Key Risks
Risk                    Likelihood                           Mitigation
Existing underground utilities conflict          M       During design:
with PLB foundation placement.                        Obtain record drawings and IAF as-builts
Perform site investigation
Use information obtained above to locate foundation
Evaluate spread or drilled footing to avoid utilities
Manufacturer lead time for PLB               H       Confirm lead times immediately following the execution of
equipment may exceed planned                     the TRA. Monitor fabrication and delivery. Proceed with
duration.                                              construction only when delivery dates confirmed.
Schedule conflict with other airport            H       Fast track schedule as possible to complete project prior to
project gate closures planned in Q1-Q2                 other gate closures planned in May 2022. Evaluate impacts
2022.                                             of the gate closure when gate scheduling information
becomes available. Determine a decision point as project
and gate scheduling becomes known.
