The Structural Engineer, Volume 56, Issue 6, 1978
The paper presents a review of current practice in foundation design and construction for low-rise buildings and makes recommendations for improved practice in certain specific areas. Requirements in relation both to Building Regulations and Codes of Practice are discussed and the need, when assessing building performance, for an objective and widely accepted approach to the classification of damage is stressed. The BRE classification is presented in an Appendix. A section is devoted to good site investigation practice and various types of foundation are discussed in relation to ground conditions and construction considerations. Special ground problems are covered including shrinking and swelling clays, frost action, mining subsidence, fill and aggressive ground conditions. M.J. Tomlinson, R. Driscoll and J.B. Burland
Mr. D. E. Roe: The first problem that had to be solved was the erection of the riser pipes within the two columns. Fig 14 of the paper shows the congestion that there was in the columns, and this was made worse when the pipework was installed because of the amount of scaffolding inside the columns. A novel method was devised to overcome the lack of working space and to enable the pipework to be completed as soon as possible after slipforming the columns.
