The Hester's Crossing Channel Improvements project includes the construction of two rock
gabion walls with mortared rock rip rap in between both walls. The site is located
downstream of La Frontera Village am which is north of Hester's Crossing Road. During
excavation of the site, the contractor had issues with constant ground water coming from
underneath the existing road culverts and below the ground. After excavating to the
proposed grades for installation of the mortared rock riprap, a constant supply of ground
water was found.
The engineer of record was informed via a Request for Information and asked to provide a
recommendation for properly routing the ground water downstream. A french drain
composed of nine inches of bedding rock was recommended and was installed to deal with
the ground water between the walls.
The contractor was instructed to install nine inches of bedding rock with filter fabric in
between the walls. Change Order No. 1 include the cost of labor, additional materials and
equipment for the work performed. Total cost is $3,253.61
Cost: $3,253.61
