Gold Coast Water Recycled Water Mains ReplacementDesign of a replacement of a Y junction. This project required high dimensional accuracy as the shutdown window was short. This was achieved using laser scanning of the existing pipe, then scanning of the constructed pipe in the workshop. This scanned data was then input into the model to check the manufacture of the pipe before dispatch to site. The construction was performed without any site modification.
Beechwood Water Supply Pipeline DesignCivil design and documentation of a new water main approximately 6km in length from the existing Rosewood reservoir to Beechwood village. The main included approximately 410m of DN600 DICL and approximately 5400m of DN200 (various materials), including an under bore of the Hastings River.
Pormpuraaw Reservoir Design and DocumentationTender design and documentation of the concrete reservoir including SCADA upgrades, gas chlorine dosing system, site earthworks/landscaping, and galvanised steel framed roofing. Pormparaaw is a remote indigenous community in Far North Queensland.
Palm Island Water SupplyGANDEN was engaged to assess the capacity and condition of the existing Palm Island water supply infrastructure including the: - Water supply dam capacities and operation, The water treatment plant and The water distribution network, including producing a network model. As part of the town water and sewerage infrastructure review, GANDEN also reviewed the sewage treatment plant and sewerage network.
Oxley Highway Pipeline Relocation DesignCivil design and documentation for relocation of the various pipelines to cater for the Oxley Highway upgrade inland from Port Macquarie. Works included pipeline civil design, hydraulic modelling, specification writing and organising survey, geotechnical and potholing.
QUU Potable Water BoostersOptions analysis and detailed design of 2 replacement potable water booster pump stations located in Ashgrove and Toowong in Brisbane. The existing pump stations remained operational during the construction period, with only a small window available for change over. The new pump stations were designed to allow for construction to be completed before the existing pump stations were taken off line. Both pump stations are located in constrained spaces within road reserves and in close proximity to existing houses, parkland and the Toowong cemetery. Consultation was undertaken with the Council arborist and parks officers to ensure the protection of existing trees and to select a location which minimised the impact on public amenity. A low profile retractable acoustic cover was incorporated into the design to provide weather and and vandalism protection and to minimise the noise and visual impact on the surrounding residents. In order to accommodate large variances in flow rate and head, a 4 pump arrangement was adopted at both sites, with one small jockey pump for overnight low flow periods and 3 large pumps for day time and fire flow operation.
Gilston Reservoir ReclorinationThe City of Gold Coast (Gold Coast Water) required a re-chlorination facility on its reservoir at Gilston. GANDEN provided the concept design and documentation and assisted Gold Coast Water throughout the detailed design review and construction period.
