Approve Change Order #1, Pine Bend Trail Improvements, Project � _� � ITEM # �. � *�x***�r**�r************�*********�r***MEMO********�****************�r***�****** DATE: JUNE 28, 1990 TO: MAYOR & COUNCILMEMBERS C/O CTTY ADMINISTRATOR JILK FROM: CITY ENGINEER/PUBLIC WORKS DIRECTOR HEF RE: ITEM FOR THE JULY 3, 1990 COUNCIL MEETING CUN3ENT AGENDA Approve Chanae Order #1 to Contract 1990-1, Pine Bend Trail Street Recanstruction This item consist of Council approving the attached change order and authorizing the Mayor and City C1erk to sign it. This memo provides the background information as to the necessity for the change order and a recommended action for Council to take. As Council may recall, we discussed this matter when we had the public hearing on Pine Bend Trail Street Reconstructian on June 5, 1990. The original change order we were talking about would reduce the amount of patching and craek sealing to bring the contract amount from $275, 000 to about $183, 000. Since that time we have met with the Contractor, Ace Blacktop, Inc. , and he has proposed that we grind up the existing pavement in place and cover it with 2" of blacktop and then a 2" blacktop surface coarse. We have just received a price from the Contractor that is a little over $199, 000. The price for grinding up the pavement in place and overlaying it with 4" of blacktop is about $16,000 more than patching, crack sealing and overlaying the existing roadway. Actually, the grinding option will give us a better roadway than had we gone with the original contract and cut out most if not all of the bad pavement. Therefore we actually are saving almost $76,000 under this option and, in my opinion, not sacrificing the intent of the praject at all. Although the original proposal reduces the amount of patching and crack sealing would have given a satisfactory result, we undoubtedly would have been out crack sealing much sooner and sealing many more cracks than we would be if we grind up the pavement in place and place the 4" of new blacktop on top of it. Grinding pavement is not new as it has been used for recycling purposes for several years. However this procedure of grinding the materials in place, compacting then overlaying it with new blacktop is rather unique. It is- started to become more prevalent recently and Ace Blacktop, Inc. has done some work around the Metro area regarding this option. Most of the work has been more related to parking lot reconstruction, but both our consulting . ,�� , engineers and myself feel that it would be a good application for this project. The additional $16, 000 will not pose any problems because we advertised that the project cost at the public hearing would be $330, OOD. That was based on the original bid of $275, 000 plus some contingencies. Under the 1989 plan, the City's share would have been about $39, . 000. We estimate it would be about $20,000 for the Citys' share under this scenario. Recommended action for Council to consider is to approve the Change Order #1 to Contract 1990-1, Pine Bend Trail Street Reconstruction resulting in a revised contract price of $199,479. 88. :y � -�� . . � . =� CHANGE DRDER �� ENCINEERS�ARCHlTECTS�PLANNERS 3535�ADNAISCENTERORN�Sf.PAU4 MlNNF.5f7fA55110 612 490-2000 City of Rosemount June 22 , 1990 OWNER L14TE 199 1 OWNERS PROJECT NO.
