The increase in the amount of actual bid items constructed over the original bid amount
resulted from the need for construction of additional Concrete drive approaches, curb
and gutter, and sidewalks. The final overall construction cost including change orders
was 9.89 percent over the original bid amount.
A total of three change orders totaling $58,933.20 were issued to complete the project.
They were as follows:
1. A change order in the amount of $11,400.00 provided for the initial revised
alignment and for increased valve costs.
2. A change order in the amount of $5,000.00 provided for the boring across
Dover Drive.
3. A change order in the amount of $42,533.26 provided for pipe alignment
revisions, additional fittings, vault connection revisions and an added 6 -inch fire
