What Subcontracted Excavation Work Includes on Your Job

We mobilize equipment based on your project schedule, complete the excavation scope outlined in your plans, and coordinate with your site super or project manager for inspections and next-phase readiness. Our operators use GPS grading systems and laser levels to match elevations in your drawings, and we adjust for rock or unsuitable soils as encountered. Flagstaff's volcanic soils and rocky subgrade often require hammers or rippers, which we bring as standard equipment.

When excavation is complete, your site will have a stable building pad at the correct elevation, clean trench lines ready for formwork or pipe, and graded surfaces that direct runoff according to your drainage plan. Your next crew can start work without additional site prep.

We handle material hauling, coordinate utility locates if requested, and keep access routes clear for deliveries and equipment. If your project requires phased excavation or staged grading, we adjust our schedule to match your construction sequence and avoid conflicts with other trades.

Questions General Contractors Ask About Excavation Subcontracting

These questions cover scheduling, coordination, and site-specific concerns that come up when subcontracting excavation work on construction projects.

How do you coordinate with other trades on a multi-phase project?
We follow your construction schedule and communicate directly with your site supervisor to confirm when excavation phases begin and end. If delays occur, we adjust our equipment schedule to match your revised timeline.
What site documents do you need before mobilizing equipment?
We need site plans, grading drawings, utility locate marks, and any geotechnical data noting rock depth or bearing soil requirements. This helps us bring the right equipment and avoid surprises during excavation.
Why is rocky soil common in Flagstaff excavation projects?
Flagstaff sits on volcanic geology with decomposed granite and basalt layers near the surface, so most projects encounter rock that requires hammering or ripping. We plan for it and bring equipment capable of handling hard material without schedule delays.
What happens if excavation reveals unsuitable soil?
We stop work, notify your project manager, and coordinate with your engineer to determine whether the material needs removal or stabilization. We then adjust the excavation scope and proceed once you approve the solution.
How do you handle material disposal or export?
We haul excess material off-site to approved disposal locations or stockpile it per your site plan. You specify what stays and what goes, and we manage trucking and coordination with the dump or fill site.
