Exhibit 1
1. Milling Limits definition / explanation
a. The milling activity required of this project will be paid as plan quantity.
The approach to this scope has been to preserve enough existing material
in place to pave on existing material to meet the new elevations of the
precast box and roadway curb and gutter. The volumes have been
calculated based on existing surface and proposed surface elevations,
resulting in a net volume of asphalt material to be removed through the
milling process.
2. Nuisance flows
a. Nuisance flows from storm events could occur as upstream storm water
collection points will not prohibit entry of water into the Arthur Ditch. As
storm events are unpredictable in their frequency and volume, the
occurrence of such an event(s) and their run-off are incidental to the work.
3. Cast-in-place precast lid
a. A precast lid for the transitions pieces associated with the two end
connections would be considered, however the transition pieces are
anticipated to transition both horizontally and vertically, thus requiring the
top or lid component to be provided with exact shop drawing
specifications, possibly after the completion of the as-built wall segments.
4. Existing Parking lot conditions / staging area
a. All conditions will be assessed prior to mobilization. If damage does incur
and repair is needed, the awarded contractor will make repairs at the
contract price. The estimate quantity has been increased through
addendum 1 to include an additional 85 tons of material based on a
150’x30’ area, quantifying a reasonable worst case scenario.
