Magney Construction has <br />completed the concrete pours for the reservoir as well as most of the concrete pours up to 128' of the Water <br />Treatment Plant. Subcontractors have completed electrical conduit installation within the electrical room, <br />floor slabs throughout the facility and framing of the administration spaces. Subcontractors have completed <br />all CMU block work for the facility. Steel beam installation has been completed in the pipe gallery up to <br />elevation 128'. Waterproofing and insulation on both the walls and the lid of the reservoir have been <br />installed. Site piping has been installed for sanitary, raw, and fmished water connecting to utility in the right <br />of way. Process piping continues to be installed in the pipe gallery and is about 80% complete. AE2S' <br />engineering team has continued to coordinate with Magney and further refine the details of installation of <br />equipment. Through those investigations we have identified some items that will require adjustments. This <br />letter is intended to outline those adjustments and summarize the current project budget in order for the <br />City to fully understand the status of the project. <br />Basis for of Construction Contingency Expenses: <br />Currently nineteen (19) requests for pricing (RFP) have been submitted to Magney. To date AE2S has <br />received pricing back on eighteen (18) of the RFP's, and has received eighteen (21) separate Contractor <br />proposals. The Engineer has received all of the received proposals and recommends that the Owner move <br />forward with approving Construction Contingency Expense No. 9, which includes Proposal No. 032, <br />Proposal No. 36, Proposal No. 37, Proposal No. 38, Proposal No. 39, Proposal No. 40, and Manhole No. 1 <br />price changes.
