| SUBJECT: |
| Council Consideration of a Change Order for Interim Final Quantities Adjustments for the Gillette Madison Pipeline Project, Contract 2a with Layne Christensen Company, in the Amount of $633,385.81. |
| BACKGROUND: |
The construction contract for Contract #2a will include the drilling of three new wells into the Madison aquifer. The majority of the drilling operations were completed in October, 2017, but the project has been on hold while the State of Wyoming Department of Environmental Quality (WDEQ) completed an investigation for groundwater quality and level impacts in the surrounding area.
Change Order 07 is an interim final quantities adjustments change order for items in the project that are complete. The majority of the overruns occurred on wells M-14 and M-15 during the casing and cementing operations. |
| ACTUAL COST VS. BUDGET: |
The original contract amount for this project was $14,027,028.00. There are six change orders prior to Change Order 07 for a net added cost to the project of $1,125,696.06. Below is a summary of these change orders:
