Due to the street widening these facilities need to be <br />relocated, the contract documents call for relocation by others; after construction <br />started it was concluded that it would be more cost and time effective to have <br />them relocated under this contract. This cost includes: relocation of the metering <br />cabinet and vent stacks, installing concrete encased electrical conduits and vent <br />pipes, installing water metering and sump pump piping. Also included in the cost <br />is a new electrical service cabinet and wiring to separate MWD electrical power <br />supply from City power supply. <br />AGREED COST = $ 51 ,61 O <br />
