Re: Owner Proposed Alternative Design Criteria for Voluntary, Partial Seismic Upgrade of Calais Multifamily Bldg
Enclosed please find alternative structural design criteria for voluntary, partial seismic upgrade of the
Calais building per City of Edmonds Bldg Dept submittal requirements. As you know, property owner Monte
Clouston is willing to perform a selective seismic upgrade the circa 1985 multifamily bldg to increase
occupant/public safety & property resale value. However Monte indicated it is too costly & impractical, to
fully comply with IBC 2003 design, detailing & inspection requirements. Therefore, he is seeking City of
Edmonds Bldg Official review/approval of an alternative design criteria, as allowed in IBC 2003 Section
104.10 (Modifications) & Section 104.11 (Alterations). The Owner proposes a limited scope, voluntary,
seismic assessment & seismic rehab based on a combination of UBC/ASCE 31-03 (Tier 1) seismic assessment
criteria, and 1982 UBC/IBC 2003 seismic design criteria, though the alterations would (most likely) also meet
all (6) exception criteria of IBC 1614.3 (Alterations, Exception). To elaborate, the Owner proposes the
engineer (Mark Heinzig, PE) to:
• perform a limited scope, non-invasive structural condition survey of the building,
Evaluate the existing building's lateral force system design against the historic 1982 UBC criteria, a
ASCE 31-01 (Tier 1 screening criteria) & engineering judgment.
Afterwards, those portions of the building's existing lateral force resisting system which the PE observes
(or suspects) to be a historic structural design omission or as -built deficiency which the PE believes might
pose either a life safety concern under either a 1982 UBC or IBC 2003 prescribed seismic (or wind loading)
event shall be mitigated (to meet the greater of the 1982 or IBC 2003 seismic strength design criteria).
However, due to the building's age, construction type, in-place architectural features, current occupancy &
projected rehab cost, the owner indicated he cannot fully meet the IBC 2003 seismic drift limits, nor all
associated detailing, special inspection & testing requirements required of new wood framed construction
under the IBC 2003. To require such would be an economic hardship & result in no voluntary upgrade at all.
We believe the proposed "alternative design & method of construction" outlined on the following pages
either meet the design intent of the IBC 2003, or at least is equivalent in terms of quality, strength,
effectiveness, fire resistance, durability & safety. Please note, the outline below seeks to address not only
proposed alternative design criteria, but also includes a proposed construction submittal & inspection
program, and a proposed mechanisms for addressing construction phase issues that may come up.

i. Engineer site visit/each week
ii. Engineer report, field photos, PE stamped.
iii. PE stamped Structural Observation reports shall be submitted separately from structural inspection
reports, and may be provided to City of Edmonds upon request.
IX. Structural Special Inspections:
a. Owner Requests Bldg Dept provide a determination on these items related to Inspection:
• Owner requests Bldg Dept Official to allow E.O.R (Mark Heinzig, PE) rather than 3`d party inspection agency to perform
all periodic & continuous structural special inspection summarized in Section IX, item b (next page), except for those (SI)
inspections to be performed by the Geo -Engineer. This is prudent & economical, since Mark is the E.O.R., and will be
infield for periodic structural observation on behalf of Owner.
• Owner requests Bldg Dept Official to not designate Type 2 & 3 shear -walls as high-strength shear -wall, as would be
otherwise be required if IBC 2003 Section 1707.3 were applied to this project. This would avoid triggering costly
(continuous or periodic) special inspection requirements for install of a majority of the shearwalls upgrades.
• Owner requests Bldg Dept Official E.O.R. (Mark Heinzig, PE) to perform periodic special inspection of high strength
shear -walls Type 4, 4b & Type 5 shearwalls, rather than continuous special inspection. E.O.R. is comfortable with this,
+ Owner requests Bldg Dept Official to arrange for daily (3 pm) City. of Edmonds Inspector review of all existing insulation,
fire stopping, now fire caulking (around exposed wiring & plumbing) and other non-structural items (left in place in
perimeter wall cavity atter shearwall rehab). But, if the City Inspector doesn't arrive by 3 pm, the Owner wants the Dept
Official Official to allow E.O.R. (Mark Heinzig, PE) to perform this task as aperiodic special inspection. This would
allow the Contractor to reinstall exterior sheathing after E.O.R. performs special inspection. This is prudent, since the
E.O.R. will only allow concurrent upgraded of (2) staggered shearwalls on each building's exterior elevation, at each floor
level, to avoid building structural vulnerability. If instead, the Citywere to demand City inspection of the cavity area of
each disturbed (existing) shearwall being upgraded (prior to new PW sheathing install), it would require the City inspector
make several visits each day to the site, and require the Contractor to wait for inspection to move forward, several times
during the day. This would be a very time.consuming & costly hardship to all patties involved, including the City.

Structural Special Inspections: (continued)
Owner Requests Bldg Dept provide a determination on these items related to Inspection:
Owner requests. BIdg Dept Official to allow Owner to reinstall existing (disturbed) insulation instead of requiring
`replacement insulation. FYI, the Owner doesn't want to `interrupt' or damage the existing `vapor' barrier on the heated.
side of those perimeter shearwalls (Type 1, 2, 3) where the existing gypsum surface won't be disturbed or replaced. But, if
the City of Edmonds deems it necessary (to add add'I insulation at the disturbed sbearwalls), the Owner is willing to install
%" rigid insulation (R 3.3) in the cavity of the upgraded perimeter shearwalls (adjacent to the unheated side). However, the
Owner would also requests that the E.O.R be allowed to perform a periodic inspection of these assemblies (with
supporting photos) and subsequent install of the PW shearwall panels if the City Inspector doesn't arrive at the site at 3 pm
(for inspection purposes). (Please not, the E.O.R. would also confirm the proper install of existing/new fire stopping, new
fire caulking (around exposed wiring & plumbing) and other non-structural items (left in place in perimeter wall cavity
after shearwall rehab) at this time, if the City Inspector didn't arrive by 3 pm.)

X. Processing "Post -Permit" Field Repair Details
a. Sources of post -permit repairs:
i. Contractor field substitutions.
ii. Contractor Field Install Errors.
iii. Concealed As -Built Conditions.
iv. Conflicts between Design. & As -Built Conditions
b. Proposed Mechanism for E.O.R. handling post permit field repairs:
i. Owner requests Bldg Dept to make a determination that E_O.R. (Mark Heinzig, PE) may provide
design & PE stamp (minor) engineered field repair details (to match as -built conditions) for
contractor use, without waiting for City .of Edmonds review & approval. F.O.R. shall document &
photograph all changes in weekly engineering reports, and provide copies of the PE stamped
engineered details, (& supporting talcs, if necessary).
ii. However, if the City requires all `minor' field changes to be incorporated into PE stamped revised
plans, special inspection reports, and structural observation reports, and submitted to the
City for review/approval nrivr to construction use, the delay would be a hardship on the
Owner. This situation of `waiting' for City approval on `field repair details' would become
problematic for upgrade of existing perimeter shearwalls of an occupied building, as
previously discussed in Section V, Part N, item 4.
e. Proposed Method for E.O.R. handling post permit field repairs:
i. Engineer review/evaluate of Contractor substitutions.
ii. Engineer PE stamped detail of approved substitution, and Contract install.
iii. Field repairs documented and photo in weekly observation reports
iv. E.O.R. shall document & photograph all changes in weekly engineering reports, and provide copies
of the PE stamped engineered repair details or `as-builts', (& supporting tales, if necessary), post
construction.
XI. Proposed City of Edmonds Inspections
a.. Structural inspection for Seismic Rehab
i. Grade bm Foundation reinforcement at Grid 6, 7
ii. Strip Footing at Grid N
iii. All type 1, 2 3 Shearwalls (low strength, not high strength)
iv. Fire -stopping; Fire blocking, and existing insulation (see item xx
b. Building Envelop Repair Inspections
i. Design, construction & inspection per EHB 1848 & Bee Consulting Engineers
ii. Periodic inspections by Bee Consulting Engineers
iii. Bee Consulting to coordinate with City Inspector for Inspection
1. Lath Inspection
2. Flashing, Counter Flashing
3. Vapor Barrier

XII. Owner Requests Bldg Dept Official determination on these additional (mise.) items:
• Owner requests Bldg Dept Official assistance in finding an AC308 compliant, post installed adhesive anchor which is ICC
ESR listed (for use in cracked concrete and/or for resisting TBC 2003 seismic forces) as per Jerry Barbera's redline plan
review submittal requirements or waiver of that requirement. FYI, Owner/Engineer spent (4+) hrs looking for such a
product on Internet, but found none. The closest product (Hilti_Hy-500-SD) is reputed to be a post -installed adhesive
anchor meeting AC308 compliance, but it will not be available from Hilti until Spring of 2007. Owner therefore
recommends `waiver' of this submittal requirement, and requests Bldg Dept authorization for install of a Simpson SET
post installed adhesive anchor (Simpson SET epoxy system or Hilti HIT HY-150) which is AC58 compliant, and ICC ESR
listed (for use in cracked concrete and/or for resisting IBC 2000 seismic forces, though not IBC 2003 seismic forces).
• Owner requests Bldg Dept Official allow E.O.R. (Mark Heinzig, PE) to perform periodic special inspection of adhesive
anchors, rather than continuous special inspection. FYI, this is allowed for post installed adhesive anchors meeting ICC
evaluation AC308 criteria (based on test data submitted in accordance with Section 11.24 of AC308). And, although we
can't find any anchor meeting those criteria, we'd propose periodic special inspection be allowed for post installed
adhesive anchors meeting AC58, noted above.
X111. Supporting Exhibis:
