On January 7, 1982 I made an inspection of the fire damaged area of this building
to determine the extent of structural damage caused by the fire.
1. The fire was concentrated in the ceiling/roof framing above the tOilet/
furnace room and stock area resulting in structural damage to the ceiling
joists, roof rafters and roof deck in the immediate fire area.
2. One bow string truss was subject to fire exposure to the 'extent where its
continued structural capacity is in question. The char on the various chords
and web members is from a depth of less than 1/16-inch to less than 1/4-inch.
3. Two adjacent bow string trusses were subject to some fire exposure resulting
in very slit;ht char on portions of some members. The only repair to these
t.TO trusses would be the retightening of all bolted connections in the fire
exposed area.
4. The fire damaged ceiling jOists/roof rafters and roof deck which show
extensive char should be removed and replaced. This area is concentrated,
mainly in the two spa)ls between the lJow string trusses noted in ,t.< & 3.'
5. The one bow string truss which sustained the fire damage indicated in #2
should be scraped down to the base wood on charred members and exposed for
inspection by removal of all adjacent construction including the ceiling
joist support ledgers on the bottom chord. After this is done, I should
be notified to make an additional inspection at which time I will determine
the appropriate repair method to restore the truss to original load carrying ,
capacity. I intend that this repair method will involve the following procedures:
a) Retightening of all bolted connections.
b) Installation of additional bolts where necessary.

c) ,Scabbing on of additional wood or steel members on chords or web
members to replace thc charred area with proper attachment and '
connections.
d) Installation of proper truss bracing.
At the time of the subsequent inspection, I will make specific recommendations for
the truss rel'air and ini tiate proper reports, calculation:> and details to perform
the repair for submi;sion to you, the Springfield Building Department and other
concerned parties.
I hope this report is satisfactory for your purposes at this time. Please contact
me if you ha.ve further questions. .
Thank you for this opportunity to be of service.
Very truly yours,
