The OAC Meeting - A Complete Guide and Agenda Template

The OAC meeting's objective

The OAC (Owner-Architect-Contractor) meeting is designed to:

• Monitor progress: by evaluating the project's current status against the schedule and budget, necessary adjustments can be coordinated.
• Facilitate clear communication: the meeting provides a platform to align on project goals and inform everyone of updates.
• Resolve issues: issues can be raised and resolved that could otherwise cause budget overruns or project delays.
• Decision-making: based on progress reports and raised issues, the owner, architect, and contractor can make informed decisions on design changes, budget adjustments, or modifications to schedule.

Who participates in an OAC meeting?

Despite the name, an OAC meeting usually involves more stakeholders than just the owner, the architect, and the contractor. Participants can include:

• General Contractor (GC): Typically coordinates meetings, drafts the agenda, and follows up with action items.
• Owner or Owner's Representative: Provides decision-making authority, reviews proposed changes, and makes final decisions on budget, design, and schedule.
• Architect (Design Team): Ensures project execution aligns with plans, reviews and approves submittals, addresses design issues, and updates drawings.
• Engineer: Oversees technical aspects, addresses issues, and ensures construction aligns with design plans and systems.
• Project Engineer: Manages schedule impacts, assigns tasks, and ensures the construction crew has the necessary resources.

The frequency of OAC meetings

The cadence of OAC meetings depends on factors such as the complexity and stage of a project and the preferences of project stakeholders. More complex projects or critical project stages require more frequent meetings.

Project Phase	# of OAC Meetings	Purpose
Initial Planning	Bi-weekly or monthly	Establish project scope, budget, and schedule. Ensure all stakeholders are aligned and aware of their roles and responsibilities.
Design Development	Bi-weekly or weekly	Review and approve design submissions, address issues, and ensure design alignment with project requirements.
Construction	Bi-weekly or weekly	Monitor project progress, address issues and challenges, and ensure construction aligns with the approved design and schedule.
Critical Path Activities	Daily or multiple times per week	Address critical path activities, such as foundation work, structural steel erection, or roofing installation, where any delay impacts the project timeline.
Completion	Monthly or quarterly	Review the project's progress, resolve any outstanding issues, and ensure the project is completed within the agreed-upon budget and timeline.

Preparing for the OAC meeting

Prioritize the following key steps:

1. Review previous OAC meeting minutes and project documentation

Review the minutes from the previous OAC meeting and focus on action items and their status. Examine schedules, budget reports, and change orders to understand the project's current state. As you do this, highlight any issues that need to be covered in the upcoming meeting.

2. Create and distribute a detailed OAC meeting agenda

Draft an agenda based on your review of project documentation. Agenda items typically include critical path activities, budget, submittals, and quality assurance inspections. Share the agenda with meeting participants at least two days in advance to allow enough time to prepare.

3. Prepare visual aids and progress reports

Create visual aids, such as progress photos, updated schedules, budget charts, and 3D renderings. Clear visuals aid comprehension and help the architect or general contractor diagnose and address issues.

4. Designate a minute-taker or use AI software to document the meeting

Nominate someone to draft minutes and follow up after the meeting. Alternatively, use AI meeting minutes software to document discussions and action items. Detailed minutes ensure that projects meet design specifications and help to resolve disputes.

How to run an OAC meeting

Many OAC meetings are held on-site. Some team members may join the meeting remotely via Zoom or Microsoft Teams. The GC or meeting organizer starts by reviewing the distributed agenda to confirm that all key topics are included and correctly prioritized.

OAC Agenda Topics

Next Meeting and Closing Remarks	Confirm the date and time of the next OAC meeting; Debrief key decisions and major points discussed

Following up

After the meeting, ensure that all updates are synchronized across project documentation and communicated to the responsible parties.

1. Distribute the minutes to attendees within 24-48 hours

Prepare the minutes promptly after the meeting and attach relevant documents that were referenced. If you use AI meeting minutes software, minutes will be ready shortly after the meeting ends and already drafted in your firm's template. This minimizes edits required before distribution.

2. Update Project Management Documentation

Update items such as project scope, budget, schedule, and contracts. Prepare change orders outlining descriptions, schedule impacts, and budget implications, and obtain approvals from stakeholders. Project management software should also be updated with new tasks, deadlines, and resource allocations to ensure all team members have access to relevant information.

3. Follow Up on Action Items

Regularly check in with responsible parties to monitor progress and request periodic updates on action items. For issues or ongoing discussions, schedule follow-up meetings to work through bottlenecks.

There is much to keep track of before, during, and after OAC meetings. Use this checklist to make sure nothing falls through the cracks.

7 Expert tips to run an effective OAC meeting

1. Prioritize agenda items. Structure the agenda to address high-impact issues first, when attendees are most alert. Place routine updates towards the end to ensure critical decisions are made even if time runs short.

2. Implement a "parking lot" system. Use a visible "parking lot" list for off-topic comments, topics, or questions that arise during discussions. Log these items to come back to if time permits or to address them offline, to avoid derailing the meeting flow.

3. Use AI meeting software for automatic OAC meeting minutes. Avoid the time-consuming task of manual minute-taking. Use software to automatically draft meeting minutes—including action items—for in-person and online OAC meetings.

4. Rotate meeting facilitation roles. Avoid having the same person, usually the GC, facilitate every meeting. Rotate facilitation duties among team members to encourage new perspectives on running OAC meetings.

5. Use visual aids effectively. Go beyond slideshows by incorporating 3D models, annotated drawings, or augmented reality tools. These visual aids improve understanding and decision-making, particularly for technical discussions.

6. Establish a clear decision-making protocol. Define upfront how decisions will be made (consensus, majority vote, or ultimate authority). This prevents paralysis on contentious issues and reduces delays caused by orders stuck in review mode.

7. Conduct periodic meeting audits. Every quarter, evaluate the effectiveness of your OAC meetings. Survey participants anonymously, analyze time spent versus value gained, and be open to changing the format if it's not serving the project optimally.

Conclusion

OAC meetings are more than routine check-ins; they are essential for steering a construction project to successful completion. As projects become increasingly complex, efficient OAC meetings—and cross-team collaboration in general—become all the more important for successful project delivery.
