Westforce completed its scope on the Project in February 2024. A six-month design-phase was followed by a 10-month construction phase.

The Westforce scope included:

• Design of a thermally clad concrete tower structure incorporating installation of Azimuth and Seismic rings (rings designed and provided by others) and required to support the antenna dish, all to extremely tight tolerances
• Foundation design requiring excavation to reach sound rock at depth, mass concrete infill, concrete ring beam and stabilized sand backfill
• Structural design of the concrete tower itself incorporating ground slab, service trench, antenna equipment room and attic, mezzanine floor and access stairs as well as an adjoining entrance portico and “airco” shelter

• Design of all mechanical and electrical services to support the facility including chillers and air handling units
• Design of external civils comprising road access, concrete apron and drainage
• Construction of the concrete tower, including all foundation works and installation of cast-ins for mirrors and the critical free-issued Azimuth and Seismic rings

Construction of the remaining scope items, being electrical, mechanical systems, external civil finishing works, entrance portico, “airco” structure and cladding—has been undertaken by other contractors directly appointed by TAS.

Westforce's scope specifically excluded anything related to the antenna (the dish) and the scientific instruments and equipment necessary for its operation.
