DISCUSSION: HISTORY During the construction of Duluth Avenue, the Contractor, S.M. Hentges and Sons, encountered three situations that they felt were cause to request change orders in the original amount of $54,603.84 due to change in conditions or unforeseen circumstances. The City Council approved Change Order No. 1 in the amount of $17,517.00. The purpose of this agenda item is to amend Change Order No. 1 which the Council previously considered and approve Change Order NO.2, CURRENT CIRCUMSTANCES The Contractor has met with Engineering staff on two occasions since Change Order No. 1 was approved to discuss their request for the Council to reconsider Change Order No. 1 pertaining to the following items: 1. Additional work associated with modifications to a connection to a Metropolitan Council Environmental Services (MCES) manhole as directed by the MCES representative. In addition, subsurface conditions required unanticipated dewatering (Hentges change order reference #4). Original Contractor Request: $24,611.34 Amount Council Approved: $4,400.00 Amended Contractor Request: $22,611.34 2. Additional work associated with utility crossings under an existing telephone duct bank/fiber optic lines which is located along the east side of Duluth Avenue (Hentges change order reference #7). Original Contractor Request: $26,591.50 Amount Council Approved: $9,716.00 Amended Contractor Request: $22,316.50 16200~Creek Ave. S.E" Prior Lake, Minnesota 55372-1714 / Ph, (612) 447-4230 / Fax (612) 447-4245 AN EQUAL OPPORTUNITY EMPLOYER HENTC02,DOC ..,-> The above amended requests are dated December 28, 1998. Change Order No. 2 consists of requests for reimbursement for the following items: 1. The Contractor is requesting reimbursement of $627.83 for special signs that were requested for local businesses on Duluth Avenue. 2. The second request (Field Work Order #1) is for additional time and materials required to install watermain on Pleasant Street due to incorrect construction staking because of a plan omission. The Contractor has requested $1,412.50 for this item which includes 3 to 4 hours of crew time. 3. Additional work associated with replacing a cracked watermain tee on Birch Street. An additional payment of $499.43 is requested which includes 1.5 hours of crew time in addition to materials. CONCLUSION The Engineering Department staff has provided full-time inspection for the 1998 Improvement projects. Staff provided detailed recommendations for Change Order No. 1 with the November 2, 1998 City Council Report. Based on staff documentation of the construction and review of the Contractor's requests, the following is a summary of the recommendations: ChanQe Order NO.1 1. Change order reference #4 - The Contractor has submitted an explanation (attached memo dated December 28, 1998) for the request for additional work associated with the MCES manhole which states that if the additional excavation, dewatering, etc. would have been factored in the bid, the unit prices would have been higher to account for this. Staff feels that the specifications are quite clear with regard to subsurface conditions and dewatering, and does not recommend payment for dewatering items. The specifications contained soil borings for Duluth Avenue that show groundwater was encountered. Dewatering should have been anticipated based on the information provided. Additional time was required to install the pipe at a lower elevation than originally planned. Due to the fact that the contractor had an incorrect date on the original request and additional time was required, staff recommends payment of an additional $4,350.00 for 10 hours of additional time for work due to differing conditions in addition to the $4,400.00 which was already approved. 2. Change Order Reference #7 - The contractor had to hand dig around the telephone duct to install water services. Therefore, staff has reconsidered the original recommendation of 0.5 hours of additional time to install the services. If it takes approximately 1.5 hours to install a service on a typical project, the contractor would have been able to install 8 services in a 12 hour day. In reality, an average of 4 services were installed per day on Duluth, equating to 3 hours per service. The Contractor should be paid an additional two hours per service instead of half an hour. Staff recommends an additional $7,425.00 for the additional time required to install services. Cham:le Order NO.2 1. Payment of $627.83 for special signs. 2. Payment of $940.00 for extra work required to install watermain on Pleasant. This reflects a reduction to two hours of additional labor and equipment which was discussed by staff and the Contractor. 3. Payment of $82.50 for additional time required for the Contractor's foreman to obtain the necessary materials to replace a watermain tee. Again, this reduction was discussed by City staff and Contractor. The following table outlines the amount requested and the amount that staff is recommending for approval: Change Order No.1 Ref. # Amount Requested Amount previously Revised request Recommendation Total Staff approved Recommendation 4 $24,611.34 $4,400.00 $22,611.34 $4,350.00 $8,750.00 5 $3,401.00* $3,401.00 $3,401.00* $3,401.00 7 $26,591.50 $9,716.00 $22,316.50 $7,425.00 $17,141.00 Total $54,603.84 $17,517.00 $48,328.84 I $11,775.00 $29,292.00 *Removal of concrete cattle crossing. Change Order No.2 Item # Amount requested Staff recommendation 1 $627.83 $627.83 2 $1,412.50 $940.00 3 $499.43 $82.50 TOTAL $2,539.76 $1,650.33 Based on the fact that the projects are 95% complete, staff does not anticipate additional change order requests from the Contractor. In addition, it is staff's opinion that Change Order Requests No. 1 and 2 have been adequately discussed with the Contractor, adequately analyzed by staff, and staff will not bring these items back to Council for any further consideration. HENTC02.DOC FINANCIAL IMPACT: The original contract was $1,345,425.33. The Engineer's E3timate was $1,364,780.76. Revised Change Order NO.1 and Change Order NO.2 will increase the contract to $1,376,367.66 or less than 1 % above the Engineer's Estimate. Funding for this change order is proposed to be from the Trunk Reserve fund due to the fact the extra work was required in conjunction with the utility replacements. ALTERNATIVES: The alternatives are: 1. Approve revised Change Order No. 1 and Change Order No. 2. 2. Approve Change Order NO.2. 3. Deny this item for a specific reason and provide staff with direction. 4. Table this item until some date in the future. RECOMMENDED MOTION: A motion and second approving Revised Change Order NO.1 and Change Order NO.2 to the 1999 Improvement Projects, funded through the Tr k Reserve fund.

Fax 447-4263 FROM; Jim Kephart DATE:; December 28, 1998 SUBJECT: Additional explanation for Change Order Request #4 & #7 Change Order Request #4 deals with the changes for the connection to the existing M.C.E.S, structure. i .. Your contention is that since we bid all the depths at the same unit price the costs associated with the cormection change to the M.C.E.S, structure would be included within the different depth zones. ~rhe reason that the unit price is the .same for the various depth zones is that the total costs for the 'work as indicated on the plans was divided by the total footage, thus the same uni.t price. For example, if we figured that to install say 1,000 feet of pipe at the different depths came at a cost or$IO,OOO, this $10,000 would be c;ijvided by the total length of pipe of 1,000 feet, or $lO.001If, for all the different pipe depths. Since we had to do additional work above what was indicated on the original bid for the connecpon to the M:C.E,S. structufe, we experienced additional costs to inClude but not limited to; additional excavation; additional dewatering; etc, as indicated on Change Order Request #4. Now if you take these additional costs say of $5,000 and add them to the original costs you now have a total cost of $15,000. If you take this $15,000 and divide it by the 1,000 feet YOtl come up with a limit cost of$15.00ilf. You can see that your contentiorrthat our costs are included in our bid for ~he different pipe depths is incorrect. Subsequently, we expect payment to reimburse us for . the additional work"'associated with the change to the connection for the M.E.C.S, stmcture of $24,611.34 of which $4,400.00 has already ~een approved for processing. Since preparing Change Order #4 we held 'a joint meeting and after discussion we teel that Change Order #4 should lJe changed to the amount of $22,611.34 of which $4,400.00 has already been approved for processing. Also noted at said joint meeting was the wrong date on one of Our field work orders ()f July 15 and 16, J 998, when it should have been July 16 and 17, 1998 as ind.icated on your records. An Equal Opportunity Employer 12-28-1998 01:29PM FROM S.M. Hentges & Sons, Inc. TO 4474263 P.03 Change iOrder Request #7 deals with the existence of a concrete duct bank and a fiber optic cable - instead bfthe telephone li~ as indicated on the plans. Since y<?u only indicated a telephone line on your bid drawings and did not indicated the exis[ence of what twas actually there, a concrete duct bank/fiber optic line, we did not have money in our bid to cover the additional costs to cross it with the water services as indicated in the Change Order Request. . When installing just water services, we expect that one crew working 10 hours should be able to , install approximately 8 water services per, day. We only installed approximately 4 water services per day ldue to the concrete duct bank/fiber optic cable, You indicated that we were installing 4 servicesi per day along Pleasant. This is correct, but these services co~tained 2 lines, a water service ~long with sanitary'service. Although in the same trench, one had to be backfilled while the othdr was installed. BeCause this concrete duct bank/fiber optic line was not indicated on the plans Pr10r to the bid as required by Minnesota Statues 1996, section 2160.04 as amended we did not havf money in our bid ~o cover the additional costs for crossing this concrete duct bank/tiber optic lirie as indicated in the Change Order Request #7 in the amount of $26,591.50 of which $9,716.~0 has already been approved for processing. We would consider changing the additional time for each service from 2-1/2 hours to 2 hours for the eleven services and eliminating the $1 ,8oo.bo charge for 16541 and Valley Sign, resulting in Change Order #7 changing to $22,31~.50 of which $9,7i6,OO has already been approved for processing, , . r\""ct:;~ "\ ~ :o.....~" '....
