Under a separate contract with Garrett Construction Company, about 4 feet in depth of sand was removed and transported just south of this area and leveled. The location of the required work is at Padre island, Corpus Christi, Texas, at the north end of the seawall, in front of the El Constante Condominiums. The scope of this change order is to continue to transport sand from the same location towards lower areas to the south, but maintaining a leveled area in the north -south direction and with a gentle slope of approximately 1 on 12 towards the beach. The work can be done by maintainer (road grader), bull dozer, front -end loader or a combination thereof. The City surveyor will establish the high water line, marked with stakes and flagging. Before and after surveys will be performed for quality control and payment purposes. The limits of the work are from the seawall to the high -water line.An existing Corps of Engineers permit, dated December 5, 2008 exists which permits this activity. Prepared by ECMS LLC Feli H.

Please contact us with any questions or concerns at 361- 937 -9300. Sincerely, A�_ Ken R.

The change order includes additional stone, contract items F -1, F -2 and F -3. The contractor has proposed to perform the additional work at contract prices, as per contract requirements and requests an additional 45 days to complete the work. In view of the fact that this particular part of the contract was suspended until this change order is processed, it is equitable to grant the contractor the additional time requested. Regarding the sand removal; Item G -1, the contractor has proposed a price of $4.60 per cubic yard, The work has been discussed in the field with the Contractor and there is an understanding as to the scope of work. Based on the previous work performed by Garrett Construction Company, at $3.41 per cubic yard, and based on the fact that fuel prices have gone up considerably since then, it is my opinion that the price of $4.60 per cubic is a reasonable price. It is recommended that the contractor's proposal be accepted and the change order be issued. Feli H. Ocanas, Jr., P. . President, ECMS LLC PAGE 6 OF 6 PN 3400 CHANGE ORDER NO.1
