Specifications \NY_, \q- Lc c \ -, OFFICE COPY L �� „ t A. 30 31 1 Ford Residence Vehicle Damage Repairs 12350 SW Tiedman Ave Tigard, Oregon 97223 January 29, 2019 For: Tim Young Harbro The JAS Engineering design team has received the request from you to provide structural s .a,. a .clysis,,gpgineering design„ccpsjruction drawings and structural calculations for the project referenced above. We visited the property and assessed the requirements with you. We can prepare plans and calculations for submittal to the City of Tigard, for permitting. OBJECTIVES The JAS team understands that you need engineering services to repair the vehicle damage to your residence located at the address noted above. The existing roof is framed with manrufaetured trusses ate f;ac spanning front to back over the house. The upaperfloorfrgming .. also spans front to back anis supported on a center bearing wall. The vehicle damage is to the a foundation wall at the front of the house, including connections to the upper floor framing and the shear walls at each side of the house and roof framing above. The vehicle impact has broken off the front foundation wall and pushed the upper portion 24” into the house. The right wall has cracking in the sheetrock on the inside near the back of the house and a concrete foundation wall crack in the back right corner. Due to the damage at these locations, the front foundation wall will need to be rebuilt and the side walls strengthened and reconnected to the foundation to support the front wall, floor framing and roof framing and for the shear wall uplift forces due to wind and seismic. The side wall foundations will need to be checked and the repaired/strengthened walls attached to it with epoxy anchors. The front wall and floor framing must be connected to the rebuilt front foundation wall with the front shear walls properly anchored. We recommend the finishes be removed in the front room in the basement, on both sides of the center wall and at the soffit so the damage can be better assessed. The back room in the basement should have the right wall finishes removed along with the closet back wall.

SUITE 100 OREGON CITY, OR 97045 • 503-657-9800 On the upper level, on the front wall at the main entry door there is cracking and the door had to be adjusted to be able to remain in use. Bedroom 1 adjacent to the entry stair has damage in the front wall and near the hallway at the bedroom door. The finishes at the front wall in the main entry and adjacent Bedroom 1 should be removed. In addition, portions of the hallway wall of bedroom 2 and the closet wall through the bedroom door must be opened up. Other access areas may be required once we have had a chance to observe the damage in these locations. This will allow us to assess the damage and develop repairs to rebuild/modify these walls. The JAS team will address the structural damage of the residence due to the vehicle damage and will be preparing plans, engineering and calculations for a complete permitting packet. We have also provided estimated fees to provide the permitting service at the City if you would like us to do this (see the "compensation" section of the contract). We understand you would like us to provide structural calculations and drawings for the design of the repaired walls, floor framing and replacement foundation. We will design the replacement window headers to support the code required roof loads. We understand the project construction is to be built based on the drawings prepared by us. The scope of the project is to provide plans showing the location and extent of the repaired walls a, fr ming alpa0)the rebuilt foundation. We will also proxisjuhsar wal showing-Wear ear nailing and new hold down locations to resist the code required wind and seismic forces for the repaired walls of the house front, right side and interior of the building. JAS Engineering will provide the design to meet the code required roof snow, live load and dead load forces. Structural details will be provided to show the construction requirements for the roof truss to wall connections, wall to foundation and shear wall to foundation connections. We will show non-structural elements such as replacement insulation requirements and roof ventilation locations.
