Build vs Buy — Architecture and Engineering
Weigh SaaS subscriptions against a custom build for Architecture and Engineering — see the multi-year total cost of ownership and which path wins.
What this means for Architecture and Engineering
- BIM coordination across architecture, structural, and MEP disciplines drags every project — clash detection cycles that should be hours take days, and the model is always behind the latest design change.
- RFI turnaround averages 8-12 days when the contract requires 5 — every late RFI is a potential change order or schedule claim.
- Submittal review is a black hole — drawings sit on a project engineer's desk for weeks because there is no system to surface what's late or what's blocking.
Where it pays to act
- AI-assisted clash detection and BIM coordination — surface clashes by discipline, prioritize by impact, and draft resolution narratives.
- RFI and submittal triage copilots that pull spec references, drawing locations, and prior similar RFIs to compress reviewer time.
