IV. Fire District No. 1
A. Requirements/Responses:
1. THE PROPOSED ABOVE GROUND FUEL STORAGE TANKS NEED TO BE k--
PROTECTED BY A FENCE AND WARNING SIGNS. This is done; see attached
Addendum No. 1, Drawing CA-3.
V. Division of Buildings
A. Requirements/Responses:
1. Barrier-Free Requirements:
a. AT DOORS 107A, 109B, 114, 119, 15A AND B, PROVIDE 18" TO THE
SIDE OF THE STRIKE JAMB. Room 107 is served by Doors 107A and
107B. Handicap patients can use Door 107B which has over 18" at the strike
jamb. Room 109 is served by Doors 109A and 109B. Handicap patients can
use Door 109A which has 18" at the strike jamb. Room 114 is strictly a staff
area but should there be handicap staff members, they could access the space by
Door 109A. Door 119 has been moved closer to the east wall, which will
provide the required 18" clearance, by Addendum No. 1. At Door 152A, the
countertop will be shortened to provide the required 18" clearance. This will
be done by clarification as the project has already been bid. Door 152B will be
reversed. It will now swing into Room 153, which will provide the required
18" clearance. This also will be a clarification.
b. DOOR 121 REQUIRES 12" CLEARANCE ON THE NON-SWING SIDE OF
THE STRIKE JAMB. The janitor's floor sink was moved further into the room
by Addendum No. 1. This will allow the required clearance.
c. THE LANDING AT ENTRY TO ROOM 172 MUST MEET SECTION 3304
UBC. This landing was revised by Addendum No. 1.
2. Construction Comments:
a. ABOVE GROUND FUEL STORAGE TANKS MUST BE PROPERLY 4-
VENTED; MUST HAVE SECONDARY CONTAINMENT; AND MUST
HAVE SECURITY AND SIGNAGE.
1) Fuel tank venting shall be extended to above roof lines. (See
Mechanical Addendum No. 1 -Drawings, Sheet M3.3, 1 and 2.)
2) The fuel tanks shall be built to U.L. 142 above ground tank
specifications, which includes explosion venting. (See Mechanical
Addendum No. 2 - Specifications, Section 15176, 1.02.) Note: The
300 gallon tank size called for on this project is not commercially
available with U.L. label. The tanks will be built to U.L. specifications
but will not have label.
3) The fuel tanks specified have secondary containment. (See
Specifications, Section 15176, 2.01, A.2.)

4) A separate tank installation permit shall be obtained from County. (See
Mechanical Addendum No. 1 - Specifications, Section 15176, 1.01, A.)
5) Security and signage shall be provided around tank construction sites.
(See Mechanical Addendum No. 1 - Specifications, Section 15176,
3.01, C.)
b. OBSERVE SPECIAL REQUIREMENTS FOR SUPPLY OF HIGH-
PRESSURE MEDICAL GAS SUPPLY CYLINDER. No new work is being
done in this area.
c. OBTAIN THE SERVICES OF AN INDEPENDENT TESTING AGENCY.
This will be done by the time the response to review comments are resubmitted
to the County.
d. USE APPROVED STRUCTURAL STEEL FABRICATOR. This will be done.
e. ALL WOOD IN TYPE I - F.R. PORTIONS OF PROJECT TO BE FIRE
RETARDANT TREATED. This was clarified in Addendum No. 1.
f. PROVIDE DESIGN SUBMITTALS FOR FIRE-RESISTIVE
REQUIREMENTS FOR THE FOLLOWING: ONE-HOUR CEILING AT
TYPE V - 1-HOUR OUTPATIENT AREA; THREE-HOUR STRUCTURAL
FRAME FOR TYPE I - F.R. AREA; AND TWO-HOUR CEILING/ROOF,
AND EXTERIOR WALLS MEETING SECTION 1803 FOR TYPE I - F.R.
AREA. The ceiling in the Type V - 1-hour area is 5/8" Type "X" gypsum
board attached to underside of wood joists at 16" o.c. with 5/8" thick, 12" x
12" acoustical ceiling panels directly attached to gypsum board. Because this is
an existing facility, we have no research reports or design submittals for this
system. The three-hour structural frame for the Type I - F.R. area follows
U.L. Fire Resistance Directory Design No. X528 for the tube steel columns in
Medical Records and No. X507 for the existing wide flange columns in
Radiology. See attachments. Also, see Addendum No. 1 Clarification
Drawing CA-4. The two-hour ceiling/roof follows U.L. Design No. P711.
For the exterior walls in the Type I-F.R. area, we would ask for the Exception
No. 1, under Sec. 1803 (a) exterior walls, that allows nonbearing walls fronting
on public ways or yards with a width of at least 40 feet to have unprotected
noncombustible construction.
g. PROVIDE MSDS SHEETS FOR CHEMICALS SUBMITTED ON
HAZARDOUS MATERIALS WORKSHEETS. These sheets were submitted
by Tom Fox, from the Valley Hospital, during the pre-construction conference.

entry to Room#166.
2) Area is sprinkled,• see mechanical drawings. X-Ray rooms are
protected by Halon systems, see mechanical drawings.
3) Magnetic door closures, Halon system tie to fire alarm system noted in
Drawing E3.2. Existing audio/visual signals in corridors to remain as
they are.
i. PROVIDE DETAILS OF EXIT SIGNAGE.
Outpatient Area
1) Exit signs are existing, egress lighting added. See Drawing E2.1.
Records and X-Ray Area
1) Exit signs are existing, egress lighting added. See Drawing E3.1.
3. Energy Comments:
a. SUBMIT HEAT CALCULATIONS FOR PROPOSED BUILDING WHICH
MEET MINIMUM REQUIREMENT OF THE WASHINGTON STATE
ENERGY CODE. See attached WSEC requirements and heat loss calculations.
b. PROVIDE LIGHTING LAY-OUT, SWITCHES AND CONTROLS
INCLUDING LIGHT FIXTURE SCHEDULE SHOWING THE
SPECIFICATIONS AND WATTAGE. ALSO PROVIDE LIGHTING
BUDGET CALCULATIONS FOR INTERIOR AND EXTERIOR PORTIONS
OF THE BUILDING, INCLUDING PARKING AREA, PER SECTION 505

b. SUPPORTS FOR THE CONDENSING UNITS SHALL BE NON-
COMBUSTIBLE. Treated 4x4's are being replaced with steel curbs for
support of condensing units. (See Mechanical Addendum No. 1 - Drawings,
Sheet M5.1, 1.)
c. VERIFY BRACKETS AND PRE-CAST UNITS SUPPORTING DUCTS ON
ROOF ARE ADEQUATE TO RESIST WIND LOADS. Our structural
engineer, Peter Suden, has indicated that the weight of the pre-cast concrete
supports pose no problem to the existing roof system as the pre-cast units weigh
approximately 150-170 pounds, about the same as a man. The straps and pre-
cast concrete supports are sufficient to resist wind loading.
d. ABS AND PVC DWV PIPING INSTALLATIONS SHALL BE LIMITED TO
COMBUSTIBLE CONSTRUCTION AREAS. ABS and PVC piping is not
allowed by the mechanical specifications.
e. CROSS-CONNECTION CONTROL SHALL BE PROVIDED FOR POTABLE
WATER. Cross-connection control shall be provided at all code required

a. PORTABLE FIRE EXTINGUISHERS SHALL BE INSTALLED AS PER
UFC STANDARD NO. 10-1. Existing fire extinguishers currently service this
area as per code.
b. WHEN SERVING 100 OR MORE SPRINKLERS, AUTOMATIC
SPRINKLER SYSTEMS SHALL CONFORM TO UBC SECTION 3803 WITH
REGARDS TO SUPERVISION. This will be done.
c. PROVIDE SHOP DRAWINGS OF SPRINKLER SYSTEM BEFORE
INSTALLATION. Fire sprinkler shop drawing submittals will be forwarded to
authorities having jurisdiction for approval. (See Mechanical Specifications,
Section 15500, 1.04, B. 2.)
This concludes the A/E response to your departmental requirements. We trust you will find this material
satisfactory and will allow the General Contractor to obtain a building permit in the near future.
Should you have a question regarding any of the information presented here, please don't hesitate to call our
office.
