This document is a technical specification schedule for mechanical systems equipment and services. It contains three integrated schedules detailing pump systems, hot water boiler systems, and a chilled water buffer tank for what appears to be a federal facility infrastructure project.

The pump schedule specifies five units across various applications: a primary hot water boiler circulation pump (BP-110 S), secondary hot water pump (P-1.2), primary chilled water pump (P-3.4.5), secondary chilled water pump (P-6.7), and a condenser heat recovery pump (P-8.9). These units are located at MECH 1403 and CHILLER YARD locations and feature water-based fluid systems with operating temperatures ranging from 42°F to 347°F. Specifications include impeller diameters ranging from 6.2 to 8.0 inches, GPM outputs from 30 to 70, and minimum efficiencies between 71% and 86.4%. Key requirements mandate premium efficiency motors with variable speed drives, parallel pump configuration with shared redundant capacity, full-size impellers balanced to design conditions using VFD, and TEFC motors rated for outdoor conditions. The hot water boiler schedule details six firetube/condensing boiler units (B-1 through B-6) with maximum outputs of 379 IMBH, minimum gas inputs of 80 IMBH, and operating pressures of 4.0 IN WG. These units require multiple boiler controller integration with BACnet compatibility, direct spark ignition with modulating gas valve and 5:1 turndown capability, thermal efficiency of 95% or higher, and ASME CSD-1 compliance. The chilled water buffer tank (CWBT-1) is a vertical unit with 680-gallon capacity, 2-inch flange connections, and requires R-20 insulation with factory-installed heat tape and jacketing for outdoor installation.
