Executive Summary
Delivering a Full-Scale Fitness Facility Built for Performance
KLM Construction served as General Contractor for the 30,000-square-foot buildout of Gold’s Gym Thornton in Colorado.
This tenant improvement project transformed the space into a full-service fitness facility featuring locker rooms, posing rooms, saunas, turf training areas, and expansive cardio and weightlifting zones.
As part of a larger brand portfolio, the facility required strict adherence to franchise standards and disciplined execution within a multi-tenant building environment.
This case study demonstrates KLM’s ability to execute complex, occupied renovations at scale.

The Challenge
Construction Above an Occupied Tenant with Hard Deadlines
Key constraints included:
- Six-month fixed schedule
- Construction in a building with an occupied tenant below
- Strict franchise brand standards
- Utility coordination requiring gas line upsizing
While the gym space itself was unoccupied, the active business below required careful planning to avoid disruption.
Upsizing the gas line required ongoing coordination with local utility providers, adding complexity to scheduling.
