Abstract:
Most design errors are prevalent among construction projects. Traditionally, engineers have to ensure a good coordination between all design systems of the project before construction stage. However, this traditional method is not an effective process because the comparison of designs on different drawings can be easily failed due to the unclear overview of the designs and their coordination with each other. In addition, design errors certainly still occur and this occurrence could negatively affect the cost, schedule and safety performance. For building construction projects in Cambodia, the level of occurrence of those design errors remains unclear. Thus, this study aims to evaluate the percentage occurrence of design errors between structure and other building components such as structural, architectural, mechanical, electrical, and plumbing systems. Comparing with the total number of design errors arising in each building project, the percentage occurrence of design errors is determined by applying the percentage formulas. The results show that design errors between structure and architecture are the most critical problems which frequently occurred among all samplings, followed by design errors between structure and structure.
