Commercial GC Project Management: Procore, AIA Billing, Lien Waivers, and Closeout
The most successful commercial general contractors win work on relationships and reputation, but they build that reputation through operational excellence on every project. Delivering on time, managing change orders proactively, maintaining airtight documentation, and closing out projects completely are the behaviors that generate repeat work and referrals. This guide covers the full operational lifecycle of a commercial construction project — from the preconstruction kickoff meeting through final closeout documentation.

Procore for Daily Project Operations
Procore is the operational backbone of a well-run commercial GC project. Used consistently, it creates a real-time, contemporaneous record of every material event on a project — which is your strongest protection in any dispute and your clearest communication tool with the owner and architect.
Daily Logs: The superintendent or project manager completes a daily log every working day. At minimum, it includes: date, weather, trades on site (and headcount), work performed, inspections completed, and any notable events (injuries, deliveries, visitor access, work stoppages). Procore's daily log is time-stamped and cannot be retroactively altered — it is a legal document.
RFIs (Requests for Information): When the field identifies a conflict, gap, or ambiguity in the drawings or specifications, a formal RFI is submitted through Procore to the architect. The architect has a contractual period to respond (typically 7–14 days per A201). Procore tracks open vs. closed RFIs and ball-in-court status. Unanswered RFIs can be the basis for schedule delay claims — your documentation matters.
Submittals: Shop drawings, product data, and samples must be submitted to the architect for review before materials are fabricated or installed. Procore's submittal log tracks submission date, review period, and approval status. Rejected submittals require resubmission — track these carefully as they affect your procurement schedule.
Meetings: Use Procore's meeting module (or a consistent template in SharePoint) to document every OAC (Owner-Architect-Contractor) meeting with attendance, discussion topics, decisions made, and action items with owners and due dates.
AIA G702/G703 Billing: The Monthly Payment Cycle
AIA G702 (Application for Payment) and G703 (Continuation Sheet) are the standard forms for monthly billing on commercial construction projects. Most commercial owners and construction lenders require these forms, and they are built around the Schedule of Values — a breakdown of the contract into line items that you update each month as work progresses.
Schedule of Values (SOV): Created at project startup, the SOV breaks your contract into line items (typically 15–50 line items for a TI project). Each line has a description, the total budget amount, a percent complete, and a current billing amount. The SOV should be organized logically by CSI division or major work area so the owner and architect can easily verify the percentages.
Front-loading the SOV: It is common practice (and legitimate) to assign slightly higher dollar values to early work items (mobilization, demolition, rough framing) and slightly lower values to late work items (punch list, closeout). This improves early cash flow. However, most lenders and sophisticated owners scrutinize front-loaded SOVs — do not be so aggressive that it triggers a dispute.
Retainage tracking: Your G702 must show the cumulative retainage withheld. Track retainage separately in your accounting system — it is a receivable, not revenue. When retainage is released (typically at substantial completion), bill it on a separate G702.
Lien releases: Many owners require a conditional lien waiver from you (and sometimes from your subs) before releasing each monthly payment. Keep a lien waiver template that matches your state's statutory form.
Lien Waiver Management
Mechanic's lien law gives contractors and subcontractors the right to record a lien against the project property if they are not paid. Managing lien waivers — the documents that waive this right in exchange for payment — is a critical operational discipline for any commercial GC.
Types of lien waivers: - Conditional waiver on progress payment: Waives lien rights through a specific date, but only becomes effective when payment clears. Use this when signing waivers before payment is received. - Unconditional waiver on progress payment: Permanently waives lien rights through a specific date, regardless of whether payment clears. Use only after confirming payment receipt. - Conditional waiver on final payment: Final lien waiver for the full project, conditional on receipt of final payment. - Unconditional waiver on final payment: Permanently waives all lien rights on the project.
Sub lien waiver management: Collect conditional lien waivers from your subs before you release their payment. Issue your own conditional waiver to the owner before you receive each monthly draw. When payment clears, exchange conditional for unconditional waivers. Track this in a waiver log — missing sub waivers expose you to lien claims even after the owner has paid you.
Subcontractor Management: The GC's Core Competency
Managing 10–20 subcontractors simultaneously — coordinating their schedules, managing their change orders, reviewing their invoices, and maintaining quality — is the core operational competency of a commercial GC.
Subcontract execution: Execute a written subcontract with every sub before they mobilize. Use AIA A401 (Subcontract Agreement) or a well-drafted custom subcontract reviewed by a construction attorney. The subcontract must flow down the relevant provisions of the prime contract — if the owner can terminate for convenience, your sub agreement should mirror that right.
Schedule coordination: Hold a weekly subcontractor coordination meeting on every active project. Review the two-week lookahead schedule, identify any conflicts or access issues, and confirm material lead times for upcoming work. Document attendance and decisions in meeting minutes.
Invoice review: Review every sub invoice against the approved schedule of values and actual work in place. Do not approve invoices for work not performed or materials not on site. Overbilling by subs is common — especially on lump sum subcontracts for work that appears visually complete but may have incomplete rough-in.
Change order management for subs: When scope changes, issue a formal subcontract change order before additional work proceeds whenever possible. On fast-moving TI projects, verbal authorizations happen — document them immediately with a written change direction letter and follow up with a formal change order.
Change Order Management: Protecting Your Margin
Change orders are the primary mechanism by which commercial GCs protect (or erode) their project margin. Every scope change that is not captured in a formal change order is margin you are giving away.
Change order process: 1. Identify: A potential change in scope is identified from an owner request, RFI response, unforeseen condition, or design revision. Create a Potential Change Order (PCO) in Procore immediately. 2. Price: Obtain pricing from affected subcontractors, add your own costs (project manager time, general conditions impact), apply your overhead and fee, and prepare the change order proposal. 3. Submit: Submit the change order proposal to the owner in writing. Note the cost impact and any schedule impact in a separate time extension request if applicable. 4. Negotiate and Execute: Negotiate with the owner to reach agreement. Do not proceed with changed work until you have written authorization — even on fast-moving TI projects, a written email authorization is better than verbal. 5. Flow down: Execute a corresponding change order with the affected sub before they perform the extra work.
Maintain a running change order log showing all approved, pending, and disputed changes. Share a summary with the owner monthly so there are no surprises at the end of the project.
Project Closeout: O&Ms, As-Builts, and Warranties
A professional closeout is how you earn the final payment, release of retainage, and a strong reference for the next project. Closeout is also where many GCs lose money — dragging out the process, failing to collect closeout documents from subs, and missing final punch list items delays retainage release by months.
Closeout document checklist: - As-built drawings: Marked-up plans showing any field deviations from the original design (relocated outlets, resized ductwork, revised partition layouts). Collect as-builts from each sub for their scope before demobilization. - Operations and Maintenance (O&M) manuals: Equipment operation manuals, maintenance schedules, filter change instructions, and equipment warranty cards for all mechanical, electrical, and plumbing systems. Organize in binders by CSI division and deliver to the owner at substantial completion. - Warranties: Collect all manufacturer and subcontractor warranties before final payment. Your prime contract warranty (typically 1 year for general construction defects per A201) starts at substantial completion. - Certificate of Occupancy (CO) / Final Inspection: The building department's final inspection and CO is the official end of the construction phase. Deliver a copy to the owner. - Final lien waivers: Collect unconditional final lien waivers from every sub. Do not release your own unconditional final waiver to the owner until you have received your final payment. - Training: For projects with complex mechanical or electrical systems, schedule equipment training sessions for the owner's facilities staff before turnover.
Start closeout activities at 50% project completion — not at 95%. Pre-ordering training sessions, collecting warranty cards as equipment is installed, and preparing as-builts in real time rather than reconstructing them at the end saves weeks of closeout time.

FREQUENTLY ASKED QUESTIONS
When should I start collecting closeout documents from subcontractors?
Start at 50% project completion. Require subs to submit O&M manuals, warranty documentation, and as-built markups as a condition of their second-to-last progress payment. Waiting until the end of the project means chasing subs who have already moved on to other jobs — and delays your retainage release by weeks or months.
What happens if a subcontractor files a mechanic's lien on my project?
A sub lien can trigger the owner to withhold payment from you or activate a lien bond requirement. Respond immediately: review whether the claim has merit, communicate with the sub to resolve the underlying payment dispute, and consult a construction attorney. Prevention is far better than cure — maintain current lien waivers from every sub on every payment cycle.
How do I handle a change in scope that the owner claims is already included in the contract?
Document everything. Issue a formal RFI asking for written clarification of whether the work is in scope. If the owner insists it is in scope, proceed under protest — in writing — stating that you are performing the work to avoid delay while reserving your right to claim the cost. Do not simply absorb ambiguous scope changes without documenting your position.
What is the Schedule of Values and why does it matter?
The Schedule of Values (SOV) is the breakdown of your contract into line items that drives your monthly billing. A well-prepared SOV with logical line items and accurate percent-complete updates makes your billings easy for the architect to approve. A poorly organized or front-loaded SOV triggers architect scrutiny, billing disputes, and delayed payment approval.
