Contract works includes construction of a new drivers facility building suspended on Bondek structural slab supported on structural steel and piled foundation,  pavement construction for the bus layover area, construction of a new watermain and sewer via tunnel boring, electrical works, landscaping, signage and linemarking.
With vibration management being a key risk for the project, McIlwain developed a cost saving and innovative design alternative during the tendering period in lieu of the original precast driven pile design. The alternative design consisted of a D&C bored pier and micro pile for the pile solution. The alternative design will alleviate site access issues, vibration concerns and reduced traffic management.
Contract works also include an external 795mm deep pavement using fibrecrete concrete with high dosage of fibres (75kg per cubic meter). The fibrecrete pavement is supported by various other pavement types such as Lean mix pavement, CTB pavement and granular pavement.
This multidisciplinary project is located within one of Brisbane’s busiest road networks. All bus movements will be maintained throughout construction to ensure the public transport network is maintained. Live connections for water and sewer will be carried out at night due to works being situated within live traffic lanes on the busy Bowen Bridge Road corridor.
The site is listed on the environmental management register as the soil contains high levels of lead and asbestos which requires advanced coordination during disposal stages. Additionally works will be conducted next to the Engoggera Creek which will require significant environmental management solutions to ensure water quality and the adjacent mangroves are protected.
