Engineer recommends reclaiming waviness-prone streets; council to authorize change order
Summary
KLJ Engineering reported majority of base paving complete but recommended reclaiming a problematic roadway section and a 3-inch overlay at an estimated $42,800; Strata requested an Oct. 15 completion date and a change order will be forthcoming, with costs covered by project contingency.
KLJ Engineering representative Jeff Daley briefed the Grafton City Council on Sept. 9 about the status of local street projects and a recommended change in paving approach to correct a waviness issue on a segment of road.
Daley said the base-bid paving is substantially complete, with utility adjustments finished; concrete testing results are pending before cones can be removed. For one street where level paving could not fully correct waviness, Strata (the contractor) proposed reclaiming pavement — milling up to 4 inches of asphalt and roughly 2 inches of underlying aggregate, blading the material to reestablish cross slope, and placing a 3‑inch overlay. Daley reported Strata’s estimate for reclaiming 6 inches and repaving would come to approximately $42,800.
Administrator Nick Ziegelmann said the $42,800 estimate is accounted for within the project’s contingency, and a formal change order will be brought forward. Daley also said Strata requested extending the completion date to Oct. 15 from the original Sept. 26 date to accommodate the additional work.
Why it matters: the reclaim-and-repave approach is the selected option to correct pavement waviness and avoid recurring surface issues; the change will affect the project schedule and utilize contingency funds.
Next steps: city staff will process a change order reflecting the reclaiming work and revised completion date; testing results and final timelines will be posted once available.
