Re: Region V11 Juvenile Detention Center
P"

The Fire Department responded to a fire call at this facility on August 11,
1998. On our arrival, there was no fire present just some smoke. The
smoke came fro an air compressor in the basement that the motor
burnt out on. The smoke appeared to have traveled up some wire
chases that were not sealed'into the control room. t think that these
chases should have beers sealed. L talked to Blair and he said he had
not checked that. I was wondering who should be contacted about
getting this fixed if istirequired.
6 would suggest that they consider .installing smoke detection in the
basement. This was not required by the UFC, but as this situation
shows there could a fire in the basement for quite a period of time
with out anyone becoming aware of it provided the chases were sealed.

Reference is made to your leiter of November 26, 1997 and my previous letter of
November 21, 1997. My concern is with Items 3 & 4 which have to do with the ramp
and doors an the north side of the building. ten, _ _ _ _ ..
and that it is not a pubfic ramp. It is my u
�►+-s U� i iNi IctJ14� �� #c3! till i�mp is exiSunq
nderstanding that when considering
"nandicapped accessibility" related items, one mush consider not only the public bud
also the fact that some of the sheriff's deputies, clerical help, secretaries, cooks, etc. as
well as some. of the prisoners in the detention area may be handicapped._ Many, if
not most, of these people will be using these north doors and ramp. Handicapped
accessibility for future employees (as well as prisoners) is becoming a much more
frequently encountered issue. In this particular insance, i imagine you could possibly
get by an ASA challenge with a 36" wide ramp rathehan the 44" ramp required by
UBS Sections 1004,10 and 1007.2, iF the ramp met the slope and landing
requirements and IF the door(s) were recessed and the opening(s) wide enough to
allowsomeone in a wheel char to turn from the narrow ramp, approach and open the
door and enter the building on their own. The attached Figures 1 & 2 depict
reconstructing the ramp to the west to meet the UBC and ADA standardzl This doesn't
appear to create much of a problem in the area. The doors 23 & 25 (maybe 23 would
be enough) could be widened slightly and inset as shown

In the crrc�e of meeting 1 attend, we're told that personal ADA challenges rega din the

in the long run.
Thanks for your consideration of this possibility.

Entrances (211d Paragraph) indicates that: "When a building or facility has entrances
which normally serve accessible parking facilities, transportation fac] I [ifies, passenger
loading pones, taxi stands, public streets, and sidewalks, or accessible Interior vertical
access, then at least one of the entrances serving each such function shalt comply with
the accessible route prcwisions of CABOIANSI Al 17. 1, The entrances on the north
side of the building wiif, apparently, 'not.be accessible to the public as they will he
gated -off; therefore this entrance is left as the only one with any real public
accessibility. A handicapped accessible ramp could be constructed to the south of the
new steps relatively easily. I assume the vehicle parking on this easy side will be
converted to one handicapped stab and three visitor parking stalls.
Z -- Shts. SD -1, SD -2, SD -3 & A-2 — Your 1994 UBC Analysis (Sht. A-2) indicates
there ate 51 occupants of the building; therefore. at least 2 exits are required from the
building. You have 4 entrances/exits from the building. Sic, 1103.2.3 - Accessible
Entrances indicates that: " At least 50 percent of all entrances shall be accessible, ,,
Seg. 1,104.1.1 - General indicates that: When more than one exit is required from any
accessible space, each accessible portion of the spare shat! be sewed by nit fess

one of the entrance/exits on the north side of the building should be handicapped
accessible.

cle ot the building is intended to be. The above referenced UBC Sec.
would have to be at least 44 inches wide at the doors.
UBC Section 1007.2 Ramp Widths, states that.- "The width of ramps shall be
determined as specified in Section 1003.2, but shall not be less than 44 inches, except
as specified herein. Ramps serving an occupant load of 49 or less shall not be less
than 36inches in width." The total occupant load of 51 is used when makino this
uu��rminaz�on or wnetner the ramp has to be 44 inches dor 361nches) wide.(See
attached EXAMPLE I -- Ramp VVidth which comes from the UBC bode Applications
Manual - Questions & Answers.) It therefore appears that this ramp should be at feast
44 inches wide.
However, even with a 44 inch wide ramp, there ars stip problems with the two doors
and their landings. UBC Sec. 1007.4 -- Landings (2rldparagraoh) stades that- "Doors in

rs and landings as shown do not meet this requirement. �Note that this
o�cilr�n s requirement for doorway clearances at ramp landings a�-e more stringent than
those in Sec. 1004.10 - Landings at Doors.}
CABO/ANSI Al 17.1 also has requirements for handicapped access maneuvering
clearances at doors. See attached Fig. B4113.6 (b) and ( c) from this CAB,O/ANSI
manual which indicates that wider landings are necessary at doors depending upon the
approach to the door, the door siring and the type of closer and latch on the door.
Obviousiy, these depictions do not fake into account the requirements. of Sec. 1007.4 -
Landings set forth in the preceding paragraph.
4 — Shts. SD -2, SD -3, A-2 & �4-4 — UBC Sec. 1007.3 -- Slope, indicates that the ramp
nope shall not be greater than 1 unit vertical in 12 units horizontal- therefore, one or
both cfi the ramps on the north side of the building should have a slop� no steeper than
1.-12. Section 4.8 of CABO/ANSIA'� 17.1 also shows the need dor ramp slopes of 1 : 1 2
or fess except for short rises of 3" to 6" where steeper stapes can be used.(See
attached Sic. 4.8 and drawings of ramp slopes �rnm CAB�lANS1,) Nate their
requirement that a ramp landing is required if the rise is larger than 30`.
5. — Sht. A-2 & M-3 -- The 94 UBS Analysis on Sht. A-2 does not mention that the
building will have a sprinkling system. Sht. M-3 shows a de -tail of a Fire Sprinkler
'Riser Diagram and the Specifications include specs. for a Wet Pipe Fire Sprinkler
Protection System, so 1 assume the project incudes an au�flma#ic fire sprinkling
pg -2
system. UBC Section 904.2.6 - Group I occupancies of co�r-s�, requires an
duLuinauc spnntuer system. Will the existing 2" waterline entering the building provide
enough water for a sprinkling system or are you going to have to bring in a 6 "
connection from 2"d East St? Also note the Fire np-nartrmanfc n"oq
attached plan review.
6 — Shto A-2 & A-5 — You could use fh� EXCEPT�QN ��sted in UBC Sec. 308.2.2.2
Group !, Division 3 Occupancies if yflu wanted to use 2x4s & gypboard rather than 8"
CMU's in the Administrative portion of the building. The fiFe sprinkling system could
provide the I -hr. fire rating-
7—Sht.A-2—Is Dressing Rm 114formenlwomenorboth? UBCSection2902.3
indicates that: "Separate facilities shall be provided for each sex when the number of
employeus exceeds four. Such toilet facilities shall be located either in such building
or conveniently in a building adjacent thereto on the same property." Are there fewer
than four employees? Or do you consider the toilet facilities in the adjacent
Courthouse to be `'convenient" enough?
8 -- Sht. E-3 -- 11Vhy aren't there lighted EXIT signs over Doors 19, 2

A 50 percent greater multiplier is used dor stairways
than for other exits such as corridors, rams and exit
passageways since level and ramped egress facilities accom-
modate about 50 percent more people than do stairways in the
same time period. It is evident that the speed of exiting on the
5CdifS i5505211tially less than the speed of exiling on level or
near -level surfaces. This 'is due to the force reduction in normal
snide, as [he lengths of stride on a stair mist coincide with the
stair run. A sturdy of this difference shows that the stair width
needs to be increased by 50 percept moue the width used for
level or ramped exiting. Tie 0.3 -inch -per -person (7.&2 mm)
multiplier is based on 2 2 inches �559 mm) of exit stair width far
an occupant toad of 75 persons, The 0.2 -inch -der -person (5.08
MM) rnultipher [5 based ars 22 inches (559 mm) of level or
ramped exit for an occupant load of 100 persons. The choice
of 75 instead of the traditional figure of 60 persons applied to
stair capacity is based on improved efficiency of the 7 -to -1 1
Mair -riser -to -run ratio.
The relationship of exit width to occupant load is based on
an egress flow -time performance of approximately 3.5 min-
utes. For example, a rninimum stair width of 44 inches (11 -18
mm) is credited with a capacity of 441.3 = 147 persons, and
44 -inch (1118 mm) corridor i5 credited with a capacity of
44/0.2 = 224 persons. This means that a sustained crowd o€147
persons on a 44 -inch (1118 mm) stair or 220 persons in a
44 -inch (1118mm) corridor carp pass a point on the stair yr in
the corridor in approximately 3.5 minutes.
■ Please explain how stairway width is determined
■ based an a floor"s having access to two stairways?
■ Section 1003.2 states, "The total width of exits in in-
• ches (mm) shah not be fess than the total occupant
load served oy an exit multiplied by D.3 (7-.62) for 5tairways and
0.2 (SAS) for qtIle!" E?CtfS €SOI' I e55 than SpE'CffleCI eISE'WheCL 1n CAIS
code." It further states, "Such width of exits shafl be divided ap-
proximately equally among the separate exits." Thus, for exam-
ple, it two stairways serve a total occupant toad of 400 from the
top story of a multistory building, the 4vidth of each stairway is
based on an occupant ioad of one half o{400 = 200 occupants,
The required width is 200 x 0.3 = 60 inches = 5 feet 0 524 mm}.
�.
When dealing w'th the subject of the mr`nimuMwid#h of stair-
ways addressed in Section 1006.2, the application is d-ifferent..'
The first sen tence in this section states, "The minimum stairway
width shall be determined as specified in Section 1003.2 but
shall not be less than 44 inches (I 718 mm) except as specifiled
herein." For the application of this provisioil, the occupant load
being served is intended to be the total occupant load of the
fl oo r th at the stairways are serving.-rhus, -vv lien a given fl oo r re-
quires two exits and the occupant load of the floor is 50 or move.,
each of the stairways must have a 111inimum width of 44 inches
(1118 mm).
Section 1003.3

shall be placed distance apart equal to not less than one half the
