See Attachment "B" for itemization of additional labor and parts. Justification for Change in Contract See Attachment "A". Cost Reconciliation See Attachments "A & B". Construction Contract Accounting Summary Original Contract Amount: Net change by previously authorized Change Orders: Contract amount prior to this Change Order: Amount of this change order: New contract amount: Original contract time (calendar days): 120 Previously approved additional working days: 0 Additional working days for this change order: 0 Total contract time (working days): 120 (see Weekly Statement of Working Days for completion date) Reviewed by: Principal Civil Engineer Date Agreed to and Accepted by: 03/11/10 Koch strong Date al Fng., Inc. cc: Contractor, Construction File, Project Manager, City Clerk 1,916,282.35 3,785.67 1,920,068.02 4,740.75 $ 1, 924, 808.77 Recommended for approval by: 1243 National City Boulevard National City , CA 91950 Tel (619) 336-4380 Fax (619) 336-4397 CITY OF NATIONAL CITY Marina Gateway Streetscape Specification No. 08-16 ATTACHMENT "A" CO #2 Justification for Change in Contract This change in contract is due to the existing conditions and types of connections required for the new water line being different than the conditions shown on the plans at Bay Marina Drive and Marina Way and for Cleveland Avenue and 23rd Street. The Bay Marina Drive connection is into a steel line which requires welding and a butt strap not originally anticipated in the bid documents. The Cleveland Avenue and 23rd Street location will require a wet tap by removing an old service line at the connection point. Both locations will require a water line shut down for the wet tapping. Since this line services the hotel and there is no other way of high lining the hotel the work must be done at night. The new process not originally considered in the bid documents will require the additional services of a welder, extra parts and four (4) hours extra crew time, as itemized on Attachment "B". This change in contract is necessary because the conditions making this work necessary were not shown on the bid documents and constitutes a changed condition. This change order is also necessary to prevent further delay of this project and to provide adequate notice to local businesses that will have their water temporarily disabled while the work is performed. The work for this change order will be performed by Charles King Company, a contractor experienced with and qualified to perform such work and subcontractor to the prime, Koch -Armstrong. Cost Reconciliation This change in the contract was reviewed and negotiated by and between the City Representatives and the Contractor and represents the entire agreement for the work described herein and includes all costs associated with the work including but not limited to manpower, equipment, labor, fees, taxes, insurance, bonding, overhead, profit, etc. and there will be no other compensation. This Change Order hereby incorporates the original contract and all its referenced documents' terms, conditions, and plans for the work as provided by the City.
