Attachment 1 To Amendment 2 To Work Order Number 4 Project Description and Understandin¢ This Amendment Number 2 modifies the scope of work in Work Order 94 and Amendment Number I to Work Order #4 for additional design and permitting for the Horizontal Directional Drill (HDD) installation of the Sub-Aqueous Utility Relocations, crossing the Wabasso River. The following scope of services consists of revising the plans to make the previously designed reclaimed (IQM or reuse) watermain into the presently proposed forcemain crossing of the Wabasso Causeway (CR510) from the mainland to the barrier island, and to design new watermain segments between the previously design HDD installations . The existing 12-inch forcemain and 12-inch watermain will be taken out of service, and used as a reclaimed watermain in the future. A new general permit for this forcemain construction is required for this proposed change to the original plan. SCOPE OF SERVICES The Scope of Services for Amendment #2 to Work Order 44 consists of the following : Task 1 .0 — Meetings and Project Permit Coordination No change to the previously approved Work Order for this task. This task is complete. Task 2.0 — Collection of Existing Data No change to the previously approved original Work Order for this task. This task is complete. Task 3.0 — Field Survey, Geotechnical Exploration, and Environmental Data Collection No change to the previously approved Work Order and Amendment one for this task. This task is complete. The consultant will provide Additional Survey that is required in the vicinity of the Marsh island entrance to locate the existing watermain and forcemain, which was not included in the original scope of this project. This area includes an environmentally sensitive area that will be located and shown on the survey to design the project for the construction to avoid this area, as the existing permit application described that all construction would occur in upland areas. The Consultant will provide Environmental Resource Permitting services in this area if necessary, as Additional Services. Task 4.0 — Design The previously approved Work Order and Amendment one for this task is complete, and is amended as follows . The Consultant will revise the reuse design plans to make the pipe on the south side on the causeway the proposed forcemain pipe, and design new watermain segments between the previously designed HDD installations. This will allow the conversion of the existing watermain and the existing forcemain into the IQM transmission piping that crosses the Indian River along the CR 510 causeway. Revisions to the plans consist of adding an additional design sheet, revising the design sheets to show the entire length of the causeway, to show tie-ins at each end of the project, designing tie-ins for the existing branches on the forcemain at Marsh Island, Wabasso Island Road, and the Indian River County Boat Ramp facility near H: %04457200'PNeopeMabasso HDD Proposal-Amendment 2 rev3. doe 1 of 3
