Home My WebLink About7 Donner Park Pipeline Crossing TDPUD MEMORANDUM December 12, 2001 TO: Board of Directors FROM: Neil Kaufman, Water System Engineer SUBJECT: DONNER PARK PIPELINE CROSSING MODIFICATION CHANGE ORDER #1 AGENDA # BACKGROUND: The Board of Directors previously awarded the Contract for construction of the Donner Park Pipeline Crossing Modification project to Contri Construction. The project has been completed. I am requesting a Change Order to the Contract for issues covered under five general items. Item 1 : The contract was originally written based on a 90 percent compaction requirement for the backfill of the slope excavation. The Encroachment Permit application filed with Caltrans indicated this 90 percent requirement. At the pre-construction meeting, the Resident Inspector for Caltrans indicated a 95 percent compaction requirement. The contractor (and the District) had originally intended to use screened native material for the excavation for the backfill. However, 95 percent compaction could not be achieved using the native material. Therefore, it became necessary to export and dispose of the excavated material from the site, and to import new material that would meet the 95 percent compaction requirement. Contri Construction is due $28,865.64 for this change. This covers dump fees for the excavated material, purchase of the new material and trucking involved in transporting the material. Item 2: The Bid Documents indicated that the total length of water pipe and casing pipe was 40 feet. Upon completion of the initial excavation, it was determined that the overall length was 50 feet. Contri Construction is due $6,677 to cover the purchase of an additional 10 feet of water pipe and casing pipe. Item 3: The Bid Documents indicated that the total height of the vertical manhole was 32 feet. Upon completion of the initial excavation, it was determined that an additional two feet should be added to the manhole height. Contri Page 1 Construction is due $329.48 to cover the purchase of an additional 5'd x 2'h manhole barrel. Item 4: As noted above, an additional 10 feet of casing and water pipe was installed. Most of this length was necessary to repair damage caused to the casing caused by installation of the fiber optic conduits. This additional length required that the casing and water pipe be extended out into the pavement section and necessitated the removal and replacement of some pavement. The original Contract Documents did not call for any pavement disturbance and Contri Construction owed $588.10 for pavement restoration. Item 5: The Contract Documents called for protecting the lower part of the restored slope with a layer of shotcrete, and then reseeding the upper portion of the slope. The Contractor placed the shotcrete, but was unable to perform the reseeding prior to the first snowfalls. The District is receiving a$2000 credit for work not performed, and will hire a separate landscape contractor to complete the slope restoration in the Spring. RECOMMENDATION: I recommend that the Board authorize Contract Change Order #1 , in the amount of a $34,460.22 payment to Contri Construction.
