24th STREET COMMUNITY GATEWAY
CIP NO. 17-21
Contractor: LB Civil
CHANGE ORDER NO. 1
March 12, 2018
Reason/Purpose for this Change Order:
A design change for the Community Gateway Sign located at 24th Street and Wilson Street was required due to
an unforeseen site condition. During a site inspection, it was observed that the foundation for the proposed
gateway sign was directly on top of a culvert. The original design of the gateway was modified to assure that the
load restriction due to site conditions were met. The new design (see attached) shows a layered wall installed on
the top of the redesigned concrete pedestal.
The City of National City and Contractor agree to the following change to the original Contract:
The City and the Contractor agree that the Contractor shall proceed with with the fabrication and installation of
the wall fixture on the concrete pedestal (per the attached drawing). The wall material will be a 3/8" thick steel
welded to a 3/8" x 4' wide x12' long base plate bolted to the concrete pedestal. The agreed upon price for all
costs associated with this work is a total of $9,987.00.
