DS 270000000004 SCHEDULE B - PRICING MATRIX Columbus Oil Project.xlsx

This is a pricing matrix for the Columbus Oil Orphan Well Plugging Project in Cass County, Michigan, administered by the Michigan Department of Environment, Great Lakes, and Energy (EGLE). The project involves plugging 22 wells and requires bidders to submit detailed unit pricing for all line items listed in the matrix, regardless of anticipated use. The pricing matrix encompasses a comprehensive range of services and materials including contractor supervision, labor, equipment rental (rigs, pumps, tanks, heavy machinery), wellhead equipment (casing, tubing, drill bits, bridge plugs), drilling fluids and additives, cementing services, wireline services, waste disposal, and transportation services. Bidders must provide quantity estimates and unit pricing for each item, submit a project timeline assuming 10-hour workdays, and obtain EGLE Project Manager approval before mobilizing, using, or charging for any items not pre-approved or for specialized equipment and supplies.

Pricing for all line items is submitted at zero dollars pending bidder proposal; bidders must provide actual unit prices for each listed service and material. An overhead percentage may be applied only to materials or services not already included in Schedule B line items and specifically not to hourly or daily rates already listed. Additional line items may be added to the pricing matrix if necessary materials are required for proper well plugging. Key restrictions include limiting invoicing to one Contractor Site Supervisor per day unless authorized otherwise, prohibiting double-billing when rig crews perform general labor duties, and requiring prior approval for any rental, purchase, or deployment of specialized equipment. All pricing submissions must account for potential scope changes, change orders, or conversion to time-and-materials billing, with the matrix serving as the baseline rate structure for project invoicing.
