Bridging the Gap between Design and Construction Models to Improve Advanced Work Packaging

• Lack of perception of the 3D model as a deliverable to be used downstream in the project – for fabrication and construction 
• Lack of uniformity in the 3D model attribution 
• Lack of organization on the 3D model by CWP or CWA 
• Lack of consistency between the attribute naming in the 3D model and in other deliverables such as purchase orders
• Lack of pipe spools and field weld determination by the engineering

Too often, the owner, engineering, and construction are poorly aligned on their expectations and goals for the 3D model. The project team needs to outline an AWP model execution plan during the FEP stage of the project, to enable all parties to have a clear understanding of the expectations and goals for 3D modeling: what the model should include, and who has each role and responsibility. The Construction and Fabrication disciplines’ contributions are important to the development of the AWP model execution plan, because their inputs address WFP issues up front.

The following sections represent what, at a minimum, should be included in an AWP model execution plan (FR-TC-01, p. 14):

• Overview
• Project Information and Key Project Contact
• Goals and Uses of the 3D Model
• Roles and Responsibilities
• Collaboration Procedures
• Project Deliverables
• Specific Modeling Requirements
• Naming Conventions
