A “barrier” to constructability is any significant inhibitor that prevents the effective implementation of the constructability program. Barriers exist among owners, designers, and constructors, and can be broken into 4 categories, 1) Cultural Barriers, 2) Procedural Barriers, 3) Awareness Barriers, and 4) Incentive Barriers. Once barriers are identified, they may be mitigated or overcome. Tactics recommended to remove these common barriers are included in the research. Researchers have identified the 18 most common barriers to constructability, including the top 5 common barriers shown below as an example. (SP34-1 V2, p. 17)
- Complacency with status quo
- Reluctance to invest additional money and effort in early project stages
- Limitations of lump-sum competitive contracting
- Lack of construction experience in design organization
- Designers perception that “we do it”
Barrier assessment checklist tools are included as part of the Constructability Implementation Guide, which is described later under the section on Implementation Tools.
