Mechanical Engineering Services

Elevate your construction projects to an entirely new level.

With Gausman & Moore, you will work with an industry-leading mechanical engineering firm that is qualified and motivated to help you achieve a successful project outcome. The Gausman & Moore approach you will experience has a proven track record, whether you’re an architect, building owner, design/build contractor, or attorney/insurer.


Who We Work With

Architects: Architects rely on our services to provide a complete building design package if a project is being bid using the Design/Bid/Build project delivery method. Sometimes architects will design the general construction of the building and deliver the mechanical systems using a Design/Build method. “Bridging” or design assist documents may be provided to help the architect better define the mechanical systems that the contractor will provide. Ventilation systems impact the health and safety of occupants and so for commercial buildings plans need to be certified by a registered engineer.

Building Owners: Gausman & Moore’s mechanical engineers help architects with the calculations/energy modeling that helps them comply with energy codes and meet certifications processes like LEED or B3 SB2030. When working directly for building owners we may assess the operations or remaining useable life of the mechanical equipment and make recommendations for replacement or improvements.

Design/Build Contractor: When working for a design/build contractor we may do a preliminary design to assist them in bidding, producing certified construction documents, or creating Revit as-built documents.

Attorneys/Insurance Companies: When working for attorneys/insurance companies we call the work “forensic” because it is usually in the context of a lawsuit or claim. As an industry expert we help to determine the technical aspects of the problem; what wasn’t designed to Code, what broke or failed, etc.


Our Work May Be Unseen, But It Is Very Much Felt

We have only one goal for every project we work on: success. Our mechanical engineers are adept at designing systems to provide heating, ventilating, cooling and plumbing in buildings of all sizes. Whether you have a large or small budget, you can feel confident that our team will proactively collaborate with you to produce a fully functioning system that features high levels of comfort, control, quiet, and efficiency. And that translates into a successful project.

Comfort and Intelligence in Your Projects
Occupant comfort is a top priority and we also design high quality systems to meet the expectations of the owner and architect. We work smartly, too: Making systems more energy and water efficient is in Gausman & Moore’s DNA. Services include:

  • Energy modeling

  • Complying with third party independent systems (LEED)

  • In-house commissioning, which is encouraged to all clients on all projects

  • Delivering projects more efficiently by using Revit and our Mechanical Productivity Pack

When working with architects, we always attempt to minimize the impact of elements of our systems that are visible. This includes louvers on the building’s exterior, or grilles/louvers in aesthetically sensitive spaces. We want the architect’s work to shine through. Our job is to perform admirably in the sidelines.


Some of Our Mechanical Engineering Work

Heating, Ventilation and Air Conditioning (HVAC): We create healthy indoor environments that are energy efficient and cost effective.

Commercial buildings need to be heated and cooled for the comfort and productivity of the occupants. Buildings need to be ventilated because humans breathe in oxygen and exhale carbon dioxide. When not enough oxygenated outside air is introduced into the building carbon dioxide levels increase and make people sleepy and unhealthy. Other “pollutants” must also be regularly flushed from the building in order to have good indoor air quality.

Buildings must offer a healthy indoor environment. This is achieved by meeting code requirements. It is also achieved by designing for correct quantities of outside air to be brought into the occupied buildings.

There are many system types with costs and comfort impacts that can all meet the HVAC needs of a building. G&M helps by engineering the right system to meet the architect/owner’s requirements.


Plumbing & Refrigeration: From grocery stores to government buildings, apartment complexes, and massive warehouses, our plumbing and refrigeration engineering services will create simple, elegant solutions for your project.

Plumbing and refrigeration get talked about together because they are piping systems. Plumbing systems provide health and safety for building occupants. Clean water, properly disposed of waste, and venting of waste piping are all critical to the health and safety of occupants. G&M mechanical engineers design both the HVAC and plumbing systems for buildings.

Refrigeration is a mechanical refrigerant based heat transferring process. On a simple basis a refrigerator removes heat from inside the box and transfers it to outside of the box. The same is true of buildings. We remove heat from inside the building and transfer it to the outside. For example, complex refrigeration systems are used in grocery stores. G&M staff are trained to design those systems. Ground coupled heat pump or variable refrigerant flow systems are engineered for commercial buildings where high levels of energy efficiency are requested.


Laboratory & Medical Systems: Schools, businesses, and hospitals all need special ventilation systems. We design them for maximum efficiency.

Laboratory ventilation systems for schools, businesses, and hospitals are engineered by G&M. Properly designed ventilation systems provide safety by keeping dangerous fumes or pathogens away from staff when they open the sash on a fume hood. Sensitive air pressure controls maintain the correct positive room pressure to the negative hood pressure. Medical ventilation systems provide healthy environments for surgeries and for patients with contagious diseases or impaired immune systems. Ventilation air for surgery suites has to be tempered, humidified, and HEPA filtered providing a positive room air pressure. Staggered air pressures provide infection control between patient rooms.


HVAC System Controls: Gausman & Moore specifies building automation systems that include sequences of control for the HVAC system. And we make sure they work as they are supposed to.

For example, the control sequences tell the equipment:

  • How to operate during occupied and unoccupied hours

  • What the summer and winter interior temperatures should be

  • How much outside air should be brought in based on the building occupancy

Our commissioning authority provides functional testing to verify that as the building automation control is run through the various sequences of control, the equipment, sensors and actuators are all operating as they were designed to.


Fire Protection, Smoke Control: G&M has two registered fire protection engineers on staff. They design sprinkler systems to put out fires in buildings, as well as cutting-edge smoke control systems.

The fire protection systems may be wet, dry, chemical or pre-action type systems depending on the building use. Smoke control systems use fans to control building air pressures to keep smoke out of stairwells so that staff can safely escape a burning building.


Ground Source Heat Pumps: We have designed these efficient heating and cooling systems for schools, a historic courthouse restoration, military buildings, and more.

Ground source heat pumps provide heating and cooling for residential and commercial buildings by transferring heat to and from the ground that maintains an average temperature (below the frost line) of approximately 50 DF.

Wells are drilled typically 200 – 300 feet deep, plastic pipe is looped down the hole and connected to a header so that propylene glycol can be circulated through the system. The building’s cooling load typically determines the number of wells that are needed. This is an electrically driven system, but the efficiencies of transferring heat instead of creating heat are what make it attractive. This a very high construction cost system.

As building energy performance requirements increase we will see more of these systems.


Variable Refrigerant Flow (VRF): Like ground coupled heat pumps, VRF systems are highly efficient because they primarily transfer heat.

A significant additional efficiency comes from the flow of refrigerant to transfer heat instead of using air or water. This is a relatively new system in the US, but has been used for a decade in the Far East. This system is especially well suited to retrofitting older buildings where routing of large pipes or ducts is difficult and expensive. G&M has engineered two of these systems.


Solar Hot Water: We have engineered multiple solar water systems that increase efficiencies in buildings with high hot water usage.

Solar Domestic Hot Water systems are being driven by third party rating system requirements (LEED and B3 SB 2030) and by efficiencies when there is a high domestic hot water use in the building (Ex. lots of laundry, dishwashing, or showers). G&M has engineered these systems for many years including a large system for the Ft. Carson Brigade Battalion Headquarters (BBHQ).
