Screwpile Australia were one of the first contractors to commence work on this massive project.

One of the first requirements on site was to establish the Pioneer Construction Camp to accommodate the initial construction workers.  Project engineers Bechtel engaged mobile ‘donga’ manufacturer Desert Plains to construct a 100+ man accommodation village based on semi-trailer mobility.  These buildings consisted of accommodation and utility modules, water towers and sea container storage facilities.  All structures required cyclonic tie-downs due to the Region D Terrain Category 2 location. In these conditions the trailer based accommodation units developed large uplift and overturning forces, forces that needed to be transferred into the ground.  Bechtel engaged Screwpile Australia and Foundation Engineering to find a workable ground anchoring solution.

Donga anchor

A one size fits all approach, as is normally the case for tie-downs on mining camps was not going to work in this instance, as there were various building configurations and layouts developing different load case scenarios .  Interface connections between ground anchor and structure could not be bolted or a direct welded, so heavy duty chain assemblies needed to be designed and installed.

Detailed design drawings were submitted and approved for manufacture and construction.  Installation crews mobilised to site and worked on a crew rotation basis.  The project was installed and capacity performance tested in the scheduled time frame without incident.

Screwpile Australia were also successfully awarded a 400 x 300kN compression screwpile contract by Monadelphous for Wheatstone’s tank infrastructure contract.

ISO-9001 QA accreditation enabled us to successfully manage these projects through proven processes and safety management.
