1. Selection Criteria

The selection criteria and weightings for project selection are as indicated in Section 5, Selection Criteria.

The SOQ will be used by City staff to select the most qualified consultant. After the initial scoring by staff, the

City may ask the top 2-3 respondents for a brief interview. The interview step may not be required depending on the qualifications received, but if interviews take place, they will be during the 1st or 2nd week in

September. If an interview is required, the City is currently anticipating a Teams meeting, in which the consultant would prepare a brief 10-15 minute presentation before a question and answer session. After the interviews, the City would potentially revise the scores in the selection criteria categories and then make a selection of the top ranked consultant.

All consultants who submitted qualifications will be notified when the results are finalized, along with the top 3 selected consultants and their overall scores. Additional results and scoring breakdowns will not be provided.

The top ranked consultant will be notified and the final scope and hours will be negotiated. If an agreement cannot be reached with the top ranked consultant, the City will start negotiations with the next highest ranked consultant. The engineering agreement format will be Time and Material, Not to Exceed. Approval of the engineering agreement is subject to approval by the City Council.

The City of Aurora reserves the right at any time and for any reason to cancel this consultant procurement process, to reject any or all SOQs, or to accept an alternative SOQ.

2. Project Details

The project is located at the Aurora Water Treatment Plant (WTP), 1111 Aurora Ave., Aurora, IL 60505, which has 5 lime sludge lagoons. The map in the attachment section shows the locations of the lagoons.

• Lagoons #2 and #5 east of WTP building are concrete lined

• Lagoons #1, #3, and #4 north and west of WTP building are clay lined o Lagoon #1 has PCC wall around the top only

• All sludge is removed with an onsite excavator, loaded into semis, and is land applied or disposed of at a landfill.

• Lagoons #3 and #4 - sludge is removed and excavated from both sides of the lagoon

• Lagoons #1, #2 and #5 - sludge is removed and excavated from 1 side of the lagoon

• Bottom and center of Lagoons #3 and #4 have a 15’ wide PCC bottom with perforated drain tile running longitudinally down the center

WTP softening lime slurry is drained by gravity to the lagoons, once full and solids sufficiently dried, lime sludge is removed with a long reach excavator and land applied or disposed of at a landfill. Drain tiles are present to remove moisture. Each lagoon has different layouts of perforated pipes to dry the beds, but generally these drains run longitudinally and transverse, sometimes in a diamond pattern and are covered with pea gravel to prevent floatation.

The city has various operational difficulties with Lagoons #1, #3, and #4. It is desirable to modify at least some of the clay lined lagoons to be PCC lined.
