Nairne shopping centre security upgrade

As a part of the final touches to the construction of the new Nairne shopping centre, IAS has partnered with the Mount Barker Council and the Developer to complete a safe footpath for pedestrians commuting along the Bridge Street and Old Princes Highway intersection. This was finalized by delivering and installing eight EABs in a record two-day timeframe.


EAB installation at the Nairne Shopping Centre

IAS's streamlined installation procedure


By streamlining processes, efficiency and quality of our installation work, using years of industry experience and a highly qualified and well equipped installation team, the project was delivered on time with EABs being effective from the installation date.

  1. Dial before you dig to locate any underground services

  2. Mark out hole centres as per site design

  3. Excavate hole for bollard

  4. Place pre-cast concrete footing into ground

  5. Level footing and install bollard

  6. Tidy up and leave a clean construction area



IAS installation procedure

The use of pre-cast concrete bases alone allowed us to save 7-14 days for project completion. Our highly experienced construction team attended the site in a timely manner and proceeded with work with no major problems or delays. Traffic management was handled with care with only minor disturbances to the local commuters.

Footpath design for pedestrian safety


EABs have been proved over time to be the most effective solution for pedestrian safety. Not only have they endured years of rigorous testing but have stood to the test of time and have saved lives in real world crash situations.





The out of control police car and driver with mental illness incidents on Flinders Street in Melbourne are some of the many examples of EABs saving pedestrian lives. Not only is the EAB effective when hit directly, it is also equally effective when hit at an angle or from any side. That is why it is often referred to as an omnidirectional or multifrontal impact attenuator.


From ground up the EABs are designed to be smooth with no sharp edges or protrusions and don't pose a hazard to pedestrians or cyclists. They have the flexibility to be put in a straight line, around complex curves or scattered around strategically. They are a far better choice in pedestrian areas than guard rails or other hazardous barriers.


It is well known in highway engineering and design that for guardrails the angle of impact is of absolute importance. They are designed to be hit at an angle and never directly. The aim of the transportation engineer is to weigh out the benefits and disadvantages of guardrails so that for most drivers hitting them, the barriers work and work well.

Car hitting a guardrail at 90°

These days it is commonly agreed that guard rails should not be placed at intersections with the possibility of a 90° impact. Moreover they pose a hazard for pedestrians/cyclists and are just plain unaesthetic to be in front of a brand new shopping centre.
