4% REDS www.ae2s.com Proposal No. 041 — Plate Settler Flow Meter Locations: To ensure accurate operation of the flow meters for the sludge pumps (SLP1 and SLP2), the Engineer is proposing relocating the meters and modifying the piping to create a low point in the run, ensuring the meters remain in a fully flooded section. Operating under constant full flow will improve meter accuracy, assisting the City in reporting more precise waste flows from the WTP. This proposal includes the labor and materials required to modify the piping and relocate the meters along with the associated electrical work. Proposal No. 044 — Generator Panel Feed: During construction, the electrician brought up a concern with the 60-amp size of the wire to the generator feed panel. Discussions with the generator manufacturer indicated that the load on the panel would be a maximum of 60-amps. However, to ensure maximum capacity is met, the Engineer recommends upsizing the feeder circuit to 100-amps capacity. This proposal includes the necessary labor, material, and equipment to provide a higher amp feed for the generator panel and a credit for the originally scheduled wire size. Summary of General Construction Contingency Costs: As part of the Contractor's bid, the Owner required a $950,000 General Construction Allowance. This allowance was intended to limit Contract changes due to change orders by applying general construction changes to a set contingency. The allowance represents approximately 3% of the overall construction bid price. For projects of this magnitude, industry standards typically see an increase in the bid price of 3% to 5% due to change orders, so it is expected that most of this allowance will be used by the conclusion of construction. Any unused funds from the allowance will be deducted from the project's Final Payment. AE2S has summarized all known construction contingency expenses below, to help the City of Ramsey better understand the current contingency status. With the approval of Construction Contingency Expense No. 10, the total approved expenses will total $608,734.41 of the existing $950,000.00 General Construction Allowance. As construction progresses, AE2S will continue to provide cost updates and coordination with City staff.
