At O’Connell Development Group, project completion doesn’t mean stepping back—it means stepping up. Our commissioning process ensures that every system, space, and detail performs as intended before occupancy. We take a proactive, developer-led approach to commissioning that guarantees quality, functionality, and readiness from day one.

Ensuring Operational Readiness
We oversee a comprehensive commissioning process that verifies all building systems (mechanical, electrical, plumbing and fire protection) are fully installed, tested, and operating in accordance with project specs, building codes, and end-user needs. Our team coordinates directly with engineers, contractors, and local inspectors to identify issues early and resolve them quickly.
Our commissioning scope includes:
- Coordination of system start-up and performance testing
- Review of installation quality and functional operation
- Building code compliance walk-throughs
- Utility coordination and final inspections
- As-built documentation review and O&M manual collection
Quality Control from Start to Finish
Our commissioning isn’t a one-week process, it’s built into every phase of our construction oversight. Because we’re involved from design through delivery, we know the systems, materials, and performance expectations behind every component of the project. This allows us to verify not only functionality, but also the long-term durability and efficiency of building operations.
We focus on:
- Identifying deficiencies early to prevent costly delays
- Ensuring closeout documents are complete and accurate
- Verifying warranty compliance and service contracts
- Confirming that all systems meet energy performance targets


Final Turnover with Confidence
We don’t consider a project finished until we’re confident it’s ready for occupancy and long-term operation. We deliver thorough training to property managers and ownership teams, ensure warranties and service contracts are in place, and provide support throughout the post-occupancy transition.
Commissioning includes:
- System orientation and training for owners and maintenance staff
- Full documentation package (manuals, warranties, certifications)
- Final inspections and occupancy coordination
- Post-occupancy support and follow-up
Ensuring Readiness from Day One
Our proactive commissioning process guarantees every system and space performs as designed, before occupancy.
