parties hence, assessing the impact of capability of con-tractors to manage project changes in order to improve project performance is critical. Therefore, this re-search assesses the relationship between the change management capability maturity level (CMCML) of con-tractors and time performance of building projects. Data collected from respondents via questionnaire survey were analyzed using spearman’s rank correlation, fuzzy synthetic evaluation and multiple regression. The re-search findings reveal that the project time overrun is negatively related to change management capability maturity level of contractor as evidenced by the co-efficient of determination R2 = - 0.385 (i. e as CMCML increases, project time overrun decreases). In addition, the result further indicates a strong negative correla-tion between CMCML and project time overrun going by the spearman’s rank correlation coefficient value of - 0.621 [7]. The established model is capable of predicting contractors’ CMCML thus making it possible to forecast contractor’s likelihood of performance in terms of time.
