Board presses for tighter contractor timeline as river work window narrows
Summary
Board members and a presenter stressed that tree cutting must finish by Sept. 30 and river engineers will only allow a narrow in-stream work window; staff said mobilization and pipe assembly can occur ahead of that but in-stream work becomes costlier if delayed.

Board members and a presenter flagged seasonal constraints on in-stream construction, urging the selected contractor to meet a tight schedule tied to a Sept. 30 tree-cutting deadline.
"They also are very aware that tree cutting is September 30 and the river engineers are gonna give them a small window after that to work in the river," Presenter (S4) said, noting contractors generally avoid extended in-stream work because costs rise the later they work in the season.
Committee member (S3) asked whether work could begin before tree cutting; Presenter (S4) said crews can remove concrete and start back-slope prep and that assembling pipe would take about a week with a crew of four to five. The board discussed sequencing — cutting six cedar trees on the embankment to allow concrete removal and excavation — and confirmed related items were included in the bid addendum.
Board members emphasized they expect staff to press the contractor on timeframes during contract negotiations and to coordinate start-of-work dates so in-stream work fits the engineers' window.
