Background Discussion

Change Order #1 increases the contract amount by $273,685.71 due to time and material required for revised water main construction to accommodate actual field conditions and for additional work identified during construction. This change order provides for additional cost and time associated with plan revisions due to the following items:

  1. Accommodate actual field conditions identified during construction. These actual conditions include the following: (a) Conflicts with other existing utility lines discovered during excavation, (b) modifying meter/service locations to disturb the least amount of homeowner's property, (c) plan revisions to proposed water main construction due to actual configuration of existing water mains discovered during excavation.
  2. Additional water services and meter relocations not identified on the original plans but found to be needed during construction.

Performing the additional work associated with the above requires an increase in the contract duration as requested by the Contractor.

Administrative Contract Adjustment #1, approved August 16, 2013, increased the contract amount by $64,566.06, from $1,749,148.93 to $1,813,714.99 and added 62 calendar days to the contract time. ACA #1 provided time and material for revised water main construction to accommodate actual field conditions and changed open cut construction to directional drill methods to minimize impacts to neighborhoods.

September 25, 2012, the BCC executed a contract with S.L. Williams Consulting Corporation in the amount of $1,749,148.93 for construction to replace approximately 16,100 linear feet of 6" diameter and 8,100 linear feet of 8" diameter potable water main along with approximately 400 services.
