About

Overview

Andrew McNamara was employed in the civil engineering industry before undertaking PhD research that involved a major study into the influence of new techniques used to reduce ground movements around deep excavations. Upon completion of his PhD he was awarded a post doctoral research fellowship at the Geotechnical Engineering Research Centre to enable him to develop and implement construction process related centrifuge research led by industry. In this role he initiated a number of major projects and was appointed as a Senior Lecturer in 2004.

He was a member of the winning team for the Fleming Award in 2004, awarded for excellence in geotechnical design and construction in recognition of work on the Moorhouse draught relief shaft for Crossrail. In 2005 he was awarded a Diploma of the Henry Adams Award, jointly with Professor RN Taylor, by the Institution of Structural Engineers for a paper on his doctoral work and also a Telford Prize, jointly with Dr PRJ Morrison and Dr TOL Roberts by the Institution of Civil Engineers for a paper on the design and construction of a deep shaft for Crossrail.

He is currently chair of ISSMGE TC104 for Physical Modelling in Geotechnics.

Thesis title: GEOTECHNICAL CENTRIFUGE MODEL TESTING FOR PILE FOUNDATION RE-USE

Role: 1st Supervisor

Further information: The research describes how the existing pile foundations in overconsolidated clay are likely to behave when their loading conditions are changed by unloading caused by demolition and subsequent reloading. This is done with the view to re-use the existing pile foundations for the new redevelopments. An increase in capacity was observed when single piles were subjected to load cycles. The influence of these novel pile groups on the existing pile was dependent on the number, length of the mini-piles in the group and centre to centre spacing between the existing and new pile foundation.
