Adjustment of horizontal survey control due to inaccurate coordinates provided on the construction plans. $ 868.14 2. The final connection point was relocated to reflect the actual location of the tie-in point of the existing 16"waterline in Valle Vista Drive. This required the addition of two(2)45 degree bends,thrust blocks and pavement repair. $ 1,126.29 3, Remove and dispose of excessive dirt from a 4-foot high embankment on the east side of Country Club Drive,approximately 100 feet south of Valle Vista to facilitate the installation of a new fire hydrant. $ 593.67 4.

Many of the existing water services in Country Club Drive and Los Serranos meandered between the water meter and main line.

This cost covers the additional staff and equipment time incurred during the decreased production period. $ 8,253.42 6. The 8"waterline in Los Serranos had to be realigned due to conflict with the existing parallel 8" waterline which was found to be in a location inconsistent with the record drawings. This required additional pipe,fittings,and trench repair. $ 6,228.45 7.
