Start a ProjectWho We Are
Construction management with a builder’s mindset.
Keystone is a San Francisco–based construction management firm founded on a simple observation: too few CMs have actually built. Our team comes from general contracting, bringing practical field experience to every decision — from precise estimating and bid leveling to scheduling and closeout.
We work onsite, not behind a screen — partnering with owners, architects, and contractors to deliver projects that hit budget, schedule, and standard.
What We Do
Our Services
Landlord & Owner Representation
We represent the owner’s interests across every facet of the construction process — protecting budget, schedule, and building requirements from day one.
Preconstruction Services
From bid leveling to value engineering, we evaluate pricing and schedule to keep costs competitive — partnering with contractors to maximize value.
Programming & Development
Research and decision-making that defines scope before design begins — setting the priorities that launch a successful project.
Cost Management
We know your target value. We keep the project on financial track without sacrificing design or function.
