Description
Early definition of construction tolerance expectations is an important step in the design process of a project. Designs should consider tolerances of all materials and systems for their integration into a constructable facility. This session presents case studies, best practices, and material tolerances for design strategies to best achieve a constructible structure. Presentations will include how vertical building tolerances effect other building tolerances of tall reinforced concrete buildings and cover and thickness tolerances of slabs placed on expansive soils using control void forms.

Learning Objectives
• Describe tolerances of vertical concrete elements, such as columns and walls, for multi-story buildings that are found in ACI 117 and AISC publications.
• Explain potential solutions to achieve a buildable facility, when current ACI 117 tolerances for multi-story structures are in conflict with other building systems such as elevators or exterior enclosure, or other architectural floor plan items.
• Recall some surveying measurement challenges, such as determining the right datum point in a construction site and measuring location of proper job site datum under changing conditions.
• Identify critical, key components, such as slab thickness tolerances coordinated with reinforcing mat cover tolerances, of a reinforced concrete slab placed on expansive soil with void forms supporting the slab during construction.
