Interactive Resources has a long and successful practice of providing historic preservation services. We have designed and overseen the construction of hundreds of historic rehabilitation projects. One such recent project is for the University of California, Berkeley Women’s Faculty Club, designed by architect John Galen Howard and completed in 1923. According to UC Berkeley, it is the only women’s faculty club in the nation with its own building, and was conceived and formed through the initiative of Lucy Ward Stebbins, the second Dean of Women on the Berkeley campus, who began organizing with women faculty in 1919 (at the time, women were not allowed to join the existing Faculty Club). For nearly a century, it has served as an intellectual meeting place, residence and dining facility for faculty and students. Read More

Case Study: BART Waterproofing Project Saves Tens of Millions of Gallons of Drinking Water Annually

From 2011 to 2016, I was project manager for Interactive Resources on a project for BART to repair extensive leaks into the BART Powell Street Station that had plagued BART for decades and had stymied continuous previous repair attempts.

The solution ultimately involved injecting urethane grout through the ceiling of the station into the soil above to create a new waterproofing system to replace, or augment, the original Bentonite system that had failed.

Our investigation revealed a complicating factor that had played a role in both exacerbating some of the leakage as well as thwarting previous attempts to repair it. It turned out that there was an ultra-high temperature steam pipe running the length of the station above the ceiling in the soil above. Despite extensive insulation and encasement in concrete, the heat was raising the temperature of the surrounding soil and could even be felt radiating through the concrete ceiling. The steam pipe was operated by NRG and supplied steam to a number of buildings bordering Market Street. Read More

Who was Frank J. Hagel?

Interactive Resources recently completed a six yearlong project for The Frank Hagel Federal Building in Richmond, California. The main tenant of this six-story structure is the Social Security Administration, and Interactive Resources was retained by the General Services Administration to investigate and report on ongoing water intrusion into the building’s basement from the plaza above. You can read about our feasibility study, final report, schematic design, construction documents and cost estimates here.

We thought it would be interesting to learn about the person whose name is on this building we’ve spent so much time studying. Surprisingly, just googling Frank Hagel doesn’t easily answer this question. Read More

Envelope Study & Improvements for UC Berkeley’s University Hall

University of California, University Hall Envelope Improvements


We recently completed a study for UC Berkeley’s University Hall. This seven-story tower and adjoining two-story annex at the west edge of campus, designed by the well-known west coast firm Welton Becet & Associates and constructed in 1959, originally housed the University of California Office of the President. When UCOP relocated to Oakland, University Hall became home to the campus's Visitor Center and a variety of administrative offices. Read More
