2 Task B added 5” bypass valve to be replaced? Task B See SOW Part 3, Task B

Building 30 south penthouse heat exchangers to be re insulated it is apparent there has been leaks on systems.

Before we insulate lines, leaks to be repaired? By who?

Task A See SOW Part 5

Can we get a linear footage and pipe size to figure insulation?

Any images to view?

Building 11A Crawlspace

Task was removed

(2) valves appear to be leaking near pump. Until it’s uncovered don’t know exactly where leak is coming from.

Who is responsible for investigation and repairs before insulation is applied?

Building 11A task 6&7

See SOW Part 5

PER PART THREE TASK A THROUGH D- CONFIRM PIPING

QUANTITIES. WE ARE CONCERNED WHERE WE START AND

STOP INSULATION AS WE DON'T KNOW THE FULL LENGTH OF

PIPE OR THE EXPECTIONS FOR INSULATION TO STOP. MAYBE

THE FACILITY HAS A ONE LINE SKETCH FOR EACH VALVE

LOCATION AND WHERE THEY WANT THE CONTRACTOR TO

TERMINATE INSULATION.

Is there on-site storage for tools and materials within the mechanical spaces?

See SOW Part 6, Item 5

VA indicated that crawlspace was confined space. What are confined space requirements?

Crawlspace task was removed

Can insulation work be done during normal working hours or nights and weekends?

See SOW Part 6, Item 2

Please provide the linear footage, the diameter of pipes, heat exchanger sizes, and fittings at each location for the accurate proposal, so all the bidders can bid the same scope.

SOW Part 3 See SOW Part 3

There were 4 heat exchangers in the room. We were told that only 2 of the heat exchangers need to reinsulate. Please confirm and provide linear footage, pipe size, heat exchanger size, and fittings to figure insulation.

Building 11A task

There is only 2 functional heat exchangers in this room. The third heat exchanger is abandoned in place and not part of the scope. See SOW Part 3.

Please provide an asbestos survey report for all the locations and scope involved in this project.
