The assessment of building designs considering constructability factors
Abstract
The application of the constructability concept in building designs at the design stage increases the efficiency of projects in terms of time, cost and quality. Many researches on the constructability and its implementation in practice have been conducted in various countries. However, this concept is still novel for construction research and practice in Vietnam. Traditionally, engineers often review project designs by using 2D-CAD drawings. This seems to be a manual, complicated and time-consuming work. The requirement of developing effective constructability assessment tools for projects in Vietnam arises. This paper aims (1) to discuss the current practices of the constructability assessment in Vietnam, (2) to discuss the ability of 4D-BIM model in analyzing the constructability of designs and (3) to identify the factors which may affect the constructability and to propose the procedure for assessing designs considering those factors by using 4D-BIM model. The results of this paper will be considered as the foundation for further researches on the development of a constructability quantitative assessment framework by using 4D-BIM model for projects in Viet Nam.
Keywords: Constructability, BIM, building design, construction, constructability assessment, constructability factor.
