Review of Payment Application#10 8 March 2013 Page 3 �- Further, Comanco has requested payment for the following change orders: CR 1026 Electrical Work: 67% of $23,967 = $16,057.89. Comanco is requesting payment for the remaining 67% of the amount for this item. The work for this change order was triggered by the absence of an electrical connection on south of the site access road. Geosyntec had assessed an existing electrical connection at the old flare location. However, this connection was already removed during the flare relocation project in Spring 2012. This change order was issued to account for surveying by electrical subcontractor, 2 directional borings for the electrical and telephone lines under the site access road and work associated with running electrical conduits from the cell control panel to the flare station control panel. The work for this change order has been completed. Geosyntec considers this change order reasonable and recommends for approval. The reviewed change order request is included as an attachment to this invoice review. The work for this Change Order is complete.

The change order is based on quantity adjustments as described above for the respective line items. Geosyntec considers this change order reasonable and recommends for approval. The reviewed change order request is included as an attachment to this invoice review. The work for this Change Order is complete. CREDIT ISSUED TO THE COUNTY The original contract amount for the project was $3,247,500. This amount was calculated based on the estimated material quantities on the bid form and their corresponding unit prices. However, the actual quantities for several line items based on surveying by Comanco were either higher than or lower than those estimated on the bid form. For the items with the actual quantities based on surveying lower than those estimated on the bid form, Comanco issued a credit to the County. The credit issued to the County reflects the overestimation of quantities on the bid form. Based on summation of the amounts for the overestimated items, the total amount credited to the County as a part of this invoice was $91,851.09. With addition of the previously issued credit of$3,300.00, the total credit to date issued to the County was $95,151.09. RECOMMENDATION FOR PAYMENT Therefore, taking into account the pay items and the change order, the total invoice amount to date is $3,497,265.42, which is 100 percent of the project total contract amount of $3,497,265.42.
