Thompson, City Manager DATE: March 17, 1999 BACKGROUND: On February 22, 1999 the City Commission approved an Interagency Agreement between the Jacksonville Transportation Authority (JTA) and the City of Atlantic Beach for Construction of Sewer Mains on the Wonderwood Connector Segment 2A. Article 2 of the Agreement addressed the cost which was an amount of $538,200 based on the original opinion of probable costs by our Design Engineer, The R-A-M Professional Group, Inc. of $534,549.93 (say $535,000.00) plus the original cost of $3188 (say $3200) by the Bridge Designer, Ralph Whitehead Associates, Inc. to accommodate R-A-M's design. With 'the 5% contract administration fee of $26,910.00 to JTA, the total construction related cost was $565,110.00. On March 15, 1999 we received a copy of an incorrect "final cost breakdown" sent to the JTA's General Consultant, RS&H, for $736,667.20. Upon inquiry by Bob Kosoy, Director of Public Works, on March 15, 1999, R-A-M advised their final estimate was in error due to improper metric conversions, and a $40,000 error in the original estimate. They submitted a revised estimate of $644,765.60 on March 15, 1999. This new estimate does not take credit for any savings by bidding with the JTA, and JTA feels that until bids are opened, we should not assume any savings, but base the agreement on estimate figures only. In addition to this cost is the final cost from the bridge design firm of $5324., or a total construction cost of $650,089.60. With the revised 5% contract administration fee of $32,504.48 to JTA, the total construction related cost is estimated at $682,594.08. The numbers in the contract do not reflect any cost savings by bidding the project with JTA and cannot be verified until bids are received. The bid opening will be held on March 24, 1999 and the figures will be adjusted at that time. The total amount budgeted for the Wonderwood Project in FY 98-99 is $600,000 and this agreement would require a budget adjustment of $110,500 to include R-A-M's consultant fees of $27,900. RECOMMENDATION: We recommend the City Commission approval for the City Manager to sign the Interagency Agreement between JTA and the City of Atlantic Beach and authorize a budget adjustment not to exceed $110,500. As discussed with Nelson Van Liere, Finance Director, these funds are available from reserves in the Sewer Utility Fund Balance. ~'"'1 ATTACHMENTS: Four (4) opinions of probable cost by The R-A-M Professional Group, Inc.

ATLA'~TIC BEACII, FLORIDA 32233-1381 -~'- TELEPHOIQE (904) 247-5834 ~~,_ ~~ FAX (904) 247-5843 March 16, 1999 Mr. Wayne Reed President The R-A-M Professional Group, Inc. 4655 Salisbury Road, Suite 210 Jacksonville, FL 32256 RE: Change in Cost Estimate - Wonderwood Connector Dear Mr. Reed: On February 1, 1999 your firm prepared an Opinion of Probable Cost for the referenced ~ project of $593,944.37, which included a 5% contingency of $24,341.98 and a projected savings by incorporation into the Jacksonville.Transportation Authority (JTA) project reduced the estimate by 10% to $534,549.33. Based on your firm's Opinion of Probable Cost, minor costs for revisions of the bridge plans to accommodate your design, and administration fees by JTA, we entered into an Interagency Agreement with JTA, approved by the City Commission on February 22, 1999, for $565,110.00. Including your engineering fee of $27,500 for this project, our budget of $600,000 for the project was still intact, as represented to the City Manager and City Commission. On February 25, 1999 your firm submitted a revised Opinion of Probable Cost of $583,732.03, which included a 5% contingency, but did not take credit for any projected savings in bidding with the JTA. This estimate was lower than the February 1, 1999 preliminary estimate.since a projected savings of $50,000, less than the previously assumed 10%, estimated the cost at $533,732.03 and, therefore, the agreement with the JTA needed no modification. During the week of March 8, 1999, at the direction of the JTA, your firm was required to resubmit the estimate in metric format in order to be consistent with the metric plans. On Wednesday, March 10, 1999 Frank Gray informed me that there was still an interference at the storm drain in the vicinity of Station 401+70, and that this would require extending the new sanitary line across Mayport Road to tie in to the existing ~, sewer on the east side of Mayport Road. I informed him that this was not an option ' because of the tremendous cost, which I quickly estimated to be at least $100,000. Wayne Reed March 16, 1999 Page Two On March 15, 1999, I received a copy of a revised "final cost breakdown" which you had faxed to the JTA's general consultant, RS&H. The estimate was for $736,667.20. This estimate was more than a 26% increase over your February 25, 1999 estimate, and was forwarded to the JTA's general consultant without any discussion with me about the increase. I contacted you on March 15, 1999 and you apologized for this failure to inform me of this increase, and you stated you were still revising the estimate. At 10:00 a.m. you informed me that the estimate was approximately $607,000 and the mistakes were due to "metric conversions", and that I would receive a faxed copy of the estimate immediately. At 2:10 p.m. I received a faxed copy of the revised Opinion of Probable Cost of $644,765.60. Your explanation of the $37,000 increase from your explanation in the morning was that "the original estimate was $40,000 too low." In summary, we will be required to revise our Joint Participation Agreement with the JTA for over $60,000. You were advised to obtain estimates prepared by RS&H and BH&R, both consultants for the JTA, and compare your cost figures to theirs. Be prepared to explain the reasons for the change in the Engineer's Opinion of Probable ~~ Cost to the City Commission on Monday, March 22, 1999. Sincerely, ~- ~~ Robert S. Kosoy, P.E.
