INFORMATIONAL COMMENTS: 1. Due to the date of receipt of the permit application, this review is based on the 1993 Edition of the State of Oregon Structural Specialty Code and all citations are from this code unless otherwise noted. 2. For mechanical systems this review is based on the 1993 Edition of the State of Oregon Mechanical Specialty Code and hereafter called the "Mechanical Code." 3. Oregon Fire Code is the 1991 Uniform Fire Code with Oregon amendments and hereafter called the "Fire Code." 4. REVISED: The Tire storage room and accessory functions have been reviewed under the provisions of Article 81 of the 1996 Oregon Uniform Fire Code. 5. Group B, Division 2 and Group B, Division 1 Occupancy. Type III -N Construction (sprinkled). Base area: 12,544 square feet (footprint).

A 2 -hour "occupancy separation wall" is provided, running north -south through the building. This wall is not an "area separation wall" required or recognized by the code. Area separation walls are used to divide the building into separate buildings when they are over -area. This building is not over area. The base area of Group B, Division 1 and 2 Occupancies is 12,000 square feet. The code provides for area increases for separations on three sides (12,000 *(55- 20) *2.5= 21,900). Additional increases are allowed by code, but are not explored for this project. Additional issues created by calling this wall an "area separation wall" are: • Area Separation walls for Type III Construction are required to be of 4 -hour fire- resistive construction. Only a 2 -hour fire resistive wall is shown on Sheet A5. Section 505 (f) 2. • Penetrations of the 4 -hour walls are required to have a 3 -hour fire - protection rating. Only 1 '/ -hour fire - protection ratings are given on Sheet A5. Section 505 (f) 2. • Openings in an area separation wall are limited to 25 percent of the length of the wall. Openings in the wall shown represent 34 percent of the wall length. Section 505 (f) 2. • Duct penetrations through 4 -hour area separation walls require three hour fire dampers. No dampers are specified on sheet M1. Section 505 (02 and Section 4306 (f). A one -hour occupancy separation is required at this location between showroom (101) and the alignment/service bay (102). REVISION: The 1996 Oregon Uniform Fire Code in Article 81, Section 8102.2 provides for a 2 -hour "Separation of High -piled Storage area- separation Wall." GENERAL COMMENTS: 1. Original LP Comment: Site storm sewer catch basins shall comply with the design provisions in the State Plumbing Code, Chapter 14. Cleanouts shall be provided at the base of all building raindrains. Architect's Response: Cleanouts will be provided at the base of all building raindrains. Status: RESOLVED. 2. Original LP Comment: Turbine ventilators shown on Sheet S2, near the ridge, do not appear on the elevations or cross - sections. Section 302 (d). Needed for clarity. Architect's Response The turbine ventilators have been shown on the elevations and cross - sections. ,� LINHART PETERSEN POWERS ASSOCIATES 1� v 3855 -3 Wolverine Street NE • Salem, OR 97305 (503) 371 -2212 • FAX: (503) 371 -3853 Less Schwab Tire Center Tire Store 15348 SW Pacific Hwy City of Tigard Tigard Oregon 97223 Response to FirstReview August 13, 1996 Page 4 Status: RESOLVED. FIRE AND LIFE SAFETY: 1. REVISED Original LP Comment: Revise designation of 2 -hour wall as an "area separation wall" and show it as a "two -hour high -piled storage area- separation wall" as allowed in Section 8102.2 of the 1996 Oregon Uniform Fire Code. Architect's Response: The 2 -hour wall has been designated as a two -hour high -piled storage area- separation wall." Status: RESOLVED. 2. REVISED Original LP Comment: The tire storage room (104) satisfies the definition in the Fire Code for "high piled storage." The fire sprinkler system for this area shall be designed for "High- hazard Commodities" (formerly Class V Commodities) and comply with Table 81 -A for "500 -2,500 sq. ft. Nonpublic Accessible (Option 1)." Section 209 definitions, Section 8102 and Table 81 -A of the 1996 Fire Code. Architect's Response: The sprinkler system for Room #104 will be designed for high- hazard commodities" and comply with Table 81 -A for "500 -2500 sq. ft. Nonpublic Accessible (Option 1)." Status: RESOLVED, 3. REVISED Original LP Comment: Downspouts appear to encroach into the vertical clearance of 13 feet 6 inches along the fire apparatus access road on the north side of the building required by Section 902.2.2.1 of the 1996 Oregon Uniform Fire Code. Note, an exception allows the fire chief to vary the clearance and require approved signs reporting impaired clearances. Architect's Response: The authority having jurisdiction for the site design aspects of the fire code regulations in the City of Tigard is the Tualatin Valley Fire & Rescue and Beaverton Fire Department, Gene Burchill, Deputy Fire Marshal and Plans Examiner. In an earlier review, he has concluded that the private road to the north of the building will not be required for fire department access, and is therefore not considered a fire lane. Therefore, the comment that the downspouts are encroaching into the vertical clearance for the fire apparatus access road does not apply. Status: RESOLVED. 4. REVISED Original LP Comment: The fire chief may require the fire apparatus access road to be marked with approved notices identifying the access road and prohibiting its obstruction. Section 901.4.5 of the 1996 Oregon Uniform Fire Code. Architect's Response: See item #3 above. Status: RESOLVED.

For mechanical systems this review is based on the 1993 Edition of the State of Oregon Mechanical Specialty Code and hereafter called the "Mechanical Code." 3. Oregon Fire Code is the 1991 Uniform Fire Code with Oregon amendments and hereafter called the "Fire Code." 4. Group B, Division 2 and Group B, Division 1 Occupancy. Type III -N Construction (sprinkled). Base area: 12,544 square feet (footprint). B -2: 7,648 square feet B -1: 4,896 square feet Stories 2. Occupancy load first floor B -2: 77 B -1: 49 Parking 56 spaces, one van and two non -van required and provided. 5. A 2 -hour "occupancy separation wall" is provided, running north -south through the building. This wall is not an "area separation wall" required or recognized by the code. Area separation walls are used to divide the building into separate buildings when they are over -area. This building is not over area. The base area of Group B, Division 1 and 2 occupancies is 12,000 square feet. The code provides for area increases for separations on three sides (12,000 *(55- 20) *2.5= 21,900). Additional increases are allowed by code, but are not explored for this project. Additional issues created by calling this wall an "area separation wall" are: • Area Separation walls for Type III Construction are required to be of 4 -hour fire- resistive construction. Only a 2 -hour fire resistive wall is shown on Sheet A5. Section 505 (f) 2. • Penetrations of the 4 -hour walls are required to have a 3 -hour fire- protection -- rating. Only 1 1 / 2 -hour fire- protection rating are given on Sheet A5. Section 505 (0 2. • Openings in an area separation wall are limited to 25 percent of the length of the wall. Openings in the wall shown represent 34 percent of the wall length. Section 505 (f) 2. • Duct penetrations through 4 -hour area separation walls require three hour fire dampers. No dampers are specified on sheet M1. Section 505 (02 and Section 4306 (f). A one -hour occupancy sepration is required at this location between showoom (101) and the alignmentservice bay (102).

Site storm sewer catch basins shall comply with the design provisions in the State Plumbing Code, Chapter 14. Cleanouts shall be provided at the base of all building raindrains. 2. Turbine ventilators shown on Sheet S2, near the ridge, do not appear on the elevations or cross - sections. Section 302 (d). Needed for clarity. FIRE AND LIFE SAFETY: 1. Delete designation of 2 -hour wall as an "area separation wall" or make it comply with Sections 505 (02 and 4306 (0. A one -hour occupancy sepration is required at this location between showoom (101) and the alignmentservice bay (102). 2. The tire storage room (104) satisfies the definition in the Fire Code for "high piled storage." The fire sprinkler system for this area shall be designed for Class V Commodities and comply with Table 81.105 -A for 500 -2,501 sq ft. Section 9.110 definitions, Section 81.102 and Table 81.105 -A of the Fire Code.. 3. Downspouts appear to encroach into the vertical clearance of 13 feet 6 inches along the fire apparatus access road on the north side of the building required by Article 10.204 (a) of the Fire Code. Note, an exception allows the fire chief to vary the clearance and require approved signs reporting impaired clearances. 4. The fire chief may require the fire apparatus access road to be marked with approved notices identifying the access road and prohibiting its obstruction. Section 10.206 of the Fire Code. 5. A smoke detection system is required where a high piled storage room is in the building [tire storage room (104)]. As provided in Footnote 2 of Table 81.105 -A of the Fire Code the smoke detection system shall be supervised and installed throughout the building. 6. The tire storage room (104) aisle widths are required to be 8 feet. Article 81.108 and Table 81.105 -A, Footnote 12 of the Fire Code. 7. In the tire storage room (104) aisles are required to extend from the floor to the ceiling unless approved by the fire chief per Article 81.108, Subsection 1. Also see Subsection 3 of Section 81.108 of the Fire Code related to rack supports interfering with the hose stream trajectory. The mezzanine impairs the hose stream trajectory but improves access. 8. In the tire storage room (104) a small 1 - / inch hose connection is required as provide in Section 81.110 of the Fire Code. 9. The handrails and guardrails for the alignment pit on Sheet S3.4 are deemed to satisfy the "not accessible to the public" of Exception 1 after the third paragraph of Section 1712 (a) that allows rails spacing to be up to 12 inches.

In the tire warehouse (104) stairways, handrails and guardrails for the mezzanine access are not detailed. Guardrails are required to comply with Section 1712 (a). Handrails and rise and run for stairways are regulated by Section 3306 (i). Handrail and guardrail spacing would qualify for "not accessible to the public" by Exception 1 after the third paragraph of Section 1712 (a) that allows rails spacing to be up to 12 inches.
