DETAILING CHALLENGES

Coordination across a large resort development.

01

Steel distributed across multiple building areas

The extensive steel package required consistent detailing information across hotel, residential, and shared-use spaces.

02

Different building functions and framing needs

The development brought together guestrooms, residences, event spaces, and hospitality amenities, each with its own structural and coordination requirements.

03

Coordination through model sharing

The model-sharing workflow supported the exchange of updated structural information as detailing progressed across the project.
