How does pump truck drag affect concrete flatwork margins?

A line or boom concrete pump truck typically costs a $450-$700 minimum callout fee. If this overhead is not budgeted as direct job expense prior to margin calculations, it strips out hundreds of dollars from net contractor earnings.

What is the loaded labor burden for concrete finishers?

Concrete finishing demands high physical exertion and exposes crews to chemical burns. Workers' comp and employer payroll taxes average 30% on top of base wages, pushing a $34/hr finisher to a $44.20/hr burdened cost.

The Ready-Mix Concrete Pricing Trap

Concrete sets against a ticking clock. If unexpected traffic delays a mixer or an elevation grading issue burns extra crew hours, a thin markup will turn the job negative. On a $4,585 cost slab, bidding with a 28% markup leaves you with just a 21.9% gross margin, bleeding out nearly $500 in rightful profit.

True Margin Formula: Bid = Total Burdened Cost / (1 - Target Margin %)

Example: $4,584.80 / (1 - 0.28) = $6,367.78
