ARKANSAS DEPARTMENTAL CORRESPONDENCE To: Fayetteville City Council From: Donald R. Bunn, Assistant Public Works Directort2' Thru: Charles Venable, Public Works Director Fred Hanna, Mayor Subject: Award of Bid Installation of Ultraviolet System Paul Noland Wastewater Treatment Plant April 20, 1999 Bids were opened on April 19, 1999 on the installation of the ultraviolet system for the Paul Noland Wastewater Treatment Facility. Multi -Craft Contractors, Inc. of Springdale was the only bidder on the job. The bid was in the amount of $424,988.00. A copy of the bid tabulation is attached. Multi -Craft Contractors agreed to deduct a total of $14,409.00 from the bid price provided the time for completion was changed to 140 days. The lengthened time for completion is due to the time needed to have certain electrical components manufactured. We are in agreement with the time extension, therefore the Construction Contract the memorandum from OMI reflects the adjusted bid price of $410,579.00. It is the recommendation of the Staff that the bid be awarded to Multi -Craft Contractors in the amount of $410,579.00 with a time of completion of 140 days from the time of a notice to proceed. The budget is sufficient to cover these costs. 4110 CO MI Memorandum To: Mayor Hanna and Fayetteville City Council Members Thru: Charles Venable, Public Works Director From: Billy L. Ammons (PCP) Project Manager ta Paul Hawkins (PCP) Maintenance Manager Date. April 20, 1999 Re: Bid Recommendation for Bid # 99-47 Please reference the attached agenda request for bid # 99-47. We recommend awarding the bid to the low bidder, Multi -Craft Contractors (MCC) in the amount of $410,579. MCC's bid does not meet the specifications in regard to the time of completion, but is apparently the best that can be done under the circumstances. Certain components of the electrical system needed for this installation are not 'off-the-shelf items and must be custom manufactured. The proposed time frame for project completion of 140 calendar days is not desirable, but will be acceptable. Bid # 99-47 deals with the installation of the new ultraviolet disinfection (UV) system for the wastewater treatment facility (WWTF). The equipment needed for this disinfection system has already been purchased and will be delivered in the next few months. Approval of this contract will allow work to go forward in preparing for the eventual installation of the UV equipment. WWTF personnel will work closely with the contractor in an attempt to expedite the project in whatever ways may be possible. We appreciate your assistance in this important project. in -low c o r m- . ~ m b h °N G j $ e v o c m3�o o rh o im ip r m o C) n -1 Q w D O CD N 10 an N m m m m, Jo c o 8')- � m CI Y .T7 O � AY A O V C 1 r V_ n C) p T o n { Vn p m -1 N 'a u I T o Y n m o I - 44_ 4 ._ n H N 6 6 CI N m n iD 0 0.C vC W y n r+ -4 I rrr � D I o I z Y CD A C) .4 - "CD y C - OI o < n y V 0 C o 1608 MILTI -CRAFT CONTRACTORS 5a1 751 4399 P.02/02 C) I Multi -Craft Contractors, Inc.

BID 99-47: UV A.2 page 3 • OMI MEMORANDUM TO: Charles Venable FROM: Billy L. Ammons DATE: April 1, 1999 SUBJECT: Agenda Request Mr. Venable, We have been working with Peggy Vice on getting things ready to advertise the bid for the installation of the UV system. This bid will be advertised on Sunday April 4,1999, and Sunday April 11, 1999, then be opened on Monday April 19, 1999. We would like to try and get this on the April 20, 1999 Council Meeting, even though the time will be short. Time has become short for the overall project as we have awaited a complete set of specifications for this job, but we still have a chance to beat the oncoming June 21, 1999 deadline if we can expedite this contract. Accordingly, we have included the attached agenda request for your review and approval, and would ask that you forward it to the appropriate destination if this is acceptable to you. We do have contingency plans in place to be able to continue to treat water legally under the new EPA rules, but doing so will be very labor intensive and expensive. We would therefore like to proceed as quickly as possible with this project. Thank you for your help!

Public Works Director Fred Hanna, Mayor Subject: Bid No. 99-47 Ultraviolet Disinfection System Installation Contract On February 16, 1999 the Council approved a contract with Trojan Technologies for the purchase of an Ultraviolet Disinfection System for the Fayetteville Wastewater Plant. The memorandum to the Council at that time noted that another contract for installation of the equipment would be presented at a future meeting. The bids for installation of the ultraviolet equipment will be opened on April 19, 1999. We are asking that the award of that bid be placed on the agenda for the April 20 Council Meeting.

The bid tabulation and award recommendation will be placed in each Councilman's box in the City Clerk's office just as soon as possible after the bid opening on Monday, April 19. The estimated cost of the installation is $450,000.00. The overall budget of $1,100,000 for the ultraviolet equipment and installation is not expected to be exceeded.

If certain parts of the work are not completed or if certain corrections must be t made in the work even though the work is substantially completed, the Architect/Engineer is authorized to determine the amount which in his opinion is required for completion and/or correction of the ' work, and such amount may be withheld from the final payment to the Contractor, pending the completion and correction as required. I 17 I L J The balance found to be due the Contractor shall be paid by the Contracting authority within forty (40) days after the date of the final estimate. Prior to filing for final estimates, the Contractor shall file with the Architect/Engineer a receipt in full from each manufacturer, subcontractor, dealer and supplier for all equipment and material used on the work and a complete release of all liens which may have arisen from this Contract. In lieu thereof, the Contractor shall file statements showing balance due or claimed on all accounts and the Contracting Authority shall have the right, if it so elects, to withhold sufficient money to pay such balances until receipts in full or satisfactory evidence of final determination are filed with the Architect/Engineer who may then make the final estimate. The making and acceptance of the final payment shall ' constitute a waiver of all claims by the Contracting Authority, other than those arising from incomplete or uncorrected work, unsettled liens, or from faulty workmanship or materials, and of all claims by the Contractor, except those previously made and still unsettled. L. I I I H I I I If the work has been partially, but substantially completed to the extent that all adjustments in the Contract sum may be made, the Architect/Engineer may, if material delay in completion is anticipated or if otherwise deemed in the interest of the work, make the final estimate, retaining, in addition to other requirements which may be specified under payments, an amount representing the cost of unfinished work. Such payment shall be under the terms and conditions governing final payment. Neither the making of the final estimate, or final payment, shall relieve the Contractor of his responsibility for faulty materials or workmanship, and he shall remedy any defects and pay for any damage resulting therefrom which shall appear within a period of one (1) year from the date of substantial completion. The Owner shall give notice of observed defects with reasonable promptness, and all questions arising under this paragraph shall be decided by the Architect/Engineer. 28.
