Condominium Building

11-story landmark property

Location

Denver, CO

Summary

A multi-divisional civil and roofing restoration project at an 11-story landmark property, addressing drainage failures, water infiltration, and roofing deterioration while minimizing tenant disruption.

Challenge

The property faced drainage issues in its parking lot, water infiltration at exterior doors, and a deteriorated roof system. As an occupied building within a historic landmark district, it had complicated access and staging. Seasonal weather constraints further limited available windows for civil and roofing work, requiring scheduling.

Solution

To address the building’s critical exterior issues, DCPS delivered a comprehensive, restoration plan that resolved drainage failures, water infiltration, and roofing deterioration. The DCPS team worked closely with the community’s engineering firm to develop a phased schedule that allowed civil work to be completed in the fall and early winter, with roofing postponed until late spring to accommodate site logistics and seasonal constraints.

The project began with the removal of existing asphalt in the parking lot. The DCPS team regraded and compacted the soil, then installed a new concrete chase drain before repaving the surface to improve drainage.

On upper-level terraces, pavers were removed to clean drainage mats and inspect the waterproofing system. Water testing was performed at multiple exterior doors, and repairs were made following engineering recommendations.

To meet the current rooftop access standards, new safety tie-backs were installed. Then, two material hoists facilitated the removal of the existing double-ballast roof, making way for the installation of a new tapered TPO roofing system with perimeter flashing.

Throughout the project, a phased approach limited parking disruptions and ensured tenant safety and access at all times. The end result provides long-term drainage and roofing improvements while enhancing the safety and functionality of this Denver multi-family building.
