FAQs

What are the general requirements for reinforcement corners and cover unless otherwise noted?

All corners require 20x 20 mm fillets or chamfers unless otherwise noted. Where curing compounds are used, the cover is increased by 5 mm, and nominal cover tolerances must comply with the referenced standard table/specification.

Are contractors allowed to cut, bend, or weld reinforcement on site?

Reinforcement cutting or bending on site is not permitted unless shown on the drawings or approved. Heating or welding to reinforcement is not permitted unless shown on the engineering drawings, and permitted welding must meet the listed transport department specification section requirements.

How are discrepancies and engineering-document hierarchy handled?

Any discrepancies must be referred to the superintendent for resolution before proceeding. The specification hierarchy states that the engineering drawings take precedence over the specification, with the specification itself taking precedence over relevant standards when applicable.
