title
Certificate for Payment No. 1 for $229,351.22 to Duininck, Inc. and Certificate of Substantial Completion RE: T.H. 75 Storm Sewer Improvements
body
Duininck has completed the storm sewer work on T.H. 75. The total working days charged for the project was 30 (30 allowed). The detour portion of the project took 16 working days (15 allowed). For now, DGR has not included any liquidated damages, but this could be included in the final pay request if the council wishes to charge them ($900/day). Note, the existing pavement section was a little different than what we originally believed due to the center 24’ of the highway being asphalt over concrete vs the entire width of the road being asphalt over concrete. Because of this, MnDOT required 3-lifts of asphalt (8” thick total) in the areas outside of the center 24 feet. This required the Contractor to pave the asphalt patch over 2 days vs 1 day to allow the asphalt to cool enough prior to placing the next lift. This also reduced the quantity of “Pavement Replacement (Type CX)” by 96.5 S.Y. ~$15,922 and increased the amount of Type SP 12.5 Bituminous Mixture for Patching by 10.64 tons ~$2,766.
recommendation
