ASE bids and builds mechanical work from other people's drawings every year — plan and spec packages, renovations, equipment replacements, and process installations, as a subcontractor to a general contractor or direct to an owner. Most of it happens in buildings that cannot stop: manufacturing floors, operating laboratories, schools in session, recreation centers with water in the pool.
We estimate and execute mechanical scope from an engineer's construction documents: HVAC, hydronics, exhaust, and mechanical piping, with submittals, RFIs, coordination, and closeout run the way a GC expects them to be run.
Rooftop and air handler changeouts, boiler and chiller replacements, VAV and reheat retrofits, and full mechanical fit-outs — including the demolition, structural coordination, and crane work that comes with them.
Welded steel and 316 stainless piping, refrigeration piping, hydronic and process distribution, ductwork and specialty sheet metal. Fabrication and welding are self-performed, so the craftsmanship is ours to stand behind.
Process cooling plants, compressed air, distilled water, dust collection to ATEX and NFPA standards, and utility connections to production and test equipment in manufacturing environments.
ISO-class cleanroom mechanical, laboratory HVAC, pressurization and containment, and the TAB, startup, and certification support that gets a space accepted — built new or renovated inside a room that is already classified.
Revit modeling and clash detection, existing-conditions models of live buildings, cloud construction documentation in Bluebeam Revu or Procore, real-time schedules shared by read-only link, and commissioning responsibilities defined before construction starts.
ASE has worked as the design-build mechanical subcontractor to Mortenson on manufacturing and office renovations, and as a competitively bid mechanical contractor on plan and spec projects. Our engineering capability is there to make your package go smoothly: we read the design intent quickly, and we raise problems early enough that they get solved on paper.
| Estimating | Complete, legible scope letters that state what is included and what is not, so the bid you carry is the bid you get. Progressive pricing from ROM through GMP on negotiated work. |
|---|---|
| Coordination | Revit modeling and clash detection with the other trades, and existing-conditions models when the drawings do not match the building. Conflicts get resolved in coordination, not in the field. |
| Constructability | Having engineering staff on the contractor side means conflicts, long-lead equipment, and access problems get flagged early — as a clear RFI your engineer can resolve on their drawings, well before it becomes a field change. |
| Shutdown planning | Integrated Work Plans for every task and Method of Procedure documents to the facility at least 7 days before any utility-affecting work. Weekend and off-hours changeouts when production cannot stop. |
| Schedule | Real-time schedules shared by read-only link, weekly OAC participation, and our standing rule: bad news does not get better with time. You will hear about a slip from us before you see it. |
| Field execution | Journeyman technicians and craftspeople, self-performed piping and sheet metal, rigging and aerial lift certification, and OSHA/MSHA qualifications with Veriforce compliance support for industrial sites. |
| Closeout | TAB, startup, controls checkout, commissioning, and certification responsibilities assigned before construction begins — then executed, documented, and turned over. |

| Plan & spec | Competitively bid mechanical scope from a design engineer's construction documents, as a subcontractor to a general contractor or direct to an owner. |
|---|---|
| Design-assist | You keep your engineer. We join early to price options, check constructability, model existing conditions, and identify long-lead equipment while the design is still moving. |
| Design-build | When a project benefits from a single mechanical partner, ASE combines engineering and construction into one line of responsibility from concept through certification. |
| Owner-direct | Prime contracts with facility owners on renovations, equipment replacement, and process work — frequently starting from an existing service relationship. |
