In this session, you will look at Architectural, Engineering, and Construction (AEC) industry project based on a 2D construction contract in Saudi Arabia.
In this session, we'll look at Architectural, Engineering, and Construction (AEC) industry project based on a 2D construction contract in Saudi Arabia. The case study is a healthcare project with Built up area (540,000 m2) with capacity of 650 beds, in addition to 373 Day Case beds. The healthcare facility and research center, contains 6 medical buildings (380,000 m2 divided to Oncology, Dialysis, Cardiology, ICU, and In-Patient Towers) attached together by a 58,000 m2 service tunnel linked to 45,000 m2 with two central utilities plants, a CUP power house, a medical power house, and a medical gases building. Moreover, there is a 90,000 m2 academic and research building.
Traditionally, information such as 2D IFC Design drawings, Bill of Quantities, and Specs that are transferred to owners for the construction phase are unlinked and exist as independent entities. Some of the challenges encountered by General Contractors (GC) during the construction process include interpretation of two dimensional (2D) drawings and information retrieval. Typically, a GC interprets the 2D as-built drawings and develops composite drawings in their mind to corroborate the relationship between 2D elements and coordination between individual system elements. Once the elements are identified and validated, more 2D shop drawings and multiple documents are to be linked to retrieve the required location and other information about the elements. In this process most of the GCs' technical offices' time is spent on non-value added tasks such as developing mental models as well as searching for and validating information. Additionally, the possibility of misinterpretation of 2D design drawings can also cause delays in retrieving the information.
Saudi Binladin Group (SBG) realized that Building Information Modeling (BIM) is seen as an innovation answer to many of the challenges confronting the AEC industry. By the interpretation and model development processing time during the construction phase can be reduced by using 3D models instead of 2D design drawings. Additionally, manual errors in elements' installation at site and the selection of 2D survey of existing conditions at field affects the information retrieval process. This identification selection process can be enhanced by integrating 3D Scan technology with BIM. The integrated 3D Scan and BIM environment called Digital Construction.
The two main challenges of having Design Package defined as 100% 2D IFC documentation are:
- Design constructability and Coordination.
- Material wastes and abortive works.
