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. CITY OF FORT COLLINS 1 ROLLAND MOORE PARK PICNIC STRUCTURES CTL I T JOB NO. FC-3027 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. CITY OF FORT COLLINS 2 ROLLAND MOORE PARK PICNIC STRUCTURES CTL I T JOB NO. FC-3027 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 0 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 CITY OF FORT COLLINS 8 ROLLAND MOORE PARK PICNIC STRUCTURES CTL I T JOB NO. FC-3027 IF 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.
