WHY TUNNEL CONTRACTORS LOSE MARGIN WITHOUT KNOWING IT.
Tunnel margin is lost to three specific things: the baseline ledger, the sleepless burn, and the buried capital. All three are measurable, and all three are invisible without job costing that reads against the estimate.
Tunnel contractors at $1M to $5M net 6.5 percent on the SPM 48-trade dataset, rising to 9.5 percent by $25M to $50M; the CFOS target at $1M to $5M is 10 percent. The distance between the trade average and the CFOS target isn't a pricing problem in this trade. It sits in the three mechanisms below, each of which moves margin without appearing as a failure on any single job. The GBR states what the bid may assume, the DSC clause allocates what differs, and the shift log proves which one happened. Ground documentation isn't paperwork; it's the trade's second set of books.
THE MATH BEHIND THE MISSING CASH.
The Baseline Ledger
The GBR states what the bid may assume, the DSC clause allocates what differs, and the shift log proves which one happened. Ground documentation isn't paperwork; it's the trade's second set of books.
The Sleepless Burn
Continuous operations mean the daily cost never pauses while the advance rate does. Downtime coded by cause (ground, machine, logistics, owner) is the only way the stopped-heading argument ever pays.
The Buried Capital
The machine and plant are project-scale capital with salvage assumptions built into the bid. Cost-basis honesty (ownership, refurbishment, residual) decides the price before the ground gets a vote. (cfos-working-capital-system) ---

Industry figures are Tunnel contractors' AVERAGE for each revenue band, not a floor. The CFOS net profit target is set at 10 percent before taxes or 3.5 points better than your trade's average at your revenue, whichever is higher, and the gross margin target is set at whatever gross margin produces that net profit once your overhead is paid, and never below your trade's own average. Gross minus overhead equals net on every column, so the rows tie out. The gross margin and overhead figures for this trade are derived from the nearest comparable trade in the same dataset, and were not measured directly.
