Tonkin Consulting was engaged by the Thiess-Macdow joint venture to provide proof engineering services for the Seaford Rail Extension.
The joint venture design team provided Tonkin Consulting with several design packages to verify the design against the requirements in the brief and the appropriate design standards.
Design packages included three road/rail bridges, two depot buildings, internal roads and shared use paths, stormwater drainage for the whole corridor, road safety auditing in five stages and building certification. Each package was provided at 30%, 85% and 100% design stages. Verification comments and calculations were provided back to the joint venture within two weeks of receipt.
A road safety audit of the Seaford Road bridgeworks was also undertaken by Tonkin Consulting to assess road crash potential at this location. In particular the pedestrian refuge east of the fire Station and retirement village access.
