Dr P. Broughton . (Philips Petroleum .Co.) I would first like to congratulate Dr. Plum on his paper and presentation, explaining the mechanical properties and behaviour that could be achieved using polymer or epoxy materials, in order to repair damaged concrete structures.
The design and construction of the tank assembly workshops and the final form of the berth are described. The project, which was completed in 1991, includes a three-bay workshop building with leading dimensions of 136m length, 64m width, and 35m height to eaves. Other works include alterations to existing buildings, the strengthening of the roadway area between the workshop and the berth, and the development of the berth to include a skidding system and permanent launchways.

The strength and stability of trees The question of how an engineer might respond to a request to assess the prospective danger of a tree to a building with which he is concerned, raised in our issue for 19 November last, has called forth much comment. Sir Alfred Pugsley recalls his own interest in the fascinating topic of the structure of trees: Back in 1988 I contributed to The Structural Engineer (vol. 66, p322) a paper on ‘Limits to size set by trees’. I was mainly concerned with the elastic stability of the trunks as columns, and with an elastic limit to branch extension. But it shows that the limits are way beyond the practical extremes found in nature, which are governed by strength problems under wind forces. Verulam
