Defence Construction Canada / Construction de Défense Canada - Ottawa, Ontario

This tender appears to be a major design-build construction opportunity from Defence Construction Canada for the Halifax Heating & Municipal Services Upgrade (HHMSU) at CFB Halifax, Nova Scotia. The closing date was amended to September 17, 2026 at 2:00 PM, and proposals are to be submitted through MERX. The project is described as a modified design-build procurement with an estimated construction value of about $550 million. It seems to involve a wide range of design disciplines, including architecture, structural, mechanical, electrical, civil/municipal, sustainability, BIM, and related technical roles. A key requirement noted in the notice is a valid Facility Security Clearance at the SECRET level issued by PSPC’s Contract Security Program, so this is an important item to verify early. The solicitation also says questions must go only to the named contact in the official notice. As always, the official MERX notice and amendment documents should be reviewed carefully before deciding whether to bid.

Defence Construction Canada / Construction de Défense Canada - Ottawa, Ontario

This appears to be an open Defence Construction Canada opportunity for a design-build team to design and construct multi-unit residential housing for the Canadian Forces Housing Agency in Yellowknife, Northwest Territories. The work uses a modified design-build approach and has an estimated value of approximately $12 million to $18 million. The opportunity may be relevant to a contractor or consortium able to provide both construction and multidisciplinary design services. The listed roles include a design team lead, architects, structural, mechanical, electrical, civil/municipal engineers, urban planners, and architectural or engineering technologists, technicians, and draftspersons. Hourly rates appear to be requested for these positions. The tender is being competed through the MERX Electronic Bidding System. The listed closing date is September 17, 2026, at 2:00 p.m.; the notice shows earlier closing-date changes, so the current MERX deadline should be confirmed. Although the record lists Ottawa, Ontario as the location, the described project is in Yellowknife, Northwest Territories. Questions must be sent only to the point of contact identified in the official solicitation, as contacting others could create a disqualification risk. Applicable trade agreements include the CFTA, CETA, and WTO-GPA. Before deciding whether to bid, review the complete RFP and all amendments on MERX, including mandatory qualifications, bonding and insurance, Indigenous or northern participation requirements, design standards, construction schedule, site conditions, security requirements, submission instructions, and team or subcontractor requirements. This summary does not establish eligibility; the official tender notice and RFP must be verified before submitting a proposal.Source: https://www.merx.com/public/solicitations/3975611901/abstract?language=EN
