After being contacted by the general contractor, we met on site to go over the possibility of installing a snowmelt system for the more than 2,000-square-feet of sidewalks, which also included two ADA-sloped approaches to the grand entrance, a wide sweeping brick stairway and the landing pads outside the grand entrance. Natural gas was available, and a new mechanical room could be created out of an unused portion of a storage room area on the first floor. The design load was a net 340,000-Btu/h.
Placement of manifold vaults were detailed, and a second redundant modulating condensing boiler was incorporated. The cost was higher than anticipated, so the project was divided up into two phases: the 816-square-foot main corporate grand entrance, sweeping stairway, ADA sidewalk ramps and front sidewalk adjoining both ADA ramps as phase-one (see drawing); and the 1,200-square-foot sidewalks leading to employee parking lots would be phase-two.
