SYSE.4:5.3 - Continuing building under occupied retrofit

The retrofit decision relies on a configuration-specific claim that the continuing building can retain the declared structural performance and occupied-use constraints during one staged change. The challenge combines a model or analysis applicable to that configuration with inspection and monitoring results from the occupied stage. A result obtained for an empty building or another temporary-support arrangement does not carry the same applicability.

The engineering-assurance plan names the claim, OccupiedRetrofitSequenceQuestion-3, the intended analysis and observation Work, the temporary-support and access configuration, the validity window, and the temporary-access branch in SYSE.3 or architecture choice that the practitioner may need to reassess. If monitoring later contradicts the assumed load or access condition, the engineer records that change in the account and reassesses the affected branch or choice. Building acceptance, a permit, contractor authorization, and release of the next Work window remain separate decisions under their own criteria.
