2. Wetting: Wet brick so the absorption rate does not exceed ASTM C -67 standards. When the air
temperature is very hot and dry, or moderately hot and windy, wet the brick several times to insure
all the bricks have been wetted. This shall be done several hours ahead of usage so the brick has no
surface water, but the absorption rate has been reduced to prevent sucking the water out of the
mortar mixture.
3. Face units in vertical walls shall be laid in a standard running bond, except as specifically noted
on the drawings. Window sills shall be laid rowlock, or as called for on the drawings.
4. Joints: Shall be nominal 3/8" wide vertically and horizontally. Joints on all exposed masonry
shall be standard tooled and compressed concave. When mortar is thumbprint hard, use a round
jointer /tooler to produce joint. Mortar shall be hard and firmly compressed.
5. Joining: Where fresh masonry joins partially set masonry, remove loose bricks and mortar, clean
and lightly wet contact surfaces. Stop horizontal runs by racking back one half (1/2) unit in each
course. Toothing shall not be permitted.
6. Thru -Wall Base Flashing: Install thru -wall flashing behind the sheathing as shown on the
drawings and extend up 8" between the back face of the stud and the back face of the sheathing.
Extend flashing atop bottom ledge and trim flush to conceal.
7. Weepholes: Weepholes rope wicks, trimmed flush at 24" o.c. Rope wicks shall be untreated
cotton or fiberglass rope with a diameter of not less than 3/16" nor greater than 1/4" diameter.
Wicks shall extend 8" vertically in the cavity. Hold in place with duct tape. Keep cavity between
sheathing and brick free of mortar droppings.
8. Installation: Install brick plumb and true to lines in all directions. Discard all bricks that are not '
within tolerance as to size or shape, are chipped, or off color. Install brick with finished face out.
Do not pound or hammer to fit units after they are in position. When adjustment must be made after
mortar has begun to set, remove mortar and replace it with fresh. Remove mortar dropping on the
face of all exposed bricks as they occur. Do not allow mortar to harden on the finally exposed
portions of the work.
9. Reinforcing: Ties shall be equal to National Wire #700 Corrugated Lateral Support Anchors, 12
gauge, 1.25" wide, with pre - formed attachment holes, hot dipped galvanized steel, length as
required to provide proper attachment to the wall, and a 5/8" weather coverage. Spacing shall be
16" max. o.c. horizontally, and 16" o.c. vertically commencing 8" above the start of the first course.
10. Cleaning: Brick shall be cleaned upon completion of all brick work. Masonry cement shall be
cleaned from windows, doors, concrete and other materials. Point up exposed masonry voids,
cracks, and surface imperfections. Use water and a stiff wire brush to clean off excess mortar. Do
no strike off surface mortar with metallic objects as this may spall off the finished face of the brick
causing it to be replaced. Masonry cleaning products to be applied according to manufacturer's
directions. Any solution used shall be acid and efflorescent free, similar to Sure -Klean as
manufactured by ProSoCo, Inc. Wash off all traces of cleaning agent when complete and flood
surface to remove all contaminates.

Backfill for the pipe base and within the pipe zone should be placed in maximum 12 -inch-
thick lifts and compacted to not less than 90 percent of the maximum dry density, as
determined by ASTM D 1557 or as recommended by the pipe manufacturer. Backfill above
the pipe zone should be placed in maximum 12- inch -thick lifts and compacted to not less
' than 92 percent of the maximum dry density, as determined by ASTM D 1557. Trench
backfill located within 2 feet of finish subgrade elevation should be placed in maximum
12 -inch -thick lifts and compacted to not less than 95 percent of the maximum dry density,
' as determined by ASTM D 1557.
RETAINING STRUCTURES
For walls not restrained from rotation, we recommend using an equivalent fluid pressure of
33 pcf for design. We recommend using an equivalent fluid pressure of 55 pcf for design of
walls restrained from rotation. When computing resistance to lateral loads, we recommend
' using a base friction coefficient of 0.30. Footings for the retaining walls should be designed
for a maximum bearing pressure of 2,500 psf, in accordance with the recommendations
given for shallow spread footings.
Wall drains should include perforated drainpipe wrapped in a non -woven geotextile filter
installed behind the walls at the base. Walls should be backfilled with imported granular
material, as described in the "Structural Fill" section of this report.
The above design recommendations are based on the assumptions that: (1) the walls
consist of conventional cantilevered retaining walls or embedded building walls, (2) the
:�. walls are less than 10 feet in height, (3) the backfill is level and drained and consists of
. ` imported granular materials, and (4) no surcharges are imposed behind the wall.
., Reevaluation of our recommendations will be required if the retaining wall design criteria for
the project vary from these assumptions.
' PERMANENT SLOPES
Permanent slopes should not exceed 2H:1V (horizontal to vertical). Adjacent on -site and
' off -site structure and surfacing should be located at least 5 feet from the top of slopes.
Footings constructed within slopes should have a minimum of 5 feet between the face of
the slope and the outer edge of the footing.
Groundwater conditions may create seepage from cut slopes at the site. Provisions should
be made to direct seepage away from the face and toe of slopes where it occurs.
' DRAINAGE CONSIDERATIONS
We recommend that subsurface drains be connected to a tightline leading to the storm
' drain. Pavement surfaces and open space areas should be sloped such that the surface
water runoff is collected and routed to suitable discharge points. We recommend that the
ground and paved surfaces adjacent to the building be sloped to drain away from the
' building. We also recommend using perimeter foundation drains in areas that will be cut
below existing grades.

No. 200 Sieve. The percentage of fines can be increased to 12 percent of the material
passing the U.S. Standard No. 200 Sieve if placed during dry weather. Imported granular
material should be moisture conditioned to the approximate optimum moisture content for
' compaction, placed in 12- inch -thick lifts, and compacted to not less than 95 percent of
maximum dry density as determined by ASTM D 1557.
CEMENT AMENDMENT
As an alternative to the use of imported granular material for structural fill, working blankets
and haul roads, an experienced contractor may be able to amend the on -site soils with
portland cement to obtain suitable support for fill operations and /or support of construction
equipment. Based on the moisture contents, soil type, and processing speed, cement
amendment would be more suitable at this site than lime amendment.
' Successful use of soil amendment depends on use of correct techniques and equipment,
soil moisture content, and the amount of portland cement added to the soil.
' Recommended cement percentages are based on soil moisture contents at the time of
placing the structural fill. Based on our tests and experience, about 4 percent by dry
weight of soil can generally be used when the soil moisture content does not exceed
' approximately 25 percent. If the soil moisture content is in the range of 25 to 35 percent,
we recommend 5 to 6 percent cement by weight of dry soil. It is difficult to accurately
predict field performance due to the variability in soil response to portland cement
amendment. The percentage of cement may need to be adjusted based on field
observations and performance. For preliminary design purposes, we recommend a
minimum of 5 percent cement and a treatment depth of 12 inches. At this site, 5 percent
' cement would correspond to about 4.5 pounds of cement per square foot, for a 12 -inch
treatment depth.
' SHALLOW FOUNDATIONS
We recommend that spread footings have a minimum width of 24 inches, with the base of
the footings founded at least 18 inches below the lowest adjacent grade. Continuous wall
' footings should have a minimum width of 18 inches, and be founded a minimum of 18
inches below the lowest adjacent grade.
' Bearing Pressure and Settlement
Footings with the preceding loads and founded as recommended should be proportioned
' for a maximum allowable soil bearing pressure of 2,500 psf. This bearing pressure is a net
bearing pressure and applies to the total of dead and long -term live loads and may be
increased by one -third when considering earthquake or wind loads. The weight of the
footing and overlying backfill can be ignored in calculating footing loads.
For a 2,500 psf design bearing pressure, total settlement of footings is anticipated to be
' less than about 1 -inch for the building loads discussed above. Differential settlements
should not exceed '/2 -inch.

SITE PREPARATION AND EROSION CONTROL
The existing topsoil should be stripped and removed from the site in all proposed building
and pavement areas and for a 5 -foot margin around such areas. Based on our
explorations, the depth of stripping will be approximately 6 inches, although greater
stripping depths may be required to remove localized zones of loose or organic soil. The
' actual stripping depth should be based on field observations at the time of construction.
Stripped material should be transported off -site for disposal or used in landscaped areas.
After stripping and required site cutting have been completed, we recommend proofrolling
the subgrade with a fully - loaded dump truck or similar -size, rubber -tire construction
equipment to identify areas of excessive yielding. A member of our geotechnical staff, who
will evaluate the subgrade, should observe the proofrolling. If areas of excessive yielding
are identified, the material should be excavated and replaced with structural fill. Areas that
' appear to be too wet and soft to support proofrolling equipment should be prepared in
accordance with the recommendations for wet weather construction.
' Silt fences, hay bales, buffer zones of natural growth, sedimentation ponds, and granular
haul roads should be used as required to reduce sediment transport during construction to
acceptable levels. Measures to reduce erosion should be implemented in accordance with
' Oregon Administrative Rules 340 -41 -006 and 340 -41 -455 and Washington County and City
of Hillsboro regulations regarding erosion control.
' STRUCTURAL FILL
On -site Materials
The site silts are sensitive to small changes in moisture content and highly susceptible to
' disturbance when wet. If construction is planned for the wet season then careful
consideration of the construction methods and schedule should be made to reduce
overexcavation of disturbed site soils, and the project budget should reflect the
' recommendations for wet weather construction contained in this report.
Laboratory testing indicates that the moisture content of the on -site materials is greater
' than the anticipated optimum moisture content required for satisfactory compaction.
Therefore, moisture - conditioning will be required to achieve adequate compaction. We
recommend using imported granular material for structural fill if the on -site material cannot
be properly moisture - conditioned. As an alternative, use of the on -site silt for structural fill
may be acceptable if it is properly amended with portland cement or lime.
' When used as structural fill, the on -site silty material should be placed in lifts with a
maximum uncompacted thickness of no less than 8 inches. The silt should be compacted
to not less than 92 percent of the maximum dry density, as determined by American
Society for Testing and Materials (ASTM) D 1557.
' Imported Granular Material
If imported granular material is used as structural fill, this material should consist of pit or
quarry run rock, crushed rock, or crushed gravel and sand that is fairly well - graded
' between coarse and fine, contains no organic matter or other deleterious materials, has a
