Citywide was recently awarded a major maintenance service contract for the provision of road resurfacing services to CityLink. Commencing April 8, the contract will initially involve Citywide performing extensive work to a number of sections on the Western Link sections of the network.
The scope includes road profiling, resurfacing (including the placement of 10mm SAMI spray seal), Dense Grade and Open Grade Asphalt, line marking, crack sealing, and traffic management. This capital works programme will occur on various sections of CityLink’s Melbourne network.
Citywide’s Infrastructure Manager Mike North said the CityLink contract win demonstrates the markets approval of Citywide’s extensive road maintenance and surfacing services.
“This win certainly highlights CityLink’s confidence in our professional expertise and more importantly, our ability to deliver large scale projects on time and on budget. It also confirms Citywide as a major player in the competitive roads maintenance sector,” said mike.
CityLink, Project Manager Ms. Elena Macaulay was pleased with the decision and looking forward to working alongside Citywide. “Having undertaken contract work for CityLink in the past, Citywide has always displayed high levels of professionalism and competency which has been illustrated in the quality of work produced. Again, they were able to provide CityLink with competitive rates, and a broad range of value added services. “
“As part of the works, both companies will be encouraged to achieve cost savings whilst maintaining high standards. Ultimately, our primary focus is to provide our customers with an efficient world class road network whilst minimising traffic disruptions,” concluded Elena.
Including main carriageways, ramps and emergency lanes, the 22 kilometre CityLink network has a total paved road surface area of approximately 800,000 m2. The current pavement consists of an Open Grade Asphalt (OGA) wearing course placed over a regulation layer of Dense Grade Asphalt (DGA) supported by a combination of concrete structures (i.e. bridges and culverts) and flexible pavements overlying natural soils.
The wearing course across the network has been in place since CityLink commenced operation in 1999. After twelve years of extensive use and following a comprehensive study, it was decided that the network undergo rehabilitation works to bring it back to its original world class standard.
Encompassing approximately 200,000 m2 or 25% of the total CityLink surface area, the initial stage of the road works is scheduled for the Western Link of the network from Bell Street to Moreland Road and some ramps of the Bolte to Westgate interchange.
Additional works will also include the replacement of Weigh-in Motion pads located under the ‘Yellow Beam’ gateway feature into Melbourne, the Power Street bridge abutment pavement rehabilitation works, and the completion of the Southern Link resurfacing works.
Over the next 24 months, the projected scope of this contract is estimated to be in the vicinity of 400,000 m2 of asphalt works.
Profiled to a depth of 50mm, CityLink’s road specification requires a 20mm base of Dense Grade Asphalt, finished with 30mm Open Grade Asphalt, followed by the full reinstatement of all line marking including the toll gantry points. In sections of the network which are showing signs of extreme cracking, 65,000 m2 of a 10mm SAMI-seal will be used before the placement and compaction of the dense grade and open graded asphalt.
The person who will manage the delivery of Citywide’s services to CityLink is Asphalt Business Unit Manager Damien Hodge. Commenting on the new opportunity, he emphasised that Citywide’s “strong track record in the successful delivery of critical infrastructure initiatives throughout Victoria was a contributing factor in securing this contract. I am very excited with the opportunity that CityLink has provided Citywide, and am keen to demonstrate the capability of our people to deliver a quality outcome to such a high profile client.”
