Oklahoma State Capitol Interior Restoration project in Oklahoma City, Oklahoma, won a “2022 Best Projects” merit award in the “Renovation/Restoration” category.

This project included the interior restoration of 400,000 square feet of the Oklahoma State Capitol building. The project team repaired and replaced the Capitol’s backbone infrastructure, including the MEP and HVAC systems, the addition of a climate control system for the rotunda, and public access and security in the new visitor entrance. The team added fire alarm and sprinkler systems throughout, upgraded public restrooms, and added LED lighting, control systems, and occupancy sensors. They gutted the basement to replace MEP systems and converted the space into a new visitor level.

Manhattan developed a single-move strategy to relocate occupants within the capitol building only once, which avoided multiple moves, eliminating off-site relocations and multiple temporary leasing agreements. Resulting savings was applied to critical repair and restoration of essential infrastructure systems.

As the design-builder, Manhattan Construction Company partnered with Frankfurt Short Bruza Architects-Engineers-Planners, Rosin Preservation, and Stephen Kelley Preservation for this project.


The awards were presented at the ENR Texas & Louisiana Regional Best Project Awards Luncheon Thursday, October 13, 2022, at the InterContinental Houston – Medical Center in Houston, Texas.
