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 dam 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 gabion walls foundation base, the contractor did not find stable material at this
elevation.
The engineer of record was informed via a Request for Information and asked to provide a
recommendation for an alternative foundation design. After analyzing the site, it was
determined that each of the foundations would need to be over excavated to a depth where
stable material was found.
The contractor was instructed to over excavate the site, backfill and install a rock foundation
as the base for each of the gabion walls. Change Order No. 2 include the cost of labor,
additional materials and equipment for the work performed. Total cost is $12,485.25
Cost. $12,485.25
Source of Funds: 2014 Drainage Revenue Bonds
