Excavation Services in Portland, Oregon
A&N Construction and Excavation provides professional excavation services for residential and commercial projects throughout the Portland, OR metro area. Whether you need a foundation dug, a basement excavated, or a site cleared and graded, we bring the right equipment, local expertise, and attention to detail to get the job done right.
What Are Excavation Services?
Excavation is the process of moving earth — digging, trenching, grading, and removing soil — to prepare a site for construction, install utilities, solve drainage problems, or clear land. It's the first step in almost every construction project, and it needs to be done precisely. Poor excavation leads to foundation problems, drainage issues, and costly rework down the line.
Our excavation services cover the full range of earthmoving work: foundation excavation for new construction, basement and crawlspace dig-outs, utility trenching, site grading, and more. We handle everything from small residential jobs to large commercial site preparation.
Our Excavation Process
- 1
Site Assessment
We visit your property to evaluate soil conditions, access points, grade, and scope of work. We discuss your project goals and identify any potential challenges.
- 2
Utility Locates
Before any digging begins, we coordinate with Oregon 811 to mark all underground utilities. Safety is non-negotiable.
- 3
Permitting
We determine what permits your project requires and handle the application process with the City of Portland or your local jurisdiction.
- 4
Excavation
Our crew arrives with the right equipment for your project. We excavate to the precise specifications required, monitoring grade and depth throughout.
- 5
Hauling & Backfill
Excavated material is hauled off-site or redistributed as needed. If backfill is required, we use the appropriate material and compact it to specification.
- 6
Site Cleanup
We clean up the work area, restore any disturbed landscaping where possible, and leave your property in order.

Excavation Cost in Portland
Excavation costs in Portland depend on the size of the area, depth of dig, soil conditions, access, and hauling distance. Rocky or clay-heavy soil (common in many Portland neighborhoods) can increase costs due to the extra time and equipment required. Small residential jobs like utility trenching typically start at $1,500–$3,000. Mid-size projects like foundation excavation range from $5,000–$15,000. Large commercial site prep can run $20,000 and up. We provide detailed, itemized estimates before work begins.
