If you’ve bid an FDOT project, a Florida county road project, or a large commercial site close to a public ROW, you know that Maintenance of Traffic (MOT) – the plan, the equipment, and the labor – can move your bid 5-15% in either direction. Done well, your MOT plan saves duration, reduces conflict with the owner, and lets you keep crews productive. Done poorly, it stacks delay claims and rebid risk on the schedule.
Here’s how we think about MOT when we’re scoping subcontract work for primes across Florida.
MOT is a deliverable, not an afterthought
FDOT Section 102 (Maintenance of Traffic) is its own pay item on every roadway and bridge project. It’s not bundled into the asphalt or milling line items. That means:
- The MOT plan has to be designed, stamped where required, and approved by the owner’s representative before any work in the ROW
- MOT setup and takedown is paid by lump sum, day, or unit – depending on the contract
- Failure to maintain MOT correctly is grounds for stop-work orders and can trigger CCO (Construction Change Order) disputes
For commercial site work that doesn’t fall under FDOT specs, MOT is typically handled under the prime’s general conditions or as a specific subcontract scope. Either way, it’s pay-able work and should be priced accordingly.
Three things that move bids
When we price our portion of an MOT-heavy project, three line items drive the most variance:
1. Lane closure duration and timing. Daytime closures on collector roads can require 4-6 person crews with multiple flag stations. Nighttime closures (where allowed) typically run leaner but pay premium labor rates. The CPM schedule and the owner’s permitted work windows determine which one applies – and the bid pricing follows.
2. Sign rental and arrow-board mobilization. Long-duration projects (90+ days) move toward purchased or rented MOT equipment staged on-site. Short jobs (under 14 days) rely on daily mobilization. The crossover point varies but matters for cash flow on the bid.
3. Traffic Control Plan complexity. A simple shoulder closure on a low-volume road can be a one-page TCP. A complex urban arterial reconstruction can require a full PE-stamped TCP package, phased detour plans, and MUTCD-compliant signage drawings. The engineering cost is real and should be in the bid.
Where Florida MOT differs from other states
Three Florida-specific considerations:
- Hurricane season clauses in FDOT contracts require MOT teardown and storm-prep at specific wind-speed thresholds. The associated mobilization and demob need to be in the bid.
- Snowbird season traffic (roughly December-April) significantly affects ADT counts and acceptable lane-closure windows in coastal counties. A summer-priced MOT plan executed in February might require extended duration and additional flag staff.
- State and county pedestrian safety requirements vary. Some FL counties have adopted MOT requirements above FDOT minimums for pedestrian-crossing protection. Check the local owner spec.
How VLJ partners on MOT
We don’t typically design MOT plans – that’s the prime’s traffic control subcontractor, often a specialist firm. But we work with our primes’ MOT teams on:
- Productivity stacking – sequencing milling, paving, striping, and sealcoating activities to minimize cumulative ROW occupancy
- Equipment staging – coordinating where tri-axle dump trucks, milling machines, and pavers sit during active and inactive shifts to minimize cone-protected staging area
- Schedule reliability – committing to start/end times that match the MOT-permitted windows, so the prime can hold flag crews accountable on their own line
