This is <br />limited to the footing/standpipe assembly that will hold the sprinkler heads in the base bid <br />system. Our structural engineers will design an appropriate footing and mounting system for the <br />gun: style heads. A single typical detail this footing/mounting system will be produced rather <br />than custom designing something for each head location. <br />We will rely on our irrigation designer to produce a layout of the system piping, valves and heads <br />as well as the electrical control system. It is our understanding that the City is comfortable with <br />these elements of the system being designed without the review of a registered engineer. <br />BIDDING <br />Our proposal in June contemplated a single bid for the entire project. In the time since then, we <br />have discussed the advantages of splitting the work into three separate bids. We agree with this <br />approach, but recognize that this will take some additional effort from our administrative staff. <br />FEES <br />Item Previous I Current Total <br />Authorization Authorization <br />Preliminary, Pre-Project Work <br />$47,300 <br />$47,300 <br />Project Coordination & Design <br />$51,570 <br />$51,570 <br />3 Project Bids <br />$4,100 <br />$4,100 <br />Alternate System Investigation <br />$1,200 <br />$1,200 <br />Structural Design <br />$2,200 <br />$2,200 <br />Irrigation Designer <br />$1,500 <br />$1,500 <br />Total <br />$98,87' O $9,000 <br />$107,870 <br />This scope and budget is based on discussions with City staff regarding the general need for <br />engineering review of the proposed base bid sprinkler system. <br />msg�� <br />TOM 0 -me <br />Mark Statz <br />City Engineer <br />651-604-4709 <br />iN <br />
