26, 2019. Liquidated damages of Nine-Hundred dollars and Zero cents ($900.00) per
calendar day shall be paid if project is not completed by that deadline.
A. Time for Completion. It is hereby understood and mutually agreed, by and between
the Contractor and the County, that the date of beginning Project work and the time
of completion as specified herein are essential conditions of the Contract. The
Contractor agrees that said Project shall be prosecuted regularly, diligently, and at
such rate of progress as will ensure completion within the time(s) specified. It is
expressly understood and agreed, by and between the Contractor and the County, that
the time(s) for completion of the Project described herein are reasonable time(s) for
the completion of the Project, taking into consideration the average climatic
conditions prevailing in the locality of the Project.

essence in completing the Project, and that the Project Work Schedule and all dates
set forth therein and where in this Contract, an additional time is allowed for the
completion of the Project, the new time limit fixed by such extension shall be of the
essence of the Contract.
C. Liquidated Damages. Completion of the Project is of paramount importance to the
County. If any portion of the Project is not completed in accordance with any time
extensions granted by the County, the County will suffer damage, the extent of which
will be impractical and extremely difficult to estimate accurately. Therefore, as part
of the consideration for executing the Contract, it is hereby agreed that the Contractor
shall pay to the County the liquidated damage amounts specified in the Contract. This
particular provision shall not be construed as a penalty upon said Contractor for failing
fully to complete said Project as agreed in the Proposal and this Contract nor is it
intended, but as Liquidated Damages to compensate the County for all costs incurred
as a result of such breach of Contract.
D. Delays in Project Completion of Construction Phase. Subject to the terms of
"Excusable Delays", as contained in paragraph E of this Section, the Contractor
expressly agrees to pay the County as a reasonable estimate of just compensation for
damages contemplated with the clause, the amount set forth as liquidated damages for
each consecutive calendar day that completion is delayed in the construction of the
Project.
E. Excusable Delays - Force Majeure. If, by reason of Force Majeure, any party
hereto shall be rendered unable wholly or in part to carry out its obligations under this
Contract # 124.2019 Rev. 2018-10-10 btf
Budget Line Item # 111.54.96600.82011
20
Contract then such party shall give notice and full particulars of such Force Majeure
in writing to the other party within a reasonable time after occurrence of the event or
cause relied upon, and the obligation of the party giving such notice, so far as it is
affected by such Force Majeure, shall be suspended during the continuance of the
liability then claimed, but for no longer period, and any such party shall remove or
overcome such inability with all reasonable dispatch. The term Force Majeure as
employed herein, shall mean acts of God, strikes, lockouts, or other industrial
disturbances, acts of public enemy, orders of any kind of the Government of the
United States or the State of Colorado or any political subdivision, except the County,
or any civil or military authority, insurrection, riots, epidemics, landslides, lightning,
earthquakes, fires, hurricanes, storms, floods, washouts, droughts, arrests, restraint of
government and people, civil disturbances, explosions, breakage or accidents to
machinery, pipelines, or canals, or other causes not reasonably within the control of
the party claiming such inability. It is understood and agreed that the settlement of
strikes and lockouts shall be entirely within the discretion of the party having the
difficulty, and that the above requirement that any Force Majeure shall be remedied
with all reasonable dispatch shall not require the settlement of strikes and lockouts by
acceding to the demands of the opposing party or parties when such settlement is
unfavorable to it in the judgment of the party having the difficulty.
F. Cumulative Remedy. The liquidated damages referred to herein are intended to be
and are cumulative and shall be in addition to every other remedy now or hereafter
enforceable at law, in equity, by statute, or under Contract.

construction. Maintain the temporary unbonded length of proof test ground nails open for subsequent grouting.
In some granular soils with an open matrix with no cohesion, the potential for drill hole collapse or grout leakage
may be large. In this case, the use of a grout “sock” may be used as approval by the Engineer to prevent the
collapse of the drill hole and to reduce grout flow into the highly-permeable soil.

GROUND NAIL TESTING
504.31 Both verification and proof testing of designated test ground nails shall be performed. One proof and one
verification test shall be performed on a production or sacrificial ground nails at locations selected by the
Engineer or as shown on the plans. Testing of a ground nail shall not be performed until the ground nail grout and
shotcrete facing have cured for at least 72 hours or attained their specified 3-day compressive strength.
The Contractor shall provide all necessary equipment to perform the ground nail. The Contractor shall also have
calibrated back up gauges and equipment to minimize down time due to testing equipment failure. The pressure
gauge shall be graduated in 200 psi increments or less. The ground nail head movement shall be measured with a
minimum of 1 dial gauge capable of measuring to 0.001 inch.
Preliminary results shall be submitted to the Engineer within 24 hours of the test completion. A full report
containing test load results shall be submitted to the Engineer within 5 working days of the test completion.
504.32 Verification Testing of Sacrificial Ground nails. Verification testing shall be performed on sacrificial
test ground nails. Verification testing shall be performed prior to installation of production ground nails to
confirm the appropriateness of the Contractor’s drilling and installation methods and verify the required ground
nail pullout resistance.
Sacrificial test ground nails shall be placed and constructed to mimic production nails. The minimum bonded
length of the ground nail during verification tests, LBVT, shall be 9 feet.
The maximum bonded length LBVTmax is defined as:
LBVTmax = (CRT•At•fy)/(QALL•FSTver)
where,
CRT = Reduction coefficient. Use CRT = 0.9 for Grade 60 and 75 bars. If the Engineer allows Grade
150 bars on the project, use CRT = 0.8;
At = Nail bar net cross-sectional area after threading;
fy = Nail bar yield tensile strength for Grade 60 and 75 bars or ultimate tensile strength if Grade
150 bars;
QALL = Allowable pullout resistance per unit length (QALL = Qu/FSP), use 1508 lb/ft; and
FSTver = Factor of safety against tensile failure during verification tests (use 2.5).
The DTL shall be calculated based on the test nail’s as-built bonded lengths.
The Design Test Load (DTL) shall be determined as follows:
DTL = LBVT • QALL
where,
LBVT = As-built bond length in feet.
QALL = Allowable pullout resistance per unit length (QALL = 1508 lb/ft)

REVISION OF SECTION 504
GROUND NAILS
Verification tests are conducted according to the loading schedule of Table 504-1. Each load increment is held
until movement stabilizes. The Contractor must record ground nail movements at each load increment and the
time intervals shown in the table for each load step. Creep tests are performed at 1.50 times the design test load
(DTL). The alignment load (AL) should be the minimum load required to align the testing apparatus and shall not
exceed 5 percent of the DTL. Set dial gauges to “zero” after applying the alignment load. Following application of
the maximum load, reduce the load to the alignment load and record the permanent set.
Hold each load increment until stable. Monitor the verification test ground nail for creep at the 1.50 DTL load
increment by measuring and recording ground nail movement. Maintain the load during the creep test within 2
percent of the intended load. The test results shall be presented in a report with cover letter and stamped by a
Colorado registered Professional Engineer for the Engineers review and acceptance prior to production. The
Engineer shall have 10 working days to review the report and based on the results, design modifications may be
required.

b. A proposed approach (basic description of how Proposer will proceed with this Service), timetable for the Service, and proposed method of compensation for services rendered.
Following approval of submittals and utility locates via CO 811, GSI will first mobilize subcontracted traffic control and a hydrovac service for potholing, along with our project manager for direction and oversight. Locations will be potholed to check actual location and depth of utilities at each site. GSI will install the sacrificial soil nails for verification testing (one at each site) during this initial mobilization, immediately following potholing activities. GSI anticipates that the Owner’s Engineer will have the opportunity to review utility locations and revise the plans as needed during the grout curing period (up to 3 days) for the verification test nails.
GSI will re-mobilize to the site to perform the verification tests and, upon successful completion, immediately begin installation of the production soil nails. GSI plans to use an excavator-mounted drill rig to install the ground anchors from one lane of roadway width, under continuous traffic control (one active lane) during working hours. The excavator-mounted drilling operation will be supported by GSI technician’s on-slope with rope-supported access as needed.
GSI plans to utilize 40mm hollow-bar soil nails for this project. We understand that the hollow-bar soil nails must be coated for corrosion protection, and end hardware must be galvanized. Upon completion of the top row of soil nail installation, GSI will anchor the Tecco mesh in place and drape over the lower slope area, then install the lower row(s) of soil nails. The surface of the slope will be depressed around each soil nail head and the end hardware will be torqued to ensure a fully tensioned system upon completion.
GSI’s Superintendent will lead (a) development of the project- and site-specific safety plan with input and support from GSI’s Mountain Region Safety Technician and Project Manager; and (b) the daily morning tailgate meeting to plan the day’s work tasks and cover relevant safety briefings and task hazard analyses. During the work, GSI’s Superintendent will be in direct and continuous communication – radio or direct verbal – with the traffic control personnel to allow for immediate passage of emergency response vehicles, avoid delays for off-schedule school buses or similar community needs, and mitigate the risk associated with “pass-through” traffic and disobedience of the established traffic control.
GSI’s proposed linear project schedule for this work is as follows:• Submittals: 2 weeks prior to mobilization• Potholing and Verification Testing: 4 working days• Gerbaz Way Site:• Soil Nail Installation – 2 working days• Mesh Installation – 1 working day• Guardrail Removal and Replacement - 1 to 2 working days• Maroon Creek Site:• Soil Nail Installation – 5 working days• Mesh Installation – 2 working days
With this anticipated work duration, GSI has flexibility to plan the mobilization date at a time convenient to the public and our work schedule, and will have no issue finishing the work prior to the required completion date of July 26, 2019.

contracting and design throughout the United States and Canada. Our slope and landslide repair
portfolio is extensive in the geotechnical construction industry and contains over 3,600 slope,
retaining wall, and slide corrections.
GSI is uniquely qualified for geohazard mitigation due to its primary focus on slope, landslide,
and retaining wall stabilization projects using soil nails. GSI also employs technologies such as
tiebacks, ground anchors, micropiles, rock anchors, rock bolts, rock dowels, compaction grouting,
wire and cable net drapery, rock fall and debris flow catchment systems, and shotcrete.
GSI is currently operating a minimum of forty-five (45) 3-4-man crews, each having successfully
stabilized at least five geohazards. The crews are streamlined for rapid mobilization by having
the majority of the required equipment on a flatbed trailer and support truck. Specialized heavy
equipment is typically mobilized in advance of field personnel to be on site and ready for operation.
Other equipment (forklifts, small excavators, dozers, etc.) are readily available from rental facilities
near the sites. GSI maintains warehouses with material inventory of hollow-bar soil nails, solid all-
thread bar, nuts, and plates to reduce the dependency on material vendors to meet our immediate
response needs.
With our “tool box” of innovative equipment and techniques, we are equipped to manage any
site in any location, no matter how difficult the access may be. GSI owns and operates a fleet
of over 30 excavator-mounted SuperNailers ™, the drill rig to be utilized for this project, and
most frequently used by GSI. GSI’s fleet of specialty equipment extends well beyond excavator-
mounted SuperNailers™ – we own and operate dozens of wagon and pallet drills, Menzimuck
Spider excavators, hand drills, crane basket drills and personnel carriers, Soil Nail Launcher™, as
well as supporting equipment such as grout plants, air compressors, and shotcrete pumps.
GSI credits its success to the founding philosophy of serving the client with the best technologies,
the best solutions, and the fastest possible service. Through many years of training, experience, and
this founding philosophy, GSI’s project managers and constructors are among the most qualified
and most experienced in our industry.

Project Description:
GSI was selected to provide design-build services
for a 190 lineal foot section of roadway that
parallels West Divide Creek located in Mesa
County, Colorado. The failed outboard slope of
roadway limited the width of the roadway down
to one lane. GSI’s design-build approach included
soil nail paired with steel reinforced shotcrete for
lateral support of the roadway and hillside. The
soil nails also provided temporary support of the
excavation, so a single lane of the roadway could
remain open during construction for emergency
access. Micropiles were installed approximately
20 feet down the outboard slope to provide
bearing support to the GCS® wall backfill that
would provide an additional 15 feet of roadway
width. The roadway is now wide enough to accept
two-way traffic.

Road and Gerbaz Way have one lane in each direction, one lane will have to be
shut down for the entirety of each work day. Is this allowed?
● Response: One lane of traffic must be maintained during working hours. At
the end of each day both lanes shall be open to traffic.
17. Question: Will access be allowed at the bottom of the slope?
● Response: No, unless the contractor obtains permission from the private
property owners.
18. Question: Is there a buy America requirement for this project?
● Response: No
19. Question: Who is responsible for tree removal from the slopes?
● Response: None anticipated or being budgeted
20. Question: Are the slopes required to be cleared of all vegetation prior to
placement of mesh?
● Response: Just bring to flush to allow for proper, tight installation and then
plan on allowing vegetation to grow back naturally
21. Question: Is there any utility work for which the contractor will be responsible?
● Response: A potholing line item has been included in the project to locate
the water line that feeds the City of Aspen Water Plant. This is the only
utility work expected at this time.
22. Question: Is there any geotechnical information available?
● Response: An inclinometer was installed in 2016 at the Maroon Creek Road
site. This report will be made available.
23. Question: Is the sediment shifting because of a leak in the pipe?
● Response: Cannot answer without/prior to drilling access
24. Question: How far is the Maroon Creek Road site from the diversion structure?
● Response: Roughly 1.75 miles
25. Question: How deep beneath the road is the waterline?
● Response: Varies between 5’-12’ along the road
26. Question: What method was used to locate the water lines?
● Response: mix of resources including, but not limited to, multi and single
wave locators.
27. Question: When will potholing hours begin? At mobilization of upon arrival to
site?
● Response: Arrival to site assuming crew is ready to work upon arrival
28. Question: Will the material pulled from the potholing efforts be returned to the
hole after work is performed?
● Response: No; it will need to be disposed of.
29. Question: Can the slurry from potholing go to the landfill?
● Response: Yes – likely needs to be dry before brought to landfill
30. Question: RFP packet mentions contract will include options for 4 additional
years of extension. Does the County intend to award repairs for up to 5 years?
● Response: No – the award will be for the scope included in this RFP only
31. Question: Is builder’s risk insurance required for this project?
● Response: We will not require Builder’s Risk for this project
32. Question: Who is responsible for tree removal?
● Response: We do not anticipate the need for any tree removal. Grubbing and
trimming vegetation only.
33. Question: What bid item covers grubbing?
● Response: There is not a specific bid item for this as we anticipate the efforts
to be very minimal. Any tree/shrubs in the project area will be less than 6” in
diameter and only needs to be brought flush/low enough to the surface to
allow the mesh to lie flat on the landscape.
34. Question: In drawing 2, division 600 references a survey tab sheet. I cannot locate
it in the documents. Is it going to be included?
● Response: No; only referenced for architectural/surveying reporting
purposes
35. Question: Are the nail locations to be interpreted as surveyed and for precise
placement
● Response: No. They are general references. Once the bounds are established,
nails should be placed similarly and functionally but may be adjusted to
account for the contour and makeup of the landscape.
36. Question: Can there be grout left on the slope if over pour occurs but it does not
reach the river?
● Response: Minimal will be accepted. Large clusters or anything that is
visible to the public/adjoining property owner will need to be removed.
37. Question: Is there water accessible and provided by the County at each site?
● Response: City of Aspen owns and controls hydrants. Will need to reach out
to the City of Aspen.
38. Question: Are there identifiable laydown areas near the project sites that
contractors will be able to use?
● Response: There are several options available within a few tenths of a mile
from each project site
39. Question: Who is the property owner below the Gerbaz Way site location?
● Response: Ownership may be obtained via Pitkin County’s GIS page on our
website
40. Question: What percentage of anchors/nails will require testing?
● Response: Not defined as percentage. PER SITE: One (1) for verification
and One (1) for proofing.
41. Question: Do you anticipate separate mobilization for installation, verification,
then proofing or just one and move as swiftly as possible?
● Response: Just one mobilization. Allow 3-4 days for grout to cure and then
verify/proof
42. Question: Has the County identified a geotechnical engineer to consult for this
project?
● Response: Yes - Richard Johnson
43. Question: Drawing 2 - Division 600 - Note 1 refers to survey tabulation sheet.
None is provided. Please advise. What is anticipated in the survey bid item?
● Response: No survey tabulation will be provided. Contractor’s surveyor will
be responsible for providing sufficient layout information to construct the
project per the plans.
44. Question: Drawing 4 - Please review plan and profile as they do not appear to
match. Please advise.
● Response: Plan and profile views are dimensionally correct. Stationing will
be corrected in construction plans.
45. Question: What bid item should remove guard rail be included in?
● Response: Removal of Guardrail Line Item has been added to the Bid
Schedule. Please use this line for the rail and existing end sections.
46. Question: What bid item should clear & grub be included in?
● Response: There is not a specific bid item for this as we anticipate the
efforts to be very minimal. Any tree/shrubs in the project area will be less
than 6” in diameter and only needs to be brought flush/low enough to the
surface to allow the mesh to lie flat on the landscape.
47. Question: 504.32 - I calculated the maximum verification test bond lengths to be
9.9 feet for the 40 kip yield bar and 13.89 feet for the 60 kip yield bar. If you use
10 feet and 15 feet as the bond length you get 15.08 kips and 22.62 kips as DTL.
This is fine if you only want to test the upper portion of nail or just confirm the
bond strength. 504.33 says to proof DTL is to be the same as the verification test
DTL. Again this is fine if you want to test the nails to very low loads. Is this what
is intended or am I missing something?
● Response: Correct, soil nail testing should be designed to test the bond
strength. The bond strength is an assumed value for the design and is critical
to the performance of the wall. We know the strength of the bar, shotcrete,
rebar and grout. The bond strength is assumed and unknown. The DTL is
based on the assumed bond strength, design hole diameter and bond length.
The DTL is independent of what test is being performed. I simplified the
calculation to DTL=1508 lb/ft*Bond Length. The difference is that the
verification testing goes to 2.0*DTL and proof testing goes to 1.5*DTL. In
addition, the maximum test load should not exceed 90% of the bar yield.
48. Question: Is soil nail grout testing required and if so who is handling the testing?
● Response: Yes, grout testing shall be performed by the Contractor. One set
of samples per day of grouting will be required.
49. Question: May equipment be parked at Pitkin County yard at 76 Service Center
road overnight and weekends?
● Response: 76 Service Center Road is not available, however other areas may
be used for construction staging, including Buttermilk Parking Area

1.0 PROJECT INFORMATION
1.1 Purpose and Scope
This report presents the results of our geotechnical investigation and evaluation of observed
roadway distress near milepost 1.8 on Maroon Creek Road in Pitkin County, approximately 2.5
miles west of Aspen, Pitkin County, Colorado (Figure 1). The purpose of this study was to
investigate geotechnical characteristics of subsurface soils and bedrock to provide information
on the roadway distress and apparent movement at the project site. The investigation consisted
of field reconnaissance, exploratory drilling, inclinometer installation and monitoring, and
laboratory testing of subsoils encountered.
1.2 Site Conditions
The project area included a portion of Maroon Creek Road from approximately mile 1.7 to mile
1.9. Apparent distress in the roadway at the project area was observed as pavement damage
including horseshoe cracking and settlement of pavement down towards Maroon Creek to the
northwest as shown in Photo 1. The project site is located on the roadway approximately 30
feet above Maroon Creek and 0.5 miles southwest of the entrance to Aspen Highlands ski area.

Pitkin County, Colorado
2
Maroon Creek Road in the project area was gently sloping down to the southwest at an
estimated grade of 3 percent. In the area of roadway distress, the slope between Maroon Creek
Road and Maroon Creek was at grades near 40 percent, sloping down to the northwest. Above
the road the hillside was steep to very steep, sloping from the southeast down to the northwest
at grades of approximately 35 percent to 50 percent. The elevation along Maroon Creek Road
at the project site was approximately 8010 feet. The area adjacent to the project site was
vacant land with native vegetation, including bushes and trees. Approximately 110 feet uphill
and east of the road was Exhibition Lane, a residential street. A newly constructed, two story
wood frame home sits at the top of the slope directly above and east-southeast of the road.
Approximately 30 feet downhill and northwest of the road is Maroon Creek.
1.3 Site Geology
The project area was located in the valley of Maroon Creek approximately 2.5 miles south-
southwest of the confluence of the creek with the Roaring Fork River and approximately 1.3
miles northeast of the confluence with Willow Creek. The valley was bounded on the north and
west by the east end of Burnt Mountain, a nearly east-west trending ridge, and on the south and
east by Aspen Highlands Ski Area on Highland Peak. Based on geologic maps by others, the
area was underlain by the red-brown siltstone, sandstone and conglomerate of the
Triassic/Permian age State Bridge Formation. This formation is exposed in outcrops in the
slopes and cliffs in and adjacent to the project area. Surficial deposits at the site have been
mapped by others as artificial fill, alluvium from stream channel deposits, colluvium of material
ranging in size from fine grained to boulders, and poorly sorted, unconsolidated gravel, sand
and silt of glacial origin.
2.0 SITE INVESTIGATION
2.1 Subsurface Investigation
One test hole was drilled on December 8, 2015 in the southbound shoulder of Maroon Creek
Road in the area of observed road distress. The test hole location was suggested by a
representative of Pitkin County and was refined by Yeh personnel in the field based on safety
and to provide a functional one lane roadway during drilling. An inclinometer was installed in
the test hole to monitor subsurface slope movement. The test hole depth was 65 feet below
existing grades. The location of the test hole is presented in Figure 2.
Maroon Creek Road Distress Project No. 215-202
Pitkin County, Colorado

The test hole was advanced with a CME 75 truck mounted drill rig using the ODEX drilling
method as shown in Photo 2. At selected intervals, a standard split spoon sampler with a 1 -
inch inner diameter (I.D.) and 2 inch outer diameter (O.D.), were used to record blow counts and
obtain samples. The sampler was seated at the bottom of the test hole, then advanced by a
140 pound hydraulic automatic, or “auto,” hammer falling a distance of 30 inches. The number
of blows required to drive the sampler 12 inches constitutes the N-value. The N-value, when
properly evaluated, is an index of the consistency or relative density of the material tested. The
test hole log and legend are presented in Appendix A.

2.2 Subsurface Conditions
In general, the subsurface conditions in the project site consisted of approximately 23 feet of fill
materials that included silt, clay, sand, gravels, occasional cobbles and boulders, and fill debris
over 2 feet of native sand. Fill soils from 9 to 23 feet below surface grade contained glass,
metal, and debris likely associated with historic mining activity. The native granular materials
were underlain by an estimated 21.5 feet of weathered bedrock over sandstone bedrock to the

depth drilled. Weathered bedrock had the appearance of bedrock fragments with a silty sand
matrix as shown in Photo 3.
Photo 3. Highly weathered bedrock material encountered at 30 feet below grade.
Two fill sand samples tested had 28 to 29 percent fines (material passing the No. 200 sieve).
Atterberg limit testing on one of these samples indicated a liquid limit of 32 percent and a
plasticity index of 8 percent. One weathered bedrock sample had a liquid limit of 20 percent
and a plasticity index of 6 percent.
One fill sand sample tested, classified as SM, according to the Unified Soil Classification
System (USCS) and as A-2-4, based on the American Association of State Highway
Transportation Officials (AASHTO). Results of the laboratory testing and the Summary of
Laboratory Test Results are presented in Appendix B.
2.2.1 Groundwater
Groundwater was encountered during drilling at 45 feet below existing grade. Variations in
groundwater conditions may occur seasonally. The magnitude of the variation will be largely
dependent upon the adjacent Maroon Creek River water levels, the amount of spring snowmelt,
duration and intensity of precipitation, site grading changes, and the surface and subsurface
Maroon Creek Road Distress Project No. 215-202
Pitkin County, Colorado
5
drainage characteristics of the surrounding area. Perched water tables may be present, but
were not encountered during drilling.
2.3 Inclinometer
One inclinometer was installed in the exploratory test hole in the southbound lane shoulder,
near the edge of pavement, of Maroon Creek Road. Inclinometer casing measuring 3.34
inches O.D. was placed in the hole and the annulus was filled with grout. Inclinometer
measurements have been recorded from December 11, 2015 to October 17, 2016 to evaluate
the movement and direction of a potential slip surface. Based on inclinometer readings to date,
the total depth below existing road grade to the base of the slip zone appears to be at
approximately 12 to 14 feet. Inclinometer graphs can be found in Appendix C. We recommend
additional inclinometer readings be performed at least twice a year. Additional data acquired
over time would increase the probability of seeing appreciable movement and better define a
movement direction.

3.0 SLOPE STABILITY ANALYSIS
A global slope stability analysis was performed for the existing slope configuration. The function
of the stability analysis is to estimate the global stability factor of safety (FS) of the subject
slope. The FS is the ratio of the resisting forces to the driving forces. An FS greater than 1.0
suggests a stable slope and less than 1.0 suggests a comparatively unstable slope. An FS of at
least 1.33 is typically sought for permanent slopes.
The slope stability of existing conditions was evaluated based on a review of the existing site
conditions, anticipated groundwater conditions, and available subsurface information. Based on
our geologic reconnaissance and our subsurface investigation, one cross section was used to
model existing conditions. The slope geometry for the cross section was developed using 2-foot
contour data available on the Pitkin County website. The cross section was taken perpendicular
to the slope near the center of the damaged pavement area. A similar cross section line was
also surveyed by Yeh personnel using a level and grade rod and used with the section
developed from the contour data. The cross section was modeled using the computer program
SLIDE developed by Rocscience. This program is a two-dimensional limit equilibrium slope
stability analysis program. An FS of 1.0 was modeled for the existing condition at the site to
represent the unstable slope, pavement cracking, and inclinometer movement. The strength
parameters used in the model are summarized in Table 1.

Stability analyses data can be found in Appendix D. Based on the results of our subsurface
investigation, inclinometer readings and analyses, we believe the unstable slope and pavement
damage are a result of a combination of an over steepened embankment placed during the
original road construction, loose, poorly compacted fill and debris in the embankment and
subgrade, saturation of the embankment during the wet season, and erosion of the toe of the
embankment by Maroon Creek.

The global stability analysis performed addresses the localized stability of the roadway
embankment extending downslope to Maroon Creek. Overall stability of the slope extending
above the roadway was not evaluated and is beyond the scope of this work.
4.0 MITIGATION OPTIONS
Unstable slope mitigation can be accomplished by increasing the resisting forces near the toe of
the slope or reducing the driving forces at the head of the slope. Resisting forces could be
increased by placing buttresses and/or installing ground anchors, including tiebacks near the
toe of the slope. Additionally, drilled shafts or micropiles could be installed near the top of the
slope to also increase the resisting forces. As previously discussed, the main factors that
contribute to the unstable slopes are the over steepened embankment materials, poor
compaction of fill soils and/or debris, groundwater infiltration during runoff months, and erosion
of the toe of the slope. We feel that mitigation should address these factors and increase the
factor of safety to an acceptable level.
5.0 ADDITIONAL ANALYSES
Yeh and Associates analyzed existing conditions to provide our opinion as to the cause, extent,
and magnitude of the unstable slope. In order to better define the slope movements, we would
recommend the following:
• Continue to monitor the inclinometer on at least a biannual basis in order to better
determine the depth and extent of the unstable mass.
• An additional inclinometer should be installed in the eastbound shoulder to evaluate
extents of poor fill, groundwater and potential slip surfaces.
• The global stability analyses should be refined when additional inclinometer data is
obtained.
If stability of the overall slope extending above the roadway is of concern, additional
investigation and analysis should be performed to evaluate the conditions of the slope.
