Residential and Commercial Excavation | Park City, Utah
Excavation Company in Park City, Utah
Professional Excavation Services for Park City Properties
Dirt work done right
Building in Park City means working with steep grades, rocky ground, tight lots, and a construction season the weather controls. Sierra Excavation is a Park City excavation contractor that handles the dirt work behind residential and commercial projects across Summit County and Wasatch County, from the first cut on a raw lot to the final grade before landscaping begins.
Our crews run modern heavy machinery and bring the kind of precise excavation that mountain lots demand, where a foundation sits ten feet from a property line and an underground utility runs somewhere below. Whether you are a homeowner planning a single project or a builder coordinating a full construction schedule, we show up ready and we communicate.
Our professional excavation services include:
Hillside lots
Residential Excavation in Park City
Most of our residential excavation work happens on hillside lots where elevation change dictates everything. We prepare land for custom homes, additions, garages, and outbuildings, and we handle the grading that turns an unusable slope into a buildable pad.
Residential excavation work includes:
- New home site preparation and pad construction
- Basement excavation and over dig
- Driveway excavation, base prep, and gravel
- Trenching for water, sewer, power, and gas
- Yard regrading and drainage correction
- Removal of stumps, rock, and construction debris
Homeowners who need an excavation service for a one time project get the same attention as a builder running six houses at once.
Built to schedule
Commercial Excavation and New Construction
Sierra Excavation supports general contractors and developers on commercial excavation across Park City and the surrounding area. We work from plans, hold grade, and keep the site moving so the next trade is not waiting on us.
Commercial and new construction excavation covers:
- Mass excavation and site cut work
- Building pad and foundation excavation
- Parking area and access road preparation
- Underground utility trenching and backfill
- Storm drainage and erosion control measures
- Site demolition and haul off
Every construction project runs better when the excavation contractor understands the schedule, not just the scope.
Start clean
Site Preparation and Land Clearing
Site preparation is where a construction project either starts clean or starts behind. We clear land, strip topsoil, remove vegetation and debris, and set the grades so the foundation crew can walk on and go to work.
Site prep and land clearing services include:
- Brush, tree, and stump removal
- Topsoil stripping and stockpiling
- Rough and finish grading
- Rock excavation and removal
- Import and placement of structural fill and gravel
- Erosion control installation
To plan depth
Foundation and Basement Excavation
Foundation excavation leaves no room for guessing. Depth, width, and bearing all have to match the plan, and in Summit County that often means working around rock, groundwater, or a tight setback.
We handle:
- Footing and foundation excavation to plan depth
- Full basement excavation on sloped and level lots
- Backfill and compaction after foundation walls cure
- Foundation drain and gravel placement
- Excavation around existing structures and basements
- Window well and egress excavation
Below grade
Utility Trenching and Underground Utility Work
Trenching is one of the most common calls we get. We install and prepare trenches for water, sewer, electrical, gas, irrigation, and communication lines, and we coordinate locates before any blade touches ground.
Utility trenching services include:
- Underground utility trenching and bedding
- Sewer and water line excavation
- Electrical and conduit trenching
- Irrigation and drain line trenching
- Trench backfill, compaction, and surface restoration
Clear the way
Demolition and Debris Removal
Sometimes the excavation project starts by taking something out. Our demolition services clear the way for new construction and remodels across Park City and Heber City.
Demolition work includes:
- Structure and outbuilding demolition
- Concrete, asphalt, and flatwork removal
- Old foundation and basement removal
- Debris loading, hauling, and disposal
- Site cleanup and rough grade after demolition
Water moves soil
Drainage, Grading, and Erosion Control
Water is the number one thing that damages property in this climate. Snowmelt, spring runoff, and summer storms all move soil if nothing is directing them. We build grade and drainage into every job rather than treating it as an afterthought.
Drainage and erosion control services include:
- Positive grading away from foundations and basements
- French drains, drain lines, and drainage gravel
- Culverts, swales, and detention areas
- Slope stabilization and erosion control
- Runoff management for driveways and access roads
Before the landscaper
Gravel, Landscaping Support, and Finish Work
A landscaping project often needs an excavation contractor before the landscaper ever arrives. We handle the heavy work, then leave the site ready for finish crews.
We assist with:
- Gravel delivery, spreading, and compaction
- Driveway and parking pad base preparation
- Rough and finish grading for lawns and planting areas
- Boulder placement and rock work
- Pond, patio, and hardscape excavation
- Topsoil placement before landscaping begins
Mountain terrain
An Excavating Contractor Built for Park City Terrain
Park City construction comes with challenges you do not see on flat lots: sloped terrain, rocky ground, drainage that has to be planned around snowmelt, and limited access on tight mountain roads. Sierra Excavation plans each job around those conditions and puts skilled operators in the seat, so the excavation protects the land, trees and structures around it.
We coordinate directly with general contractors, architects and project teams so excavation stays aligned with the overall construction schedule, and we focus on clear communication, safety and consistent quality from the first cut to the final grade.
