CONSTRUCTION GEOMETRY Brian Walmsley. 2d ed. Scarborough (ON), Centennial College Press, c1981. Distributed by Centennial College Press, Box 631, Station A, Scarborough, ON, M1K 5E9. 170pp, paper, $9.95. ISBN ISBN 0-919852-19-X. Grades 12 and up. Reviewed by P. F. Chernoff. Volume 12 Number 1 1984 January Construction Geometry is intended to help trades people develop an analytical and logical approach to layout problems. It is meant to be used in school courses and as a job reference manual in the building industry. The book starts out with basic high school construction geometry, providing diagrams, construction directions, and exercises. It then applies this information to designing the following: stairs and railings, arches, tunnels and vaults, roofs, and laying out surface shapes. Construction Geometry ends with six pages of conversion factors between metric and imperial measures often used in the building trades. It has many drawings and a dozen black-and-white photographs illustrating some examples of the applied structures. The applied geometry portion of the book is short and brief, and there is a rather large step between the geometry and its application. Walmsley assumes that the student has an understanding of the basic principles of stair construction, for example. Construction Geometry should be considered as additional reference material rather than as a comprehensive text. P. F. Chernoff, Thorn C. I., Regina, SK.
