Professional Experience

 

February 1993 – April 1994 Civil Design Engineer, SASOL Technology, South Africa

Employed by SASOL, a large petrochemical company in South Africa, as a civil design engineer. Spent an initial 7 months in their design offices, involved in designs across a broad spectrum of civil and structural engineering.

Design work included structural steel building design, retaining walls, water-retaining structures, pipeline reticulation schemes, pipeline supports, chemical-spill channels, dam stability checks, chimney stability checks, and the design and construction of a large (30m by 13m by 3m high) reinforced concrete support structure for rotating machinery. This particular structure was also designed, in parallel, in structural steel but the concrete solution was chosen in the end due to fire-proofing costs.

Promoted to team-leader of concrete construction on a £90m chemical plant erection project. Involved in fast-track design of the civils work for this project, and spent the final 8 months of my employment with SASOL on site as Resident Engineer for all Concreting Works. In addition to my main role as technical support on site, I oversaw all payments, scheduling, claims and interdisciplinary site control. The project was completed on time and under budget.

 

April 1994 – Present Intermittent Consultancy Services to Clients

On an intermittent, ongoing basis I carry out plastic strength assessments of existing concrete bridges in the United Kingdom. Clients have included WS Atkins, Acer Consultants, Norfolk County Council and Strathclyde Regional Council, amongst others.

 

Professional Associations

 

Application for membership of the Institution of Structural Engineers was submitted during June 2000, via the submitted-papers Research Route. The outcome is awaited.

 

Research Experience Summary

 

The bulk of my research has been aimed at the behaviour of concrete structures, reinforced with conventional steel and/or fibre-reinforced plastics (FRPs).

 

Present Research Students and Staff under my Direction

 

October 1998 – Present Man Cho CHOI, registered for Ph.D.

Man Choi is presently in the second year of his Ph.D. He is studying the behaviour of primary anchorage zones for FRP-prestressed concrete structures. This localised zone relies heavily on the bond and geometry of the FRP reinforcement. His work involves experimental, analytical and numerical modelling of the problem.

Funded by the University of Bath.

 

October 1998 – Present Paul Whitehead, registered for Ph.D.

Paul Whitehead is presently in the second year of his Ph.D. He is studying the behaviour in shear of FRP-prestressed concrete structures. In particular, by using novel reinforcement layouts, he is attempting to use FRPs efficiently as concrete reinforcement. His work involves experimental, analytical and numerical modelling of the problem.

Funded by an EPSRC Studentship

 

June 2000 – Present Luke Gale, registered for M.Phil./Ph.D.

Luke Gale has recently embarked on his Ph.D, registered in the first instance for an M.Phil. He is studying the behaviour of secondary anchorage zones for FRP-prestressed concrete structures. This zone traditionally uses excessively high quantities of reinforcement. His work will involve experimental, analytical and numerical modelling of the problem.

Funded by an EPSRC Studentship

 

From August 2000 Post-Doctoral Research Officer

A Post-Doctoral Research Officer, looking at the structural integrity of existing concrete bridges which contain inadequately anchored reinforcement, will be appointed during June 2000 and will start during August 2000. This project represents an important area of research for the bridge-assessment fraternity, who desperately require guidance on anchorage requirements. The research will involve experimental and analytical modelling of the problem.

Funded by the EPSRC
