1 03 8/6/2024 We would request an extension of 3 weeks to the bid due date based on the requirements of the proposal, coordination efforts between subcontractors, specialty personnel, wildlife biologist, and archeological monitor needed to complete the technical write-up for the project.

Solicitation is extend to Tuesday 10 September 2024 at 1200

Eastern Standard Time. All proposal questions shall be received by

Thursday, 29 August at 100 Eastern Standard Time.

8/5/2024

2 04 8/13/2024 Can dredged material be re-used for backfill of the new pipe pile?

Dredged material can be re-used for material removed during driveline clearing. Material to be filled within pipe piles shall be a sandy material with less than 10% fines.

8/13/2024

3 04 8/13/2024 Are there any additional drawings of the existing dock on the North Island?

Yes, please see attached titled "NMI Docks Archive Drawings" 8/13/2024

4 04 8/13/2024 Is there any fill material under the precast panels on the existing North Dock?

Yes. Fill material is noted as Dredged Lake Bottom Sand wrapped in geotextile fabric. Please see attached reference drawings dated January 1987 (NMI Docks Archive Drawings).

8/13/2024

5 04 8/13/2024 The specifications state that the dredging is to be performed only by mechanical means. What is the reason for that and would you be open to other options?

We would be open to other options. Please review the soil borings, geotechnical data, geology, and site photos first though.

Mechanical means are anticipated to be required due to the high amount of cobbles present onsite. Hydraulic means have been attempted in the past and were not successful due to the cobbles.

8/13/2024

6 04 8/13/2024 Will new permits be in place prior to work commencing?

Permits acquired, pending, and needed to be acquired by the

Contractor are listed below. Permits will be in place prior to work commencing.

Design / Govt Furnished Permits Acquired

1. Land Use Permit - Leland Township Planning and Zoning

2. Land Use Permit – Glen Arbor Township Planning and Zoning

3. NMI Septic

Design / Govt Furnished Permits Pending

1. MI EGLE / USACE Joint Permit for Docks (PENDING)

2. Leelanau County Road Commission (PENDING)

4. NMI Water Distribution Systems (PENDING)

5. SMI Water Distribution Systems (PENDING)

Contractor Permits Required

1. Electrical

2. NPDES

3. Others, Contractor to verify.

7 04 8/13/2024 The North Island completion date according to

Attachment 1 - Project Manual Part 1 states, "Simultaneous work on NMI and SMI is allowed, however NMI dock construction shall be completed prior end of 2025 construction season". Based on conversations during the bid walk, it was suggested that the contract may have potential to reduce the dredging efforts by removing the dock first and allowing the sand to move on its own. If the new dock needs to be installed prior to the existing being removed, we do not believe that is feasible by the date set if waiting for the sand to move on its own is an option. Is there any flexibility in that completion date?

The requirement noted in Spec 01 11 00 Part 1.3.B. no longer applies following Amendment 01. All work must be completed by the end date of the project noted in the solicitation, 31

December 2026. The Contractor is responsible for scheduling and sequencing the work to be completed by the end date in accordance with all permit and compliance restricitons and/or black-out-dates.

8/13/2024

8 04 8/13/2024 Can we dredge outside of the specified dredging zones.

Please submit the locations of interest to better inform our responses. Dredging outside of the specified dredging zones will need to be reviewed for approval. Depending on the locations of interest, this may require engaging EGLE, USACE, NPS internal compliance, and the Michigan DNR.

8/13/2024

9 04 8/13/2024 In the bid the building has metal and architectural roofing spec’d can you please confirm with material you are wanting.

Per Specification 13 34 23 part 2.5.B, "Roofing shall be Fabral, 26-gauge, Horizon 16, standing seam panels, with 16 in covered width." Please see the referenced section for additional information including salient Characteristics.
