c. Refer to Article 11–Additional Project Completion or Project Close-Out Required.

• A boiler inspection shall be required for new piping supporting the existing steam to water heat exchanger.

d. Refer to Article 12–Special Project Site Security or Access Requirements.

• The Department of Corrections has provided the below written responses to specific Contractor inquiries. Contractor may also refer to attached site access image for location of identified site elements.

1) Storage- Would there be an option for a closed container to be delivered to house tools, materials, etc? I know it was discussed for an enclosed trailer, but I was asked about a Conex, so I wanted to get a written answer.

You could have a Conex box for storage of tools and materials, it would be housed in the lower parking by what is identified as Cellhouse 5 Walls Stand, it’s the parking lot on the right off Hwy 730 and before you get to the entrance station.

2) Concrete cutting/coring- The saw for this needs 480V to run. The Coring company has a truck mounted generator that can supply power to the saws, but I guess my question is, what limitations will be in place for vehicles to enter the job site? Will there be regulations on who can come in at what time? As in, if I am the GC and have a crew working out of my enclosed trailer or what have you, would they have to be packed up and out before the other came in? I’m just trying to make sure I am covering all of the bases and capturing scheduling costs accurately.

If a truck is needed with a concrete saw to perform the work, then KSP will make arrangements for the truck to come in, most likely both crews can work at the same time.

3) Disposal- What is the proposed method for debris removal? Would a dump trailer be sufficient, and how close would we be able to get it? I don’t imagine a roll off would work in this situation.

Either a trailer or dump truck can come on the yard (shower house area) to remove the debris and then will need to be escorted off the yard as soon as the debris is loaded.

You can pull right up beside the building. A small dump truck would better because a truck and trailer mostly likely would involve opening both gates of the sally port to the outside at once, but this can take place if necessary.
