CP Shift Analysis
The critical path has shifted from Civil earthworks to the Mechanical package. STR.020 (Bridge Deck Formwork) is running 8 weeks late due to delayed rebar delivery from the sole-source supplier. This directly delays MEC.010 start, cascading 22 calendar days onto the mechanical sequence.
Mitigation Actions Required
- Accelerate STR.020 — deploy 2nd formwork crew by 14 Mar 2026
- Pre-order MEC.010 structural steel: 6-week lead time at risk
- Review ELE.040 predecessor logic — SS+10d lag may be compressible
- Commissioner schedule review with Owner by 20 Mar 2026
