1 for returning the water to the irrigation system; design of the storm water force main; <br />2 coordination with and design by an electrical subconsultant to design the power. <br />3 2.3 Additional Rice Creek Watershed District (RCWD) Coordination- <br />4 WSB had anticipated coordination with Rice Creek to accommodate traditional approaches <br />5 to drainage treatment. Because of the custom and unique nature of this system, additional <br />6 correspondence, negotiation, and discussions with the District were required to establish <br />7 proper credit and permitting for the new system. Additional time was also spent to resolve <br />8 interagency coordination between the Minnesota Pollution Control Agency and RCWD. <br />9 2.4 Biofiltration Beds - <br />10 Original landscape design for the areas along Twin Lakes Parkway called for planting beds. <br />11 At the direction of the City, Hoisington Koegler Group and WSB investigated direct <br />12 application of storm water to these bids, converting them to biofiltration beds. Additional <br />13 plant types were researched and specified, special soil design to aid infiltration was <br />14 performed, special direct inlets were designed, the drain systems were researched and <br />15 specified, weir systems were designed, specified and detailed for drainage and aesthetic <br />16 improvements, and overflow/safeguard systems were calculated and designed. <br />17 3. Additional Services Phase 2 and 3 <br />18 3.1 Schedule and Budget Tracking /Invoicing: <br />19 With the additional time added to the schedule of the contract, the project manager must <br />20 perform additional monthly budget and schedule tracking. The duration of Phase 2 & 3 <br />21 design is expected to be three months. <br />22 3.2 Design Review Meetings: <br />23 Three additional design review meetings are anticipated for Phase 2 & 3 (one per month). <br />24 3.3 Biofiltration Beds: <br />25 Much of the design detail from the biofiltration beds can be carried forward as a template for <br />26 Phase 2. However, each bed is custom designed to match road grade, width, length, and <br />27 sidewalk offset. The proposed hours accommodates these custom calculations and design. <br />28 3.4 Lift Station Design -Phase 3: <br />29 In order to ensure to meet Rice Creek Watershed District requirements for Phase 3, it is <br />30 anticipated that a combination of pond expansion and use of the existing irrigation <br />31 reuse/infiltration system (installed in Phase 1) will need to be utilized. In order to get storm <br />32 water into the existing system, a small lift station will be required within Phase 3. <br />33 3.5 Miscellaneous Plan Sheets -Second Set: <br />34 As discussed in allocation of original design fee proposal, there are several sheets that must <br />35 be included and customized for each plan set. The work -required for these sheets must be <br />36 duplicated for each set, and the proposed hours reflect this effort. <br />37 3.6 Contract Document Preparation- <br />38 The documents needed for contracting, beyond the drawings and special provisions, must be <br />39 regenerated for each contract. Bid Advertising, Instruction to Bidders, contracts, bid forms, <br />40 etc., must all be reviewed and modified for a new contract. <br />4 <br />
