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

RESPONSES TO QUESTIONS AND REQUESTS FOR CLARIFICATIONS

Question 1: We are assuming that on dwg. E-201 that the panel LP-1 (see note 20) is the same panel as SN lighting panel (see note 23). Is this correct?

Response: LP-1 is the correct nomenclature for the Panelboard. "SN" stands for solid neutral bus supplied with Panelboard.

Question 2: DWG. E-205 SMS System. Note #1 indicates Contractor (assume electrical) shall provide UPS. But in the diagram #5 it indicates to reuse existing mini-ups. Which is correct?

Response: See revised Drawing Sheet E-205. The Contractor must reuse the existing mini-UPS for the proposed pump controller. A new mini-UPS shall be provided for the SMS network equipment.

Question 3: DWG. E-205 SMS System. Also indicates Contractor (assume electrical) shall provide the Network switch, but since the phone system is being provided by CDA wouldn’t the switch be part of that system? Which is correct?

Response: The Contractor (or the Contractor’s Electrical Subcontractor) must serve as systems integrator for all other systems interfaces (i.e. Mini-UPS, Fire Alarm Sensors & FACP, and Gas Detector) except for Pump Controller supplied by Pumps Manufacturer. The Contractor must provide conduit and cabling installation according to shop drawing per Pump Controller Manufacturer. Siemens will provide all the proprietary communication network cabling and telephone equipment under the CDA Siemens Monitoring Systems Update Allowance.

Question 4: DWG. E-201 Note #30 indicates Gas Detectors and Fire Alarm Sensors and Panel shall be provided and installed by others. Is this correct? While DWG. E-205 SMS Systems indicates monitoring of the systems will be by Electrical. Is this correct? Will this present an issue between the Systems provider/installer and the Electrical?

Response: Drawing Sheet E-201 has been revised to remove the "By Others" designation. However, the Gas Detectors and Fire Alarm Sensors and Control Panel will be provided and installed by the Contractor. All controller communications must be compatible with the current Siemens Supervisory Monitoring System communications architecture and protocols for transmitting digital data to ORD Central Monitoring Center.

Question 5: DWG. E-205 SMS System. The diagram indicates a plug strip shall be provided There does not appear to be a catalog number or type indicated. Please provide this.

Response: Provide 120 VAC power strip with a minimum of four (4) receptacles and 20A rating as shown on revised Drawing Sheet E-205.


Question 6: DWG. E201 shows (2) smoke detector/visual devices. The same appears to be indicated on DWG. E-205 SMS System (although shown without the visuals). DWG E-203 Elevation (facing West) shows an additional smoke detector in the pump well. Is this correct?

Response: Drawing Sheets E-201, E-203, and E-205 have been revised to show all smoke and gas detectors. Smoke detectors are visual devices/non-audible and there is a 3rd smoke detector in the pump well.

Question 7: This project calls for a Polyurea Liner in the lift stations Wet well. There is not a specification in the contract documents for this Work. Can you please provide one? So we know what product to use. Below is a copy of the notes in the plans(S-101), which does not give us enough information:

Response: Note #2 on Drawing Sheet S-101 has been revised to provide product specifications for the

polyurea lining.

Question 8: The purpose for my email is to confirm the type of pump required for this rehab. Flygt Submersible Pumps which are frequently used and installed at O’Hare are named in the Specification; however, from the Drawings it appears that the new pumps will be Conventional Line Shaft Dry Pit Units with the motors mounted on the Top Deck and the Hydraulic portion mounted in the Dry Well below. In addition, Morris Conventional Dry Pit Pumps are named on the Drawings Schedule MP-204. My question is that the General Specifications Section #15540 as written appears to require a Submersible Dry Pit Unit with the Motor, Shaft, Hydraulic in one compact unit installed in the Dry Well with no shafting or other pieces required and the pump directly connected to the Suction and Discharge. If you could kindly clarify it would be very helpful because I am getting many calls from General Contractors asking for clarification.

Response: Pumps will be dry well type. Section 2.03.D.1 of Specification Section 15540 has been revised to remove the reference to a submersible pump.


Question 9: I've been looking over the specifications and drawings for the I-190 Lift Station Replacement project, and have a few questions concerning the polyurea lining that is to be applied to the walls and floor of the wet well. Aside from the last two pages of the drawings where it shows the location of where the liner is to be applied, I do not see any technical information regarding the polyurea lining (product spec's and physical properties, brand, thickness, installation procedure, etc.). Do you know if this information is in the spec and where to find it?

Response: Note #2 on Drawing Sheet S-101 has been revised to provide product specifications for the polyurea lining.

Question 10: Drawing E-201, Specific Notes #9 says Contractor is to verify motor starter for sump work, if not replace. Since we cannot verify whether or not it is operation prior to bidding, we will assume, unless informed otherwise, that it is currently operational. Specific Notes #15 says Contractor is to measure existing building system ground and provide additional ground rods if measurement is higher than 25 ohms. Since we cannot verify the measurement prior to bidding, we will assume, unless informed otherwise, that it is existing measurement is less than 25 ohms and not include any additional ground rods in our proposal.

Response: Note #9 on Drawing Sheet E-201 has been revised to require replacement of the motor starters for the sump pump. Note #15 on Sheet E-201 has been revised to state that the Contractor is to provide an additional two (2) ground rods.

If the lead pump fails to start or experiences a failure the associated pump “fault” light will be lit and an alarm signal will be sent to the SMS, and lag pump will start. If the lag pump has started and the level continues to rise, the next lag pump will be energized. If the lag pump fails to start or experiences a failure, the associated pump fault indicator light shall be lit and an alarm will be sent to the SMS. If the level continues to raise the “High Wet Well Level” an alarm signal will be sent to the SMS remote central station for annunciation. A local horn shall locally indicate a “High Wet Level” has occurred. The horn shall be provided with a silence button, but the alarm signal will be maintained until the condition changes. As the Wet Well level drops, the pumps will be de-energized as the corresponding level are detected. Upon successful completion of Lead, and Lag if needed) pump cycle, an alternator shall switch its designation of lead and lag pumps.

B. A separate level air pressure switch will be used to detect a “High High Wet Well Level indicating the liquid level has exceeded the maximum line for safety of operation of the Wet Well. The “High High Level” alarm shall energized all the lead lag pumps for simultaneous operation, and sends a “fault” signal to the SMS central station for remote alert emergency annunciation.

C. Provide Wet Well Pump Control Panel with the following items: All indicating 30 mm LED type.

1. Pump not Running Lights (1 per pump)

2. Pump Run Lights (using existing flow switches) 1 per pump
