How Long Does Excavation Usually Take in Washington County, OR?

When starting a construction project, one of the first questions people ask is: How long will excavation take? The answer depends on several factors, but with the right team, the process can be efficient and hassle-free. At Evolution Contractors, we’re proud to be one of the trusted excavation contractors serving Hillsboro and all of Washington County, OR.

Typical Timelines for Excavation Projects

For most residential excavation projects, the work usually takes 1 to 5 days. This includes site preparation, digging, and hauling away soil or debris. Larger projects, like commercial site work or full-scale land excavation, may take a week or longer depending on the size of the property and the complexity of the work.

For example, a residential excavation project in Hillsboro, OR for a new home foundation might only take two to three days, while preparing a large commercial site in another part of Washington County could take a full week or more.

Factors That Impact Excavation Time

Several key elements affect how long excavation takes:

  • Project Size & Scope – A small trench or driveway prep goes faster than a full building site.

  • Soil Conditions – In Washington County, clay-heavy soil and rocky ground (especially common in parts of Hillsboro) can require extra time and equipment.

  • Weather Conditions – Rainy seasons in the Pacific Northwest can cause soft or unstable soil, delaying excavation.

  • Utility Checks & Permits – Excavation requires calling 811 and sometimes city permits before digging begins.

  • Site Access – If equipment can’t easily reach the property, it may extend the timeline.

Why Professional Excavation Matters

Excavation is more than just digging — it’s about creating a solid, stable foundation that sets the stage for everything else. A skilled residential excavation contractor ensures the site is properly graded, safe, and ready for concrete, utilities, or landscaping. Cutting corners at this stage can lead to drainage problems, uneven foundations, and costly repairs later on.
