LOCATE TO BACKFILL IN 4 STEPS
Scope & Locate
Walk the route with your PM, confirm KMZ and plans, and coordinate 811 locates and permits.
Pothole & Design Verify
Daylight existing utilities with our vacuum trucks and confirm depths before we mobilize install crews.
Install Conduit & Vaults
Trench, bore, or microtrench the route, set vaults and handholes, and pressure-test every duct.
Restore & Document
Backfill, compact, restore hardscape, and deliver as-builts with depth and location records.
UNDERGROUND CONDUIT & DRY-UTILITY INSTALLS
Underground utility construction is the foundation of every fiber network, small-cell node, and power extension in Arizona. Get the conduit path, depths, and vault placement right and every downstream phase, cable pulling, splicing, energizing, runs cleanly. Get it wrong and the entire build pays the cost. Fampa Construction is a Gilbert-based, AZ-licensed underground utility contractor (ROC #339873, BBB Accredited) building that infrastructure for ISPs, telecom carriers, and utility owners across the Phoenix Metro.
Our crews install HDPE and PVC conduit, single-duct and multi-duct duct banks, precast vaults, handholes, and pull boxes, using HDD, microtrench, or open-cut based on what the route actually needs. Every install is preceded by 811 locates and vacuum potholing from our Peterbilt Guzzler trucks, and every route ships with as-builts and depth records for your GIS and engineering handoff.
From FTTH neighborhood duct banks in the Phoenix metro to long-haul conduit routes across the Phoenix Metro, our underground utility program is engineered around what actually matters on a real build: accurate depths, clean vault sets, protected existing utilities, and documentation you can rely on years after the trench is closed.
