Questions and Answers – WWVH Government Property Relocation

1. In the generator room, there are metal pipes on the ceiling that appear to be blocked off (as shown in the site visit photos). Will these need to be relocated as part of the project scope?

Yes these items (antenna feeds) are within scope. It is permissible to remove a Uni-strut hangar to facilitate removal of the antenna feeds.

2. Will on-site dumpsters be available for use, or should we plan to provide our own dumpster for debris removal?

Contractor to provide their own on-site dumpster(s) for debris/trash removal.

3. Do all three storage units require HVAC (A/C) and electrical service?

Only 1 container will be conditioned, equipped with HVAC and provided an Electrical connection. Two of the containers are to be unconditioned with no electrical connection.

4. Regarding the timeline for moving services, will this be a one-time move or phased over a period of time?

The intent is to relocate the government property from the premises to the storage containers as a one-time move. At the conclusion of the construction project the government property is to be moved back into the facility as a one-time move.

5. Will the Government identify and label which items or areas require access versus those that should not be accessed?

Government will identify which items inside the facility are to be relocated. Government will also identify which items (spare parts) should be moved into the Conditioned storage container.

6. Relocation Scope of Work (Government Property) - Kindly confirm that the following scope is correct:

1. Move government lab & transmitter equipment from:

1. Buildings 800 & 800A

2. Surrounding grounds This is correct.

PAGE 4 OF 7 1333ND26QNB1902490001

2. Place items into containers This is correct, also disposal of debris/trash removal.

3. Please specify the number of lab and transmitter equipment units that need relocation.

(4) FRT-96 transmitters ~1700 LBS to conditioned container (1) Elcom Bauer transmitter ~ 1200LBS to shop area.

7. End of project:

1. Move everything back into buildings

2. Follow NISTstaff instructions for sensitive equipment This is correct, plus the items listed in Question 8

8. Delivery & Labor Support Requirements- Please confirm the type of equipment required for site work (e.g., forklift, crane, or container mule).

Contractor to coordinate equipment required for container delivery with container supplier recommendation and location of conditioned container. Type of equipment needed will most likely depend on where the conditioned container is positioned.

Supplemental information on container positioning- If conditioned container needs to be placed differently than outlined on the 01C WWVH Site Plan, contractor will need to coordinate delivery route of containers and container positioning around existing underground antenna feeds. Antenna feeds are buried less than 2’ in the ground and should not be driven over without ground protection. Refer to attached supplemental document WWVH Antenna Field Site Plan for approximate locations of buried antenna feeds.

For relocating government property: contractor to furnish all equipment and labor to relocate government property as outlined in the contract documents.

Additionally, kindly confirm required labor scope, including:

1. Remove all containers

2. Return containers to supplier

3. Remove electrical connections

4. Patch and restore building penetrations

5. Restore landscaping and site condition

This is correct. Contractor will also be responsible for installing all of the items listed above including coordinating/installing the electrical power connection to the conditioned container during container delivery.

9. One (1) 40' conditioned container: Please confirm if you require a 40' Contractor’s Office. For reference, we have included inclusions and a video walkthrough below:

Video walkthrough (open hyperlink for video container walk through)

The Container in the video would be sufficient, but this has more accessory equipment than is needed. The conditioned container only needs to have power connection and HVAC controls and will not be occupied. No windows are required. A personnel door would be convenient. container needs to be able fully open at one end similar to the container in the video. Finished floor is not recommended.
