Okaloosa County BOCC — December 16, 2014 — Action Item Printout

BOARD OF COUNTY COMMISSIONERS AGENDA REQUEST DATE: December 16, 2014 TO: Honorable Chairman and Members of the Board FROM: Jeff Littrell SUBJECT: Layne Christensen Company Change Order #5 for Del Cerro II Well DEPARTMENT: Water and Sewer BCC DISTRICT: 1 STATEMENT OF ISSUE: Approve Change Order #5 of Layne Christensen Company, Inc.’s Contract # C13-2026-WS, which would add additional scope of work to the construction of the Del Cerro II Public Water Supply Well. BACKGROUND: Okaloosa County entered into contract with Layne Christensen Co., Inc. on April 3, 2013 for the construction of the Del Cerro II Public Water Supply Well in the amount of $934,895. Due to unforeseen site conditions, four (4) change orders have been executed on this contract to date, which now make the total contract amount $1,065,805, with a final completion date of December 11, 2014. The change orders stem from the water bearing formation exhibiting a lower yield and sand. The change orders can generally be described as follows: 1) extended test pumping, 2) surface casing issues, 3) gravel pack (filter) and screen installation, and 4) pump discharge column size and building modifications. The project is now on track and the well itself below ground has been completed. With the additional work authorized by the change orders mentioned above, the yield and sand issues have been remedied. The contractor is now working on finishing out the well building. In the process of constructing the building, several delays have occurred because of longer than anticipated delivery times and more complicated submittal reviews (because of the building being modified). OCWS staff and engineers have reviewed the request for a 55-day extension, and we believe it is fair and reasonable. The new final completion date will be February 4, 2015. OPTIONS: Approve or deny. RECOMMENDATION: OCWS requests BCC approval to authorize the Chairman to execute Change Order #5 with Layne Christensen Company on Contract #C13-2026-WS for the Del Cerro II Public Water Supply Well, which adds 55 days to both the Substantial Completion and Final Completion dates.
