Atherton Town Center

The Atherton Town Center project is comprised of a new city hall, library, police ancillary and remodel of the old existing town hall. Harris provided complete mechanical and plumbing systems, including controls and balancing on all structures. The main buildings are tied together through a 17K+ lb. mechanical heat pump system with a 118-ton heating/cooling capacity and interlocking BAS controls.

The new City Hall building includes 3 air handing units, 4 mechanical pumps, VRF condensing units, fan coils, multiple exhaust fans and integrated in-slab radiant tubing as well as an Italy sourced multilevel radiant grid system comprised of over 1100 ceiling panels, 11 manifolds and in-wall sensors to reduce the structures carbon footprint. The new library building includes a single rooftop AHU with multiple exhaust fans that circulate air through a Durkeesox fabric duct system installed below a floating floor along with 12 fan powered terminal units.

One challenge of this project was the radiant ceiling panel system. Each panel required 2’ tubing whip connections that tied into a backbone that each served 10-50 panels, depending on the room application. Due to the ongoing pandemic, material delivery was substantially delayed and compressed the schedule, leaving minimal room for error during our installation phase. Layout, staging and productivity were key when working with so many moving parts. Once the field crew adapted to manufacturing line principles, productivity substantially increased and the schedule constraints could be achieved.
