(CT &F). Under this contract, CT &F completed the construction task of second and third phases of the Traffic Signal Modernization Project.

A summary of the contract cost is as follows: Original bid amount: $520,299.47 Actual cost of bid items constructed: 519,708.10 Total change orders: 50,279.47 Final contract cost: $569,987.57 There were six change orders totaling $50,279.47. The change orders were for the following: Item No. Description Amount 1 Removal /reinstallation of additional traffic signal wiring, $ 1,237.21 upgrade pull boxes, and additional concrete work. 2 Replace damaged pull boxes, relocate water service, 8,458.21 conduit repair, relocate street light, abandon above round utility, and additional A.C. /concrete work 3 Relocate City conduit from AT &T vault, relocated pull 9,997.16 boxes, locate /replace damaged conduit. 4 Install additional 1,223 feet of new conduit and abandon 20,742.08 damaged conduit. 5 Modify traffic signal service, modify conduit, repair 4,041.86 damaged conduit, modify traffic signal foundation and install City- furnished traffic signal cabinet. 6 Replace malfunctioning EVP units (3 locations) and 5,802.95 asphalt/concrete repair. Total Project Change Orders $50,279.47 The change orders were result of finding additional damage to traffic signal equipment and conduit. Primarily, the change orders were related to in- ground damage or rotted conduit. Change Order 4 was significant at a cost of $20,742.08 and was related to two sections of rotted conduit which could not be reused. At the two locations, Bristol Street South between Campus Drive and Birch Street, and Jamboree Road at Ford Road, the underground conduit had degraded to the point where new traffic signal interconnect cable could not be installed in it. At these locations, new conduit was installed for a combined length of 1223 feet, and the damaged conduit was abandoned. Additionally, the Bristol Street South conduit replacement, as detailed above, also caused significant time delay to the project. The large number of underground utilities Traffic Signal Modernization Project Phases 2/3 — NOC — C -3976 April 13, 2010 Page 3 within the right -of -way forced staff to redesign the interconnect system, ultimately locating the new conduit in the dirt shoulder along Bristol Street North. The time needed to redesign the conduit run, along with the other change orders and extended equipment delivery times and caused a delay in completion of the project of approximately 59 days.
