Our proven and certified staff have the collective experience and skill to help our customers navigate any existing HVAC and plumbing systems' issues.

CUSTOM FABRICATION

United Mechanical construction means fabrication that's efficient and cost-effective.

United Mechanical has made a commitment to pre-fabricate as much of our piping and plumbing systems as possible at our main office campus located in Oklahoma City, OK. In addition, we have committed to pre-assemble ductwork in 12’ – 16’ lengths in our main facility.

By performing this work in a controlled environment out of the construction jobsite, we believe we can maximize our labor force while at the same time meeting tight construction schedules in today’s fast paced world.

Using our shop facilities to pre-fabricate our materials takes advantage of the Trimble System. Our workforce is by far the most efficient in our market.

Our fabrication shops consist of 7,500 square feet of production area for Piping Fabrication and 9,000 square feet of production area for Plumbing Fabrication.

Major equipment housed in our facility includes two (2) pipe welding positioners capable of rolling pipe up to 30” in diameter, four (4) power mig welders, one (1) power roll pipe cutting table and beveling machines for pipe up to 30” in diameter, one (1) roll grooving machine for pipe up to 24” in diameter, overhead bridge crane, chop saw, T-Drill, pneumatic grinders/drills/ratchets and an assortment of jigs used to facilitate fit up and assembly of spools and repetitious items

Our pipe fabrication crew have become very proficient in pre-fabricating the following:

  • mechanical room piping
  • engineer approved equipment skids
  • equipment packages
  • pip risers
  • straight piping runs

We currently pre-fabricate all four plumbing batteries for all restrooms, all plumbing risers and as much of the straight plumbing runs as feasible in the plumbing fab shop. Our goal is to reduce the field labor by as much as 50% which in turn helps maintain the project schedule.

We believe we save labor costs due to using a controlled environment and having equipment and tools readily available for use.

Our sheet metal shop currently consists of 21,000 square feet of production and storage area.

Our shop equipment consists of a

  • Vicon complete coil line system
  • ESAB Plasma cutting and water jet table for cutting flat metal sheets and duct liner
  • Four coil cut to length coil line
  • 90 ton press brake
  • Ten gauge foot shear
  • Spiral duct machine
  • Additional specialty equipment

Our goal is to pre-assemble all ductwork in 12’ – 16’ lengths in order to reduce our jobsite field labor hours, which in turn helps maintain the project schedule.

Transparent Pricing on Quality Commercial Mechanical Construction

Commercial installations and other mechanical construction services range in cost. This is due to the varying nature of the jobs. At United Mechanical Construction, we’re committed to giving you a transparent and cost-effective solution no matter what your project looks like.

Construction projects that have tight deadlines or that call for complicated design and engineering may cost more. Contact us to get more information on our fair and transparent pricing.

When determining the cost of your project, we take several factors into account:

HVAC Equipment

Time

How quickly you need the work done

Safety is key when it comes to working with mechanical systems

One of the ways we deliver quality service and promote everyone’s well-being is by making a commitment to safety. At United Mechanical we believe that creating and maintaining a safe work environment is not only the right thing to do, but also a highly-effective cost saving measure. As a mechanical contractor, the work we do can be dangerous if done without care. With the prudent application of safety measures we eliminate unnecessary costs from accidents, insurance, non-compliance fines, and lost productivity.

It is the belief of the United Mechanical group of companies that both the company and its employees enjoy the benefits of a safe workplace. We are committed to complying with applicable laws and regulation in our pursuit of providing a workplace this as free of accident, injuries and illnesses as possible.

Many benefits will be derived from the follow plan. Among them are:
