SUMMARY OF CHANGES

SECTION SF 30 - BLOCK 14 CONTINUATION PAGE

The following have been modified:

REQUEST FOR INFORMATION

QUESTION 1: The specifications call for complete removal of existing coatings through abrasive blasting, which is achievable, but the word complete could result in more damage of the concrete substrate than required to blast off adherent coatings. Please confirm that the intent is to remove all coatings (adherent and non-adherent) from the concrete substrates.

RESPONSE 1: “Complete” removal of paint on concrete is not a requirement. Interested vendors are directed to the requirements stipulated in the Statement of Work paragraph A.2.a bullet #1, paragraph A.2.b, paragraph A.2.j and k. The intent is to remove as much of the existing coatings as possible. The Technical Point of Contact should be consulted in areas of uncertainty. Any damages to the concrete as a result of paint removal shall be repaired by the Contractor.

QUESTION 2: What is the existing coating system and thickness?

RESPONSE 2: The gallery, floors, stairs, and lower basement are currently painted with approximately one or two coats of paint. The exact paint type is unknown. Visual observation of the existing paint does not indicate it to be thick layer of coating like Tnemec or equivalent.

QUESTION 3: There is not a steel coating system referenced in the 09 97 02 spec section and the only surface preparation is SP-1. Please advise on a steel/ferrous metal coating system.

RESPONSE 3: Salient characteristics for epoxy primer/sealer for steel/metal coating is called out on Specification Section 09 97 02, paragraph 2.1 and all its sub-paragraphs.

QUESTION 4: The summary for 09 97 02 spec section has all included stair railings, stair nosing, floor drain grates and fames, floor covering plate and frames, and related items. Please provide more details and/or quantities of these ferrous steel items as there are no limits or quantities provided in the solicitation.

RESPONSE 4: The metal items are called out in the as-built references TH-1-1304 and TH-1-1306. The metal items included are only within the gallery and lower basement work areas as described in the scope of work. The metal items in the lower basement include: ceiling/crane access plate, 1 manhole, 1 grab bar above manhole, and 1 fall protection anchor. The staircase from the upper level is excluded. The metal items in the gallery include: all ceiling anchors, 4 rectangular floor grates and frames, 2 round drain grates, 4 staircase pipe railings, 1 manhole cover and frame, 1 sump pump cover, 1 sump pump valve, and 31 Wooster cast iron safety treads. All float well pipes and valves, light switches and cover plates, light fixtures, and electrical components are excluded.

QUESTION 5: There was not a specified approved concrete coatings product and only specs for a product, to allow for the most accurate pricing, please approve the attached product for concrete coatings. SW Macropoxy 5000

RESPONSE 5: The intent is for a non-film forming breathable silane-siloxane base concrete penetrating sealer/hardener. The product is a one-part aqueous solution that will be sprayed in multiple coats (2-min). The Government will not approve products during the solicitation phase.

W912WJ25Q0038

QUESTION 6: Is the Government considering this a Confined Space?

RESPONSE 6: No, the Government is not considering this a confined space.

QUESTION 7: Do you have As-Builts for the pull bars embedded in the ceiling of the gallery? Can

Contractors use them?

RESPONSE 7: The pull bar locations are detailed on record drawing included in the spec TH-1-1304.

Please refer to the pull bar details 49 in the attachment TH-1-1327. Contractors that intend to use the pull bars will be required to conduct strength testing for the bars and submission of the results to the Government prior to use.

QUESTION 8: As stated in the specification it is unknown if existing coatings contain other hazardous materials beyond those locations noted for the presence of lead. Please confirm if additional hazards are found to be present, they shall be addressed through equitable adjustment.

RESPONSE 8: If additional hazards are found to be present, the Contactor shall immediately notify the Technical Point of Contact. The Government will then determine the appropriate course of action regarding the continuation of work for identified areas.
