Director & Principal Electrical Engineer

Over 20 years of experience in the design of 11-220kV networks consisting of both overhead and underground construction.
Helped develop Network Standards for Line Design for Ausgrid.
Trained and supported new line designers throughout Ausgrid.
Grant was on the committee for the original development of AS/NZS 7000 and HB331.
Intimately familiar with line design software such as TL Pro, Neara, Poles & Wires, and PLS CADD.
Has successfully deployed Neara network models for a number of utilities in AU/NZ and provides ongoing support for many of Neara's customers locally and internationally.
Has trained over 200 line designers across Australia and New Zealand.
Company lead on LiDAR processing, geospatial data implementation, and data management for use in design and vegetation management in Ausgrid. Leading to development of Ausgrid’s policies on bushfire risk mitigation on long spans.
A career highlight was being the project lead on a custom system to measure the line blowout on a range of spans with different vegetation shielding to prove that vegetation surrounding powerlines reduces their movement, during high winds, in an approximate linear relationship. This work now forms recommendations within HB 331.

Managing Director & Principal Structural Engineer

Nathan has had a wide range of experience in the consulting sector since 2000 and specialising in the utility sector since 2006.
He has worked on many structural design projects involving 3D finite element modeling, first principles design, product development, forensic assessment, corrosion assessment and remediation design, and numerous testing projects.
Nathan has hands-on tested more than 1200 full-size poles of various materials. He advises standards committees on foundation and timber pole design, and on pole test requirements.
Nathan is especially interested in the long-term performance of all utility poles, and in the relationship between design and asset management. He was the convenor for the CIGRE WG2.67 on wood poles, leading a team of international experts.
He is well-studied in the field of pole foundation design and performance and wrote the revised foundation calculator for Ausgrid and the P-Y calculations and associated training material for Latpole.
Nathan also has specialist knowledge in the field of Polyurea, insulating coatings, and other advanced elastomeric coatings.

David has over 20 years experience in the electrical industry.
He worked in CitiPower/Powercor for 17 years in the design team before joining CoEng
He has performed design works of many types from network augmentation to maintenance programs as well as commercial works for companies such as NBNCo and other utilities around Australia.
David has specialised in setting up systems and providing first principles design expertise, specialising in setting up systems such as LiDAR & digital twin (Neara), GIS, 3D design tools, AutoCAD & Vault (Autodesk drawing and document management tools), engineering/design field mobility solutions, developing system integration requirements and standards/work practice development & training.
David has a long-proven track record of turning concepts and ideas into deliverables that people can easily execute.
Davids’s experience and general passion for first principles design of powerlines means that he has assisted with development of design standards, asset management policies, vegetation clearance assessments, remote inspection among others.
David is finishing his Civil Engineering bachelor’s degree through RMIT to further increase his understanding of structural elements and materials used to build public infrastructure.
