Home My WebLink About5 6160 Bridge Street Tank Change Order TDPUD MEMORANDUM August 16, 2002 TO: Board of Directors FROM: Neil Kaufman, Water System Engineer SUBJECT: BRIDGE STREET 6160 TANK CHANGE ORDER #1 AGENDA # BACKGROUND: The Board of Directors previously awarded the Contract for construction of the Bridge Street 6160 Tank to CB&I Water(CBI). CBI commenced work at the site on July 15, 2002. At that time, CBI began tree removal and processing and screening of the spoils materials located in the old Quarry site. After removal of the trees, CBI was unable to begin excavation of the storage tank pad since the Lahontan Regional Water Quality Control Board had not yet issued a Waiver of Waste Discharge. Upon completion of the tree removal and spoils processing, they began construction of the detention basin. Construction of the detention basin was not a critical path item, but it was the only remaining work that could be performed without the Waiver. The detention basin was completed on August 1 and CBI stopped work at that time since the Waiver of Waste Discharge still had not received by the District and there was no other work that could be performed without the Waiver. The Waiver of Waste Discharge was received on Friday, August 9 and CBI recommenced work on Monday, August 12. The critical path task for completion of the storage tank is the coating of the tank interior. Application of the coating is temperature sensitive and CBI had originally planned to begin coating the tank on September 18 as shown on the attached baseline schedule. In order to recover the lost time and ensure that the tank can be coated in September, CBI has developed a revised schedule based on working 12 hour days for 7 days a week. This revised schedule is also attached. This schedule will incur significant amounts of overtime charged for project labor. CBI has determined this additional cost to be $142,887.00. RECOMMENDATION: I recommend that the Board authorize Contract Change Order #1 in the amount of $142,887.00.

Means to make up time from the delay are as follows: We have based our overtime premiums on the site work on working 7-12 hour days, Sundays will be with a partial crew cutting slopes to minimize the double time required on Sundays and Holidays. We have included working 10 hours per day 5 days per week and have only included for time outside this time. We have based our overtime on piping on working 6-12 hour days,Monday to Saturday. We had based our original bid on working a 40-hour work week for the piping. We have based our overtime on the ring wall on working 7-12 hour days. We had based our original bid on working a 50-hour work week on the ring wall. We have not addressed the final grading and paving as it will depend on the availability of AC Concrete at the time work will be done. We have not allowed working on tabor Day as by Law we can only work this day in the case of an-targency. We will perform the tank erection with two crews and two superintendents working 4 days on 4days off alternating crews. We will be working 10 hour days. Overtime rates will be accounted for on Saturday and Sunday. Painting will be staffed in the same manner as the tank erection. It will be necessary for the tank and paint crews to be increase in size be 1 man each. Additional coordination will be required between RSH and CB✓?<I due to access and working in the same areas on the shortened schedule. The added cost to accelerate the schedule will be $142,887.00 Please give me a call if you have any questions.

This schedule does not take into consideration any unforeseen acts of nature such as rain, snow, or severe amounts of rock. The only additional costs that have not been addressed would be the additional trucking of AC if the AC: plant closes early. If for any reason the contract is pushed into next year, the cost of change order I will be deducted from the $200,000 associated with the accelerated bid schedule. The only additional money that would be expected is a negotiated portion of the difference of the $200,000 and change order No.1, approximately $ 57,000.
