Hope Island Road Duplication
Hope Island Road is a major road that feeds into the northern end of the Gold Coast. It has a high traffic flow, and several businesses and landowners live and operate adjacent to or near the works. Hope Island Road has been progressively upgraded to a dual carriageway over the years, and the section from Cova Boulevard to Boykambil was the remaining section. The contract required installing two major sets of traffic signals at Crescent Avenue and the newly constructed Mervyn Thomas Drive.
The project was managed by Maroochy Shire Council as a joint funding partnership between Maroochy Shire Council and the QLD DMR. The works involved the construction of 2 bridges, (1 crossing live traffic), flexible pavement on and off ramps, stormwater drainage including RCP and RCBC drainage adjacent to live traffic and a wetland area. The location provided soft ground conditions where rock platforms were required to provide solid foundations on a large proportion of the site.
The Department of Transport and Main Roads identified that due to an increasing population of the Coomera area, the Motorway interchange at Exit 54 northbound had significant safety concerns for the public. These included long traffic delays for motorists and traffic queues that extended onto the motorway off-ramp during peak periods. A new link road was designed between the current Exit 54 Motorway northbound off-ramp, along with upgrades to the Abraham Road intersection.
The project involved the remediation of a decommissioned sand mine of approximately 120 hectares which had been overrun with pest flora and fauna species. Neumann Contractors was commissioned by Logan City Council to undertake the works involving the rehabilitation and revegetation of the area. A key objective of the project was to create a milestone development that provided a high level of commercial facilities whilst also improving the environmental value of the developed site.
Neumann Contractors was awarded the civil works contract for the Gold Coast Convention and Exhibition Centre project. The relocation of the major waterway, essential services and environmental issues presented some demanding challenges. This project brought its unique complexities as it involved several different concurrent tasks. Neumann Contractors acknowledge the civil work challenges were managed successfully due to the team approach with the builders and consulting engineers.
Kawana Waters was a significant development on the Sunshine Coast extending from north of Caloundra to south of Mooloolaba. The development includes a 2.5-kilometre recreational lake, two bridges, a navigable channel connected to the Mooloolah River, a lock and weir system, five kilometres of sub-arterial roads, numerous sub-divisional roads, approximately 1200 residential lots and a significant salinity rising main system. In addition to the work conducted for Lensworth, further work for Caloundra Council was completed in several soccer fields near the Lake.
The Bribie Island Road Project involved the construction of a new carriageway alongside the existing roadway. An existing roundabout was converted to a controlled intersection. The team also constructed a second controlled intersection. Significant Earthworks, Drainage and Electrical work formed a substantial portion of the contract. Particular attention was paid to pre-planning and methodology for the Earthworks specification as the area for works was susceptible to inundation during wet seasons.
As a result of monsoonal rain and numerous tropical cyclones across some areas of Queensland, the Department of Transport and Main Roads, road network sustained an unprecedented level of damage. This damage was further exacerbated and extended by the following years’ flood events. The Transport Network Reconstruction Program in the Wide Bay Burnett Region included reconstruction works in the Fraser Coast area surrounding the towns of Hervey Bay, Rainbow Beach and Maryborough.
The widening of Wynnum Road was required to help cater for the high volumes of traffic and peak-hour commuters that pass through the Wynnum/Preston/Randall Road roundabout each day. The works zone included various commercial outlets, a mix of residential properties and a school. These aspects were to be taken into consideration whilst completing the project. The immediate surrounding of the project included a number of regional shopping destinations, takeaway stores and shopping centre.
It takes time to adapt to new regulations and methodologies; however, the Chinderah Bypass contract saw Neumann Contractors placed in a situation that required experience that was yet to be gained. No precedence had been set, so a sharp learning curve was essential for the successful completion of the project. The Chinderah Bypass was a technically complex project that required a combination of best management practices and the conception of new industry practices to achieve the desired end.
The project was to hydraulically place 370,000 m3 of sand to raise the surface level of the Kingscoast Estate by 3 metres. The team dredged the sand from an adjacent sand quarry by the Nu Bounty, a 450mm bucketwheel cutter suction dredge combined with a 500mm, 2,000 hp booster pump. The slurry was pumped distances up to 2,000m through a 560mm poly pipeline to the estate. We achieved considerable savings and advantages over traditional methods.
The Kalimna Estate is a 32-hectare rehabilitation development of the old Tallebudgera quarry. The planning and design of the development area had to respond to the overriding criteria of a positive environmental solution. The quarry had to be re-contoured to eliminate steep gradients and the inner quarry face while retaining as much existing vegetation, providing a landscaping framework for residential development. The design provides for three passive and active recreation areas for residents.
The contract was for the construction of new service roads alongside the Mt Lindesay Highway in the Munruben-Park Ridge South area. The Mount Lindesay Highway is the key transport corridor between Brisbane and Beaudesert. The service roads were a precursor to the future four-laning of the Mt Lindesay Highway through this area by closing off all direct access to the highway from private properties and reorganising the flow of traffic between the highway and the local roads network.
The Beenleigh-Redland Bay Road between Cairns Street and Bryants Road interchanges is a vital transport link between Redland Shire and the M1 Motorway. The works included the full construction of a four-lane divided road, drainage and bikeway upgrades, route lighting and service road improvements. A significant element of the project was working adjacent to live traffic, carefully planned staging of the works and temporary works installations were vital in providing a safe work environment.
The Site forms part of a police academy and training facility at Wacol, adjacent to a prison and Brisbane River. The existing Site area consists of remnant urban bushland. The landscape intent is to provide a landscape scheme that is environmentally responsive and enhances the appearance of the proposed development. Locally native plant species are selected to provide long term visual interest through a planting scheme displaying a variety of colours, texture, form and seasonal interest.
The Parrearra Canal Crossing Project involved the construction of a 5 prestressed concrete bridge over the Parrearra canal in the new residential subdivision at Kawana Waters. Neumann Contractors was commissioned by Lensworth Kawana Waters Pty Ltd to undertake the project as part of the overall civil works for the development. Included in the project was the bridgeworks, including a prestressed concrete bridge structure and all the associated earthworks required to complete the structure.
