Replacing the City of Grapevine’s original animal shelter, Baird, Hampton & Brown provided the MEP engineering design for this new, 13,245 SF animal services facility.
The building is equipped with indoor cat condos and play yards for dogs and a get-to-know courtyard allowing the public to enjoy personal time with their potential pet. The facility also includes a heated and ventilated drive-thru sally port for secure delivery and transfer of animals. Interior spaces include offices and rooms for laundry, medical, recovery, grooming, and isolation/quarantine uses.
The electrical design includes an 800 amp, 120/208 volt 3-phase distribution system to support the building’s power needs and is equipped with complete security, surveillance, and access control systems. All lighting in the building is controlled by a combination of time-controlled relays, motion sensors, and daylight harvesting sensors that dim and brighten the lights in special areas based on the amount of ambient light.
Using roof collectors that funnel sunlight through reflective ducts, a solatube system was installed throughout the building to provide natural light into all animal spaces.
The mechanical system utilizes a 100% outside air unit that closely controls temperature and humidity. The unit exhausts 100% of the air from each space through an energy recovery wheel which tempers the incoming air to save energy. In addition, all animal spaces are designed to minimize odors and confine airborne particles to promote a healthy environment.
The plumbing design incorporates low-flow plumbing fixtures for water conservation and equips each dog kennel with trench drains and wash-down systems to maintain cleanliness.
A wet pipe fire protection system and fully recessed sprinkler heads were also specified in all areas with ceilings to provide a neat, clean appearance throughout the City’s new shelter.
