What Goes Into a Commercial Construction Bid (and How to Request One That Gets Accurate Pricing)

Every owner has had the experience of sending the same project to three GCs and getting three wildly different bids back. Usually, the reason is not that one contractor is expensive and another cheap. It is that the three GCs were each pricing a different project — because the information they were given left too much open to interpretation. Accurate pricing starts with the request, not the response.

What a GC needs to price accurately

• A defined scope of work: what is being built, renovated, replaced, or left alone.
• Drawings and specifications sufficient to quantify the scope — architectural, structural, MEP, and any specialty consultants.
• Site conditions and access: how workers and materials enter, where they stage, what other operations are running.
• A realistic schedule with any hard milestones or deadlines called out.
• Owner-furnished items or scopes: FF&E, OS&E, low-voltage, security, and any work handled by other contractors.
• Allowances and assumptions the owner wants the GC to price against where information is incomplete.

Scope clarity is the single largest driver of accurate pricing

"Renovate the lobby" gets a range of numbers. "Renovate the lobby — new flooring per attached spec, new front-desk millwork per attached shop drawing, new lighting per lighting schedule, existing HVAC and ceiling to remain, painting all walls, work to be performed in a two-week window with the property remaining open" gets a bid the GC can actually stand behind. Every gap in scope becomes either an assumption, an allowance, or a change order later.

Drawings — what level is enough?

For small maintenance work, a scope narrative and site walk is often enough. For a full renovation or new construction, GCs need a design set at least at design-development level to quantify materials, and ideally at construction-document level to price with any confidence. Pricing off schematic-level drawings gets you an order-of-magnitude number, not a firm bid — and that is a legitimate output at that stage, as long as the owner knows the pricing will need to be refined as the design matures.

Site conditions and access

A downtown site with a single loading dock shared with a hotel operation prices differently than a suburban site with open lay-down space. An occupied property with resident notification requirements prices differently than a vacant shell. A GC that has not walked the site will make assumptions about access, staging, protection, and phasing that may or may not survive contact with reality. A site walk with all bidding GCs is almost always worth the time.

Schedule

The requested schedule affects price. Compressed schedules require premium labor, more shifts, and larger crews. Extended schedules increase general-conditions cost. Hard deadlines — a brand PIP compliance date, a lease commencement, a seasonal reopening — should be called out explicitly so the GC can price against them rather than assume standard duration.

Cost factors — what actually moves the number

• Scope size and complexity, not just square footage. A 5,000 SF life-safety upgrade can cost more than a 20,000 SF cosmetic refresh.
• Market conditions. Labor and material pricing move; a bid from last year is not this year's number.
• Occupancy. Occupied phasing adds cost across the board.
• Site access and logistics. Constrained access adds real dollars.
• Long-lead items. Anything with a lead time longer than the construction schedule affects price and timing.
• Permit and inspection environment. Some jurisdictions move faster than others; slow ones cost real general-conditions dollars.

How to package a request that gets useful pricing

• Send the same package to every bidder. Different information to different bidders makes the responses non-comparable.
• Include drawings, specifications, and any consultant reports (envelope, structural, environmental) that exist.
• Call out owner-furnished scope and any coordination requirements with other contractors.
• State the schedule, milestones, and any hard deadlines.
• Ask for the bid in a structured format — CSI divisions, line items, allowances, exclusions — so responses are comparable.
• Invite bidders to a site walk if the project is more than a straightforward tenant improvement.
• Allow enough time for a considered response. Bids rushed under too tight a deadline get padded.

Reading the bids you get back

The lowest number is not automatically the winner. Compare the exclusions, allowances, and assumptions as carefully as the base number. A bid that appears low because it excludes half the scope will become the highest bid once the change orders arrive. A bid that appears high but includes clearer scope, more realistic allowances, and a defensible schedule is often the actual best value.
