- Inspection
of the rear, second level, cantilevered decks. Cantilevered joists
showed evidence of wood rot, with the damage ranging from total decay
at the exterior bearing wall, to little or no damage to some of the
joists on the same deck platform. Recommended solutions: A) Remove all
extended ends of the deck joists, remove original blocking between
original joists. Replace blocking with continuous rim joist (under
threshold of sliding glass door), provide continuous flashing under
threshold of new SGD and over new pressure treated rim joist. Install
an engineered, end wall, designed with load bearing capability and
finish it with matching stucco. Other possible solutions would be to 1)
install a new end header beam; support it with a concrete footing, and
pressure treated wood or steel post, then run new joists parallel to
the rear, outside wall, from the existing, stucco, demising wall to the
new beam, described above. Or 2) install steel fabricated mounting
brackets on new end header beam (same as above) and on existing
masonry, stucco, demising wall to connect a diagonal post from the
outside corner of the new header/beam back to the outside wall of the
unit. We view these options as less desirable because the post would
land in an awkward position, and both #1 and #2, above are inconsistent
with the established architectural flavor of the buildings.
- Evaluate
the various exterior architectural elements of the buildings. A) Wood
siding: horizontal, diagonal, or vertical boards. After much
discussion, it was decided that, the siding should be installed in a
vertical pattern with vertical trim to accent the two windows in each
second level section with siding. The siding should be no wider than
nominal 1 x 6 (5 ??). (See Further Recommendations, below, for more
comments on siding and details.) B) Wing walls and broken roof lines at
the eave ends. It was decided that the existing roof lines were good,
and added interest to the front elevation. It was also decided that the
second level wing walls were an interesting architectural element and
should remain. C) The third element in this area of the building was
the existing 2 x 2 lattice work that ran full length, in front of the
second level window. It was decided that while the lattice detail added
interest to the front elevation, it was determined to reduce the height
of the decorative lattice by approximately two-thirds. It will now run
from the bottom of the wing walls up, to just under the sill height of
the window. This will tie the wing walls together, making it a more
stable group of elements, while allowing for maximum natural light with
no outside obstructions.
- Further Recommendations:
After a more thorough overview of the building fa?ade, with its
proposed changes, we would recommend two items that, in our opinion
would make the exterior more pleasing and consistent. A) Eliminate the
siding on the short extended walls, at the second level. They are
currently done in diagonal siding with wide trim accents on each side.
We believe that these two small areas should be done in stucco to match
the rest of the end wall elevation. Keep the trim boards as they are,
and replace the siding with stucco to match. B) Construct the second
level wing walls, on each side of the single window, with Stucco and
wide trim. We do not recommend using siding for this detail.
Inspection Of Mid Rise ? 24 Unit Buildings
- Inspection
of several instances where the surface of the concrete columns and
slabs has fallen away, to reveal in some instances, exposed steel
reinforcement. After inspecting several locations where this condition
was evident, it was determined from the visual evidence, that the loose
concrete should be removed, the area should be cleaned, with special
attention paid to the exposed steel reinforcement. The exposed rebars
should be thoroughly cleaned with a wire brush (free of any
contaminants; grease, oil, etc.). A concrete primer should be applied
to all surfaces where original, unstable concrete has been removed. The
bases of each column should be modified to add 1 ?? of thickness, from
the floor/base up 48? (6? above top of new railings) as protection for
the existing steel reinforcement bars. The contractor shall check all
existing surfaces for loose or patched concrete. This should be removed
in the prescribed manner, above. The contractor shall roughen the
existing surface to assure the best possible bond. Replace the damaged
concrete with new, expanding, hydraulic cement, and finish with a
weathertight exterior finish product, consistent with the existing
finish of the rest of the building. Use small aggregate, not to exceed
3/8?, and use ?pencil vibrator? to vibrate vigorously, while making the
pour. It appears that the structural integrity of the base structure is
in good shape. By taking these measures now, they will help to protect
that original structural design.
- Exterior steel
railing and handrails. Note: the existing top grab rail is 2 x 8 wood
with the top edge shaped with a bull nose detail. The existing rails
are currently in various condition in regard to appearance and
stability. The existing railings do not meet current building code
requirements in regard to height above the floor/deck surface, open
space between the vertical balusters and strength to resist the
required horizontal loads. Several locations were observed where the
handrails and railings were very loose and/or unstable. Further
investigation of the conditions revealed that in many instances the
steel support plates have rusted through and can no longer support the
steel vertical balusters that are welded to them. In some cases, the
connecting hardware used to connect the end of the railing to either a
concrete or masonry wall or column, has worked loose and no longer
provides the required connection. There are also instances where the
end of a particular rail or railing is connected to exterior wood trim
details. Several of these railings are loose and in need of repair or
replacement. In several locations, it was noted that the wood top rail
was soft and spongy; indicating wood rot. It was also observed that
where the original steel mounting plates have been removed from the
floor slab, there is damage to the front, exposed edge of the floor
slab. See item III, below.
- Exposed edges of
existing concrete floor slabs. As mentioned above, these slab corners
show several instances where damage is evident or repairs have been
made to try to correct the damaged areas. It appears that the floor
slabs are in reasonably good condition and with proper attention given
to repair and maintenance, they should continue to stay in good,
serviceable condition. Our recommendation would be to remove all loose
and/or damaged concrete, clean all exposed surfaces, with clean tools
and brushes free of all contaminants. Prepare all exposed surfaces with
concrete primer, form and pour with expanding, hydraulic cement, and
finish with a weather resistant finish material that matches the finish
on the adjacent, existing concrete area.
- Rear,
cantilevered balcony decks. Visual inspection of three (of sixteen (16)
total) decks revealed that they were probably in good serviceable
condition. The reasons preventing a more definite opinion on this item,
are as follows: on this inspection tour, we were only able to inspect
one (1) deck from the top side, and two (2) other decks from the
underside. We recommend that each deck, at the very least, receive a
visual inspection by a registered structural engineer. Other factors
preventing us from forming more definite opinions on the condition of
these decks are the fact that several have installed tile or other
finish materials over the deck; thus preventing a look at visual clues
as to any deterioration or damage. On the underside, wood facia and
short soffit trim boards prevent a good look at possible deterioration
or damage. With all of this said, from the limited number of decks
actually inspected, they appear to be in stable condition. We would
strongly suggest, that in follow up to the recommended inspection, that
these steps be taken to protect and/or prevent damage. Clean and vacuum
any cracks that are visible to the inspector. Use a good quality
expanding, hydraulic cement, to fill the opening(s). Take the same
steps as outlined above (items #II and #III), if sections of concrete
have fallen away, and exposed steel reinforcement below. If there are
any questions in regard to the units that have finished floor surfaces
already installed on their deck; further inspection and testing could
only be done if the existing finish materials are removed. Once the
tile, carpet or other material is removed, it is recommended that
concrete strength is tested by standard ?Swiss Hammer? methods.
- Existing,
flat, built-up roof with large aggregate ballast. Because of the age of
this roof, many would recommend that you do a complete replacement.
Given the history of no apparent serious leak problems and the fact
that some regular, scheduled maintenance would probably extend this
roof for several years, we would recommend the following: start with a
thorough but careful cleaning and removal of all organic debris,
especially in collection areas around roof drains and scuppers.
Schedule this procedure to be done every three months. While this is
being done a licensed roofing (commercial) contractor should make a
visual inspection for preventative maintenance and repair. Make the
suggested repairs with the idea that it will be the best insurance
investment in this roof. If a roof replacement fund has not been
started, we would recommend that the owners start that program, as
well. Remember the flat roof guarantee, ?they will leak?. The steps
outlined above will prevent some of these leaks and reduce the severity
of others.
- Existing, wood shake shingle accent
panels. The appearance of these upper level ?shingles? is not good.
Upon closer inspection, we were able to determine that they are in
better overall condition than what they appear. There are several
instances where the exposed corners and/or edges have been damaged or
loosened. I believe that the damaged shingle panels can be replaced
with matching, panelized shake shingles, and that with these repairs,
these shingles will give years of good service. As far as the
appearance, I would suggest that the cedar cleaning agents NOT be used.
They are too harsh and may well damage the adhesive in this laminated
product. Rather, I would suggest that the shingle panels be soft washed
with an organic spore killing agent, and then coated with two (2) coats
of solid stain in a complimentary color (to the stucco and trim
colors). Do NOT power wash these shingles!
Final Recommendations
It
is our recommendation that because of the numerous safety factors
concerning the railings and handrails, that the existing railings
should be removed, and new railings and hand rails should be installed.
We would make the following recommendations: first, the new railings
should be mounted between columns and sound wall structure or other
concrete columns. The new railings should not be face mounted to the
edges of the floor slabs. The new railings should be designed with a
raised shoe, to permit surface run off of wind driven rain. These new
railings shall be raised to 42? above the adjacent, finished floor
elevation. The entire railing and hand rail system should be designed
by a registered engineer, to comply with current safety standards,
while enhancing the visual appearance of the overall property.
