BUILDING SURVEY REPORT
USE AND APPLICATION INSTRUCTIONS
A. GENERAL:
The purpose of this Survey Report is to provide information on a building or structure that will give a
complete description of the construction and occupancy use. The survey will then serve to provide
building documentation to evaluate the construction and occupancy requirements during maintenance
inspections and for firefighters to develop pre -fire plans which aid them in fire fighting and rescue.
The requested information shall be based on the provisions contained in laws and regulations adopted by
the state, county, city and fire district. It is essential that this survey be thorough and complete. If changes
occur, after the survey, documented changes shall be forwarded to the fire district through the building
department upon issuance of the Certificate of Occupancy.
B. WHEN REQUIRED:
When a building permit is required by the Oregon Structural Specialty Code or the Oregon Residential
Specialty Code, except the following:
1. Minor remodels or tenant improvements
2. Group R3 Occupancies
3. Agricultural buildings as defined in ORS Section 455.315
4. Group B, F, M, R, S and U occupancies that are less than 4,000 square feet ground floor area or
less than 20 feet from the lowest finished floor to the highest finished ceiling.
C. BUILDING SURVEY REPORT - GENERAL INSTRUCTIONS:
The survey report lists items, comments, and alternate materials and methods to be reported. Each item
must be answered as per the instructions. Answers such as "checkmarks ", "O.K." and "N.A." are not
appropriate. Each item requires a meaningful answer such as, "None" or "None Required ", if that is the
condition.
Alternate Materials, Methods, or Appeals
When alternate materials or methods or appeals are approved by the building code official, the letters
"AMM" or "Apr shall be placed in the column titled "COMM" (Comments) corresponding to the item
that was altered or appealed. A short statement shall be entered into the "Alternate Materials or
Methods/Appeals" section and documentation signed by the building code official shall be submitted with
the survey form. If Alternate Materials or Methods are used after the survey is complete and submitted, a
copy of the Alternate Material or Method signed by the building code official shall be forwarded to the
fire district.
Conflicts with Current Code
If working with existing construction and there are current code conflicts with the remodel or when there
are extenuating or unusual circumstances, place the letters "SC" (See Comments) in "COMM" column
and note the circumstance in the "Comments" section.
Attachments to the Survey
When there are attachments, place the letters "SA" (See Attachments), in the "COMM" column. When
there are photographs, place the letters "SP" (See Photographs) in the "COMM" column. The number of
attachments is to be indicated at the end of the report in the space provided.
Abbreviations
At the end of this set of instructions is a list of abbreviations that shall be used to fill out the building
survey form. If the abbreviations do not adequately describe the construction, please spell out the
assembly. Please do not use abbreviations that are not included in the attached sheet.
Preparation and Submittals
All reports and attachments prepared shall be legibly printed or typed. A copy of the form on paper or
over the Internet may be obtained from Tualatin Valley Fire & Rescue at www.tvfr.com.
Separate Survey Forms
A separate survey report shall be completed for each building. Unlike the OSSC the survey form looks
at buildings under one roof structure as one building except where pedestrian walkways connect two
buildings. As a guide, if a building permit is needed, a survey is needed.
D. COMPLETING FORM - HEADINGS
The first part of the report deals with the name, location and management of the facility and should be
thoroughly completed as the fire district permanent record is based on this information. This form
furnishes the necessary information as to whom and where letters of deficiencies should be directed.
FMZ (to be filled out by TVF &R)
This is the number assigned to all facilities and occupancies by Tualatin Valley Fire and Rescue. For new
buildings this will be used to start the building maintenance inspection file. If you see this on a building
survey report after the fire district has received it and filled in the FMZ you will see a number that looks
like 6887B- 048 -003. The first 5 digits indicate a %, square mile in the district (based on a statewide grid);
the next three digits indicate a building within that square mile and the last three digits indicate an
occupant in the building. This numbering system is used for file maintenance.
Code Edition
Indicate the edition year of the code(s) that is used to review and construct the building. If the building is
constructed with the 2003 Edition of the OSSC and the 2003 Edition of the OMSC then note "03OSSC,
03OMSC, etc."
For remodeled buildings please indicate with a "R" in front of the year of the edition of the code that the
remodel is made under, i.e. RO3OSSC.
Name of Facility
A facility is a site with two or more buildings on it. Where facilities have names, the name of the facility
shall be inserted under this heading, i.e. Nike World Campus, Intel, etc. If the facility is not named or
there is only one building, the proper information in this space is "None ".
Name of Building
Complete the building name or if there is no name for the building fill in a generic term that will describe
the use of the building, i.e. Bldg. 4 or Joe Jackson Bldg. or office bldg., etc. If the buildings are renamed
during construction or as the Certificate of Occupancy is issued, please send these changes to the fire
marshal's office.
Address
Insert the actual street address of the facility (building). Do not use a Post Office Box. If the address is
for a facility please include the designation of the building if available, i.e. 12345 SW 124 Bldg. 28 or
12345 SW 124 Joe Jackson Bldg.
Owner
The name of the owner or responsible party is to be provided under this heading. This can be an
individual or a company. If a company and a responsible individual's name is known please include this
information.
Telephone Number
This is the number where the building owner can be reached; including the area code.
Architect, Telephone No. and Address
This information will be used if additional information is needed for the facility and or building. Please
include the phone area code.
Contractors Name and Phone Number (not found on form)
This information is not included on the form because it is not needed to conduct maintenance inspections
but is very helpful to make contact during an emergency while the building is under construction. Please
include the phone area code.
E. BUILDING DESCRIPTION
I. Occupancy:
Type. The principal occupancy classification of the building shall be indicated in this space i.e. M, S 1,
etc. Frequently a single building may house several occupancies of different types. For example, a
building may house a private school consisting of classrooms, etc., in one portion and dormitories in
another; or a public school may house classrooms in one portion and have an auditorium in another
section. When this occurs, it is necessary to explain by a general "SC" in the comments section, and so
noted on an attached floor plan.
Use. Give the general use with a generic term, i.e. foundry, educational, beauty shop, apartments with the
number of units, bus station, etc.
Capacity: The only rooms or buildings that need to be reported are those that are required to be posted
by the OSSC. The capacity shall be determined in the manner set forth by OSSC.
In licensed facilities, indicate the number of licensed ambulatory and/or non - ambulatory occupants and
the age range.
In non - licensed facilities, indicate the maximum occupant load of the building.
In multi -use buildings or rooms indicate by room the capacity for each use, the nature of the use and the
occupant load factor used.
Example: Conference Rm #105 500 (@ 7)
Dining Rm# 105 233 (@ 15)
Conference Rm#206 65 (@ 15)
2. Construction Type and Year Built: In dealing with types of constriction, refer to the classifications
by the OSSC. Construction is divided into five principal types. Be sure to indicate if one hour fire -
resistive (See O.S.S.C. Chapters 5 and 6). The age of the building is indicated by date of construction. If
this form is being filled out for a remodel then place "R" in front of the date.
3. Area (Sq. Ft.): Be sure to include the usable areas that are covered by roof like drive through areas,
apartment balconies, etc.
Total: The area of a building is the total area of the ground floor (footprint) and shall not be misconstrued
as the total area of all floors. The area should be indicated in square feet.
Largest Floor: Fill this in if different than other floors above the ground floor, otherwise use None.
Area of Basement: The total area of the basement (or basements where there is more than one) should be
indicated in square feet. Indicate where basements are sprinkler protected with "AS ". Usable spaces under
main floor shall be noted in the basement space.
4. Stories in Height: Under this heading, the maximum height of the building in stories shall be
indicated. If a portion is a different height, provide an elevation sketch to illustrate the various heights.
Indicate Yes or No if building is classified as a High Rise.
5a. Exterior Wall Construction: Construction material used in exterior walls shall be indicated by
identifying the type of construction materials. Give the required fire resistive rate of the wall(s) by wall
indicating direction (N, S, E, W), i.e. N- WF -lhr. See abbreviations at the end of this instruction book. If
the entire building is fire resistive construction there is no need to indicate the fire resistive construction
of the walls unless a different fire resistive rating is required. As an example the building is one hour
construction throughout, but the north wall, due to location to property line, is required to be 2 hour fire
resistive construction.
5b. Opening Protection: If openings do not require protection, indicate by stating "None ". If openings
are required to be protected, indicate by stating "Yes ". Where openings are required to be protected
indicate the side (N, S, E, W) of the building. If other than a normal 3 /4 hour fire resistive fire - assembly,
then indicate AMM in the "COMM" column and attach the building official's signed documentation at
the end of the survey.
6. Interior Wall Construction: This item covers interior room walls and ceilings. The sequence of
description of walls is from either side, i.e. GLP on SF (Gypsum Lath & Plaster on Steel Frame). Ceilings
shall be described from the room side working up, i.e. GB on WT (Gypsum Board on Wood Truss).
7. Floor Construction: Floors shall be described starting from the top surface and working down. Use
the same method as describing a wall. It is important to include floor covering, floor, sub -floor, framing
and ceiling. When you have a multi -story building, the floor and roof are quite often a part of a required
floor - ceiling or roof - ceiling assembly. If a fire resistive rating is required other than the requirements of
the building construction, indicate the fire resistiveness required.

Excel Automated Fire Flow Worksheet Instructions
1. Scope
The following lists the procedure for determining required fire -flows using the Excel spreadsheet located on the TVF&R
website. The calculations are derived from the 2003 IFC Appendix B as amended by TVF &R Fire Prevention Ordinance
04 -01.
2. Definitions
A. Fire Area is the floor area used to determine the required fire flow (sq ft).
B. Occupancy Hazard is the degree of fire hazard for a particular business or building use. This is related to the amount
of available fuel and the intensity of the fire.
C. Fire Flow is the flow rate of water supply available for fire fighting measured at 20 psi residual pressure.
1. Applicable fire flow is maximum amount of water flow the fire department resources can produce (3,000
GPM). It also describes the acceptable levels of loss the fire district is willing to occur in a single fire.
2. Required fire flow is calculated water flow required to fight a fire in a specific building and occupancy hazard
(GPM).
3. Modifications to Required Fire Flow
The Fire Marshal may reduce fire flow requirements for isolated buildings or a group of buildings in rural areas or
small communities where the development of full fire -flow requirements is impractical The fire flow requirements
may be increased where conditions indicate an unusual susceptibility to group fires or conflagrations. A modification
shall not be more than twice that required for the building under consideration.
4. Fire Area
A. General:
The fire area shall be the total floor area of all floor levels within the exterior walls and under the horizontal
projections of the roof of a building, except as modified in this section.
B. Area Separation:
Portions of buildings separated by fire walls without openings constructed in accordance with the Oregon Structural
Specialty Code may be considered as separate fire areas for determining the required fire flow.
C. Type IA and Type IB Construction:
The fire area of buildings constructed of Type IA and Type IB construction shall be the area of the three largest
successive floors.
D. Open Parking Garages:
Fire -flow calculation area for open parking garages shall be determined by the area of the largest floor.
5. General Building Information
a. Complete the building information.
b. Choose a construction type from the drop down list.
c. Enter Total Bldg and Fire Area (see definitions above for details)
d. At this point the spreadsheet will automatically calculate the Bldg Fire Flow.
6. Occupancy Hazard (Section A)
a. If building is a single occupancy hazard, enter total fire area in square footage under a single hazard class (see
occupancy hazard factors below).
b. If building contains multiply occupancy hazards, enter the fire area in square footage for each occupancy hazard
class (see occupancy hazard factors above).
c. The Building Fire Flow will automatically to be calculated and entered on Line A3.
Occupancy Hazard Multiple Factor.
Light Hazard Occupancies 1.00
Ordinary Hazard (Group 1) 1.20
Ordinary Hazard (Group 2) 1.30
Extra Hazard (Group 1) 1.40
Extra Hazard (Group 2) 1.50
Example of hazo drlassification - The following examples represent the norm for those occupancy types. Unusual or
abnormal fuel loading, combustible characteristics and potential changes in these characteristics must be considered
when classifying the occupancy.
A. Light Hazard.
Occupancies or portions of occupancies where the quantity and /or combustibility of contents is low and fires
with relatively low rates of heat release are expected. This would include occupancies having conditions similar

8. Fire Hydrants Required (Section B)
a. The number of required fire hydrants is automatically calculated and entered here. The number of fire hydrants is
calculated based on the fire flow prior to applying the reductions allowed in Section D. The actual number of
required fire hydrants may be more than indicated in this section due to distance requirements.
9. Reduction of Fire Flow (Section C)
A. Use this section to determine the amount of reduction in fire flow to be used for Section D
a. Residential Occupancies — The minimum required fire flow shall be permitted to be reduced by 25 percent for
Group R occupancies without fire sprinklers only. (Line Cl)
b. Fire Protection Reductions — The total required fire flow for a building may be reduced by one of the following
options. The resulting fire flow must be no less than 1500 GPM @ 20 psi residuaL
1. Flow may be reduced by 75 percent where a complete approved automatic fire extinguishing system is

Dear Cheryl,
E•R / NG
Thank you for the opportunity to review the proposed site plan surrounding the above named development
project. Tualatin Valley Fire & Rescue endorses this proposal predicated on the following criteria and conditions
of approval:
1) DEAD END ROADS: Dead end fire apparatus access roads in excess of 150 feet in length shall be
provided with an approved turnaround. (IFC 503.2.5)
2) FIRE APPARATUS ACCESS ROAD WIDTH AND VERTICAL CLEARANCE: Fire apparatus access roads
shall have an unobstructed width of not less than 20 feet (12 feet for up to two dwelling units and accessory
buildings), and an unobstructed vertical clearance of not less than 13 feet 6 inches. Where fire apparatus
roadways are less than 26 feet wide, "NO PARKING" signs shall be installed on both sides of the roadway
and in turnarounds as needed. Where fire apparatus roadways are more than 28 feet wide but less than 32
feet wide, "NO PARKING" signs shall be installed on one side of the roadway and in turnarounds as
needed. Where fire apparatus roadways are 32 feet wide or more, parking is not restricted. (IFC 503.2.1)
The fire district does not endorse the design concept wherein 20 feet of unobstructed roadway is
not provided.
3) FIRE APPARATUS ACCESS ROADS WITH FIRE HYDRANTS: Where a fire hydrant is located on a fire
apparatus access road, the minimum road width shall be 26 feet. (IFC D103.1)
4) NO PARKING SIGNS: Where fire apparatus roadways are not of sufficient width to accommodate parked
vehicles and 20 feet of unobstructed driving surface, "No Parking" signs shall be installed on one or both
sides of the roadway and in turnarounds as needed. Roads 26 feet wide or less shall be posted on both
sides as a fire lane. Roads more than 26 feet wide to 32 feet wide shall be posted on one side as a fire
lane. Signs shall read "NO PARKING - FIRE LANE" and shall be installed with a clear space above grade
level of 7 feet. Signs shall be 12 inches wide by 18 inches high and shall have red letters on a white
reflective background. (IFC D103.6)
5) SURFACE AND LOAD CAPACITIES: Fire apparatus access roads shall be of an all- weather surface that
is easily distinguishable from the surrounding area and is capable of supporting not less than 12,500 pounds
point load (wheel load) and 75,000 pounds live load (gross vehicle weight). You may need to provide
documentation from a registered engineer that the design will be capable of supporting such loading. (IFC
D102.1)
6) COMMERCIAL BUILDINGS - REQUIRED FIRE FLOW: The required fire flow for the building shall not
exceed 3,000 gallons per minute (GPM) or the available GPM in the water delivery system at 20 psi,
whichever is less as calculated using IFC, Appendix B. A worksheet for calculating the required fire flow is
available from the Fire Marshal's Office. (IFC B105.2)
7) FIRE HYDRANT NUMBER AND DISTRIBUTION: The minimum number and distribution of fire hydrants
available to a building shall not be less than that listed in Appendix C, Table C 105.1.
Considerations for placing fire hydrants may be as follows:
• Existing hydrants in the area may be used to meet the required number of hydrants as approved.
Hydrants that are up to 600 feet away from the nearest point of a subject building that is protected
with fire sprinklers may contribute to the required number of hydrants.
• Hydrants that are ,arated from the subject building by railro, .racks shall not contribute to the
required number of hydrants unless approved by the fire code official.
• Hydrants that are separated from the subject building by divided highways or freeways shall not
contribute to the required number of hydrants. Heavily traveled collector streets only as approved
by the fire code official.
• Hydrants that are accessible only by a bridge shall be acceptable to contribute to the required
number of hydrants only if approved by the fire code official.
8) FIRE HYDRANT DISTANCE FROM AN ACCESS ROAD: Fire hydrants shall be located not more than 15
feet from an approved fire apparatus access roadway. (IFC C102.1)
9) REFLECTIVE HYDRANT MARKERS: Fire hydrant locations shall be identified by the installation of
reflective markers. The markers shall be blue. They shall be located adjacent and to the side of the
centerline of the access road way that the fire hydrant is located on. In case that there is no center line,
then assume a centerline, and place the reflectors accordingly. (IFC 508.5.4)
10) ACCESS AND FIRE FIGHTING WATER SUPPLY DURING CONSTRUCTION: Approved fire apparatus
access roadways and fire fighting water supplies shall be installed and operational prior to any combustible
construction or storage of combustible materials on the site. (IFC 1410.1 & 1412.1)
We trust this letter will be helpful with the design of this proposal insofar as fire apparatus access and firefighting
water supplies are concerned. If there is anything about this letter you do not understand, disagree with, or wish
to discuss further, please call me.
Sincerely,
John K. Dalby
