Civil and Precast Construction · Question

What does a quotation from a civil contractor usually include and exclude?

Short answer

A civil quotation usually covers labour, materials and equipment for the scope described, such as excavation, concrete, reinforcement, masonry and finishing. It often excludes items like approvals, soil testing, utility connections, taxes, site power and water, and work outside the listed drawings. The exclusions matter as much as the inclusions, so read that part first.

In more detail

Quotations differ in style, from one-page letters to detailed schedules. What they include depends on how the contractor reads the drawings and what it chooses to price. Owners get into trouble when they assume that anything sensible is covered.

Typical inclusions are the work items listed, the grade or class of materials mentioned, supervision, labour, tools and ordinary waste handling. Typical exclusions, which should be written down, tend to cluster in a few areas:

Statutory approvals, fees and testing charges unless named.
Soil investigation and design services, if done by others.
Temporary power, water, storage and site security.
Dewatering, rock excavation or other conditions found only once work starts.
Price changes in key materials after a validity date.
Taxes, which may be quoted extra or inclusive.
Work by other trades such as electrical, plumbing and fire services.

Also check the validity period of the quotation, the payment schedule, the time for completion, how extra work is priced and what rights each side has to stop or change work. These terms sit in the fine print more often than the headline amount.

Read what is missing

If a quote does not say whether scaffolding, shuttering or debris removal is included, assume you may be charged for it until the contractor confirms in writing.

Ask the contractor to list the assumptions behind the price, such as the soil being normal or the site being clear and accessible. If the assumptions are wrong, price movement is usually triggered, and knowing that early lets you plan a contingency.

Compare exclusions across bids as carefully as prices. A lower quote with a long exclusion list can cost more in the end.

Key points

Inclusions follow the drawings and specification the contractor chose to price.
Exclusions commonly cover approvals, testing, utilities, site services and unforeseen ground conditions.
Assumptions and validity period belong in writing and affect final cost.
Ask for clarification in writing before signing, not after work begins.
