QEII Medical Centre - J Block - design and supervision of construction.
Prepared contract documents, supervised construction and checked private consultant work for a wide variety of projects throughout the state of Western Australia. The projects varied in size from multimillion dollar hospital complexes to schools, public amenities and police buildings.
During this period, managed the co-ordination of design on the latter stages of the eight storey prestressed concrete framed QEII Medical Centre. Co-ordination with a project management construction team was a critical consideration. Designed and supervised construction on QEII Waste Treatment Facility and alterations to the Plant Control facilities, QEII J-Block and numerous on site ancillary structures such as pedestrian and traffic bridges. Mr Dender was selected as a member of a committee commenting on draft changes to the forthcoming Standards Association of Australia concrete limit state design code.
Experience associated with the management of these projects included steel timber and concrete framed construction; concrete tunnel construction below water table level; control buildings for housing boilers, generators (emergency power) and electrical equipment; elevated steel tanks; cooling towers; plantrooms; steel bridge enclosures between buildings; large scale waste incineration plant; exhaust stacks; food processing and storage facilities, and a hydrotherapy pool complex.
