What type of steel should be used for the stanchion structures? A1. Steel utilized in the stanchions should be hot dipped steel. Q2. What should be done about the welded and cut edges upon completion of a structure? A2. All welded and cut edges shall be galvanized upon completion. Q3. What conditions should be left for stanchions that are to be removed but not replaced? A3. If the stanchion is to be removed but not replaced, then simply remove all metal down to the lowest concrete point, and grind smooth to prevent tripping hazards and lacerations. Q4. How much insulation should be removed for each stanchion to be worked upon? A4. Each stanchion will have approximately 3 linear feet of insulation on each side removed to allow for the work to be performed on the stanchion. It is to the contractor's discretion how to cover the exposed piping as to prevent burning during work on the stanchions. Upon completion the insulation will be replaced onto the exposed piping. Q5. How will the concrete pedestals be affixed to the ground? What concrete should be used? A5. The concrete pedestals are to have bolting into the floor to prevent movement. The flooring is to be drilled for four (4) rebar bolts, to be placed in a square setup for the concrete to be poured. Concrete should be high strength concrete (>3,000 psi) Q6. Is this bid to include/create actual technical specs or are they just doing the work? A6. The offers is to only perform the work specified. Q7. Will the government provide a stress analysis of the materials (stanchions)? A7. No, as it is not necessary. Q8. What type of rebar is to be used? A8. Epoxy Coated Steel Rebar should be used, as is more suitable for corrosive and humid conditions. Q9. Where can details about overtime and weekend shutdown procedures be found? A9. Please refer to Section A10 of the Statement of Work. Q10. If there are additional stanchions found to be in disrepair and need to be replaced, how will they be included into the project? A10. The contractor will be provided an opportunity to submit unit pricing for additional stanchions to be replaced. Q11. The Request For Proposal states that the project be completed in 180 days. If following this timeframe multiple stanchions in an area would need to be removed at a time, leaving the pipe unsupported. Is it GSA's intention for the contractor to install temporary stanchions to support the piping while work is accomplished and utilizing multiple work crews (3-4) in both areas of the system at the same time? A11. The revised Statement of Work has changed to the project completion time to 360 days. The successful contractor will need to make the determine if installing temporary stanchions are warranted. Q12. What is the government's proposed shutdown schedule to demo/replace anchor stanchions, since existing anchors will need to be removed leaving line with no anchor point? A12.

Test results will be made available to the contractor upon request for specific areas. This project does not include provisions for ACM testing or abatement/ disposal. Q15. Define "significant concrete work" to include rebar requirements, maximum depth and total square feet to be repaired at each location. A15. This item has been removed from the specification requirements. Q16. Define how many pipe guides and/or pipe rolls are required by pipe size. Table indicated 4", 6", 8", 10", and 12". Table seems to indicate channel size and not size of pipe to be supported. A16. The table has been modified to provide a listing of the type of stanchion (mid or full size) and pipe guide sizes.
