Civil / infrastructure

 

Holcim excels in supplying concrete to bridges, dams, major roadway, water treatment and other infrastructure projects. These projects often require significant planning, co-ordination and development work. At Holcim we can meet the challenges of technically and logistically difficult projects.


Brisbane Inner City Bypass

The project involved the construction of a four to six lane 4.5km motorway that links Hale Street at Milton to Kingsford Smith Drive at Hamilton and includes Queensland's first land bridge linking Victoria Park and Gregory Terrace parklands, a 400m six lane cut and cover tunnel through the RNA Showgrounds, and a series of viaducts and bridges crossing over existing major arterial roads, rail lines and creeks.

Cosmos Nickel Mine

Cosmos is a nickel mine situated about 500km north of Kalgoorlie, Western Australia where temperatures through summer are often over 45˚C. The nickel ore is mined using a technique involving downward long hole drilling methods. The resulting by-product of this method is a large hole (a stope) of dimensions approximately 50m x 50m x 50m. The specification required that the underground fill would flow, set and achieve a 3MPa strength criterion.

Cowal Gold Mine

Holcim's promise of strong operational capability, technical support, and an overall focused team led to a major contract being won for (mobile plant) concrete supply required for the development of a large open cut gold mine: the Cowal mine site in Central Western NSW. A large depth and mass required careful planning, mix design and placement to control the potential for high temperature gradients to develop. Large temperature differentials would make thermal cracking a possibility.

Eastern Distributor

Sydney's $700 million Eastern Distributor was one of the largest civil construction projects in Australia, designed to provide a direct link between the city's northern and southern suburbs. One of the factors that contributed to completion ahead of schedule was the extensive use of precast concrete throughout the project in both civil and structural applications. Humes supplied the bulk of the precast concrete components and Holcim supplied in excess of 40,000m3 of premixed concrete to the project.

Epping Chatswood Rail Line

In Sydney, the Main West Rail Line and the Main North Rail Line were currently operating close to capacity. The NSW government awarded the Thiess Hochtief Alstom group an $850 million contract for major tunnelling and track works on the Epping to Chatswood component of the Parramatta Rail Link project to alleviate this congestion. Readymix (now Holcim) was awarded the contract to supply major structural components within this project that includes two tunnels each 13km long and four stations.

Graham Farmer Freeway

This major project included the construction of a 1500m, 6 lane tunnel (3 carriageways either side) totalling 7km of freeway connecting East to West Perth. Construction of the Northbridge Tunnel commenced on the west side of the Perth city area. Holcim supplied the concrete from their East Perth plant, with Osborne Park and Welshpool as backups. Around 2,000m3 of concrete was produced daily with production starting around 3.00am most mornings.

Lane Cove Tunnel

The project is part of Sydney's orbital road network and involved the construction of a twin 3.6km tunnel plus 3.5km of bridge and road upgrades to link the M2 Motorway with the Gore Hill Freeway. The project required over 256,000m3 of concrete and included two new lanes across the Lane Cove River and transit lanes on the Gore Hill Freeway. Challenges of the project included the difficulties of working on a route that caters for around 90,000 vehicles a day and the requirement that there be no reduction in the number of traffic lanes during peak hours.

M7 Orbital

The Roads and Traffic Authority of NSW engaged Westlink Motorways to design and construct the M7 Orbital ring road around Sydney. The concrete had critical specification requirements: bridge mixes, paving concrete and tremmie mixes, lean mix and high early strength concrete. A high degree of concrete testing and significant logistical activity and analysis were required, and logistical difficulties were addressed in supplying concrete materials to such a vast construction area.

Roxby Downs

A major expansion of Australia's largest copper and uranium mine, 560kms north of Adelaide, included a new shaft to bring ore to the surface, extensions to the refinery and mill facilities, a new smelter, and underground crushing plant and rail line. To achieve the demanding production requirements in this very remote environment, Holcim established two computerised batch plants on site that operated 7 days a week 24 hours a day for almost two years.

Tugun Bypass

The Tugun Bypass project involves the construction of a new 7km motorway that will stretch from Currumbin in Queensland and pass west of the Gold Coast airport's main runway to join the Tweed Heads Bypass in NSW. Due to environmental considerations in the area, approximately 2km of the bypass crosses airport land parallel with the main runway, requiring the construction of a tunnel to avoid interfering with airport operations and runway extensions.
