Date Due Date Response

The requested Dark-Bronze vinyl coated mesh is not a factory option for this type of fencing.

Would black be acceptable?

5/12/2025 5/22/2025 Dark Bronze or equivalent (aka dark brown) would be the acceptible color options for the fence.

Will the temporary fencing be required to be installed before the existing fencing is demo’d?

Temporary fencing may be installed at the contractor's timing discretion. When the contractor is on site actively working the compound does not need to be completely enclosed.

Compound shall be enclosed at end of each work day with temporary fencing, if necessary. If using temporary fence, attach a controlled area sign to the fence as well ensuring area is fully enclosed and labeled.

3 01 35 29.13 - 1.5.1 With this project not requiring remediation is an industrial hygienist really needed?

No, an industrial hygienist is not required.

Does the temporary fence need to secure? We feel that the Orange snow fence may not be enough security for this area.

Snow fence will satisfy as securing the area. Snow fence may be utilized along with an attached controlled area signage to the snow fence to enclose the compound.

Are there any as-builts available for the existing equipment grounding? Or should we anticipate providing new grounding only?

Anticipate providing new grounding system.

The specification reference work on a contaminated site. Can the government provide any additional about this? Is the contractor to provide any soils testing or special consideration for where demo’d materials from this site are to be delivered or remediated?

No special requirements or testing of soil for remediation will be required.

Please confirm if NAVFAC eCMS will actually be utilized for this project.

NAVFAC eCMS will not be used for this project. This specification was an error.

Is a cost loaded p6 schedule required or is a AF3064 acceptable?

An AF 3064 is acceptable for cost portion, but a detailed time line schedule with major milestone and when to expect them is required.

Can the super Triple hat the SSHO/ QC roles if the role requirements can be met?

Yes

What items is the government considering as salvage that should be turned over to the government per specification?

There are no items designated for salvage for this project.

11 Spec 01 31 23.13 20

Section 01 31 23.13 20 says the project will utilize NAVFAC’s eCMS for all electronic communications, while Section 01 30 00 and other state that the USACE is running the project. Who in fact is overseeing this project and by what means are submittals, RFI’s, etc.

to be sent and received?

Disregard specification 01 31 23.13 20. This specification was an error for this project.

97 CONF is overseing along with 97 CES engineers and inspectors. All submittals, RFIs, etc will need to go to the contracting office to flow to the correct reviewers.

12 Spec 01 32 01.00 10

Section 01 32 01.00 10 says that P6 must be used for scheduling which is again a USACE and NAVFAC requirement and not a USAF requirement. If the USAF is running this project, then can we use the AF3064 for scheduling and the AF3065 for progress reports as on all other USAF ran projects? Or has the government accounted for the additional costs of the contractor hiring a scheduler for this project in their IGE?

An AF 3064 is acceptable for cost portion, but a detailed time line schedule with major milestone and when to expect them is required.

An AF 3065 is acceptable for progress reports.

Does the government want separate full-time on-site Superintendent, Quality Control Manager, and SSHO per specifications, or as on other USAF bases is just one individual who has the qualifications of all three sufficient?

One individual meeting the three qualifications is sufficient for this project.

Has there been any past spillage that has gotten into the concrete drainage system that we are to demolish and if so, will the ground beneath need to be tested creating the possibility of additional work outside of the SOW, like remediation and disposal of contaminated soils, import of new soils, etc.?

No spills have been reported in this area. No testing for soil remediation or disposal of contaminated soil will be required.

Spec 01 78 00 &

01 78 23

Sections 01 78 00 & 01 78 23 have extensive requirements for O&M’s and other items that are not pertinent to the SOW of this project.

Will these sections be revised?

These two spec sections are required to capture all product data for the installed hardware. Please see attached submittal register of required submittals that are necessary for this project marked with a "G".

Spec 01 78 24.00 10

01 78 24.00 20

Sections 01 78 24.00 10 & 01 78 24.00 20 do not fit the SOW or work being done under this contract. Will these sections be removed from the specifications?

The facility data sheet and facility data workbook are required for this project. The two forms will capture the two systems (the drainage ditch and the chain link fence) that are installed. The FDW will need to capture the field verified linear feet of each system that was installed. These forms are then used to update the government's asset databases.

At the site visit it was stated that orange snow fence was sufficient for temporary fencing per Security Forces. Please confirm that this is acceptable.

Yes, snow fence is acceptible for temporary fencing. When using temporary fencing attached controlled area signage as necessary to enclose and label the compound.

18 Spec 01 33 00

No submittal register has been provided and Section 01 33 00 speaks of it in the manner of a Design Build project not a Bid Build such as this. Can a submittal register be provided.

Please see attached Submittal Register for this project.

19 Spec 32 31 13.53

Section 32 31 13.53 is the only mention of concrete requirements and only list the required PSI at 28 days. There are no testing requirements or frequencies listed. Please clarify if concrete testing is needed or if just batch/delivery tickets showing the mix is 3,000 PSI or greater is sufficient.

Concrete testing will be required at 7, 14, 21, 28 days. Slump can go up to 8 with proper admixtures.

The SOW mentions surveying. Please clarify what is to be surveyed and if pre construction and post construction surveying is required.

Intent is to provide a positive drainge of the ditches in the intended direction of flow. A survey team is not required but the government will verify site conditions post construction.

At the site visit it was mentioned that some type of push bar should be installed on the inside of the single swing gate at the main entrance. Detail A1 on C-503 does not show this. Please provide the basis of design and any specs available from the manufacturer so that we can understand how to mount this on fencing fabric.

Provide a panic bar on the egress side of the gate with a lever handle that can be locked via key on the threat side. Per NFPA 101 panic bar heighth must be between 34"-48".

Use a 6035 DAC standard kit panic bar kit along with a DAC Door lever handle as basis of design or approved equal.

SOW 3.h.v calls for the installation of 4 inches of topsoil over disturbed areas with the exception of the rock access drive. Please clarify these areas with a new Key Note on the drawings for bidding purposes.
