Mechanical

Mechanical services are a cornerstone of LMC’s capabilities, allowing us to deliver high-quality industrial solutions with the strength, flexibility, and self-perform expertise clients depend on.

Our fabrication facility gives us greater control over quality, scheduling, and execution, helping keep projects efficient, organized, and consistent from start to finish. 

From fabrication through final installation, our experienced teams deliver the skill and reliability needed to execute complex scopes.

What an industrial mechanical contractor self-performs

Self-perform is the difference between a schedule you control and a schedule your subcontractors control. These are the scopes our own crews carry out, not ones we broker:

• Hydro and pneumatic testing, so system verification does not wait on a third party
• Torquing and tensioning to documented values on flanged and bolted connections
• Tubing and instrumentation, installed with the piping rather than after it
• Mechanical detailing, so shop drawings come from the people doing the work
• Painting and coating, applied in-house by NACE certified painters and blasters

The markets we build mechanical scopes for

Our mechanical work concentrates where process piping and rotating equipment carry the risk:

• Compressor stations for oil and gas, and metering and regulating stations
• Power generation stations and data centers, including modular data center skids
• Environmentally sensitive piping
• Launcher and receiver installation, and valve modifications
• Food manufacturing facilities
• Modular piping skids, carbon and stainless steel piping, and water infrastructure piping

Why the fabrication shop matters to a mechanical bid

Work that moves off the job site and into a controlled shop is work that stops competing with weather, congestion and other trades. Our Dansville facility runs to 700,000 square feet of covered space across 88 acres, and it is served directly by the Rochester and Southern short line railroad, so large fabrications leave by rail rather than being cut down to fit a truck.

The equipment is the reason we can hold that promise: a PythonX CNC plasma cutting system, a Ficep Gemini plate processor, Ficep Gemini HPE, CNC tube benders, and sub arc and automated welders. Modular skids are assembled, tested and coated before they ship, which shortens the field scope to setting and tying in.

Certifications a mechanical contractor should be able to name

Ask any industrial mechanical contractor to list their endorsements before you shortlist them. Ours are:

• ASME “U”, “S” and “PP” stamps, and NBIC “R” for repairs
• API 1104 for pipeline welding
• AWS D1.1 and D1.5 structural and bridge welding
• AISC Fracture Critical and AISC Bridge Fabricator, Advanced
• DOT certified in New York, North Carolina, Pennsylvania and Massachusetts

The trades we keep on staff

LMC employs more than 350 people. That headcount is the point: API 1104, ASME, AISC and AWS certified welders and fabricators, NACE certified painters and blasters, licensed and NCCCO trained crane operators and riggers, millwrights, carpenters, an HVAC service group, engineering staff, and locomotive employees through our American Motive Power affiliation.

Millwright work is worth calling out. Precision alignment, machinery setting and rotating equipment installation sit inside our own workforce, so a mechanical package that includes millwright scope does not need a second contractor mobilised to the same site.

Millwright services inside the mechanical scope

Millwright services cover precision alignment, machinery setting and the installation of rotating equipment, and they are usually the scope that arrives last and holds up commissioning. Because our millwrights are employees rather than a subcontracted crew, that work is sequenced against the piping and steel rather than booked around someone else’s calendar. Laser alignment, grouting, setting to tolerance and coupling work happen with the same crew that installed the surrounding system.

The certifications behind this are public standards, not marketing language. Pipeline welding follows API 1104, pressure equipment carries ASME stamps, structural and bridge welding follows AWS D1.1 and D1.5, and crane operators are certified through NCCCO. You can verify every one of them.

How to choose an industrial mechanical contractor

Three questions separate contractors on a complex mechanical package.

What do you actually self-perform? A contractor who subcontracts testing, coating and instrumentation is coordinating three schedules you cannot see. Ask for the list, as we have published ours above.

Where does fabrication happen? Shop capacity, and whether it is owned or rented, decides how much risk stays out of the field.

Which endorsements do you hold, by name? Stamps and certifications are verifiable. Vague claims about quality are not.
