s to incorporate the settlement profiles computed for a postulated construction sequence (the various stages of construction and post construction), which a COL applicant can then use for verification purposes in conjunction with predictive calculations (associated with the actual construction sequence) and a settlement monitoring program. The acceptance criteria for these verifications need to be clearly identified. • Development of a short term and long-term settlement monitoring program that can detect both vertical and horizontal movements in and around the structures, as well as differential distortion across the foundation footprint, from the beginning of construction at the site. The movements induced by site excavation, backfill, and re- compaction should be included in the monitoring program. Consideration should be given to maintaining all or pieces of the monitoring program over the life of the structure. ii. In the case of a COL application that incorporates a DC application by reference, the staff reviews the following information: • In addition to the geotechnical investigation performed in SRP Section 2.5.4, the staff reviewer for this section should review, the site-specific geotechnical investigation program to determine predicted settlements during construction and post construction, based on the construction sequence to be used. The investigation program should be carried to sufficient depths to be able to ascertain these properties over the depth considered important to the settlement analyses. The methodology for site-specific settlement analyses should be consistent with the corresponding methodology in the DC application. • Settlement monitoring program to verify whether measured settlements and distortions are consistent with predicted site- specific settlements during construction and post-construction phases, through the life of the structure. • Verification of the interface considerations between DC and COL applications, which
