technical aspects of the project related to the work of this scope and to participate in Q&A during the meetings. An allowance of 48 hours is included in the budget for this purpose. • The Consultant will furnish a project site map that delineates the extent of pavement replacement for the overall project; differentiate between trench -patching, grind and overlay and full -width pavement replacement; and it will show where sidewalks will be replaced due to construction impacts. Deliverables: 1. Exhibit boards (approximately 2' by 3') for the following: a. Aerial Map showing Sewer M Project Area, residences and addresses (already prepared). b. Combined and Drainage Sewer Routing. c. Schematic Overview. d. Pavement Replacement. 2. Attendance and participation in two public meetings. Task 630 — 90% Phase 1 Detailed Design This task includes completion of Phase 1 design: • Completion of design of modified Phase 1 elements, as described in Amendment No. 2, from a 60% level to 100% level of design. Improved project coverage - sheets C203, C411, C460, C470, C480, and C490. • Addition of design of sewer separation for areas originally designated as part of Phase 2 that were subject to basement flooding during storms in August and September of 2013. Completion of sewer system as described above, from 0% to 100% level of completion. These include new storm sewers for: o Grand Avenue from 14th Street north to 10th Street and from 15th Street south to 17th Street. o Rucker Avenue from 11th Street to 10th Street. • Deletion of the proposed Grand Avenue Trunk Sewer between 14th and 15th Streets. • Completion of service to two 15th Street residents on abandoned CS trunk - Sheets C203 and C204 — changing from grinder pump to gravity sewer, to 100% design level. • Revisions to stormwater system and combined sewer conveyance, based on PSO3 studies. Specifically, these include: o Revisions to CS and SD trunks on 15th Street and new Grand Avenue Trunks to separately convey SD and CS to proposed utility bridge location, completion of design from 0% to 100%.. o Design for sewer crossing connections at 15th St. and Grand Avenue as needed. Revisions to Control Structure at 15th St for interim and Phase 2 implementation, completion of design from 0% to 100%.. • Revisions to flow measurement design, based on the above conveyance system modifications, with completion of design from 0% to 100%. Relocation of storm drain (SD) flow measurement; relocation of combined sewer (CS) overflow flow measurement; and changes to flow measurement technology from flumes to depth/velocity meters, with associated electrical and instrumentation elements.
