SECTION 2. QUESTIONS AND ANSWERS/CLARIFICATIONS

The following questions and requests for clarification were submitted in accordance with the instructions provided in the Contract Documents. The City’s response follows each question or request for clarification in the table below:

Question 1: Can the bid due date be extended 1-month?

Answer: The bid due date has been extended to July 17th, 2026.

Question 2: Sheet 19 of 56 Points to two locations and states “Contractor to design and provide ERS per Section 02 33 44. I did not see that 02 33 44 exists in the documentation shared. Please share.

Answer: Refer to Specification Section 02 03 44 Shoring, Sheeting, and Bracing.

Question 3: The Existing Force Main Profile is not shared from Sheet 19 to sheet 21 where the pipe connects back to the existing Steel Force Main. It is unclear what the depth of the existing main is and at what elevation it goes through the wall at STA 118+60. Can that information be provided?

Answer: Refer to Sheet 19 (C-13), CAP EXISTING 18” DI SFM (TO BE VERIFIED IN THE FIELD). The existing force main will be capped and abandoned at this location, refer to Note 3. Sheet 21 (C-15) Section A-A indicates an Invert Elevation of -9.75 for the 18” DI SFM. Section B-B indicates an Invert Elevation of -9.5 for the 18” DI SFM. The Contractor is responsible for field verification.

Limited reference drawings are provided with this addendum but may not reflect current conditions.

Question 4: Are the records of the existing 10” Sewer identified on Sheets 19-21. The pipe is nearly touching the existing 18” SFM from stations STA. 117+00 to STA. 109+55. Is it at the same elevation? Is it further away? Is it above head?

Answer: The 10” Sewer centerline elevation is approximately El. -8.5 through this area and is buried, similar to the 18” SFM. Note that work on SFM piping in this area is HDPE lining inside existing piping. Limited reference drawings are provided with this addendum but may not reflect current conditions.

Question 5: The only access identified to get underneath the deck/beams is show on Sheet 20 of 56 “Access Stairwell”. Can you identify the dimension of this doorway and any other access points to gain access to the excavation pits in this space?

Large amount of material to be installed, excavation required, large horizontal direction drill machine, pull equipment for the Compression FIT liner in this space.

Answer: Access to “void space” requires travel through overhead doors (119” W x 94” H) and then double “man” doors (66” W x 81” H) within the lower dock area of the plant. CDWM will also consider removal of masonry walls within this area to provide access with design sealed by a Structural Engineer licensed in the state of Illinois and restoration to existing conditions following construction. Sheet 20 (C-

14) indicates the stairwell is between columns 30 and 31.

Question 6: Can the height from dirt floor to column be identified on the drawings at the pit locations?

Answer: The height from dirt floor to column is 80” at the location of the stairwell. Note that conditions change towards either end of the “void space” from this location.

Limited reference drawings are provided with this addendum but may not reflect current conditions.

Question 7: Under the decking, in lieu of a HDPE liner, can a new HDPE line be installed to be the Sediment Force Main? If so, can this be installed via open cut and/or mounting to ceiling. Also, can the new Bypass line be installed via, open cut and/or mounting to ceiling under the decking?

Answer: Bid the installation per contract documents. Installation of unburied piping within the “void space” will not be considered based on freeze condition concerns.

Question 8: Has this project been consider to bid as a Design-Build given the challenges?

Answer: The existing construction contract was pursued as the most appropriate method to accomplish the work.

Question 9: Please extend the question deadline a minimum of six(6) weeks, as additional time is required to review the bid documents and submit questions to City of Chicago.

SUMMARY

PART 1 GENERAL

1.01 SCOPE OF WORK

The Scope of Work under this Contract consists of but is not limited to furnishing all labor, materials and equipment to rehabilitate, replace or provide the following.

1. Improvements to the Jardine Water Purification Plant’s (JWPP) sediment disposal system by rehabilitating the existing 18-inch diameter sediment force main and providing a new permanent bypass pump and a new 16-inch HDPE bypass pipeline that can be used when the existing sediment force main is taken out of service for rehabilitation or in the future for maintenance.

2. The existing 18-inch diameter ductile iron sediment force main will be rehabilitated by insertion of a close fit HDPE liner. Insertion of the liner will be at access pit openings created at various locations along the force main route (both inside the JWPP void space and in the public right-of-way). For areas that have difficulty to be rehabilitated by lining, a new segment of 18” ductile iron force main will be installed. Various appurtenances including but not limited to line valves, air release valves, fittings and manholes shall be provided on the rehabilitated pipeline.

3. A permanent 16-inch HDPE bypass pipeline from the JWPP will be installed and connected to an existing 24-inch sanitary sewer along Streeter Ave between Grand Ave and Illinois St. The bypass pipeline will be installed by horizontal directional drilling (HDD) and open cut construction as shown on the plans. A transition manhole with a flap gate will be installed to transition from force main to gravity sewer. A level sensor will be installed to monitor permanent bypass pumping in the existing sewer and integrated into JWPP’s SCADA system to assist for plant operations. A backflow valve and vault structure will be installed on the permanent bypass line upstream of the connection point to the existing 24-inch sanitary sewer to prevent sanitary sewer backups into the bypass line in JWPP and will only be open when the bypass pipeline is active.

Contractor shall submit CCTV of the existing sanitary sewer segment that the permanent bypass line is connecting into along with downstream segments prior and after the installation of the permanent bypass line connection, including a total of approximately 800-ft long for 24-inch, 27-inch, and 30-inch existing sewers. CCTVs shall be submitted to City of Chicago Sewer Department for review and approval. Repairs or lining of the existing sewer must be made as necessary prior to the connection of the bypass pipeline as requested by the City of Chicago Sewer Department. Contractor shall also maintain the existing conditions of the existing sewer during and after the permanent bypass line connection. Contractor shall provide a total of three (3) cleanings for the existing sewer, including two (2) cleanings for approximately 800-ft existing

sewer immediately downstream of the connection point during the installation, and one (1) cleaning for approximately 2,800 ft existing sewer along Illinois St from Streeter Drive to the MWRDGC sewer near St. Clair Street after the construction is complete.

4. One new horizontal solids handling screw centrifugal pump and associated appurtenances will be installed in the JWPP -15.0 elevation level adjacent to the existing sediment wet well pumps. The new pump will be a permanent bypass pump that will be used when the bypass line is in operation and its discharge rate will be controlled by modulating the valve manually.

5. The 12-inch steel emergency discharge piping will connect to the new permanent 16-inch HDPE pipeline via a tee in the void space and have permanent piping to the outside wall of the void space near the road. Temporary piping and filtration system for the emergency bypass will connect to the 12-inch emergency piping at the outside wall of the void space near the road. The NPDES Permit obtained from IEPA is included in Appendix C. Contractor shall install a temporary filtration system that can handle up to 1,800 gpm, including but not limited to temporary piping to the filtration system, road crossing ramp, barge(s), sediment and waste disposal and associated testing, start-up and testing, staff training, to comply with the NPDES permit. No filtration equipment is allowed on the roadway between the void space and the slip. This set up shall be ready on site for emergency discharge during the entire duration when the existing sediment force main is taken out of service for rehabilitation until the rehabilitated sediment force main is back in service as approved by the Commissioner. Supplier Rain-for-Rent is the basis of design for the filtration system as shown in the Contract documents. The filtration layout will be determined by the Contractor with the final selection of their supplier.

Contractor shall prepare monthly Discharge Monitoring Reports (DMR) throughout the entire duration of the entire project, with or without the emergency outlet being used. If the emergency outlet is used, Contractor shall monitor the parameters and test and record the sample(s) including but not limited to flow, pH, total residual chlorine, and total suspended solids per the NPDES permit. Changes of the filtration process or addition of any chemicals are not allowed without written approval from IEPA.

6. Other miscellaneous project work will include alterations to walls, floors or slabs within the JWPP to accommodate the pipeline routings, alterations to existing discharge piping to facilitate connections and electrical and instrumentation work required for the bypass pumping system.

7. The existing sediment force main is to be taken out of service for rehabilitation in the summer months of June through August during the low turbidity season of Lake Michigan, unless otherwise approved by the Commissioner. The new permanent bypass pump and pipeline system and the temporary bypass and filtration system must be installed and fully operational as approved by the Commissioner before the existing sediment force main can be taken out of service for rehabilitation.
