Where these numbers come from
Basis
Crosshole sonic logging (CSL) access tubes. 58 public bids on 12 lettings and 12 pay lines, from MassDOT (2019–2025). Every bid is restated to 2026 dollars and to a typical ESC job of 552.5 LF. A letting’s weight halves every 3 years, and each letting counts once, however many bidders it drew.
ESC’s rate is compared as a general contractor carries it: the published typical rate plus 10%, because a public pay line is the general contractor’s price, markup included.
