2. For your information and use, starting below on this page of the amendment are questions and answers received during the solicitation phase.

3. The solicitation closing date will remain as

October 7, 2020, 2:00 pm, CDT.

All other terms and conditions remain unchanged.

QUESTIONS AND ANSWERS:

1. The drawings state the paved parking/turn-a-round areas shall be rough graded by the CDA City Contractor. Offeror assumes that this rough grade is +/- 0.1' from design subgrade and that this project will be responsible for fine grading, geotextile fabric, 6" of CA-6 aggregate and 4" of asphalt to meet proposed finish grade. Proposed finish grade shall be 1' below top of ALSF and Glide Slope finish floor or flush with top of foundations at RVR & PAPI locations. Please confirm.

The finished grade shall be 1’ below finished floor at the four shelters and flush at the RVR and PAPI locations. With the installation of 4" of asphalt and 6" of CA-6. Assume that 4" of existing grade shall be cut to make way for new pavement profile by FAA contractor at the four shelter sites.

2. As noted in the Special Specifications, all spoil that is hauled off-site shall be assumed to be CCDD acceptable. Any spoil tested that does not meet CCDD shall incur additional cost to the contract. Please confirm.

FAA confirms.

3. How is the Mid-Point RVR is to be fed electrically? 9R ALSF drawings show the

Mid-Point RVR fed from that location while drawing GS09R-C009, GS09R-E001 & E002 indicate the 9R Glide Slope feeds the Mid-Point RVR.

Please provide cable and ductbank size, quantity and location of the feed.

The MID RVR shall be fed from the 9R ALSF/27L

Localizer shelter site per ORD-D-ALS09R-E010.

Utilize existing CDA installed ductbank and handholes for the routing of the power (2-#4 5kV and # 6 green ground) and control (12PR #19 and

#6 green ground) cables between the two facilities. An additional drawing will be issued showing the route from the MID RVR to the 9R

ALSF/27L LOC site when it is received from the

City of Chicago. Right now, the drawing package only shows the route by the 9R Glide Slope site.

Connections to these handholes will be installed by this contract as delineated on

ORD-D-ALS09R-C002, ORD-D-ALD-G020,

ORD-D-RVR09R-C002 & ORD-D-RVR27L-E001.

4. Please refer to GS09R-C001 and GS09R-C002.

C001 shows a handhole ductbank/casing underneath the taxiway east of the 9R Glide Slope and C002 shows routing cables for the 9R RVR & PAPI north into the CED system for the cabling. Which one is correct?

Follow the route for routing the power and control cables for the TD RVR to the north utilizing the existing CDA route

(ORD-D-GS09R-C002). The FAA is verifying if this crossing actually exists or will be installed prior to our construction start/site turnover from the City.

5. Please refer to GS09R-C003. Is the ductbank that ties the HV handhole to the 9R Glide Slope

25KV transformer not shown but still required to route from HV handhole to transformer?

The ductbank is not shown, but it is still required from the step-down transformer to the 9R

GS shelter. A modified ORD-D-GS09R-C002 drawing will be issued depicting this new route.

6. Please refer to GS09R-C001 and GS09R-C002.

C001 and C002 both show different layout for the paved parking/turnaround area for the 9 R RVR.

Which one is correct?

Please follow ORD-D-GS-09R-C002 for the paving of the 9R TD RVR.

7. The schedule received in Section C of the solicitation requires 3 out of 4 of the buildings

to be constructed through winter and completed within 120 working days. The proposed start date of these sites puts the construction activities, namely structural and exterior work, that are most impacted by weather to occur during the winter season. There are some activities that cannot be performed with any temporary construction measures during these weather conditions. The activities that can occur will be executed in the poorest conditions and the quality of the work may suffer. Moreover, the time period between bid and award does not allow for sufficient time to submit, receive approval, and release material for construction within that time frame. This will affect our pricing.

Please clarify that pricing must be based on the proposed start and completion dates.

Due to the predicted weather, the FAA could entertain releasing the 120 day completion durations. The FAA does want the contractors to take advantage of advantageous weather conditions if they exist.

8. The Special Specifications state that the 27L

ALSF site will be available to start work on

November 15, 2020. However, we understand there are restrictions to working in this area due to other contracts. Please advise what those restrictions are and on what dates those restrictions are lifted.

The restriction is that the FAA cannot build above ground at this site until February 2021 due to the airspace determination.

9. The drawings only indicate bollards to be installed at the 27L ALSF site. Please confirm this is correct, or provide locations and quantities for the bollards to be installed.

Bollards will be required in the same manner and amount for the 9R ALSF site as the 27L ALSF site.
