Box 9277 Corpus Christi, TX 78469 Subject: Citywide Lift Station Repairs 2018-2019 City Project No. E17086 Amendment No. 1 Dear Pablo: Further to our previous discussions, we are requesting an amendment to our present AE Agreement for additional civil design, structural design and electrical design necessary to complete the additional scope items. After preliminary research, site visits, and meetings with City Staff, additional work was identified and is described in the following paragraphs. The Williams Lift Station (LS) currently pumps to the existing headworks at the Oso Water Reclamation Plant. Currently a new headworks, approximately 27' higher than the existing headworks, is being constructed at the plant. As part of the original project scope, the existing pumps are to be replaced with new. Our existing fee was based on replacement of the same rated capacity pumps and did not include time to develop a system curve and select new pumps capable of pumping higher head. The Everhart Staples LS currently is in the dry pit/wet pit type configuration. The pump motors are in a building at ground level and the motor is connected to the pump at the bottom of the dry pit by a drive shaft. The existing dry pit sewage pumps are going to be replaced with dry pit submersible pumps. The dry pit submersible pump is a single unit with the motor attached directly to the pump. The proposed dry pit submersible pumps are considerably taller and heavier than the existing sewage pumps. Different options were considered for handling the proposed larger pumps and City staff would like to partially demolish the existing building and use a crane truck when the pumps need to be lowered into or lifted out of the dry well. The existing roof and three walls of the existing lift station building will be demolished. A new CMU wall and roof structure will be installed at the existing electrical room. As part of the original scope, this lift station is to have all new electrical installed. The existing AE Agreement does not include any time for structural design for major building modifications. A Structural Engineer will design the new CMU wall and new roof. Engineering services will be provided to obtain windstorm certification on the renovated lift station building (electrical room) at the Everhart Staples LS. The building will be inspected during the construction phase by a Texas Licensed Professional Engineer approved by the (361)854-3101 2725 SWANTNER DR. CORPUS CHRISTI,TEXAS 78404 FAX(361)854-6001 www.urbaneng.com TBPE Firm#145 TBPLS Firm#10032400 EXHIBIT A Page 3 of 7 Mr. Pablo Martinez December 18, 2018 Page 2 of 2 Texas Department of Insurance. Services include preparation of a WPI-1 form. At completion of construction of the building, a WPI-2-BC-5 Inspection Verification Form will be completed and a WPI-8 Windstorm Certificate will be obtained. As part of the original scope, the Williams LS and the Wooldridge LS will have new electrical equipment installed. The City Utilities Department has requested that electrical connections be installed as part of this project for the future electrical generators. Additional electrical equipment to accommodate a future generator will include an automatic transfer switch (ATS) and necessary connections points. The electrical engineer will provide design for these additional items. The proposed electrical improvements for both the Williams LS and Wooldridge LS include variable frequency drives (VFDs) for the new pumps. The VFDs will be installed inside of the existing electrical rooms and will produce significant heat as a part of their operation. A new HVAC system will be needed for both the Williams LS and Wooldridge LS to help offset the additional heat produced. We are now requesting an amendment to our present AE Agreement to include the additional work described above. We propose to perform the engineering services indicated for an additional fee of $47,880. A Manhour Breakdown of proposed amendment, updated Summary of Fees, and updated schedule are attached. Please review and let me know if you have any questions. We will be happy to sit down with staff and discuss at your earliest convenience. If acceptable, please have an AE fee amendment agreement processed.
