Re:
Integrity of the 2 Hr fire Wall
The Brownstones on Guilford
6 Unit Structure
~3-
In order to restore the designed integrity of the 2-hour firewall between each unit the following
items shall be enacted: I
1. All structural elements shall be isolated from the firewall. Cripples may be installed as,
required beneath each bearing condition. A licensed engineer shall certify all lam
beams that are used to transfer vertical loads.
2. Joist hangers may be used and shall conform to all conditions of the International
Building Code.
3. (2) Layers of 5/8" FC drywall shall wrap around exposed wood studs at intersection of I
exterior walls to comply with the requirement of extending all (2) hr firewalls to the '
exterior sheathing.
4. Drafts stops shall be installed as required.
5. All nails that are currently used to secure drywall shall be considered temporary.
Approved drywall screws shall be installed to the required depth and covered with
approved spackling compound.
6. Approved caulking shall seal all cracks and openings.

Re: Guilford Reserve - Units 4-9 Stair Modifications
SeE Job #06080
Dear David:
As you requested, I visited units 4 through 9 of the town homes being
constructed at the Guilford Reserve development in Carmel, Indiana. The fire
inspector is requiring that stair landings and stringers be re-supported in such
a way that the load bearing members will not penetrate the firewall between the
units.
Your plan for correcting this problem as described to me is as follows:
. Shore the existing framing that penetrates the firewall.
. Cut back the existing headers and landing framing that penetrate the
firewall.
. Install new gypsum board over the penetrations in the firewall.
. Re-support the cut back headers and landing framing with a new load-
bearing wall built beside the firewall. The new load-bearing walls will stack
up from the foundation to the higher stair landings.
It is my opinion that these new load bearing walls will be adequate to support
the stair landings and stringers.
Please let me know if you need any additional information.
Sincerely, ._..~_
