Roof-Level Fall Protection Systems
General Motor Corporation – Renaissance Center

Project Scope
Hired to bring the General Motor’s Renaissance Center in compliance with
OSHA requirements, Hines turned to NTH expertise for design of fall
protection systems for several roofs not originally built to sustain OSHA-required fall arrest forces. In addition to this challenging design component, we were asked to:
  • Assess the integrity of the structure to resist the associated loads
  • Perform full-scale load tests to verify capacity
  • Provide consulting/inspection services necessary during the project’s installation phase

Project Approach
To develop a viable design for these complex roof conditions, NTH:
  • Considered the anticipated use of the various roofs (i.e. podium level skylight roofs, high/ low-rise elevator shaft roofs, hotel lobby/restaurant roofs, and penthouse roofs)
  • Evaluated the existing conditions
  • Developed conceptual designs
  • Load-tested various building components for support

Project Results
NTH delivered a creative design to spread the loads without requiring
major structural strengthening of the building.

This innovative solution allowed work to continue with minimal
interruption to current occupants and provided our client with significant
cost savings in the installation phase of the project.
