01 — Services

Four scopes,
one contractor.

Every project starts with a scope and a budget. We deliver the four service lines below as separate engagements or as one contract, depending on how far up the design work has been taken.

01

Commercial build-outs

Interior construction for tenant space: demolition, framing, mechanical, electrical, and plumbing coordination, and finishes.

02

Design-build

Design and construction under a single contract, so drawings, budget, and field conditions are resolved by one team.

03

Renovations

Reconfiguration and upgrade of existing commercial interiors, from a partial refit to a full interior rebuild.

04

Project management

Budget, schedule, procurement, submittals, and site supervision managed on the owner's behalf.

02 — Process

From bid
to closeout.

Every job runs through the same four stages. You know what happens next, who is doing it, and what it costs before the work starts.

  1. 01

    Preconstruction

    We review the drawings and scope, walk the space, and return a bid with assumptions and alternates written out.

  2. 02

    Mobilization

    Permits, subcontractor awards, and long-lead materials are lined up before crews arrive on site.

  3. 03

    Construction

    Trades are sequenced and supervised through the build, with inspections scheduled as the work completes.

  4. 04

    Closeout

    Punch list, final inspections, and handover of the finished space to your team.

03 — Approach

A project is only as good as its coordination.

Build-outs and design-build work both come down to sequencing: the right trades on site in the right order, submittals moving, and changes handled before they reach the schedule. That is the part we own.

  • Procurement Subcontractor scopes are leveled against the bid and awarded before mobilization.
  • Submittals Product data, shop drawings, and field questions tracked in a single log.
  • Site supervision Supervision through construction, coordinating trades and inspections.
  • Cost and schedule Progress, cost, and schedule updated as the job moves.
