Defence Construction Canada - Atlantic Region - Bedford, Nova Scotia

This appears to be an advance notice—not a bid request—for a potential modified design-build project to recapitalize the anti-armour range at 5 CDSB Gagetown in Oromocto, New Brunswick. Defence Construction Canada (Atlantic Region) identifies an approximate project value of $109 million and an anticipated solicitation posting in November 2026. The notice indicates that the project is conditional on Department of National Defence approval, and there is no guarantee that the contract will proceed. Potential work includes upgrading two firing-point areas; constructing four 2-kilometre firing lanes at each area, crossing lanes, berms, fire-base pads, tank-table positions, target-system electrical conduits, a multi-storey control tower, a sentry building, and an approximately 455-square-metre administrative building. UXO clearance, vegetation management, arc markers, and refurbishment of an existing control tower are also anticipated. Security requirements are expected. The anticipated clearance is Designated Organization Screening (DOS). Businesses that do not already hold the required clearance may be able to seek sponsorship through DCC’s Industrial Security Program. The notice says sponsorship should begin before the future solicitation is posted, but clearance sponsorship and approval are not guaranteed. A possible Indigenous-business participation component under the Procurement Strategy for Indigenous Business (PSIB) may also apply. The notice lists contract number HQ04022_86689 / 86689 CN. The tender record shows Bedford, Nova Scotia, while the described work is in Oromocto, New Brunswick; this apparent location discrepancy should be confirmed. Businesses considering this opportunity should review the complete official MERX notice and any later solicitation, confirm the actual closing date and requirements, assess their design-build capacity and security status, and contact DCC through its official security-process instructions before taking action. This notice alone does not establish that a business qualifies or that bidding is currently possible.Official source: https://www.merx.com/public/solicitations/4100377310/abstract?language=EN
