Rebar construction 8 | Official - Sensitive - Commercial

Prototype Single prototype of a pit lid section to be manufactured initially to check manufacturing tolerances, lifting features and load bearing capability. RACE to have close collaboration with manufacturers to monitor challenges of assembly process Also part of the prototype package: • Locating ring • Reinforcement bar • Grapple test piece • Concrete pour For more information on prototype, see market enquiry. 9 | Official - Sensitive - Commercial

Prototype assembly The draft assembly sequence for the prototype: 1. 2. 3. 4. 5. 6. Welding 12 mm stainless steel plate into cladding sides Machine 40 mm base plate Place rebar cage onto base plate Install tie rods and grapple interface into base plate Weld up sides of cladding to complete outer shell Perform testing and inspection 10 | Official - Sensitive - Commercial

Full scope is to manufacture all pit lids once prototype has been completed. This is a separate procurement and call for tenders to be released at a later stage. 11 | Official - Sensitive - Commercial
