On sheet SHTNO- 10 doors labeled S, it says replace openers with chain auxiliary chain. It requests 1/3hp and 110v. The question is: Those are large heavy doors so it is not recommended to do anything less than 1/2hp, and has it been verified that it is in fact 110V? The power disconnects up near the existing operators are more consistent with 3 phase power which is typically 230/460. I have a hard time believing the existing openers are 110V, but maybe you are running all new power out there and changing it to 110V? Fairly confident someone only checked the one door in room 113 that is not listed for replacement and assumed the rest of them are 110v like that one is.

That is correct, the contract asks for minimum 1/3 hp and 110v.

The voltage has been checked by 138th personnel. With that being said, contractor shall verify voltage as well.

Sheet SHTNO-All doors labeled as S to replace tension wires and springs on all doors. To verify that you want to replace both cables and a pair of torsion springs on each door? Do you have a measurement of the springs that are on those doors? Wire size, length, diameter, and diameter of the shaft?

Correct, replace exisiting cables and torsion springs on each door.

Contractor shall verify measurement of springs on the doors listed.

If another site visit is needed, contact the 138th Contracting office for scheduling.

Sheet SHTNO- In room 112, that existing operator is an explosion resistant opener. It is an entirely different opener than anywhere else in that building. Does room 112 need to be replaced with a new explosion resistant opener or has that room been repurposed since its original conception and can now have a standard opener that we are putting on the other 9 doors listed S?

No, room 112 does not need to be replaced with a new explosion resistant opener. The room has been repurposed and can have a standard opener.

Sheet B329 they have door 1 listed as replace with new matching door: By matching are you requiring the same brand and model as existing or can it be a door with equal or greater specs?

The door must be replaced with equal or greater specs. Door one does not have to match brand and model of existing, matching is referring to the appearance/color.

6/23/2023 12

Sheet B329 doors 2-5-demo safety edges back to source and install new safety eyes/motion sensors. Do you want photo eyes and motion sensors? Motion sensors are where motion is detected and it automatically opens the door.

Safety eyes are when the door is coming down, it will reverse when they are crossed.

With the removal of the existing safety edges, there will be a need for new safety sensors. The contractor shall install a new safety
