City of Centervllfe PeltIer Lake Or. Area Street & Utility Imp. Pagel 8/11/09 Claim #3 (Work Order No. 4222) In summary, the claim is for additional time and materials needed to complete the sewer repair at and adjacent to MH 210A due to the presence of a sanitary sewer forcemain which was shown on the drawings as being on the opposite side of said manhole. The forcemain made excavation and backfill of the sewer more difficult and time-consuming. City records showed the existing forcemaln to be on the west side of the sanitary manhole to which we were to reconnect with the re-laid sewer. However, upon excavation of the area, it was discovered that the forcemain was actually on the east side of the manhole, putting it In the way of the sewer installation. Working around this forcemaln represents a change In conditions and justifies the extra costs requested by this claim. However, the connection made to the sanitary sewer manhole at this location was not core-cut. Therefore, the cost of the core-cut and rubber boot should be deducted from this claim. Based on the bid price for a connection to an existing manhole, we have estimated the cost of the deduct to be $600. Claim #4 (Work Order No. 4560) In summary, the claim is for additionai time and materials needed to re-Iay storm sewer pipe after encountering a connict with the depth of the existing sanitary sewer force main. Again, because of the lack of proper records of the exact location and elevation of the forcemaln in this area, a connict with the storm sewer grade arose. In onder avoid the connict, several lengths of pipe had to be reinstalled. This unforeseen condition justifies this claim. Claim #5 (Work Order No. 4802) In summary, the claim is for additional time spent by your crew while waiting to retrieve different sized pipe than called for by the plan. As with any work, existing conditions affecting the contractor's progress need to be checked by your crews prior to beginning work. Additionally, if work is interrupted to retrieve materials not immediately available, we expect that your crews would be kept busy doing something else on the project as long as there still remains significant work left on the project. Therefore, this claim is denied. The following is a summary of the Claims addressed herein. Claim Number Claim # 1 Claim #2 Claim #3 Claim #4 Claim #5 Total Claim Amount $3,992.00 $381.57 $3,004.26 $2,699.00 $803.59 $10,850.42 ADDroved Amount $3,992.00 $381.57 $2,404.26 $2,699.00 $0.00 $9,476.83 If both parties (contractor and owner) are agreeable to the terms of the Engineer's review of the claims as detailed above, we will draft and process a formal change order to incorporate this work into the contract. 1_
