Statement of Work Site wide transformer fluid analyses Base year and four option year General Background National Institute of Standard and Technology (NIST) is a non-regulatory federal agency of Department of Commerce. NIST’s goal is to promote innovation by advancing measurement science, standard, and technology. NIST Power distribution system starts with three (3) 13.8 KV incoming feeders from PEPCO that feeds the 13.8 KV Main Substation in Building 306. The main substation provides power distribution to all Buildings in the campus via stepped down 13. 8KV:480V liquid filled transformers.

NIST has a requirement to test the insulating fluid of all liquid filled transformers as recommended per NFPA 70B. NIST originally was equipped with Askerel filled transformers (appr. 95 units), ranging from 300 KVA to 2000 KVA, distributed to 22 Buildings. All the original transformers were retro-filled with Silicone dielectric fluid. The original Askerel transformers were then reclassified as non-PCB transformers with PCB concentration of less than 50 ppm. Many retro-filled transformers have been replaced with new non PCB liquid filled transformers (Silicone, FR3, Bio-temp). There are approximately 36 retro-filled transformers to remain. All remaining retro-filled transformers shall be tested for PCB concentration.

NIST has a requirement for testing of transformer oil for all transformers. The Contractor shall collect oil samples and perform oil analyses including Quality Oil Analyses, Dissolved Gas Analyses (DGA). and PCB (PCB test for retro-filled transformers) objective The NIST intends to award a contract to a transformer service provider, to provide transformer visual inspection, transformer oil sampling and oil analyses for all liquid filled transformers at National Institute of Standards and Technology (NIST) facility in Gaithersburg, Maryland. The transformer inspection and transformer oil testing helps mitigate the risks of arc flash, component failure, structural fire, and electric shock.

Scope of work The Contractor shall be responsible for providing all required management, labor, materials, equipment, tools, protective equipment, and other items needed to accomplice the work described in this solicitation. All work shall be in conformance with the requirements of the contract and manufacturer recommendations. All work shall be in compliance with Federal, State, and Local requirements, as well as OSHA 1926 Safety and Health Regulations for Construction.

General Requirement

a. Apply Badging for site access.

b. Provide Activity Hazard Analyses (AHA). Submit AHA for approval prior to Notice to Proceed. (NTP).

c. Provide a written report with the transformer visual inspection and transformer oil analyses, and to provide recommendations. The testing report shall be arranged and listed according to the building number.

Use of Site: Limit use of premises to areas within the project area. Do not disturb portions of Project site beyond areas of work.

Driveways and Entrances: Keep driveways and entrances serving premises clear and available to Owner’s, and emergency vehicles at all times. Do not use these areas for parking or storage of materials. Schedule equipment pickup or delivery to minimize disruption of traffic in driveway and entrances.

On-Site Work Hours: Work shall be generally performed inside the existing building during normal business working hours of 7:00 a.m. to 5:30 p.m., Monday through Friday, except otherwise indicated. Coordinate with COTR to suit Owner’s requirements.

Weekend Hours: No work is allowed during weekends, except with permission from COTR.

Early Morning Hours: Same as above.

Hours for Utility Shutdowns: After regular hours with permission from COTR.

Contractor shall follow the: Guidelines for Contractors and A/E Firms Performing Site Investigations and Fieldwork at National Institute of Standards and Technology Gaithersburg, MD” when it is conducting site investigation and field work.

Hazardous waste under this contract shall be properly secured at all times in accordance with applicable Federal, State, and Local as well as NIST specific requirements. Under no circumstances shall carts and vehicles containing hazardous waste left unintended unless they have left in an appropriate, locked, secured, location.

Existing Utility Interruptions: Do not interrupt utilities serving facilities occupied by Owner or others unless permitted under the following conditions.

Notify COTR not less than fourteen days in advance of proposed utility interruptions.

Do not proceed with utility interruptions without COTR’s written permission.

Arrange a meeting with COTR to discuss the consequences of the interruption of the utilities.

Badging: Due to security requirements, NIST requires each individual working on this contract to have a background check and receive a NIST green badge, which allows them unescorted access on the NIST campus. The contractor shall submit badging application forms within 10 business days after award of the contract. Once the badge application is accepted, each individual will be required to get fingerprinted either at NIST or an approved location, and also complete an online questionnaire for a background investigation called eAPP. Once everything is approved, each individual will be required to go back to the badge office and pick-up their badge and sign paperwork. This process should take about 60 days to get officially badged if individuals are timely in getting fingerprinted and filling out the eAPP.

Additional documents will be needed if the applicant is not a US Citizen. If the applicant is a Permanent Resident, they will need to submit a copy of their Permanent Resident Card (a.k.a. Green Card). If the applicant is in the U.S. on a work visa, they will need to submit a completed NIST-1260 form and a copy of their passport.

All badge applications, attachments, and additional documents must be emailed securely to the COR via the NIST Secure File Transfer system. Contact the COR when you are ready for this service.

Security:

NIST is a Federal facility and access is controlled at all entrances to the campus. Only Government employees may grant access to non-Government employees. All non-Government employees must be registered with security prior to site access. Contractor must notify COR a minimum of 48 hours prior to site access. Contractor must provide COR with first and last names, country of citizenship, and whether the individual has a permanent resident card, (a.k.a. Green Card), of all personnel requiring site access. If any individuals are here on a work visa, they will need to complete a NIST 1260 form and return to the COR. Please refer to the following web site for additional Visitor Information http://www.nist.gov/public_affairs/visitor/

Automobile & Personnel Access:

Contractor personnel arriving in cars on their first day must check in at the visitor center to receive a temporary paper badge prior to proceeding to the project site. Hours of operation of the visitor center are 0600-1700. Once in possession of a valid NIST badge, workers may enter via the Main Gate or Gate “C” and proceed to the project site. Note that all automobiles are subject to a random inspection.

No deliveries will be allowed after 4:30 pm. “Trucks” include such vehicles as pick-ups with storage compartments, delivery trucks, delivery vans, and tractor center. Trucks arriving through Gate F will be directed to Truck Inspection Station. At Inspection Station, trucks will be registered, inspected, and the drivers will be granted access. Any truck which exits the installation will have to be re-inspected upon re-entry at Inspection Station. A vehicle dashboard placard will be placed within the truck. Placards change daily.

Parking: Parking is restricted to areas adjacent to the lay-down area. Short term parking is permitted at building loading dock areas to facilitate unloading and loading of material. Fifteen feet of clearing shall be maintained around all fire hydrants.

Public Release of Information: The Contractor shall not publicly release information, photo, or other document and items concerning any aspect of the materials or services pertaining to this contract without the prior approval of the COTR.
