Position in company:
Graduated from imperial college, University of London in 1971 with an honours degree in Civil engineering. Spent a year out working with Taylor Woodrow on an irrigation project in Southern Romania, employed as a section engineer on the construction of distribution canals. In 1971 joined a London property company as an in-house structural engineer. Administered and designed a number of residential and commercial developments in the ensuing two years, working principally as a project manager.
Joined MMP in Cambridge as structural consultant on a variety of international civil engineering projects. These were principally for the World Bank, the FAO and the United Nations. Most of the projects were related to agriculture and water supply projects in the third world. My role was within the design group of the civil engineering department. I remained with the practice for six years, during which time I worked on projects throughout the third world and gained a thorough understanding of the problems in these areas. Became involved with the problems of montmorillonite soils of Africa and the associated heave and subsidence problems.
In 1978 I set up a private consultancy practice in structural engineering. Through the process of evolution, this grew into my current practice, Packman Lucas.
At present the practice comprises fourteen technical staff and three non-technical. The workload is centred on commercial and residential developments in Central London. Contract values range from £0.5 million to £30 million. In 1996 was granted a patent for a process involving the controlled rehydration of clay soils as an alternative to mechanical interference with foundations.

Position in Company
After completing my PhD investigating how structures respond to movement of the soil beneath the foundations, I spent five years in Western Australia dealing with soil and rock mechanics problems of a widely varying nature.
Upon returning to the UK in 1990, I worked as a loss adjuster specialising in the investigation of subsidence/heave/landslip claims and liability claims, particularly relating to effects of tree roots. In 1996 I set up Subsidence Management Ltd and am responsible for the day-to-day running of all our offices, which cover most of England and Wales south of Manchester, but continue to be actively involved in the field.
In addition to maintaining my own case load, I am continuing to progress the development of soil rehydration as an alternative to underpinning and as a tool to potentially reduce the time span required to finalise subsidence claims caused by clay shrinkage. I have been an accredited Expert Witness of the Law society in matters relating to subsidence, heave, Landslip and tree root nuisance since 2001.
