Three test bores were put down on a triangular pattern over the site. Bore No. 1 was stopped in hard gravel at a depth of 26 feet and Bores No. 2 and 3 were each carried to a depth of 30 feet. A sequence of firm to very stiff silty and sandy clays, with some grit and gravel, was encountered. All bores terminated in gravelly material. Whilst there is a general similarity in the materials encountered in all bores, there are marked differences in the degree of consolidation of the various strata from bore to bore, as indicated by the variations in the penetration figures. The data available are not adequate for a proper assessment of the optimum depth and bearing capacity for the press foundations. Therefore 5 additional bores, each 20 feet deep, are recommended between Bores Nos. 1 and 2. Five undisturbed samples should be taken from each bore and tested in a soil mechanics laboratory. For the deep trench running beneath the line of presses no problems are anticipated. Despite a very wet winter no free water was encountered in the bores, excepting in the top 18”. Materials encountered are mainly finely sandy and very silty clays, ranging from firm to very stiff, which should stand well on excavation, without significant shrinkage or cracking.
