BHB provided the HVAC, plumbing, lighting controls, and power design for renovations and additions at Austin Ridge Bible Church’s Bee Cave campus in Austin, Texas. The congregation was growing in size, and more space was needed to accommodate members and guests. The project consisted of three phases: the addition of a new 79,818 square-foot worship center with 1,500 seats, a new 140,713 square-foot parking garage in close proximity to the worship center, and renovations to an existing building on campus.

For the two-story worship center, an overarching challenge that affected mechanical, plumbing, and electrical designs, was that while the new facility was 90% open structure, no piping, HVAC units, or electrical conduits could be exposed in the concourse. This left the BHB team a very small window of space to work with in order to hide all of the necessary equipment. Mechanical engineering services included the design of a Variable Refrigerant Flow (VRF) HVAC system. While most VRF systems have rooftop units, the building Owner wanted the large air handler units indoors, which provided a challenge in trying to hide the system in open ceilings. Other mechanical design services consisted of providing 100% exhaust for the worship center and meeting acoustic requirements so that each sermon can be broadcasted to a virtual audience. BHB’s plumbing design incorporated the architect’s desire to have subsoil drainage under the entire footprint of the building, without exposing any piping.

BHB’s electrical engineers designed the electrical infrastructure for the parking garage and worship center, as well as the lighting controls to meet the 2015 International Energy Conservation Code (IECC). Since the church campus is located on a large and steep hill, it was challenging to find routing for cables in order to provide new electric service from an existing manhole. The design was successfully completed, and construction is now underway. Estimated to be complete towards the end of 2019, the new worship building, parking garage, and overall renovations will allow the church to hold more people and further extend its reach to the community.
