BIM 360 Glue: Updating Models Due to Design Changes

Champion and Pursuit Team 

Steps Involved:

STEP 1: Information received from design team on design changes which require modifications to 3D coordination model

STEP 2: Project Engineer in-charge of the scope of work (may require several engineer’s input). Determine required changes/impact to SB own models based on responded RFI, issued bulletins, etc.

STEP 3: Identify changes/impacts from subcontractors’ models

STEP 4: SB to make changes on critical, affected elements and upload them in Glue in order for subcontractors to use a basis for changes to reduce potential rework.

STEP 5: Establish deadline where all models will be updated to reflect design changes

STEP 6: Subcontractors to make changes to their models accordingly.

STEP 7: Inform subcontractors to continue coordination based on updated models.

Why this step is important:

1. Our internal and subcontractor shop drawings are being produced directly from the 3D coordination effort using 360 Glue

2. If the coordination model is not up-to-date with the latest changes, the shop drawings may not be correct and thus could result in wasted material and schedule delay as corrections are fabricated, shipped to site and installed

3. It ensures that our internal team understands the extent of every change and what is affected

Do's:

1. Make modifications to the background Structural and Architectural files immediately upon receiving a change

2. Notify subcontractors which RFI’s, ASI’s, and other design changes will require their attention and for them to make adjustments to their model

3. Keep track of which design changes require model adjustment and which ones have been posted to the model

Don’ts:

1. Don’t wait until the last minute to make the model changes or the work will be fabricated and the change and cost will increase

2. Don’t allow subcontractors to make “red line” markings on their shop drawings to reflect the change because other subs may need to know the changes other subs are making to adjust their work
