Simplify the estimating process with the latest data, materials, and practices Electrical Estimating Methods, Fourth Edition is a comprehensive guide to estimating electrical costs, with data provided by leading construction database RS Means. The book covers the materials and processes encountered by the modern contractor, and provides all the information professionals need to make the most precise estimate. The fourth edition has been updated to reflect the changing materials, techniques, and practices in the field, and provides the most recent Means cost data available. The complexity of electrical systems can make accurate estimation difficult, but this guide contains all the necessary information in one place. An electrical estimate represents the total cost for materials, labor, overhead and profit, but accuracy is virtually impossible without a basic knowledge of the field, and real-world experience in the type of work required. Inaccurate estimates lead to problems with customer satisfaction, which often create payment issues. A thorough, complete, and accurate estimate is in the best interest of all parties involved in the work. Electrical Estimating Methods provides more than just data. Detailed discussions about the work itself help highlight factors that may escape notice, and access to the latest cost data helps tie everything together. Features include: Discussion of current equipment, materials, and processes Means data for both residential and commercial projects Case studies that illustrate best practices Online access to the latest Means data for fast access on the job The book discusses specific situations as well as general practices, and provides comprehensive guidance to the creation of a true, current, estimation of costs. For electrical contractors and estimators, Electrical Estimating Methods contains must-have content that simplifies the estimating process.

This text provides a comprehensive look at how to estimate electrical wiring for residential and commercial buildings with extensive discussion of manual vs. computer-assisted estimating. Each chapter focuses on a specific component such as the estimating process, labor units, estimate recap, bid processing and bid analysis, as well as contracts and proposals. Case studies, blueprints, a price and labor unit catalog and typical estimating forms provide real-world examples. Learning is reinforced through chapter objectives, summaries and review questions.

With this authoritative, easy-to-follow guide, you can design and specify electrical systems for virtually any commercial building easily, efficiently, and accurately. You'll be able to submit lower bids, foster greater client satisfaction, and encounter fewer problems during construction. Electrical Design Guide for Commercial Buildings shows you step by step how to organize, layout and circuit, and complete the design of electrical power and telephone/communications systems for commercial and industrial buildings. Whether pro or novice, you'll find the key to better, faster, and cheaper electrical design for commercial buildings inside this book.
