OAC Meeting: Agenda, Roles and Minutes

The owner, the architect and the contractor in one room, usually once a week. Done well, it's where problems get decided. Done badly, it's an hour of status updates.

An OAC meeting is a regular Owner–Architect–Contractor meeting held during construction. It is where the three main parties review progress, schedule, cost, quality and safety, and make decisions on open items such as RFIs, submittals and change orders. It is usually held weekly or every two weeks, on site or online.

Who attends an OAC meeting

Who chairs the meeting and who writes the minutes depends on the contract. Often the contractor or the architect does both. Agree it at the pre-construction meeting.

Standard OAC meeting agenda

  1. Safety: incidents, near misses and upcoming high-risk work.
  2. Review of last minutes: confirm or correct, then go through open action items.
  3. Progress and schedule: work done since the last meeting, look-ahead for the next few weeks, critical path status and any delays.
  4. RFIs: open requests for information, who owes the answer and by when.
  5. Submittals: status of shop drawings and samples, especially any holding up procurement.
  6. Change orders and cost: pending change requests, approved changes, allowance status.
  7. Quality: inspection results, open non-conformances, deviations found on site.
  8. Pay application: status of the current payment application (often monthly).
  9. Owner items: owner-supplied equipment, permits, decisions the owner owes.
  10. New business and next meeting.

OAC meeting minutes template

Good minutes are a log of decisions and actions, not a transcript. Each item should carry a number that stays the same from meeting to meeting until it closes.

Also record: date, location, attendees and their company, distribution list, and a line asking attendees to report corrections within a set number of days. Minutes that nobody corrects often become the accepted record of what was agreed.

How to run a better OAC meeting

Common OAC meeting mistakes

Where SpatialSense fits

SpatialSense gives an OAC meeting a shared view of the site. Captures from a 360° walk or a scan are dated, so the progress and quality items on the agenda can be shown rather than described. The owner and architect can open the same view in a browser from their own office.

Progress records

Dated scans and walks become the progress record on their own. Construction progress tracking →

Frequently asked questions

What does OAC stand for in construction?

OAC stands for Owner, Architect, Contractor, the three main parties to a building project. An OAC meeting brings them together during construction.

How often are OAC meetings held?

Usually weekly or every two weeks during construction. Frequency is often set in the contract or agreed at the pre-construction meeting, and may increase near handover.

Who runs the OAC meeting and writes the minutes?

It depends on the contract. Often the contractor or the architect chairs the meeting and issues the minutes. Agree it at the start of the project.

What is the difference between an OAC meeting and a subcontractor coordination meeting?

The OAC meeting is between the owner, design team and general contractor and covers decisions, cost and overall progress. Subcontractor coordination meetings are run by the contractor with the trades and deal with day-to-day sequencing on site.

What should be in OAC meeting minutes?

Date, attendees, and a numbered log of items with the discussion or decision, the person responsible, the due date and the status. Items keep their number until they close.

How can I show site progress in an OAC meeting?

Use dated visual evidence: photos, 360° walks or scans of the same areas from two dates. Showing the two side by side answers progress questions faster than a verbal update.

Bring the site to the meeting. Start a free trial and share your first dated site walk with the owner and architect.
