Schedule Compression Detection
200 SS+lag relationships indicate systematic schedule compression by the contractor. Key finding: 76 relationships have lags exceeding 50% of the successor's OD — effectively making them equivalent to FS relationships but masking true logic. 38 negative lags create artificial leads that may not be executable. DCMA 14-point check identifies this as schedule gaming risk.
Recommended Actions
Schedule review workshop with contractor required:
- Convert all SS+lag >50% OD to FS relationships
- Remove or justify all 38 negative lags
- Challenge SF relationships — provide construction methodology
- Require revised baseline submission by 20 Mar 2026
