Dry utility coordinated from day one.
Dry utilities coordinated with the site civil package from day one — applications managed, plans stamped, and every franchise utility on the same schedule as the rest of the job.
Dry utility is its own discipline — and Calichi’s role in it is coordination. We sit between the design team, the franchise utilities, and the contractor: managing applications and submittals, producing the joint trench and composite utility plans, and keeping every provider moving on the same schedule. 17 years, 400+ projects, and direct working relationships with every major franchise utility across California, Oregon, and Hawaii.
Every franchise, every rule book.
Joint trench at every scale.
Net-zero campuses, transit-oriented parking structures, mixed-use infill, distribution warehouses. 400+ projects across California, Oregon, and Hawaii — each with a different franchise utility conversation and the same engineering discipline.

Dry utility works best when the design comes from engineers and the install comes from the trades.
Dry utility construction is skilled work. Contractors install the conduit, vaults, and service equipment — they know the crews, the schedule pressure, and the trade sequencing better than anyone. What they often need is a plan that is complete, coordinated, and submittal-ready before the excavator arrives.
That's where Calichi fits. We design the joint trench with the same discipline as site civil: integrated with grading and stormwater, submittal-ready for each franchise utility, stamped by a licensed PE. PG&E Rule 16, Rule 20A/B/C, SCE Rule 15, HECO Rule 21H, Pacific Power WRAP — we handle each tariff from application through approval.
The result is a plan set that developers, architects, and contractors can build from without guessing. Fewer RFIs in the field, fewer re-excavations, and a dry utility package that reaches energization on the same schedule as the rest of the civil work.
