Architectural Graphic Standards continues to be the go-to guide for construction detailing in most American firms. The book includes thousands of illustrations, from isometric sectional cut-away views to two-dimensional details, which help an architect understand the intricacies of architectural detailing.
The Twelfth Edition follows the overhaul that was made in the Eleventh Edition. The book is organized based on UniFormat, which is systems based - substructure, shell, interiors, services, materials, etc. The new organization will take some getting used to for those used to older versions, but better aligns with how architects work - especially in early stages of design.
Dimensional information on the human body - space needs for sitting, standing, reach distances, etc - is back in the book. Many readers also complained about the previous version lacking information on vehicle sizes, parking layouts, and turning radii, but some of that has made it back into this edition.
While the new layout may confuse some architects who have been using older editions of Architectural Graphic Standards for many years, we think the improvements were needed to address contemporary changes in the way we design buildings and will ensure that the book will continue to be an important reference for many years to come.
