REDS www.ae2s.com Proposal No. 046 — Explosion Proof EF Room 109: The Sump Pump Closet (Room 109) contains the sludge pit and receives sanitary drainage from the plate settler system before discharging to a manhole outside the building. Because this connection creates the potential for sewer gases to enter the room, all electrical equipment was designed to meet Class I, Division 1 (explosion -proof) requirements. During construction, it was discovered that the HVAC design tied Room 109 into adjacent spaces and did not include properly rated equipment. This proposal includes the explosion -proof exhaust fan, associated rated components, and all labor and materials needed to install the necessary ventilation modifications. Proposal No. 053 — Chlorine Tank Lifting Bar: The chlorine room is equipped with a ceiling -mounted monorail crane to safely move full and empty one - ton chlorine cylinders during plant operations. A dedicated lifting bar is required to properly connect the crane hoist to the cylinders and is essential for safe material handling. This proposal includes procurement of the required lifting bar. Proposal No. 054 — Closet 104 Ceiling Change: The Control Room (Room 103) serves as the main control room for the Water Treatment Plant, with the adjacent Closet (Room 104) housing critical control and low -voltage electrical panels. Although the plans originally indicated a sheetrock ceiling, City operations staff raised concerns regarding heat buildup, equipment access, and long-term maintenance. To improve conditions and provide full access to electrical infrastructure, it was determined that the ceiling should be removed and the space left open to the full height of the concrete structure. This proposal reflects a deduction for the framing and drywall work no longer required. Summary of General Construction Contin2encv 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. 12, the approved expenses will total $709,349.39 of the existing $950,000.00 General Construction Allowance. As construction progresses, AE2S will continue to provide cost updates and coordination with City staff.
