Transaction costs incurred by construction owners

Purpose - Transaction costs arise from economic exchange rather than production activities. However, the term "transaction cost" is not consistently defined in the construction industry because the concept of transaction cost is not universally accepted by all stakeholders in construction projects. As a result, empirical studies are few and conflicting because accessing data on transaction costs is problematic, and the interpretation of the data is difficult. The purpose of this paper is to analyze the transaction costs borne by the owner in a construction project from the perspective of transaction cost economics and construction project characteristics.; Design/methodology/approach - A questionnaire survey was administered to construction owners. The factors that impact transaction costs were analyzed in the context of human-related issues (the owner's and the contractor's positions in the transaction), and environment-related issues (the transaction environment, and project management efficiency). Statistical analyses were conducted to compare the transaction costs incurred in the pre- vs post-contract phases of a project relative to the private vs public sector, different project delivery systems, different procurement methods, and different types of contracts.; Originality/value - The primary contribution that this research makes to the body of knowledge is a better understanding of transaction costs incurred by construction owners in the USA. The highest transaction costs are to be expected in the post-contract phase of public projects awarded on a unit price basis, but can be reduced, hence reducing overall project cost.; Findings - The owners surveyed believe that transaction costs may be reduced if the owner and the contractor follow some basic guidelines (e.g. experience in similar projects, prompt payment, good relationship with project participants, no irregularities in bidding, and only few material substitutions and claims), if the project is well-run (e.g. technical competency, strong leadership, prompt decision-making, effective communication, and fair/speedy conflict management), and if the transaction environment is favorable (e.g. fair risk allocation, early contractor involvement, and complete design documents). The findings of the survey also indicate that post-contract transaction costs are much higher than pre-contract transaction costs expressed as percent of project value and that transaction costs are affected by the owner (public vs private), the procurement method, the project delivery system, and the type of contract.
