8.3 Project Documentation & Closeout

Key Takeaways

  • A daily log is the contractor's contemporaneous record of site activity and is the best defense in a dispute or claim
  • A change order is a written amendment to the contract that modifies scope, price, or time; it must be signed by all parties before the changed work begins
  • A certificate of occupancy (CO) is issued by the building department after final inspections confirm code compliance, allowing the owner to occupy the building
  • Before final payment, the GC should collect unconditional final lien waivers from every subcontractor and supplier to protect the owner from subordinate liens
  • Under A.R.S. § 33-993, a mechanics' lien must be recorded within 120 days after completion; foreclosure must follow within 6 months of recording (with a lis pendens in the same window per § 12-1191)

Daily Logs and Field Documentation

A daily log (or daily report) is the contractor's contemporaneous record of site activity. A well-kept daily log is the best defense in a dispute, claim, or disciplinary complaint because it establishes what happened, when, and who was present. Each entry should record:

  • Date, weather, and temperature
  • Workers present (by trade and count)
  • Subcontractors on site and work performed
  • Equipment on site
  • Deliveries received
  • Inspections held and results
  • Problems, delays, and visitors
  • Safety topics discussed (toolbox talks)

Quick Answer: Project closeout is the formal process of completing and handing over the project through a punch list, final inspection, certificate of occupancy, lien waivers, retainage release, and final payment.

Daily logs should be factual, signed, and retained for the project's duration plus any warranty period. Contemporaneous entries carry far more weight in a dispute than after-the-fact reconstruction.

Change Orders

A change order is a written amendment to the contract that modifies scope, price, or time. Change orders can originate from owner requests, unforeseen site conditions, design errors, or RFI responses. The essential documentation chain is:

  1. Change order request or proposal — describes the changed work and why it is needed
  2. Cost and schedule impact analysis — including a CPM float analysis showing whether the change affects the critical path
  3. Written approval by the owner (and architect if the contract requires) before the changed work begins
  4. Executed change order signed by all parties — becomes part of the contract documents

Verbal change orders are risky — Arizona law favors written contracts and modifications. Document the cost and schedule impact of every change, even if it appears minor, because undocumented changes become disputes at closeout.

Pay Applications

Progress payments are typically made monthly based on the schedule of values and the percent complete for each line item. A standard application for payment includes:

ComponentPurpose
Schedule of valuesBreaks the contract into billable line items
Summary of work completedPercent complete by line, this period and to date
Stored materialsMaterials on site or stored but not yet installed
RetainagePercentage withheld (commonly 10%) until completion
Approved change ordersIncorporated into the current billing
Lien waiversConditional waiver on progress payment, releasing lien rights for amounts paid

Retainage is the percentage of each progress payment that the owner withholds until the project is substantially complete. Retainage protects the owner against incomplete or defective work and gives the contractor an incentive to finish. At closeout, accumulated retainage is released — typically half at substantial completion and the balance at final acceptance, subject to contract terms.

Project Closeout

Project closeout is the formal process of completing and handing over the project to the owner. A typical closeout sequence:

StepAction
1Punch list walkthrough — owner, architect, and GC inspect and list every defective or incomplete item
2Correct punch list items — responsible subs correct defects; GC verifies each correction
3Final inspections — building department confirms code compliance
4Certificate of occupancy (CO) — building department issues the CO, allowing the owner to legally occupy
5Substantial completion — architect certifies the work is sufficiently complete for owner use
6Lien waivers — collect final unconditional waivers from all subs and suppliers
7Closeout documents — warranties, operation and maintenance manuals, as-built drawings, maintenance data
8Retainage release — final retainage paid to subs after punch list correction and lien waivers are received
9Final payment — owner pays the remaining contract amount less any agreed deductions
10Notice of completion — recorded in the county recorder's office to establish the completion date for lien deadlines

Lien Waivers and the Notice of Completion

A lien waiver is a document in which a contractor or subcontractor relinquishes mechanics' lien rights for work performed up to a stated date or for a stated payment. Two common forms:

  • Conditional waiver on progress payment — effective only when the payment actually clears; safest for the contractor
  • Unconditional final waiver — releases all lien rights for the project; the GC should collect these from every sub and supplier before releasing final payment to them

Before final payment, the GC should collect unconditional final waivers from every sub and supplier. Otherwise the owner could face a mechanics' lien from an unpaid sub even after paying the GC in full — and the owner may look to the GC's payment bond or license bond for recovery.

Under A.R.S. § 33-993, a mechanics' lien must be recorded in the county recorder's office within 120 days after completion of the project. Recording a notice of completion in the county recorder's office establishes the date of completion and starts the 120-day clock for potential claimants to record a lien. Foreclosure on a recorded lien must follow within 6 months of the recording date (with a lis pendens recorded in that same window per § 12-1191).

Final Payment and Retainage Release

Final payment is the owner's last payment under the contract, typically equal to the remaining balance plus released retainage less any agreed deductions for incomplete or defective items. The GC should not release subs' retainage until all of the following are in hand:

  • Signed punch list showing all items corrected
  • Certificate of occupancy issued
  • Final unconditional lien waivers from every sub and supplier
  • Warranties, manuals, and as-built drawings delivered to the owner
  • Owner's written acceptance of the project

Releasing retainage before lien waivers are collected exposes the GC to double payment — the sub gets its retainage, but if the sub's suppliers are unpaid, those suppliers can still record a lien against the owner's property, and the owner may back-charge the GC.
