A Treatise on Engineering Field-Work: Comprising the Practice of Surveying, Levelling, Laying Out Works, and Other Field Operations (Cambridge Library Collection - Technology) (Volume 2)

In the 1840s, the civil engineer Peter Bruff (1812-1900) designed what was then the largest brick structure in Britain, the 1,000-foot-long Chappel Viaduct in Essex. He went on to become a railway entrepreneur and developer, and was responsible for the creation of the resort town Clacton-on-Sea, where he also designed many of the buildings. In this illustrated guide, first published in 1838 and here reissued in the revised and expanded two-volume second edition of 1840-2, he discusses the theory and practice of surveying (calculating the accurate position of points in the landscape) and levelling (calculating the accurate height of points). Volume 2 covers levelling; Bruff gives a brief overview of the theory, then describes the typical equipment used. By discussing such examples as the levelling of a projected railway route, he explains what information should be recorded, and how to avoid common errors of technique that affect accuracy.
