Callide Creek Bridge Investigation

Project No: 6992

The BEC team were asked to undertake a forensic investigation of the new Callide Creek Bridge in Biloela. The S40 concrete mix exhibited low compressive strength in the relieving slabs, and low 7-day compressive strengths on the piling mix. The concrete test results came in at 38mpa, just under the Main Road’s required 40mpa, bringing into question the building’s strength and durability.  BEC were called in by the concrete supplier who were faced with the possibility of having to demolish and reconstruct the entire structure free of charge if their concrete was proven to be inadequate.

The BEC Team analysed batch records, compressive strengths test results and NCR findings. BEC’s investigation found that following the concrete pour, the test samples were transported over 500kms in unstable conditions (while curing) to the facility where they were tested, which likely impacted its strength. Following our full analysis, the BEC Team assessed that the concrete on site was sufficient to provide the strength and building life expected, and we provided a letter of support for our client which enabled them to avoid rebuilding at their own expense.

Works Depot Upgrade, McKinlay Shire Council

Project No:6884

BEC was engaged by McKinlay Shire Council in support of a functional review and conceptual planning and documentation for an upgrade to the existing Works Depot.  Council required preliminary Depot Yard master-plan, admin building floor-plan, stores shed floor-plan and costing for funding application purposes.

Our multidisciplinary offering for this project covered a wide range of services. We flew up for a measured site inspection and workshop with key decision makers to ensure our delivery was exactly what council was after. We covered indicative spatial requirements, specific layout preferences, parking demand and traffic flow, and landscaping presences. We also undertook a structural design review of the existing portal frame superstructure with reference to current Australian Standards; preparation of spatial layouts for yard, stores and admin (offering three different options); and preliminary costing.
