Present DayCore Values
We do what we say. Every project, every crew, every day — our reputation is the product.
GPS-grade technology and experienced crews produce tolerances that protect schedules and downstream trades.
Three generations means we think long-term. Relationships built in 1977 are still active today.
We're an extension of your team — not a vendor. GC relationships average 15+ years.
Underground and earthwork done right the first time means no callbacks, no change orders, no surprises.
We invest in technology so our clients don't carry the risk of outdated methods and survey delays.
Our Leadership
Built the company from a single crew in 1977 into a multi-county civil contractor trusted by the Bay Area's leading developers — through consistent work and an unwavering standard.
Expanded services into wet utilities and grew the geographic footprint through the 1990s and 2000s. Established the long-term relationships that still define the business today.
Leading construction management services and technology integration — GPS earthmoving, stakeless grading, and digital project coordination. The next chapter of a 47-year story.
I've known the Trinchero family for over two decades. Their operation runs with a level of professionalism and precision that you just don't find everywhere. They're the first call I make on any civil package.
