TOTAL Heritage.

Growing to serve. TOTAL Mechanical, Inc. was established in 1968 by an engineering graduate from Marquette University.  Twenty years later, the Company was purchased by Dennis Braun, who was then a 10-year veteran of TOTAL as a union sheet metal technician.  Under Dennis’ leadership, TOTAL Mechanical has grown to be the largest locally-owned mechanical contractor in southeast Wisconsin and a company highly regarded for quality, technical expertise and absolute customer commitment.  Dennis’ dedication to overall excellence continues to define the Company’s processes and beliefs.


Our 36,000 square foot Corporate Headquarters, offering the latest in fabrication and information technology, was built in 1996.  Unique to the industry, this state-of-the-art facility provides a more “employee-centered” workplace, with comfortable work spaces, a fitness center, dining facility and locker rooms. 1996 also saw the start of our Industrial Division. We’ve expanded our facility numerous times to accommodate our steady growth.


Our growth can be attributed, in part, to the acquisitions that we’ve successfully implemented. In 2002, TOTAL purchased Hampton Plumbing, a third-generation commercial plumbing contractor, expanding our plumbing capabilities. In 2004, TOTAL purchased Wenninger Mechanical Services, significantly enhancing our building automation capabilities. TOTAL purchased Downey Mechanical in 2006, resulting in the introduction of our Fire Protection Division. In 2008, TOTAL acquired Lombard Electric, expanding our electrical capabilities.


Today, we employ over 300 people, and we continue to grow. Not through any inherent desire to be the biggest, but to provide the depth and breadth of talent and services that will provide the most complete and “satisfying” level of service to our customers.

GE Fitness Center

GE Fitness Center

Job Name: GE Fitness Center – Solar Water Heater
Scope of Work: Design-Build
Location: Pewaukee, WI

The following is a summary of equipment installed at this facility:

  • 16 Solar Skies SS-40 panels with a total area of 637.22 ft2
  • 2 260-gal storage tanks
  • HTP drain-back tank
  • Solar controls made by IMC Instruments
Project Summary:GE Healthcare is one of the most environmentally conscious employers in southeast Wisconsin. Through the “ecomagination” initiative, GE is actively pursuing innovative and profitable solutions to environmental problems. Since 2004, the program has resulted in a greater than 22% decrease in greenhouse gas emissions, with the goal of a 25% decrease by 2015. GE has also reduced water usage by over 30% since 2006, surpassing the original goal of a 20% reduction by 2012.[1]

In order to reduce energy usage at their US headquarters in Waukesha, Wisconsin, GE Healthcare’s Global Facilities Manager, Mark Colannanni, initiated a program to augment the employee fitness center’s gas-fired water heaters with a solar hot water system. GE Healthcare’s Project Engineer, Chris Jurik, contracted with Jim Leuzinger of Pewaukee-based TOTAL Mechanical and Aaron Adler of Milwaukee-based Hot Water Products to design and install the system.

Engineers from TOTAL Mechanical designed the system and determined the best location for the solar panels, hot water piping, controls, and related equipment. Representatives from Hot Water Products assisted with the site evaluation, RetScreen software simulation, conceptual design, product procurement and delivery. Mike Westfahl, a Journeyman plumber from TOTAL Mechanical, then installed the system and filled it with Dowfrost, a propylene glycol-based heat transfer fluid that contains food-grade corrosion inhibitors. The system was leak-tested, insulated, valve-tagged, and labeled prior to bringing it on-line.

The system consists of 16 Solar Skies SS-40 panels with a total area of 637.22 ft2, two 260-gal storage tanks, an HTP drain-back tank, and solar controls made by IMC Instruments. It is capable of generating up to 39 kilowatts of energy, which is equal to 116,100 BTU – enough to provide hot water to as many as three homes.


Key opportunities/challenges:

It may seem that a solar water heater would not be as effective in Wisconsin as it would be in a warmer, sunnier climate. However, Wisconsin has as many sunny days as southern Texas, and the efficiency of a solar water heater is not significantly affected by the ambient air temperature. GE’s solar array faces south, at an angle of 43 degrees from horizontal. This maximizes the amount of direct sunlight captured during the winter, when the sun is at its lowest in the sky. In the summer, the energy lost to indirect sun exposure is made up for by the longer periods of daylight.


Benefit to GE Healthcare:

The system is expected to contribute between 20% and 100% of the fitness center’s hot water, with an annual average of 48%. By reducing GE’s dependence on non-renewable energy, the system also insulates GE against rising fossil fuel costs. With an anticipated lifespan of at least 30 years, the system will ultimately save GE nearly $180,000. Over that period, it will have reduced greenhouse gas emissions by 281 tons, which is the equivalent of 648 barrels of crude oil. In addition to the savings realized by reducing natural gas consumption, the solar hot water system also reduces the maintenance requirements of the existing natural gas water heaters. Since the solar system is able to reduce demand on the gas burners, the burners will require less frequent maintenance, and should last longer than if they were to continue as the only source of hot water for the facility.

U.S. Gypsum Mineral Wool Production Facility

U.S. Gypsum Mineral Wool Production Facility

Job Name: United States Gypsum Mineral Wool Production Facility
Scope of Work
:  Dust Collection Installation
:  Red Wing, Minnesota 
 Contractor:  TOTAL Mechanical of Wisconsin, Inc.
Project Hours: Over 12,000 Man Hours; Over 3,500 Sheet Metal and Project Management Hours

The following is a summary of equipment installed at this facility:
  • (4) 60,000 CFM Drum Filters
  • 1/4 inch Abrasive Resistant 400 Ductwork
Project summary:
United States Gypsum Company was incorporated in 1901 to become the first gypsum company with a national scope.  They are a subsidiary of USG Corporation which has numerous locations worldwide.  United States Gypsum Company partnered with TOTAL Mechanical of Wisconsin, Inc. to upgrade their equipment to conform with DNR standards and regulations.
Although TOTAL Mechanical and USG had a previous working relationship in Wisconsin, this Minnesota Mineral Wool Production Facility was the first out-of-state project for the two companies.  Projections called for a three week shutdown, but TOTAL Mechanical was able to pool its resources and propose a plan to complete the project in only eleven days.  This careful planning saved the company ten days of material storage and kept downtime at the plant to a minimum.
Safety was the number one priority of the project and a full time Safety Director was on site during all working hours.  Daily safety meetings were held to ensure proper lifting procedures and to review many additional safety issues for that days’ activities.
The project began with the demolition of USG’s existing four-story dust collection building.  Crews worked around the clock with over twenty-four people per shift.  The next phase of the project included 40, 100 and 265 ton cranes which were brought in on semis and took several days to assemble.  Over 12,000 manhours were spent on the project from start to finish including project management, sheet metal hours, set-up and clean-up.
TOTAL Mechanical overcame the challenge of time and saved money for USG in storage costs and plant shutdown time.  The USG Mineral Wool Production Facility Project was completed on schedule and TOTAL Mechanical hopes to complete many USG projects throughout the country in the future!
