DPR Construction

945 Front St, San Francisco, CA 94111 

When it comes to technically complex and sustainable projects, DPR Construction has it all covered. Established in 1990, DPR is a forward-thinking, self-performing general contractor and construction manager with a thick portfolio that ranges from large-scale new construction to small tenant improvements and special projects. 

The company was founded by Doug Woods, Peter Nosler, and Ron Davidowski, hence the name DPR Construction. All three were construction veterans when they started the company, and they were determined to do something different. Doug has over 35 years of technical experience and has served on DPR’s Board of Directors as CEO until his passing in May 2021. As the CEO, he steered strategic planning and took care of customers and employees, earning him and his co-founders the Most-Admired CEO award from the San Francisco Business Times. He was joined by Peter, who now serves on the DPR Foundation board where supports organizations that aid under-resourced youth to gain the skills and perspective needed to guide them to their fullest potential. Last, but definitely not the least, is Ron, who is the ace when it comes to building and maintaining relationships that were instrumental during DPR’s early days and earned them the financial base that DPR needed to start.

Over 30 years later, DPR has become one of the top 3 biggest contractors in the area according to  ENR. The firm has a massive list of recognitions both for its outstanding technical work and the service the company provides. These awards include the 2020 AIA Design Excellence Award, the 2020 Bentley Systems Infrastructure Award, the 2020 DBIA National Design-Build Award, the 2020 ENR Mid-Atlantic Best Projects, the 2020 USGBC Innovation Award for New Construction for the Commercial category, and the firm is also on ENR’s 2021 list of Top 400 Contractors.

During its time in the business, it also serviced big-name clients such as eBay and its great work has been featured in publications like Washington Business Journal, BD+C Giants, and The Washington Post. DPR’s commitment to building resilient and efficient structures can be seen in many of its projects, including the Net-Zero Energy San Francisco Regional Office featured here. The goal was to create a healthy environment that respects DPR’s employees, customers, partners, vendors, and the community at large. The new office space supported Net Zero Energy through daylighting, natural ventilation, and daylight harvesting in the urban setting. On top of that, the very working area itself honors the DPR culture and brand with the way it’s designed to feel “alive” — as a creative space should.
