BG&E has significant expertise and experience in the management of structural and civil infrastructure assets. Our services cover the full range of asset management tasks from the performance of site-based condition assessments to the development of high-level strategies to manage assets to a required service level over a long period of time at the lowest possible cost.

“We deliver solutions that are practical and focus on constructability. Our engineering is about using science to find creative and practical solutions. Always deliver that extra that marks the difference between ordinary to the extraordinary”

Our experienced team have worked on large projects and understand the commercial implications of issues as they arise during construction. We are responsive, offer practical advice, and are diligent in the work we do. We access specialists and testing facilities to be better informed and to ensure projects deliver value to our clients.

BG&E was appointed to John Holland’s tender team for the construct only contract for Green Square Library & Plaza. Our role was to assist in the identification of value engineering opportunities and the use of alternative approaches to reduce the timeframe for delivery of the structure. We participated in the ECI workshops run by the City of Sydney, and enabled a number of cost-saving opportunities to be incorporated into what proved to be the winning tender bid. We then provided ongoing support to John Holland during the construction phase, including the installation of remote monitored strain gauges to measure slab movement, design of temporary works, and assistance in the resolution of construction related issues. The project has been delivered ahead of schedule, with demanding quality requirements maintained during construction.


BG&E were engaged to provide inspection and advisory services to the viaduct section (SVC) and the station construction package (OTS) of the Sydney Metro: Northwest project. BG&E deployed a team comprised of materials and structural engineers, with the necessary technical and project experience to complete the required works in a tight timeframe. The team conducted inspections of 900 precast box girder sections, cast in-situ piers and parapet sections along the length of the viaduct. BG&E also provided assistance in the scheduling of precast element production, in order to assist in the delivery of the station structures.


BG&E are provided services as a concrete specialist on the Phase 2 development of the Oyu Tolgoi gold and copper mine in Mongolia. BG&E is assisting the mine operator in reviewing concrete mixes being utilised more than 1 kilometre underground, and advising on the use of additives in concrete for shotcreting operations. This work involves attendance at the mine site to oversee works, inspect defects as they arise, and audit production equipment used in the mine expansion works.


BG&E was appointed by John Holland to advise on durability requirements to achieve the proposed 160-year design life for the structure, which is directly under the Opera House and is permanently exposed to saline water. We also provided various forms of advice relating to the completion of construction works. Services included developing a framework for ongoing testing and defect identification to be integrated in the asset operation and maintenance plan.
