140P2021R0018 Questions and Answers – Amendment #0002 03/17/2021

The following is a consolidated list vendor questions submitted prior to the submission deadline. All questions submitted prior to the deadline have been incorporated; however, please note that some of the attached questions are still pending responses, which will be provided in a future amendment.

1. Please confirm if taxes should be carried in proposals?

Response: Please note offerors are to include in their prices all taxes.

2. Please confirm if any state, local, and/or Federal permits will be required on this project?

Response: Permits will be required for lead based paint and asbestos.

3. Please confirm if there are any known hazardous materials?

Response: Construction and contracting documents included a hazardous material survey/report that identified hazardous materials. Please contact the NPS if documents are missing/incomplete.

4. Spec Section 099713 1.4, C Contractors Qualifications, a. Current SSPC QP-1/2: ** Will NACE Certified Inspection be accepted in lieu of this requirement?

Response: Recommend proposal submission with all relevant experience for consideration. NPS would like to know if company has held or working toward obtaining requested certification.

Awaiting additional information on importance of certificate to project vs. past work experience.

5. Please confirm if both cranes can be worked on simultaneously?

Response: The Contractor is responsible for means and method. The work area around both cranes include staging/laydown. Simultaneous work may reduce time but may increase cost. The available workspace is limited and may limit productivity of working on the cranes simultaneously.

Recommend narrative in proposal on approach to work on cranes concurrently.

6. Please confirm the ability to work longer shift days or weekends?

Response: Approval from Contracting Officer is required to work hours outside stated times in the specifications. Location and interaction with the public may influence the availability of hours that can be worked. Work will not be allowed to be performed during special programs at CASSIN YOUNG (Work on Crane 62 would be disruptive).

7. Please confirm the Finish Topcoat is to be a Polysiloxane (PPG PSX 700) and not an Aliphatic Urethane. ** An Epoxy Intermediate (Amercoat 240) is already being used?

Response: Pending response.

8. Please clarify Staging and Rigging Plans to Access the Area/Surfaces. Will full shrink wrapping be required?

Response: Staging will be located near the cranes. Space for staging is limited. Potential movement of cranes towards interior has a limited distance (4-6 ft.). Recommend questionnaire to add more information, is delineation between full vs. partial? Pending response regarding rigging plan and full shrink wrap.

9. Please confirm if doors and windows that will be removed and reinstalled can be taken off site to be painted?

Response: Pending response. Consider a means and method, and removal may be an acceptable option with a written plan for execution and be understanding of roles and responsibility.

10. Would the Parks Service consider awarding the subject project to a contractor that does not have an active SSPC QP1 & 2 certification and intends to perform the painting scope of work in house?

Response: Pending response.

11. In lieu of the certification would the department consider verifiable past performance of comparable projects, specifically historic in nature that involved surface preparation and painting metal structures?

12. Would the Parks Service consider any other certifications or is the certification requirement sole source?

Response: Pending response.

13. There are two CLIN's: #4 OPTION B, Maintenance Contract- CRANE 62 and #6 OPTION D, Maintenance Contract- CRANE 65. Please clarify the scope of work for each of those options.

14. In Section 09 97 13 - STEEL COATING, page 16, Item 3.4.C. Initial Preparation, paragraph 1.b) states:

"Before the cleaning solution dries on the surface, remove contaminants, cleaner/degreaser solution, all loose mill scale, loose rust and other corrosion products, and loose coating by thoroughly pressure washing and preparing surfaces in accordance with SSPC SP WJ-2 using Surface Preparation Water at a stand-off distance and pressure range established in mock-up testing."

Further below Item D.1 states: "Prepare surfaces in accordance with SSPC-SP10." Please note that WJ-2 is not a standard used to remove contaminants, cleaner/degreaser solution, all loose mill scale, loose rust and other corrosion products, and loose coating. WJ-2 just like SP-10 fully removes all coatings at same level of cleanliness. The difference is water vs. abrasive media. If the intent is to create a profile on the steel, then after SSPC SP-1 Cleaning, abrasive blasting to an SSPC SP-10 Near White Blast Cleaning as you state is what it should be required not WJ-2 and then SP-10. Please clarify.

15. Please confirm the Park Service will be moving Crane 65 prior to construction and the entire length of the boom will be accessible from Park Service property. Where will the crane be moved to?

Response: Similar to previous questions. Movement towards the interior is limited. Unsure if the crane would be able to clear entrance/gate for intended intent of proposed work.

16. Is it acceptable for the contractor to remove the booms and lower to the ground for repairs/painting?

Response: The Park recalls that from a previous project that the booms may be lowered, but not easily. Mechanical/Electrical are not operational. Recommend Contractor to provide brief narrative with approach with work by lowering booms and work plan if selected to perform work. We’re currently in the process of trying to get verification from the A-E.

17. Spec section 09 91 13 para 1.10 refers to a 5 year no dollar limit warranty for manufacturer and contractor and a 10 year warranty from the manufacturer for the coating system. Please confirm this is required in addition to the standard 1 year warranty of construction.

Response: Yes, the additional warranties are required.

18. This is a unique project and projects of this nature do not come around very often. Would the Government be willing to extend the 7 year limit for past experience to 10 years?

Response: Yes, the past experience limit has been extended to 10 years.
