The Project Manager’s Guide to BIM Coordination Milestones

Project managers treating BIM coordination as an ongoing background activity, rather than a scheduled series of milestones, miss the accountability checkpoints that defined milestones would otherwise create.

Why Ad Hoc Coordination Lacks Accountability

BIM coordination performed as a continuous background activity, without specific scheduled checkpoints, can proceed without any clear point at which model maturity or coordination completeness is explicitly verified — making it easy for coordination gaps to persist unnoticed until much later in the project.

Where Milestone-Based Structure Provides Value

Defining specific coordination milestones — tied to model maturity gates and sign-off checkpoints — creates explicit moments where coordination status must be verified and confirmed, rather than assumed to be progressing adequately in the background.

Why This Matters for Schedule Accountability

A project schedule built around explicit coordination milestones can hold the coordination process accountable to specific checkpoints, rather than treating coordination as an amorphous ongoing activity with no clear point at which its progress can be verified against the schedule.

Structuring Coordination Around Clear Milestone Checkpoints

After outlining how defined coordination milestones create schedule accountability that ad hoc coordination lacks, DASH’s Automated BIM Coordination practice is structured around clear milestone checkpoints, providing the accountability that treating coordination as a background activity would otherwise lack.
