Mechanical Design-Build for Commercial, Multifamily, and VRF Projects

Bay Area mechanical design-build HVAC for commercial interiors, tenant improvements, institutional upgrades, VRF and multi-zone systems, multifamily projects, and premium residential remodels. Mechanical scope is coordinated before installation so routing, equipment selection, and field execution align with the GC, design team, and project schedule.

Process

How We Work

A design-build mechanical process built around clear scope, early coordination, and reliable field execution.

  • Drawings reviewed early
  • Coordination before install
  • Startup + closeout support

Built to reduce field conflicts, schedule delays, and preventable rework before installation starts.

  1. 01 Scope Review

    We review drawings, site conditions, schedule, specifications, and mechanical intent before moving into pricing or equipment planning.

  2. 02 Design Input

    We help clarify HVAC system approach, load requirements, equipment placement, routing, access, and coordination risks early.

  3. 03 Coordination

    We coordinate with the GC, architect, engineer, owner, and other trades to reduce clashes, RFIs, and preventable field issues.

  4. 04 Installation

    Our team executes the mechanical scope with attention to sequencing, workmanship, startup, testing, and closeout.

Design-Build Execution

The Same People Responsible for Scope Decisions Stay Close Through Installation.

3rdGen is a mechanical design-build contractor built for complex projects, where early decisions around routing, equipment placement, access, documentation, and coordination can create field problems later if missed.

  • Direct accountability from scope to closeout
  • Scope decisions connected to field execution
  • Built for GC, architect, and engineer coordination

We are built for project teams that need a mechanical partner who can think through the scope, coordinate with the right people, and execute without turning the work into a management burden.

  1. 01 Scope

    Decisions made early stay accountable through install.

    Routing, equipment placement, access, documentation, and coordination risks are reviewed before pricing and field work lock in preventable problems.

  2. 02 Coordination

    The right people stay aligned before installation starts.

    We work with the GC, architect, engineer, and owner to reduce clashes, RFIs, and coordination gaps that show up on complex mechanical scopes.

  3. 03 Field

    The same leadership stays close through execution.

    Design-build execution keeps scope intent connected to sequencing, workmanship, startup, and closeout — with the same team responsible throughout.

Service Area

Mechanical Design-BuildAcross the Bay Area

3rdGen supports commercial interiors, tenant improvements, institutional upgrades, multifamily systems, VRF and multi-zone projects, and high-end residential mechanical scopes across the San Francisco Bay Area — from early coordination through installation.

San Francisco Mechanical Design-Build

Dense urban projects across San Francisco often require early mechanical input on tenant improvements, mixed-use buildouts, hospitality interiors, institutional upgrades, and VRF systems where routing, access, and schedule coordination matter from the start.
