Engineers’ Perception of Contract Types’ Performance for Highway Construction Projects

Abstract

This research focuses on the evaluation of a factor analysis of engineers’ perceptions of the performance of highway projects contract types’ (CTs’) against their respective selection criteria (SC) based on the results of a questionnaire survey. The SPSS database’s sample consisted of 91 engineers from Greece and abroad. Patterns of changes in engineers’ assessment of the CTs’ performance were noted and justified by comparing the factors’ content. Apart from the total sample, the analysis considered participants’ subgroups, such as Greek and foreign engineers, and experienced engineers in the private and public sector. Nationality and experience of participants influence the factors’ content. Moreover, a number of criteria tend to cluster together irrespective of CT and engineers’ profile. These pairs of criteria include all uncertainties’ criteria, Scope and Process Uncertainty, Contractual Difficulties and Claims, and finally Value for Money and Criticality of Schedule.
