A signal package looks like a handful of poles and a controller — and that's exactly why work gets left out and the long-lead unit prices get gamed. Bid Reasoner normalizes every electrical and traffic-signal sub bid to your scope of work, scores it across six dimensions, and runs four deterministic risk rules over the pole, mast-arm, and mobilization lines before you award. It's the trade-level version of our subcontractor bid analysis.
Five to nine signal subs bid an intersection package. One total comes in 18% under the field. On a spreadsheet that bidder looks like the obvious pick — until you read the line items and find no temporary signals, no detection, and testing and turn-on assumed into the GC's scope. The number is low because the work is missing, not because the bidder is sharp.
A signal job concentrates cost in a few long-lead lines — signal poles, mast arms, and the controller cabinet — so a price far off the field on one pole, a front-loaded mobilization, or one omitted item moves the award. By eye, across bids in different formats, you catch some of it. The ones you miss become the change order on the loop detection you thought was included, or the dispute over the temporary signal that was never priced.
Before you compare totals, confirm every bidder priced the same work. These are the items a complete electrical and traffic-signal bid should carry, and the dimension each maps to.
| Line item | Why it matters | Dimension / flag |
|---|---|---|
| Conduit & trenching | Linear-foot underground work; depth, encasement, and restoration vary widely by bidder. | Price · scope |
| Pull boxes & junction boxes | Counted items that are easy to undercount; confirm quantities match the plans. | Scope · gap analysis |
| Signal poles & mast arms | Long-lead, high-value items; the unit price per pole drives the bid. | Price · peer outlier >2× / <0.5× |
| Signal heads | Counted by approach and movement; a low count is a scope gap, not a saving. | Scope · price |
| Detection (loops / video) | Loop or video detection is routinely assumed away or pushed to the GC. | Scope · gap analysis |
| Controllers & cabinets | Major lump item; cabinet type and controller spec must match the contract. | Price · compliance |
| Conductors & wiring | Linear feet of signal and power cable; gauge and circuit count vary by bidder. | Price · scope |
| Grounding | Small line, easy to omit — but a missing grounding system is a failure mode, not a saving. | Scope · gap analysis |
| Roadway lighting | Sometimes split to a separate sub; confirm who carries the lighting scope. | Scope · compliance |
| Temporary signals | A real cost during construction; frequently omitted and a large schedule line. | Scope · schedule |
| Testing & turn-on | Frequently pushed to the GC's scope; price the activation explicitly. | Compliance · gap analysis |
These are the lines that quietly drop out and make a total look low. Bid Reasoner's two-way scope-coverage gap analysis surfaces each one against your scope of work.
Maintaining traffic through construction is a real cost that's easy to assume away. A bidder that didn't quote it isn't cheaper, it's short scope.
Loop or video detection is routinely folded into another line or pushed to the GC. Its absence is a scope gap, not a price advantage.
Activation and acceptance testing is pushed to the GC more often than any other line. If it isn't priced, that cost lands on you after award.
A small line that's easy to drop — until the system fails inspection. A thin or missing grounding line is a compliance and scope risk.
Every electrical and traffic-signal bid runs through the same four deterministic rules, with fixed numeric thresholds. Long-lead poles and mast-arm unit prices, plus allowances carried for utility coordination, are where the spread and the risk concentrate.
Signal crews stage early, so an inflated mobilization line is the classic front-load — cash recovered before a pole is set. Flagged when mobilization exceeds 10% of the total.
With most cost in long-lead poles and mast arms, a per-pole price far off the field — high to chase a quantity overrun, low to win — moves the award. Flagged above 2× or below 0.5× the peer median, and at or below $1.00.
A total that lands more than 20% off the field is flagged — and paired with the scope gap, it shows whether the bidder is sharp or simply carried a thin utility-coordination allowance and left detection out.
Upload or forward every electrical and traffic-signal sub bid for the package. Bid Reasoner reads each PDF, extracts the line items, and normalizes them to your scope of work so the poles, mast arms, conduit, detection, and turn-on line up item for item — even when each bidder's form looks nothing alike. Every bidder is then scored across price, scope, schedule, compliance, performance, and risk, and the four deterministic rules run over the numbers.
The scope-coverage gap analysis surfaces the temporary signals, detection, testing, or grounding a bidder didn't quote — the difference between a sharp number and a short one. Every score links to a page-cited quote from the source bid, so the answer to "why this electrician?" is on the record. Recommend a winner under any of 7 decision modes — from Lowest Responsible Bid to Best Value — with a confidence score, and carry the reasoning, the risk flags, and any forced override straight into the award memo with a full audit trail.
A complete electrical and traffic-signal bid prices conduit and trenching, pull boxes and junction boxes, signal poles and mast arms, signal heads, detection (loops or video), controllers and cabinets, conductors and wiring, grounding, roadway lighting, temporary signals, and testing and turn-on. The long-lead poles and mast arms usually carry the largest unit prices, so the price per pole and per mast arm is where the bid is won or lost. Bid Reasoner normalizes each bidder's line items to your scope of work so you can see, item for item, who priced what.
Temporary signals, detection, testing and turn-on, and grounding are the items most often missing from an electrical and traffic-signal bid. They are easy to assume into another line or push to the GC, and a frequent reason one bidder's total comes in low. Bid Reasoner runs a two-way scope-coverage gap analysis on each bidder — items in your scope the bidder didn't quote, and items the bidder priced that weren't in your scope — so the low number that's low because it left work out gets caught before award.
Bid Reasoner runs four deterministic risk rules over every electrical and traffic-signal bid. It flags unbalanced unit prices at or below $1.00, line items above 2x or below 0.5x the peer median — the long-lead pole and mast-arm unit prices where games hide — totals that deviate more than 20% from the field, and mobilization above 10% of the total, the classic front-loaded bid. These are fixed numeric thresholds anyone can check, not a black-box score.
Built-in state-DOT pay-item baselines exist for select states — NY and NJ — as a head start on the signal and lighting items, with peer-median normalization everywhere else. Outside those states, Bid Reasoner levels each electrical and traffic-signal bid against the other bids in your package, so no government pay-item data is required to start. Bid Reasoner analyzes the bids you receive; it is not takeoff or quantity-estimating software.
Bring one package's electrical and traffic-signal sub bids. We'll normalize them to scope, score six dimensions, flag the pole, mast-arm, and mobilization risk, and recommend a winner on the call.
