1 ATTACHMENT B STATEMENT OF WORK SCADA STILLING WELL/PLATFORM REPLACEMENT STORMWATER TREATEMENT AREA (STA), PACKAGE INTRODUCTION AND BACKGROUND The South Florida Water Management District (District) has established locations for collecting data at specified locations throughout its 16 county boundary. These locations use stilling wells to collect information on stages, flows, water quality and other parameters. Over time, many of these locations have reached the end of their useful life creating an unsafe condition or have experienced other issues preventing the proper collection of the data. This project will result in the replacement of stilling wells and platforms allowing District staff to continue to collect required data in a safe and continuous manner. 2.0 OBJECTIVE The objective of this project is to utilize a qualified Contractor to replace stilling wells and platforms located at G377B. See attached Exhibit A Site Map, for location and directions to each site. 3.0 SCOPE OF WORK The Contractor shall furnish all equipment, tools, materials, labor and everything known and necessary to complete all required Work as specified in this Statement of Work and the attached Technical Specification Section The Contractor shall determine the method, details and means of performing the services. The District may provide additional guidance and instructions to Contractor s employees, subcontractors or hired workers where necessary or appropriate as determined by the District. 4.0 PRELIMINARY MATTERS 1. Before Starting Construction Following purchase order execution, prior to Construction Notice to Proceed (NTP), Contractor shall submit to District for its timely review on or before the Pre-Construction Conference: 1. An initial cost-loaded construction schedule in accordance with the attached technical specification A preliminary schedule of submittals listing each required submittal and the times for submitting it.

2 2. Pre-Construction Conference Upon purchase order execution, the Contractor shall schedule a pre-construction conference with the District Construction Manager (CM) and Project Manager (PM), and others as appropriate. The Contractor shall prepare an Itinerary for use during the preconstruction conference. The Itinerary shall include: 1. An introduction to the Contractor s employees and/or subcontractors involved with building the Work. 2. An initial cost-loaded construction schedule in accordance with technical specification A preliminary schedule of submittals listing each required submittal and the times for submitting it. 4. A detailed plan of how the Work will be accomplished. 3. Notice-To-Proceed The period of performance of this project shall commence upon the effective date of a Notice to Proceed (NTP) and continue for a period as indicated on the signature page of the purchase order. The Contractor shall not proceed with construction work until a Notice to Proceed is received from the District. 5.0 WORK BREAKDOWN STRUCTURE Contractor shall perform the following tasks: Task 1: Stilling Well and Walkway Replacement 1. Obtain a C key through the Districts online request page: 2. Notify the District Construction Manager five (5) days prior to starting any construction so that they can have the stage parameters set to test. 3. The Contractor shall cut down, and then entomb the old HW and TW stilling wells. The wells shall be filled with a combination of the broken up concrete (no rebar) and new concrete. The mix should be thick enough to prevent it from coming out the transfer tubes. 4. At a pre-determined location agreed upon by the District Project Manager and the Contractor, install a walkway in a northerly direction perpendicular to the canal. The walkway shall extend far enough into the canal to allow a lower measurement of 6.8 (this includes 2 into the canal bottom.) The deck shall be constructed in accordance with the plans and specifications. 5. Provide and install a 12 stilling well at the end of the walkway using current District installation standards. Due to the rapid current expected during high water the stilling well shall be attached at three places (handrail, walkway and waterline), and shall be buried in the ground a minimum of 2. The well bottom shall be wrapped with well wrap to prevent the well from filling with dirt. Page 2 of 8, SCADA Stilling Well/Platform Replacement (STA), Statement of Work

3 6. At a pre-determined location agreed upon by the District Project Manager and the Contractor, install a walkway in a southerly direction perpendicular to the canal. The walkway shall extend far enough into the canal to allow a lower measurement of 6.26 (this includes 2 into the canal bottom. The deck shall be constructed in accordance with the plans and specifications. 7. Provide and install a 12 stilling well at the end of the walkway using current District installation standards.

The well bottom shall be wrapped with well wrap to prevent the well from filling with dirt. 8. Provide and install wellheads on both stilling wells, and then provide and install junction boxes in the back right corner of the wellheads; ensure the junction boxes do not interfere with the wellhead operation. 9. Provide and install a piece of 1 thick Starboard in the wellheads over the wells; the Starboard shall be aligned so that an encoder wheel can be positioned in the center of the wells and not have the Starboard interfere with the encoder tapes. 10. Provide and run new conduit from the old conduit to the front right of the wellheads through a traffic box, to the point where the old conduit starts. 11.
