The access hatch at sandy lake on the roof that got replaced is larger that the opening in the roof The opening In the roof
c roughly 36 x 36 the curb on the roof s rougnly 50 x 50 In your response to RFI 5 you stated that you want the hatch
mounted on a curb, but vv th no cost to the csty so our plan is to reuse the existing curb If this is what we and up doing
we will need a 50 x 54 access hatch. Also to completcate matters there are concrete structural beame in the roof that
would limit the size of this hatch. Please advice.

Install the hatch on the existing curb We understand that this will require a 50 "x50" access
hatch, which per your email dated April 5 2005 (see attached) results in no additional cost to the
City
If you have any further questions, please feel free to contact Erika Cooper at 972 - 735 -3056

Subject. RE access hatch
To use a 50 "x50" there is no additional cost to the city Yes the structural beams do affect the hatch size The existing opening
goes from beam to beam north to south and there is another beam on the Westside of the opening. There is no beam on the
eastside of the opening you have roughly 6" and then there is the exterior wall The opening to the roof would make the hatch
smaller, but installing it on the existing curb would make the hatch bigger The existing curb is set back from the opening. I don't
know if this clear it up or just confuses the situation more, please let me know

Subject: RE: access hatch
Todd,
I received your RFI #007 regarding the access hatch and I'm still not exactly clear on what you are asking If we elect to
reuse the existing curb, which will require an approximate 50 "40" gate, is there any additional cost to the City? Also, do
the structural beams to the roof impact the hatch size regardless of whether or not the hatch is installed with a curb?
Please clarify so I can respond to your RFI
Thanks,
Erika
