<br />that utilized additional aggregate base CL 5 was for specific locations which required a thicker section of base in order to
<br />correctly match into existing driveways, Particularly in areas where the roadway was being lowered, extra CL 5 was
<br />needed to smoothly transition into existing areas. These areas included portions of Siems Court, Ridgewood Road, and
<br />Skiles Lane and equated to an additional 266 tons for a total of 1,386 tons of additional aggregate base CL 5,
<br />
<br />The special walk item is used for the reconstruction of resident owned walking surfaces or stairs damaged during
<br />construction, Due to either unforeseen field conditions or specific requests by residents, three additional properties
<br />reqnired either walking surface or stair reconstruction, two on Siems Court on one on Skiles Lane,
<br />
<br />The project specifications indicate that bituminous density is to be tested for all roadways, The density should meet the
<br />standard specifications of MNIDOT requirements. If the density exceeds the MNIDOT requirements, a bonus is given to
<br />the Contractor, conversely, if the density is below the MNIDOT requirements then deductions are imposed. The density
<br />tests for the bituminous on this project showed that overall the densities were below the MNIDOT requirements which
<br />means a deduction shall be imposed. This is shown as a lump sum item below,

<br />Schedule B - Storm Drainage
<br />There were Contract Items where additional quantities were needed to complete construction, these items include:
<br />raingarden grading and sodding, type lawn. The raingarden grading item over-ran the contract quantity because of resident
<br />requests regardiug size or shape and also because two raingardens were dug deeper than specified in the plans in order to
<br />create the most efficient drainage situation possible. The sodding, type lawn item over-ran the contract quantity because
<br />work along Lake Johanna Boulevard was more difficult than originally anticipated due to the fact that the actual location of
<br />existing private utilities covered a broader area than what was identified by the utility companies, Consequently, storm
<br />sewer construction and dirt spoil piles impacted a larger area which then required more restoration and sodding,
<br />
<br />There was also a change in the size of the culvert pipe draining the wetland south of Lake Johanna Boulevard to Lake
<br />Johanna. The original plan had a 29"x18" concrete arch pipe which was changed to a circular 30" pipe. The 30" concrete
<br />pipe quantity was accounted for in Change Order No. 1 while the two pipe aprons and trash guards were not. The pricing
<br />for the 30" aprons and trash guards is higher than the 29"x18" and so the approved prices are included below.
<br />
<br />Items 5 - 9 below represent lump sum work items for proposed storm sewer performed by the Utility Contractor during
<br />construction. These were regarded as necessary due to unforeseen existing conditions and approved by the City during
<br />construction, The description of the lump sum items are included below:
<br />
<br />1. Raingarden Grading 88.7 CY $ 14,OO/CY
<br />2. Sodding, Type Lawn 708 SF $3.20/SF
<br />3. 30" RC Pipe Apron 2 Each $2,492/Each
<br />4, Trash Guard for 30" Pipe Apron 2 Each $l,OOl/Each
<br />5, Modification of Catch Basin 6-1 and 12" outlet pipe to accommodate
<br />existing sanitary sewer service
<br />6. mstallation of 4" pipe drain from raingarden to Manhole 3-5
<br />at Arden Place and Ridgewood Road
<br />7, mstallation of additional Catch Basin adjacent to Manhole 1-3
<br />at Siems Court and Lake Johanna Boulevard
<br />8, Replacement of newly installed Catch Basin 6-1 with a 48"
<br />Manhole to better align with curb
<br />9. Modification of Catch Basin for 8-1A and 8-3A to better
<br />match curb elevation
