Written by GovTribe AI ·

This is a Mechanical Equipment Schedules document for the Ridgeland High School Renovations project, prepared by Southern A&E, LLC for Walker County Schools in Georgia. The document provides detailed specifications for HVAC and mechanical equipment required for the renovation project, issued for construction as part of Bid Package BP-1. The schedules include 16 duct furnaces (Modine models ranging from DFS150 to DFS400), multiple air distribution components including transfer grilles, exhaust/return grilles, and supply diffusers, five electric heaters (Markel models), 11 mini-split indoor units (Carrier models), 11 mini-split outdoor units (Carrier models), three rooftop heat pumps (Carrier models), one dedicated outside air unit with energy recovery (Greenheck model), two make-air units (Carrier models), two pipe chase housings (Alta Products models), and two electric unit heaters (Markel models). All duct furnaces operate on natural gas with 81% AFUE efficiency and are sized between 150,000 and 400,000 BTU/hr input capacity. Mini-split systems include cooling capacities ranging from 12,000 to 36,000 BTU/hr and heating capacities from 12,000 to 37,000 BTU/hr, with efficiency ratings of SEER2 24-25.2 and HSPF2 9.5-9.8.

The document specifies that all equipment performance data is based on manufacturer's nominal values and references additional specification sections (235513, 238216.14, 238126, 236200, 237433, 237423, 237200, and 238239.16) for complete features and installation requirements. Key installation requirements include factory-insulated diffusers, wired 7-day programmable thermostats on all mini-split units, air treatment systems meeting ASHRAE 62.1 standards for units exceeding certain capacities, rotary-style condensate lift pumps, low ambient kits for cooling to 0°F on mini-split outdoor units, hot gas reheat on dedicated outside air units, and field verification of wall-mounted replacement grille dimensions prior to ordering. All electrical characteristics and control specifications are referenced in separate electrical drawings and control specification sheets. The document revision date of November 21, 2025 (AD2) reflects the second addendum issued for the project.
