JOB SELECTION, BID-NO-BID FRAMEWORK

NOT EVERY JOB WORTH WINNING IS WORTH BIDDING.

QUICK ANSWER

Most subcontractors bid on work they can execute. The right question is whether they should. A $2M project that pulls crew away from two profitable $600K jobs, consumes 40% of bonding capacity, and requires 90-day mobilization capital the company doesn't have is a bad bid even if the margin estimate is 26%. The bid-no-bid decision is a financial decision, not just an estimating one.

Winning isn't free. Every bid you send commits estimating time, mobilization cash, bonding capacity, and crew hours before the first pay app goes out. Those four things are finite, and spending them on the wrong job means they're unavailable for the right one that comes up next month. So the question in front of a bid isn't whether your crews can build the scope. It's whether the business can fund the job from mobilization to first payment without borrowing on short notice. That's a balance sheet question, and the estimator can't answer it alone.

THE DEFINITION

WHAT IT MEANS.

A bid-no-bid decision is a financial decision about whether your company can fund, bond, and staff a job, not just an estimating decision about whether your crews can build it.

THE FOUR FINANCIAL QUESTIONS

WHAT TO ASK BEFORE THE BID GOES OUT.

01

Does the company have the working capital to execute it?

Mobilization capital covers crew payroll for the first 30 to 45 days before first billing, material deposits, and bonding fees. All of it has to be funded from working capital or the line of credit. On a $1.8M project with $120K in mobilization cost and a $650K working capital position, the job consumes 18% of available working capital before a dollar of revenue comes in. Is that the right use of the money this month?

02

What does it do to bonding capacity?

Surety aggregate bonding is a finite resource. A $1.5M project on a $7M aggregate bond consumes 21% of bonding capacity. If there are already $4.5M in active bonded projects, this one takes the committed total to $6M and leaves $1M of headroom. Is there work in the pipeline that needs that remaining $1M? Bidding this job may mean turning down a better one next month.

03

What's the crew impact?

A specialty sub with a strong foreman and two proven crews can manage two $600K projects at the same time. Adding a $1.2M project means either splitting the proven crew, which usually cuts productivity on all three jobs, or hiring new crew that doesn't produce at the same rate. The margin estimate on the $1.2M project assumes the proven crew is on it. Field delivery may not match that assumption.

04

What's the realistic win probability and margin?

Win probability on a competitive bid in a trade where the company has strong relationships is 25 to 35%. Win probability on a bid type where the company has won once is 10 to 15%. The expected value of the bid, meaning win probability times estimated margin, should clear the cost of putting the estimate together plus the opportunity cost of the estimating time. Low-probability bids on jobs with marginal margins shouldn't use up senior estimating time.

THE MATH

WHAT IT LOOKS LIKE IN DOLLARS.

Civil and heavy highway

The bid-no-bid question for civil work is equipment utilization first. A job that pencils at 24% gross margin but needs iron that's already committed elsewhere is a rental bill plus a margin, whatever the 24% says. Civil contractors should do the equipment availability check before the estimate starts, not after the award.

Concrete

For concrete subs the constraint is crew capacity at the pour schedule peak, which is the week that breaks first. A bid that overlaps two other projects pour weeks means overtime, rented labor, or a blown schedule. The financial analysis has to model peak-week labor demand across the whole portfolio, not just whether the new job is profitable on its own.

Electrical and mechanical

Electrical bid decisions hinge on the billing cycle of the work type. Rough-in heavy projects front-load cash needs, while trim-heavy and service work bills faster. An electrical sub with thin working capital should weight bids toward fast-billing scopes even at slightly lower margin, because the cash cycle is part of the price.

SWPPP and erosion control

Multi-site SWPPP work changes the math entirely. A 14-site maintenance contract at decent margin can be worth less than 6 sites at the same margin if the travel time and mobilization between sites uses up the labor budget. Site density is a financial variable. Bid-no-bid for SWPPP needs a cost-per-site-visit model, not just a contract-value margin.

HOW SPM BUILDS IT IN

WHAT WE PUT IN FRONT OF YOU.

Active backlog and capacity picture updated monthly

The CEO Report shows current signed backlog, crew utilization by team, and available bonding capacity every month. Before a bid goes out, the owner knows whether the company has the capacity and the capital to build it profitably. That answer comes before the bid, not after the award.

Working capital impact modeled for large bids

For bids above a threshold, typically 15 to 20% of monthly revenue, we model the mobilization capital requirement and its effect on the cash forecast before the bid goes out. The owner sees what winning the job does to cash before the price gets submitted. Nothing about that number is a guess.

Bonding capacity tracked as a constraint

Available bonding capacity is kept current every month: the aggregate bond limit minus the value of active bonded projects. Each bid gets measured against what capacity is left. When capacity drops below a set floor, new bids trigger a conversation about which active jobs are close to completion and will release capacity back.

COMMON QUESTIONS

FREQUENTLY ASKED.

It's mobilization capital. Most subcontractors evaluate whether they can build the work. Fewer evaluate whether they have the working capital to fund the hole between mobilization and first payment, which is 30 to 60 days. A company can win work it can't afford to start without borrowing on short notice.

Sometimes, yes, as long as the draw is planned, the amount is inside your capacity, and the repayment timeline is clear from the billing calendar. The problem is the unplanned draw. That happens when a job gets bid without modeling the mobilization capital requirement, the line gets pulled on short notice, and nobody can say when it gets paid back because no cash forecast was built before the job was committed to.

It costs in two ways. The direct cost is that winning a job the company was underequipped to build produces margin below the estimate. The indirect cost is that the estimating time, mobilization capital, and bonding capacity spent on the wrong job weren't available for the right one. Opportunity cost in construction is real money, and winning the wrong work at the wrong time can crowd out profitable work that opens up the following month.

Yes, with open eyes and a specific reason. Keeping a core crew busy through a slow quarter at 12% margin can beat layoffs and rehiring costs. Buying into a new GC relationship with sharp pricing on the first job can make sense if the pipeline behind it's real. What hurts subcontractors most is low-margin bids they thought were high-margin bids because the overhead rate was wrong. Bid low on purpose or don't bid low at all.

It's a price adjustment, not just a risk note. A GC that pays in 75 days instead of 35 forces you to fund 40 extra days of labor and material float, and that float is a real financing cost, roughly 1 to 2% of contract value depending on your cost of capital. SPM clients keep a GC scorecard covering average days to pay, change order approval behavior, and retainage release speed. Slow-pay GCs see higher numbers in the bid. That is the cost of their money.
