SCOPE
This report presents the results of our geotechnical investigation for the
Rolland Moore Park picnic structures. The park is located northwest of Drake
Road and South Shields Road in Fort Collins, Colorado. Two sets of timber picnic
shelters (Picnic Shelter #1 and #2) are located at the west end of the park entrance
road (Fig. 1). The City of Fort Collins Park Division is planning to remove the
existing timber picnic shelter structures and replace them with new metal
shelters.
We investigated the subsurface conditions in the vicinity of the picnic
shelters to provide geotechnical design criteria and construction
recommendations for the proposed construction. This report presents the results
of our field and laboratory studies and our conclusions, opinions and
recommendations regarding the proposed improvements. Our conclusions are
summarized below.
SUMMARY OF CONCLUSIONS
1. The soils we encountered generally consisted of stiff to very stiff,
moist, sandy clay fill over natural sandy clay, silty to clayey sand
and clayey gravel underlain by weathered to comparatively
unweathered claystone bedrock.
2. Ground water was measured in our borings at depths of
approximately 2 feet to 4 feet below the existing ground surface.
3. Based on past performance of existing shelter foundations and the
subsurface conditions encountered, we believe the new metal
fabricated shelters may be founded on footings or pads bearing on
natural soil. Geotechnical design criteria for footing foundations are
presented in the report.
4. Any excavations deeper than 2 feet will likely encounter soft or
saturated soil and/or ground water. Where ground water is
encountered in excavations, dewatering may be necessary.
Methods for dewatering excavations are presented in the report.

SITE CONDITIONS
Rolland Moore Park is an existing city park located northwest of Drake
Road and South Shields Road in Fort Collins, Colorado (Fig. 1). The existing
picnic structures are located on the west portion of the park at the west end of the
entrance road. An irrigation ditch is located west of Shelter #1 and south of
Shelter #2. A sidewalk/bike path is located east of Shelter #1 and north of Shelter
#2. The ground surface near Shelter #1 slopes down to the west toward the
irrigation ditch. The ground surface near Shelter #2 slopes down to the south
toward the irrigation ditch. The picnic shelters are bordered by a parking lot,
volleyball courts, entrance road and park open space.
The existing picnic structures consist of two sets of paired shelters with a
raised concrete planter between the paired shelters. According to design plans
by ZVFK Architects/Planners provided by the City, the four picnic shelters are
each 26 feet square. Each shelter consists of four concrete columns founded on
32-inch square and 12-inch thick footing pads, at each corner structure. The
columns support the roof framing which consists of laminate timber beams. The
east side of Shelter #1 and north side of Shelter #2 are cut into the ground
approximately 2 feet below existing grade. A 2 to 3 feet high concrete retaining
wall and stairs are located on the respective side of each shelter. The floor of
each shelter consists of a 4-inch concrete slab -on -grade.
PROPOSED RENOVATION
We understand that the laminate timber roof framing is deteriorating and
concrete near the top of the support columns is spalling off, causing reinforcing
steel to be exposed. We understand the city intends to remove the roofs, support
columns and footing pads of the existing structures without entirely removing the
existing slab -on -grade and concrete retaining walls. Once the existing shelters
are removed, the City is planning to construct new steel fabricated shelters at the
same locations.

SUBSURFACE CONDITIONS
Our borings penetrated 2 to 3 feet of stiff to very stiff, moist sandy clay fill
over medium stiff to stiff natural sandy clay and medium dense slightly silty sand
(TH-1), medium dense to dense clayey gravel (TH-2 and TH-3), and medium dense
clayey sand (TH-4). Two to 6 feet of weathered claystone was encountered in TH-
1, TH-2 and TH-4 at depths of 4 to 13 feet. Medium to very hard claystone bedrock
was encountered in each of the four borings at depths of 6 to 14 feet. Ground
water was encountered at depths of approximately 3 feet in the borings during
drilling. When the borings were checked the day after drilling, ground water was
measured at depths of 2 to 4 feet.
The approximate boring locations are shown on Fig. 1. Our borings were
drilled with a 4-inch diameter, continuous flight auger and a truck -mounted drill
rig. The drilling operations were observed by our engineer who logged the soils
and obtained samples for laboratory testing. Graphic logs of the soils found in
our borings including results of field penetration resistance tests are shown on
Figure 2. Results of our laboratory tests are presented on Figs. 3 through 5 and
are summarized in Table I.
Sandy clays and weathered claystone tested exhibited low swell. A sample
of claystone tested exhibited low plasticity and moderate swell. The clayey to
silty sands are considered to be non -swelling.
SHELTER CONSTRUCTION
Ground conditions and characteristics in the area of planned
improvements consist of stiff to very stiff sandy clay fill, medium stiff natural
sandy clay, medium dense slightly silty to clayey sand, and medium dense to
dense clayey gravel in the near surface deposits. Design plans for the existing
structures indicate the bottom of footing pads is 30 inches below the top of the
slab -on -grade. This suggests that the existing footing pads are founded on
natural sandy to gravelly clay and clayey to silty sand soils. We did not see
evidence of excessive movement of distress to the existing structures. It appears
CITY OF FORT COLLINS 3
ROLLAND MOORE PARK PICNIC STRUCTURES
CTL I T JOB NO. FC-3027

that the existing foundations (footing pads) have performed well over the life of
the structures. Therefore we believe the new metal fabricated shelters may be
founded with footings or footings pads bearing on natural soil.
Our investigation indicates the major constraint for reconstruction of the
picnic structures is the shallow water that has most likely developed since the site
development. Our recommendations for mitigation of the shallow water and
geotechnical design criteria for the footings or footing pads are presented below.
Footings. Based on the subsurface conditions encountered, we believe the
planned metal fabricated picnic shelters can be founded with footings or footing
pads bearing on the natural near surface soils. Footings or footing pads bearing
on the near surface clays and sands can be designed for a maximum soil bearing
pressure of 2,000 psf.
Footing bearing elevation should be a minimum of 30 inches below lowest
adjacent grade for frost protection. Footings or pads should have a minimum size
of 16 inches by 16 inches. These are minimum dimensions and larger footings
may be required to support foundation loads. Alternatively, the structures could
be founded using drilled footings that are at least 18 inches in diameter and 30
inches deep. Concrete could be poured "neat" into the drilled excavations. The
project structural engineer should design steel reinforcement for footings.
Soft, unstable soils and ground water may be encountered during
construction. Our recommendations for mitigating these conditions are included
below in the Ground Water section.
Prior to the placement of reinforcing steel or concrete, the base and sides
of the excavation should be clear of debris, trash, and loose soil. Loose soil
should be removed to expose firm natural soil or compacted in place to a
minimum 95 percent of the maximum dry density as determined in accordance
with ASTM D 698. Excavations should not remain open for more than 2 days. Soil
within the excavation should remain in a moist condition. Moisture conditioning
may be required prior to the placement of concrete.
CITY OF FORT COLLINS 4
ROLLAND MOORE PARK PICNIC STRUCTURES
CTL I T JOB NO. FC-3027
A representative of CTL I Thompson should observe the completed
foundation excavations prior to placing the forms to verify subsurface conditions
are as anticipated from our borings.
Lateral loads applied to footings or pads can be resisted by friction
between the concrete at the base of the footing or pad and the ground and by the
passive pressure of densely compacted backfill and/or undisturbed ground
against the sides of a footing or pad provided that soil will not be removed over
the life of the structure. A friction coefficient of 0.35 can be used between the
foundation concrete and the natural soil, backfill or bedrock. The passive earth
pressure against a footing or mat can be calculated using an equivalent fluid
density of 270 pcf for undisturbed soil or engineered fill.
Slab -on -Grade Floor Construction. We understand plans call for partial removal
of the existing slab -on -grade floors and construction of new concrete slabs in
some areas. Where new slabs are constructed, some differential movement
between existing slabs and new slabs should be anticipated.
The designer may wish to consider dowelled connections of the new slab
and existing slab interface. We do not recommend rigid connections between
foundation elements and slabs -on -grade. For new slabs -on -grade we recommend
the following additional precautions be observed. These precautions will not
eliminate slab -on -grade movement but will reduce the potential for damage due to
movement of slabs:
1. Slabs should be isolated from retaining walls, columns or other slab
penetrations.
2. New slabs -on -grade should generally be constructed in a manner
similar to the existing construction. For example, if a 6-inch gravel
section underlies the existing slab, a similar approach with the new
slabs will reduce the potential for differential movement between the
two slabs. A gravel layer is typically recommended where ground
water is within about 3 to 5 feet below the slab.
3. Frequent control joints should be provided in conventional slabs -on -
grade to reduce problems associated with shrinkage cracking and
curling. Panels that are approximately square generally perform
CITY OF FORT COLLINS 55
ROLLAND MOORE PARK PICNIC STRUCTURES
CTL I T JOB NO. FC-3027
better than rectangular areas. We advocate an additional joint about
3 feet away from and parallel to retaining walls.
Ground Water. Our borings, which were drilled in the winter (non -irrigation)
season, encountered water at depths as shallow as 3 feet. If construction is
planned during the irrigation season, or in wetter seasons or a wetter year, ground
water may be encountered at a shallower depth. Therefore we recommend the
contractor anticipate soft soils and wet conditions that will result from water
seeping into excavations for the foundations. Soft soils or unstable excavations
caused by localized seepage can be stabilized by crowding coarse aggregate
(such as CDOT No. 4 or No. 57) into the excavation using conventional
construction equipment. For excavations that will penetrate the ground water
surface, dewatering prior to excavation is recommended. Dewatering is
discussed in more detail below in the Excavation section.
ADDITIONAL CONSTRUCTION CONSIDERATIONS
Fill. We anticipated that minor amounts of fill may be necessary in areas where
existing grades have been disturbed by shelter removal activities. The area to
receive fill should be scarified, moisture -conditioned to within two percent of
optimum moisture content and compacted to at least 95 percent of standard
Proctor maximum dry density (ASTM D 698). The near surface, on -site soils can
be used as engineered fill providing they are free from organics, trash, or other
deleterious materials. If imported fill is needed, the soils should be low swelling,
sandy clays similar to the on -site soils, or granular soils. Highly plastic and
swelling clays and claystone are not desirable as imported fill because they may
cause problems associated with expansive soils. A sample of soils proposed for
import for fill should be submitted to our office for classification and approval
prior to hauling them to the site. We believe imported clay fill should be placed at
high moisture content to reduce the swell potential. Imported clay fills should be
moisture -treated to between optimum and 3 percent above optimum moisture
content, and sand fill or on -site soils within ±2 percent of optimum moisture
content. Fills should be compacted to at least 95 percent of standard Proctor
CITY OF FORT COLLINS 6
ROLLAND MOORE PARK PICNIC STRUCTURES
CTL I T JOB NO. FC-3027
IF
maximum dry density (ASTM D 698). The placement and compaction of
engineered fill should be observed and tested by our representative.
Excavations. Footing excavations in the near surface soils can be performed with
conventional trenchers or backhoes. Shallow ground water was encountered
below the site. We anticipate ground water will impact the proposed construction.
Ground water was measured at and above the existing footing elevations.
Medium dense clayey to silty sands and medium dense to dense clayey
gravels will likely be the predominant soils encountered during construction.
According to the Occupational Safety and Health Administration (OSHA) criteria,
the clayey sand and clayey gravel we encountered will classify as Type B soil,
allowing excavation slopes of 1:1 (horizontal to vertical). If ground water is
encountered and seeps from the slopes, this may require sloping for Type C soil
(maximum slope inclination of 1.5:1) and other precautions. The silty sand we
encountered will classify as Type C soil, requiring excavation slopes of 1.5:1
(horizontal to vertical). The contractor's "Competent Person" on site should
identify the soils encountered in excavations and refer to OSHA standards to
determine appropriate slopes.
Spoils piles should not be placed immediately adjacent to the excavations.
We recommend a distance back from the edge of the trench at least as great as
the depth of the trench.
Ground water was measured at depths of 2 to 4 feet below the existing
ground surface. Any excavations deeper than 2 feet will likely encounter soft or
saturated soil and/or ground water. Where ground water is encountered in
excavations, dewatering may be possible by sloping excavations to one or more
sumps where water can be removed by pumping. The sumps should be several
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 will likely result in destabilization of the base of the
excavation. The ground surface surrounding the excavation should be sloped to
direct runoff away from the excavation.
CITY OF FORT COLLINS 7
ROLLAND MOORE PARK PICNIC STRUCTURES
CTL I T JOB NO. FC•3027
We recommend excavation backfill be placed in thin, loose lifts, moisture
conditioned to within 2 percent of optimum moisture content and compacted to at
least 95 percent of standard Proctor maximum dry density (ASTM D 698) in areas
below the slab floor. In unpaved, undeveloped areas excavation backfill should
be compacted to at least 90 percent of standard Proctor maximum dry density
(ASTM D 698). The placement and compaction of fill and backfill should be
observed and tested by a representative of our firm during construction.
CONCRETE
Concrete that comes into contact with soils can be subject to sulfate
attack. We measured water-soluble sulfate concentrations in two samples from
this site. Concentrations were measured at 0.002 and 0.006 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 Institute (ACI). For this level of sulfate concentration, ACI indicates any
type of cement can be used for concrete that comes into contact with the
subsoils. In our experience, superficial damage may occur to the exposed
surfaces of highly permeable concrete, even though sulfate levels are relatively
low. To control this risk and to resist freeze -thaw deterioration, the water-to-
cementitious material ratio 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 entrained.
LIMITATIONS
We based the discussions in this report on our understanding of the
proposed development and planned structures; conditions disclosed by
exploratory drilling; review of maps, plans, and aerial photographs; site
observation; results of our laboratory tests; engineering analysis of field and
laboratory data; and our experience. The criteria presented in this report are
intended for aid in development decisions and preliminary planning purposes.
Future geotechnical engineering investigations and analysis are required to

formulate geotechnical design criteria for all structures, foundations, floors, and
for street pavement sections in parking lots and access drives.
Our borings were located to provide us the needed picture of the
underground based on plans known at the time of our investigation. Variations
between the borings will occur.
A representative of our firm should be present during site grading and
other construction to observe and test fill placement and foundation excavations.
We believe this investigation was conducted in a manner consistent with that level
of care and skill ordinarily used by geotechnical engineers practicing in this area
at this time. No warranty, express or implied, is made. If we can be of further
service in discussing the contents of this report or analyses of the influence of
subsurface conditions on the design of the proposed development, utilities,
structures and streets, please call.
