OpenTable, the national online restaurant-reservation service company, was looking to adaptively reuse a 36,000-square-foot warehouse building as their new support center in Centennial, Colorado. Unlike a typical office build-out, they were looking for a fun-themed space equipped with collaboration areas, a training facility, a library, an indoor patio, coffee bars, a dining room, and a bar.
360 Engineering worked under Venture Architecture to provide mechanical and plumbing engineering consulting and design services to support this innovative, modern office space. Our work began by assessing the existing mechanical equipment and providing a thermal zoning sketch outlining the number of anticipated zones for thermal control and reviewing this with the client. During design, new rooftop units were added based on load calculations to meet the new capacity needs of the space. Plumbing design included new restroom groups, fitness room shower facilities, breakroom sinks, and janitor mop sinks. Also, new gas piping for the rooftop units from the existing meter and performance specifications for the fire protection system was included in the design. Finally, our engineers provided site observations and a final punch report during the construction phase.
A members-only luxury vacation club, Exclusive Resorts, selected McGregor Square as their Denver corporate headquarters location. Next door to Coors Field, in the heart of Lower Downtown Denver (LoDo), McGregor Square offers modern office suites connected to retail shops, restaurants, and an expansive outdoor plaza.
On the Venture Architecture team, 360 Engineering provided mechanical and plumbing engineering design for the tenant interior buildout of the 16,000-square-foot office space for Exclusive Resorts. The space includes an open office area, individual offices, conference rooms, board room, wellness room, break room, reception, IT, copy, and storage.
The new space layout’s mechanical design added energy-compliant VAV boxes and thermostats compatible with the base building control system, air distribution, and terminal devices. In coordination with the architectural team, our mechanical engineers worked to hide all mechanical equipment in the drop ceiling, maintaining the space’s visual appeal. The sound was another consideration, designing the HVAC system to be as quiet as possible. Lastly, ensuring the proper amount of outside air was entering the space while working within the base building system parameters.
Growth between Castle Rock and Colorado Springs prompted UPS to expand and construct a new distribution center in Monument, Colorado. The nearly 100,000-square-foot facility was built on 16.9 acres just off Interstate 25, helping meet growing demand in the area.
Experienced industrial architect, Ware Malcomb, led the team of architects and engineers in designing the building containing 4,300 square feet of office space with a customer counter, 2-bay auto shop, heated/ventilated warehouse, plus a separate guard shack entry point. 360 Engineering designed the mechanical systems per UPS’s design guidelines and specifications, offering unique solutions when needed. The HVAC systems include constant volume RTUs, gas unit heaters, direct-fired heating and ventilation units, and a VRF for the guard shack. The plumbing systems include restrooms, janitor’s closets, trench drains, sand and oil interceptor, roof drains, and a compressed air system.
According to UPS.com, UPS employs more than 500,000 people in 220 countries and generated $97.3 billion in revenue last year. The company delivers 25.2 million packages daily; it has a fleet of more than 100,000 delivery and other vehicles and more than 500 owned and leased aircraft.
Looking to enhance their member experience, the Denver Athletic Club transformed 6,700 square feet into a new modernized coworking space and lounge. Through a design-build contract, 360 Engineering provided mechanical and plumbing engineering services for this coworking space, plus the renovation of restrooms on the 2nd and 3rd floors.
Our work began with assessing the existing mechanical, plumbing, and gas piping systems, followed by a Preliminary Design Pricing Narrative outlining three mechanical system options. Once we had the design direction, 360 Engineering produced REVIT drawings through Construction Documents and proceeded with Construction Administration services with a final punch walk upon completion.
Once the tallest building in Denver, the DAC was constructed in 1890 with several additions throughout the decades. Our team overcame significant challenges due to the building’s age with existing structure and space constraints above hard lid ceilings and managing old abandoned existing mechanical and electrical conduit piping and ductwork from years past.
Located off the 16th Street Mall in Downtown Denver, 16 Market Square is a 260,000-square-foot, nine-story mixed-use building, with top floors consisting of residential units. For long time client, Lincoln Properties, 360 Engineering has provided consulting and mechanical design for upgrades at the building, most recently upgrading the cooling tower.
The building had two (2) 400-ton cooling towers serving the condenser water loop for the building that needed replacement. The existing units were reaching the end of their useful life, and the forced draft style towers were also chronically difficult to maintain. The existing condenser water loop temperature was noted to rise during peak cooling days, so the current cooling load for the building was evaluated and documented in the summary and options for the cooling tower replacement. Based on 360 Engineering’s recommendations, the client selected a single (1,000-ton) cooling tower for the replacement. This project was challenging based on the existing structural base (built for two smaller units), the current windscreen structure, the cooling tower’s location on the roof, and the location of the building.
360 Engineering worked closely with the client and structural engineer to coordinate a design to provide proper cooling capacity for the building occupants, safely secured and protected on the roof, with minimal noise disturbance to the top-floor residential units. 360 also brought in and coordinated with an architect to produce full building elevations required to apply and obtain a zoning approval permit from the City and County of Denver.
During construction, 360 worked closely with the General Contractor to obtain building permits, coordinate submittal and RFI reviews with subcontractors and engineering sub-consultants, and update specific design elements based on field conditions and alternate strategies discussed with both contractors and engineering consultants. Additionally, 360 provided commissioning services to optimize the operation of the new cooling tower and associated systems and controls.
Founded in 2002, Crocs operated out of their Niwot, Colorado headquarters until 2020. At that time, this worldwide distributor of casual footwear moved their home office to Broomfield, Colorado, where they occupy a single-story building, over 88,000-square-feet in size. Working with Venture Architecture and the design team, 360 Engineering’s mechanical engineers helped shape this new core-and-shell space into a functional and fun work environment for Crocs employees.
The architect’s vision called for a very open feel with limited enclosed rooms and even less ceiling. With a roof deck height of almost 25 feet, this presented an opportunity to showcase mechanical and plumbing infrastructure as part of the aesthetic, but also the challenge of providing uniform comfort in such a vast space. The team paid particular attention to detail with the exposed ductwork layout by establishing three horizontal planes, resulting in a visually appealing design. Then selecting visually unobtrusive routing to the enclosed rooms and selecting the appropriate diffusers to optimize airflow and noise. Additionally, pear-type destratification fans ensure proper air movement and increased energy efficiency.
On the plumbing side, the buildout included multiple living wall features needing special care during design and construction administration for water supply and drainage requirements. 360 Engineering also provided cost-saving measures by collaborating with the plumbing contractor early in design to strategically add an extra length of pipe to the existing main sanitary waste line. The existing waste line exited the building deep below the slab, so the additional length reduces the number of deep connections to the main.
Owner and operator of numerous year-round outdoor destinations, Alterra Mountain Company, moved into their Denver, Colorado headquarters in 2018. Their 35,000-square-foot office space located in Denver’s RiNo neighborhood, encompasses the entire 4th floor and a portion of the 3rd floor of the Zeppelin Station building.
The Venture Architecture design team took the wide-open core/shell space and transformed it to fit Alterra’s needs. While preserving the majority of the space for open offices, the team added conference rooms, private offices, IT spaces, and an extensive breakroom area, complete with a walkout rooftop patio. 360 Engineering provided mechanical and plumbing engineering services from design through construction including coordination with architectural elements and electrical/lighting layout.
The HVAC design modified and expanded the existing Variable Refrigerant Flow (VRF) fan coil system with a Dedicated Outside Air System (DOAS) for heating, cooling, and ventilation of the occupied spaces as well as 24/7 cooling for the IDF room. The plumbing design added significant infrastructure for the breakroom space, modified the core restrooms, and added a unisex restroom and three showers.
360’s design accommodated the new accent fireplace in the reception area and provided unique thermal zoning and controls considerations for several garage doors throughout the space to ensure occupant comfort and energy efficiency whether they are open or closed.
Since 2007, 360 Engineering has provided mechanical engineering consulting and design services for FirstBank facilities across Colorado. FirstBank was looking to expand its training space in Lakewood, Colorado. 360 Engineering worked with FirstBank and the architectural design team to remodel existing space previously used for offices and conference rooms. The firm met the challenge of providing a modern, high-tech, training environment in a building with older equipment nearing maximum capacity.
For this updated space, the mechanical design included redistribution of supply air ductwork and diffusers, modifications to the temperature control system, and coordination with the architect and electrical engineer for diffuser layouts with lighting and ceiling features. The plumbing design involved the relocation of the third-floor restrooms, the addition of a restroom on the second floor, and modifications for the breakroom on the second floor.
As a mechanical and plumbing engineering firm on Jacobs Denver International Airport (DEN) on-call A/E design team, 360 Engineering has completed several projects at DEN. For the expansion of the Southwest Airlines maintenance storage area in Concourse C, the firm provided mechanical and plumbing engineering for the buildout of 16,400 square feet of space. This space included offices, conference room, break room, locker/shower rooms, a toolbox storage area, an oxygen room (with dedicated exhaust system), and a 6,000 square foot material storage/staging area.
360 Engineering’s involvement began with initial site planning and coordination to observe existing mechanical, plumbing, and fire projection systems. During the design phase, existing mechanical and plumbing systems were modified to support the remodeled areas. The design challenge during this project was trying to provide full capabilities for the space while dealing with the limitations of the existing systems at DEN. Existing hydronics were approaching capacity, and the team was tasked with providing outside air for Southwest’s parts/storage area where forklifts operated.
For fire protection, performance specifications were provided for the design/build fire protection contractor to use. Finally, construction administration services were provided, including the review of submittals, answering any RFI’s, OAC meetings, and final punch walk with a report.
