OUR PEOPLE

Jason Leach

Jason A. Leach, serving as Principal Consultant at Pavement Asset Services, brings over 25 years of profound experience in the fields of geotechnical and pavement engineering. With a Bachelor of Engineering in Civil (Honors) from the University of Adelaide, and as a respected member of the IEAust and the Australian Geomechanics Society, Jason has developed an extensive career marked by significant contributions to various sectors including mining, defence, transport, and local government.

Jason’s expertise encompasses a broad spectrum of geotechnical engineering, from earthworks and in situ and laboratory testing of soils to complex modeling, footing, retaining wall, and pavement design. His comprehensive approach has been instrumental in planning and executing geotechnical investigations, ground characterisation, and design analyses for deep and shallow footings, retaining walls, and pavement design. Jason’s proficiency extends to slope stability assessment, preparing intricate reports, design reviews, and providing ongoing geotechnical advice through the construction phase.

In recent years, Jason has honed his focus on the technical aspects of pavement engineering, delving into the investigation, analysis, design, and performance issues for a wide array of civil, commercial, and industrial road and hardstand projects. His involvement in major road projects and design reviews showcases his ability to provide expert advice throughout the project lifecycle, from planning to construction. Jason’s hands-on experience with various geotechnical failures in slopes, pavements, and structures further solidifies his role as a trusted advisor and problem solver.

With a longstanding history of delivering geotechnical engineering projects through his tenure with Coffey and Wallbridge Gilbert Aztec, Jason has contributed to major projects like Goodwood Springbank Daws Intersection Upgrade and South Road – Torrens to Torrens. His experience covers minor projects as well, including roundabout and intersection upgrades, realignments, extensions, and local and rural council road maintenance and upgrade programs. Notably, his design and implementation expertise for heavy-duty pavements and hardstands, including intermodal and grain handling facilities and industrial pavements, demonstrate his capability to handle complex and demanding engineering challenges.

At Pavement Asset Services, Jason Leach stands as a pillar of technical excellence and seasoned guidance, driving the team towards innovative and robust solutions in geotechnical and pavement engineering. His dedication to providing comprehensive geotechnical and constructability advice ensures that each project not only meets but exceeds the highest standards of quality and safety.
