Site work and paving for a sidewalk / parking lot in Mason, Michigan. Completed plans call for site work for a sidewalk / parking lot; and for paving for a sidewalk / parking lot.

Request for a proposal to reconstruct the East Car Parking Lots at the North Aurelius Elementary School, 115 N Aurelius Road , Mason, MI 48854 and Alaiedon Elementary School, 1723 Okemos Road, Mason, MI 48854. It is the intent of this project to cold mill the existing asphalt pavement, and aggregate base, to a depth sufficient to allow the placement of five inches of new asphalt in the East Car Parking Lot, as indicated on the enclosed satellite image. The existing asphalt pavement is on a good quality aggregate base. Once the above work is completed, the contractor will proof roll the aggregate base with a loaded truck, which meets the approval of the engineer, to determine if there are any soft or unstable areas. If any of these conditions are encountered, the contractor will do subgrade undercutting, type IV as indicated by the engineer. In these undercut areas, drainable fill shall be used up to the bottom of the existing aggregate base. Aggregate base required to complete the undercut areas shall be acceptable to the engineer. This item shall be included by the cubic yard. Four-inch, geotextile wrapped, underdrains shall be installed as directed, bedded in pea stone, and connected to the existing drainage structures. The actual placement of these underdrains will be determined in the field, by the engineer, and the costs associated with tapping into these structures, as well as costs associated with the removal of excavated spoils, shall be incidental to the under drain pay item. capable of sprinkling the grade, and maintaining the moisture content of the aggregate base to within two percent on either side of the optimum moisture content. The costs associated with this shall be incidental to other items. Curb and gutter shall be removed and replaced, as directed to match the existing. Drainage structures shall be adjusted as directed, with the intent of salvaging and re-utilizing the existing cast iron frames and grates. Once the preceding work has been completed, asphalt pavement will be placed. The new asphalt pavement shall consist of three- and one-half inches of 3C Modified base course, apply a bond coat (SS-1H), followed by one- and one-half inches of 5C Modified surface course. Minimum traffic control shall provide for safe ingress and egress, and protection of residents, staff, faculty parents, students, and emergency vehicles, from the construction operation. A traffic control plan provided by the contractor shall be approved by the engineer. Temporary ramps, as required, shall be incidental to other work items. All materials not incorporated into the work will be removed from the site; any areas that are disturbed by the construction will be repaired to a "like" condition.
