Dear Ann Bullis:
This is a plan review of the:
Project Name: Stevens Wound Healing and HBO Clinic
Plan Review Np: 1145-208 (Your Plan Check Number is TI 2008-0058)
1 have determined the following general criteria that apply for this project:
NON-STRUCTURAL DESIGN CRITERIA:
Occupancies: Group B, Clinic; Control Area for Oxygenation Chamber; Outdoor Ox Tank
Construction: Type II -B, Fully Sprinkled; Group U, Type 11-13 Outdoor Oxygen Tank
Stories: Two; Height: M 25'; Floor Area Involved: 1888 sq. ft. (given}, Tank — Unknown
Codes Used: 2006 International Building, Fire® & Mechanicals Codes, UPC & WA Amends.
Valuation: $350,000.00
This letter report provides a review of relevant issues related to a new medical clinic procedure in your
city. The review has revealed some areas where more details or further explanation is required in order
for me to conclude that they do comply with the IBC, IFC & IMC provisions. Although the report is
addressed to you, Ms. Bullis, and is written as "advisory recommendations", the designers need to
address them and resolve the issues unless you find otherwise. Some comments may require a
change of plans and/or specifications. In order for you and me to quickly determine that the issue has
been solved, it would be appreciated if they would show a cloud around the change. If they dispute the
issue, they should provide their analysis of why they are correct in writing in order for you and me to
address them and agree with them or provide further argument or questions.
Building Code Comments (Section Numbers are for the IBC, u.n.o.)
1. Analyzing the hazards & mitigations. IFC Chapters 27, 30, & 40; IBC Sections. 304 & 307:
a. The electrical code for WA is the 2005 edition and needs correction on Sheet T0.00.
b. A Material Hazards Data Sheet needs to be available on site & a Hazardous Material
Management Plan may be required by yourFire Marshal. Secs. 2701.5.1 & 2703.4
c. IFC Chapter 30 gives the general criteria for compressed gases in tanks and other
containers. There are provisions in IFC Section 3003 for marking the tank and those
details need to be accounted for on the plans or specifications.
d. Depending on Oxidizer class in Table 2703.1.1(1), Oxygen quantities used in HBO
chambers may force them to be on the 'f=t Story only. IFC Table 2703.8.2. Provide
Calculations. Note: one non -hazardous area is always one of the control areas.
e. Note that a control area regardless of which floor it is on, has to be enclosed by a
one-hour protected walls, floors and roof/ceilings. Those structural members which
carry the control areas also have to be protected to onehour construction including
bearing walls and/or columns below.

f. It could be that the framing shown on Sheet T3.10 is either the existing protection
system or a proposed one. Either case, it needs to be detailed assuch. No column
protection is shown, however.
g. However, the walls have to be protected as fire barriers, which will include onehour fire
assemblies. Sections 414.2.1 and 706.3.7 and Table 715.4. There has to be a complete
separation, which means that the main walls around the space have to extend into the
attic areas and top of wall protectionrthrough penetration fire stops will be required.
Walls 21T3.10 could comply, if the "structure" above it is actually the underside of the
roof deck. Sections 706.5 and 713.1
h. Glazing in the doors into the "corridor' (actually "exit") enclosurecan't be larger than 100
sq. in. which will require a change in Door * 1. Section 715.4.4.1
i. The suspended ceiling appears to be screwed into the grid rather than layin type on
Detail 11T3.10. So the general wire bracing isn't necessarily needed although it won' hurt
to have it.
j. IFC Sections 2703.5, 2703.6 and 2703.7 have requirements for signs for the oxygen
area storage that should be enumerated on the plans.
k. The size of the outdoor Oxygen Tank is not given, so it is difficult to judge if the amount
of oxygen in it complies with either the performancebased design alternative of IFC
Section 2701.3, or relevant portions of IFC Chapter 27. It needs to have a design.
1. There is an 8' high CMU fence proposed around the outdoor Oxygen Tank for blast
containment of adjacent property. At the very least, a measure of the level of this blast
should be stated so that there is some viable criterion fora structural designer to use.
m. Although it is already far enough from property lines and buildings, the clearances from
the Oxygen Tank on Sheet TO. 10 from various structures by IFC Table 3504.2.1 needs
to be shown as Fat least to a building, property lines or public ways which trumpsthe
Beacon-Medes Medical Gas Design Guide shown thereon. Depending on the tank's
quantity, that dimension may have to be a larger distance by IFC criteria.
2. The arrangement of the interior Clinic boundaries within the 2nd floorlT1.10 seems a bit
strange. Why wouldn't the entire space between Lines, 7.5 and 8 be counted for the number
of occupants including in the waiting room? A reevaluation of the occupant loads seems to be
required, Section 1004.1
3. Another exit sign needs to be placed at the intersection of the "fact" of the "L' -shaped corridor
on the 2nd floor approximately at the intersection ofGrids C5.3 and 4.8, pointing east.
4. How heavy are the Hyperbaric Oxygen chambers? The floor they rest on should be reviewed
for structural ability to carry the chambersincluding a surcharge loading of a number of
people in them including a safety factor. Sections 1607.3 and 1607.4.Lateral restraint is also
needed. Section 1613.1
5. The connections for the outdoor oxygen tank and the above grade piping to them need to be
justified for seismic resistance.
6. The exact way that the high pressure tank shown in Cabinet Section 151T7.00 is secured
especially for the bottom of it during an earthquake is needed.
7. The exact method of tying down the roof equipment against lateral movement i needed.

8. A statement of special inspection is necessary for the connections of certain structural items.
IBC Sections 1705.1, 1705.2, and Section 1705.3 (because exception # 1 doesn't seem to
apply when all three conditions are included in total.)
9. Seismic restraints for the piping need to be shown. IMC Sections 301.15, 305. 1, UPC items
below, and the '05 ASCE 7 Sections for HVAC and Piping.
10. The contractor has to provide a statement of responsibility prior a permit is given. Sec. 1707
11. Details are needed for oxygen piping inside the building needs to be specified to determine if
it complies with UPC Section 1310.19 and most subsections of 1311, et seq.' (Note that these
are actually reprints from NEPA Standard* 99).
12. Also, the second floor Plumbing Plan Sheet M2.0 states that the plumber is supposed to
choose the connection between the oxygen plpng and the Hyperbaric Chamber. It would
seem that these specialized connections would be required to be sanitary and tight and they
should be directly specified on the plans. UPC Sections 1314 and 1315, et Seq.
13. The size and spacing of the pipe supports need to be given too. UPC Section 305
14. Details of through -penetration fire stops are necessary. IBC Sections 712.3 and 712.4 and
IMC Sections 302.2 and 1105.1. If they are deferred submittal items, they need to be listed on
Sheet T0.00.
CLOSING
As stated in the beginning of this letter, the designer should revise the plans and specifications and
resubmit them with a letter explaining their rebuttal and indicating on whichsheet or detail the
correction may be found. If the engineer or architect disputes some of my comments, they or you
shouldn't hesitate to call me and discuss those issues.
Thank you for the opportunity to be once more of service. The invoice for this service and the plans
and specifications will follow under separate cover after the recheck is done.
Sincerely,
