HCG Associates Testimonials
February 2017

"Darrel Harris was the structural engineer for my home renovation and complete foundation replacement. He took the time to address my needs in a timely fashion, and was also available and responsive to my contractor’s requests. Darrel helped us build a structure that will truly stand the test of time. His expertise allowed us to combine our designs with the structural integrity and rigidity befitting a 100-year-old Victorian sitting in an earthquake hazard zone. And with that comes great peace of mind."

–Richard Langhammer, Alameda, CA


"HCG Associates played a key role in our seismic retrofit, which has ultimately added value to our property. Darrel's structural engineering plan was excellent and he was very thorough. He worked closely with the City during the permitting process, as well as with the contractor to ensure that our job was completed successfully according to plan." 

–Ted Jarvis, San Francisco, CA


"We recently used Darrel on referral from the contractor to prepare structural plans during a stucco repair to our building. We added earthquake hold downs and replaced an exterior staircase. I found Darrel to be helpful and knowledgeable. He is not afraid to his hands dirty. In fact, the first time I met Darrel face-to-face was when he was on the scaffolding and disappeared into the bowels of the building between floors to check on things."

–Paul Yee, San Francisco, CA


“Darrel is a diligent and responsible project manager. I'm very satisfied with his work. He was very helpful in walking me through all approval processes. I would recommend him to my friends for construction projects.”   

–Vince Tsoi, Orinda, CA


“Darrel Harris and HCG Associates helped my husband and I with our home renovation. He was called in when we hit a snag with the building department and worked fast to get everything in order for us. The project ended up being so much larger than we anticipated and Darrel assisted us every step of the way. Our house is now complete and exactly as lovely as we imagined. We know we never could have done it without Mr. Harris and we are very grateful!” 

–Nicole Benjamin, Sonoma, CA

“My experience with HCG was a positive one. Darrel assisted us most recently with the form for our soft story retrofit. He was prompt in his responses and very helpful. I find HCG to be very knowledgeable and professional. I highly recommend them.”
