26-58008 Fabrication of Heavy Impact Test Theater (HITT) Components, Question and Answer 4
Public summary
Generated or condensed from imported source text. Verify before bidding.
This appears to be an open National Research Council of Canada (NRC) requirement for fabricating and delivering components for its Heavy Impact Test Theater (HITT), used for full-scale ice-impact testing. The work potentially matches businesses with experience in precision steel fabrication, structural welding, machining, polyethylene and aluminum components, mechanical assembly, and fabrication to engineering drawings and demanding load and dimensional specifications. The main deliverables are: - A modular welded-steel hammer assembly, including 16 steel cube modules, stiffened plates, and internal load-transfer components. - A polyethylene and aluminum anvil assembly, including machined LDPE sheets, alignment rods, mounting hardware, and load-cell provisions. - A free-sway guidance system with steel frames, guide rails, and carriage assemblies. - A surge-restraint system with structural components, shock-absorber integration, and supports for repeated dynamic loading. The buyer is NRC’s Ocean, Coastal and River Engineering Research Centre. The listed locations include Newfoundland and Labrador and Ottawa, Ontario, although the tender information provided does not establish the required delivery or worksite arrangements. The tender has several amendments and question-and-answer documents, and the dates inthe supplied information are inconsistent: the record lists September 11, 2026 at 2:00 p.m., while the description mentions August 17, 2026 at 2:00 p.m. The latest amendment or official Canada Buys notice should be treated as controlling. Before considering a bid, review the complete RFP, all amendments and Q&A documents, engineering drawings, mandatory technical requirements, delivery terms, inspection and quality requirements, security or insurance provisions, pricing forms, and submission instructions. Confirm the current closing date and time directly in the official tender notice. This summary does not determine whether your business qualifies, and all details must be verified with NRC’s official documents before submitting a bid.

ALL OTHER TERMS AND CONDITIONS REMAIN THE SAME _______________________________________________________________________________________________________________________________________________________________________________ 26-58008 Fabrication of Heavy Impact Test Theater Components The National Research Council of Canada’s Ocean, Coastal and River Engineering Research Centre (NRC-OCRE) has a requirement for the fabrication and delivery of mechanical components for the NRC-OCRE’s Heavy Impact Test Theater (HITT). The requirement includes the manufacturing of a modular Hammer assembly, Anvil assembly, Free Sway System, and Surge Restraint System in accordance with NRC engineering drawings and specifications. BACKGROUND NRC-OCRE is developing the HITT to support full scale ice impact testing. The facility requires precision fabricated structural components including a modular hammer system, a polyethylene anvil assembly, and steel guidance and restraint systems. These components must be manufactured to meet specified design loads while maintaining modularity, durability, and repeatable performance during impact testing. This requirement will provide the fabrication and delivery of the primary structural assemblies required for the HITT facility. REQUIREMENTS The Contractor must fabricate, assemble where applicable,and deliver the following components: 1. Hammer Assembly The Hammer Assembly must consist of a modular welded steel structure designed for impact loading. The assembly includes: • A modular frame composed of sixteen (16) steel cube modules • Stiffened steel plates • Internal load transfer frame components All welds and structural elements must meet the dimensional tolerances and load requirements specified in the NRC drawings. 2. Anvil Assembly The Anvil Assembly consists of a modular polyethylene and aluminum structure designed to interface with the hammer during testing. The assembly includes: • Machined low density polyethylene (LDPE) sheets • Aluminum structural elements • Alignment rods and mounting hardware • Load cell mounting provisions Machining tolerances and surface finishes must comply with the specifications defined in the NRC drawings. 3. Free Sway System The Free Sway System provides guidance and controlled movement of the hammer assembly. The system includes: • Structural steel frame components • Guide rails and carriage assemblies • Mounting interfaces compatible with the hammer system The system must ensure stable alignment and controlled motion during operation. 4. Surge Restraint System The Surge Restraint System is designed to control impact energy and limit structural movement. The system includes: • Structural frame components • Shock absorber integration • Mounting hardware and structural supports The system must be fabricated in accordance with the NRC drawings and designed to withstand repeated dynamic loading. Please refer to tender documents for details. Closing date August 17, 2026 at 2PM EDT
