Optimization of Cost and Quality in Oil and Gas Construction sites: A review

Abstract

For a successful project delivery in the oil and gas construction site or in any other clime, the optimal values of cost and quality must meet the expectations of the client. Unfortunately, there have been incessant expectation gaps in most projects. An extensive literature review, traceable to a number of persuaded researchers, of the current project framework has painstakingly revealed, about 70 associated criteria derived as sources of the sustained failure of cost and quality optimization objective. Fundamentally, in construction works, cost overruns as well as quality nonconformity result from a breach of these optimal values and lack of the requisite dynamic intervention strategic planning to restore the balance of the system being delayed or absent. Cost and quality optimization, therefore are anchored on sustainable planning, monitoring and controlling procedures (before, during and after) in all the construction activities regarding manpower, materials, machineries and methods requirements. From works of literature, a hybridized approach that combines a modified composite Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) with the Analytic Hierarchy Process (AHP) is proposed for the objective cost and quality optimization in the oil and gas sector. This preferred method finds credence to the comprehensive criteria weighting factors. Therefore, this proposed validated model should be utilized in future optimization efforts in oil and gas construction as a modified hybrid MCDM algorithm.
