(1) Structural engineering documents shall show the complete structural configuration and loading requirements of the post-tensioned system including: member sizes, type of post-tensioning system, location of all prestressing tendons (in plans and elevation), magnitude of all prestressing forces, and all design assumptions. Structural engineering documents shall also show all required non post-tensioned reinforcing steel including size, spacing, and lengths required for the post-tensioned system.
(2) If the engineer of record (EOR) elects to delegate the responsibility for preparation of calculations and installation drawings to a delegated engineer for the post-tensioning system, the EOR shall require the submission of installation drawings for review. Calculations shall also be submitted by the delegated engineer which show sufficient information to document that the number and size of tendons provided are adequate to carry all loads shown on the structural engineering documents. The member dimensions and tendon directions shall match those on the structural engineering documents, unless otherwise agreed to with the EOR, via modified structural engineering documents. Installation drawings shall include the following as a minimum: identification of all the structural elements designed by the delegated engineer, all details of post-tensioned and non post-tensioned materials to be used including necessary accessories, and instructions for construction. If the delegated engineer utilizes or requires any additional reinforcing to maintain the member sizes shown on the structural engineering documents, the delegated engineer shall inform the EOR. If any moments, shears or axial loads are required for the lateral force resisting system the EOR shall provide them to the delegated engineer for inclusion in the preparation of the delegated engineering documents. All forces imposed on the load supporting members from the post-tensioned system shall be reported to the EOR. The installation drawings and calculations shall bear the seal, date, and signature of the delegated engineer who prepared them and shall be reviewed by the EOR for the structure.
(3) It is the responsibility of the EOR for the structure to review the post-tensioning system installation drawings together with the shop drawings of all required reinforcing steel needed for a complete structural design.
(4) The effect of post-tensioning on other parts of the structure is the responsibility of the EOR.
