Schenck – Site 207 Jandakot

PS Structures was engaged by Jandakot City Pty Ltd to design and construct a warehouse for Schenck Processing.

The design was challenging and commenced early December 2018. An existing Schenck facility in Hazelmere and design brief were used as a reference for this design.

Specialised plant and equipment were to be relocated and retrofitted into the new facility by Schenck after practical completion was granted.

The floor areas are:

  • Office – 1,300m2
  • Warehouse/Workshop – 10,560m2
  • Wash Bay -144m2
  • Land Area – 39,000m2

The new workshop facility is 176m long, which is split into 3 bays. Workshop bay 1, workshop bay 2 and the warehouse racking section. An independent internal office, with an area of 240m2, was constructed within the workshop to cater for staff that were working within the facility. This structure included toilets and a lunchroom.

Workshop bay steel was designed to accommodate overhead gantry cranes with a clear under hook height of 8m. Gantry cranes included 4 x 40t and 4 x 5t which would run independently on specially designed crane beams, to move large screens to separate stations within the warehouse.

External walls included dado concrete panels with textured paint and colorbond cladding above, to clad the steel portal frame and purlin constructed structure. Design was onerous on the positioning of steel columns to meet the internal equipment and circulation requirements. Stations within the structure included paint booths, test beds and water and sand blast rooms, some of which were designed to accommodate jib cranes.

A requirement from Jandakot City was the 200mm fibre reinforced slab was to be poured after the walls and roof had been completed, to ensure it was carried out in a controlled environment with no damage to the slab being incurred.

Design loads to the slab catered for a minimum of 10 tonne forklifts (dual axle load), 55tonne machinery load (5.5m x 13m) and/or 6tonne on (1.5m x 5m). There were numerous electrically operated roller doors around the warehouse with wind locks, designed for access of large screens.

The warehouse structure, due to its size and fire engineering requirements, was designed to accommodate fire sprinklers.

Test bed concrete slabs were designed within the workshop to withstand large forces from shaking/vibrating plant and equipment. These were constructed from fibre reinforced concrete and mesh, generally referred to as ‘combi slabs.’ Construction was demanding as halfen channels were required to be cast accurately within the mesh and concrete fibres.

An external fibre reinforced concrete hardstand slab was constructed, 150mm in depth laid on 150mm thick limestone base, this design is rated for 100 tonne loads.

An external office was constructed from a combination of a powder coated aluminium framed wall system, masonry and/or light weight framing. This included other facilities such as; toilets, kitchen/tea prep area and a lunchroom with adjoining covered al-fresco area. A 5000m2 bitumen car park was constructed to accommodate staff parking.

Construction commenced at the end of January 2019. Schenck advised a sand and water blast room would need to be designed and constructed for the treatment and refurbishment of large screens. Due to the time implications on the project, construction could not be delayed consequently
PS Structures and Schenck worked together to evolve the design of the independent sand and water blast rooms during construction.

Specialist subcontractors were engaged directly by Schenck for the fit-out requirements of the sand and water blast machinery. Design was complex and lengthy as Schenck were not aware of the requirements in these rooms and dealt with the specialist contractor directly. The sand and water blast rooms were installed after the main portal frame for the workshop was erected.

Construction was completed and practical completion received in April of 2020.
