U89 PAC 03 and PAC 04 Replacement

The National Research Council of Canada is soliciting bids to replace two obsolete rooftop ventilation units, PAC 03 and PAC 04, at Building U89 located at 2320 Lester Road in Ottawa, Ontario. The original units, installed in 1977 and 2001 respectively, have exceeded their service life—one is nonfunctional and the other operates inefficiently under load—necessitating full replacement with higher-efficiency models. The scope includes demolishing and removing both existing units, modifying the roof structure to accommodate new unit sizes, installing new steel supports and curbs, and integrating the new equipment into the existing ventilation network. One unit will feature heat recovery capability to capture exhaust from washrooms and supplement building heating, while all systems must be fully tied into the Building Automation System (BAS) and equipped with a new Fire Alarm device for PAC 04. All materials must be delivered in original factory packaging with proper labeling, including ULC markings, product names, weights, and fire resistance classifications, and must be stored indoors in dry, clean, and well-ventilated conditions off the ground to prevent damage. Equipment must be CSA certified and comply with Canadian standards, and ULC or CSA registration plates must be provided. The contractor must hold a valid security clearance, and all personnel on site must meet corresponding clearance requirements, with site access denied to those lacking proper authorization. The solicitation requires submission of a bid security, performance bond, and labour and material payment bond using specified government forms, along with comprehensive insurance coverage including commercial general liability, builder’s risk, and pollution liability. All work must comply with Ontario and federal occupational health and safety regulations, with a dedicated contractor-supervised site presence at all times and mandatory use of personal protective equipment. Materials must be delivered outside of peak traffic hours unless approved. The contractor is responsible for scheduling and managing all project meetings, submitting agendas and minutes within strict timelines, and maintaining detailed financial and operational records to support auditability under federal procurement rules. Commissioning of the HVAC systems, building automation controls, fire alarm interlocks, refrigerant leak detection, and seismic restraints must be carried out in the presence of the Departmental Representative, with test procedures repeatable and verifiable, and performance documented through EMCS trending. Final acceptance requires completion of O&M training, submission of all technical documentation, and receipt of certification from authorities having jurisdiction, with a 12-month warranty period commencing upon issuance of the Certificate of Substantial Performance.
