All work,materials, and measurements to be in accordance with the provisions of the Standard Specifications and
Special Provisions for the type of construction involved.
THE CONTRACT IS MODIFIED AS FOLLOWS:
Background:
Issue#1
The City determined that a temporary signal system will be needed to control traffic operations of the high traffic
volume intersection of Pines and Mission during the traffic control phases(1 and 2A). The planned modifications
to the existing signal system will require the existing signal to be non-operational for several weeks until the new
signal modifications are installed,and the signal can be re-energized.
Issue#2
City determined potholing existing utilities in advance of the Contractor's installation of storm pipe P3 will reduce
the risk of utility conflicts during its installation at a later phase of the project.
Description of Change:
Issue#1
This change order compensates the Contractor for providing,installing,maintaining, and removing a temporary
signal system for the intersection that accommodates the traffic lane configurations for both traffic control phase 1
and 2A.
Issue#2
This change order compensates the Contractor for potholing existing utilities on the south side of Mission Avenue
(Sta 5+40 to 5+60 Rt), at the locations shown below plus one additional pothole for the recently found duct bank:
