The approximate location of the site is depicted on Figure 1. The purpose of our study was to evaluate the subsurface conditions and to provide design and construction recommendations regarding geotechnical aspects of the proposed project. This report presents the findings of our subsurface exploration, results of our laboratory testing, conclusions regarding the subsurface conditions at the site, and geotechnical recommendations for design and construction of this project. 2 SCOPE OF SERVICES The scope of our services for the project generally included: • Review of referenced background information, including aerial photographs, published geologic and soil maps, previous geotechnical evaluations, in-house geotechnical data, and available topographical information pertaining to the project site and vicinity. • Notification of Utility Notification Center of Colorado of the boring locations prior to drilling. • Drilling, logging, and sampling of two exploratory borings with a conventional track-mounted drill rigs within the project site equipped with continuous flight solid stem augers. Drilling one borings with in the vicinity of each of the launch and receiving pits. The borings depth ranged between approximately 14.3 and 14.5 feet bgs. The boring logs are presented in Appendix A. Approximate boring locations and profile are presented on Figure 2. • Performance of laboratory tests on selected samples obtained from the borings to evaluate engineering properties including in-situ moisture content and dry density, Atterberg limits, gradation, and unconfined compressive strength. The results of the laboratory testing are presented on the boring logs and in Appendix B. • Compilation and analysis of the data obtained. • Preparation of this report presenting our findings, conclusions, and geotechnical recommendations regarding design and construction of the project. 3 SITE DESCRIPTION AND PROPOSED CONSTRUCTION The project site is located east and west of CO-105 Highway, approximately 70 feet southeast of CO-105 and Davidson Street intersection. The approximate location of the site is depicted on Figure 1. We understand that 70-foot portion trenchless pipeline will be extended laterally from the Monument water pipeline to feed the Tri-Lakes Monument Fire Rescue station, using standard jack and auger bore method at depths of approximately 12 feet below the ground surface (bgs), ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 2 where the pipe will be located at approximately 8 and 11 feet below the ground surface at the receiving and launch pits, respectively. The launch pit will be located to the east of CO-105, where the surficial soil was covered with native grasses and weeds. The receiving pit will be located to the west of CO-105 highway and is bounded by a private property fence from the west. Surficial soil was covered with native grasses, and a high profile fiber cable was marked between the property fence and highway shoulder. 4 FIELD EXPLORATION AND LABORATORY TESTING On April 22, 2022, Ninyo & Moore conducted a subsurface exploration at the site to evaluate the existing subsurface conditions and to collect soil samples for laboratory testing. Our evaluation consisted of the drilling, logging, and sampling of two small-diameter borings referred to as Boring B-19 and B-20. Approximate boring locations are presented on Figure 2. Boring B-19 was drilled west of the CO-105 west-bound shoulder and within the vicinity of receiving pit with solid-stem augers to a depth of approximately 14.3 feet. Boring B-20 was drilled east of the CO-105 east-bound shoulder and within the vicinity of launch pit to an approximate of 14.5 feet bgs. Relatively undisturbed soil samples were collected at selected intervals. Descriptions of the soils encountered are presented in Appendix A. The soil samples collected from our subsurface exploration were transported to the Ninyo & Moore laboratory for geotechnical laboratory analysis. Selected samples were analyzed to evaluate the in-situ moisture content and dry density, Atterberg limits, gradation, and unconfined compressive strength. The results of the in-situ moisture and dry density tests are presented on the boring log in Appendix A. A description of each laboratory test method and results are presented in Appendix B. 5 GEOLOGY AND SUBSURFACE CONDITIONS 5.1 Geologic Setting The site is located within the Town of Monument approximately 2.5 miles east of the Rocky Mountains, within the Colorado Piedmont section of the Great Plains Physiographic Province. The Laramide Orogeny uplifted the Rocky Mountains during the late Cretaceous and early Tertiary Periods. Subsequent erosion deposited sediments east of the Rocky Mountains, including the Dawson Formation in the area. As a result of the regional uplift, approximately 5 to 10 million years ago, streams down-cut and excavated into the Great Plains forming the Colorado Piedmont ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 3 section (Trimble, 1980). Thorson and Madole (2003) describe the surficial deposits as middle alluvial-slope deposits (middle Pleistocene) consist of thin beds of brown poorly sorted sand and sandy pebble gravel. Bedrock mapped as Dawson Formation was mapped underlying the alluvial deposits. The site and vicinity was mapped by Hart (1973-1974) as having low to moderate swell potential. 5.2 Subsurface Conditions Our understanding of the subsurface conditions at the project site is based on our field exploration and laboratory testing, review of published geologic maps, historic aerial photographs, and our experience with the general geology of the area. The following sections provide a generalized description of the subsurface materials encountered. Approximate borings locations are presented on Figure 2. More detailed descriptions are presented on Figure 2 (boring profile) and boring logs in Appendix A. 5.2.1 Alluvium Alluvium was encountered below approximately 1-inch thick topsoil in Boring B-19 and extended to a depth of approximately 6 feet bgs. Alluvium encountered consisted of gray, loose, moist to wet, silty sand with blow counts (i.e. the number of times a 140-pound hammer was dropped from 30 inches to drive the soil sampler 1-foot into the ground) varying from 13 blows per foot (bpf) to 15 bpf. Alluvium was also encountered in Boring B-20 below approximately 1-inch thick topsoil and extended to a depth of approximately 6 feet bgs. Alluvium encountered in Boring B-20 consisted of gray and black, loose to medium dense, moist, clayey sand. The alluvium encountered exhibited blow counts ranging from 14 to 34 bpf. Based on the results of the laboratory testing, selected samples of the alluvial deposits had in-place moisture contents between approximately 11.5 and 19.4 percent and dry densities between approximately 102.1 and 121.6 pounds per cubic feet (pcf). 5.2.2 Dawson Formation Bedrock mapped as Dawson Formation (Thorson and Madole, 2003) was encountered below the alluvial deposits in each boring, and extended to the borings termination depths of approximately 14.3 to 14.5 feet bgs. The top of bedrock was approximately 6 feet bgs in both borings. ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 4 The bedrock encountered generally consisted of various shades of gray, orange and red, moist to wet, moderately to strongly cemented clayey sandstone. Based on the results of the laboratory testing, selected samples of the Dawson Formation bedrock had in-place moisture contents between approximately 8.2 and 14.4 percent and dry densities between approximately 115.4 and 119.7 pcf. 5.3 Groundwater An attempt to measure groundwater levels was performed during drilling operations. At that time, shallow groundwater was encountered at 2 feet bgs in Boring B-19 and 8 feet bgs in Boring B-20. Groundwater levels will fluctuate due to seasonal variations in the amount of rainfall, runoff, water level of nearby creeks, groundwater withdrawal from adjacent sites, and other factors. The possibility of groundwater level fluctuations and perched water should be considered when developing the design and construction plans for the project. 6 CONCLUSIONS Based on the results of the subsurface evaluation, laboratory testing, and data analyses, it is our opinion that the proposed project is feasible from a geotechnical standpoint but will be complicated due to the presence of variable subsurface conditions and shallow groundwater encountered at the launch and receiving pits. Geotechnical design and construction considerations for the proposed project include the following: • Alluvium was encountered below approximately 1-inch thick topsoil in Boring B-19 and extended to a depth of approximately 6 feet bgs. Alluvium encountered consisted of a gray, loose, moist to wet, silty sand with blow counts varying from 13 to 15 bpf. • Alluvium was also encountered in Boring B-20 below approximately 1-inch topsoil and extended to a depth of approximately 6 feet bgs. Alluvium encountered in Boring B-20 consisted of gray and black, loose to medium dense, moist, clayey sand. The alluvium encountered exhibited low blow counts ranging from 14 to 34 bpf. • Bedrock mapped as Dawson Formation (Thorson and Madole, 2003) was encountered below the alluvial deposits in each boring, and extended to the borings termination depths of approximately 14.3 to 14.5 feet bgs. The top of bedrock was approximately 6 feet bgs in both borings. • An attempt to measure groundwater levels was performed during drilling operations. At that time, shallow groundwater was encountered at 2 feet bgs in Boring B-19 and 8 feet bgs in Boring B-20. Groundwater levels will fluctuate due to seasonal variations in the amount of rainfall, runoff, water level of nearby creeks, groundwater withdrawal from adjacent sites, and other factors. The possibility of groundwater level fluctuations and perched water should be considered when developing the design and construction plans for the project. • Based on our understanding of the subsurface conditions and review of the project ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 5 documents, pipe-jacking operations may be complicated by the presence of shallow bedrock (strongly cemented, sandstone bedrock) at the launch and receiving pit locations and may be further complicated by the presence of shallow groundwater. • The on-site soils should generally be excavatable with moderate to heavy-duty earthmoving or excavating equipment in good operating condition. It should be noted that the alluvial deposits at this site may contain cobbles, boulders, which could complicate excavations and increase wear and tear. • Site soils generated from on-site excavation activities consisting of alluvium that are free of deleterious materials, and do not contain particles larger than 3 inches in diameter, can generally be used as engineered fill during site grading provided they are moisture- conditioned and compacted as recommended in this report. Environmental factors that may restrict the re-use of on-site material was not studied in this report and should be discussed with the project environmental consultant. 7 RECOMMENDATIONS Based on our understanding of the project, the following sections present our geotechnical recommendations for design and construction of the proposed site improvements. If the proposed site improvements differ from the plans provided, it is important that Ninyo & Moore be notified and given an opportunity to reevaluate our recommendations prior to bidding the project for construction. Project specific structural plans were not available at the time of this report. 7.1 Earthwork The following sections provide our earthwork recommendations for this project. In general, the Town of Monument and El Paso County and/or project specific earthwork specifications are expected to apply, unless noted. 7.1.1 Excavations Our evaluation of the excavation characteristics of the on-site materials is based on the results of our subsurface exploration, our site observations, and our experience with similar materials. The on-site soils should generally be excavatable using medium- to heavy-duty earthmoving or excavating equipment in good operating condition. Although not encountered, the alluvial deposits at this site may contain cobbles and/or boulders, which could further complicate excavations and increase equipment wear and tear. Excavations within the Dawson Formation bedrock will be slow and will result in increased wear and tear on the equipment used. The excavations will be complicated by the presence of strongly cemented sandstone layers/lenses and groundwater. ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 6 The bedrock will be hard and brittle, and may break off in large sections. Equipment and procedures that do not cause significant disturbance to the excavation bottoms should be used. Excavators and backhoes with buckets having large claws to loosen the subgrade material should be avoided when excavating the bottom 6 to 12 inches of excavations as such equipment may disturb the excavation bases. 7.1.2 Temporary Excavations In our opinion, temporary slopes in the near-surface soils should be stable at a slope ratio of approximately 1:1 (horizontal[H]:vertical[V]); however, excavations into the clayey alluvium, particularly where groundwater is encountered, could result in significant sloughing. Temporary slopes should be evaluated in the field by a competent person in accordance with Occupational Safety & Health Administration (OSHA) guidelines. The near-surface site soils and Dawson Formation bedrock should be considered to be Type C and Type B soils, respectively, as evaluated by OSHA. Temporary excavations should conform with OSHA regulations. The contractor should provide safely sloped excavations or an adequately constructed and braced shoring system, in compliance with OSHA regulations, for employees working in excavations that may expose them to the danger of moving ground. Reducing the inclination of the sidewalls of the excavations, where feasible, may increase the stability of the excavations. If construction or earth material is stored, or equipment is operated near an excavation, flatter slope geometry or shoring should be used during construction. Due to the observed groundwater levels, wet or saturated conditions will be encountered at or near the excavation bases. The bedrock exposed at the bottom of the excavation may soften under the action of construction equipment. As a result, yielding, pumping, or rutting under construction equipment loads should be anticipated. Based on the presence of shallow (2 to 8 feet bgs) groundwater conditions encountered, construction dewatering will be needed when establishing the jacking and receiving pits. The dewatering design should account for variations in subsurface soil permeability and transmissivity, as well as the variability and depth to groundwater. The actual design, construction, and implementation of construction dewatering are the responsibility of the contractor, and should be performed by a qualified expert. Construction dewatering should be performed with care and so as not to cause harmful settlement of nearby foundations, utilities, or pavements. We recommend that adjacent improvements such as existing utilities or structures, be monitored prior to and during the dewatering process. ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 7 Discharge of water from the excavations to storm water collection system will require a Construction Dewatering Permit. The Colorado Department of Public Health and Environment Division of Water Quality requires the preparation of a combined application COG07000/COG315000/COG316000 45 days or more prior to discharge of construction dewatering to the public storm sewer system. 7.1.3 Re-Use of Site Soils Site soils generated from on-site excavation activities of alluvial deposits that are free of deleterious materials and organic matter, and do not contain particles larger than 3 inches in nominal diameter, can generally be used as engineered fill. Fragments of rock, cobbles, and inert construction debris concrete or asphalt) larger than 3 inches in diameter may be incorporated into the project fills in non-structural areas and below the anticipated utility installation depths. A Geotechnical Engineer should be consulted regarding appropriate recommendations for usage of such materials on a case-by- case basis when such materials have been observed during earthwork. Care should be taken to avoid nesting of oversized materials during placement. Recommendations provided in Section 203 of the current the Colorado Department of Transportation (CDOT) Standard Specifications for Road and Bridge Construction should be followed during the placement of oversized material. Excavated Dawson Formation claystone bedrock should not be incorporated into engineered fill. Additional evaluation and laboratory testing should be performed during earthwork activities to better evaluate the suitability of the on-site soils for re-use as engineered fill at this site. An evaluation of the potential for contamination by hazardous materials was beyond the scope of this study and the possibility of restrictions on full material importation and re-use due to environmental factors was not studied. 7.1.4 Imported Soil Imported soil for use as engineered fill should meet the requirements CDOT Class 1 structure backfill as presented in Section 703.08 of the 2021 CDOT Construction Specifications for Road and Bridge Construction. Imported soil should not contain organic matter, clay lumps, bedrock (claystone, sandstone, etc.) fragments, debris, other deleterious matter, or rocks or hard chunks larger than approximately 3 inches’ nominal diameter. ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 8 Imported soil for use as engineered fill should exhibit low corrosion potential. Imported soil placed in contact with ferrous materials should have a saturated soil resistivity of 2,000 ohm- cm or more and a chloride content of 25 parts per million or less. Soils in contact with concrete should exhibit a soluble sulfate content less than 0.1 percent. We further recommend that proposed import material be evaluated by the project’s geotechnical consultant at the borrow source for its suitability prior to importation to the project site. 7.1.5 Fill Placement On-site soils that classify as SC and SM or import soils used as engineered fill should be moisture-conditioned to moisture contents within 2 percent of optimum moisture content. Engineered fill should be placed in uniform horizontal lifts. Engineered fill should be compacted to a relative compaction of 95 percent, or more, as evaluated by American Society for Testing and Materials (ASTM) D698. Lift thickness for fill will be dependent upon the type of compaction equipment utilized, but should generally be placed in lifts not exceeding 8 inches in loose thickness. Fill materials should not be placed, worked, rolled while they are frozen, thawing, or during poor/inclement weather conditions. Compaction areas should be kept separate, and no lift should be covered by another until relative compaction and moisture content within the recommended ranges are obtained. 7.1.6 Controlled Low Strength Material Use of CLSM should be considered in lieu of compacted fill for areas with low tolerances for surface settlements, for excavations that extend below the groundwater table and in areas with difficult access for compaction equipment. CLSM consists of a fluid, workable mixture of aggregate, Portland cement, and water. CLSM should be placed in lifts of 5 feet or less with a 24-hour or more curing period between each lift. The use of CLSM has several advantages: • A narrower excavation can be used where shoring is present, thereby minimizing the quantity of soil to be excavated and possibly reducing disturbance to the near-by traffic; • Compaction requirements do not apply; • There is less risk of damage to improvements, since little compaction is needed to place CLSM; ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 9 • CLSM can be batched to flow into irregularities in excavation bottoms and walls; and • The number of workers needed inside the trench excavation is reduced. The CLSM mix design should be submitted for review prior to placement. The 28-day strength of the material should be no less than 50 pounds per square inch (psi) and no more than 150 psi. CLSM should be observed and tested by the geotechnical consultant. 7.1.7 Pipe Jacking We understand that conventional jack and bore method will be used as the trenchless method at CO-105 Crossing. In the conventional Jack and bore trenchless method, a casing or pipe is pushed or jacked in to prevent ground from collapse while drilling horizontally using a rotary auger. The sides of the launch and receiving pits shall be supported in such a manner as to prevent any movement or slippage of the earth during the jacking operations. The Contractor shall plan to use a casing lubricant, such as bentonite, in the event excessive frictional forces jeopardize the successful completion of the casing installation. Based on our understanding of the subsurface conditions and review of the project documents, pipe-jacking operations may be complicated by the presence of shallow bedrock (strongly cemented, sandstone bedrock) at the launch and receiving pit locations and may be further complicated by the presence of shallow groundwater. Figure 2 presents the subsurface conditions encountered on the site profile view to assist with the evaluation of the subsurface conditions encountered in relationship to the proposed pipe jacking operations. 7.1.8 Utility Installation The contractor should take care to achieve and maintain adequate compaction of the backfill soils around manholes, valve risers and other vertical pipeline elements where settlements commonly are observed. Use of CLSM should be considered in lieu of compacted soil backfill for areas with low tolerances for surface settlements. This would also reduce the permeability of the utility trenches. Pipe bedding materials, placement and compaction should meet the specifications of the pipe manufacturer and applicable municipal standards. Materials proposed for use as pipe bedding should be tested for suitability prior to use. ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 10 Special care should be exercised to avoid damaging the pipe or other structures during the compaction of the backfill. In addition, the underside (or haunches) of the buried pipe should be supported on bedding material that is compacted as described above. This may need to be performed with placement by hand or small-scale compaction equipment. Development of site grading plans should consider the subsurface transfer of water in utility trenches and the pipe bedding. Sandy pipe bedding materials can function as efficient conduits for re-distribution of natural and applied waters in the subsurface. Cut-off walls in utility trenches or other water-stopping measures should be implemented to reduce the rates and volumes of water transmitted along utility alignments and toward buildings, pavements and other structures where excessive wetting of the underlying soils will be damaging. Incorporation of water cut-offs and/or outlet mechanisms for saturated bedding materials into development plans could be beneficial to the project. These measures also will reduce the risk of loss of fine-grained backfill soils into the bedding material with resultant surface settlement. 7.2 Construction in Cold or Wet Weather During construction, the site should be graded such that surface water can drain readily away from the building areas. Given the soil conditions, it is important to avoid ponding of water in or near excavations. Water that accumulates in excavations should be pumped out or otherwise removed and these areas should be allowed to dry out before resuming construction. Berms, ditches, and similar means should be used to decrease stormwater entering the work area and to efficiently convey it off site. Earthwork activities undertaken during the cold weather season may be difficult and should be done by an experienced contractor. Fill should not be placed on top of frozen soils. The frozen soils should be removed prior to the placement of fill or other construction material. Frozen soil should not be used as engineered fill or backfill. The frozen soil may be reused (provided it meets the selection criteria) once it has thawed completely. In addition, compaction of the soils may be more difficult due to the viscosity change in water at lower temperatures. If construction proceeds during cold weather, foundations, slabs, or other concrete elements should not be placed on frozen subgrade soil. Frozen soil should either be removed from beneath concrete elements, or thawed and recompacted. To limit the potential for soil freezing, the time passing between excavation and construction should be minimized. Blankets, straw, soil cover, or heating may be used to discourage the soil from freezing. ---PAGE BREAK--- Ninyo & Moore I Monument Water Pipeline, CO-105 Trenchless Crossing, Monument, Colorado I 502071003 R I May 31, 2022 11 7.3 Construction Observation and Testing A qualified geotechnical consultant should perform appropriate observation and testing services during grading and construction operations. These services should include observation of any soft, loose, or otherwise unsuitable soils, evaluation of subgrade conditions where soil removals are performed, evaluation of the suitability of proposed borrow materials for use as fill, evaluation of the stability of open temporary excavations, evaluation of the results of any subgrade stabilization or dewatering activities, and performance of observation and testing services during placement and compaction of engineered fill and backfill soils. The geotechnical consultant should also perform observation and testing services during placement of concrete, mortar, grout, asphalt concrete, and steel reinforcement. If another geotechnical consultant is selected to perform observation and testing services for the project, we request that the selected consultant provide a letter to the owner, with a copy to Ninyo & Moore, indicating that they fully understand our recommendations and they are in full agreement with the recommendations contained in this report. Qualified subcontractors utilizing appropriate techniques and construction materials should perform construction of the proposed improvements. 8 LIMITATIONS The field evaluation, laboratory testing, and geotechnical analyses presented in this geotechnical report have been conducted in general accordance with current practice and the standard of care exercised by geotechnical consultants performing similar tasks in the project area.

Bulk Samples Bulk samples of representative earth materials were obtained from the exploratory borings. The samples were bagged and transported to the laboratory for testing. The Standard Penetration Test (SPT) Sampler Disturbed drive samples of earth materials were obtained by means of a Standard Penetration Test sampler. The sampler is composed of a split barrel with an external diameter of 2 inches and an unlined internal diameter of 1-3/8 inches. The sampler was driven into the ground 12 to 18 inches with a 140-pound hammer falling freely from a height of 30 inches in general accordance with ASTM D 1586. The blow counts were recorded for every 6 inches of penetration; the blow counts reported on the logs are those for the last 12 inches of penetration. Soil samples were observed and removed from the sampler, bagged, sealed and transported to the laboratory for testing. Field Procedure for the Collection of Relatively Undisturbed Samples Relatively undisturbed soil samples were obtained in the field using the following method. The Modified California Split-Barrel Drive Sampler The sampler, with an external diameter of 3.0 inches, was lined with thin brass rings with inside diameters of approximately 2.4 inches. The sample barrel was driven into the ground with the weight of a hammer in general accordance with ASTM D3550. The driving weight was permitted to fall freely. The approximate length of the fall, the weight of the hammer or bar, and the number of blows per foot of driving are presented on the boring logs as an index to the relative resistance of the materials sampled. The samples were removed from the sample barrel in the brass rings, sealed, and transported to the laboratory for testing. The California Drive Sampler The sampler, with an external diameter of 2.4 inches, was lined with four, 4-inch long, thin brass rings with inside diameters of approximately 1.9 inches. The sample barrel was driven into the ground with the weight of a hammer in general accordance with ASTM D3550. The driving weight was permitted to fall freely. The approximate length of the fall, the weight of the hammer, and the number of blows per foot of driving are presented on the boring logs as an index to the relative resistance of the materials sampled. The samples were removed from the sample barrel in the brass liners, sealed, and transported to the laboratory for testing. ---PAGE BREAK--- SOIL CLASSIFICATION CHART PER ASTM D 2488 PRIMARY DIVISIONS SECONDARY DIVISIONS GROUP SYMBOL GROUP NAME COARSE- GRAINED SOILS more than 50% retained on No. 200 sieve GRAVEL more than 50% of coarse fraction retained on No. 4 sieve CLEAN GRAVEL less than 5% fines GW well-graded GRAVEL GP poorly graded GRAVEL GRAVEL with DUAL CLASSIFICATIONS 5% to 12% fines GW-GM well-graded GRAVEL with silt GP-GM poorly graded GRAVEL with silt GW-GC well-graded GRAVEL with clay GP-GC poorly graded GRAVEL with clay GRAVEL with FINES more than 12% fines GM silty GRAVEL GC clayey GRAVEL GC-GM silty, clayey GRAVEL SAND 50% or more of coarse fraction passes No. 4 sieve CLEAN SAND less than 5% fines SW well-graded SAND SP poorly graded SAND SAND with DUAL CLASSIFICATIONS 5% to 12% fines SW-SM well-graded SAND with silt SP-SM poorly graded SAND with silt SW-SC well-graded SAND with clay SP-SC poorly graded SAND with clay SAND with FINES more than 12% fines SM silty SAND SC clayey SAND SC-SM silty, clayey SAND FINE- GRAINED SOILS 50% or more passes No. 200 sieve SILT and CLAY liquid limit less than 50% INORGANIC CL lean CLAY ML SILT CL-ML silty CLAY ORGANIC OL (PI > 4) organic CLAY OL (PI < 4) organic SILT SILT and CLAY liquid limit 50% or more INORGANIC CH fat CLAY MH elastic SILT ORGANIC OH (plots on or above “A”-line) organic CLAY OH (plots below “A”-line) organic SILT Highly Organic Soils PT Peat USCS METHOD OF SOIL CLASSIFICATION Explanation of USCS Method of Soil Classification PROJECT NO.

Response: If material delivery times do not meet the schedule, then no need to provide pricing for this bid alternative. 2. Question: Does the CDOT permit for the work adjacent to Hwy 105 require any CLSM backfill? Response: To our knowledge, this has not been required by CDOT. It is the contractor’s responsibility to ensure work within CDOT ROW is done in accordance with CDOT requirements and guidelines. 3. Question: Does the Town of Monument have a location for the spoils generated by the bedding zone? Response: Removal and disposal of excess materials shall be the responsibility of the contractor. 4. Question: Would the town be open to quantifying the asphalt required for trench patching (tons or square yard inches)? Response: Quantities of asphalt required for trench repair was intended to be incidental to water line construction and is included with the pipeline line item. However, for further transparency and clarity of bid pricing, additional line items have been added to the bid form for trench repair asphalt. Line item and quantity is presented in square yard-inch assuming a 5-inch asphalt depth for trench repair. Payment will be for actual quantities installed. 5. Question: Has the railroad permit been paid for by the Town of Monument? If not, do you know what that cost is? Response: The railroad permit has not been paid for. Permit fees can be charged to the Town as a pass through. 6. Question: Do any of the trees or brush need to be replaced that fall within a reasonable distance of the alignment? Response: We have not received any comments from permitting agencies indicating that trees and/or shrubs within the ROW need to be replaced. 7. Question: Where is the 12-Inch Check Valves? We can’t find them on the plans. The Measurement and Payment calls for a 12” Tideflex Valve which is used in a tank overflow piping scenario, I believe. Should it be some other valve? Response: They are located on sheet C-21, and C-31. We will follow up with the manufacturer and determine if an alternative valve type is more appropriate. ---PAGE BREAK--- Monument 2.0 MG Water Storage Tank – Clarifications for Add.
