November 9, 2018 County Board Memo Update on Fall 2018 resurfacing Smoothness Problem may be fixed? They were not able to pave anything that was acceptable as far as smoothness till Tuesday, November 6`h. It appears like they may have fixed the problem by changing the settings on the hydraulic actuators from a proportional setting to a different setting. Completion of Wood River Road west of NE Hwv 11 The temperature was too cold Wednesday, November 7th to place asphalt, so it looks like the next day they might be able to pave may be Wednesday, November 14`h. • They have about 1 '/A miles of eastbound top lift (south side of the road west of NE Hwy 11) that is completed and acceptable. • They have 6 '/2 lane miles that are either unacceptable (rough) or haven't been covered with top lift. Following the county specs and NDOT specs, JIL could be allowed to attempt to finish the Wood River Road resurfacing. They are hoping to get the whole 8 lane miles of resurfacing done before winter. • With cold mornings and shorted days, it'll take 5 to 7 days to finish the Wood River Road resurfacing. • I've seen years where contractors are able to place asphaltic concrete past Thanksgiving. • They'll need good weather to get done by Thanksgiving. Work Suspended for Winter They won't make the completion date in the change order of November 9, 2018. • It's too late to start work on the 2 projects in Cairo (One R Road east of NE Hwy 11 and Hillside Drive by golf course). • We'll have to put together a detailed report of working days, weather, etc. for working days and liquidated damages. How to Fix the Rough Road The fix from here is detailed in the specifications. • They have to diamond grind the road smooth, • If they are not able to grind it smooth, they will have to remove and replace the rough asphalt. • We will require a fog seal after any grinding. • A smoothness penalty may be assessed, depending on what will the smoothness is after grinding. The NDOT specifications were piggy backed in our bid specifications, so we're talking to the NDOT for confirmation to ensure we proceed correctly on: • the completion date and liquidated damages, and • the working days and suspension of the work through the winter. Drag Course (bottom lift) through winter The bottom lift is a drag course and is placed to fill in ruts, dips, cracks, smooth bumps, etc before placing the top lift. While it's normal for a drag course to have some drag marks, segregation, surface imperfections, etc, this one is especially ugly. The drag course will fulfill its purpose as long as they can get the road covered before winter. It they are not able to get the road covered before winter, they may have to replace the drag course next spring. Page 2
