D2. SCOPE OF WORK
D2.1 The Work to be done under the proposed Contract shall consist of commercial and industrial HVAC services which includes the installation, maintenance, repair, and replacement of heating, ventilation, and air conditioning systems, including but not limited to air handling units, furnaces, rooftop units, chillers, ductwork, thermostats, ventilation equipment, and control systems in City owned and/or operated buildings at the direction of the Contract Administrator for the period of September 1, 2025, to August 31, 2028.
D2.1.1 The City may negotiate the extension option with the Contractor within ninety (90) Calendar Days prior to the expiry date of the Contract. The City shall incur no liability to the Contractor as a result of such negotiations.
D2.1.2 Changes resulting from such negotiations shall become effective on September 1 of the respective year. Changes to the Contract shall not be implemented by the Contractor without written approval by the Contract Administrator.
D2.2 The major components of the Work are as follows:
(a) HVAC System Inspections, Maintenance & Repair:
(i) Maintenance & Emergency Repair services for heating and cooling systems including rooftop units, air handlers, split systems, chillers, and boilers; addressing issues such as component failures, airflow loss, or lack of temperature control.
(ii) Repair or replacement of malfunctioning components such as compressors, blowers, motors, thermostats, and sensors, including issues with no heat, no cooling, or irregular operation.
(iii) Inspection of HVAC systems for refrigerant leaks, electrical faults, mechanical wear, and duct obstructions; performing necessary repairs to restore system performance.
(iv) Inspection & regular cleaning of condenser and evaporator coils, fan blades, blower wheels, and drain pans to ensure optimal heat exchange and air quality.
(v) Clearing and cleaning of condensate drain lines, traps, and pans to prevent water overflow, mold growth, and system shutdowns.
(vi) Testing & inspection of control systems and safety devices, including limit switches, pressure sensors, flame detectors, and gas valves to ensure safe operation.
(vii) Troubleshooting and resolution of system issues such as insufficient airflow, temperature imbalance, thermostat inaccuracy, or unusual noise/vibration.
(viii) Repair and maintenance of air conditioning units, furnaces, and heat pumps, including verification of proper operation of thermostats, fans, burners, and ignition systems.
(ix) Replacement or repair of key HVAC components such as belts, pulleys, contactors, capacitors, relays, and electrical terminals.
(x) Addressing airflow restrictions or ventilation issues in ductwork systems, including blockage removal, damper adjustment, and air balancing.
(xi) Inspect, clean, or replace air filters, fan belts, and drive assemblies as needed to ensure optimal airflow and mechanical reliability.
(xii) Refrigerant management and leak detection, including checking system pressures, repairing leaks, and recharging refrigerant to manufacturer specifications and environmental regulations.
(xiii) Filter and Air Quality Maintenance: Clean or replace air filters in HVAC systems and inspect indoor air quality components such as humidifiers, dehumidifiers, and UV purifiers.
(xiv) Heating & Cooling Equipment Inspection: Check boilers, chillers, furnaces, and air conditioning systems for operational efficiency; test temperature differentials, inspect combustion chambers, and verify exhaust venting for safe operation.
(b) Project Work (Installation, Upgrades and Replacement)
(i) New HVAC System Installation: Install complete HVAC systems including ductwork, controls, ventilation, and major equipment (e.g., RTUs, split systems, VAVs, chillers, boilers) for new buildings or additions.
(ii) System Replacement and Retrofits: Remove and replace outdated or non-functional HVAC equipment with new, energy-efficient models, including electrical and control upgrades as required.
(iii) Ductwork Installation and Modification: Design, fabricate, and install new duct systems or modify existing ductwork to improve airflow, zone control, and ventilation efficiency.
(iv) Building Management Systems (BMS): Install or upgrade HVAC control systems, including thermostats, building automation system (BAS) integration, sensors, actuators, and zone controllers.
(v) Ventilation and Air Quality Projects: Implement fresh air intake, exhaust, and filtration upgrades to improve indoor air quality, meet regulatory standards, or accommodate facility changes.
(vi) Energy Efficiency Upgrades: Install high-efficiency units, variable speed drives (VSDs), energy recovery systems, and smart control systems to reduce energy usage and improve system performance.
(vii) Equipment Relocation or Reconfiguration: Move or reconfigure HVAC units and associated infrastructure due to building renovations, changes in floor layout, or equipment upgrades.
(viii) Commissioning and Performance Testing: Conduct full system startup, testing, and balancing after project completion to ensure proper installation and operational performance according to specifications.
D2.3 The Work shall be done on an “as required” basis during the term of the Contract
D2.3.1 The type and quantity of Work to be performed under this Contract shall be as authorized from time to time by the Contract Administrator and/or designate.
D2.3.2 Notwithstanding C7.4, the City shall have no obligation under the Contract to purchase any quantity of any item in excess of its actual operational requirements.
