This memo report presents our findings based o n our visual inspection and on-site

structural damage assessment for the above subject schools in v i e w of the aftermath
o f the earthquake which occurred o n August 08, 1993.

SCOPE OF WORK

The scope o f our investigation work performed for this structural assessment is based
upon t h e following.

1. Assessments are based o n visual inspection. A n initial "walk-through" site visit


w a s performed for the purpose of orientation and t o obtain a general impression
o f the building structures.

2. Due t o t h e limited time frame allowed, no detailed analysis and evaluation of


t h e structural system was performed.

3. Our preliminary assessment provides a qualitative evaluation in comparing


between t h e pre-earthquake and post-earthquake load resisting capacity o f the
existing structures. The identification o f structural deficiencies in the buildings
with reference t o governing present codes are n o t within t h e scope of this
report.

SUMMARY

In general, there are n o major structural damages observed o n t h e main structural


elements o f t h e buildings. Based o n our visual inspections w e are of the opinion that
the overall structural framing system o f the buildings showed n o visible signs o f
structural failure, or indications of any possibility of an impending collapse.

FINDINGS AND RECOMMENDATIONS

The findings and recommendations of our structural assessment for each of the
individual schools listed under the above subject are found in the attachments t o this
report.
w
CONCLUSION

~ l t h o u g hsome o f the bulldings has sustained damages, w e m a y conclude f r o m our


t h a t t h e lateral load resisting elements o f the building have n o t been
s i g n i f i c a n t l ~affected. Structural repairs as recommended should start immediately in
order t o restore t h e structural integrity o f t h e buildings t o its pre-earthquake condition.

LIMITATIONS
The findings a n d recommendations presented herein are based o n limited information
and visual observation obtained f r o m assessment o f existing site conditions.

Our services consist only o f preliminary visual on-site assessment and engineering
judgement made i n accordance w i t h standard engineering principles and practices.

Re: Earthquake Damage Assessment for D.O.E. public schools

Hafa Adai Governor:


We are pleased to submit the attached visual assessments of the 17
D.O.E. public schools per your request. After your review and
approval, we recommend distribution of these assessments to all
relevant interested parties. Our assessment team and I are
available if you wish to discuss our findings in more detail.
If you require additional assistance regarding these schools or
other public facilities, we are prepared to provide more detailed
and comprehensive review and analysis for any of the public
facilities you deem necessary. Please keep in mind that our visual
assessments are preliminary in nature, and more detailed analysis
and design repairs will be required to implement any mitigation
measures contemplated in our assessments for the long term
viability of Guam's public schools.
We thank you for the opportunity to assist you in protecting the
children and the future of Guam.

Assessment of damages due to Earthquake of August 8, 1993
Dear Dr. Quitugua:
Our summary of the earthquake damage and assessment during our
inspection on August 20 and 21 are as follows:
1. The structures sustained very minor earthquake damage. The
observed damage had negligible effect on the ability of thq
primary structural system to resist vertical and horizontal
loads. We did not observe any damage that poses a hazard to
the occupants.
2. We observed hairline cracks in the beams, roof slab and
masonry wall joints. Most of the cracks were existent prior
to the earthquake as evidenced by dark mildew and water stains
around the cracks.
We have not made a structural analysis of the structural system and
therefore have no opinion on the ability of the structural system
to resist Code specified horizontal and vertical loading (either
before or after the earthquake). Our opinion is limited to a
comparison of the load resisting capabilities before and after the
referenced earthquake.
Repairs should be made using materials specifically recommended by
the manufacturer for use in the repair of structural concrete. The
repair work should be performed by skilled workmen. The repair
procedures should be approved, and monitored by a professional
engineer.

Our summary of the earthquake damage assessment during our
inspection on August 20, 1993 are as follows: t
The structure sustained minor earthquake damage. The observed
damage had negligible effect on the ability of the primary
structural system to resist vertical and horizontal loads.
The damages we observed are as follows:
1. Wall cracks were observed at the Office Building, Library and
Classrooms. These are minor cracks and majority appear to
have existed before the referenced earthquake. Also minor
vertical cracks were observed in the Cafeteria Bathroom walls.
2. Cracks on top of masonry columns supporting beams along the
hallway.
3. Spalled upper roof deck due to rebar corrosion (non-earthquake
related).
4. Temporary wood structures slightly shifted laterally from the
masonry foundation. No distress to the structure was
observed.
We have not made a structural analysis of the structural system and
therefore have no opinlon on the ability of the structural system
to resist Code specified horizontal and vertical loading (either
before or after the earthquake). Our opinion is limited to a
comparison of the load resisting capabilities before and after the

Assessment of damages due to Earthquake of August 8, 1993
Dear Dr. Quitugua:
Our summary of the earthquake damage assessment during our
inspection on August 20 is as follows: t

1. Overall, the campus structures sustained very slight damage as


a result of the August 8 earthquake. Except for the items
listed below, the damage we observed is not, in our opinion,
significant enough to impair the structures' abilities to
withstand vertical and horizontal (earthquake/typhoon)
loading.
2. Loose fragments of spalled concrete and masonry were observed
at numerous locations throughout the campus. Access to these
areas should be restricted until this loose material, which
represents a falling debris hazard, can be removed and
repaired.
3. Four areas of concern are:
a. The corner column between Rooms BlOO and B101. Cracks
observed below the beam column joint on the exterior and
interior faces of the column. The loose concrete should
be removed to allow a closer inspection of the column
prior to repair.
b. The corner column outside Room A105. Cracks were
observed on the exterior and interior faces of the
column, below the beam column joint, and concrete has
spalled at the cracks. We recommend that the beam be
shored, and the loose concrete removed to allow a close
inspection of the column prior to repair.

c. The corner column outside of Room A109, and the walkway


slab outside of Room A208 above. Cracks were observed on
the exterior and interior faces of the column, below the
beam column joint, and concrete has spalled at the
cracks. A diagonal crack, portions of which were present
before the earthquake, was observed on the top of the 2nd
floor walkway slab. We recommend that the beams framing
into the column, and the slab, be shored, and the loose
concrete removed to allow a close inspection of the
column prior to repair. The crack in the slab should
also be investigated to determine its depth, prior to
repair. The hallways between the restrooms and A109, as
well as above between the restrooms and A208, should be
restricted from access. In addition, the CMU shear wall
outside of Room A109 displayed a horizontal shear crack
down its length under the top course of blockwork. This
crack should be repaired immediately.
t
d. The exterior wall outside of the guidance office. This
is a CMU infill wall, which does not have adequate
connection to the beam above. A permanent displacement
of over an inch was observed at the top of the wall,
indicating that the wall moved freely during the
earthquake. No damage to the wall was observed. We
recommend that the wall be attached to the beam above
using an appropriate detail, to provide adequate bracing
in the event of future earthquakes.
The damage we observed in the rest of the structures is as follows:
1. Most of the cracks we observed were between the concrete
framing and the CMU infill walls. These cracks do not
significantly affect the structure. However, they should be
repaired immediately, as they may cause concern among the
occupants of the structures, and because they allow water to
enter the walls with exterior exposure. The encroaching
moisture can cause the embedded rebar to rust, leading to
spalling and further corrosion, resulting in more damage.
2. Some minor cracking was observed in some of the frame members,
notably in the overhanging walkways and outdoor walkway
canopies. These should also be repaired for the reasons
stated in item #1 above.
3. Cracking and spalling was observed at many of the expansion
joints, which was the result of the structures butting against
each other during the earthquake. This damage should also be
repaired immediately to prevent corrosion problems.
August 22, 1993
Dr. Franklin Quitugua
Page 3

4. Some loose blockwork was observed in the CMU walls in the


gymnasium locker room and offices. These loose pieces should
be removed immediately, as they are a falling debris hazard.
We recommend that access to these areas be restricted until
the removal of debris is completed.
We have not made a structural analysis of the structural system and
therefore have no opinion on the ability of the structural system
to resist Code specified horizontal and vertical loading (either
before or after the earthquake). Our opinion is limited to a
comparison of the load resisting capabilities before and after the

Assessment of damages due to Earthquake of August 8, 1993
Dear Dr. ~uitugua:
Our summary of the earthquake damage assessment during our
inspection on August 20 are as follows: t

1. The structures sustained minor earthquake damage. The


observed damage had negligible effect on the ability of the
primary structural system to resist vertical and horizontal
loads. Areas or items that pose a hazard to the occupants are
noted below.
2. Loose fragments of concrete or masonry should be removed.
Restrict use of areas where loose fragments occur until
repairs are completed.
3. The entrance walkway from the parking lot to the cafeteria had
been cordoned off prior to our inspection due to the spalling
plaster on the CMU walls. Keep the area secured. Although
damage is minor and repairable, the stability of the original
structure is questionalbe. Further structural investigation
will be required and proper repair procedures determined.
The damages we observed are as follows:
1. Spalls in the main off ice walls and construction joint cracks
in the CMU walls.
2. Spalls on the concrete roof slab, at the expansion joints.
3. Spalls on the concrete roof slab bottom around the pipe
columns of covered walkway.
4. Adjacent to Room 5 over the walkway, a portion of masonry
infill panel between the walkway roof and main roof shattered
leaving a hole approximately 8" x 18". This damage occurred

because the infill was constructed continuously across an


expansion joint. No reinforcing was visible in the damaged
portion of the infill.
5. In the classrooms, cracks were observed at masonry wall
corners, horizontal vertical joints, and window sills. Spalls
were observed in the masonry, usually at the column joints.
These are typical of damage all throughout the building
between Rooms 1 through 24. Roof slab cracks were observed in
several classrooms but these are old cracks not related to the
referenced earthquake.
6. Hairline cracks were observed at the exterior walllbeam joint
of Room 28 and interior wallslbeam of Room 30.
7. Masonry wall corner cracks and exterior masonry spalls were
observed at the Library and adjacent classrooms. Several of
the cracks have loose fragments of masonry blocks.
t
8. Diagonal shear cracks in the masonry walls were observed on
Room 102/103 and joint cracks in stepped diagonal pattern were
observed in Rooms 105/106.
We have not made a structural analysis of the structural system and
therefore have no opinion on the ability of the structural system
to resist Code specified horizontal and vertical loading (either
before or after the earthquake). Our opinion is limited to a
comparison of the load resisting capabilities before and after the
referenced earthquake.
Repairs should be made using materials specifically recommended by
