Defence Construction Canada / Construction de Défense Canada - Ottawa, Ontario
**Tender overview:** Defence Construction Canada (DCC) is seeking proposals from design-build teams for the design and construction of the Strategic Tanker Transport Capability Main Operating Base West (MOB-West) defence establishment at Edmonton International Airport, Alberta. The opportunity uses a modified design-build approach and has an estimated value of approximately **$450 million**. **Closing date:** November 24, 2026, at 2:00 p.m. The notice states that this date was changed from November 10, 2026, while the closing time remains unchanged. Proposals must be submitted electronically through MERX. **Potentially relevant businesses:** This appears primarily suited to large design-build teams or consortia with substantial defence, airport, infrastructure, engineering, architecture, and construction capacity. The listed roles include architectural, sustainable design, structural, mechanical, electrical, airfield electrical, civil, municipal, and airfield civil specialists at lead, senior, and intermediate levels. The full RFP should be reviewed for mandatory teaming, experience, bonding, insurance, financial, technical, and other requirements. **Important security requirement:** The selected contractor must hold a valid **Facility Security Clearance at the SECRET level**, issued through PSPC’s Contract Security Program. The notice indicates that further security details are provided in Amendment No. 1. **Other requirements:** The procurement is being conducted under the Canadian Free Trade Agreement, CETA, and WTO Government Procurement Agreement. Questions must be sent only to the official point of contact identified in the advertisement; contacting others during the solicitation period could create a disqualification risk. The tender record lists Ottawa, Ontario, while the work is described as being at Edmonton International Airport, Alberta. This apparent location discrepancy should be checked against the official MERX notice and RFP documents.
