Alder Constructions were contracted by the Silkwood Steiner School to prepare the existing site for the new high school campus and sporting fields. Major bulk earthworks of over 10,000m³ cut to fill was required, with over 1,000 lineal metres of retaining structures. GPS controlled machinery was used in order to increase works productivity and to achieve the tolerances required to the building pads and oval.

All required civil works were completed ahead of schedule by Alder Constructions for handover to the building contractors enabling works to be completed prior to commencement of the new school term.
