The U.S. GSA retained Interactive Resources, Inc. to conduct a water infiltration investigation of the underground parking, leased tenant space, plaza and 9th floor curtain wall at the federal building at 34 Civic Center Plaza in Santa Ana. The structure is nine stories over a basement, constructed of cast-in-place concrete with a pre-cast concrete façade. The granite cobble stone plaza and planters leaked into the underground parking and into the detention cells below. The curtain wall surrounding windows of the ninth floor appeared to be disintegrating due to water intrusion. The federal building houses the U.S. Department of Housing and Urban Development, U.S. Citizenship and Immigration Services, Defense Contract Management Agency, and U.S. Immigration and Customs Enforcement.

Interactive Resources, Inc. prepared a waterproofing feasibility study and construction documents for the repair design and preventative maintenance for the building envelope. Scope of work included a detailed inspection of the entire façade, a survey of existing conditions, specifications and drawings for all needed repairs, and cost estimates.

“The Santa Ana Concrete Facade Restoration Project is very complex and requires a detailed submittal process with product development. Interactive had done an excellent job managing the quality control of the process of color, texture and technical spec to ensure a good match with the existing facade. Interactive and WJE have played active roles in the project for the entire duration. This provided the necessary attention to ensure effective solutions to the many challenges of the project which resulted in successful outcomes. Interactive and WJE did an excellent job complying with all regulatory requirements, including PBS P100, but in particular to OSHA and Safety. The swing stages require OSHA compliance, inspections etc. Interactive has been on top of it for the duration of the project. The complexity and the requirements for proper concrete color and finish for the project were very high. Interactive and WJE researched the existing building materials and provided quality specifications and requirement to ensure the construction contractor delivered a good end product.”
