This is also the last Change Order, except for a "balancing" Change Order which recognizes the differences in bid quantities from field quantities.

E: ,~;., ',f',J rJ i.'. ;.~.. ?_; -,,~ ",\; !o;]'''':_\ ~E, ~ ?, e e EXPLANATION OF NEED FOR CHANGE ORDER #11 Item #1. When DSRSD installed the water main in Dublin Blvd., they installed two laterals. It was assumed that one of the laterals was for the City's irrigation service. It turned out that both laterals were for private property and that a separate one needed to be added for the City's need. Item #2. One of the existing traffic signal pull boxes would have been located in the street pavement area after the widening of the intersection. The pull box needed to be relocated into the new sidewalk area prior to the pouring of sidewalk. Item #3. This item included some broken sidewalk, as well as the need to relocate the handicap ramp at the northwest corner of Dougherty Road and Dublin Blvd. The ramp needed to be moved to match the new striping plan. Item #4. Afield staking error of a median island on Dublin Blvd. near the Southern Pacific right-of-way required additional base rock to be brought in and regraded and compacted. This is to be reimbursed by the consulting engineer who field staked the work. Item #5. Mr. John Moore had contracted with PG&E to add underground conduit to his Tract 5900 site after the ci ty proj ect was awarded. This required some of the curb, gutter and sidewalk to be split into two concrete pour operations. The extra cost in this item is offset by the deletion of sidewalk along the Moore property frontage. The cost of this item is paid for as part of the assessments to the Moore property. Item #6. Two of the traffic signal loops were cut and needed to be replaced when a survey monument was drilled into an area where loops were previously placed. The loops were not visible as they were set into a lower course of asphalt. Item #7. The plans called for the irrigation controller service to be provided "by others," presumably by PG&E. As the street lighting system will belong to the City, PG&E would not do the work, requiring the City to run this service. Item #8. A driveway depression was inadvertently directed by the City not to be put in when the sidewalk was eliminated along the John Moore property. This item replaces the curb and gutter with a driveway approach. EJrI~i ~~if !; ,~, :tl ~ ~ ;J 3.
