Key Construction Elements

A rollout of consecutive stages has ensured that SEE Civil has maintained sufficient resources to ensure ongoing delivery on multiple work fronts.
The ground conditions at Providence are varying with the most recent stages being predominately hard sandstone rock. During construction ripping, hammering, trenching, and blasting have been utilised to maintain program and deliver the work within the client’s stringent time frames.
