The Construction of BIM Application Value System for Residential Buildings' Design Stage in China Based on Traditional DBB Mode

Through statistical data issued by Ministry of Housing and Urban-Rural Development of China, in 2015, China's real estate companies completed construction area of 7,356,930,000 square meters, of which the residential construction area occupied 69.53%. In China, building information modeling (BIM) technology has developed gradually these years. Despite the successful applications of BIM in commercial buildings, tourism buildings, culture and educational buildings and other public buildings, the application of BIM for residential buildings has not gained wide acceptance, which was only limited to residential buildings' underground garages. This project aims to cover this gap by studying the application of BIM on residential buildings' design stage under the commonly used DBB (Design-Bid-Build) mode. Through the investigation and participation of several projects, this paper constructs BIM application value system including specific implementing scheme and delivery forms based on the DBB mode. The system covers the phases of scheme design, preliminary design, construction drawing design and detailed design and involves the professional fields from general layout, municipal facility, landscape, architecture, structure, MEP(Mechanical, Electrical & Plumbing) and refined decoration.
