Bridge Foundations-Part II. A Survey of the Attendant Problems in Design (Continued)

A PAPER by the present author under the title of "Modern Constructional Practice in Sewerage and Sewage Disposal” was read before the Institution in 1932, and it may be of interest to illustrate two recent examples of certain of the methods therein described, as applied at Cannock (Staffs.) and Ellesmere Port (Wirral) respectively.

OWING to the publicity that has been to given to the fabrication and erection of the machine-shop at Harmondsworth, the author, observing the rules of the Institution not to submit any but original matter, has been compelled to treat the structure in a general manner as part of an engineering paper. Several papers have been read before the Institution, either in London or in the provinces, and they have dealt sufficiently with the actual depositing of weld metal by the metallic arc process to make redundant any remarks about it in this paper.

The author said that before showing the slides and dealing with the paper in general he wished to repair at least one of his crimes of omission. In dealing with the personnel of the job, unfortunately no reference had been made to Mr. W. K. Wallace, M.Inst.C.E., Chief Engineer of the London Midland & Scottish Railway, who was responsible for the preparation of the whole of the scheme when he was engineer of the Northern Counties Cormmittee. Although he left Belfast before the scheme had actually been put under way, most of the smaller bridges had already been designed and the general layout of the viaducts determined. Although he was not directly associated with the construction of the viaducts, his advice was always available and was frequently taken advantage of.
