Questions Due Date: Oct 19th 2022, 5:00 PM EDT The Department of Public Utilities (DPU), Division of Sewerage and Drainage (DOSD) has identified numerous HVAC & Air Purification systems that are nearing the end of their useful service life and are becoming increasingly difficult to repair and maintain. This work for the DOSD is part of the City's continuing program to upgrade its treatment facilities, provide efficient, reliable, cost-effective operations, and enhance personnel safety. This contract will provide engineering services necessary for the planning and design for replacement, refurbishment, or installation of new HVAC and air purification systems. This contract will have multiple small capital improvement projects that each may include: site investigations, inspections, and evaluations of existing conditions; technical report writing; assistance with contract sequence planning; preparation of engineering or architectural drawings; documents/drawings for permit approval; specifications; bid documents, bid conference meetings, site tours, and other assistance during bidding; preparation of record plan drawings; preparation of M & O Manuals; equipment training for plant staff; HVAC control systems access software and tools; and technical project representation during construction. The Offeror must have experienced personnel and equipment for performing this work. The design of the HVAC & air purification systems at DOSD facilities may include items such as structural repairs, relocation of ductwork and rooftop equipment, rooftop repair, asbestos surveys and abatement, and any other work ancillary to providing a fully functioning HVAC and/or air purification system. The equipment specified will vary based on site conditions, building use, building permit requirements, and ease of maintenance issues. Consideration shall be given to increasing ease of maintenance, standardization of operating systems, and specifying HVAC control systems access software. The HVAC & air purification systems shall conform to current regulatory and building codes and be designed sufficiently for current or changing building needs. These services are required for all DOSD facilities. DOSD operates and manages the Southwesterly Compost Facility (Compost), Sewer and Maintenance Operations Center (SMOC), multiple sanitary and stormwater pump stations, collection systems, and two Wastewater Treatment Plants: Jackson Pike (JPWWTP) and Southerly (SWWTP). This will be a one-year contract, with an option for the City to renew annually for an additional two years. Adjustments to fees and scope will be made by contract renewal based on annual proposals or as requested by the City. The duration of the contract may extend into subsequent years based on the complexity and progress of the assigned work. The method of Contractor Selection has not been determined at this time.
