The author considers the requirements for workmanship in the construction of structural concrete. The concrete mix, batching and placing, the design, construction and striking of formwork are all covered, together with the requirements of curing and cold-weather concreting. The author proposes a svstem of tolerances for construction and gives special consideration to surface finishes for architectural effects. T.N.W. Akroyd

This paper describes a method of analysing a structure consisting of a number of piles embedded at their toes and connected to a rigid mass (such as a bridge pier) at their heads. The piles are treated as straight elastic members having any desired inclination in three dimensions. D.G. Alcock

The Chairman remarked that the paper had referred to a 2-ton crane, the existing 2-ton cranes in the low-level hangar having been taken down, reconditioned and re-erected one bay further out on the cantilever roof. But Fig 6 showed a 5-ton crane on the outer part of the cantilever roof. Was that the crane referred to, or was there another 2-ton crane somewhere? If it was a 5-ton crane that had been moved out, had it been necessary to strengthen the roof structure?
