CHANGE ORDER #9 April 13, 2010 Project: Marina Gateway Streetscape Specification #08-16 Contractor: Koch -Armstrong A Change Order is hereby recommended for the following work in the amount identified below: Description of Change in the Contract This change in contract is for repair of a damaged electrical service conduit on the east side of 23rd Street between Harrison Avenue and Cleveland Avenue. Justification for Change in Contract This change in contract is necessary because the vertical alignment of the sewer main was lowered in this area to increase and improve the flow characteristics of the main. In the previous 20B electrical conversion some of the conduits crossing the sewer main went below the the main. The new sewer main location is into the electrical conduits. This requires the electical conduits to be lowered as well. This change order pays for the removal and replacement of the conduits in existing slurry to be relocated below the new sewer main Cost Reconciliation See Attachments "A & 8".

CTB is a rigid base materials that can withstand water infiltration. As a result of a design change to add a 12" deep concrete curb around the pervious paving the Engineer determined that the use of CTB is no longer warranted. CTB can now be substituted for the less expensive Crushed Miscellaneous Base (CMB) and still be within design criteria. This will represent a significant cost savings to the project. CHANGE ORDER No. 10 May 25, 2010 I The City of National City and Contractor agree to the following change to the original Contract: lContractor shall replace Cement Treated Base with Crushed Miscellaneous Base for each line item that calls for lCTB as the base material, including but not limited to Line Items #19 and #20.
