How We Think (and Why It Works)


TriStone Group:

Contrarian by design: we don’t “bid first and figure it out later.” We validate scope, sequencing, and constraints early so the field isn’t forced to improvise.

Character + accountability: partners stay involved, decisions are documented, and commitments are owned—not delegated into bureaucracy.

Tech-forward execution: AI-supported analysis helps surface risk earlier, pressure-test assumptions, and keep approvals moving.

What clients value:
clarity, pace, and follow-through.

Owners and multi-site brands choose TriStone when schedule certainty and visibility matter.

When should we bring TriStone into a project?

As early as feasibility or schematic design before timelines and budgets get “locked” on assumptions. We help align scope, permitting path, procurement lead times, and bid strategy so you don’t lose months to plan-check delays or late-stage cost surprises.

Where do you work (and where are you licensed)?

Our primary markets are Los Angeles, CA and Greater Philadelphia, PA. We support schedule-sensitive openings and multi-stakeholder coordination in those regions.

What Type of construction do you handle in Los Angeles and Philadelphia?

TriStone provides general contracting in Los Angeles and Greater Philadelphia for retail, restaurant and multifamily construction, supported by pre-construction and owner’s representation.

How do you price projects: GMP, open-book, or lump sum?

We’re strongest when pricing can be validated early with open-book estimating and scope alignment. If GMP is required, we work backward from a buildable plan and confirmed assumptions so the contract reflects reality, not guesswork.

What types of projects are a best fit?

We’re a strong fit for retail and restaurant build-outs, multifamily work, and schedule-driven commercial projects where coordination and decision speed reduce risk. We primarily deliver in Los Angeles, CA and Greater Philadelphia, PA.
