SECTION I – GENERAL REQUIREMENTS & SUMMARY OF WORK

1.1 General Scope of Work & Project Boundaries

A. The work under this contract includes providing all labor, equipment, tools, materials, and supplies required for the complete, turn-key replacement of the HVAC system at the Range Operations Building in Glen Arm, Maryland.

B. All activities shall comply explicitly with this technical document and all Division 0 parameters managed via eMMA.

1.2 System Requirements (Electrification & Low-GWP Transition)

A. The existing system to be fully extracted comprises a 2.0-ton single-stage split system AC (Gibson Model WSA2BE4M1SN24K running R-410A) .

B. The contractor shall supply and install a modern, all-electric split-system heat pump with a matching 17.5-inch wide indoor multi-position electric air handler unit.

C. Refrigerant Compliance: In line with state carbon reduction goals and current EPA safety mandates, the replacement hardware must utilize certified low-GWP refrigerants (such as R-32 or R-454B). Legacy R-410A equipment will not be accepted.

D. Electrical Upgrade: The contractor shall inspect the field distribution panel and install a dedicated 240V single-phase circuit to safely feed the new electric air handler and its integrated backup electric resistance heat strips.

1.3 Demolition, Extraction & Legal Disposal

A. Perform safe, compliant reclamation of all legacy R-410A refrigerant from the old Gibson system per EPA Section 608 protocols. Provide recovery logs directly to the Project Manager.

B. Completely dismantle, decommission, and extract the old condenser, indoor cased coil, and gas furnace assembly.

C. Safely cap, seal, and isolate all decommissioned fossil fuel gas line inputs and combustion flue paths according to state mechanical code.

D. Provide complete off-site removal and legal, certified disposal of all debris, scrap framing, and abandoned hardware.

1.4 Rigging, Structural & Utility Protection

A. The contractor shall supply all specialized rigging, cranes, hoists, safety barriers, and transport carts to move heavy hardware on and off the site without compromising structural elements.

B. Any damage to floors, structural walls, entry pathways, and surrounding utilities occurring during the execution of this contract must be repaired immediately by the contractor to pristine, original structural condition at zero additional cost to the State.

1.5 Site Conditions, Rubbish & Housekeeping

A. Standard Operational Hours: Work shall take place Monday through Friday, between 6:30 AM and 5:00 PM. Alternate schedules require formal, written clearance from the facility manager.

B. The workspace must be actively kept free of dust, debris, and dangerous accumulations of construction trash.

C. Shift Cleanup: At the close of each daily work shift, the contractor must sweep the zone, secure all tools, and transition active rubbish out of the workspace or into a single pre-approved, localized container area. No utility hookup or mechanical room asset may be left in an unsafe or uninsulated condition overnight.

SECTION II – TECHNICAL SPECIFICATIONS & SUBMITTALS

2.1 Materials and Equipment Performance Standards

A. All hardware provided under this contract must be commercial-grade, factory-new, and carry certified AHRI performance metrics matching or exceeding a nominal 2.0-ton (24,000 BTU) heating and cooling profile.

B. The system must meet or exceed 14.3 SEER2 and 7.5 HSPF2 efficiency ratings.

C. The indoor air handler must feature a constant-torque ECM or variable-speed blower fan configured to match nominal target airflow values. The indoor cabinet physical profile must not exceed 17.5 inches in width to match the existing cabinet footprint without requiring complex sheet metal duct field conversions.

2.2 Thermal Protection, Heat Breaks & Winterization

A. To prevent past system stress caused by extreme winter operations, the contractor must optimize structural heat retention and safeguard core mechanical components.

B. All newly exposed structural connections and duct adapters must include specialized physical heat breaks engineered to minimize thermal bridging.

C. Provide high-grade, commercial insulation wraps, internal linings, or thermal insulation sheets across the air distribution lines and internal plenum connections to safeguard ignition-related assemblies from freeze weather exposure and maximize performance efficiency.

2.3 Material Submittals & Engineering Data

A. Prior to procurement, the contractor must compile and submit a rigorous digital submittal package to the DGS Project Manager for approval.

B. The submittal file must include manufacturer cut sheets, physical sizing specifications, electrical load requirements, line-set design choices, AHRI certificates, and data sheets regarding the thermal properties of the proposed insulation and heat break components.

2.4 Contractor Qualifications & Professional Licensing

A. The executing firm must hold an active commercial Maryland HVAC contractor license and have a verifiable track record of technical competence delivering similar split-system or heat pump replacements.

B. All field technicians handling refrigerant circuits must possess current EPA Section 608 Universal Certifications. Electrical modifications must be performed by an individual holding an appropriate, active license.

SECTION III – WARRANTY, CLOSE-OUT & BIDDING

3.1 Testing, Commissioning & Operational Acceptance

A. Upon final installation assembly, the contractor must conduct a complete, end-to-end commissioning routine across full heating, full cooling, and auxiliary heat strip modes.

B. Test readouts detailing dynamic system subcooling, superheat, line voltages, amp draws, and delta-T temperature profiles across supply and return systems must be demonstrated and documented in the presence of designated facility personnel.

3.2 Warranty Terms & Component Transfer

A. The entire system installation and all associated hardware items shall be fully warranted against defects in performance, materials, and field workmanship for a minimum dedicated period specified upon substantial completion.

B. All extended manufacturer warranties for critical system assets (compressor, coil structures, electrical parts) must be explicitly transferred to the state of Maryland at project closeout.

3.3 Close-Out Deliverables

Final payment clearance is dependent upon the successful handoff of the following materials to the DGS Project Manager:

1. Complete Operations and Maintenance (O&M) manuals.

2. Certified manufacturer warranty papers and component registration sheets.

3. Comprehensive parts replacement lists.

4. Signed, validated commissioning and startup logs verified by facility representatives.

3.4 Base Bid Framework & Procurement Outline

A. The Base Bid must reflect a comprehensive, turn-key total cost structure.

B. This price must encompass all field labor, specific tools, transport machinery, disposal fees, modern electrical wiring runs, the replacement low-GWP heat pump system, specialized heat breaks, and heavy-duty winter insulation additions.
