Magney has completed the concrete pours for the reservoir as well as most of the concrete pours at the subgrade level of the Water Treatment Plant. Magney has also completed both the Backwash Tank and Clearwell base slabs and walls, top slab for the clearwell, and are starting to work on the top slab for the backwash tank. Our engineering team has continued to coordinate with Magney and further refine the installation details of other pieces of equipment. Through those investigations we have identified some items that will require adjustments. This letter is intended to outline those adjustments and summarize the current project budget in order for the City to fully understand the status of the project. Basis for of Construction Contingency Expenses: Currently fifteen (15) requests for pricing (RFP) have been submitted to Magney. A full list of those requests are shown below. To date AE2S has received pricing back on all fifteen (15) of the RFP's, and eleven (11) separate proposals. We would like to move forward and process Construction Contingency Expense No. 6, which will include price Proposal No. 022, No. 023, No. 024, No. 025, and No. 026. If the Contractor would like to include a request for extension as a result of these changes, a formal Change Order request will be issued at a different time.
