It is unknown if mechanical splices of other grades of steel reinforcement in special moment frames and special structural walls are capable of resisting stress levels expected in yielding regions in accordance with ACI 318-19 R18.2.7 and this use is beyond the scope of this report.
2.9 Under the 2021 IBC or IRC, the ability of the included mechanical splice systems, when used on Grade 80 reinforcement, to resist forces and provide yielding in the vicinity of the intermediate precast structural wall connections between precast wall panels, or between wall panels and the foundation, in the plastic region in accordance with ACI 318-19 R18.5, has not been determined, and this use is beyond the scope of this report.
2.10 Under the IBC or IRC, mechanical splice systems used in special moment frames constructed using precast concrete are expected to experience flexural yielding in connection regions in accordance with ACI 318-19 and -14 R18.9 (ACI 318-11 and -08 R21.8), and this use is beyond the scope of this report.
This product described in this Uniform Evaluation Service (UES) Report has been evaluated as an alternative material, design or method of construction in order to satisfy and comply with the intent of the provisions of the code, as noted in this report, and for at least equivalence to that prescribed in the code in quality, strength, effectiveness, fire resistance, durability and safety, as applicable, in accordance with IBC Section 104.11.

2.1 Continuous special inspections of the DEXTRA Groutec Precast Splicing System during installation shall be provided by Registered Deputy Inspectors as required by Section 1705 of the LABC. The Registered Deputy Inspector shall verify the following: hardware and equipment; cleaning and condition of the bars in accordance with the specifications and the applicable code; and the installation procedures comply with the specifications and the manufacturer’s published installation instructions.
2.2 The fabricator of the steel couplers shall be required to maintain a detailed procedure for material control and suitable procedures and records attesting that the specified coupler has been furnished. The applicable splice designation (Type 1 or Type 2) or coating, as applicable, shall be included on each packaging assembly prior to shipment from the fabricator’s plant. The fabricator’s identification mark designation shall be established and on record prior to fabrication. Couplers that are not identifiable from marking and test records shall be tested to determine conformity to this report. The fabricator shall furnish an affidavit of compliance and test data shall be provided upon request.
2.3 The DEXTRA Groutec Precast Splicing System shall be selected at the job site by the Registered Deputy Inspector or by the building inspector and shall be tested by an approved testing agency in accordance with Section 1703 of the LABC. The test shall be conducted on each different rebar size and the frequency of tests shall be as follows: one out of the first ten splices; one out of the next ninety splices; one out of the next one hundred splices.

For Type 2 splices, the splice shall develop at least 100 percent of the specified tensile strength of the steel reinforcing bar.
For Type 2 splices only, if failure of the tested splice occurs prior to obtaining the 125-percent of the specified yield strength and the 100-percent of the specified tensile strength, then 25-percent of all couplers shall be tested for both specified yield strength and specified tensile strength. If failure of the tested Type 2 splice occurs with testing of the 25-percent requirement, as stated above, then all couplers shall be rejected.
2.4 Minimum concrete cover and spacing between bars or sleeves shall be provided in accordance with Section 1808.8.2 of the LABC.
2.5 The DEXTRA Groutec Precast Splicing System shall be installed in accordance with the applicable code, manufacturer’s installation instructions, and this supplement.

1.0 RECOGNITION
The DEXTRA Groutec Precast Splicing System described in ER-312 and this Abu Dhabi supplemental report has been evaluated for use as mechanical splices for deformed steel reinforcing bars (rebar) in reinforced concrete structural members. The DEXTRA Groutec Precast Splicing System has been evaluated for structural performance properties, subject to the requirements in ER-312 and this Abu Dhabi supplemental report. The DEXTRA Groutec Precast Splicing System were evaluated for compliance with the following codes and regulations:
• 2013 Abu Dhabi International Building Code (ADIBC)
2.0 LIMITATIONS
Use of the DEXTRA Groutec Precast Splicing System recognized in this supplement is subject to the following limitations in addition to the limitations shown in ER-312:
2.1 The DEXTRA Groutec Precast Splicing System described in ER-312, complies with Chapter 19 of the 2013 ADIBC, given the design and installation are in accordance with the 2009 International Building Code® (IBC).
2.2 The specified compressive strength of concrete, f′c shall not be less than 24 MPa (3,480 psi), when used in special moment frames and special structural walls in accordance with Section 21.1.4.2 of Appendix L in the 2013 ADIBC.
2.3 For structures regulated by Chapter 21 of ACI 318-08, as required by Section 21.1.5.2 of Appendix L in the 2013 ADIBC, where the DEXTRA Groutec Precast Splicing System is designed to resist earthquake-induced flexure and axial forces in frame members, structural walls, and coupling beams, mill certificates complying with ASTM A706M or BS EN4449 Class C, ASTM A615M Grades 280 and 420 or BS EN 4449 Class A or B reinforcement shall be submitted to the building official as evidence that the steel reinforcing bars are compliant.
2.4 Special inspection of the headed bars shall be provided at the jobsite as required by Sections 1704.4 and 1709.1 of the 2013 ADIBC. The special inspector is responsible for verifying identification of the deformed reinforcing bars, grade and size of reinforcing bars, proper joining of reinforcing bars with the precasted couplers as well as placement of the precasted coupler.
2.5 This supplement expires concurrently with ER-312.
