submitted on the first CO and contractor will be reimbursed

3. Stair Rail and Guardrail at top of walk should match (one is presently shown as

fabricated steel and one is shown as Ameristar Fence) – also please note the height of

the guard at top of walk.

a. Response: Ignore the Ameristar fence. See structural drawings for railing and

detail. Spindles to be no more than 4” on center.

4. Please specify the finish at the new earth swale next to the building – IE sod, seed and

straw, mulch or landscape rock – if sod, who will be responsible to water and establish

growth?

a. Response: TPO roof. Warranty is obsolete being the roof has not had work done on it

in 25 years

6. We do need to tie into the Fire Alarm System/Panel. Please advise where the Panel is

located and what manufacturer/system is in place so that we can obtain quotes for the

new devices and we know how far to extend wiring.

a. Response: Duct detector for the AHU can be tied into the existing fire alarm loop

located within the adjacent gymnasium. Current fire alarm vendor is Tech

Electronics.

7. Please let us know if there is a preferred roofing contractor that holds the warranty on

the existing roof.

a. Response: The gym roof is over 25 years old so the warranty is obsolete. District

does not have a preferred vendor but would request to approve selected vendor

8. Please confirm the finish for the structural steel W12x45’s and the W8x35’s on the

interior of the project. Are these to be prime painted?

a. Response: Leave as is, no prime and paint needed.

wanting (3) different types of waterproofing?

10. On drawing A310 detail A6 where is this associated on the west or south elevation?

a. Response: South wall (WHICH IS ACTUALLY THE WEST WALL)-that is the enlarged

detail from the south/ (WEST) wall section -titles of wall sections have been

corrected for clarity to match floor plan

11. Is there any existing waterproofing on the walls that we are waterproofing?

a. Response: We do not know if there is any existing waterproofing on the exterior.

It would be favorable to think there is a “tar like” membrane applied from the

original construction of the building,

12. There is a spec calling for the bentonite composite sheet waterproofing, drain board and

protection board. What kind of protection board do they want?

a. Response: Tempered hardboard

process.

know the thickness of the infill?

a. Response: The vents along the gym walls to be filled with concrete. The

northwest corner of the building has damaged brick just above the foundation

wall that needs to be replaced
