ADG identified:

• There was no architectural finishes information provided as part of the data transfer and followed up with Translink to avoid reinventing the wheel
• The building class was 10A and therefore meant that the requirements that we need to meet were significantly less onerous than Translink thought / had used previously.
• The requirement of an Environmental Scoping Report, which then identified significant issues that needed to be closed out. Early identification meant that design program milestones were still met.
• Through collaboration with Energex that the existing site power supply was insufficient to power the facility but came up with an alternative power supply arrangement resulting in significant cost savings for the client.
• The 50mm step down between the lunchroom and the AC/Comms Room was not required resulting in time and cost savings due to enabling a significantly simpler construction methodology to be adopted.
• If buses were to circumnavigate the roundabout, this opened up the full length of the available area hence enabling more bus parking to be realised.
• That stormwater treatment (quality) is not providing any real benefit, and therefore again collaborated with the client to agree to significantly scale back on this item in the design to save the client significant cost.
• The existing asphalt pavement depth, integrity and extents are in accordance with layout requirements and therefore with a minimal amount of corrective work, further cost savings were available to which Translink agreed.
• Alternative solutions although the existing roundabout pavement and stormwater protection elements are piled, saving the client a significant amount of money.
• A number of ambiguities/unknown in the as-constructed electrical information provided for the design, and therefore initiated a series of site visits with the relevant organisation representatives to close these out, ensuring that the design is done right to avoid potential delays to the Energex approvals process.

With no existing water and sewer property connections in place, ADG came up with innovative low cost solutions that were approved by the relevant authority to enable the connections to occur. Understanding the amount and concentration of existing services in the road and the road verge on Bowen Bridge Road based on the as constructed information, ADG were able to collaborate with the client to agree on the critical importance and potential extents of the potholing required to provide robust design documentation.

ADG were able to accommodate the hydrologic conditions imposed by TMR into the bus driver facility design with minimal changes. As the building was now required to impose little or no impedance to flow and change to existing adjacent afflux levels during flood events, while catering for debris loading, ADG changed the structural support system from blockwork to a minimum number of 100 x 100 SHS’s with cross bracing on screw pile foundations. To enable to make this happen, ADG also changed the above floor level cladding to a lightweight alternative to minimise dead loads imposed on the structure, but still meeting the maintenance minimisation, hardwearing criteria outlined by the client.

The ADG team also introduced timber poles and overhead catenary into the design for the bus layover lighting and underground electrical services susceptible to impacts of tidal/flood water inundation to negate corrosion and maintenance of hot dipped galvanised iron poles and associated infrastructure. Similarly, the ADG team came up with the idea of extending the existing CCTV network on the adjacent overpass structure for the same reasons.
