Welcome to Winslow

Ballarat Western Link Road

Sub-Heading to project name: BWLR Project
Business Units: Infrastructure
Location: Ballarat, Victoria
Client: City of Ballarat
Industry Sector: Local Government
Others Solution: Major Road Projects, Utilities, Plant and Equipment, Surveying, Traffic Management
Key Achievement :
- Improved methodology and cost savings. Due to the limited tight working space between the bridge RE walls and the railway, the decision was made to seek a temporary works design that allowed an access gantry to be hung from the column abutments. This decision resulted in a saving on cost in lieu of extensive scaffold hire costs and made the methodology of placing the bridge beams with a single crane in lieu of a dual crane lift possible.
- Reduced project delivery time. Winslow found opportunities to reduce project delivery time through the construction of the Off-Structure Barrier (OSB) capping beam through two avenues: utilising the verge in lieu of one side of formwork and pre-fabricating the capping beam cages remotely in the project site compound.
- Successful bridge beam lift. utilising a 280T crawler crane for the lift, Winslow Infrastructure successfully undertook complex operations within the rail corridor, minimising disruption and within the planned occupation constraints.
- Minimal environmental footprint. the area of works had a population of Growling Grass Frogs which Winslow Infrastructure actively took measures to protect through its construction environment management plan.
- Community and stakeholder engagement and communications. Winslow collaborated with the City of Ballarat and the Wathaurung Aboriginal Corporation to ensure culturally sensitive sites along the road alignment were respectfully and effectively managed, whilst adhering to numerous environmental protection measures.
- Complex project management. V/Line required Winslow to demonstrate extensive planning methodology and safe work practices for approval to commence works within the rail corridor. The City of Ballarat, Winslow, V/Line Railway Safety Personnel and Representatives held and attended various workshops to ensure construction activities met the criteria of all stakeholders.

This project involved delivering a two-lane, 3.2-kilometre long road between Remembrance Drive and Liberator Drive. Roadworks included in excess of 150,000m3 of bulk earthworks and associated services including drainage, pavement construction, asphalting, road sealing, line marking, sign installation, and lighting.

The scope of works also included re-alignment and re-construction of 1-kilometre length of Blind Creek Road, building a new single Span bridge overpass of the Ballarat-Ararat Railway and a combined wildlife- and- drainage crossing (18 multi-cell culvert structure) for Mullawallah Wetlands (Winter Swamp).

Additionally, Winslow Infrastructure upgraded traffic lights at one intersection, relocated assets (Telstra, Central Highlands Water, Ausnet and Powercor) and constructed a shared walking and cycling path.

Dohertys Road

Business Units: Infrastructure
Location: Laverton North, Victoria
Client: WBHO Infrastructure Pty Ltd
Industry Sector: Transport
Others Solution: Major Road Projects, Utilities, Surveying
Key Achievement :
- Complex Project Management. This duplication is considered one of the most difficult brownfield road projects ever undertaken in Melbourne. The site sits among many large-scale businesses with extensive, private utility infrastructure. All excavation along the alignment required service proving that was collated within a 3D BIM model. This facilitated clash detection that was the cornerstone of our permit processes for in-ground and overground works.
- Service Relocation. Our team worked in the vicinity of the high-pressure Liquide Air pipelines, the 66KB high voltage APA gas transmission line and the heritage-listed Melbourne Outfall Sewer. The 600mm MSCL Western Watermain was relocated to accommodate bridge abutments. Winslow’s dedicated utility team worked through modifications, protections and redesign for 18 months so that the works could be completed safely.
- Structures. A 60m steel truss bridge with architectural cladding was designed to provide for Federation Trail pedestrian and bicycle traffic over the Dohertys Road alignment. Further to this, a complicated five-span bridge was built within the Princes Freeway alignment, with Winslow nominating pre-cast elements for piers, cross-heads and abutments to minimise impacts between plant, personnel and the travelling public in the constrained environment.
- Safety. With utilities management being a key risk for the project, a number of safety initiatives were developed on Dohertys Road, including the implementation of overhead gantries for protection of overhead services and improved excavation permit processes.
- Environment and Sustainability. Winslow focused on recycling of products and natural resources throughout project delivery. This included recycling of piling water for use in dust suppression, as well as capturing and using rainwater for washing down pavements and equipment. Silt basins were constructed to manage the NDD and wastewater from site, with slurry and water treated with a solidification agent then dried out and reused as fill. Excavated rock was crushed for reuse in retaining walls and abutments, and soil was recycled for use in landscaping works. Crushed glass sand was also used instead of using natural resources (river sand) for NDD and subsurface drainage works.

This $92M project involved upgrading Dohertys Road from Fitzgerald Road to Grieve Parade in Laverton North to improve access to key freight routes and industrial areas.

Project works included construction of a significant five-span bridge over the operating Princes Freeway, approximately 4km of arterial road duplication in a heavily industrialised area, and extensive service relocation and protection works. Major intersections were upgraded with new signalised intersections at Fitzgerald Road and Hume Road, and new roundabouts at Gordon Luck Avenue, Cherry Lane and Cyanamid Street.

Lathams Road

Sub-Heading to project name: Part of the South Eastern Roads Upgrade Project
Business Units: Infrastructure
Location: Carrum Downs, (Melbourne’s southeast)
Client: Major Road Projects Victoria (MRPV)
Industry Sector: State Government
Others Solution: Major Road Projects, Utilities, Plant and Equipment, Surveying, Traffic Management
Key Achievement :
- Utilities relocation. Winslow challenged the reference design on numerous occasions, collaborating with MRPV to achieve significant scope reduction for utilities relocation scope across multiple USP’s. This helped to remove critical path utility relocation works and provide value for money outcomes in redesign.
- Thinking outside the box. in developing an option to replace the Boggy Creek drain, instead of providing a ‘like for like’ box culvert, Winslow has developed a piped solution that will reduce construction time and minimise disruption to stakeholders.
- Environmental and sustainability management. The project was certified at an ‘Excellent level’ for its ‘As Built’ Rating from the Infrastructure Sustainability Council. The team also developed, trialed, and implemented several innovations for the industry including Polyrok, a recycled plastic aggregate.

The Lathams Road Upgrade project duplicated Lathams Road and Rutherford Road and widened roundabouts at Oliphant Way and Frankston-Gardens Drive. In addition, two intersections at Stephenson and Colemans Roads were upgraded to traffic lights and the Frankston-Dandenong Road. A new bridge over Peninsula Link has been constructed and new safety features implemented along the whole project including the construction of centre medians and installation of safety barriers.

Leakes Road

Sub-Heading to project name: Western Roads Upgrade Project
Business Units: Infrastructure
Location: Truganina, Victoria
Client: WBHO Infrastructure Pty Ltd
Industry Sector: Transport
Others Solution: Major Road Projects, Utilities, Plant and Equipment, Surveying, Traffic Management
Key Achievement :
- Traffic management. Winslow worked with in-house company, Trafman Solutions, to develop and implement complex traffic controls that enabled construction under live traffic on a very busy arterial route.
- Timing of winter works. Winslow managed the placement of 50,000 tonnes of asphalt during the winter months. Safety management - to address the challenges of working in proximity to high voltage powerlines and piling rigs, Winslow implemented overhead gantries for protection of overhead services and incorporated electromagnetic lockout systems on piling rigs and booms used in the works.
- Utilities management. improved excavation permit processes and use of 3D imaging technology streamlined delivery of service protection and relocation works. Winslow also managed complex relocation of APA’s high-pressured gas main through the adjacent Federation Trail with 18 months of pre-work and SMS risk workshops leading to success.

As part of the Western Roads Upgrade, this major road project involved the duplication of Leakes Road between Derrimut and Fitzgerald Roads making it easier for residents to get to work, shops and community services in Truganina.

New lanes were added over 8km in each direction along the busy arterial road that carries 22,000 vehicles per day. Works on major structures included duplication and widening of the existing two-span bridge, construction of a nine-span dual super-T beam overpass and upgrades to 18 intersections to create a more reliable and safer east-west route for locals.

Sunbury Road Upgrade

Business Units: Infrastructure
Location: Sunbury, Victoria
Client: Major Road Projects Victoria (MRPV)
Industry Sector: Transport, Civil Infrastructure
Others Solution: Major Road Projects, Utilities, Plant and Equipment, Surveying, Traffic Management
Key Achievement :
Environmental and sustainability management: The team implemented a range of key initiatives, trialed Victorian first innovations and received an “Excellent” rating from the Infrastructure Sustainability Council during the first “design” round.

Community and Stakeholder Engagement: The team collaborated with the community to construct a 40m long mural on the Jacksons Creek retaining wall. A whole range of community groups and stakeholders were involved in the process of picking the local artist and deciding the theme of the mural.

Social Procurement: Over the lifetime of the project, the project spent approximately $5.5 million on Indigenous sub-contractors or suppliers and almost $2.3 million on social enterprise sub-contractors or suppliers.

The Sunbury Road Upgrade project involved adding extra lanes between Powlett Street and Bulla-Diggers Rest/Loemans Road. New traffic lights now replace the roundabouts at Francis Boulevard and Lancefield Road and traffic lights have been installed at the Sunbury Eco-hub. A new bridge over Jacksons Creek and new walking and cycling paths have also been constructed, improving safety and reliability for the community.

Winslow Infrastructure appointed contractor for Coomera Connector

In an exciting announcement, Winslow Infrastructure in Queensland has been contracted by the Department of Transport and Main Roads (TMR) for the Coomera Connector Stage 1 – Early Works – Nerang River to Nerang-Broadbeach Road.

The 16km Coomera Connector (Stage 1) will be delivered in three construction packages to relieve pressure on the M1 by providing an alternative route for local traffic and additional crossings of the Coomera and Nerang rivers and provide more transport options on the northern Gold Coast.

The early works program will make the site construction-ready with vegetation clearing, relocation of service utilities, bulk earthworks, and preloading activities to be undertaken to support the next stage of construction, where new embankment and excess material will be placed on the existing ground for approximately six months to consolidate and increase the bearing capacity of the underlying soft soils.

Once settled, the excess embankment will be removed and ready for this stage of the Coomera Connector motorway.

The connector will improve and provide more reliable travel times between Brisbane and the Gold Coast by reducing the number of local trips on the M1 and increase safety.

The Australian and Queensland governments have committed a total of $3.026 billion to the project.

It is an environmentally sensitive area requiring a Koala Management Plan to ensure that koalas are appropriately protected during construction and operation.

“Winslow is delighted with the announcement which is another huge step in Winslow Infrastructure’s growth in Queensland and a great opportunity to further expand our delivery portfolio with Dept. Transport and Main Roads,” said Winslow Queensland Regional Manager Anthony Rosario.

The early works are expected to begin in July 2024 and be completed by late 2025.
