Every estimating assumption, in writing

We hand you the RFI log with the bid. The fastest way to lose an owner is a change order they could have seen coming.

How we bid
· Updated September 2026 · Apex Contracting Group

An RFI log is the list of every question, unknown and assumption an estimator ran into while pricing a job, with the answer the bid was built on. Apex attaches it to every bid, so an owner can see exactly what the number includes, what it assumes and where it could move before signing anything.

Why most change orders start at the bid

Most change orders are not surprises on site. They are assumptions made quietly during estimating: a deck assumed sound, a quantity taken off drawings that do not match the building, a working-hours restriction nobody asked about. When those assumptions are buried in a lump sum, the owner finds out about them as a change order. When they are written down, the owner can answer them before the contract is signed, or at least decide which risks to carry.

The estimator walks the property first

We do not price from photos or a scope sheet alone. An Apex estimator walks the property before the number is written: measuring, confirming access and staging, looking at the conditions the drawings do not show, and noting what can only be known once work starts. Anything the walk cannot settle goes into the RFI log rather than into a contingency you cannot see.

What the RFI log contains

  • Every assumption. Quantities, existing conditions, access, working hours, phasing and anything else the price depends on.
  • Every open question. Items that need an answer from the owner, the engineer or the property team, and what we priced in the meantime.
  • The answer, once it arrives. The log is kept current through award, so the final contract reflects the answers rather than the original guesses.

Line items, not a lump sum

The bid itself is broken into line items that follow the way the work is built: mobilization and protection, each scope of work, and the general conditions and fee shown separately. That makes it possible to compare our number against another contractor’s line by line, and to see immediately where two bids are pricing different things.

Unit prices for the unknowns

Some conditions cannot be known until the work is opened up: rotted sheathing under a roof, damaged framing behind a balcony, wet insulation. Instead of hiding these in an allowance, the bid carries agreed unit prices for them (per square foot, per sheet, per location). If the condition is found, it is paid at the rate you already approved. If it is not, you do not pay for it. Unit prices are agreed before anything changes, so the number you approve is the number you pay.

Alternates and exclusions, stated plainly

Owner-elected upgrades are priced as alternates, separate from the base scope, so you can take them or leave them without re-bidding. Exclusions are listed in writing. If a common item such as permits, utility disconnects or interior protection is not in the number, the bid says so.

How to level bids from several contractors

  • Same scope, same spec. Confirm each bid names the same systems, materials and warranty.
  • Ask every bidder our RFI questions. The log is a ready-made list of what each contractor should have answered.
  • Compare unit prices, not only totals. A low total with no unit prices usually means the unknowns will come back as change orders.
  • Read the exclusions. The cheapest bid is often the one that leaves the most out.

For a standard scope with the site walk done, a conforming bid and the RFI log typically come back in five to ten business days. Larger capital programs take longer, and we give you the date up front.

FAQ

Common questions

What is an RFI log in a construction bid?
An RFI (request for information) log lists the questions, unknowns and assumptions an estimator found while pricing a job, and the answer each part of the bid is based on. Attached to the bid, it shows the owner what the price includes and where it could change, so those items can be settled before the contract is signed.
Why does Apex use unit prices instead of allowances?
Allowances hide the cost of unknown conditions in a lump amount that is spent whether or not the condition exists. Unit prices set a rate in advance, such as per square foot of deck replacement, so the owner pays only for what is actually found, at a price already agreed.
How long does an Apex bid take?
For a standard scope with the site walk done, a conforming bid and the RFI log typically come back in five to ten business days. Larger capital programs take longer, and Apex gives the date up front.
How do I compare bids from different contractors?
Make sure each bid prices the same scope, specification and warranty, compare line items and unit prices rather than only totals, and read the exclusions. Asking every bidder the same questions from an RFI log shows quickly which differences are real and which are gaps.
