d) Answers to questions received

1. How are material substitution requests going to be handled?

Response: The Government will not review material substitution requests prior to solicitation due date. Consistent with FAR Clause 52.236-5, the specifications establish a standard of quality and shall not be construed as limiting competition. The Contractor may, as part of the post award material approval process, submit for consideration and approval by the Contracting Officer, any equipment, material, article, or process the Contractor feels is equal to that specified, however, the burden of establishing "equal" rests solely upon the Contractor. The Government will in no way be responsible for any additional costs a Contractor may incur for having to resort to other equipment, materials, articles, or processes for submittals found by the Contracting Officer not to be equal to that specified.

2. Section 123110 and Section 123553.19 (Attachment J-2) seem to be duplicated. Sheet A-701 (Attachment J-1), G and J of the Code Legend reference Metal Casework Section 125650 1.08 (Attachment J-2) references that casework, fittings and workstations come from same manufacture. Is casework to be plastic laminate or metal in the labs? Is Mobile casework to be plastic laminate or metal? If casework is to be plastic laminate, is 12 35 53.19 to be used for the laboratory casework? If casework is to be plastic laminate, will 125650 1.08A be stricken?

Response: Spec 123110 and 12355.3.19 are for the furniture systems in the offices, and break rooms i.e. anything that is not in a lab. Section 125650 specifically refers to Laboratory furniture system, casework, work surfaces, and accessories. We do not want to receive the benches from one manufacturer and the lab case work from another.

3. Section 12 56 50 (Attachment J-2) and sheet A-701 (Attachment J-1) detail the DT19 and CT19 units. The units show the 84” tall nominal units with shelving and apparent electrical wiring.

Most of the elevations (A700 Sheets) call out the DT19 and CT19 units, but show a different unit.

Are the units to be provided as specified and detailed on A701or as shown on the elevations?

Response: As specified and detailed on A701 (DT19 and CT19 units).

4. There are 2 Compressed Air Specifications 221500 General Service Compressed Air, and 226006 (Attachment J-2) Process Laboratory Piping Systems. Which specification is to be used for the CA serving the labs in Bldg. 14?

Amendment 5 15-223-SOL-00107 2 of 15

The detail for this is found on sheet M501, Detail 9.

9. There are multiple references to Phase 1 "A" & Phase 1 "B". Are these to be included in Phase 1 Pricing?

Response: Phases 1'A" and 1'B" are a part of phase 1. This is intended to show sub phasing.

10. M 2.2—this is noted ph 2, is this to be bid as phase 2 or opt 1—opt 1 says all of second floor?

Response: This should be bid as Option 1 CLIN 3. If this option is exercised, construction will commence during Phase 2 construction.

11. M4.2 (Attachment J-5)- noted as phase 2, but plans call for duct on second floor to be option 1.

Response: This should be bid as Option 1 CLIN 3. If this option is exercised, construction will commence during Phase 2 construction.

12. M113 (Attachment J-1)—keyed note 9 has two arrows, but note states existing ventilation fan and platform shall be demolished. Is there more than one fan/platform at this location

Response: There is one fan and the platform to access it is in this area.

22. See below for one-line. Should the new service (highlighted in yellow) be included in Phase 1?

Also, if all of the ATS's were in phase 1, the start-up on the generator/ATS's could possibly be done at one time, to eliminate an added cost for two "start-up" fees from the generator supplier.

Response: The installation methods are up to the contractor as long as they meet the NCTR facilities direction. It is acceptable to be included in Phase 1 if the contractor can make it work without significant shut downs to Building 14 East.

23. Please clarify that it is the intent for ALL panel feeders to be installed in Galvanized rigid Conduit. (Attachments J-2, and J4)

Response: Yes, all panel feeders. 26 05 34 2.01 N Panelboard feeders: Use galvanized steel rigid metal conduit.

24. Panel HDE on E-602 missing panel schedule (Attachment J-1)

Response: Panel HDE on E-602 should not be included in the bid; it has been eliminated and will not have a panel schedule.

25. Section 115300 (Attachment J-1) calls for all Laboratory Service Fittings and Emergency Equipment to be supplied by same manufacture and from same supplier. 2.02, A, B & C call for recessed type safety equipment. Plumbing drawings are calling out a completely different unit onP-501 and P-601.Who is to supply safety equipment, and which specification should be followed? If 115300 is to supply safety equipment, do we also provide the Thermostatic mixing valves?

Response: The equipment on the drawings are correct. No recessed emergency fixtures are to be used. The mixing valve is to be provided by whomever provides the emergency equipment.

26. Plumbing - The plumbing schedule on P-601 and sheets P-103 and P-104 (Attachment J-1) are in conflict with the Laboratory Specifications. For example, fume hoods are called out to have cold

Amendment 5 15-223-SOL-00107 5 of 15 water, gas, air, and vacuum in the specifications but only show cold water hook-up on P-103 and P-104. The sink schedules on P-601 have plumbing contractor providing non laboratory grade fixtures at lab sinks while lab fixtures are also called out in section 1153 00. The workstations called out in 12 56 50 do not have any indication of gas connections. Please provide clarification on laboratory plumbing.

Response: The only connections to the fume hood that the contractor is responsible for are the cold water connections. The lab gas connections will be completed by the owner and their own contractor. All fixtures in labs are to be lab grade. The only plumbing fixtures in the labs are the sinks with a DI faucet, a manual faucet, and an eyewash/drench hose. These need to be lab grade.

27. The existing structure on Building 14 shows some signs of weathering. Can we provide recommendations for repair?" Refer to attached photo.

Response: From the photo the corrosion looks superficial. . Recommend removing any soil/top soil form contacting the steel column surface. Clean surface of steel. Prep and paint bottom of column with primer and paint. The [building 14 addition] new slab turndown will encase the existing rigid frame column base below finish floor elevation

28. Will the Fire Alarm / Mass Notification Panel for Building 14 be networked with the other existing Fire Alarm / Mass Notification Panels at the site?

Response: Yes, panels will continue to be networked back to Building 54 existing Siemens system.

29. Drawing F 502 (Attachment J-1), in the upper left corner, shows the NAC Circuits to be Class “A”.

Section 28-31-00 of the Specifications, paragraph 2.02 “C“states NAC circuits to be Class ”B”.

Please clarify.

34. (Bldg. 53A) M-408—detail 5—bldg. 14 (Attachment J-3)--some sort of (plastic scrim), we did not do bldg. 62, nor was it included in the walk thru—we can find no vendor that has any type of plastic scrim with labeling for it, if this is what you want, we need a spec with a vendor name, a supplier of this product, nothing on internet either---scrim is defined as a gauze, not plastic on internet, and nothing with printing?

Response: The detail calls for a four foot PVC section. This should be changed to a 6 foot section consisting of 20 mill aluminum jacketing. Provide preform elbows where required. The jacketing is to protect the ductwork from wear and tear in the areas used by maintenance personnel.

35. (Bldg. 53A) M-408 bldg. 14—detail 7—gen note 2 (Attachment J-3)—the drawings says refer to the structural for the duct supports, I do not see these shown on the structural, is the intent for this metal to be included under the structural, or mechanical, it shows in neither division?

Response: Using the detail on M-408 (detail 7) we would encourage the contractor to work with the unistrut company to determine a good solution using clamps or screws to connect the unistrut to the joist. Contractor shall submit shop drawings of proposed support system for duct work to structural engineer for approval.

36. (Bldg. 53A) M-501—bldg. 14—detail 6 (Attachment J-3)—shows trapeze hangers for all duct below 36 inches diameter, this is not a SMACNA mandate, is this the engineers mandate? If so, is this to be used on all the small ducts, 6x6, 6 inch round?—what is the intent for the use of

Amendment 5 15-223-SOL-00107 7 of 15 these trapeze hangers for small ducts? Does this also apply to bldg. 53?

Response: Upon review, we agree that this is not the right approach. The right approach is to apply 20 gauge metal panel system. Please find the attached pdfs of drawings and specs for the revision. Below is a summary of the architectural revisions that were made. (Attachment J-1)

• Omit specification section 09 98 50 'SPRAYED ENCAPSULATE COATING'

• Add specification section 07 42 13 METAL PANELS

• Issued Revisions to Sheets: A-104, A-105, A-601, A-602

• All areas previously noted to have exposed ceiling/structure with sprayed encapsulate coating shall now receive a pre-finished metal ceiling panel as indicated on the revised drawings and specifications. See attachment 3 (9 pages).

Response: There is no requirement for Stainless Steel or PVC coated duct work for Buildings 14 or 53A.
