Item 4B rSC[TY OF Item 4B OUTHLAKE MEMORANDUM (August 15, 2017) To: Shana Yelverton, City Manager From: Rob Cohen, Public Works Director Subject: Approve Professional Services Agreement with Deltatek Engineering for repair and repainting of the 5 Million Gallon (MG) Pearson Ground Storage Tank #2 (GST) located near the northeast corner of Pearson Lane and Southlake Boulevard in an amount not to exceed $82,237. Action Requested: Approve Professional Services Agreement with Deltatek Engineering for repair and repainting of the 5 Million Gallon (MG) Pearson Ground Storage Tank #2 (GST) located near the northeast corner of Pearson Lane and Southlake Boulevard in an amount not to exceed $82,237. Background Information: The Pearson Ground Storage Tanks (GST) site is located at Pump Station No. 1 near the northeast corner of Pearson Lane and Southlake Boulevard (FM1709). The site encompasses two 5 Million Gallon (MG) steel tanks built in 1996. Tanks are painted periodically as preventive maintenance to prevent corrosion of the steel (rusting) and oxidation of the paint (discoloration). In 2008, the exterior of GST #1 (west tank) and the interior of GST #2 (east tank) were painted and limited repairs were performed. In 2015, repainting of the interior and exterior of GST #1 and exterior of GST #2 tanks was planned; however, problems arose regarding the work and the original contract was terminated. Only GST #1 painting was completed, while all work related to GST #2 was suspended due to the onset of peak water demand season and need for additional funding. The current proposal is to paint the interior and exterior of GST #2 while it is offline since the previously applied interior paint is approaching its lifetime. This would avert taking the tank offline again in the coming years. Deltatek Engineering has worked with the City for similar work and has performed well in the past. The scope with Deltatek Engineering includes the preparation of plans, specifications and estimates required for solicitation. Services during bidding and construction, quality assurance and testing are also included in the Item 413 scope of work and part of the proposal. The proposed schedule is to complete the design and solicitation by the end of October 2017. Task Fee Plans, Specifications and bid documents $55,187 Project Administration $2,050 Quality Assurance and Testing $25,000 Total fee $82,237 The repairs and painting of the tank are anticipated to begin early November 2017 and be completed by the end of March 2018. This construction time frame is typically the period when water consumption is the lowest in the City of Southlake. Therefore, adverse impacts to the customer base will be avoided. Financial Considerations: Funding for the engineering design of this project is available in Capital Improvements Program Utility Fund. Additional funds required for construction are being requested in the FY 2018 budget submission Strategic Link: The approval of this Professional Services Agreement links to the City's strategy map relative to the focus area of Infrastructure. The specific corporate objective that is met by this contract is to provide and maintain high quality public assets. Citizen Input/ Board Review: N/A Legal Review: The standard Professional Services Agreement has been previously reviewed by the City Attorney. Alternatives: The City Council may approve or deny the Professional Services Agreement with Deltatek Engineering for the repair and repainting of the Pearson Ground Storage Tank #2.
