The new framing appeared to be in general conformance with the design and modification requirements. The city hired framing inspector questioned the floor joist changes to a different manufacturer. Based on our observation it appears that the framing is in general conformance with our plans and recommendations. Additionally, the PWI47's are adequate replacements for the RFPI20 and 40's and the roof specified as RFPI70's will be adequate as PW170's.

The connection consists of a 16 gauge Simpson LPCZ bracket with a bottom bearing plate and 4-8d nails top and bottom, plus 4- #8 toe screws each side of the beam. The total capacity for this combination is 2355 pounds downward and 1180 pounds upward, far in excess of the calculated design forces.

The Northwest Lakewood Sanitation District has no objections with the proposed development conditional on the items identified herein are fully addressed. The following are general requirements for sanitary sewer service. Rules, Regulations and Standards of the District must be complied with at all times. The subject lot appears to be entirely within the service and boundary area of the Northwest Lakewood Sanitation District. Treatment of sewage generated within the Northwest Lakewood Sanitation District is provided by Metro Wastewater Reclamation District. Existing District Sanitary Sewer Mainline(s) Northwest Lakewood Sanitation District has the following sanitary sewer mains in the vicinity of the proposed property: • 8 -inch mainline running south to north, east of the referenced property within Robb Street. It appears the 8 -inch mainline in Robb St. could service the property depending on the location of the sanitary service line in relation to the mainline. Connection to the mainline must be made with a Wye connection. It appears the property may be serviced by gravity flow; however, the owner/developer is responsible for determining horizontal locations and vertical depths of the existing sanitary sewer main(s) and potential conflicting utilities, to verify if service and gravity flow is feasible or if a private individual sewage ejector (lift station) is required. The issuance of a sewer tap permit by the District does not in any way guarantee that the property can be served by gravity flow. No underdrain or storm sump pump connections to District facilities are allowed. Utility Locates All projects must meet Colorado Revised Statue Title 9 for proper notification to the Notification Association by the Developer's professional engineer. It is also the owner's responsibility to include electronic locators on all new underground facilities, including service lines up to the structure or building being served. Submit details for tracer wire and associated test stations.

The proposed construction will consist of one to two story residence with basement. Laboratory tests were performed on selected samples to evaluate the engineering characteristics of various soil strata encountered in our boring. The results of our exploration, laboratory testing and engineering evaluation indicate the soils underlying this site have low expansive characteristics. Potential vertical movement on the order of 1-2 inches was estimated at the existing grade level for average moisture conditions. The proposed structure may be supported by spread or strip footings bearing at a minimum depth of three (3) feet below finished grade at the basement level, on 2 feet of select structural fill material that is moisture conditioned, placed and properly compacted. Design parameters for the foundations are included in this report. Groundwater seepage was encountered in the borings at the time of our field exploration. Detailed descriptions of subsurface conditions, engineering analysis, and design recommendations are included in this report. Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 1 1.0 INTRODUCTION This report presents the results of our subsurface exploration and foundation analysis for the proposed residence at 3273 Robb St. in Wheat Ridge, Colorado. The object ofthis investigation was to evaluate the physical properties of the soils underlying the site in order to provide recommendations for foundation, and retaining wall design, slab support and related earthwork for the structures. This geotechnical investigation was authorized by Workshop Denver. 2.0 PROJECT DESCRIPTION Terradyne understands that the proposed Residence will be a one to two story structure with basement, with a footprint of not more than 4000 square feet. If the final construction plans vary from what has been assumed, please contact Terradyne for further evaluation as the revisions may affect the recommendations provided in this report. 3.0 PURPOSE AND SCOPE OF SERVICES The purpose of our geotechnical investigation was to evaluate the subsurface and groundwater conditions of the site and provide geotechnical engineering recommendations for the design and construction of the residence. Our scope of services includes the following: 1) Drilling and sampling of one boring 13-1 to a depth of 25 feet; 2) Evaluation of the in-place conditions of the subsurface soils through field penetration tests; 3) Observation of the groundwater conditions during drilling operations; 4) Performing laboratory tests such as Atterberg limits, moisture content tests, free swell/consolidation tests; 5) Review and evaluation of field and laboratory tests; 6) Compilation, generalization and analysis of the field and laboratory data according to the project requirements; 7) Estimation of potential vertical heave; 8) Preparation of recommendations for the design and construction of the structures; 9) Consultations with Prime Professionals and members of the design team on findings and recommendations and the preparation of a written geotechnical engineering report for their use in the preparation of design and construction documents. The Scope of Services does not include an environmental assessment of the presence or absence of wetlands and/or hazardous or toxic materials in the soil, surface water, groundwater, or air, in the proximity of this site. Any statements in this report or on the boring logs regarding odors, colors or unusual or suspicious items or conditions are strictly for the information of the client. Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 2 4.0 SITE CONDITIONS The site for the proposed residence is located at 3273 Robb St, in Wheat Ridge, Colorado. The site is generally flat and is located on a vacant lot within a developed area. The site is bordered by adjoining property to the west, adjoining lots on the north and south, and Robb St. is to the east of the property. The boring location was established in the field by information provided by the client. 5.0 GEOTECHNICAL INVESTIGATION The field exploration to determine the engineering characteristics of the subsurface materials included a reconnaissance of the project site, drilling the boring, performing standard penetration tests and obtaining samples using Modified California sampler. One (1) soil test borings was drilled at the site. Boring B-1 was drilled to a maximum depth of 25 feet. Boring location at the lot was selected based on information provided by the client and established in the field by the drilling crew. An approximate boring location plan is shown on Figure 1 in the Appendix. The boring was performed with a drilling rig equipped with a rotary head. Conventional solid stem augers were used to advance the hole and samples of the subsurface materials were obtained using a Modified California sampler and standard 4.0 -inch augers. The samples were identified according to boring number and depth, encased in polyethylene plastic wrapping to protect against moisture loss, and transported to our laboratory. 5.1 Field Tests and Measurements Penetration Tests: During the sampling procedures, standard penetration tests were performed in the boring in conjunction with split -barrel sampling (ASTM 1586). The standard penetration value (N) is defined as the number of blows of a 140 -pound hammer, falling thirty inches, required to advance the split -spoon sampler one foot into the soil. The sampler is lowered to the bottom of the drill hole and the number of blows recorded for each of the two successive increments of six inches penetration. The "N' value is obtained by adding the second and third incremental numbers. The results of the standard penetration tests indicate the relative density and comparative consistency of the soils, and thereby provide a basis for estimating the relative strength and compressibility of the soil profile components. Water Level Measurements: Water level was noticed in Terradyne's soil boring during and after completion of drilling operations and is noted on the boring log. hi relatively pervious soils, such as sandy soils, the indicated elevations are considered reliable groundwater levels. hi relatively impervious soils, an accurate determination of the groundwater elevation may not be possible even after several days of observation. Seasonal variations, temperature and recent rainfall conditions may influence the level of the groundwater table and the volume of water encountered will depend on the permeability of the soils. Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 3 5.2 Boring Logs Field log was prepared for the boring. The log includes information concerning the boring method, samples attempted and recovered, the presence of various materials (such as clay, sand and silt) and groundwater observations. They also include an interpretation of the subsurface conditions between samples. Therefore, these logs include both factual and interpretive information. The final log represents our interpretation of the contents of the field log and laboratory test results for the purpose delineated by our client. The final log is included on Figures 2 & 3 in the Appendix. A key to classification terms and symbols used on the log is presented on Figure 4. 5.3 Laboratory Testing Program In addition to field exploration, a laboratory testing program was conducted to determine additional pertinent engineering characteristics of the subsurface materials that are necessary to evaluate the soil parameters. All phases of the laboratory testing program were performed in general accordance with the indicated applicable ASTM Specifications presented in Table No. 1. Table No. 1 Type of Test Applicable Test Standard Natural Moisture Content ASTM D-2216 Atterberg Limits ASTM D-4318 % Passing No. 200 Sieve ASTM D1140, D422 In the laboratory, each sample was examined and classified by a geotechnical engineer. As a part of this classification procedure, the natural water content of selected specimens was determined. Liquid and Plastic Limit tests were performed on representative specimens to determine the plasticity characteristics of the different soil strata encountered. The results of these tests are presented on the appropriate boring logs. 5.4 Laboratory Testing Program In addition to field exploration, a supplemental laboratory testing program was conducted to determine additional pertinent engineering characteristics of the subsurface materials that are necessary to evaluate the soil parameters.

The test boring log should be consulted for specific information at the boring locations. Groundwater was encountered in our boring at a depth of 10 ft below existing grade on boring 131. However, groundwater levels will fluctuate with seasonal climatic variations and changes in the land use. The low permeability of the soils may require several days for groundwater to enter and stabilize in the boreholes. It is not unusual to encounter shallow groundwater during or after periods of rainfall. Surface water tends to percolate through the surface until it encounters a relatively imperious layer. 6.0 FOUNDATIONS ON EXPANSIVE SOIL There are many plastic clays that swell when water is added to them and shrink when water is removed. Foundations constructed on these clays are subjected to large uplifting forces caused by the swelling. Two factors contribute to potential shrink -swell problems within a building site. Problems can arise if a) the soil has expansive or shrinkage properties or b) environmental conditions cause the moisture levels in the soil to change. Evaluation of the Shrink -Swell Potential of the Soils: Subsurface sampling, laboratory testing and data analysis is used to evaluate the shrink -swell potential of the soils under the foundations. The Mechanism of Swelling: The mechanism of swelling in expansive clays is influenced by a number of factors. The expansion in clays is a result of changes in the soil -water system that disturbs the internal stress equilibrium. Clay particles have negative electrical charges on their surfaces and positively charged ends. The negative charges are balanced by actions in the soil - water and give rise to an electrical interparticle force field. In addition, adsorptive forces exist between the clay crystals and water molecules, and Van Der Waals surface forces exist between particles. Thus, there exists an internal electro -chemical force system that must be in equilibrium with the externally applied stresses and capillary tension in the soil water. If the soil -water Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 6 chemistry is altered, either by changing the amount of water or chemical composition in the soil, the inter -particle force field will change. If the change in internal forces is not balanced by a corresponding change in the state of stress, the particle spacing changes until equilibrium is reached. This change in particle spacing manifests itself as a shrinkage or swelling. Antecedent Rainfall Ratio: This is defined as the total monthly rainfall for the current and previous months prior to laying the slab, divided by twice the average monthly rate measured for the period. The intent of this ratio is to give a relative measure of ground moisture conditions at the time the slab is placed. Thus, if a slab is placed at the end of a wet period, the slab shall be expected to experience some loss of support around the perimeter as the wet soil begins to dry out and shrink. The opposite effect could be anticipated if the slab is placed at the end of an extended dry period; as the wet season occurs, uplift around the perimeter may occur as the soil at the edge of the slab gains in moisture content. Age of Slab: The length of time since the slab was cast provides an indication of the type of swelling the soil profile may have beneath the slab. Initial Moisture Condition and Moisture Variation: A volume change in an expansive soil mass is the result of increases or decreases in water content. The initial moisture content influences the swell and shrink potential of a soil. However, moisture content alone is useless as an indicator or predictor of shrink -swell potential. The relationship between moisture content and other soil characteristics, such as the Plastic Limit and Liquid Limit, must also be known. If the moisture content is below or near the Plastic Limit, the soils may have a high potential to swell. Expansive soils with Liquidity Index in the range of 0.20 to 0.40 tend to experience little additional swell. The availability of water in an expansive soil profile is influenced by many environmental and manmade factors. Generally, the upper few feet of the profile are subjected to the widest ranges of moisture variation, and are the least restrained from movement by overburden. This upper stratum of the profile is referred to as the active zone. Moisture variation in the active zone of a natural soil profile is affected by climatic cycles at the surface and fluctuating groundwater levels at the lower moisture boundary. The superficial boundary moisture conditions are changed by placing a barrier, such as a building floor slab or pavement, between the soil and atmospheric environment. Other causes of moisture variation result from altered drainage conditions or manmade sources of water, such as irrigation or leaky plumbing. The latter factors are difficult to quantify and incorporate into the analysis but shall be controlled to the extent possible for each situation. For example, proper 2 LIQUIDITY INDEX— NATURAL WATER CONTENT —PLASTIC LIMIT LIQUID LIMIT — PLASTIC LIMIT Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 7 drainage and attention to landscaping are simple means of minimizing moisture fluctuations near structures and shall always be taken into consideration. Manmade Conditions That Can Be Altered: There are a number of factors that can influence whether a soil might shrink or swell and the magnitude of this movement. For the most part, the owner and/or designer have some control over whether these factors can be avoided, and if not avoided, the degree to which these factors may influence the shrink -swell process. Lot Drainage: How a lot is graded affects the accumulation of surface water around the slab. Most builders are aware of the importance of grading the soil away from the structure so that rainwater does not collect and pond adjacent to the foundation. If allowed to accumulate next to the foundation, water may infiltrate the expansive soils underlying the foundation, which could cause the foundation to settle. Similarly, runoff from surface water drainage patterns and swales must not collect adjacent to the foundation. Tonouaphy: As it swells, soil heaves perpendicularly to the ground surface or slope, but as it shrinks, it recedes in the direction of gravity and gradually moves downslope in a sawtooth fashion over a number of shrink -swell cycles. In addition to this shrink -swell influence, soil will exhibit viscoelastic properties and creep downhill under the steady influence of the weight of the soil. Therefore, to avoid a structure constructed on this slope from moving downhill with the soil, it must be designed to compensate for this lateral soil influence. Pre -Construction Vegetation: A large amount of vegetation, especially large trees, on a site prior to construction may have desiccation at the site. Constructing over a desiccated soil can produce some dramatic instances of heave and associated structural distress and damage as it becomes wet. Post -Construction Vegetation: The type, amount, and location of vegetation that has grown since construction can cause localized desiccation. Planting trees or large shrubs near a building can result in the loss of foundation support as the vegetation robs moisture from the foundation soil. Conversely, the opposite effect can occur ifflowerbeds or shrubs are planted next to the foundation and these beds are kept well -watered or flooded. This practice can result in swelling of the soil around the perimeter where the soil remains wet. Summation: It is beyond the scope of this investigation to do more than point out the factors that may influence the amount and type of swell a slab -on -grade foundation may be subjected to during its lifetime. The design engineer must be aware of these factors in developing his design, using his engineering experience and judgment as a guide. Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 8 7.0 DESIGN ENGINEERING ANALYSIS Foundation Design Considerations: Review of the boring and test data indicates that the factors presented on the following page will affect the foundation design and construction at this site: 1) The site is underlain by subsoils of low expansive potential at shallow depths. Structures supported at shallow depths will be subjected to potential vertical movements on the order of 1-2 inches. 2) The strengths of the underlying soils are adequate to support shallow or deep foundations. 3) Groundwater was encountered in our borings at the time of the subsurface exploration phase at a depth of 10 feet below existing grade on boring Bl. Structural Information: Based on the information provided, it is understood that the proposed structure will be a one to two story residence. These structures are expected to create moderately low loads to be carried by the foundation systems. These structures will utilize wood frame construction and brick or stucco exterior walls. It is assumed that the maximum column loads will not exceed 5 kips, while maximum exterior wall loading will be in the range of one kip per foot. Vertical Movements: The potential vertical heave for slab -on grade construction at the location has been estimated utilizing the liquid limits, plasticity indices, and in-situ moisture contents for soils in the seasonally active zone, estimated to be about twenty to twenty-five feet in the project area The estimated potential vertical heave value provided is based on the proposed floor system applying a sustained surcharge load of approximately one pound per square inch on the subgrade materials. Potential vertical movements on the order of 1-2 inches may be anticipated for average soil moisture conditions. The finish grade elevation was assumed to be '/2 to one foot above the existing grade level. Select structural fill shall be used to raise the elevation by'/2 to one foot. If the existing grade has to be raised to attain the finish grade elevation, select fill shall be placed, compacted and tested for compaction compliance by Terradyne 8.0 FOUNDATION RECOMMENDATIONS The type and depth of foundation suitable for a given structure primarily depends on several factors: the subsurface conditions, the function of the structure, the loads it may carry and the cost of the foundation. Additional considerations may include acceptable performance criteria set by the owner, architect, or structural designer with respect to vertical and differential movements that the structure can withstand without damage. Based on these conditions and the engineering design analysis spread or strip type footings bearing on undisturbed in-situ soils at a minimum depth of 3 feet below finished grade at the basement level can be used. Either a slab on grade or a structurally suspended slab can Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado be used. 8.1 Spread-Tvpe Footings 9 Spread or strip type footings at a minimum depth of three (3) feet below finished grade at the basement level bearing on 2 feet of select structural fill material that is moisture conditioned, placed and properly compacted can be used to support the structure. An allowable soil bearing pressure of 2,000 pounds per square foot is recommended for the design of spread or strip type footings at the basement level. In order to minimize the sensitivity of the structure to differential movement, the footings and walls should be reinforced to allow for a degree of load re -distribution should a localized zone of the supporting soils become saturated. Stem walls should either be positively separated from the floor slabs or reinforced to prevent cracking at the slab stem wall interface. Uplift resistance of shallow foundations formed in an open excavation should be taken as the weight of the foundation and soil above it. For design purposes, the uplift resistance should be based on total unit weights of 110 and 150 lbs. per cubic foot (pcf) for soil and concrete respectively. In areas where ground water is anticipated or in areas prone to flooding, the uplift resistance should be based on submerged unit weights of 57 and 87.5 pounds per cubic foot (pcf) for soil and concrete respectively. A factor of safety of 2 is recommended for sustained loading conditions, and 1.5 for transient loading conditions. 8.2 Foundation Construction Guidelines Significant moisture increase in the in-situ soils could create additional and/or excessive movements in the site. Accordingly, the site drainage and moisture protection provisions, recommended in this report are critical design considerations. Prior to placing concrete, all bearing surfaces must be cleared of all loose material. Disturbed material may only be re -compacted with guidance from, and after contacting Terradyne. To verify the soil conditions and soil bearing capacity, it is required that an open hole observation be performed. The entire excavation must be dug down to final grade prior to the observation. If potentially expansive clay, deleterious material, or other unsuitable conditions are found, additional over -excavation of some or the entire site may be required — replacing inadequate soils with acceptable materials. Revised foundation recommendations such as the use of drilled piers may also be required at that time. We recommend the foundation subgrade be inspected for adequacy before concrete placement. Ensure that the requirements contained herein are reflected in any construction plans developed for this site. Floor Slabs: Should the owner choose to use a structurally suspended slab, a positive void space of at least 6 inches shall be provided beneath the floor slab. The basement shall be designed with a Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 10 positive drainage flow so that water will not accumulate in the basement. Excavated on-site material that is free of deleterious material may be used to raise the grade in the basement area. This material shall be compacted to at least 95 percent of the ASTM D 698 maximum dry density at moisture contents that range from optimum to four (4) percent above the optimum, and the compacted soil should be tested by Terradyne to verify the moisture content and density for each compacted six (6) inch lift of material. 8.3 Slab -on -Grade Construction The Slab Performance Risk at this site is judged to be low. However, it must be understood, that changes in the water content of these soils may cause the soil to swell or shrink, which may cause movement or cracking of slabs. Potential vertical movement on the order of 1-2 inches is anticipated at the project site. Slabs should bear on proof -rolled and re -compacted materials. A proof -roll of the subgrade shall be observed by the geotechnical engineer's representative. They must not bear on gravel or other materials which may allow the migration of water below the slabs. If the on-site soils are not acceptable, it is preferable to bear slabs on non -expansive imported materials. This will minimize the transfer and retention of water below the slab. Materials with a Liquid Limit below 30 and a Plasticity Index between 10 and 15 are preferred. Slabs shall be isolated from foundation components by slip joints constructed to allow the independent movement of the slab. Slabs shall also be separated from any utility components by isolation joints. Mechanical equipment resting on slabs must be fitted with expandable/collapsible sections in order to allow movement of the slab without damage to the equipment or to the structure. Non-bearing partition walls must be constructed with a minimum of 2 inches of float to allow for movement of the slab without damaging any part of the structure. All doors shall be constructed with at least 1 -inch gap at floor level. It is the owner's responsibility to monitor and maintain all floats and gaps as necessary. If additional information on float is needed, please contact Terradyne. Slabs must be appropriately reinforced to resist the anticipated loads as well as the effects of the supporting soils. Floor slabs must also be scored in accordance with the American Concrete Institute (ACI) recommendations in order to control cracking of the slab due to shrinkage or other factors. These scores should be a maximum of 12 feet apart. 8.4 Utilities Utilities that project through slab -on -grade floors shall be designed with either some degree of flexibility or with sleeves in order to prevent damage to these lines should vertical movements occur. Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 11 8.5 Contraction, Control and/or Expansion Joints Contraction, control and/or expansion joints shall be designed and placed in various portions of the structure. Properly planned placement of these joints will assist in controlling the degree and location of material cracking that occurs due to soil movements, material shrinkage, thermal affects and other related structural conditions. 8.6 Lateral Earth Pressure Some retaining walls may be needed at this site. The equivalent fluid density values were evaluated for various backfill materials. These values are presented in Table No. 4. Table No. 4 Backfill Material Equivalent Fluid Density, PCF Active Condition At Rest Condition Passive Condition a. Crushed Limestone 40 60 530 b. Clean Sand 40 60 360 c. Select Fill (PI < 15) 65 85 265 These equivalent fluid densities do not include the effect of seepage pressures, surcharge loads such as construction equipment, vehicular loads or future storage near the walls. If a cantilever retaining wall can tilt forward to generate "active earth pressure" condition, the values under active condition shall be used. For rigid non -yielding walls which are part of the building, the values" at rest condition" shall be used. The compactive effort shall be controlled during backfill operations. Over compaction can produce lateral earth pressures in excess of at rest magnitudes. Compaction levels adjacent to below -grade walls shall be maintained between 95 and 98 percent of standard Proctor (ASTM D698) maximum dry density. The backfill behind the wall shall be drained properly. The simplest drainage system consists of a drain located near the bottom of the wall. The drain collects the water that enters the backfill and this may be disposed of through outlets along the base of the wall. To insure that the drains are not clogged by fine particles, they shall be surrounded by a granular filter. In spite of a well - constructed toe drain, substantial water pressure may develop behind the wall if the backfill consists of clays or silts. A more satisfactory drainage system, consisting of a back drain of 12 inches to 24 inches width gravel may be provided behind the wall to facilitate to drainage. The maximum toe pressure for wall footings founded a minimum depth of 36 inches into the clay soils shall not exceed 1,200 pounds per square foot. An adhesion value of 320 pounds per square foot should be used to check against sliding for wall footings bearing on clay. Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 12 9.0 CONSTRUCTION GUIDELINES 9.1 Construction Monitoring As Geotechnical Engineer of Record for this proiect, Terradvne, shall be involved in monitoring the foundation installation and earthwork activities. The performance of anv foundation system is not only dependent on the foundation design, but is strongly influenced by the quality of construction. Prior to construction, please contact our office so that a Foundation and Earthwork Monitoring Plan can be incorporated into the Proiect Quality Control Program. 9.2 Site Preparation In any areas where soil -supported floor slabs or pavement are to be constructed, vegetation and all loose or organic material shall be stripped and removed from the site. Subsequent to stripping operations, the subgrade shall be proofrolled to identify soft zones. Any soft zone detected shall be removed to afirm subgrade soils and replaced with compacted suitable soils to reach subgrade level. Upon the acceptance of proofrolling operations the subgrade shall be scarified to a minimum depth of 8 inches, moisture conditioned and compacted to a 95 percent of maximum dry density as determined by ASTM D 698, between optimum and 4 percentage points above of optimum moisture content The exposed subgrade shall not be allowed to dry out prior to placing structural fill. Select fill material used at this site shall be clayey sand (SC), lean clay with gravel (CL) or clayey gravel (GC) with maximum liquid limit of 35 percent and plasticity index (Pl) between 5 and 20. The fill shall be compacted to at least 95 percent of the maximum dry density as determined by ASTM D 698, within f 2 percentage points of optimum moisture content 9.3 Drainage Groundwater seepage was encountered in our boring during drilling operations. However, minor groundwater seepage may be encountered within the proposed building foundation and grading excavations at the time of construction, especially after periods of heavy precipitation. Small quantities of seepage may be removed by conventional sump and pump methods of dewatering. 9.4 Temporary Drainage Measures Temporary drainage provisions shall be established to minimize water runoff into construction areas. If standing water does accumulate, it shall be removed by pumping as soon as possible. Adequate protection against sloughing of soils shall be provided for workers and inspectors entering the excavations. This protection shall meet OSHA and other applicable building codes. 9.5 Groundwater In areas where significant cuts (2 -feet or more) are made to establish final grades for building pads, attention shall be given to possible seasonal water seepage that could occur through natural cracks and fissures in the newly exposed stratigraphy. Subsurface drains may be required to intercept Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 13 seasonal groundwater seepage. The need for these, or other dewatering devices, on building pads shall be carefully addressed during construction. Our office could be contacted to visually inspect final pads to evaluate the need for such drains. Groundwater seepage may occur several years after construction if the rainfall rate or drainage changes in the vicinity of the project site. If seepage runoff occurs towards the building, an engineer shall be contacted to evaluate its' effect and determine whether French drains are required at the location. 9.6 Control Testing and Field Observation Subgrade preparation and select structural fill placement shall be monitored by the project geotechnical engineer or his representative. As a guideline, at least one in-place density test shall be performed for each 2,500 square feet of compacted surface lift. A minimum of two density tests shall be performed on the subgrade or per lift of compaction. Any areas not meeting the required compaction shall be re -compacted and retested until compliance is met. 9.7 Earthwork and Foundation Acceptance Exposure to the environment may weaken the soils at the foundation bearing level if the excavation remains open for long periods of time. Therefore, it is recommended that all foundation excavations be extended to final grade and the footings constructed as soon as possible to minimize potential damage to bearing soils. The foundation bearing level shall be free of loose soil, ponded water or debris sand, and shall be inspected and approved by the geotechnical engineer or his representative prior to concreting. Foundation concrete shall not be placed on soils that have been disturbed by rainfall or seepage. If the bearing soils are softened by surface water intrusion during exposure or by desiccation, the unsuitable soils must be removed from the foundation excavation and replaced prior to placement of concrete. Subgrade preparation and fill placement operations shall be monitored by the geotechnical engineer or his representative. As a guideline, at least one in-place density test shall be performed for each 2,500 square feet of compacted surface lift. Any areas not meeting the required compaction shall be recompacted and retested until compliance is met. 10.0 DRAINAGE AND MAINTENANCE Final drainage is important for the performance of the proposed structures and pavement. Landscaping, plumbing, and downspout drainage is also important It is vital that all roof drainage be transported away from the building so that water does not pond around it, which can result in a soil Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, neatRidze. Colorado 14 volume change underneath the building. Plumbing leaks shall be repaired as soon as possible in order to minimize the magnitude of a moisture change under the slab. Large trees and shrubs shall not be planted in the immediate vicinity of the structures, since root systems can cause a substantial reduction in soil volume in the vicinity of the trees during dry periods. Adequate drainage shall be provided to reduce seasonal variations in moisture content of foundation soils. All pavement and sidewalks within 10 -feet of the structures shall be sloped away from the structures to prevent ponding of water around the foundations. Final grades within 10 -feet of the structure shall be adjusted to slope away from structures preferably at a minimum slope of 3 percent. Maintaining positive surface drainage throughout the life of the structure is essential. In areas with pavement or sidewalks adjacent to the new structure, a positive seal must be provided and maintained between the structures and the pavement or sidewalk to minimize seepage of water into the underlying supporting soils. Post -construction movement of pavement and flat -work is not uncommon. Maximum grades practical shall be used for paving and flatwork to prevent areas where water can pond. In addition, allowances in final grades shall take into consideration post construction movement of flatwork, particularly if such movement would be critical. Normal maintenance shall include inspection of all joints in paving and sidewalks, etc. as well as re -sealing where necessary. There are several factors related to civil and architectural design and/or maintenance that can significantly affect future movements of the foundation and floor slab systems. 1. Where positive surface drainage cannot be achieved by grading the ground surface adjacent to the buildings, a complete system of gutters and downspouts shall carry runoff water a minimum of 10 -feet from the completed structures. 2. Planters located adjacent to the structures shall preferably be self-contained. Sprinkler mains shall be located a minimum of five feet from the building line. 3. Planter box structures placed adjacent to the building shall be provided with a means to assure concentrations of water do not infiltrate the subsoils stratigraphy. 4. Large trees and shrubs shall not be planted closer to the foundations than a horizontal distance equal to roughly their mature height due to their significant moisture demand upon maturing. 5. Moisture conditions shall be maintained "constant" around the edge of the slabs. Ponding of water in planters, in unpaved areas, and around joints in paving and sidewalks can cause slab movements beyond those predicted in this report. Terradyne Engineering, Inc. C201018-5 Proposed Residence at 3273 Robb St, WheatRidge, Colorado 15 6. Roof drains shall discharge on pavement or be extended away from the structures. Ideally, roof drains shall discharge to storm sewers by closed pipe. Trench backfill for utilities shall be properly placed and compacted, as outlined in this report, and in accordance with the requirements of local City, County and/or State Standards. Since granular bedding backfill is used for most utility lines, the backfilled trench shall be prevented from becoming a conduit and allowing an access for surface or subsurface water to travel toward the new structures. Concrete cut-off collars or clay plugs shall be provided where utility lines cross building lines to prevent water from traveling in the trench backfill and entering beneath the structures. The potential vertical heave values estimated and stated under "Vertical Movements" are based on the provision that positive drainage shall be maintained to divert water away from the building and adjacent pavement. If this drainage is not maintained, the wetted front may occur below the assumed fifteen feet depth, and the resulting vertical heave may be 2 to 3 times greater than the stated values shown in this report. Utility leaks may also cause similar high movements to occur. 11.0 LIMITATIONS The analysis and recommendations submitted in this report are based upon the data obtained from the one (1) boring drilled at the site. This report may not reflect the exact variations of the soil conditions across the site. The nature and extent of variations across the site may not become evident until construction commences. If variations appear evident, it will be necessary to re- evaluate our recommendations after performing on-site observations and tests to establish the engineering significance of any variations. The project geotechnical engineer should review the final plan for the proposed building so that he may determine if changes in the foundation recommendations are required. The project geotechnical engineer declares that the findings, recommendations or professional advice contained herein have been made and this report prepared in accordance with generally accepted professional engineering practice in the fields of geotechnical engineering and engineering geology. No other warranties are implied or expressed. This report is valid until site conditions change due to disturbance (cut and fill grading) or changes to nearby drainage conditions or for 3 years from the date of this report, whichever occurs first. Beyond this expiration date, Terradyne shall not accept any liability associated with the engineering recommendations in the report, particularly if the site conditions have changed. If this report is desired for use for design purposes beyond this expiration date, we highly recommend drilling additional borings so that we can verify the subsurface conditions and validate the recommendations in this report.
