Submittal Tracking with BIM

This blog post was originally written for the Cn3D Construction blog. Cn3D Construction is now a U.S. CAD company, so please check back here at www.uscad.com/blog for more written articles from Jennifer Lanzetti and our new U.S. CAD Utah team.

MEPF Equipment is one of the biggest changes a project undergoes from design intent construction documents to field install shop drawings. Keeping track of the three stages of submittals is critical to proper spatial coordination.

To help in this endeavor, I have developed a 3D submittal tracking process to make sure every light, panel, AHU, pump and so on is tracked properly ensuring that the space designed is adequate to house all the necessary systems.

Three stages of submittals

1. NO SUBMITTAL

When my team first receives a mechanical and electrical model, we add a generic clearance around all of the equipment and place a large X signifying we have not received a submittal on this equipment yet.

2. UNAPPROVED SUBMITTAL

After we’ve received the unapproved copy of the submittal from our client, we adjust the size and clearance on all the equipment in the model and place a large X with the word UNAPPROVED. This signifies that we are close to having the correct equipment in the model, but is subject to change.

3. APPROVED SUBMITTAL

After we’ve received the returned and approved submittal from our client, we remove the X’s from said equipment and are able to move forward with assurance that the coordination is accurate.

As always, we require our clients to review all finished shop drawings and compare with their approved submittals.

This is a big step in the right direction to help the entire team during 3D clashing and coordination. The BIM and MEPF community has made a lot of progress in the virtual planning world; we want to share this advancement as well as hone it to be the best solution possible.
