CR 99-142 Approve Engineering Services Agreement Water Tower Repainting August9,1999 ,. y \ 0 .m .y CO o P K \ ~ Council Report 99-142 Approve Engineering Services Agreement Water Tower Repainting Staff recommends the adoption of the following motion: Move that Council authorize the City Manaaer to enter into an aareement with SEHRCM for the enaineerina services related to the reoaintina of the Moline Water Tower. Overview. The Moline Water Tower was built in 1967, it was painted Sky Blue. The second time the tower was repainted was in 1977. It was repainted for the third time in 1987. The tower was sand blasted down to bare metal to remove all of the .. Red lead Primer" and a new primer system was applied to the tower. The paint color that was applied was a custom blend and it was named U Hopkins Grey u. The paint system that was applied has failed and is in need of repainting. The tower has some other work scheduled to be completed during the repainting of the tower. The new paint system that will be applied should last another 10-12 years and possibly longer because of the new technology that Is available now. Primary Issues to Consider. . What is the estimated project cost? City cost? The estimated costs should be covered by the $500,000 that was entered into the Capital Improvement Plan. The cost of Engineering services is $45,220. . Project schedule Complete design: October-November, 1999 Award project: December-January, 2000 Construction: April, 2000 . Engineering Selection Process and SEHRCM engineering fees Engineering proposals were solicited from three firms. We received proposals from all three companies. Two of the companies are engineering companies that specialize in tower painting inspections these companies are: AEC Engineering and KLM Engineering. The other company is a full service engineering that covers all the aspects tower construction and painting. The staff selected SEHRCM based on their Qualifications, and because RCM designed the water tower originally. RCM was the engineer of the Well # 1 remodeling projec~ and numerous other water related projects in the past. SEHRCM fees are $45,220, which includes $32,320 for construction services. The City receives a 5% reduction or $2380 off the construction fees because of our award of the Water Treatment Plant # 4 work to SEHRCM. Some of the factors that led the selection of SEHRCM were, their offices are less than 10 minutes away so that problems can be resolved Quickly. All of the other cities that I talked to highly recommended SEHRCM and were very pleased with the out corne of their painting projects on their water towers. The colors that are being considered are the Minnetonka Ridgedale Tower "Cumulus" or 51. Louis Park Towers 'Warm Sun".

As discussed SEH will offer the City of Hopkins a direct fee reduction of $2380.00. or 5% for being awarded the Water Treatment Plant No.4 work per our proposal. This reduction places our fee at $45,220.00. It is our belief that fees regarding Pre-Design should remain. However, as outlined in our letter of June 29, 1999, our fees are based on an hourly not-lo-exceed. Therefore. further reductions to our fee may be realized by the City in the form of reduced time for preparation of the construction documents, and/or inspection lime depending on which contractor is awarded the project. We believe we have provided the City with a proposal that is all inclusive of the anticipated work for this project, and apprecialed the opponunity for further discussion. djz cc: Jim Norron, SEH-St. Paul Richard Potz, SEH*RCM Lloyd Pauly, SEH*RCM Dave Halter, SEH*RCM 1:\WTIlE^TlIIOPKI!IlS\~.rl~~IHII~')~ WPO Short Elliott Hendrickso., Inc.

SEH-RCM maintains a staff qualified to perform the required on-site testing and inspection associated with surface preparation and coating reapplication of water storage facilities. SEH-RCM services follow inspection practices and standards as set forth by the International Association of Corrosion Engineers (NACE), Steel Structures Painting Council (SSPC), American Welding Society (A WS), and the American Society of Testing and Materials (ASTM). Inspections include: ., Daily review of contractor's surface preparation, coating methods, and procedures; ., Inspection of contact materials such as abrasives, coatings, and additives for proper use and specification compliance; ., Observance of contractor compliance to current state and EP A environmental standards; independent TCLP sampling of generated waste material prior to disposal; ., Monitoring of daily ambient conditions; ., Recording of surface preconditions, surface cleanliness, and daily coating application information; ., Required testing and equipment calibration as defined in the specifications; ., Provide daily or weekly progress reports, as required, along with progress photographs. Inspection services will be conducted under the direct supervision of a registered professional engineer. 5. Warranty Inspection SEH-RCM will require the awarded contractor to provide the City of Hopkins with a two-year warranty on structural modifications and the replaced coating system. At the end of the two-year period, SEH-RCM will provide for a warranty inspection. Short Elliott Hendrickson Inc. Page 4 . r:- < < , ,c I i- F': [ : f---' 1 " le ~. .~ ~ . ::.. L..) General Scope of Work, cont. Work Plan - 2 MG Moline Water Tower After review of the dive inspection videos, as conducted by Liquid Engineering (LE), it is our assessment that it is in the best interest of the City of Hopkins to complete a total reconditioning of this facility. It is estimated that completion of this project will take 12 weeks. As discussed in our transmittal letter, that even if the exterior coating system is found not to be lead or chromium based, MPCA will require a containment structure to capture fugitive dust emissions. This is providing that some variation of a conventional abrasive blast method is used. However, this tanks configuration lends itself well to the use of a "vertical vacuum blast" system. The Wheelabrator system provides for coating removal that utilizes both grit and steel shot without the necessity for erecting an enclosure, since generated waste is collected by a vacuum arrangement. Furthermore, generated waste is significantly minimized because the abrasive is continuously recycled. Use of this system though is limited in use to the shell plate sections of the tank structure. Therefore, the "vertical vacuum blast" system would be used in conjunction with other available and approved methods to accommodate the roof and pilaster surfaces. SEH/RCM introduces this alternative, based on our interpretation of existing data and inherent site considerations, as a means of offering the City of Hopkins a cost efficient solution. SEH.RCM believes that the key to achieving desired expectations will lie in the successful scheduling, communication, and coordination between Hopkins City staff and the SEH.RCM project team. We are prepared to complete construction documents in line with the City's expectation to bid the project in November of this year. This early start will enable the City to take advantage of open contractor schedules for the 2000 construction season- attracting more bidders- and those most qualified to complete the work. Early planning will allow us to plan around special concerns directly related to this project: ... Consideration of wireless communications antenna and ground equipment ... Proximity to STH 169 and Excelsior Boulevard ... Water demands during tank down time As earlier stated, SEH/RCM will work directly with City staff, MPCA, and other concerned parties during pre-planning to address these specific issues. Pre-Design In this phase of the project, SEH.RCM will complete a final study of the structure and site as described in the General section of the General Scope of Work. Following this investigation, we will meet with City staff to formulate a formal project plan to meet long-term facility maintenance expectations. As requested, SEH.RCM will provide the City with copies of specific documentation used in the process of developing the project plan. Short Elliott Hendrickson Inc. Page 5 . I.. !

Design SEH-RCM will incorporate into its design plan required tank modifications as determined through further field investigation, outlined in the pre-design. Modifications already determined include: ... Addition of an exterior access ladder ... Repair of the interior ladder (with safety climb device) ... Grout replacement around the foundation ... Catch basin under the overflow outlet pipe ... Removal of approximately 30' of pipe and valve from the upper tank which fills the standpipe ... Upgrade of the electrical system Tank modifications, including pre-surface preparation, will enhance the serviceability of the newly applied coating system by reducing and/or eliminating defects where failures begin. These changes will also provide safety measures for future tank servicing and maintenance in compliance with current A WW A and OSHA safety guidelines. The inspection report and supplemental videos, as prepared by Liquid Engineering, do not furnish adequate information on coating thickness, condition of supporting roof rafters, and number of roof supports with respect to the tank interior. SEH-RCM will incorporate provisions into the specifications to address these items so that change orders in reference to these issues will be less likely. SEH-RCM will review, with City staff, the current operation of its water system to assist in determining the safest and most efficient means of continued operation while the tank is temporarily removed from service. Environmental Concerns Specific information regarding the interior and exterior coating systems, again, will be analyzed as part of pre-design. Paint chip sampling will determine if the existing coatings have residual lead or contain chromium to a level which would render them as hazardous. However, SEH-RCM will provide specifications in accordance with current MPCA air quality regulations covering the emission of fugitive dust apparent during the coating removal process. Although the removed coating systems may not be classified as lead and/or chromium based, SEH-RCM will provide measures for TCLP (Toxicity Characteristic Leaching Procedure) testing of generated waste to identify materials for disposal as hazardous waste. Personal air monitoring in accordance with OSHA "Lead in Construction" guidelines will also be implemented. These safeguards are incorporated into the specification as an additional means of liability protection for the Owner. Short Elliott Hendrickson Inc. Page 6 . F. :. ~ - -~ L ~.~~ l_ .. L__ General Scope of Work, cent. Inspection As presented under our General Scope of Work, SEH.RCM will provide an inspector trained to observe and work under the guidelines on NACE, SSPC and A WS. Our inspectors are also A WS and/or SSPC certified, and will provide observation during key phases of mobilization, structural modifications, and the reconditioning of the tank's coating system. SEH inspection services will include both full and part-time construction observation as necessitated by site activities. Full-time inspection will be provided during critical activities such as surface preparation for both interior and exterior surfaces. of the tanks. SEH.RCM believes in the importance of field inspection to assure our clients a quality product. Therefore, we propose a substantial presence during the entire project. This commitment will enable us to take a proactive role in addressing any difficulties which may occur during the length of the project. Short Elliott Hendrickson Inc.
