CRANE RENTAL COST CODE BY LIFT: THE CRANE CLOCK
Crane and equipment cost rides every erection day, sequence changes reshuffle picks, and site-readiness failures idle the most expensive spread on the project.
This page covers one problem. The full picture for this trade, including the other places margin leaks, is on the structural steel operating system page.
WHERE THE MONEY GOES.
Crane and equipment cost rides every erection day, sequence changes reshuffle picks, and site-readiness failures idle the most expensive spread on the project. Erection delay causes are usually upstream: "foundation issues, incomplete inspections, poor crane access, and site conditions that aren't ready when steel arrives. Erection crews are rarely the source of delays when prerequisites are properly handled.".
THE COST, SOURCED.

THE NUMBER TO MEASURE IT AGAINST.
Structural Steel contractors run about % net profit at $1M to $5M, rising to roughly 10% at $5M to $10M. The CFOS target at $1M to $5M is10%, set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher. A problem like this one lives in the distance between those two figures rather than in a loss on any single job.
Gross margin over the same bands runs % to 24%, against a CFOS target of 10%.
THE SYSTEM THAT FIXES THIS.
Cost codes built against the estimate, so a job can be read while it runs.
