The Leading Guide To Site Design And Engineering Revised And Updated Site Engineering for Landscape Architects is the top choice for site engineering, planning, and construction courses as well as for practitioners in the field, with easy-to-understand coverage of the principles and techniques of basic site engineering for grading, drainage, earthwork, and road alignment. The Sixth Edition has been revised to address the latest developments in landscape architecture while retaining an accessible approach to complex concepts. The book offers an introduction to landform and the language of its design, and explores the site engineering concepts essential to practicing landscape architecture today from interpreting landform and contour lines, to designing horizontal and vertical road alignments, to construction sequencing, to designing and sizing storm water management systems. Integrating design with construction and implementation processes, the authors enable readers to gain a progressive understanding of the material. This edition contains completely revised information on storm water management and green infrastructure, as well as many new and updated case studies. It also includes updated coverage of storm water management systems design, runoff calculations, and natural resource conservation. Graphics throughout the book have been revised to bring a consistent, clean approach to the illustrations. Perfect for use as a study guide for the most difficult section of the Landscape Architect Registration Exam (LARE) or as a handy professional reference, Site Engineering for Landscape Architects, Sixth Edition gives readers a strong foundation in site development that is environmentally sensitive and intellectually stimulating.
Excerpt from The Transition Spiral: And Its Introduction to Railway Curves With Field Exercises in Construction and Alignment The aim of this handbook is to afford concise and complete demonstration of the introduction of transition curves, or spirals, in the various argument problems that accrue in connection with the construction or improvement of railway curves. Now the extent to which such problems can be satisfactorily essayed depends upon the mathematical development of the form of transition adopted, and the facility with which this development admits utilisation in the field - the effective compromise of mathematical truth with practical precision. Hence, besides fulfilling its objective function, the ideal transition curve must be easy and flexible in construction; a curve with simple, definite relations to main curves and straights; and, above all, one which can be introduced without the aid of special tables, such as hamper the construction of American tabular spirals. The curve most readily amenable to these requirements is to be found in the clothoid = m the spiral advanced and investigated in this connection by Mr. James Glover, M.A., A.M.I.C.E., in a paper read to the Institution of Civil Engineers.
