Bid exclusions and clarifications: how to write them and make them stick

The SCOPE system

To write them consistently, use the SCOPE system:

• S — State the inclusions clearly, by spec section or system.
• C — Call out exclusions that affect price.
• O — Own your assumptions and clarifications in writing.
• P — Price alternates and allowances for the gray areas.
• E — Enforce them by carrying them into the contract and managing changes.

S — State the inclusions

Start by saying what you are pricing: the drawings and specs by date and revision, addenda received, and the work by division or system. "Price includes all work shown on drawings A-101 through A-402 dated March 3, and specification sections 06 10 00 through 09 91 00, including Addenda 1 and 2."

Listing the document set matters more than it looks. If the architect issues a new drawing set later, you have a clear baseline to price the difference.

C — Call out the exclusions

Exclusions should cover the items that are commonly assumed, often forgotten or genuinely uncertain. Keep them specific: "Excludes rock excavation" is useful; "Excludes anything not shown" is not, and most owners will push back on it.

Common exclusions on building projects

• Permit fees, impact fees, utility company fees and tap fees.
• Testing and special inspections, when the owner is expected to hire the testing agency.
• Rock excavation, unsuitable soils, dewatering and contaminated material removal.
• Hazardous material abatement, such as asbestos or lead.
• Builder's risk insurance, payment and performance bonds, unless requested.
• Owner-furnished equipment, furniture, low-voltage, security and IT cabling.
• Overtime and premium time, unless required by the schedule in the bid documents.
• Design services, engineering of delegated-design items or permit drawings.

Trade-specific exclusions for subcontractors

Subcontractors need their own list. A drywall sub might exclude fire caulking at penetrations made by other trades, blocking for owner equipment and final cleaning. An electrician might exclude fire alarm, low-voltage, utility transformer pads and temporary power beyond a certain point. A concrete sub might exclude winter protection, rebar design and saw cutting of existing slabs.

General contractors should read these exclusions closely during bid leveling. Every item one sub excludes and another includes is a gap that must be priced by someone.

O — Own your assumptions

Assumptions state the conditions that support your number. Typical ones include normal working hours, continuous access to the site, one mobilization per phase, laydown area provided by the owner, utilities available at the property line, and the schedule duration used in your general conditions.

When an assumption turns out false, you have a documented basis for a change. "Price assumes one continuous mobilization for sitework" is what lets you charge for the second mobilization when the owner delays the building permit.

Clarify conflicts in the documents

Drawings and specs often disagree. The spec calls for one product and the drawing notes another; a detail is missing; quantities don't match. You can ask an RFI during the bid, but many conflicts show up late. When they do, write down how you priced it: "Where drawings and specifications conflict on door hardware, price includes hardware per specification section 08 71 00."

Clarifications turn silent guesses into visible decisions. If the owner disagrees, it gets resolved before the contract, not in month four.

Unit prices for unknowns

Some quantities can't be known at bid time: rock, unsuitable soil, rotten framing in a renovation, extra concrete repair. Instead of guessing and padding the bid, include a unit price: "$165 per cubic yard for rock excavation and disposal, measured in place." The owner pays for what is actually found, and you are protected.

P — Price alternates and allowances

Alternates let the owner choose options: an upgraded roof system, a different flooring, an extra parking area. Pricing them separately keeps your base bid competitive and gives the owner flexibility without a later change order argument.

Allowances cover items not yet selected, like lighting fixtures or tile. State what the allowance covers (material only, or material and labor), how overages and savings are handled and whether markup applies. Vague allowances are one of the most common sources of disputes.

Renovations and existing buildings

Renovation work carries the most hidden risk: what is behind the walls, above the ceiling and under the floor. Exclusions and assumptions matter even more here. State that your price assumes existing framing, structure and utilities are in serviceable condition, exclude concealed conditions not visible during the walkthrough and offer unit prices for the most likely surprises, like rotten sheathing, subfloor replacement or undersized electrical service.

Also be clear about code upgrades triggered by the work. When a renovation requires bringing fire protection, accessibility or electrical systems up to current code, someone has to pay for it. If the documents don't show it, exclude it and say you can price it after the building department's review.

Residential jobs need plain language

Homeowners don't read "Division 31" or "concealed conditions." For residential remodels and custom homes, write the same protections in everyday words: "Our price does not include repairing damage we find inside the walls; if we find rot or old wiring, we'll show you photos and a price before we fix it." Plain language gets read, and a homeowner who understood the exclusions is far less likely to feel surprised.

Keep the tone reasonable

A bid with three pages of exclusions can look defensive, and some owners will see it as a contractor planning change orders. Keep the list focused on items that truly affect price or risk, organized by category, and written in neutral language. Owners respect a clear, reasonable scope; they resent a list that seems to exclude everything.

Make your number easy to compare

Owners and GCs compare bids side by side. If your exclusions are clear, the reviewer can see exactly what your number covers and can adjust competitors' numbers for what they left out. Many contractors win negotiated work simply because their bid was the easiest to understand.

During post-bid interviews, walk the owner through your inclusions and exclusions. It shows professionalism and often reveals that the "cheaper" competitor excluded something significant.

E — Enforce: carry them into the contract

This is the step that most often fails. The bid had a perfect exclusions list, but the contract signed three weeks later says the contractor will perform "all work shown or reasonably inferable from the contract documents," with no reference to the bid. When a dispute comes up, the contract controls, and your exclusions are gone.

Before signing, make sure your exclusions, clarifications, assumptions, unit prices and alternates are attached as an exhibit and listed in the contract's order of precedence. If the owner won't accept an exclusion, price the item and adjust the contract sum, but don't let it disappear silently.

Flow them down to your subcontracts

A GC that excluded dewatering in the prime contract must make sure its sitework sub isn't carrying it either, or that the sub's price includes it if the GC is responsible. Compare your prime contract exclusions with every sub's exclusions and close the gaps in writing during buyout.

Use them when changes come

When the owner asks for something excluded, point to the exhibit and submit a change order before doing the work. A short, polite message works: "Per Exhibit C, item 4, rock excavation is excluded. We encountered rock at grid lines C-D; attached is the unit price calculation for approval." Documentation on day one avoids arguments on day ninety.

Review them with the project manager

The estimator writes the exclusions, but the project manager lives with them. Before the bid goes out, spend ten minutes with the person who will run the job and read the list together. Project managers remember the items that cost money on the last job, like temporary heat, dumpster fees or after-hours inspections, and those belong on the list for the next one. A short review now saves a long argument later.

Build a template, then edit it every time

Keep a master list of exclusions, clarifications and assumptions for each type of work you do, organized by division. For each bid, copy the relevant items, delete what doesn't apply and add anything specific to the project. Never send the whole master list unchanged; reviewers can tell, and it weakens the items that matter.

A worked example

A general contractor bid a $3.2 million medical office building. Its bid included a one-page exclusions exhibit: permit and impact fees, special inspections, rock excavation with a unit price of $165 per cubic yard, low-voltage cabling, owner-furnished imaging equipment and winter concrete protection beyond November 15.

The exhibit was attached to the contract. During excavation, the crew found 420 cubic yards of rock, which added $69,300 through the unit price. The permit was issued late, pushing slab pours into December, and winter protection added $38,500 as a change order. Impact fees of $52,000 were paid directly by the owner as planned.

Without the exhibit, those $159,800 would have come out of a projected profit of about $256,000, cutting it by more than half. With it, the project stayed on budget and the owner, who had seen the list at bid time, approved the changes without a dispute.

Checklist before you submit

• Document set and addenda listed by date.
• Inclusions stated by division or system.
• Exclusions focused on items that affect price or risk.
• Assumptions for schedule, access, hours and utilities.
• Clarifications for every conflict you priced one way.
• Unit prices for unknown quantities; alternates and allowances clearly defined.

Clear exclusions and clarifications don't make you harder to hire; they make you easier to trust. For the steps around them, read about bid day scope leveling and buyout and the path from estimate to signed contract.

Frequently asked questions

What should be excluded in a construction bid?

Items that affect price or risk and are often assumed or uncertain, such as permit and impact fees, testing and special inspections, rock excavation and unsuitable soils, hazardous materials, bonds, owner-furnished equipment, low-voltage work and overtime.

How do you make bid exclusions enforceable?

Attach them to the contract as an exhibit and list that exhibit in the contract's order of precedence. Exclusions that stay only in the bid letter are often lost when the contract is signed.
