roof and balcony at the same time. A considerable part of the order was to design and supply all forms for window and door openings, box-outs for the smaller cavities, bases with rubber sealants on both sides, adjustable stop-ends and even the toilet-base recess formers. All three moulds were designed and manufactured according to current standards, and they included hydraulically shrinkable and retractable inner cores and hydraulically moveable outside panels. To comply with local safety standards, the moulds had full steel working platforms with access stairs on the outside forms. Although the use of self-compacting concrete was assured from the start, Civmec insisted on having a limited number of electrical vibrators to be able to instigate the pouring process at all times. To guarantee a next day easy demoulding Construx provided accelerated curing by means of fans. Australia: Quadruple cell mould going to Melbourne Another Australian prison of which the cells were prefabricated with a Construx mould was the Chisholm Road Prison in Lara, Victoria. This maximum-security prison which was commissioned late 2022, accommodates 1,248 prisoners, and provides capacity for Victoria’s future growing prison population. John Holland, as Managing Contractor, subcontracted the production of the precast cells to Westkon, one of Australia’s major precast manufacturers. Construx supplied a ‘full option’ quadruple prison cell mould to their Melton yard in Cobblebank, Victoria. The Construx scope of works included design, manufacturing, pre-commissioning, supply, and commissioning of one quadruple cell mould in which the customer could cast a 4-room cell or a 2-room cell, complete with balcony. The assembly and installation of the mould was carried out by Westkon because no Construx technicians were allowed to enter the country due to the Covid-19 restrictions. To facilitate the installation, Construx provided detailed assembly and operation instructions as well as several series of photographs and videos of the assembly and pre-commissioning in the Construx facilities prior to the shipping. The multifunctional mould was made adjustable, to be able to cast any different wall thicknesses. The cell mould included following items: base frame, hydraulically shrinkable inner cores, hydraulically moveable outside panels, bases with rubber sealants on both sides and full steel working platforms with access ladders. Construx also provided supports and fixation systems for door and window frames, power points boxes, light switch boxes and light fittings, as well as adjustable boxouts with magnets for all other required cavities. Seen the mould was going to be used outside, Construx included steel pipes with outlets on the outside and the inside of the mould for heating and insulation on the outside mould. All hydraulic rams, electrical vibrators and electrical cabinets were fully connected and pre-installed, to reduce the installation time as much as possible.
