Re: Water Dama1!e Insnection at 225 Main Street. Sorim!field. OR - Job # ko6139
As you requested, an inspection was performed at 225 Main Street, Springfield, on December I,
2006, to examine water damage from a portion of the roof collapsing into the building. The total
structure is 50'x96', with south 50'x36' section of the roofat a higher elevation. The collapsed
section of roof was at the lower elevation, near the center of the west exterior wall of the
structure. The building is constructed with concrete masonry unit exterior walls, and various
wood and metal stud interior walls (insulated furring walls at inside fuce of exterior walls). The
flat roof is wood t<uu..J with 2x8's at 1 T' on center, Ix8 shiplap decking, and asphalt roll
roofing. The interior has drop down suspended ceilings. The floors are concrete slab on grade
with various floor coverings.
The following observations were made during the inspection. The damaged flat roof slopes from
the north wall of the structure to the south, where the building steps up in height. The only roof
drain to collect water for this 50'x60' section was located in the southwest comer of the lower
roof. The roof drain is a four-inch diameter pipe that takes water vertically down into the
building before tying into the four-inch diameter pipe from the roof drain for the upper roof.
These two roof drains do not have overflow outlets, and all of the water from the entire roof goes
into the single four-inch diameter metal drainpipe that disappears into the floor. The collapsed
section of roof extends approximately 16' to the east of the west exterior wall, and 36' to the
north from the southwest comer of the lower roof. The 2x8 roof joists, decking, roofing, and
suspended ceiling in the area of collapse is hanging in the air or lying on the floor inside of the
building. There was also a mechanical unit on the roof in this area that is now lying on its side
on the floor. Portions ofthe triple and quadruple 2xl0 beams supporting the roof suffered
damage, as well as a ha1fwall in the room below the collapse. It is hard to determine the amount
of water that must have ponded on the roof to cause the collapse. However water, insulation, and
other debris could be found in virtually every room within the structure. By the time of the
inspection some of the debris and water had been removed, but there was still several inches of
water in some of the rooms, especially the one directly below the collapsed roof.
A thorough investigation and assessment of damage could not be completed with all of the debris
still within the structure. The debris needs to be removed and the remaining sections of roof

temporarily shored where required so a more extensive inspection can be performed to determine
to total scope of repairs required. The existing 4" diameter storm water drainpipe for the roof
should be tested to verifY that it works properly and that the water goes to a reliable outlet. All
repairs to the structure will be in compliance with the State of Oregon 2004 Structural Specialty
Code as adopted by the City of Springfield. A repair plan for obtaining a building permit to
perform the required repairs can be developed upon request.
Damage not noted above that is discovered during the cleaning, exposing, and repair of the
structure should be brought to the attention ofKP Engineering, P.C. Thank you for this
opportunity to be of service. If you have any further questions please do not hesitate to call me at
(541) 393-0782.
Very truly yours,
Kevin M. Peterson, P.E.
