Updated to the 2003 International Building and Residential Codes, the fourth edition of Understanding Construction Drawings continues to highlight a range of real construction projects - from residential dwellings to commercial structures. This enhanced edition takes a detailed approach to reading construction drawings by providing thorough coverage that builds the foundation for a broad understanding of the entire construction process, - beginning with a simple duplex home that focuses readers on the fundamentals of views, lines, basic dimensioning, and symbols. Next, coverage of a multi-level single family home goes into more depth in orienting and cross-referencing drawings. The third section explores multifamily construction and is accompanied by more complex drawings for practice and more advanced interpretations. The final portion of the book introduces readers to elements of commercial construction, including structural steel, masonry, and reinforced concrete. A set of drawings accompanies each building so that readers can apply important skills and gain a "real-world" understanding of construction drawings.
