RULE NO.:RULE TITLE:

61G15-31.004Design of Cast-in-Place Post-Tensioned Concrete Structural Systems

PURPOSE AND EFFECT: To update existing rule and clarify the responsibilities of the engineer of record.

SUMMARY: Update existing rule and clarify the responsibilities of the engineer of record.

SUMMARY OF STATEMENT OF ESTIMATED REGULATORY COSTS AND LEGISLATIVE RATIFICATION: The Agency has determined that this will not have an adverse impact on small business or likely increase directly or indirectly regulatory costs in excess of $200,000 in the aggregate within one year after the implementation of the rule. A SERC has not been prepared by the Agency.

The Agency has determined that the proposed rule is not expected to require legislative ratification based on the statement of estimated regulatory costs or if no SERC is required, the information expressly relied upon and described herein: The Board determined the rule amendments will have a minimal cost impact which will not exceed $1 million in the aggregate over the next 5 years.

Any person who wishes to provide information regarding a statement of estimated regulatory costs, or provide a proposal for a lower cost regulatory alternative must do so in writing within 21 days of this notice.

RULEMAKING AUTHORITY: 471.033(2), 471.008 FS.

LAW IMPLEMENTED: 471.033(1)(g) FS.

IF REQUESTED WITHIN 21 DAYS OF THE DATE OF THIS NOTICE, A HEARING WILL BE SCHEDULED AND ANNOUNCED IN THE FAR.

THE PERSON TO BE CONTACTED REGARDING THE PROPOSED RULE IS: Zana Raybon, Executive Director, Board of Professional Engineers, 2639 North Monroe Street, Suite B-112, Tallahassee, FL 32303; [phone]

 

THE FULL TEXT OF THE PROPOSED RULE IS:

 

61G15-31.004 Design of Cast-in-Place Post-Tensioned Concrete Structural Systems.

(1) Structural engineering documents shall show the complete structural configuration and loading requirements of the post-tensioned system including: member sizes, nature, type of post-tensioning system, location of all the prestressing tendons (in plans and elevation), and the 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(s), the EOR Engineer of Record shall require the submission of installation drawings for review by the engineer of record. Calculations shall also be submitted by the delegated engineer which show sufficient information to document confirm that the number and size of tendons provided are adequate to carry all loads provide the prestressing forces 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, identify the structure and provide all details of post-tensioned tensioning 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 impressed seal, date, and signature of the delegated engineer who prepared them and shall be reviewed by the EOR engineer of record for the structure. A cover sheet listing the drawings and calculations may be used.

(3) It is the responsibility of the EOR engineer of record 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 engineer of record.
