Transportation estimating for roads, rail and traffic systems priced to DOT pay items
Transportation work is bid on pay items, and every item has its own unit, measurement rule and specification section. LEEDS estimators measure pavement by the ton and square yard, striping and guardrail by the linear foot, signals and signs by the each, and carry maintenance of traffic as the production constraint it really is. The result is a schedule of prices that reconciles to the owner's bid form.

Overview
How transportation work is measured and priced
A transportation estimate converts roadway plans, typical sections, signing and marking sheets and signal plans into a bid schedule. Pavement is taken off by layer: milling in square yards, asphalt lifts in tons using the section thickness and mix density, aggregate base in tons or cubic yards, and concrete pavement in square yards by thickness. Drainage, curb and shoulder work follow the same measurement rules as the specification. Bid schedule totals are tied to plan sheets, specification sections and bid addenda so every number can be audited.
The systems that make a roadway function are priced as discrete items. Traffic signals are counted by pole, mast arm, controller cabinet, detector loop and conduit run. Signs are counted by panel and post, striping measured by linear foot and color, and guardrail by length with terminals and anchors counted separately. Rail and transit elements add track, ballast, ties and crossing panels. Production is adjusted for traffic exposure, since a crew working beside live lanes moves slower than one inside a closed work zone, and each lift of asphalt is tied to plant distance and haul time so paving crew idle time shows up honestly in the price.
Maintenance of traffic drives both cost and schedule. We build MOT from the phasing plan, pricing devices, arrow boards, flaggers and nighttime premiums so the production assumptions match what the lane closure windows will allow. The final schedule keeps each pay item's unit price, extension and supporting calculation together, with notes on measurement rules, plan quantity changes and addenda. That structure makes the bid easy to review before submission and gives you a defensible record if the owner questions an item later, adjusts quantities or issues a supplemental agreement during construction.

How our estimating process works
Four steps from upload to a bid-ready estimate, with a senior estimator signing off before anything leaves our desk.
- 1
Upload plans and scope
Send your drawings, specifications and bid invitation through the secure upload form. We confirm scope, deadline and a fixed price within two business hours.
- 2
Digital quantity takeoff
Estimators measure every item from calibrated plans in Bluebeam and PlanSwift, color-coding each layer so quantities can be traced back to the drawing.
- 3
Pricing and labor
Quantities are priced with location-adjusted material costs, crew productivity rates and equipment, then marked up to your overhead and profit targets.
- 4
Senior review and delivery
A second estimator audits quantities and pricing, documents assumptions and exclusions, and delivers your Excel workbook, PDF summary and marked-up plans.
Why LEEDS
Why contractors switch to LEEDS
An estimating desk that behaves like an extension of your team, not a software subscription.
Pay items carried with the owner's numbers, units and measurement rules, so your schedule reconciles with the engineer's estimate.
Asphalt computed in tons from section thickness, and mix density instead of a rough square-yard rate that ignores layer depth.
Maintenance of traffic built from the phasing plan, including night work, flaggers and device rentals, not a flat percentage.
Signals, signs and striping broken out so, electrical and marking subcontractors can take their scope directly.
Guardrail terminals, transitions and anchors, counted separately from run length, where bids are often short.
Rail, transit and Division 34 specialty items, covered, including track elements and crossing panels.
Fuel, binder and aggregate prices indexed, to current supplier quotes with escalation clauses called out.
Quantity reconciliation reports that explain, every difference from the bid form to the plan quantity.

FAQ
Transportation Estimating FAQs
How do you convert paving areas into tons?
We multiply the measured area by the lift thickness and the mix density from the specification, then add allowances for tapers, joints and waste. Each lift is shown separately, so surface and base courses can be priced, ordered and invoiced against their own pay items. Waste and tapers are shown on a separate line.
Do you price to the state DOT pay item list?
Yes. We use the item numbers, descriptions and units from your bid form and follow the measurement and payment rules in the specification. If a plan quantity differs from the engineer's schedule, we flag it and show the reconciliation. Where the engineer's quantity looks wrong, we show the measured figure beside it so you can decide whether to bid the plan quantity or raise it.
Can you handle maintenance of traffic as a separate line?
Yes. We build it from the traffic control plan and phasing sequence with devices, signs, flaggers, arrow boards and night work. When the owner pays it as a lump sum, we show the supporting calculation so you can adjust it if production changes. It also helps to send the phasing narrative, which often controls how long each lane closure can stay in place.
Do you estimate traffic signals and ITS?
We count poles, mast arms, heads, controllers, detection, conduit, pull boxes and cable from signal plans, and price labor by crew day. Fiber and communications scope is captured when it appears in the plan set and specifications. Controller cabinets and utility service points are listed separately because the power company often controls their schedule.
Do you include rail and transit work?
We quantify track, ties, ballast, crossing panels, platforms and related Division 34 items from track and station plans. Specialized vendor items such as signal houses or catenary are carried from supplier quotes and flagged as allowances. We note which items need bonded vendors or specialty crews.
What turnaround should we expect?
Most roadway packages are delivered in 48 to 72 hours after we receive the full plan set, specifications and addenda. Multi-mile corridors are scheduled individually, and rush service is available for letting deadlines. We confirm the date and scope before starting. Larger corridors are phased by segment, with early segments often returned first.
