This paper presents a state-of-the-art review of monitoring the inservice behaviour of structures. Much specialist monitoring has been undertaken in geotechnical and foundation engineering, and this knowledge and expertise is now beginning to be applied to monitoring superstructures. Issues dressed in this paper include reasons for installing a monitoring scheme, in what circumstances and at what stage monitoring is appropriate, and the practical issues of how to proceed in terms of where instrumentation should be situated and what instrumentation and techniques should be used.

The oldest finds of glass (10,000 years BC) were made in Egypt. Since that time glassware, drinking glasses and bottles have been produced from the basic components of quartz sand, soda and limestone. Glass is transparent, resistant to acid chemical agents and has a high density; it is therefore the ideal material for flasks, pipettes and containers in chemical laboratories. Professor Dr Ing. G. Sedlacek, Dr K. Blank and J. Gusgen

Mr P. Veale (G) (J. Murphy) I am intrigued by the trial erection and would like to know who was involved in it. Was it the people who did the erecting on site who actually did the trial erection, was it the fabricators, or were they one and the same? Was it inspected as the trial erection took place, or was it put up and then inspected as a group?
