Zusammenfassung:	An annular shroud assembly (20) for a gas turbine engine (10) includes a plurality of first shroud segments (21A) having a same first arcuate length within a tolerance, at least one second shroud segment (21B) having a second arcuate length different than the first arcuate length and outside the tolerance, a plurality of first intersegment gaps (22) between adjacent first segments, the first intersegment gaps (22) having a circumferential dimension within a desired controlled range of dimensions, and at least two second intersegment gaps (22) between opposed ends of the second segment and adjacent first segment. The first and second intersegment gaps (22) are within the desired controlled range. Methods for forming such annular shroud assembly (20) are also provided.
