What foundation excavation involves

Before a foundation can be poured, the ground has to be dug to the shape and depth the plans call for. A footing needs a narrow cut, a crawlspace needs a shallow excavation across the building area, and a basement needs a deep one. The dirt that comes out has to go somewhere, which is why hauling is one of the first items to settle.

Foundation work is tightly sequenced. The dig comes after the pad and clearing, ahead of the forms and concrete, and an inspection has to happen before concrete is placed. Knowing who arranges that inspection, and when, keeps the job from stalling.

When people need a foundation dig

A house, shop or garage is ready to be built on a cleared and leveled pad.
A basement or crawlspace is planned.
A footing is needed for a barn or outbuilding.
An addition needs its own foundation.
A site has been prepared and the plans call for excavation to a set depth.
A building is being replaced on an existing foundation site.

What the work usually looks like

Confirm the plans. The depth and shape of the dig come from the building plans.
Locate utilities. 811 notice comes before digging.
Mark the dig. The foundation outline is marked on the pad.
Dig to depth. The footing, crawlspace or basement is excavated.
Handle the dirt. Dirt is stockpiled, spread or hauled away as the scope states.
Inspection and concrete. The inspection is arranged, then forms and concrete follow.

How to prepare

These points are worth settling before the dig:

Have the building plans and the depth of the dig in hand.
Settle whether the price includes hauling away the dirt.
Settle who arranges the inspection before concrete.
Ask Pend Oreille County whether a permit applies.
Find out who will call 811 and get the ticket number.
Settle how winter work is handled if the dig falls in cold months.
Get the scope and price in writing.

What affects the cost

Excavation is commonly priced by the hour for operator and machine, or as a set price for a defined scope. For a foundation dig, the total depends on the depth, the ground and what happens to the dirt.

Type of foundation. A basement means a deeper and larger dig than a footing or crawlspace.
Hauling. Whether the price includes hauling away the dirt.
Ground conditions. Rock and wet ground slow digging.
Winter. Frozen ground can slow digging.
Access. Distance and winter roads can affect a job.
Preparation. Clearing and pad work done first reduce what the dig has to cover.

Where the dig fits in a building sequence

Foundation excavation sits in the middle of a longer sequence on a rural lot: clearing, the building pad, utility trenches, the foundation dig, the inspection and then forms and concrete. Each step depends on the one before it. A pad that is not finished delays the dig, and a dig that is not inspected delays concrete. Knowing the order, and who is responsible at each step, keeps the whole job moving.

Local rules and sources

Permits and inspection. Whether you need a county permit depends on the project. For land in Pend Oreille County outside city limits, Pend Oreille County's Community Development Department handles building permitting. Inside a city such as Newport, ask the city. An inspection has to happen before concrete, so settle who arranges it.

Utility locates. In Washington, notice must go to the one-number locator service (dial 811) at least two full business days, and no more than ten full business days, before digging starts (RCW 19.122.030). Whoever is digging is responsible for making sure the notice is made, even if someone else makes the call for them.

Registration. Washington contractors are checked on the state Department of Labor & Industries “Verify a Contractor, Tradesperson or Business” page.

Winter. Frozen ground can slow digging in winter.

Common questions

What does foundation excavation include?

Foundation excavation is the dig for a footing, crawlspace or basement, to the shape and depth the building plans call for. Whether the price includes hauling away the dirt, and who arranges the inspection before concrete, are the points that most affect the job. Settle both in writing before work starts.

Is hauling away the dirt included in the price?

Not always. Some foundation prices include hauling away the dirt and others do not, which can make two prices look very different. Ask in writing whether hauling is included, and compare prices only when they cover the same work, including where the dirt goes and how far it travels.

Who arranges the inspection before concrete?

An inspection has to happen before concrete is placed, so settle who arranges it before the dig begins. Ask Pend Oreille County's Community Development Department what inspections apply to your project, and put the answer in the written scope so nobody is waiting on it later.

Does a foundation need a county permit?

Whether you need a county permit depends on the project. Pend Oreille County's Community Development Department handles building permitting outside city limits, so contact it before work starts. Inside a city such as Newport, ask the city. Settle who will handle any permit.

Does winter affect a foundation dig?

Frozen ground can slow digging in winter, and winter roads can affect travel to your lot. Settle how winter work is handled before you agree to a start date, and ask in writing how a delay would affect the price and the order of work, since concrete follows the dig and the inspection.
