Available in a range of AS 5100:2017 performance levels, including ‘Low’ (MASH TL2 | EN1317 N2), ‘Regular’ (MASH TL4 | EN1317 H2) and ‘Medium’ (MASH TL5+ | EN1317 H4b), DOLRE traffic barriers have gained an enviable reputation for their life-saving performance and outstanding versatility along bridges… but they’re not just for bridges!
Indeed, DOLRE low stress barriers, including the purpose-designed TL2 ‘Slimline’ variant, also provide the ideal high-performance traffic safety barrier solution for use along engineered structures including retaining walls and embankments – particularly those with complex site challenges such as poor ground conditions or steep embankments beyond the fence line.
While the use of DOLRE along complex roadside retaining wall and embankment applications is increasingly commonplace across Europe, a recently completed installation in the Sydney harbourside suburb of Rose Bay, marks Australia’s first ‘roadside barrier’ installation of the innovative DOLRE Low Stress Parapet System – and the results are outstanding in more ways than one.
Located in the harbourside suburb of Rose Bay in Sydney’s inner-east, this latest DOLRE barrier installation stretches from the corner of New South Head Road, some 102 metres along the southern edge of Bayview Hill Road.
Together with the steep grade of the roadway (which is clearly evident in the photos) and the generally poor ground conditions in vicinity, one of the biggest challenges with the Rose Bay installation is the angle and height of the embankment on the far side of the barrier. Add to that, the high number of vehicles travelling along Bayview Hill Road (especially during school drop-off and pick-up times) and fact that at the school in question – Sydney’s historic Kambala School – is located on the land at bottom of the steep embankment, and it’s easy to see why safety barrier performance is such a critical consideration for this location.
As well as providing protection for students, staff and visitors to the school, the new DOLRE barrier fence provides critical protection for vehicles turning into and travelling along this extremely steep and extraordinarily busy road.
Designed by infrastructure engineering specialists Turnbull Engineering, the footings for the Bayview Hill Road DOLRE barrier incorporated a series of concrete piles, supporting a reinforced concrete strip footing along the length of the barrier. Preparation of the concrete piles and footings was carried out by specialist contractors in conjunction the team from Woollahra Council. The barrier installation work was carried out by a team from DOLRE’s exclusive Australian distributor, LB Australia Pty Ltd.
