Wasden, Inc. for storm drain improvements in "E" Street from 4'h Street to 5'" Street and pavement rehabilitation from 4'" Street to 6'" Street. Backl!round: On May 15, 2000, the Mayor and Common Council awarded a contract to David T. Wasden, Inc. in the amount of $178,798.50 for storm drain improvements in "E" Street from 4'" Street to 5'" Street and pavement rehabilitation from 4'" Street to 6'" Street. During construction, subsurface conditions were encountered which were significantly different from the conditions shown on the plans. Under Section 3-4 "Changed Conditions" of the Standard Specifications, the contractor is allowed to recover additional costs due to "subsurface or latent physical conditions differing materially from those represented in the contract. " The changes are described as follows: Description of Change Cost Item 1: Additional pot holing on October 16, 2000, to locate Southern California Edison conduit, General Telephone conduit and a gas line in 5th Street that were not shown on plans. Also, $2,813.66 additional investigative pot holing of new tie-in location on "E" Street as directed bv the Endneer. Item 2: Additional pot-holing on October 17, 2000, to investigate $1,560.23 Pacific Bell conduit bank at the proposed new tie-in location. Item 3: Additional pot holing of sewer main and fiber optics duct cluster in "E" Street on October 18, 2000. $2,186.98 Item 4: Delay cost due to breakage of unmarked water line at Station 21 +00 in "E" Street on October 19, 2000. $ 891.47 TOTAL CHANGE ORDER COST $7,452.34 () (J~ i;:-jr1!;~ r-~"oU .\ YL).11c1 1J./'i-ltfO JUSTIFICATION: ITEM 1: 1. A bank of General Telephone conduit, a bank of Southern California Edison conduit, and a Southern California Gas line, which were not shown on plans, were found to exist on the north side of 5" Street. These existing utilities were found as a result of the Underground Service Alert (USA) call-out. The contract specification requires the contractor to pothole utilities shown on plans; however, these utilities were not identified on plans and had to be pot holed as a change order. It was essential that the contractor pothole these utilities prior to start of pipe laying to insure there would be no conflict with the proposed storm drain. 2. While excavating for the outlet into a catch basin on the west side of "E" Street immediately north of 4" Street, it was discovered that a bank of Pacific Bell Telephone conduits would conflict with the proposed alignment of the storm drain. There was no way to clear the telephone conduits so the connection point was moved to a deeper catch basin immediately downstream. In order to assure that the storm drain could be installed under the conduit bank it was necessary to pothole the conduit so that sufficient clearance could be confirmed. It was determined that clearance was inadequate for the specified 24-inch diameter reinforced concrete pipe (RCP); however, sufficient clearance was available for two 18-inch diameter pipes. Therefore, the contractor was directed to substitute two 18- inch diameter pipes in place of one 24-inch pipe. ITEM 2: This was a continuation, on October 17, 2000, of the pot holing started on October 16, 2000. The additional pot holing was necessary to fully expose the conduit banks so that City Surveyors could measure the available clearance for the proposed storm drainpipe. ITEM 3: After start up of construction, it was determined that a cluster of fiber optic ducts crossing at Station 15+03 in "E" Street would conflict with the proposed location of the storm drain. It was necessary to have the contractor perform pot holing of the cluster of fiber optics ducts and a sewer main at Station 11 + 95 to provide survey data needed to re-design the storm drain grade so as to clear the sewer and the cluster of fiber optic ducts. The pot holing was performed on a Time and Material basis in accordance with Section 3-3 "Extra Work" of the Standard Specifications. ITEM 4: While excavating for the 24-inch storm drain in "E" Street at approximate Station 21 +00, the contractor broke a 'j,-inch diameter water line that was not marked in the field or shown on plans. The line was abandoned but was still live where it crossed the contractor's trench. Consequently, the contractor's excavation was flooded and the storm drainpipe, which had been mortared a few hours earlier, was flooded, damaging the mortar. The contractor had to muck out the trench so that a Water Department crew could repair the broken line. The contractor also had to re-mortar the pipe joints. Additional time to complete Contract due to Change Order--O Workinl! Davs All work on this project was completed and accepted on November 17, 2000. Although not yet finalized, we anticipate a second and final change order which, together with Change Order No. One, will result in a net increase in the contract of approximately $33,000, which takes into account credit for items which were reduced in quantity or deleted entirely. The additional costs associated with the up coming change order are primarily related to greater depths in the storm drain and structures than envisioned due to conflicts with existing utility lines that were prohibitively expensive to relocate. This amount will likely exceed the approved contingency amount of $26,881.50. We anticipate bringing Change Order No. Two before the City Council at its meeting of 12/18/2000. Approval of Change Order No. One will allow timely payment to the contractor for additional work above and beyond the requirements of the original contract which resulted from changed conditions at the job site. Despite the changed condition, the contractor, working with Public Works staff, was able to complete the project on the accelerated schedule prior to the holidays. Financial ImDact: Sufficient funds are available for this change order from the amount originally authorized in Account Nos. 248-368-5504-7207 (Storm drain improvements at "E" Street - $149,105), 129- 367-5504-7192 (Pavement rehab at "E" Street - $50,000), and CDBG 99-0039 (Street resurfacing downtown $51,395). Recommendation: That the Mayor and Common Council authorize execution of Change Order No. One, in the amount of $7,452.34, to contract with David T. Wasden, Inc. for storm drain improvements in "E" Street from 4" Street to 5" Street and pavement rehabilitation from 4" Street to 6" Street. DAVID T. WASDEN.
