justification
rhis is a quantity adjustment for bid items No. 510 "Pipe, 8-in. Dia. SDR 26 PVC (all depths), including Excavation and Backfill", No. 594
'Gabions", and No. 594 "Revet Mattresses". When the pipe was excavated it was found to be in good condition and have no need to be replaced,
=rosion concerns were brought up in an area with two small outfalls. Adding a revet mattress would alleviate these concerns. During
:onstruction, a section of gabions was found to be failing so the project limits were extended to include them.

The Hesters Crossing Downstream Channel Improvements project is located south of Old West
Drive, behind the Learning Tree Day School. The project involves repairing structures within the
channel to resolve erosion issues. Existing gabions that are failing will be replaced. Rock
riprap, mortared and dry, will be installed at the bottom and behind the channel to help stabilize
the channel.
Quantity Adjustment/Change Order No. 1 includes the cost of another revet mattress and
additional gabions. In the area where the gabions are going to be placed, there are two small
storm water outfalls that could cause additional erosion to the area. The placement of the revet
mattress would help in preventing erosion, and the additional gabions are to replace a section
of existing gabions that appear to be failing.
Quantity Adjustment/Change Order No. 1 is for $10,499. This includes the cost of labor,
additional materials, and equipment for the work. The contract amount will be adjusted to
$170,076.
Cost: $10,499
Source of Funds: 2014 Drainage Revenue Bonds
