Tombstone Gym Building

1.) Please clarify where the duct penetrations for the Gym units will be. Onsite discussion was had regarding the duct coming through the existing windows. If the West unit is lined up with the last window on the west side of the gym there will not be enough clearance between the new unit and the existing unit. 2.) If the new west unit is going to be lined up with the window and there is not enough clearance between units, how will this be addressed. Will there be an addendum to move the existing unit? 3) Please clarify if the basketball pad to the north of the gym roof will support a crane.

The new west unit (AC-1) is not lined-up with last window. It is lined-up with the window before last. Refer to bid plan sheet M-1. We could not verify if the basketball court slab is "Fire-Truck Rated". For reference, we are providing the structural as-built (attached) of the existing basketball court slab. This information will be included in Amendment #3. Thank you!

1) Does the school district want any enclosure ie. chain link fencing with man gates around the new package units and condensers? 2) Do the dampers in the ridge vent opening close? If they are not able to be closed will they need to be capped off or sealed from above. Is there any consideration of removing the dampers and re-roofing the ridgevent opening?


Good afternoon, thank you for your inquiry. These questions have been received and will be reviewed. Any changes, if applicable, will be addressed in a future amendment. Thank you!


1) M-1R will be revised in Amendment #3 that shows clouded revisions, which includes new chain-link fences. 2) Existing ridge vent shall be capped from above. Refer to an attached M-1R for ridge-vent sealing detail. This information will be shared in Amendment #3. Thank you!

General Contractor's License


Addendum 1 addresses the work being performed under a General Contractor's License. My company has an in-house General Contracting Company, Munsey Contract & Development, that all the necessary work & subcontractors can perform under. They were not at the mandatory walk thru as this addendum had not been issued. Will we still be able to submit under their license. I do work for both companies and if so needed can represent the General Contracting company and Berg's Heating & Air.


Good afternoon, thank you for your interest in this project. This inquiry has been received and is currently being reviewed. Any changes, if applicable, will be addressed in a future amendment. Thank you!
