RFI`S

1. Can a detour be made through the grass area when doing road work?

Response: Detours are not to be planned in order to maintain traffic flow. Contractor shall follow guidance in Section 01 11 00, paragraph 1.6, Coordination with CRREL Traffic.

2. Will the contractor be required to address a water drainage/infiltration through the conduit into the building?

Response: Due to the elevation differences between the electrical manholes and where electrical ducts or conduits enter buildings, there is potential for water to infiltrate the buildings through them. As such, based upon the conditions found, the contractor shall furnish and install an in-ground solution that will permit drainage of any water in the ducts or conduits before it reaches the buildings. Contractor shall provide shop drawings to the Government for approval prior to beginning work on this feature. Ducts or conduits entering an exterior wall shall slope away from the wall. Contractor shall provide waterproof seals around all ducts or conduits penetrating an exterior wall.

Contractor shall also seal all ducts or conduits themselves at the inside face of the exterior wall.

3. What are the depths of the storm water drains and feeders?

Response: Specification 33 71 02 UNDERGROUND ELECTRICAL DISTRIBUTION Paragraph 3.1.1 UTILITY LOCATE, and Specification 01 35 26 GOVERNMENT SAFETY REQUIREMENTS Paragraph 3.7.1 UTILITY LOCATIONS, and Paragraph

3.7.2 UTILITY LOCATION VERIFICATION, addresses this question. The contractor is responsible for determining the exact locations of utilities within the general area of excavation.

4. What utilities are in the additional man hole marked electrical?

Response: The exact feeders and routing of the distribution within the manhole in vicinity of the proposed main lab addition penetration is unknown at this time. Please also reference Specification 33 71 02 UNDERGROUND ELECTRICAL DISTRIBUTION Paragraph 3.1.1 UTILITY LOCATE, and Specification 01 35 26 GOVERNMENT SAFETY REQUIREMENTS Paragraph 3.7.1 UTILITY LOCATIONS, and Paragraph 3.7.2 UTILITY LOCATION VERIFICATION

5. Can an additional man hole be created for utilities?

Response: See Changes to specification 33 71 02 UNDERGROUND ELECTRICAL DISTRIBUTION in Amendment 001. Contractor shall bid based upon plans and specifications in the most updated contract documents. However, if a contractor wants to install an extra manhole as part of its means and methods, at no additional cost to the Government, this issue can be addressed with a RFI during construction.

6. During basement demolition, does all demolished equipment needs to be able to fit through the existing door way.

Response: Yes, all materials need to fit through the existing doorway and out of the facility to be disposed of.

7. What is the age of existing equipment to be demolished and is there asbestos present in that equipment?

Response: The equipment was installed in the 1960s. Though not confirmed, contractors should expect the equipment to include asbestos or asbestos-containing material.

8. Will basement wall drawings be provided to the contractor?

Response: Drawings will not be provided. Basement exterior walls in the main lab addition in vicinity of the conduit entrance as depicted on Sheets ES101 and EP102 are constructed of approximately 1’ thick reinforced concrete.

9. What is the structural integrity of basement walls?

Response: See wall specifications provided per the response to RFI 8.

10. What will be the path of equipment considering the low points and narrow pathways?

Response: It is the contractor’s responsibility to determine the best way to install and remove equipment inside the facility. The contractor shall coordinate with the COR to determine the safest route to move equipment through the building.

11. Is there PCB and/or TCE contamination?

Response: Please see Section 01 35 26, paragraphs 1.6, Trichloroethylene TCE), and 1.7, Polychlorinated Biphenyls (PCBs). Note, regarding PCB testing of the transformer oil, all results for the oil-filled transformers were less than 10 ppm.

12. Do the transformer room columns need to stay in place or can they be removed?

Response: All columns in the transformer rooms shall stay in place undisturbed.

13. What kind of oil is in the oil-filled transformers?

Response: R-Temp fluid is the oil used inside of existing oil-filled transformers.

14. Will the power be shut down before working on the electrical systems?

Response: Please see Section 01 35 26, paragraphs 1.16, Hot Work, 3.2, Pre-Outage Coordination Meeting, and 3.3, Control of Hazardous Energy (Lockout/Tagout).

15. What toxic substances are expected to be present during this project?

Response: The term “toxic substances” is very broad. Many commonly used construction products can be toxic depending on exposure (e.g. Portland cement). Please see Section 01 35 26, Government Safety Requirements. Also, please see responses to RFI #7 and RFI #11.

16. Is there a requirement for National Cable Splicing Certification?

Response: Cable splicers must meet the requirements of 26 05 13.00 40. National Cable Splicing Certification is not required.

17. What will be the equipment path for the transformer room?

Response: See response to RFI #10.

18. What are the existing ceiling hanger ratings?

Response: The ratings of existing ceiling hangers inside the facility are unknown. Use or reuse of existing ceiling hangers is not permitted unless the contractor can definitively show compliance with the specifications and plans.

19. Will this project be allocated more time due to time needed to procure equipment?

Response: Please see clause 52.211-10 and Amendment 001.

20. What is behind the drywall near the transformer room and what is the drywall rating?

Response: The fire ratings of the actual wall assemblies are unknown. As such, seal all wall penetrations with an intumescent firestop material with a minimum two-hour fire rating formulated to bond to concrete, metals, wood, plastic and cable jacketing.

21. Can Radar be used to locate conduit in the ceiling prior to the placing/setting of ceiling anchors?

Response: This method is acceptable if the contractor chooses to do this.

22. Is there a fire sprinkler system in place?

Response: There is no fire sprinkler system in the basement level.

23. What will be the location of a construction staging area and refuse location?

Response: Please see Section 01 50 00 TEMPORARY CONSTRUCTION FACILITIES AND CONTROLS, Paragraph 1.4 CONSTRUCTION SITE PLAN regarding the construction staging area and SECTION 01 74 19 CONSTRUCTION AND DEMOLITION WASTE MANAGEMENT for a discussion on the disposal of refuse for the project. The construction staging area and refuse location shall be coordinated at the pre-construction meeting.

24. Drawing EP601 shows two breaker in parallel for each LV feeder, is this correct?

Response: The drawing is correct. The intent of the design is provide a dual breaker switchgear to allow maintenance on the breakers without interrupting the load.

25. Drawing EP601 and EP606 show feeder LV-1 as 3 sets of 600MCM + 3/0 gnd (approximate ampacity of 1300A) connected to 1600 AT breaker. Is this correct?

Response: The feeder is replacing the 750 kVA transformer that will be demolished. The full load current of a 750 kVA transformer is 902A. The new feeder is a 1200A feeder increasing the capacity of the equipment while remaining within the equipment's rating.

The drawing is correct.

Note: Executive Order (EO) 13706, Establishing Paid Sick Leave for Federal Contractors applies to all contracts subject to the Davis‐Bacon Act for which the contract is awarded (and any solicitation was issued) on or after January 1, 2017. If this contract is covered by the EO, the contractor must provide employees with 1 hour of paid sick leave for every 30 hours they work, up to 56 hours of paid sick leave each year.

Employees must be permitted to use paid sick leave for their own illness, injury or other health‐related needs, including preventive care; to assist a family member (or person who is like family to the employee) who is ill, injured, or has other health‐related needs, including preventive care; or for reasons resulting from, or to assist a family member (or person who is like family to the employee) who is a victim of, domestic violence, sexual assault, or stalking. Additional information on contractor requirements and worker protections under the EO is available at www.dol.gov/whd/govcontracts.

Unlisted classifications needed for work not included within the scope of the classifications listed may be added after award only as provided in the labor standards contract clauses (29CFR 5.5 (a) (1) (ii)).

The body of each wage determination lists the classification and wage rates that have been found to be prevailing for the cited type(s) of construction in the area covered by the wage determination. The classifications are listed in alphabetical order of "identifiers" that indicate whether the particular rate is a union rate (current union negotiated rate for local), a survey rate (weighted average rate) or a union average rate (weighted union average rate).

Union Rate Identifiers

A four letter classification abbreviation identifier enclosed in dotted lines beginning with characters other than "SU" or "UAVG" denotes that the union classification and rate were prevailing for that classification in the survey. Example:

PLUM0198‐005 07/01/2014. PLUM is an abbreviation identifier of the union which prevailed in the survey for this classification, which in this example would be Plumbers. 0198 indicates the local union number or district council number where applicable, i.e., Plumbers Local 0198. The next number, 005 in the example, is an internal number used in processing the wage determination. 07/01/2014 is the effective date of the most current negotiated rate, which in this example is July 1, 2014.

Union prevailing wage rates are updated to reflect all rate changes in the collective bargaining agreement (CBA) governing this classification and rate.

Survey Rate Identifiers

Classifications listed under the "SU" identifier indicate that no one rate prevailed for this classification in the survey and the published rate is derived by computing a weighted average rate based on all the rates reported in the survey for that classification. As this weighted average rate includes all rates reported in the survey, it may include both union and non‐union rates. Example: SULA2012‐007 5/13/2014. SU indicates the rates are survey rates based on a weighted average calculation of rates and are not majority rates. LA indicates the State of Louisiana. 2012 is the year of survey on which these classifications and rates are based. The next number, 007 in the example, is an internal number used in producing the wage determination. 5/13/2014 indicates the survey completion date for the classifications and rates under that identifier.

Survey wage rates are not updated and remain in effect until a new survey is conducted.

Union Average Rate Identifiers

Classification(s) listed under the UAVG identifier indicate that no single majority rate prevailed for those classifications; however, 100% of the data reported for the classifications was union data. EXAMPLE: UAVG‐OH‐0010 08/29/2014. UAVG indicates that the rate is a weighted union average rate. OH indicates the state. The next number, 0010 in the example, is an internal number used in producing the wage determination. 08/29/2014 indicates the survey completion date for the classifications and rates under that identifier.

A UAVG rate will be updated once a year, usually in January of each year, to reflect a weighted average of the current negotiated/CBA rate of the union locals from which the rate is based.

WAGE DETERMINATION APPEALS PROCESS

1.) Has there been an initial decision in the matter? This can be:

* an existing published wage determination

* a survey underlying a wage determination

* a Wage and Hour Division letter setting forth a position on a wage determination matter

* a conformance (additional classification and rate) ruling

On survey related matters, initial contact, including requests for summaries of surveys, should be with the Wage and Hour Regional Office for the area in which the survey was conducted because those Regional Offices have responsibility for the Davis‐Bacon survey program. If the response from this initial contact is not satisfactory, then the process described in 2.)

and 3.) should be followed.

With regard to any other matter not yet ripe for the formal process described here, initial contact should be with the Branch of Construction Wage Determinations. Write to:

Branch of Construction Wage Determinations Wage and Hour Division U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

2.) If the answer to the question in 1.) is yes, then an interested party (those affected by the action) can request review and reconsideration from the Wage and Hour Administrator (See 29 CFR Part 1.8 and 29 CFR Part 7). Write to:

Wage and Hour Administrator U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

The request should be accompanied by a full statement of the interested party's position and by any information (wage payment data, project description, area practice material, etc.) that the requestor considers relevant to the issue.

3.) If the decision of the Administrator is not favorable, an interested party may appeal directly to the Administrative Review Board (formerly the Wage Appeals Board). Write to:

Administrative Review Board U.S. Department of Labor 200 Constitution Avenue, N.W.

Washington, DC 20210

4.) All decisions by the Administrative Review Board are final.

END OF GENERAL DECISION

The following have been modified:

52.211-10 COMMENCEMENT, PROSECUTION, AND COMPLETION OF WORK (APR 1984)

The Contractor shall be required to (a) commence work under this contract within 15 calendar days after the date the Contractor receives the notice to proceed, (b) prosecute the work diligently, and (c) complete the entire work ready for use not later than 365 DAYS The time stated for completion shall include final cleanup of the premises.
