Technical insights on large-context AI, document processing, and real-world applications.
What estimators on Reddit actually say about change orders. On r/estimators, people who price incomplete documents under time pressure occasionally drop the professional filter. What comes out is not thought leadership — it is field notes about what change orders do to an estimator's sense of craft, and to their sleep.

The industry has benchmarked contractor finances since 1989 across a hundred ratios and never measured whether a firm wins work efficiently — which is why the go/no-go decision, the highest-leverage call in preconstruction, is usually made on instinct.

Read more →The fix for missed scope isn't "read harder." It's to change who does the first pass. AI classification reads the entire spec book — every page, every division — and sorts each section by what it is, scoring its own confidence so experts spend their scarce attention only where the risk actually lives.
Read more →A missed spec section doesn't stay missed — it resurfaces as a change order. Across 18,000+ completed U.S. projects, change orders averaged 4–5% of contract value, with the upper band near 15%, and the ones that hurt most are found late. The deeper pattern is that these problems start upstream, in the documents.

It's that reading a thousand pages across fifty divisions, under a three-week clock, with a dozen live bids and a thin bench, is impossible to do perfectly by hand. This is the setup for every change order story you've ever told.
