Investigation and remedial action for tree root damage to property

Frilford Heath Golf Club, Abingdon OX13 5NW

"Investigation and remedial action for tree root damage to property" is an extended version of the talk "Is that tree too close...?" given by Dr Giles Biddle at the Building Surveyors' Oxford Briefing 2017 conference.  In this evening talk, there will be more time to explore avenues of interest and respond to questions.

Dr Giles Biddle was a Registered Consultant of the Arboricultural Association until his retirement, and is an Honorary Fellow, Institute of Chartered Foresters.  He was awarded an OBE for services to arboriculture and the environment in the New Year's Honours 2000.

Tree Root Damage to BuildingsHe is the leading expert on tree-related subsidence damage, and the author of the definitive book on the subject, Tree Root Damage to Buildings.

The majority of his work for over 40 years has concentrated on all aspects of tree root damage.  In 1978 he was commissioned by Milton Keynes Development Corporation to start the research which is described in Volume 2 of Tree Root Damage to Buildings. The National House-Building Council (NHBC) commissioned an extension to the research in 1984, with this leading to his appointment as consultant to NHBC for the 1985 revision of Practice Note 3 "Building near Trees".  He provided all the technical input, both for this edition and its subsequent revision as NHBC Standards, Chapter 4.2. These have become the industry standards for foundation design near trees.

The research has also provided the basis for reappraising methods of site investigation and developing techniques which are practical and relevant to decisions on remedial action and the prevention of subsidence damage, with emphasis on the arboricultural options which are available.  These techniques and concepts, which have evolved and been honed during about 3,000 detailed investigations, are presented in Volume 1 of Tree Root Damage to Buildings.  The investigations have been for a wide variety of clients, particularly insurers, loss adjusters, solicitors and local authorities throughout the country.

He was previously chairman of the British Standards committee for the extensive 1991 revision of BS 5837 'Trees in relation to Construction' which provides the definitive guidance for building near trees. He was also on the panel for the 2005 revision of this Standard. He was one of the principal authors of the NJUG publication No. 10 on utility services near trees.
