A site investigation has been carried out for Public Buildings Department for a two storey Primary School at Mansfield Park. The proposed design is for a concrete building with load bearing walls, seated everywhere upon driven piles (Frankipiles) with point loadings of 30 tons, 50 tons and 80 tons, respectively. The investigation was requested in a letter to the Director of Mines on 28th August 1964. Two percussion drill holes were drilled at the site, Hole 1 penetrating to 63 feet and Hole 2 to 100 feet. Open tube samples were taken throughout both holes and sealed tube sampling also was undertaken in Hole 2 at approximately five feet intervals. Standard Penetration Tests were made at selected depths in Hole 2. The holes have been logged on a scale of 1 inch to 10 feet and the materials encountered have been classified according to the Unified Soils Classification System. This report sets out the results of the drilling and briefly discusses the foundation characteristics of the soils at the proposed site.
