Experience

Before establishing his Consultancy Professor Roberts was Dean of the Faculty of Technology and Director of the Sustainable Technology Research Centre at Kingston University. The Faculty of Technology had around 200 staff and over 3000 students and generated a total income around £25M. The Faculty operated substantially as an autonomous unit of the University and he was responsible for all aspects of its performance. A number of externally funded activities were undertaken and the mission of Kingston University to work closely with industry was strongly supported by the Faculty. Throughout his period as a member of the University Executive he spent around 30% of his time supporting research and representing the UK in the development of European and International Codes and Standards. He established and led the Sustainable Technology Research Centre at Kingston. Representational roles included:

· Council Member and Past President of the International Masonry Society

· Chairman, CEN (European Committee for Standardization) TC125/WG1/TG4 (European Masonry Standard for Autoclaved Aerated Concrete)

· Chairman British Standards Institution Committee B525/6/102

· Chairman, British Standards Institution Committee B519/1(U.K. input to European Masonry Unit Standards)

· Member British Standards Institution Committee B525(U.K. input to the 10 Structural Eurocodes)

· Chairman of the Office of the Deputy Prime Minister, Department of Trade and Industry and Engineering and Physical Sciences Research Council masonry research advisory committee.

· Member Masonry Industry Alliance Management Committee

· Member of the Research Assessment Exercise panel for General Engineering in 2001 and 2007.

· Engineering and Physical Sciences Research Council college member

· Member, Higher Education Founding Council review group for Engineering in London.

· Chairman of the University Investment and Re-structuring fund.

Head of the School of Civil Engineering, (1988-1992)

On the 1st July 1988 he was appointed as Mowlem Professor and Head of the School of Civil Engineering at Kingston. This coincided with a time of great change in Higher Education particularly with respect to the expansion of student numbers and changes in the method of funding. The school had at that time a teaching staff of 18.5, 12 technicians and 3 secretarial staff. The staff needed to be re-motivated after a long period of uncertainty when the future of the school had been in doubt. On taking up the appointment the responsibilities within the school were substantially reorganized. A major review and reorganisation of both the degree and HND schemes was carried out and new schemes implemented. The courses retained full accreditation in a period of difficult recruitment and increasingly stringent accreditation requirements. A new MSc "Management Systems In Construction" was introduced and received support from the High Technology National Training Programme for 1991. A second MSc scheme in "Structural Design" was commenced in September 1992 and both schemes received support from HTNT for the 1992-3 academic year.

Head of Technical Marketing and Standards Department, BCA(1987-1988)

In 1987 he was appointed as Head of the Technical Marketing and Standards Department of the British Cement Association. The Department had a complement of 20 professionally qualified staff and covered the areas of Market Development, Standard Co-ordination, Building and Structures, Civil Engineering and Pavements, and a press office. A full advisory service was provided to industry including the provision of expert help and advice when problems occurred on site.

One of his main duties was responsibility for liaison with product associations, trade associations, building materials producers and the technical press. He was responsible for producing Market Development plans co-ordinating all the Association's work in a given market sector and also establishing Association technical policy in key areas for standards, and specification documents. His responsibilities also involved the briefing and supervision of PR agencies running BCA and joint industry accounts, and the supervision of consultants and contract work carried out at Universities. The Department also organized the form and content of all BCA training events.

Part of his role was to identify areas where the expertise of the Association could be used to maintain or increase the market share held by cement based materials. This was carried out very successfully in the housing sector and he was very heavily involved in developing the competitiveness of concrete in the multi-storey building market. In this work it was necessary not only to be fully aware of the requirements of the client and the factors which influence the professional advice he receives, but also the pressures acting on the different segments of the building industry. His total direct budget responsibility was approximately £0.75M but a key part of the activity was the gearing of this expenditure by the formation of common interest groups to contribute additional support to specific activities.

Manager of the Building Group, C&CA(1983-1986)

In 1983 he became Manager of the Building Group, a multi-disciplinary team comprising Structural Engineers, Civil Engineers and an Architect. The work of this Group included all aspects of Building Design and Construction and involved research, development training, advisory and general trouble shooting (This involved an extensive number of site visits to troubleshoot problems and advise at first hand on technical issues).

The work of the Group included the following projects:

• structural design of reinforced and pre-stressed masonry;

• design of reinforced concrete and reinforced masonry retaining walls;

• simplification of the rules for the structural design of reinforced masonry structures;

• innovation in single-storey "shed" type buildings including tilt-up, masonry diaphragm walls,

double Tee construction and precast concrete frames;

• aspect ratio effects in masonry walls;

• determination of characteristic masonry strengths for the revision of BS 5628

• evaluation of the fire resistance of concrete structures;

• design of precast concrete suspended floors;

• operational studies of the efficiency of house building;

• sound performance of separating walls;

• weathering of concrete buildings;

• evaluation of changes in the Building Regulations and preparation of guidance documents;

He was responsible for all personnel, financial and management aspects of the work including the commercial exploitation of technical developments. Part of his role was to manage projects carried out under contract by professional practices.

Head of Section, C&CA(1974-1983)

As Section Leader from 1974, he was responsible for the work of a group of ten staff. This involved a number of projects including, for example:

• the effect of restraint condition on elements subjected to

thermal movements;

• the optimum quantity and disposition of reinforcement to control cracking;

• construction joints in water retaining structures;

• tensile strain capacity of lightweight concrete;

• design and performance of floors subjected to point loading;

• shear behaviour of reinforced concrete blockwork;

• rain penetration through walling;

• thermal performance of walling;

• external insulation;

• joint systems for precast concrete tunnel segments;

In addition to the formulation, funding and management of research, my role included external liaison with outside organizations.

Senior Research Engineer, C&CA(1972-1974)

Following a review of the available literature, a programme of research was initiated to investigating the structural performance of reinforced concrete masonry. This programme was pursued over a number of years and more than 100 reinforced blockwork elements were instrumented and tested to destruction. In order to investigate the long-term durability of reinforced masonry, an electrical resistance technique was developed which enabled the potential for corrosion to be monitored non-destructively. Five sites were instrumented and these were monitored for a period of ten years.

Research Engineer, C&CA(1969-1972)

As a research engineer responsible for a variety of research projects on behalf of the Cement and Concrete Association.
