Document library

Every document the builder can create. Open What is this? for a short guide.

Proposal / Estimate
Your priced offer for a job, which the client can sign to accept.
What is this?
What it's for
Lays out the scope, line items, price and terms you are offering before any work starts.
Who signs
The client signs to accept; you sign as the contractor.
Who keeps it
Both sides keep a copy. It is your record of what was agreed and at what price.
When
At the very start, after the walkthrough and before scheduling the work.
Tips
Be specific about what is excluded, not just what is included.
Set an expiry date so old pricing does not get accepted months later.
Prime / Construction Agreement
The main construction contract between you and the client.
What is this?
What it's for
Sets out the full deal for a job: scope, contract price, schedule, payments, retainage, changes, warranty and how disputes are handled.
Who signs
The client and the contractor running the job.
Who keeps it
Both parties. Lenders and inspectors may ask to see it.
When
Before work begins, usually after the proposal is accepted.
Tips
Make sure the payment schedule matches how you will actually bill.
Pick the governing state so the right state notices are included.
Subcontract Agreement
Your contract with a subcontractor for part of the job.
What is this?
What it's for
Defines the subcontractor's scope, price, schedule, payment terms, retainage and insurance for their part of the project.
Who signs
The general contractor and the subcontractor.
Who keeps it
Both. The general contractor keeps it with the project file.
When
Before the subcontractor mobilizes on site.
Tips
Get the subcontractor's certificate of insurance before they start.
Line the scope up with your prime contract so nothing falls in a gap.
Change Order
Written approval of a change to scope, price or schedule.
What is this?
What it's for
Records an agreed change to the original contract: what is changing, why, the cost impact and any added or removed days.
Who signs
The client (or general contractor) who approves it and the contractor doing the work.
Who keeps it
Both parties, filed with the original contract.
When
Whenever scope or price changes mid-job, before the changed work is done.
Tips
Get it signed before doing the extra work, not after.
Include the schedule impact even when it is zero days.
Notice to Proceed
Formal go-ahead that sets the official start date.
What is this?
What it's for
Tells the contractor or subcontractor they are authorized to start and fixes the start and completion dates the schedule runs from.
Who signs
The issuing party: the client or general contractor.
Who keeps it
The recipient keeps it; the issuer keeps a copy in the project file.
When
After the contract is signed and permits are in hand, right before work starts.
Tips
Issue it only once site access and permits are actually ready.
Contract deadlines usually count from this date, so get it right.
72-Hour Notice to Cure
Formal 72-hour notice that a subcontractor must fix a default.
What is this?
What it's for
Puts a subcontractor on written notice of a problem (missed work, quality, safety) and gives them 72 hours to start fixing it.
Who signs
The general contractor who issues it.
Who keeps it
The general contractor keeps proof of delivery; the subcontractor receives it.
When

Deliver it the way your subcontract requires and keep proof.

The party billing (here the subcontractor) certifies it.
Who keeps it
Whoever reviews the bill: the general contractor, client, lender or architect.
When
With each monthly pay application, alongside the application for payment.
Tips
Keep the line items the same every month so progress is easy to check.
Bill only for work actually in place or stored as agreed.
