TL;DR: In this article, a cross-sectional survey of public sector clients in Nigeria was conducted to ascertain the influence of the factors on client satisfaction, and the results proved that the criteria for the selection of consultants can be grouped into service delivery approach, relationship with the client, the caliber of personnel, firm reputation and firm certification.
Abstract: Purpose To receive a satisfactory consultancy service, a construction client must first select suitable consultants. While numerous criteria for the selection of construction consultants have been suggested in the literature, their influence on client satisfaction has hardly been statistically established. This study aimed to reduce the criteria for the selection of construction consultants into a more manageable set of fewer factors and ascertain the influence of the factors on client satisfaction. Design/methodology/approach Data were gathered through a purposively administered cross-sectional survey of public sector clients in Nigeria. Analyzes were done using relative importance index, factor analysis and multiple regression analysis. Findings The results proved that the criteria for the selection of consultants can, in the order of decreasing influence on client satisfaction, be grouped into service delivery approach (SDA), relationship with the client, the caliber of personnel, firm reputation and firm certification. However, SDA is more influential on client satisfaction. All the factors were found to have significant statistical effects on clients’ overall satisfaction with consultancy services. Originality/value The study demonstrates the extent to which construction consultant selection criteria are relevant to client satisfaction. It shows that SDA is the most important predictor of clients’ satisfaction with consultancy services. The results are helpful for grouping consultant selection criteria in future studies, and in guiding clients on the weights to assign to consultant selection criteria during tender evaluation.
