With post-tensioning construction, a minimum clearance of how many inches should be maintained around all blockouts?

In post-tensioning construction, maintaining proper clearance around blockouts is crucial for several reasons, including safety, structural integrity, and ease of installation. A minimum clearance of 15 inches around all blockouts is recommended to ensure that workers can safely maneuver tools and equipment, reduce the risk of damaging the tendons or ducts during construction or when placing concrete, and facilitate proper inspection and maintenance access.

The 15-inch clearance helps prevent complications that could arise from insufficient space, such as interference with post-tensioning cables or unintended stresses on the structural elements. This guideline is part of standard practices in post-tensioning to promote a safe and effective construction process, making it essential knowledge for anyone involved in building contractor work in North Carolina and beyond.
