Case studies, our projects
Dedicated prayer rooms, promotion of multi-faith
religious traditions, including feast and special prayers
prior to TBM launches.
English language courses were made available to
help with the transition of personnel upon project
completion for UK business integration. The culture
established was crucial to the successful delivery of the
project.
Adding value
We optimised hydraulic profiling to increase flow
capacity by reducing friction and bends, which was
critical when introducing vertical curves in the onshore
tunnel.
The project’s carbon footprint reduction initiatives
included:
» The reduction of excavated material by the replacement
of 1.4km open cut with a tunnel.
»
Eliminating large plant required for open cut, selected as
dug material used for pipe surround and backfill
»
Recycled water for compaction and dust suppression
»
Use of local suppliers for Polycrete pipe and GRP fittings
manufactured 10km from site
»
Diverting from landfill 24,000m3 of tunnel arisings and
improved production outputs of 50% less time on site.
The project’s risk reduction initiatives included:
» The conversion from open cut to tunnelling, which
reduced plant movements

»
Fewer personnel working in excessive heat
»
Reduced volume of deep trenches
»
Tunnelling eliminated working near 1000 KV power lines
and multiple strategic water mains.
