Abstract

Building activity focuses activity of several people, such as builders, designers, developers, authorities, and beneficiaries. Quality in construction is a main problem faced by them. Quality is a concept defined by experts over time as being: quality is fitness to use, conformance to requirements, quality is everyone’s job, and quality is free. Quality costs, an important factor in decision-making, are divided into four categories: prevention costs, evaluation costs, internal failure costs, and external failure costs. Quality assessment costs represent those costs made in order to check the quality requirements. These include costs of inspection, verification, laboratory testing, clarifications, and so on. The purpose of this paper is to analyze the costs of quality assessment in a project to achieve residential construction.
