Our People

Tim Cartledge

Lead Geotechnical Engineer – CPEng, RPEQ

Tim has multi-disciplinary experience in civil and mining geotechnics, and mine engineering throughout Eastern Australia and Southeast Asia. He has experience in both industry and consulting roles delivering operational support, studies, technical reviews and audits, operational improvement and open cut mine design.

Tim has provided operational mine planning and geotechnical advice for world class deposits including Mount Isa and McArthur River Mines, as well as small scale, selective mining operations. He has also led mining studies in Iron Ore and Coal, as well as provide support to Coal, Oil Shale and Base Metals operations.

Tim has worked on and project managed geotechnically and commercially complex, large civil projects in residential and mining environments, consistently delivering positive outcomes for all stakeholders involved.

Tim’s breadth of experience has seen him develop a proven track record of delivering practical and economical solutions. This has been achieved through buy-in to the projects and working with his clients to ensure the best project outcomes.


Tom Lynch

Senior Geotechnical Engineer – NPER, RPEQ

Tom has experience planning, budgeted, supervising, and managing geotechnical site investigations for projects ranging from small residential and commercial developments through to large industrial, infrastructure, and resource sector operations. He also has practical and hands-on experience through undertaking geotechnical analyses and design of tailings structures through to construction oversight on commercially and technically complex large mining and oil and gas projects.

Tom has worked on a number of high profile projects across Eastern Australia, regularly delivering on rigorous safety requirements and project deadlines. He consistently exceeds client expectations on ensuring they understand and manage their risk while delivering quality outcomes on time and budget.

Graeme Boyd

Principal Engineering Geologist

Forty years in civil, mining and allied industries providing engineering geological, soil mechanics, rock mechanics and groundwater hydrology expertise in feasibility studies, pre-development studies and project operation investigations.

Project management (technical) of multi-disciplinary study of 4.5Mtpa brown coal mine plus site power station development, involving reserve analysis and reliability estimates, geotechnical and hydrogeological design, coal quality combustion assessment, environmental factor assessment, minesite and community infrastructure and economic evaluation of both mine and power station costs.

Thirty years in open strip mine design, prospect evaluation (geotechnical factors), research investigations in pit slope stability and research and assessment programs for second generation pre-stripping techniques, principally dragline and bucket-wheel excavators.  Research and problem solving experience in coal handling and large scale production blasting.

Strata control and support requirements planning for proposed longwall mining operations, and for multi-level unit mining operations.  Primary and secondary pillar recovery technique analysis in unit mining operations.  Analysis of ground support requirements, subsidence profiling and surface damage predictions by numerical simulation.  Analysis and prediction of water inrush potential to longwall mining operations using numerical simulation techniques. Development of analytical techniques for the evaluation of ground condition and subsidence of voids during and following UCG panel development.

Participation in foundation research and development of highwall mining techniques applied to open strip coal mines.  Also owners’ representative for key technology transfer (Sirovision automatic joint recognition and universal dig and dump dragline technology).


Fernando Vieira

Principal Geotechnical / Rock Mechanics Engineer -

Over a period of 29 years, Fernando worked on surface and underground mines sites, on operations technical branches and Corporate, on mining technology innovation programs, and technical-scientific R&D Centres for mining; his expert-level background encompassing Mining Engineering; Rock Mechanics, Mine Geotechnical Engineering, and Mining Technology; addressing gold, copper, coal, platinum, iron-ore and base-metal mining environments around the world;

His professional experience and expertise are varied, and sound. More recently, at Rio Tinto T&I, Fernando directed the specialist geomechanics functions for delivering Underground Hard Rock Mechanical Excavation projects, the tunnel boring systems for developing accesses in block caving mines; he managed the machine-boring data productivity teams assigned to the TBS trial sites. For Anglo American, he managed mine production activities on deep, high-stress, seismically active underground mines in South Africa. And for AngloGold Ashanti he led multi-disciplinary and multi-country (multi-culture) mine-technical teams, including geotechnical engineering, rock mechanics, and feasibility study teams in mining regions of Brazil, Argentina, and Colombia, each of which operated different methods of mining. He coordinated the delivery of various technology innovation projects and led teams in Mining Collaborative Research Centres. Earlier, Fernando headed for the Division of Mining Technology, at the Council for Scientific & Industrial Research, the programs of Minerals’ Extraction Optimisation; FutureMine; Mine Seismicity Risk & Mine Design; and the program of DeepMine, among the most industry-impactful. 

He has been offering expert advice in geomechanics, rock mechanics, geotechnical engineering, and mine technology innovation deployments on an ad hoc basis, as being an Expert Advisor to the Australian Department of Industry Innovation and Science on matters related to geo-technology applied to mining.

Fernando is currently a Program Director at Mining3 where he leads expert teams on a wide-ranging portfolio of projects to develop game-change technology for productivity and safety improvements to mining. He is Program Coordinator, also, of the technology area “Separate” at the CRC ORE, champion work to developing grade engineering-enabling technology for early coarse separation (in pit) of ore and waste material, in advance of mineral processing, markedly rising the net value of mining.

Fernando holds an MSc in Mining Engineering, a PhD in Mining Rock Mechanics, and an MBA in International Business Management. His industry qualifications include a Mine Manager’s Certificate of Competency for Metalliferous Mines, and a Chamber of Mines Certificate in Rock Mechanics. He is fluent in English, Portuguese, and Spanish. He is a permanent resident of Australia and lives in Brisbane


Alison McQuillan

Lead Geotechnical Engineer – CPEng, RPEQ

Alison has been working as a geologist and geotechnical engineer in Australia, South Africa and Canada.
