National Register of Historic Places, Complex Environmental Remediation. Completed: 2015

This project was the complete renovation of a 12-story historic building. Scope of work included the conversion of 198 original apartments to 132 unity of which 25% were ADA compliant. During construction only ADA units were vacant and all others were occupied which posed a challenge. Asbestos abatement occurred in occupied units. The phased approach included: Phase 1 - installing new 4-pipe HVAC chases while the existing radiators were being used for heat in occupied apartments. Phase 2 -HVAC/Mechanical- Replaced the air handler and installed the new chiller. Accelerated schedule was met when the new system was operable nine months after notice to proceed (NTP). Phase 3 - Removal of the old radiators so the floor to ceiling windows could be replaced. Insulated fall protection barriers were installed in all apartments as an additional safety feature for residents. Phase 4- Drywall crews followed the window crew, along with cabinet replacement, painting and flooring. Phase 5 - 4Sight converted 33 apartment to be fully accessible. Phase 6 - Top-down approach was utilized once 8 of the 12 stacks of apartment were completed, the last 4 apartments were completed per floor. This approach allowed 4Sight to then paint the corridors and install new carpeting and we worked our way down the building and completing the project on-time. Project was designed using Iowa’s Green Streets requirements to promote public health, energy efficiency, water conservation, smart locations, operational savings and sustainable building practices.
