Installation of the steel casing for this section of the project has been terminated at approximately station 11+93. This change order is to install new 36-inch CPEP pipe from CB-3 to a new catch basin that will be installed at the end of the casing (see figure). The change order includes all excavation, soil haul and disposal, shoring, bedding, new pipe, backfill, connection to catch basins, labor, equipment, and materials needed to install the new pipe. The cost per linear foot is based on the time and materials costs sheets attached to this change order.

Flaggers shall be used as needed to direct trucks and customers through the work area, and into and out of the car lot. The vehicle crossing at approx. station 11+60 shall be kept open to customer traffic as long as practical. When the crossing needs to be closed the dewatering system near CB-3 shall be removed and cones and signs shall be established to direct customers around that end of the construction area. On weekends (Fri, Sat, Sun) the construction area shall be plated and vehicles and material shall be moved to the storage/parking area on the east side of the property, per the Walker Property Temporary Phasing Plan drawing C5. Measurement for payment will be from center of structure to center of structure of installed pipe per Standard Specification 7-04.4. The actual length installed shall be determined by field measurement of the installed pipe. The unit contract price shall be full pay for all Work to complete the installation of the new pipe, including connection and adjustment of inverts to manholes and catch basins.
