Committee hears several large project cost increases and schedule notes, including Killington and I‑91 ledge stabilization

Lawmakers pressed agency presenters for specifics about several large projects where estimates changed or the scope requires substantial work. Rogacic said the Killington Stockbridge project met the agency’s 10G3 threshold (an increase of $10 million or 100% relative to preliminary estimates) because preliminary cost estimates dated from 2014, the scope expanded to add drainage and box‑culvert work, and inflation raised the current estimate; he added the agency is reviewing treatment options and expects a possible cost reduction but had no firm revised number on the record.
