Why Post-Tension Contractors Lose Cash in the Pour Sequence

QUICK ANSWER

Post-tension contractors lose cash in the pour sequence when strand footage never gets costed against the estimate, anchors and couplers get bought in bulk with no job-level tracking, and billing waits on a pour schedule the contractor does not run. CONTROL costs the strand by the foot and bills by dates instead of pours.

THE CASH PROBLEMS

The specific ways post-tension contractors lose cash, pulled straight from what makes this trade different.

Strand Footage Job Costing

Strand is the unit of the trade, and footage installed per crew day is the production number. Tracked weekly, it shows which decks and layouts carry the margin.

Anchor and Coupler Material Tracking

Anchors, couplers, and pocket formers bought in bulk still get installed one deck at a time. Job-level material tracking shows the true hardware cost per pour.

Pour Sequence Billing

Your billing dies when the GC's pour schedule slips. Contract billing dates, independent of pour sequence, keep the pay application moving anyway.

QUESTIONS POST-TENSION CONTRACTORS ASK
Why do post-tension contractors run out of cash mid-project?
Post-tension contractors run out of cash mid-project because billing rides on a pour sequence the GC controls. Material and layout labor go in early, then a schedule slip pushes stressing and the pay application into next month while your supplier terms stay at 30 days. Contract billing dates independent of pours close that hole.
How should a post-tension contractor track materials?
A post-tension contractor should track anchors, couplers, and strand from the bulk purchase to the specific deck they serve, with job-level codes. Chapter 5 of CONTROL aligns the software and bookkeeping so those materials cost to the right job automatically, in about 30 seconds of lookup rather than a month-end guess.
What profit margin should a post-tension contractor target?
A post-tension contractor should target 22 to 30% gross profit per project and 12% net profit after all expenses, with overhead between 9 and 13%. Strand footage per crew day and hardware cost per deck are the two numbers that make those targets a weekly management tool.
