4-Ton Bard HVAC Units - Brand Name Only

Statement of Work (SOW) Project: Replacement of Seven (7) 4-Ton Bard HVAC Units 1. Executive Summary This Statement of Work (SOW) defines the requirements, deliverables, and scope of work for decommissioning, removing, and replacing seven (7) existing 4-ton Bard wall-mounted HVAC units. The existing units will be replaced with new, energy- efficient Bard units utilizing modern, environmentally compliant refrigerant in strict accordance with EPA regulations, local building codes, and industry best practices. 2. Project Objectives • Decommission and Remove: Safely recover refrigerant and decommission seven outdated 4-ton Bard units. • Install New Units: Supply and install seven brand-new, high-efficiency 4-ton Bard wall-mounted units featuring up-to-date, non-ozone-depleting refrigerant. • These seven units directly support high-sensitivity, mission-critical operational spaces—specifically Electrical Panel & Switchgear Rooms and Chiller Plant & Control Locations—the primary engineering objective is to maintain strict, non- stop climate thresholds to prevent thermal equipment failures, safety tripping, or localized moisture issues. • Compliance & Safety: Ensure all work meets local mechanical, electrical, and environmental safety regulations (specifically EPA Section 608). • System Integration: Connect new units to existing electrical systems, ductwork, and environmental controls, ensuring fully operational climate control in the designated facility spaces. 3. Detailed Scope of Work The Contractor shall provide all labor, materials, equipment, tools, transportation, and supervision necessary to complete the following tasks: -- 1 of 7 -- Phase 1: Pre-Installation & Site Preparation • Conduct a comprehensive site survey to verify electrical compatibility, structural wall integrity, mounting brackets, and ductwork dimensions. • Coordinate with facility management to establish a safety perimeter, staging area, and work schedule to minimize operational downtime. • Secure all necessary approvals required by local base jurisdictions before commencing physical work. Phase 2: Decommissioning & Removal of Existing Units • EPA Section 608 Compliance: Safely and legally recover all existing refrigerant from the legacy units using certified recovery equipment in strict accordance with EPA Section 608 regulations. No venting of refrigerant is permitted under any circumstances.Recovery Cylinders: CE will provide the necessary recovery cylinders to the contactor to recover any refrigerant remaining in the existing Bard Units. The Contractor must submit a highly detailed, certified Refrigerant Recovery Log & Manifest directly to CE (Civil Engineering / Client Entity) prior to physical equipment disassembly. A separate recovery log must be completed for each of the seven (7) individual units (indexed by unit physical location and manufacturer serial number • Electrical Disconnection: Safely disconnect electrical power and control wiring, following standard lock-out/tag-out (LOTO) safety protocols. • Mechanical Removal: Detach the seven (7) 4-ton Bard units from their wall mounts and duct connections. • Disposal & Recycling: Transport and legally dispose of the old units, including the recovered refrigerant, at a licensed disposal/recycling facility. Provide disposal manifests and certificates to the client. Phase 3: Equipment Procurement & Specifications The Contractor shall procure seven (7) brand-new Bard wall-mounted units meeting or exceeding the following minimum technical requirements: • Capacity: 4 Tons (nominal 48,000 BTU/h cooling capacity per unit). Contract is still responsible and confirms the current tonnage of the current units. • Legacy Equipment Inventory (Existing Units to Be Replaced) • The Contractor is responsible for removing, cataloging, and replacing the following specific legacy models currently installed at the facility: -- 2 of 7 -- Unit Number Equipment Location / Serviced Space Mfg Legacy Model Number Unit 1 Electrical Panel Room / Switchgear Bard WA602-C15V Unit 2 Electrical Panel Room / Switchgear Bard WA602-C15V Unit 3 Chiller Plant Room Bard W48A2-C09XPXXXJ Unit 4 Chiller Plant Room Bard W48A2-C09XPXXXJ Unit 5 Chiller Control Room Bard PA13482-C Unit 6 Critical Support Area Bard WA372-C15B Unit 7 Auxiliary Infrastructure Room Bard WA701-C15B • Type: Wall-mounted Air Conditioner and Heat Pump (matching current configuration). • Refrigerant: Eco-friendly, up-to-date refrigerant compliant with current EPA regulations (R-454B / R-32 depending on current model availability and safety standards). • Electrical: Must match existing facility power supply (typically 208/230V or 460V/60/3 phaseto be verified during site survey). • Controls: Compatible with existing thermostats/building automation systems, or include new digital programmable thermostats. • Filtration: MERV 8 minimum, or as specified by facility standards. Phase 4: Installation of New Units • Sleeve & Framing Inspection: Inspect, clean, and structurally reinforce the existing wall framing, sleeve, and duct interfaces. Prepare wall openings, inspect flashing, and install new heavy-duty mounting brackets or wall sleeves as required. • Mandatory Minimum Clearances: The Contractor must ensure the physical placement of each installed unit conforms to the manufacturer's engineering specifications to prevent hot air recirculation and facilitate maintenance. Mount the seven (7) new 4-ton Bard units securely to the exterior walls. • Weatherproofing & Air Barrier Standards: • Gasketing: Apply commercial-grade, heavy-duty, closed-cell, UV-resistant neoprene weather-sealing gaskets around the entire perimeter of the wall sleeve interface. Gaskets must be compressed uniformly to form a continuous air and water barrier. • Sealant Quality (ASTM C920): Seal all exterior seams, mounting flange edges, and fastener penetrations with a high-performance, non-sag polyurethane or -- 3 of 7 -- hy…
