A definitive how-to book for every practitoner of sports turf -- from football to baseball to soccer and everything in between. Sports Fields covers every important aspect of planning, design, construction, and turfgrass maintenance with hundreds of illustrations and step-by-step procedures to help you get the job done right -- first time, every time. No other book provides such intricate detail, combined with easy-to-understand guidance.
The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
This is the classic, comprehensive manual on how to build a footpath to withstand the beating of 8 million boots a year (some hitting the ground 5 million times), to rest lightly on the land, to preserve the natural resources around it, and to allow a true backcountry experience-all at the same time. It is addressed to those who work on the Appalachian Trail-4,500 volunteers putting in a total of more than 185,000 hours a year-but is used by veteran and novice trail-builders around the world because of the success of the Appalachian Trail system. Illustrated with more than 50 photographs and 100 explanatory drawings, this manual includes design and construction specifications and lists of tools and U.S. suppliers.
Innovative Bridge Design Handbook: Construction, Rehabilitation, and Maintenance, Second Edition, brings together the essentials of bridge engineering across design, assessment, research and construction. Written by an international group of experts, each chapter is divided into two parts: the first covers design issues, while the second presents current research into the innovative design approaches used across the world. This new edition includes new topics such as foot bridges, new materials in bridge engineering and soil-foundation structure interaction. All chapters have been updated to include the latest concepts in design, construction, and maintenance to reduce project cost, increase structural safety, and maximize durability. Code and standard references have been updated. - Completely revised and updated with the latest in bridge engineering and design - Provides detailed design procedures for specific bridges with solved examples - Presents structural analysis including numerical methods (FEM), dynamics, risk and reliability, and innovative structural typologies
Building one's own house is a dream entertained by every person, whatever be its size or level of amenities. This book aims to serve as a guide to all those who wish to undertake house construction, in relation to architectural and structural design, selection of the right set of materials for construction, methods of construction and carrying out maintenance as a routine periodic activity. In short, the book tells the reader how much of engineering goes into every aspect of house construction which they ought to know, rather than choosing to remain blissfully ignorant of it. The topics covered include, among others, municipal requirements, engineering design and drawing, types of soils and foundations, cement, steel, timber, ceramic products, production of sound concrete, damp-proofing and water-proofing, painting, plumbing, electrical connections, earthquake resistance and retrofitting, concrete repair chemicals, corrosion inhibition in steel, repair of leakages, anti-termite treatment, rain water harvesting, Vasthu, bar chart, cost estimating, etc. The book also meets the needs of diploma and degree students in civil engineering. It also serves as a source providing the necessary background material for postgraduate students of construction management (as part of the management stream) who may not have the necessary background in civil engineering.
