Box 9277 Corpus Christi, Texas 78469-9277 RE: AMENDMENT NO. 1 TO PROFESSIONAL SERVICES CONTRACT Elevated Water Storage Tanks -Citywide(ACR Implementation) City Project E16290 Mr. Edmonds: In response to the City's request, we are proposing Amendment No. 1 in the amount of $18,500 to provide additional services for the Elevated Water Storage Tanks - Citywide (ACR Implementation) project(E16290)for a total re-stated project fee of$690,534. PROJECT BACKGROUND On October 13, 2016, LNV received formal Notice to Proceed (NTP) letters for the Elevated Water Storage Tanks - Citywide (ACR Implementation) project (E16290), which will provide the City with a 2.5 million gallon (MG) elevated storage tank (EST) at Starry Road and a 1.25 MG EST at Nueces Bay Blvd., as outlined in the Alternative Capacity Requirement (ACR) Implementation Plan. This project also includes the demolition of the four (4) existing ESTs in the City's Pressure Zone 1, which have been identified as Morgan EST, Gollihar EST, Alameda EST, and Flour Bluff EST. The original contract amount for the Basic and Additional Services associated with this project is $672,034. PURPOSE OF AMENDMENT NO. 1 The purpose of Amendment No. 1 is to provide assistance to the City by performing a modeling evaluation of the manner in which the Flour Bluff area receives water from the mainland. Currently, the following three (3)water lines are capable of providing water to the Flour Bluff area of the City: • 8" line that runs north of South Padre Island Drive • 30" line that runs along Holly Rd. • 42" line that runs along Yorktown Blvd. (currently out of service) Page 1 of 3 AMEND. NO. 1 801 NAVIGATION I SUITE 300 I CORPUS CHRISTI,TEXAS 78408 EXHIBIT A OFFICE 361 883.1984 I FAX 361.883.1986 I WWW LNVINC.COM PAGE 1 OF 4 • . r • As a result of the current status of these lines to Flour Bluff, recent water quality challenges, and the imminent installation of new ESTs under the original contract, the City has requested the use of water modeling to achieve the following three(3)objectives: 1. Provide redundancy with respect to water delivery to the Flour Bluff area 2. Improve water quality in the Flour Bluff area 3. Determine the appropriate location for the Starry EST SCOPE OF WORK BASIC SERVICES(NIA) ADDITIONAL SERVICES: 14.Water Modeling An additional budget allowance of$18,500 has been requested under Amendment No. 1 to provide water modeling support to the City to achieve its stated objectives. To perform this service, the current City of Corpus Christi Hydraulic Model will be used, along with the pipe and valve configuration data provided by the City. With this information and the current model,the following scenarios will be evaluated: • The delivery of water from the mainland with varying combinations of existing water lines to Flour Bluff • The delivery of water from the mainland with additional scenarios to include the reduction of the existing 42" water transmission main by sliplining (maximum of two (2) line sizes to be modeled) NOTE: The proposed future EST configuration will be used for this analysis and will be limited to a total of eight (8) scenarios. Each scenario will be evaluated for its impacts to water system pressures and overall water quality. At the conclusion of this water modeling effort, The ENGINEER will provide the City with a DRAFT modeling report that describes the impacts of the various scenarios on the water quality and system pressures throughout the City to aid the City staff in its decision-making regarding changes to the water system. Upon receipt of comments from the City, the ENGINEER will update and submit one (1) hard copy and one (1) electronic copy of the FINAL modeling report for the City's use. Page 2 of 3 AMEND.
