Contract Description

​

Excavation of 1,100 m3 of site material to a depth of 4.0 m to allow the installation of two large in ground fuel tanks and on-site stormwater pads.  Base installed the reticulated pipeworks and services with Mansfield Installations and backfilled /fabric wrapped with approx. 750 m3 of drainage gravel.

​

In the centre of Arrowtown a small piece of commercial land was transformed into a small self service fuel station by RD Petroleum.  Base tendered for the excavation, backfill, tank & services installation and site finishing through Mansfield Installations and commenced works in September 2015.  The site was very public, and very challenging to work in but the job was very successful and was good for Base’s local profile.
