The City of Kingston has awarded $7.1 million in tenders for Mordialloc-based projects, including Stage 2 of dredging at Mordialloc Creek, sheet pile installations at Lambert Island and Mordialloc Shopping Centre streetscape works.
The $5.56 million tender for Stage 2 of the Mordialloc Creek dredging project was awarded to Thiess Services. The project will involve dredging from the mouth of Mordialloc Creek to the Governor Road Boat Ramp. The volume of material to be removed is anticipated in the order of 9,000m3 of silt.
Dredging will improve the health of the waterway, as well as providing access for the boating community who have been unable to navigate the creek at low tide.
Dredging is expected to begin in April, after Easter, and be completed in November 2012. The community will be kept informed and updated during the works. In addition, Council will continue to consult directly with the Mordialloc Creek Boating community and the Mordialloc Creek Advisory Committee.
Due to the large scale of Stage 2 of the project, a works area will be established at Attenborough Park to unload sediment and contain equipment. The shared pedestrian and cycling path will be diverted around the worksite.
Stage 1 of the dredging process involved dredging and associated works on moorings around Lambert Island and was completed last year. The creek last underwent major dredging in 1997 and 1973.
The $732,600 tender for sheet pile installation on the northern wall of Lambert Island was awarded to Bridge & Civil Pty Ltd. The installation works will proceed in parallel with Stage 2 of the Mordialloc Creek dredging program and are expected to be completed in August 2012.
The new sheet wall will widen the main channel of the creek and allow for additional mooring places and a pontoon landing for small boat launches.
The design life of a new sheet pile wall is approximately 50 years using vertical, interlocking steel sheets with block capping.
Last but by no means least, the $815,147 tender for streetscape works at Mordialloc Shopping Centre was awarded to CDN Constructors Pty Ltd.
The project will include replacing footpaths and street furniture, landscaping, upgrading the stormwater drainage pipe and pit, constructed indented parking bays and installing street lights and traffic signs.
