Case study / General contractor
BIM coordination ownership for a 416-unit apartment development.
ModelMason managed the composite model, clash-detection process, weekly coordination meetings, and issue follow-through for a large multifamily project with two post-tensioned podium levels.
The engagement
One accountable process across structural and MEPFP models.
Mechanical, Electrical, Plumbing, and Fire Protection subcontractors each developed their own models. Those systems also had to be checked against the structural model and the constraints of post-tensioned podium construction before field installation.
The coordination challenge
Bring independently developed trade models into one visible, accountable process.
Without a single coordination owner, the general contractor would have needed to combine models, run tests, prepare reports, lead meetings, assign actions, and repeatedly verify subcontractor updates.
What ModelMason owned
- Combined and maintained the composite coordination model
- Ran clash detection across structural and MEPFP systems
- Prepared clash reports and a weekly issue log
- Led weekly BIM coordination meetings
- Assigned action items to each responsible subcontractor
- Tracked updated models and open issues through closure
The result
Substantially less day-to-day coordination oversight was required from the GC team.
The general contractor retained visibility into status and major decisions while ModelMason managed the composite model, meetings, reporting, assignments, and follow-through. Subcontractors received clear responsibility for required updates, and unresolved issues remained visible before installation.
