Pre-Proposal Inquiries (PPIs) and Government Responses

1. Are there more details available for the specified epoxy with regards to physical properties and performance requirements as it pertains to chemical resistance, hardness, abrasion resistance, cure time, color, etc.?

GOVERNMENT RESPONSE:

UFGS 09 67 23.14

2.2.2.11 Chemical Resistance

ASTM D1308; no effect when exposed to the following reagents for 7 days:

Acetic acid: 5 percent solution Ammonium Hydroxide: 10 percent solution Citric Acid: 5 percent solution Coffee Cola Syrup Isopropyl Alcohol Mineral Oil Sodium Hydroxide: 5 percent solution

2. We are unable to find any information regarding application, specifically the finished thickness. Would this is be a rolled coating with a sand aggregate broadcast into the wet epoxy and top coated or would this be more of a troweled mortar system (3/16” – ¼” thickness) with a blended aggregate mixed into the epoxy?

GOVERNMENT RESPONSE: UFGS 09 67 23.14 Allows for 1/8” minimum for light duty traffic which applies to this area. Manufactures recommendations should be followed if thicker is required.

3. Is there a specific epoxy product manufacturer or manufacturers that the project specification is written around?

GOVERNMENT RESPONSE: No.

4. We noticed under STATEMENT OF WORK, IX. - Work Description: 6. that the specified color shall be grey. Would that be a light grey (such as concrete grey) or a dark grey (such as battleship grey)?

GOVERNMENT RESPONSE: IX. Statement of Work #6 states. Color shall be grey. Government shall chose specific color based on color samples provided by the contractor during submittal review.

5. We would like to know if this is a brand new contract OR if there is (was) an incumbent performing these services. If not brand new, could you please provide the current / previous contract number?

GOVERNMENT RESPONSE: This is a new requirement. There is not an incumbent or current/previous contract number.

6. I read in the solicitation that only Washington contractors with a license only. Can we compete for this project [if we are not licensed in WA]?

GOVERNMENT RESPONSE: OFFEROR MUST BE A LICENSED WASHINGTON STATE

CONTRACTOR.

7. Contract drawing has note to replace metal grating with Fiberglass grating. However, no size for this grating is found in contract documents nor is any spec found. Please provide dimensions for this grating along with spec section got fiberglass grating.

GOVERNMENT RESPONSE: Existing metal grating is approximately 1” thick. The trench is approximately 15” wide with a larger 39”x39” section in the middle. See photos and drawings in the solicitation. All dimensions should be field verified by the contractor.

8. Contract documents call for contractor to clean floor / sump and apply new epoxy costing. No spec is found for new epoxy coating to be applied. Please provide spec for epoxy product.

GOVERNMENT RESPONSE:

UFGS 09 67 23.14

2.2.2.11 Chemical Resistance

ASTM D1308; no effect when exposed to the following reagents for 7 days:

Acetic acid: 5 percent solution Ammonium Hydroxide: 10 percent solution Citric Acid: 5 percent solution Coffee Cola Syrup Isopropyl Alcohol Mineral Oil Sodium Hydroxide: 5 percent solution

9. Would the Government prefer fiberglass grating “VICOR” which is more resistant to corrosive situations (from caustic to acidic) which is a long lead item verses standard “CORVEX” which is readily available?

GOVERNMENT RESPONSE: “VICOR” or more corrosive resistant grating is not necessary.

10. It was observed that the chemical tanks contain 50% Nitric, 22% Sulphuric, or Caustic Soda, and can be at elevated temperatures. Is it required to have a high quality Novolac Epoxy at minimum 60 mils resin thickness that can better withstand these exposures?

GOVERNMENT RESPONSE: Our chemical engineer does not feel it is necessary to provide Novolac Epoxy. See answers 1 and 8 for epoxy requirements.

11. Will the tankline be in operation during the surface preparation and the installation of the coatings? If not, what will be the duration of downtime available?

GOVERNMENT RESPONSE: Tank line will not be down the entire period of performance of this contract. Coordination with the building occupants will be required but downtime is possible with advanced notice to maintain mission essential work but not be more than 2 weeks at a time. Request for downtime should be limited to necessary evolutions like surface prep when plastic is in place and dust is being generated that could impact operations or worker safety. When tank line is operational and contractors are working, coordination and daily communication will take place to assure both contractor and government personnel are in safe working conditions.
