QUESTIONS AND ANSWERS FOR

SOLICITATION W50S8Z-20-B-0001

Construct Corrosion Control Facility Project No. KJAQ119006

Updated: 15 Jan 2020

Date: 6 Dec 2019

RFI Question 1: Is there a possibility of moving the bid date to late January? The upcoming holidays will greatly impact our ability to get subcontractor pricing in time for a 6 January 2020 bid date.

Answer 1: New bid due date is 23 Jan 2020.

Date: 10 Dec 2019

RFI Question 2: The end of year timing of this highly complex project will reduce participation among subcontractors, many of which are not in the office for the holiday season. As such, it will be difficult to obtain competitive pricing from all of the different trades by 6 January 2020. In order to obtain the most competitive and accurate pricing, we strongly recommend extending the close of the solicitation to 27 January 2020.

Answer 2. SEE Response to RFI 1.

Date: 11 Dec 2019

RFI Question 3: Coiling doors Section 08 33 23. For doors 127A, 125B, 123B, 123D, 123E. The door schedule indicates these to be lead lined, but plans and spec indicates otherwise. Please Confirm that the spec is accurate showing 18 ga. Galvanized steel curtain

Answer 3. See Spec section 13 49 10 – 2.7 refers to Lead-lined doors and frames. These doors (127A, 125B, 123B, 123D, 123E) shall be ATFP rated and insulated, NOT to be lead lined. Curtain and hanging systems are to be in place at doors 123B, D and E.

Date: 13 Dec 2019

RFI Question 4: We are planning to bid section 33 32 16 Package Utility Wastewater Pumping Stations.

There are no flow or discharge pressure requirements listed. Are there any available?

Answer 4. Detail 4 on project plan sheet C-502 identifies the use of 1hp pumps. Both pumps are 1hp, either 120v or 240v. Attached to this RFI response is an example packaged grinder pump station, an approved equal may alternatively be used. The packaged system pumps are per the manufacturer in accordance with section ‘33 32 16 – 2.3 Pump Motor’.

Sewage flow calculations are attached (Attch 1). Explosion proofing requirements identified under 33 32 16 section 2.2. The E/one example contains discharge pressures and associated flows.

Grinder pump working pressure requirements are outlined in 33 32 16.

Date: 19 Dec 2019

RFI Question 5: Will the government please identify the significant changes to specifications that were made in the determination to re-solicit the Corrosion Control Hanger? With over 2000 pages of specs/drawings and to provide full transparency, at minimum, please cite the Divisions and Sections where these changes can be identified and addressed.

RFI Question 7: Option 4 Lead lining on the hanger, does the lead extend to full height of the hanger walls?

Answer 7. Yes. Lead lining extends to the full height of the hangar walls.

Date: 20 Dec 2019

RFI Question 8: Is there a detail showing how the lead lining is to be attached to the hanger siding and columns?

Answer 8. Detail 03/A-141 shows detail of exterior wall with lead lining. Since the columns are interior to the lead-lined wall panels they will not need to be wrapped in lead. The lead lining can be overlapped as in the detail or butt joined with a 2” strip of lead covering the butt joint. Section 13 49 10, describes the method of attachment.

Date: 20 Dec 2019

RFI Question 9: Per SECTION 13 49 10; Item 3.2 LEAD-LINED PANELS States, “Lead-lined panels shall be butt-jointed and shall be placed over supports with lead linings placed next to supports.”

a. Where does this condition exist and what detail will reflect this?

b. All details in sheets A-501, A-502, A-503 and A-504 only reflect either lead sheet or lead lined GWB.

Answer 9. a. Detail 1/A-142 (At Gypsum Board Joints) show the lead applied to the support and the gyp butt jointed forward of the stud.

b. Is there a question here?

In general, there will need to be an overlap where any joints occur. There can be no avenue for x-rays to penetrate the wall system.

Date: 20 Dec 2019

RFI Question 10: Per SECTION 13 49 10; Item 1.5 WARRANTY; States, “Lead sheet shielding materials shall be warranted against sagging and curling for 10 years.” Many aspects of the shielding are components of assemblies around columns and other obstacles, are integrated into field applied systems, or are applied to premanufactured products. Per 07 42 63 FABRICATED WALL PANEL ASSEMBLIES there is no information or reference to the lead sheets which means this is all field applied and the integrity is in the means of attachment directly to the insulated metal wall panel.

a. Is the warranty a workmanship or performance warranty?

Answer 10. This is a workmanship warranty.

Date: 20 Dec 2019

RFI Question 11: Please provide or verify the exterior insulated wall panel gauge (interior skin & exterior skin) and finish (SMP or Kynar), as well as the liner panel gauge
