Built for Project Teams
Mechanical Support for
General Contractors
For GCs who need mechanical scope handled clearly, coordinated early, and executed without unnecessary handholding.
Built for GCs
A Mechanical Sub That Works Like Part of the Team
GCs carry the schedule, the owner relationship, and the trade coordination. When the mechanical sub is reactive, it adds risk to all three. 3rdGen is structured for projects where the mechanical scope needs to be coordinated early, communicated clearly, and executed without slipping into the GC's lap.
- Commercial tenant improvements
- Office, retail, and hospitality buildouts
- Institutional and community facilities
- Existing-building upgrades and retrofits
- Mixed-use and multifamily construction
- Commercial new construction
- High-end residential remodels with complex mechanical scopes
What We Bring
What 3rdGen Brings to Your Project
From the first set of drawings through final closeout, the mechanical scope stays clear, coordinated, and accountable.
Preconstruction Review
Drawings, existing conditions, equipment intent, and budget assumptions reviewed before the mechanical scope is locked in. Conflicts and constraints surfaced early — not in the field.
Scope & Bid Clarity
Clear scope boundaries, inclusions, exclusions, and assumptions so there is no daylight between what was bid and what gets built. RFIs and change orders handled directly.
Field Coordination
Routing, equipment placement, access, and trade sequencing coordinated with the GC, architect, engineer, and other subs. The mechanical scope stays buildable as the project moves.
Installation & Closeout
HVAC scope executed on schedule with attention to sequencing, workmanship, inspection, startup, documentation, punch, and final closeout requirements.
Integration
How We Integrate With Your Team
GCs need a mechanical sub that fits the way they already run projects — not one that requires a different workflow on every job.
Single Point of Contact
A principal stays on the project from scope review through closeout. PMs and supers get answers from someone who actually knows the project — not a relay.
Schedule Discipline
We work to your construction schedule and milestones. Long-lead equipment, submittals, and inspections are flagged early so they do not become the critical-path problem.
Clean Documentation
Submittals, equipment data, as-built information, and closeout packages delivered in the format your owner and inspector actually need.
Coordination
What We Coordinate For
Commercial mechanical work touches architectural intent, structural conditions, electrical, controls, ceiling space, equipment access, and closeout. Our role is to keep all of it on the GC's side of the line — buildable, scheduled, and documented.
- Existing building conditions
- Ceiling space and routing
- Equipment placement and access
- Electrical coordination
- Structural and ceiling constraints
- Trade sequencing
- Schedule pressure and milestones
- Inspection and commissioning
- Controls-ready boundaries
- Punch and closeout

Accountability
Principal-Led, Not Relay-Style
On commercial projects, the costliest problems often begin as missed coordination details. A routing assumption, an equipment location, a controls boundary, or an unclear scope line can quietly create field delays and rework weeks later.
3rdGen stays close to the work from preconstruction through closeout. The GC's PM talks to the same person who walked the project, planned the scope, and is accountable for the install. Fewer hand-offs, fewer surprises.
