Description
This guide lists industry-standard tolerances and presents recommendations for mitigating tolerance conflicts related to embedded items, elevator cores and hoist ways, openings in slabs and walls, manufactured couplers and splicing systems for reinforcing bars, stairs, cladding systems, infill wall systems, surface accessibility components, finish floor coverings, and expansion joints. Evaluating tolerance compatibility can be challenging due to the variety of materials, products, and elements that interface with, or connect to, concrete construction. Failure to accommodate these varying tolerances could have a significant impact on construction quality, cost, and schedules. Architects and engineers can use these guide recommendations to accommodate individual material, product, and element tolerances at their interface with concrete construction. Contractors can use these guide recommendations to mitigate tolerance conflicts during the construction phase.
Keywords: construction; embedded items; foundation; reinforced concrete; specification; tolerance; tolerance compatibility.
