Earthworks: Theory to Practice - Design and Construction

Case studies are used to show how theory is applied in practice. In the design and construction process, various models are used – geotechnical, laboratory, analytical, delivery, and economic models as the project is developed from planning to construction. This book explores the use and limitations of these earthwork models to be understood and appropriately applied.

This book evolved from an earthworks course to practicing engineers over a 10-year period. Theory alone is not enough. Experience alone without relating back to theory can sometimes be misleading if transferred without understanding the fundamentals. The book benefited from the experiences of those many practicing engineers and the author’s experience in multi-disciplinary consulting companies as well as specialist geotechnical companies and government departments.

The basics of soil, rock and compaction mechanics as applied to field conditions are covered. Material typically not covered in other textbooks, include the applications and limitations of associated "standard" laboratory and field testing. Specific chapters are dedicated to excavation, subgrade and expansive clay assessment and treatment. Useful design practices as well as the development and application of specifications is covered. A specification, test or design in one climatic condition or geology may not apply in another.

Burt G. Look has 40 years professional engineering experience with his early years in structural and civil works before specialising in geotechnics. He obtained his postgraduate degree from Imperial College, London in soil mechanics and engineering seismology. His PhD was obtained from The University of Queensland through part time studies, while working at Queensland Main Roads.

He has been a consulting geotechnical engineer for most of his career, and most recently a senior principal and director at FSG – Geotechnics and Foundations. He was previously the Global Geotechnical Practice Leader in SKM (now Jacobs), and the Global Geotechnical Group leader at Aurecon. Burt is the 2014 Queensland Professional Engineer of the year and the Australian Geomechanics Society (AGS) Practitioner 2018 – a biennial award. He was awarded the Medal of the Order of Australia (OAM) in 2020.

He is widely recognised in the areas of earthworks, expansive clays, landslides, risk assessment and site characterisation. He has been a technical advisor and expert witness in these areas. Burt developed and presented "Earthworks"- a course for practicing engineers, and over 1,000 professionals attended to date. Burt has published three geotechnical engineering books and over 90 technical publications focused on industry practice developments within Australia.
