This document is Change Order Number 03 for DEP Contract No. EXC018, issued on 08/18/2015, between the Florida Department of Environmental Protection (DEP) and Layne Christensen Company, located at 5061 Luckett Rd., Ft. Myers, Florida. The change order involves the Collier-Hogan DWM-2 project, with Christopher Bannon representing the contractor and William Martin serving as the DEP Contract Manager.

The change order modifies the original contract due to challenging drilling conditions at an approximate depth of 1530' BLS, which required significantly more drill rig time, materials, and additional operations. Key modifications include revisions to the Scope of Work for well development procedures, installation of a 6-inch diameter production casing, and wellhead configuration. The contract involves drilling, casing, and groundwater sampling activities, with provisions for a 30-ton crane and crew to assist in well development. The total contract cost increased to $1,473,328.80, with no change to the original contract completion date of 10/27/2015. Exhibit A-1 attachments detail wellhead specifications, including a 34-inch diameter steel pipe enclosure with a hinged lid and provisions for secure access and sampling.
