Executive summary
Schedule Quality Index — 73 / 100 · below the 75 healthy threshold
Weighted across 14 DCMA-aligned checks. Down 4 points vs the R10 baseline, driven mainly by open-ended logic and constraint usage in the structural steel scope.

Plain-language narrative
The programme scores 73/100, four points below the previous revision and under the 75 healthy threshold. The decline is concentrated in the structural steel scope, where 17 activities now carry negative float — most critically A1422 · Erect columns Grid G, which has slipped 18 days against the R10 baseline and is driving the longest path. Three activities have been re-anchored with hard constraints (above the 2% target), which masks true float and should be replaced with logic where the sequencing is genuine. Open-ended logic sits at exactly 5%, on the warning boundary; closing the successor links on the MEP rough-in chain (A1801 and its siblings) would recover both the open-ends and out-of-sequence checks. Net effect on the forecast finish is a +18 day slip to 19 Nov 2027, recoverable with constraint cleanup and resequencing of the Grid G erection. Every figure in this narrative is traced to the activities listed above.
