ment of concrete, and erection tolerances. 3.8.4-6 Draft Revision 4 – December 2012 Special construction techniques, such as modular construction methods, if proposed, are reviewed on a case-by-case basis to determine their effects on the structural integrity of the completed structure. In addition, the applicant should provide the following information: A. The extent to which the materials and quality control programs comply to ACI 349, with additional criteria provided by RG 1.142 for concrete and ANSI/AISC N690-1994 including Supplement 2 (2004) for steel, as applicable B. If welding of reinforcing bars is proposed, it should comply with American Society of Mechanical Engineers (ASME), Boiler and Pressure Vessel Code (Code) Section III, Division 2. Any exception to compliance should be supported with adequate justification. 7. Testing and Inservice Surveillance Programs. For Seismic Category I structures outside containment, the staff reviews information on structures monitoring and maintenance requirements. For Seismic Category I structures, it is important to accommodate inservice inspection of critical areas. The staff reviews any special design provisions (e.g., providing sufficient physical access, providing alternative means for identification of conditions in inaccessible areas that can lead to degradation, remote visual monitoring of high- radiation areas) to accommodate inservice inspection of other Category I structures. Postconstruction testing and inservice surveillance programs for other Category I structures, such as periodic examination of inaccessible areas, monitoring of ground water chemistry, and monitoring of settlements and differential displacements, are reviewed on a case-by-case basis. 8. Masonry Walls. Areas of review pertaining to masonry walls should include, at a minimum, those items identified in Appendix A to this SRP section. 9. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and
