The project ‘The Imperial’ consisted of an intricate excavation procedure in which conventional piling and anchoring was prohibited due to the development’s proximity to the RailCorp corridor. As per RailCorp guidelines, anchoring beneath the railway tracks is strictly prohibited to prevent rail tracks displacement.
Therefore, Alliance Project Group successfully coordinated the design and implementation of an alternative system to anchoring.
Alliance Project Group’s senior management team managed the design of a complex network of steel circular hollow section struts, spanning 25 metres in length. This complex strut system was utilised to support an 18 by 100 metre shoring barrier, directly adjacent to the RailCorp corridor.
In collaboration with ACE consulting, MYD consulting, Asset geotechnical and RailCorpauthorities, a sequencing procedure was developed in accordance with RailCorp guidelines, outlining an effective excavation method to minimise the temporary displacement of RailCorp assets. The strict implementation of this procedure was executed by ACE demolition and excavation and thoroughly supervised by Alliance Project Group, through the use of a multitude of monitoring devices, ensuring the overall displacement of RailCorp assets remains within the maximum displacement limit of 4 mm.
