Agenda Item

Consider approving Change Order No. 4 in the amount of $667,610.00 for BUS 79 Drainage, a Road Bond project in Precinct 4.

Background

Due to settlement issues of the railroad ballast, Union Pacific Railroad suspended the boring operations under the railroad tracks. The settlement was caused by boring through debris encountered during the Line F bore and the trestle bridge bent encountered during the first Culvert #1 bore. Union Pacific Railroad will require assurances that the procedures used for future installation will eliminate settlement issues prior to allowing work to resume. This change order compensates the contractor for additional work to purchase and install tunnel liner plates, to add grout between the liner plates and the RCP, and for daily grouting between the liner plates and the exposed earth (as opposed to grouting the whole line once the bore was completed).
