I found Dimension by chance when I was passing by an in-progress construction site. The site was immediately next door to a very popular coffee-house/public gathering area. I had noticed the tidiness of the construction site and how courteous the construction crew was to the passers-by. Out of a whim, I approached someone on the site for contact info. By chance, it happened to be the owner, Nick. He was very nice, and gave me a card. A couple months later, I called him for a project on my property that I had been planning for about a year. The project was an underground excavation for an expanded garage under my existing building in addition to new foundation for an in-law (ADU) on my lot. The site access was tricky, the structural work significant and due to the geo-slide conditions in my area, the project was not straightforward. That said, Nick came on site and had a bid to me within weeks. Most of the other contractors I contacted that were hard to nail down for appointments, talked “big” and overbid or simply did not show up. Surely, if you have done any construction, you know what I mean. Dimension, however, was nothing but professional. They came in promptly with a fair and reasonable proposal. We closed the deal and moved forward. Dimension crew showed up on the exact day we agreed upon. The office staff maintained regular communication and expectations were set (and met) throughout. The crew worked extremely disciplined hours. Even during the periods of “wait time” for city inspections, Dimension stayed in regular contact and returned promptly when the site was ready. Resourcing is clearly organized with this company. Dimension stayed on track, both from a schedule and budget standpoint. From a budget standpoint, we were precisely in sync — even with the minor changes that my architect and engineer presented mid-project. No surprises — which is the way it should be. The effort completed successfully. This is my 4th major ($200k+) renovation project, and Dimension is without a doubt, the most organized and carefully orchestrated construction firm I have worked with to-date. My only regret is that I don’t have a new project to offer to them right now.

Dimension’s staff made a complicated project go smoothly and on schedule. The crew was on site when they said they would be, and on task from the moment they arrived each day. I appreciated their responsiveness and flexibility, and was very impressed with the crew foreman, Joel, who is skilled, knowledgeable and was communicative and helpful during the entire project.

Working with contractors in the Bay Area can be challenging and expensive. I can certainly say Dimension made it straightforward to get a fair bid for my construction project and get it done as I expected. Nick, the owner, is knowledgeable and honest. Daniela, at their office, is professional and polite. The exact kind of people I like to work with! Thank you all at Dimension Construction.
