REVISION OF SECTION 104
LANE RENTAL FEE
Section 104 of the Standard Specifications is hereby revised for this project as follows:
Subsection 104.04 shall include the following:
(a) Lane Rental Fee. The Contractor shall pay a daily lane rental fee for lane closures on Timberline Road and
Prospect Road during construction.
The Contractor will be granted the following lane rental allowances:
120 calendar days of multi-day closures on Timberline Road
50 calendar days of multi-day closure on Prospect Road
120 calendar days of single day (8:30 am to 3:30 pm) daytime closure on the entire project
From these allowed lane-days, no deduction will be made from monies due the Contractor. Lane rental fees
for all lane-days in excess of the listed allowances above will be deducted from any monies due the
Contractor for work performed. The deduction will be based on the applicable rate for any and all closures,
whether work is performed or not. This deduction will be reflected in each progress payment. This
deduction is not a penalty, but is a rental fee based upon road user costs to occupy individual lanes on
Prospect Road and Timberline Road.
The Engineer may determine that the lane rental fee will not be charged for lane closures for the following
reasons: additional work not covered in the scope of the project; acts of god, acts of the public enemy, fires,
floods, area wide strikes, freight embargos, and delays not caused by the Contractor’s fault or negligence. In
the case of unusually severe weather, a lane rental fee will not be charged for each weather day after the
second consecutive weather day.
City of Fort Collins Light and Power and City Traffic Department have work that the contractor will need to
coordinate within the existing lane rental requirements above. See Utilities, page 95 of the Project Special
Provisions for more information. In the case that City Light and Power or City Traffic Dept. needs a lane
closure and the contractor is not also performing work or scheduled to perform work within that closure, a
Lane Rental Day will not be charged.
The lane-day rental fee for closures on Timberline and Prospect shall be $ 1,500.00 per lane-day.
A lane-day is measured as any day that a portion of a thru lane or signalized left turn lane is closed to traffic
on any arterial road.
.
The following will not be measured as lane-days:
Any day that a right turn lane is closed but a right turn is permitted from an existing thru-lane.
Any day that an opposable left turn lane is closed to traffic on an arterial road.
A single weekend allowance will be made only for asphalt top lift paving. During this single
weekend, the City will not impose lane rental fees for lane closures on Timberline/Prospect. The
weekend will start at 7:00 PM on a Friday and end at 6:00 AM on the following Monday morning.
See traffic Control Specifications for more details on weekend closure restrictions.
For approved daytime lane closures, a lane-day will be measured as any potion of time between the hours of
8:30 AM to 3:30 PM. If work extends beyond those approved working hours, an Unapproved Lane Rental
Fee will be charged per section (b).
For approved multi-day lane closure, the lane-day will be measured as a 24 hour period from 12:00 AM to
11:59 PM for each calendar day that the closure is approved and implemented.
February 19, 2016
12
Only 1 lane rental day will be charged for any single lane, regardless of the number of lane closures in that
lane. For example, if SB outside Timberline lane is multi-day closed south of Prospect Road and also the SB
outside Timberline lane is multi-day (or single day) closed north of Prospect Road, only 1 multi-day lane
rental will be charged for that day’s outside Timberline Road lane closure.
For approved night time work during off-peak hours, a lane rental fee will not be charged.
A lane is considered closed when the number of available lanes is reduced from the number available prior to
the work.
Lane closures shall be documented in the Traffic Control Supervisor’s (TCS’s) diary each day that a lane
closure is in use. The diary shall be signed by the TCS and the Contractor’s representative. A copy of the
day’s diary shall be given to the Engineer at the end of each work day on which a lane closure is used.
(b) Unapproved Lane Rental Fee:
The Contractor will be charged a lane rental fee for any work that is performed outside of the approved
daytime hours that are permitted by the City Traffic Dept. on the approved MHT. The lane rental fee will be
measured as an hourly rate and will be rounded up to the nearest whole hour in excess of the permitted lane
closure time.
The Unapproved Lane Rental Fee for single daytime closures on Timberline Road and Prospect Road shall
be $ 500.00 per lane-hour.
The Unapproved Lane Rental Fee will be measured and applied separately to each thru lane or signalized left
turn lane that is impacted by an unapproved lane closure.
Approved daytime lane closure MHTs cannot be field modified into multiday lane closures to avoid the
Unapproved Lane Rental Fee.
The Unapproved Lane Rental Fee does not constitute an authorization to do work without an approved traffic
control plan.

Section 108 of the Standard Specifications is hereby revised for this project as follows:
Subsection 108.07 shall include the following:
It is anticipated that construction for this project will begin in Spring 2016.
Prior to the commencement of work, the Contractor shall submit to the Project Manager, for approval, a schedule
showing the time of commencement and proposed progress of the work. In this schedule, the Contractor shall
anticipate and account for adverse weather conditions, utility coordination and time restrictions for lane closures.
If the Contractor falls behind the approved schedule, then all reasonable efforts shall be implemented to
accelerate the schedule and complete the work within the contract time. The Contractor shall furnish additional
resources (e.g. equipment, manpower, etc.) and implement other strategies to expedite the construction, at no
additional cost to the project.
The Substantial Completion for the Work shall occur within 135 calendar days following issuance of the Notice to
Proceed. Substantial Completion will require the completion of all hot mix asphalt; curb and gutter; pedestrian
ramps and sidewalks.
The Final Completion for the work shall occur within 40 calendar days following the issuance of the
Notice of Substantial Completion” letter. Final Completion will require the completion of all landscape walls,
boulder placement, double median curbs, pedestrian bridge, decorative railings, topsoil, irrigation, landscape
plantings, punchlist items, and demobilization.
When the Contractor considers the entire work ready for its intended use, he shall notify the Project Manager in
writing and request that the Project Manager issue the Notice of Final Completion. Within a reasonable amount of
time, the City, , and other stakeholders shall make an inspection of the work to determine the status of
completion. If the work is complete, the Project Manager will issue the Notice of Final Completion and attach a
―punch listǁ of items to be completed or corrected prior to final payment.
Failure by the Contractor to complete the work on time will result in daily charges for liquidated damages. Failure
to meet Substantial Completion will incur liquidated damages of $3,300 per calendar day assessed per Section
108.09 of the Colorado Department of Transportation Standard Specifications for Road and Bridge Construction,
latest edition.
Failure by the Contractor to complete the work on time will result in daily charges for liquidated damages. Failure
to meet Final Completion will incur liquidated damages of $1,300 per calendar day assessed per Section 108.09 of
the Colorado Department of Transportation Standard Specifications for Road and Bridge Construction, latest
edition
Contract time may be adjusted only through Change Order. Any requests for extension of time due to conditions
outside the Contractor’s control shall be made in writing to the Project Manager within 7 calendar days of the
cause of delay. The Project Manager shall respond in writing within 14 calendar days of receiving the
Contractor’s request.
Contractor will need to coordinate with the City’s Parks Department for the Grain Silo Removal by June 10, 2016.
Modifications to Time of Completion in the Approved Schedule
The date of beginning and the time for completion of the work are essential conditions of the Contract
Documents and the work embraced shall be commenced on a date specified in the Notice to Proceed.
The Contractor will proceed with the work at such rate of progress to ensure full completion within the
contract time. It is expressly understood and agreed, by and between the Contractor and the Owner that
the contract time for the completion of the work described herein is a reasonable time, taking into
consideration the climatic and other factors prevailing in the locality of the work.
Every effort shall be made by the Contractor to complete the project within the "Contract Time" shown in
February 19, 2016
19
the proposal. The "Contract Time" anticipates "Normal" weather and climate conditions in and around the
vicinity of the Project site during the times of year that the construction will be carried out. Extensions of
time based upon weather conditions shall be granted only if the Contractor demonstrates clearly that such
conditions were "unusually severe," would not have been reasonably anticipated, and that such
conditions adversely affected the Contractor’s work and thus required additional time to complete the
work.
The following specifies the procedure for the determination of time extensions for unusually severe
weather. The listing below defines the anticipated number of calendar days lost to adverse weather for
each month and is based upon National Oceanic and Atmospheric Administration (NOAA) or similar data
for the geographic location of the project.
Monthly Anticipated Calendar Days Lost to Adverse Weather Conditions
JAN FEB MAR APR MAY JUN JUL AUG SEP OCT NOV DEC
(7) (4) (4) (4) (6) (3) (4) (2) (3) (3) (2) (5)
The above schedule of anticipated adverse weather will constitute the base line for monthly (or portion thereof)
weather time evaluations. Upon acknowledgment of the Notice to Proceed and continuing throughout the
contract on a monthly basis, actual adverse weather days and the impact of adverse weather days that delay the
work will be recorded on a day-to-day basis. It is assumed that the work will be carried out Mondays through
Fridays (holidays excepted) unless an approved construction schedule or written authorization from the Owner
indicates otherwise. The number of days of delayed work due to adverse weather or the impact thereof will then
be compared to the monthly adverse weather schedule above.
An actual adverse weather day must prevent work for 50 percent or more of the Contractor’s workday, delay work
critical to the timely completion of the project, and be documented by the Contractor. The City Representative
observing the construction shall determine on a daily basis whether or not work can proceed or if work is delayed
due to adverse weather or the effects thereof. The Contractor shall notify the Engineer in writing of any
disagreement as to whether or not work can proceed on a given date, within 2 calendar days of that date. The
Owner will use the above written notification in determining the number of working days for which work was
delayed during each month.
At the end of each month, if the number of working days for which work was delayed due to adverse weather
exceeds that shown in the above schedule, a Change Order will be executed which increases the Contract Time.
The number of work days delayed due to adverse weather or the impact thereof will then be converted to
Calendar Days based on the contract completion day and date. This conversion assumes a 5-day work week,
Mondays through Fridays, holidays excepted; should the Contractor have authorization to work weekends and/or
holidays, then the method of conversion of workdays to calendar days would take this into consideration. The
contract time period will then be increased by the number of calendar days calculated above and a new contract
completion day and date will be set.
The Contractor’s schedule must reflect the above-anticipated adverse weather delays on all weather-dependent
activities. While extensions of time shall be granted for "unusually severe" weather or climate conditions, the
Owner shall make no monetary compensation for any costs to the Contractor arising out of such delays. The
Contractor shall comply with the portions of the Contract Documents relating to his project schedule and
amendments thereto which result from the "unusually severe" weather condition.
Breakdowns in equipment or lack of performance by the Contractor will not be considered justification for an
extension of time. Liquidated damages will be assessed as delineated elsewhere.
The Contractor shall not be charged with liquidated damages or any excess cost when the delay in completion of
the work is due to the following, and the Contractor has promptly given written notice of such delay to the Owner
or Engineer.
1. To any preference, priority, or allocation order duly issued by the Owner.
2. To unforeseeable causes beyond the control and without the fault or negligence of the Contractor,
February 19, 2016
20
including but not restricted to, acts of God, or of the public enemy, acts of the Owner, acts of another Contractor
in the performance of a contract with the Owner, fires, floods, epidemics, quarantine restrictions, strikes, freight
embargoes, and abnormal and unforeseeable weather as provided above; and
3. To any delays of Subcontractors occasioned by any of the causes specified in paragraphs 1 and 2,
above.

strategies/R4_Lane_Closure_Report.pdf/view
Unless otherwise approved by the Engineer, the Contractor’s equipment shall follow normal and legal traffic
movements. The Contractor’s ingress and egress of the work area shall be accomplished with as little disruption
to traffic as possible. Traffic control devices shall be removed by picking up the devices in a reverse sequence to
that used for installation. This may require moving backwards through the work zone. When located behind
barrier or at other locations shown on approved traffic control plans, equipment may operate in a direction
opposite to adjacent traffic.
No separate payment will be made for removal of existing pavement markings necessary for temporary lanes
shifts or other conditions proposed in the Contractor’s Method of Handling Traffic. All pavement markings,
interim and permanent, shall be installed in accordance with Section 627, the approved plans and the Manual on
Uniform Traffic Control Devices. Removal of existing pavement markings, if required, shall be considered
incidental to Pavement Marking Paint (Waterborne) (Temporary) and other related pay items. ―Blacking outǁ
existing pavement markings will not be allowed.
CDOT may have entered into operating agreements with one or more law enforcement organizations for
cooperative activities. Under such agreements, at the sole discretion of CDOT, law enforcement personnel may
enter the work zone for enforcement purposes and may participate in the Contractor’s traffic control activities.
The responsibility under the Contract for all traffic control resides with the Contractor and any such participation
by law enforcement personnel in Contractor traffic control activities will be referenced in either the Special
Provisions or General Notes of the plans depending on whether the Contractor is to contract with Colorado State
Patrol for uniformed traffic control. Nothing in this Contract is intended to create an entitlement, on the part of the
Contractor, to the services or participation of the law enforcement organization.

ject. The scope was described in our Service Agreement (FC-12-0365R1, dated
April 24, 2015). A supplemental report for the Subgrade Investigation and Pave-
ment Design for the widening of Timberline Road will be provided separately.
The report was prepared from data developed during field exploration, la-
boratory testing, engineering analysis and experience with similar conditions.
The report includes a description of subsurface conditions found in our explora-
tory borings and discussions of site development as influenced by geotechnical
considerations. Our opinions and recommendations regarding design criteria
and construction details for site development, foundations, slabs-on-grade, lat-
eral earth loads and drainage are provided. If the proposed construction
changes, we should be requested to review our recommendations. Our conclu-
sions are summarized in the following paragraphs.
SUMMARY OF CONCLUSIONS
1. Soils encountered in our borings consisted 14 to 20 feet of sandy
clay and clayey sand over sand and gravel. Claystone bedrock was
encountered at 20 and 31 feet to the depths explored.
2. Groundwater was encountered in our borings at depths of 11 and
15 feet during drilling and 9 and 12 feet several days after drilling.
Existing groundwater levels along with water levels in the Spring
Creek will likely affect the proposed construction at this site.
Groundwater levels are expected to fluctuate seasonally.
3. We believe the proposed pedestrian bridge can be constructed on
spread footing foundation placed on natural, undisturbed soil and/or
properly compacted fill or drilled pier foundation bottomed into bed-
rock. Foundation design and construction recommendations are
presented in this report.

SITE CONDITIONS AND PROPOSED CONSTRUCTION
The proposed pedestrian bridge will span Spring Creek on the west side
of Timberline Road near the intersection of Timberline Road and Prospect Road.
Spring Creek runs west to east and was approximately ½-foot deep at the time of
drilling. The land slopes steeply from the test hole locations toward the creek
and was covered in grass, weeds and trees.
INVESTIGATION
Subsurface conditions were investigated by drilling two borings to depths
of approximately 35 feet. The approximate locations of the borings are shown on
Figure 1. Our field representative observed drilling, logged the soils found in the
borings and obtained samples. Sampling was performed by driving a 2.5-inch
O.D. modified California sampler with blows of a 140-pound hammer falling 30
inches. This method is similar to the standard penetration test, and is typical for
local practice. Groundwater measurements were taken during drilling and sev-
eral days afterward. Summary logs of the borings, including results of field pene-
tration resistance tests, are presented on Figure 2.
Samples obtained during drilling were returned to our laboratory and visu-
ally examined by the geotechnical engineer for this project. Laboratory analyses
included moisture content, dry density, swell-consolidation, particle-size analysis,
and water-soluble sulfate tests. Results of laboratory tests are presented on Fig-
ures 3 and 4 and summarized in Table I.

ter drilling. Existing groundwater levels along with water levels within Spring

Creek will likely affect the proposed construction at this site and might require de-
watering. Groundwater levels are expected to fluctuate seasonally.
Samples of the sands and gravels tested in the laboratory indicated fines
contents (percent passing No. 200 sieve) of 6 to 38 percent. The clays in our bor-
ings exhibited minor compression (0.1 percent) to low swelling potential (0.9 per-
cent). The claystone bedrock tested in the laboratory indicated fines content (per-
cent passing No. 200 sieve) of 94 percent. Further description of the subsurface
conditions is presented on our boring logs and in our laboratory testing.
SEISMICITY
This area, like most of central Colorado, is subject to a low degree of seis-
mic risk. As in most areas of recognized low seismicity, the record of the past
earthquake activity in Colorado is incomplete. According to the 2012 Interna-
tional Building Code and the subsurface conditions encountered in our borings,
this site probably classifies as a Site Class D. Only minor damage to relatively
new, properly designed and built buildings would be expected. Wind loads, not
seismic considerations, typically govern dynamic structural design in this area.
SITE DEVELOPMENT
Fill Placement
The existing onsite soils are suitable for re-use as fill material provided de-
bris or deleterious organic materials are removed. If import material is used, it
should be tested and approved as acceptable fill by CTL|Thompson. In general,
import fill should meet or exceed the engineering qualities of the onsite soils. Ar-
eas to receive fill should be scarified, moisture-conditioned and compacted to at
least 95 percent of standard Proctor maximum dry density (ASTM D698,
AASHTO T99). Sand soils used as fill should be moistened to within 2 percent of
optimum moisture content. Clay soils should be moistened between optimum
INTERWEST CONSTULTING GROUP
TIMBERLINE ROAD CORRIDOR IMPROVEMENT
CTLT PROJECT NO. FC06181-125
4
and 3 percent above optimum moisture content. The fill should be moisture-con-
ditioned, placed in thin, loose lifts (8 inches or less) and compacted as described
above. We should observe placement and compaction of fill during construction.
Fill placement and compaction should not be conducted when the fill material is
frozen.
Water and sewer lines are often constructed beneath areas where im-
provements are planned. Compaction of trench backfill can have a significant ef-
fect on the life and serviceability overlying structures. We recommend trench
backfill be moisture conditioned and compacted as described in the Fill Place-
ment section of this report. Placement and compaction of fill and backfill should
be observed and tested by a representative of our firm during construction.
Excavations
The materials found in our borings can be excavated using conventional
heavy-duty excavation equipment. Excavations should be sloped or shored to
meet local, State and Federal safety regulations. Excavation slopes specified by
OSHA are dependent upon types of soil and groundwater conditions encoun-
tered. The contractor’s “competent person” should identify the soils and/or rock
encountered in the excavation and refer to OSHA standards to determine appro-
priate slopes. Stockpiles of soils, rock, equipment, or other items should not be
placed within a horizontal distance equal to one-half the excavation depth, from
the edge of excavation. Excavations deeper than 20 feet should be braced or a
professional engineer should design the slopes.
Bracing
Bracing or “trench box” construction may be necessary in order to limit the
width of excavations and reduce the amount of surface disturbance. Bracing
systems include driven sheet piling, soldier piles and lagging, and others. Lateral
INTERWEST CONSTULTING GROUP
TIMBERLINE ROAD CORRIDOR IMPROVEMENT
CTLT PROJECT NO. FC06181-125

loading of bracing depends on the depth of excavation, slope of excavation
above the bracing, soil stockpiles and other surface loads, hydrostatic pressures,
and allowable movement.
For bracing allowed to move enough to mobilize the strength of the soils
with associated settlement and cracking of the ground surface, “active” earth
pressure conditions are appropriate for design. If movement is not tolerable, “at
rest” earth pressures are appropriate. Recommendations for lateral load criteria
are provided in the LATERAL EARTH PRESSURES section. The OSHA con-
struction standards provide recommendations for timber bracing. We are also
available to assist further with bracing design if desired.
Dewatering
Groundwater was encountered in both of our borings at depths of 9 and
12 feet. Groundwater depths can vary with seasons, irrigation usage, water lev-
els in nearby drainages including Spring Creek and, depending on the time of
construction, could be higher than measured in our borings. Based on the
planned depth of excavations, we anticipate groundwater will be encountered in
excavations for the bridge abutments.
Excavations within about 3 feet of the groundwater levels should consider
temporary dewatering prior to and/or during construction. Dewatering can be ac-
complished using a series of trenches, sumps and granular materials from which
water can be pumped, or by a system of well points. The sumps should be sev-
eral feet below the bottom of the excavations to pump water down through the
soil rather than up through the bottom of the excavation. Pumping water up
through the base of the excavation may result in “quick conditions” and destabili-
zation of the base of the excavation. The ground surface surrounding the exca-
vation should be sloped to direct surface runoff away from the excavation.
INTERWEST CONSTULTING GROUP
TIMBERLINE ROAD CORRIDOR IMPROVEMENT
CTLT PROJECT NO. FC06181-125

For excavations planned several feet below the groundwater level, a se-
ries of well points may be needed to dewater the excavation effectively. The
contractor should anticipate extensive dewatering and caving soils in excavations
below the water table. The design of a dewatering system was not included in
our scope of work. We can assist with a dewatering design, if requested.
FOUNDATIONS
Spread footing foundations or drilled piers are considered appropriate for
the conditions encountered. Drilled piers may be needed due to scouring and
higher loads. Wing wall or other retaining walls that are integral with the bridge
abutment should be founded on the same foundation type as the abutment. De-
sign criteria for spread footing and drilled pier foundations developed from analy-
sis of field and laboratory data and our experience are presented below.
Spread Footings
1. Footings should be constructed on undisturbed natural soils or
properly compacted fill (see the Fill Placement section of this re-
port). Where soil is loosened during excavation, it should be re-
moved and replaced with on-site soils and compacted following the
criteria in the Fill Placement section of this report.
2. Footings constructed on the natural soils and/or engineered fill can
be designed for a net allowable soil pressure of 3,000 psf. The soil
pressure can be increased 33 percent for transient loads such as
wind or seismic loads.
3. Footings should have a minimum width of at least 16 inches. Foun-
dations for isolated columns should have minimum dimensions of
18 inches by 18 inches. Larger sizes may be required depending
on loads and the structural system used.
4. The soils beneath footing pads can be assigned an ultimate coeffi-
cient of friction of 0.4 to resist lateral loads. The ability of grade
beam or footing backfill to resist lateral loads can be calculated us-
ing a passive equivalent fluid pressure of 300 pcf. This assumes
the backfill is densely compacted and will not be removed. Backfill
INTERWEST CONSTULTING GROUP
TIMBERLINE ROAD CORRIDOR IMPROVEMENT

should be placed and compacted to the criteria in the Fill Place-
ment section of this report.
5. Exterior footings should be protected from frost action. We believe
30 inches of frost cover is appropriate for this site.
6. We should observe completed footing excavations to confirm that
the subsurface conditions are similar to those found in our borings.
Drilled Piers Bottomed in Bedrock
1. Piers should be designed for a maximum allowable end pressure of
40,000 psf and an allowable skin friction of 4,000 psf for the portion
of pier in bedrock. Skin friction should be neglected for the upper 3
feet of pier below grade beams. Pier end pressure can be in-
creased 30 percent for short duration live loads such as wind loads.
2. Piers should penetrate at least 5 feet into the comparatively fresh
claystone bedrock.
3. There should be a 4-inch (or thicker) continuous void beneath all
grade beams and foundation walls, between piers, to concentrate
the dead load of the structure onto the piers.
4. Foundation walls and grade beams should be well reinforced. A
qualified structural engineer should design the reinforcement. Lat-
eral earth pressures and the effects of large openings within base-
ment walls should be considered.
5. Pier borings should be drilled to a plumb tolerance of 1.5 percent
relative to the pier length.
6. Groundwater was encountered during this investigation. If more
than 3 inches of ground water collects in the bottom of the holes
during pier installation, temporary casing, tremie equipment, and/or
pumping will likely be necessary for proper cleaning, dewatering,
and concrete placement.
7. Concrete placed by the free fall method should have a slump be-
tween 5 inches and 7 inches. Concrete placed by pump, tremie or
when temporarily cased should have a slump between 6 inches
and 8 inches.
INTERWEST CONSTULTING GROUP
TIMBERLINE ROAD CORRIDOR IMPROVEMENT

8. Formation of “mushrooms” or enlargements at the top of piers
should be avoided during pier drilling and subsequent construction
operations.
9. We should observe installation of drilled piers to confirm the sub-
surface conditions are those we anticipated from our borings.
Laterally Loaded Piers
Several methods are available to analyze laterally loaded piers. With a
pier length to diameter ratio of 7 or greater, we believe the method of analysis
developed by Matlock and Reese is most appropriate. The method is an iterative
procedure using applied loading and soil profile to develop deflection and mo-
ment versus depth curves. The computer programs LPILE and COM624 were
developed to perform this procedure. Suggested criteria for LPILE analysis are
presented in the following table.

LATERAL EARTH PRESSURES
The lateral loads acting on walls are dependent on the height and type of
wall, backfill configuration and backfill type. Table B below provides the necessary
equivalent fluid pressure values for the backfill soils anticipated at this site. The
pressures given do not include allowances for surcharge loads such as sloping
backfill, vehicle traffic, or excessive hydrostatic pressure.

Loading Condition
Equivalent Hydrostatic
Fluid Pressure
At-Rest (γo) pcf 40
Active (γA) pcf 55
Passive (γp) pcf 300
Horizontal Friction Coefficient 0.4
For walls that are restrained from rotation, they should be designed to resist
the “at rest” earth pressure. Resistance to lateral loads can be provided by friction
between concrete and soil and/or by “passive” earth pressure. Passive earth pres-
sure should be ignored for the top one foot of soils against the structure since it
can be easily removed with time. The proper application of these loading condi-
tions is the responsibility of the wall designer.
The hydrostatic pressure can be reduced by providing a drain and weep
holes behind the walls. The drain should be reasonably well-graded sands and
gravels with a maximum of 5 percent passing the No. 200 sieve and a maximum
particle size of 3 inches that is at least 12 inches wide and placed against the back
of a wall. The top 2 feet of backfill above the drain should be compacted clays.
Weep holes should be 4 inches in diameter, spaced 10 feet center-to-center at the
bottom of an abutment or wall. At least two weep holes should be provided per
wall. The back of the weep holes should connect to the drain, be protected from
INTERWEST CONSTULTING GROUP
TIMBERLINE ROAD CORRIDOR IMPROVEMENT

clogging and be screened to prevent drain materials from falling out of the weep
holes. A manufactured drain such as Miradrain could be substituted for the drain
sand and gravel. Manufactured drains should be installed following the manufac-
turers recommendations.
Wall backfill should be placed in 8-inch maximum loose lifts, moistened to
within 2 percent of optimum moisture content and compacted to at least 95 percent
of standard Proctor maximum dry density (ASTM D 698). The placement and
compaction of fill should be observed and tested by a representative of our firm
during construction.
WATER-SOLUBLE SULFATES
Concrete that comes into contact with soils can be subject to sulfate at-
tack. We measured water-soluble sulfate concentrations in two samples from
this site. Concentrations measured were 0.01 percent. Sulfate concentrations
less than 0.1 percent indicate Class 0 exposure to sulfate attack for concrete that
comes into contact with the subsoils, according to the American Concrete Insti-
tute (ACI). For this level of sulfate concentration, ACI indicates any type of ce-
ment can be used for concrete that comes into contact with the soils. In our ex-
perience, superficial damage may occur to the exposed surfaces of highly per-
meable concrete, even though sulfate levels are relatively low. To control this
risk and to resist freeze-thaw deterioration, the water-to-cementitious material ra-
tio should not exceed 0.50 for concrete in contact with soils that are likely to stay
moist due to surface drainage or high water tables. Concrete should be air en-
trained.

SURFACE DRAINAGE
Performance of foundations are influenced by changes in subgrade mois-
ture conditions. Carefully planned and maintained surface grading can reduce
the risk of wetting of the foundation soils. Positive drainage should be provided
away from foundations. Backfill around foundations should be moisture treated
and compacted as described in Fill Placement.
LIMITATIONS
This report has been prepared for the exclusive use of Interwest Consult-
ing Group for the purpose of providing geotechnical design and construction cri-
teria for the Timberline Road Corridor Improvement project. It was prepared from
data developed during our field exploration, laboratory testing, engineering anal-
ysis and experience with similar conditions. The recommendations contained in
this report were based upon our understanding of the planned construction. If
plans change or differ from the assumptions presented herein, we should be
contacted to review our recommendations.
Although our borings were spaced to obtain a reasonably accurate picture
of subsurface conditions, variations not indicated in our borings are possible.
We should observe footing excavations to confirm soils are similar to those found
in our borings. Placement and compaction of fill, backfill, subgrade and other fills
should be observed and tested by a representative of our firm during construc-
tion.
We believe this investigation was conducted in a manner consistent with
that level of skill and care ordinarily used by members of the profession currently
practicing under similar conditions in the locality of this project. No warranty, ex-
press or implied, is made.
