Berthoud Recreation Center

The Town of Berthoud opened its new Waggener Farm Park recreation center and indoor aquatics facility in November 2021. The recreation center includes a gymnasium, cardio and weight training area, group fitness room, child-watch area, party room, administrative space, climbing wall, locker room, family changing space, and mechanical and storage areas. 360 Engineering provided mechanical and plumbing engineering design services for the new ground-up 34,275 square foot facility.

Given the diversity of uses throughout the building, the mechanical system is equally diverse. Single-zone VAV rooftop units serve the large gym and fitness areas. A specialized pool unit serves the natatorium with energy recovery and dehumidification. Also associated with the pool is chemical storage, which has corrosion-resistant fans. An energy recovery unit serves the locker room area with high air changes. Fan-powered and shut-off VAV boxes fed by rooftop units serve the other spaces. With the variety of uses and ceiling finishes comes various ductwork, from aluminum in the pool areas to handle high humidity to PVC for corrosive fumes, lined ductwork for acoustics, and exposed spiral for aesthetics.

360 Engineering coordinated closely with the pool designer to incorporate a new deck-level exhaust system technology to capture evaporating chemicals on the pool surface before they can mix in the air, improving natatorium air quality. There are also high-volume, low-speed fans in the large open areas for destratification, including the pool, to reduce energy use and increase comfort.

Lone Cone Public Library

The community of Norwood, Colorado, welcomed a brand-new public library and gathering place. In addition to general library space, the nearly 11,000-square-foot building features a lobby, children’s area, multipurpose room, business center with conference room, study rooms, offices, break room, warming kitchen for events, and restrooms. The 2,000-square-foot multipurpose room and warming kitchen provide flexibility for the community to hold meetings and catered events.

On the Anderson Hallas Architects team, 360 Engineering provided mechanical and plumbing engineering consulting and design services. As a primarily tax-dollar funded project, in addition to occupant comfort, the budget was an important factor when selecting the mechanical system. The prefabricated metal building did not allow for roof-mounted systems, so the mechanical design included a grade-mounted RTU and several gas furnaces with split DX cooling. These small furnaces worked well with the architectural design as they fit in tighter spaces, allowing for maximum use of space.

In addition to mechanical and plumbing design, 360 Engineering performed an energy model analysis, helping meet the project’s Green Globes rating system goals.

Denver Northfield Fire Station No. 39

To meet the needs of the growing Northfield neighborhood in northeast Denver, the Denver Fire Department proposed the construction of a new 2-bay fire station to improve their response time for medical and fire emergencies and maintain services associated with the forecasted population growth. The OZ Architecture A/E team designed the new fire station, 360 Engineering fulfilled the mechanical and plumbing engineering services.

The new fire station has apparatus bays, living quarters, a watch office, a fitness area, a community room, a hose tower, a communications tower, and additional spaces to support the needs of the Denver Fire Department. The capacity requirements included housing one fire company — nine firefighters, three engineers, two lieutenants, and one captain — with the capacity to house two companies in the future.

With a LEED Gold goal, the mechanical system design involved a high-efficiency packaged rooftop unit with VAVs, providing heating, cooling, and ventilation to the fire station. Exhaust systems were specified for the kitchen, restrooms, locker rooms, and fire station bays. Make-up air was designed for building pressurization associated with the fire station bays.

The plumbing system design included interior spaces and exterior hose bibbs. In addition, the plumbing design included drains in the fire station bays, sand & oil interceptor for drains in the fire station bays, and coordination with the Civil Engineer on the location of the waste line connection to the main.

Denver Fire Station No. 39 was completed on schedule and celebrated its grand opening on May 31, 2019. The facility is now USGBC LEED Gold Certified.

Longmont St. Vrain Memorial Recreation Center

Located in Longmont’s historic old town district, Longmont St. Vrain Memorial Recreation Center has an indoor gymnasium, locker rooms, classrooms, group fitness room, and weight room with free weights and other exercise equipment.

Hired by Rocky Mountain Trane, 360 Engineering completed a detailed field assessment and provided the Recreation Center with a solution to the indoor gymnasium’s failing Air Handling Unit (AHU). The unit had been modified since installation to serve adjacent yoga and kids tumbling rooms, so the Recreation Center was also looking to improve the zoning in these rooms. Special heat requirements were met for the yoga room to accommodate hot yoga classes.

The final design replaced the failing AHU with (2) Variable Air Volume (VAV) AHU’s with re-heat terminal boxes to separate the gymnasium from other zones at the recreation center and to optimize thermal comfort.

Denver Mountain Parks – CCC Camp Morrison

One of Denver Mountain Park’s 46 properties, the Civilian Conservation Corps (CCC) Camp in Morrison opened in 1935. At one point about 200 men lived in these barracks just south of Red Rocks Park completing various conservation projects.

HistoriCorps, a nonprofit focused on providing volunteers to preserve historic structures around the country, set out to restore 11 of the 14 buildings at the CCC camp in Morrison. One of the old barracks eventually becoming their new office space. Anderson Hallas Architects provided the design to restore this historic barrack and help transform the space for HistoriCorps staff members.

Under Anderson Hallas’ design team, 360 Engineering provided mechanical engineering services from initial site assessment through construction administration. The firm worked within a tight construction budget and followed the client’s direction to use evaporative cooling, which significantly increased duct sizing. These constraints created an added challenge related to duct routing in this historic structure. In the end, the new HVAC and plumbing systems helped convert the space to a comfortable, functional, office environment. HistoriCorps was able to move-in and continue their rehabilitation work at the CCC camp and throughout Denver Mountain Parks.

1881 Pierce – HVAC Replacement Commissioning

The State of Colorado and 360 Engineering have a strong partnership, built throughout multiple mechanical engineering projects completed for the Colorado Capitol Complex buildings and other State buildings. The State hired 360 Engineering to provide HVAC Commissioning Services for Phase 2 and 3 of an HVAC Replacement at 1881 Pierce Street, in Lakewood, Colorado. The Phase 2 project scope involved replacement of two air handling units (22,200 & 24,475 CFM) with hot water and chilled water coils and the two associated return fans. The Phase 3 project scope included replacement of approximately 50 VAV boxes.

360 Engineering developed the detailed commissioning plan establishing individuals’ roles and responsibilities in the commissioning process, requisite documentation, meeting schedule, equipment readiness prerequisites, equipment start-up requirements, functional performance test procedures, acceptance criteria, and O&M training obligations. 360 Engineering reviewed design documents, equipment submittals, system verification checklists, test and balance procedures, and functional performance test results.

During commissioning, 360 Engineering discovered the like for like replacement of the air handling unit did not achieve the fan performance specified and further examination revealed an existing section of ductwork was short circuiting the return fan and needed to be corrected by the design engineer to achieve proper operation.

City of Lakewood – Carmody Park

South Adams County – Water & Sanitation District Administration Building

The new 13,000 square-foot South Adams County Water and Sanitation District Administration building was constructed on the site of the District’s existing facility. Construction was phased to allow administrative functions to remain operational until the transition to the new space. The new building, twice the size of the original, was designed to operate at a similar utility expense.

Mechanical design for the project consisted of utilizing a large concrete reservoir system as the heat sink for a heat pump system. The reservoir water is pumped into the building, through a heat exchanger, and then returned to the reservoir with an overall temperature rise of less than 2° F on design day conditions. A separate closed-loop system of condenser water is located within the building and is pumped through the heat exchanger and out to the heat pumps located throughout the building.

The overall building was also reviewed and studied with the architect to site the building with reduced window exposure in the summer, utilizing overhangs to shade the south and west windows, keeping a careful eye on the window to wall ratios, and evaluating the insulation used in the walls and roof for a highly energy-efficient building.
