// LESSONS FROM OSCO Construction Group
Embedding MEP into precast panels off-site can eliminate the on-site connection bottleneck that eats schedule gains from prefab.
The first two to three modular projects are a learning curve, not a cost saving — operators must budget for that.
Modular construction is not categorically cheaper; its competitive advantage is schedule compression and revenue acceleration, especially in commercial hospitality.
A Marriott hotel done in 15 months versus 2 years means guests (and revenue) arrive 9 months earlier — quantify schedule benefit in revenue, not just time.
GCs hiring modular manufacturers face a 50% deposit exposure with limited bonding protection; this financial risk must be priced into project financing before committing.
Using a university research centre as a low-risk test bed for AR/VR and other unproven technologies avoids the $20-30k hardware gamble while generating real operational insight.
