Design-construction interface dissonances

Abstract

The thesis reveals results of research study on design and construction interface dissonances in large building projects in the contextual boundaries of Eastern province of Saudi Arabia. To accomplish study objectives, the researcher carried comprehensive literature review of subject through periodicals, dissertations, previous research studies & books written on professional relationships on project interfaces. Initially the researcher carried out a pilot study based on survey questionnaire developed through literature review. Pilot study encircles three large building projects, eventually the validity of tentative questionnaire was evaluated and final questionnaire for survey at macro perspective was organized. Responses from (48) forty eight consultants and contractors were analyzed through statistical analysis tool “STATISTICA”, the results indicate that lack of coordination, insufficient working drawing details, involvement of designer as consultant, involvement of contractor as consultant & participants' honest wrong beliefs are considered as most important origins of professional dissonances on project design and construction interfaces. Whereas the project management as individual professional service, nationality of professional firms & involvement of contractor in design phases are interestingly revealed as least important origins of dissonances between professionals on project design and construction interfaces in large building projects.
