ENVIRONMENTAL A <br /> /Q�S SERVICES® <br /> CI <br /> Scope of Work <br /> As noted in "Project Description", above ADS Environmental Services, herein known as "ADS", will provide <br /> temporary flow monitoring services for Murraysmith, herein known as "Client".The work will be <br /> performed in three phases as set forth below: <br /> Phase I —Mobilization <br /> 1) Kick-off Meeting. Phase I will begin with a kick-off meeting between representatives of Client, City <br /> and ADS. The purpose of the kick-off meeting is to discuss project scope, establish lines of <br /> communication, set milestones, and set the project schedule. (Conference call or email kickoff <br /> meeting for small projects) <br /> 2) Site Locations. ADS will work with Client to identify/verify the location of monitor installations. <br /> 3) Site Investigation. Once the installation sites are provided to ADS, ADS field crew(s) will perform site <br /> investigations. ADS will utilize a 2-person field crew for fieldwork and comply with Federal <br /> standards for confined-space entry. The proposed flow monitoring location will be located, <br /> inspected, and verified for hydraulic suitability. ADS will also check for debris in the manhole that <br /> could impact data quality. <br /> 4) Site Reports. Site reports will be generated upon completion of the site investigations. The site <br /> reports will include a sketch of the general location, physical characteristics and diameters of the <br /> proposed monitoring locations, manhole depths,flow measurements, and other comments <br /> pertinent to the location such as any special traffic or safety issues. Final site locations to be <br /> approved by Client. <br /> 5) Equipment. ADS will utilize the ADS® Triton+flow monitor during the course of this project. A <br /> typical monitor installation will include a peak combo sensor that includes in the same housing an <br /> up looking ultrasonic depth, redundant pressure depth, and continuous wave peak velocity sensor <br /> mounted at the invert. <br /> 6) Monitor Activation. Once installed,the monitors will be activated and set to take readings of at <br /> least 15-minute intervals. ADS Field crews will take manual depth readings with a ruler and velocity <br /> readings with a portable, instantaneous velocity meter in order to confirm the monitor is collecting <br /> accurate data based on the actual existing hydraulic conditions at each location. <br /> Phase II—Flow Monitoring <br /> 1) Flow Monitoring. Once the monitors are installed and verified to be in working order,ADS will <br /> monitor the flows for a maximum period of nine (9) months ("monitoring period").This initial <br /> monitoring period may be extended based on mutual consent and written agreement of additional <br /> work and price for such additional work. <br /> 2) Data Collection and Equipment Maintenance. A field crew will return to each location and perform <br /> site maintenance and site confirmations once during the monitoring period, unless otherwise <br /> indicated in the Pricing Table. ADS is an ISO 9001 certified company and has proprietary internal <br /> quality procedures for all fieldwork. This includes cleaning depth and velocity sensors, <br /> confirmations as needed, and checking an installation to make sure that the ring is secure in the <br /> pipe. The ADS data analyst will also review the data on a regular basis throughout the monitoring <br /> period. <br /> 3) Demobilization. Field crews will continue data collections and confirmations (as necessary) until the <br /> end of the monitoring period. Once authorized, crews will immediately begin removing the flow <br /> monitors and deliver final data to the data analyst. <br /> ADS,LLC <br /> 340 The Bridge Street• Suite 204 • Huntsville,Alabama <br /> All Rights Reserved <br />
