A14. Subgrade is to meet requirements in Specification Section 31 20 00.

Q15. Demo note on this page states: “Demolish all building components to minimum of 4’-0” . . . Identified components are for reference only and contractors are responsible for a pre-demolition survey of existing conditions in conjunction with drawings and specs. In the event existing conditions vary and there are additional identified components. . . Will this be handled as a modification to the contract since there is no way to state existing conditions are for reference only on a design bid build project?

A15. Contractor is responsible for demolishing components to a minimum of 4’-0” below grade. See Drawing Revisions.

Q16. Are we to assume lead paint on all building 45 surfaces? There is a specification but no quantities are listed. Please clarify lead paint quantity or assumptions to make.

A16. In specification section 02 83 33.13 the following quantities of lead-based paint and lead dust are listed as follows:

Universal Wastes/Hazardous Materials

Q17. There are approximately (12) 55-gallon drums located inside the building. Some of the barrels still have liquid inside. Will the VA be removing the barrels prior to demo? If not, will the VA confirm contents of the barrels? If not, contractor will have to characterize contents professionally, which can get very costly. Please advise.

A17. VA will remove these barrels prior to site turn-over

Q18. The Hazardous Materials table includes 10,622 ft.² of lead paint and dust in the boiler and engine houses. Typically, all loose and flaking and previously falling lead paint is removed prior to demolition, however, the complete removal of lead paint is not required in the State of Wisconsin assuming the associated substrate is not going to be recycled and is placed in a construction and demolition approved Landfill. As long as State of Wisconsin guidelines are followed, will complete removal of the lead paint be required unless located on bricks that are being salvaged?

A18. That assumption is correct. Complete removal of intact lead paint is not the intent. The following section of Spec Section 02 83 33.13 in paragraph 3.3:

Q19. Reference spec section 01 35 26 1.12 Tuberculosis Screening: Is tuberculosis screening required for this project? If so, is it acceptable to test only those that answer ‘yes’ to any question on the State of Wisconsin pre-screen questionnaire?

Q20. Is the commissioning agent and all associated costs being supplied by the VA?

A20. No third-party commission agent will be employed. Contractor will “Conduct final tests required in various sections of specifications in presence of an authorized representative of the Contracting Officer” per Spec section 01 00 00.

Q21. If after uncovering existing conditions there is a need for subgrade soil repairs, will the work have to stop until an approved Supplemental Agreement is in place or will there be pre-determined unit rates/costs established so the work can proceed accordingly?

A21. Per the FAR, all work that differs from the drawings, specs and other contract documents must be included in the contract via a contract modification. However, at times depending on the situation contractors at times find it beneficial to perform work at their own risk. As long as the VA agrees with the work to be done, there are rare exceptions when a contractor may make the decision on their own to perform work prior to a modification being issued.

Q22. Per Section 31 20 11 Part 3.6-D contaminated soils need to be segregated from all other excavated soils, stockpiled on 6 mil polyethylene sheets with a polyethylene cover at a designated area. Will the designated area for stockpiling contaminated soils be located with the project boundaries? Is all the soil considered contaminated or is there only isolated areas?

A22. Question is referring to Section 31 20 00 Part 3.6-E. Contaminated soil (containing asbestos) cannot be stockpiled on site. Contaminated soils to be disposed of properly offsite. Soil not containing asbestos is considered historical fill material and can be reused at the project site. All soil not reused must be hauled off-site per Specification 31 20 00 Paragraph 3.6.E. See Specification Revisions.

Q23. Can any of the contaminated soils designated by the Resident Engineer be used as backfill?

Q25. Is there a Soil Profile showing the levels of contaminates for this project and will it be provided? If not, where should we figure the contaminated soils need to and will the VA be providing that paperwork showing compliance with all State and Local requirements?

A25. The VA has a soil profile for historical fill materials from our entire campus, which is primarily low levels of PAH. As agreed with the DNR, the VA sends any unusable soil to licensed landfill as it is assumed the same historical fill is present throughout the campus. It is acceptable to re-use the historical fill material on the site – the VA only uses their profile in the case that disposal of the soil is required. Milwaukee VA GEMS department has documentation to show the DNR guidance given to the VA on this process from 2017. The VA will not be providing soil profile or compliance documentation pre-bid, however, awarded contractor shall work with the COR to establish a disposal profile for the project. See 31 20 00 Specification Revisions.

Q26. Can all work be done during normal daytime work shifts?

A26. See response to Question 2

Q27. Please clarify the scope of work associated with duct testing as there is minimal supply air ductwork. Please be specific what the VA needs tested.

Q35. See sheet GI 001 General Note 2. What City, County & State permits are required for work on Federal Property?

A35. All state and municipal environmental regulations apply to Federal grounds, including permit requirements. The contractor is required to follow all applicable DNR regulatory requirements during the course of this project. However, it was determined that a stormwater permit will not be required as there will be less than 0.5 acres of additional impervious surface.

Q36. See sheet GI 001 General Note 3. Has the NOI been submitted to the Wisconsin Department of Natural Resources? Normally these are done prior to the project as a denial of permit stops the project.

A36. The Awarded Contractor shall submit a NOI per sheet GI001 General note 3.

Q37. See sheet GI 001 Grading Note 5. Where may soil that is to be re-used on site be stockpiled?

A39. Yes, contractor is liable for repairing. Contractor is to protect existing infrastructure. Contractor is responsible for repairing the damages to site entities, per sheet GI001, Demolition note 8.

Q40. See sheet AD101 and AD 301 & AD 302 detail 1. Pits are shown in these details that were not visible during the walk through. Do they need to be excavated as shown? If so what material is in them and if it is contaminated is it an unforeseen condition?

A40. The entire structure including pits are to be removed/excavated as shown. The first four inches of soil need to be removed and disposed of as ACM with the costs included in the bid. Test remaining soil for ACM, if ACM is not present, follow answer to question 8. If ACM is present, repeat steps above. Based on previous abatement work, possible soil contamination is considered to be only surface contamination.

Q41. See sheet DC 101 and the tree protection around an 18” tree. Also see sheet CS 102 that shows asphalt paving and grade changes in the same location. Consider removing the trees or revising the grading plan so they can be preserved.

A41. Question is referring to sheet CD101. Tree protection area is to be maximized to protect tree roots as best as possible.
