What is at stake.
No two adjacent bridges can be under traffic restrictions at the same time, and some can close only in summer. Steel and precast girder deliveries set the pace, and the agency has committed to lane closure limits with the public. The program needs one schedule that enforces all of that.
How we control it.
What our schedulers and cost engineers are doing on this project.
Program IMS
All 27 bridges sit in one program schedule, with traffic rules coded so conflicting closures cannot be scheduled.
Girder tracking
Steel and precast girder fabrication is tracked from shop drawings to delivery, tied to each bridge's setting date.
Earned value
Each bridge carries its own cost-loaded schedule, rolled up into program earned value every month.
Risk analysis
Monthly Monte Carlo analysis gives P50 and P80 dates for program completion and for the most critical bridges.
Where it stands.
Twenty-seven bridges is easy to draw and hard to sequence. The traffic rules had to live inside the logic.
