Welding Services

Natural Resources Canada is seeking qualified contractors to provide specialized welding services including the installation and modification of welded pressure piping and tubing, as well as the repair and alteration of pressure vessels, at its Bells Corners Complex in Ottawa, Ontario. Work will be performed both in the contractor’s facility and on-site, requiring compliance with Canadian Standards Association CSA B51 and the Technical Standards and Safety Authority Boiler and Pressure Vessel Code, with the more stringent requirement prevailing in case of conflict. The contract spans from its effective date through March 31, 2027, with an irrevocable option for up to four additional one-year extensions under identical terms. Bidders must demonstrate technical compliance through mandatory criteria: a fabrication shop located within 125 km of the Bells Corners site, valid TSSA certifications for both boiler pressure vessel repair and process piping installation, and submission of complete documentation proving adherence to all technical requirements. The award will be made using a Lowest Price Technically Acceptable approach, where only technically qualified bids are considered, and selection is based solely on the lowest total estimated price covering both base and option periods. All proposals must be submitted electronically via Canada Post’s CPC Connect service by the May 28, 2026 deadline, with no alternative submission methods permitted. Contractors must maintain a valid Designated Organization Screening from the Contract Security Program and ensure all personnel accessing the site hold at least RELIABILITY STATUS clearance. Indigenous-owned businesses qualifying under the definition of ≥51% Indigenous ownership and control are invited to bid, but must commit to performing at least 33% of the total contract value through Indigenous entities. The contract includes strict security protocols governed by Annex C and the Contract Security Manual, requiring adherence to safeguarding procedures for protected and classified information, with subcontracting involving security-sensitive work requiring prior written approval. Invoicing must be submitted via email in PDF format only to Invoicing-Facturation@nrcan-rncan.gc.ca, with no use of WAWF or IPP systems. Performance occurs exclusively at the CanmetENERGY-Ottawa facility located at 1 Haanel Drive, Ottawa, where the Government will conduct all inspections and final acceptance of work. The contractor is obligated to follow the Site-Specific Health and Safety Plan, use only new original materials unless equivalent certified substitutes are approved, and comply with the Canada Labour Code and Occupational Health and Safety Act. Termination for default may occur if the contractor relocates outside Canada or fails to meet Indigenous business
