SYSE.3:5.3 - Occupied building retrofit

SYSE.2 supplies the continuing building, the occupied-use claim, and a candidate concept through the occupied region, safe-entry, egress, and essential-service interfaces. C.30 and C.32 supply candidate building zones, service paths, interfaces, and load-bearing relations. Temporary access, work-area isolation, and construction sequencing remain realization and WorkPlan questions.

The first unsupported branch is how a contractor System can reach and change the selected building region while the occupied-use boundary and essential services remain supported. The candidate transformer System is one contractor team. Access-equipment Systems remain separate resources or participating Systems unless their relation to the team is independently established. The missing support is a capability claim under the occupied configuration, access, isolation, load, and service-continuity conditions. The first WorkPlan item is a contractor-capability and temporary-access investigation for those conditions.

If no admissible access arrangement remains, the engineer reopens the C.32 comparison of zones, service paths, placement, and interfaces. The engineer reassesses the linked occupied-use concept under SYSE.2 if continuing occupancy or the use boundary must change. A construction sequence is plan content; it is not the building concept, the changed building, or evidence that the Work has occurred.
