Contractors must provide all labor, materials, and equipment for demolition, installation, gas line reconnection, electrical work, thermostat installation, and system testing, with work completed within 30 working days and compliance with all applicable federal, state, and local codes. The government will evaluate proposals using a Lowest Priced Technically Acceptable (LPTA) methodology across four subfactors: form completeness, pricing, technical approach, and documented experience with recent relevant references.
