Book Description: How does an architect, engineer or builder determine how much a standard I-beam will deviate in length when incorporated into a building design? Or how much a precast concrete wall will shrink in normal temperatures? This graphics-based reference considers allowable tolerances for major building components and construction systems, including accumulated dimensional variations. Included are standard tolerances that minimize pre-construction problems, settle worksite disputes, aid in construction supervision and save time and money at every stage of building.
