a. Question 1: What areas/spaces are considered to be confined space?

b. Response: VASNHCS has a list of areas that are considered permitted and nonpermitted confined spaces. In this project a crawlspace will be considered a confined space. A list of the specific areas at the medical center that are confined spaces and an SOP will be provided to the contractor after contract is awarded.

c. Question 2: Are we to expect any lead or asbestos material in or around the pipes to be removed? And, if so, what are our procedures to address these materials?

d. Response: Asbestos abatement is not included in this construction project.

Previous sampling has not found pipe insulation that contains asbestos in the areas covered in this contract or the asbestos has already been abated. Any materials that are found to have asbestos will be abated per applicable codes and requirements.

e. Question 3: Where exactly will we be cutting off the ‘dead leg’?

f. Response: Must be cut within 1-1/2 diameters of the dead leg pipe. Example; If the dead leg pipe is a 1” diameter pipe, the dead leg must be terminated within 1.5”.

g. Question 4: How many dead legs go back to isolation valves that do not require a shutdown of the water system? Please provide location, size, and quantity.

h. Response: Most, if not all require a shutdown.

i. Question 5: Are there special requirements to de-water the dead legs? Can the water be routed into the sewer system? Please advise and/or provide specification/procedure.

j. Response: Water can be routed to waste water system.

k. Question 6: Is there any requirement for disinfection? If so, to what extent?

l. Response: Yes. Per AWWA C651 and International Plumbing Code.

m. Question 7: According to the dead leg inventory, it appears #185 on the 2nd floor resides behind a restroom/toilet. Can the VA provide information on where that pipe runs with respect to this restroom? Perhaps a picture or plan of the restroom where the pipe is running would be helpful.
