The additional cost related to this change is $55,819.50.
Communication Conduit: Conduit for the communication lines will also need to be installed across the entire width of Doak Boulevard in order to provide service to the facility. This change will coincide with the above mentioned gas conduit change. The additional cost related to this change is $15,147.
The additional work is to be billed at a cost not to exceed $70,966.50 FISCAL IMPACT:
