To the best of my professional knowledge, belief and opinion, the work was performed in substantial compliance with the applicable city standards. specifications and details. The project was constructed in substantial compliance with the approved drainage report and plans. Due to construction tolerances. the retaining wall surrounding the detention pond on the north and west side was built approximately 4 (four) inches short.

City of Wheat Ridge Planning and Development Department Memorandum TO: Kim Harrold Randy Busing f\[.L. /"tA. \/ lI../'ll (rP FROM: Mary Austin, Planner '1'\ ,A . SUBJECT: Building Permit Application for 4420 Allison St. DATE: March 28, 2000 The application and site plan for a building permit has been reviewed for compliance with the City's Code of Laws. Based on that review, I have the following comments: The zoning for the site listed on the site plan is not correct. The correct zone district is C-I, not PID, The building height needs to be indicated on the elevations. The height of a building is measured from the average elevation of the finished grade to the mean height level between eaves and the ridge of the gable, As defined in the Wheat Ridge Code of Laws, each 12 feet of a non-residential building is considered a story, Therefore, the proposed building is considered as a 2-story building for purpose of regulations, A 5 feet per story minimum side yard setback is required unless the structure is constru~ed of non-flammable or masonry material in accordance with the . :\ building code. It\\\.,,,OI-. ~ --\f""* L..e..~\....'-I~ 'S\ - ~ec" I\c~~ ott-..r \.L..a" - ';;lDe.) The required minimuk rear yard setback in the C-1 district is 10 feet for the first story plus an additional 5 feet for each additional story. The proposed building does not meet this rear yard setback requirement. A 15 foot sight triangle must be maintained at the driveway entrance. Within this sight triangle, the area between 42 inches and 84 inches must be maintained free and clear of obstruction. The proposed plan shows street trees within this sight triangle The side yard (north side) abuts a residential zone. Therefore. a 5 feet per story landscape buffer plus a 6 foot high solid decorative wall or fence is required. This landscape buffer should include sod or ground cover and trees and/or shrubs. Additional information is needed regarding plans for the "area to remain undisturbed". The landscaping plan cannot be reviewed until future plans for the area are known. OJ.?- ,/g. Parking requirements listed on the site plan are incorrect. Requirements for office/warehouse are as follows: I space per 600 square feet of floor area devoted to warehouse; I space per 300 square feet of floor area for retail, wholesale or office area. The floor are is defined as the gross floor area excepting the area used for restrooms. ,9, The combined use of office warehouse is subject to the following limitation: maximum of 75% of building area devoted to warehouse use and a minimum of25% of area devoted to office, retail or wholesale use. The proposed does exceeds the 75 percentage limitation for the warehouse area, ./ 10. Any proposed lighting needs to be shown on the site plan and must meet the requirements of Section 26-30 (S), Exterior Lighting Standards of the Wheat Ridge Code of Laws. 'W,,"'- L/11, Any signage for the site will require application for a sign permit and must meet the requirements of Article IV, Sign Code of the Wheat Ridge Code of Laws. 02. A pre-fabricated metal building with no architectural ornamentation is being proposed. Although the City of Wheat Ridge has no architectural design standards for buildings constructed in standard zone districts (non PUD's), we would ask that the owner consider applying some architectural relief. This architecture would be especially important on the west side facing Allison St., and on the north and east elevations which are adjacent to low density residential. This architectural relief could be in the way of brick wainscoting or vertical plantings adjacent to these elevations, We would be willing to discuss relief opportunities with you. -S ~"v~ q>t~ This concludes the comments as related to the zoning regulations. Be advised that there may be additional requirements from the City's Building Department and the Public Works Department. ~ - % lr"40L" " t~~- / /' ' >~2-/_:.~..'

Table 1 .. Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge. Colorado CONCLUSIONS The subsurface conditions encountered in the test holes drilled within the proposed building limits generally consisted of a thin topsoil veneer over approximately 7 to 8 feet of natural sand, Below the natural sand in Test Hole I, native sandy clay was encountered extending to a depth of approximately 13 feet. In Test Hole 2. sand and gravel was encountered below the sand a depth of 8 feet extending to a depth of approximately 13 feet. Below the native overburden materials. claystone bedrock was encountered. The claystone bedrock extended to the termination' depth of our test holes at approximately 20 to 21 feet below the test hole surface elevation. Free groundwater was encountered in Test Hole 2 at the time of drilling at a depth of approximately 8 feet. In Test Hole I, free groundwater was not encountered at the time of drilling due to the cohesive nature of the materials. however, we anticipate that over time the groundwater levels would stabilize to near the groundwater elevation observed in Test Hole 2, Considering the subsurface conditions encountered in the test holes and the nature of the proposed construction, we believe the proposed building may be supported by spread footings placed on the undisturbed natural sands or properly compacted non-expansive granular fill material. The footings may be designed for a maximum allowable bearing capacity of 1,250 pounds per square foot (pst). Given the variability in the foundation subgrade penetration resistance values. it appears that isolated areas of soft foundation soils may be encountered. These areas will require overexcavation and replacement of between 18 and 24 inches of material in a moisture-density controlled manner. Additional geotechnical design and construction considerations relating to the proposed building are presented herein. PURPOSE AND SCOPE OF STUDY .. This report presents the results of the geotechnical exploration performed for the proposed building located just to the west of Rocky Mountain Battery in the northwest corner of the intersection of Allison Street and 44th Avenue (4420 Allison Street), in Wheat Ridge, Colorado. The purpose of the subsurface exploration was to obtain subsurface soil and groundwater information for use by our client for the design of foundations and pavements, and the preparation of plans and specifications for construction of the proposed expansion. The project site is shown in Figure 1. Job No. 99-0215 GROUND Enginee.-ing Consultants. Inc. Page 1 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado A field exploration program was conducted to obtain information on subsurface conditions. Material samples obtained during the subsurface exploration were tested in the laboratory to provide data on the classification and engineering characteristics of the on-site soils, The results of the field and laboratory testing are presented herein. This report has been prepared to summarize the data obtained and to present our conclusions and recommendations based on the nature of the proposed addition and the subsurface conditions encountered. Geotechnical design parameters and a discussion of geotechnical engineering considerations related to construction are included. PROPOSED CONSTRUCTION We understand that the proposed work will consist of the construction of a single-story, wood or metal frame warehouse/shop building with no below grade level. The proposed building will be approximately 50 feet by 100 feet in plan dimension, Based on the existing site grades, it appears that site grading consisting of generally less than I to I Yz feet may be required. We have assumed the building foundation loads will be light to relatively moderate. typical of construction of this size, If loadings or conditions are significantly different from those described above, we should be notified to reevaluate the recommendations contained in this report, SITE CONDITIONS At the time of our field exploration. the proposed site consisted of an undeveloped vegetated field with native grasses, weeds, and occasional deciduous trees, The proposed site was generally flat with less than approximately I-foot of elevation change across the proposed building pad limits. The site was bordered to the east by an existing commercial building, to the north by residential property, to the west by Allison Street, and to the south by Rocky Mountain Battery. Based upon conversations with the client, it is our understanding that the property located to the immediate south previously existed as a service station, According to Mr, Harrold, all underground storage tanks associated with the station have been moved, FIELD EXPLORATION The field exploration for the project was conducted on July 9,1999. A total of two (2) test holes were drilled at the approximate locations indicated on Figure I to explore subsurfape conditions, and obtain Job No. 99-0215 . GROUND Engineering Consultants, Inc. Page 2 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado samples for laboratory testing. The test holes were advanced into the natural overburden soils with 4- inch diameter continuous flight power augers. The test holes were logged by a representative of GROUND Engineering Consultants, Inc. Samples of the subsurface materials were taken with a 2-inch J.D. California liner sampler and disturbed samples were obtained from the auger flight cuttings. The California sampler was driven into the various strata with blows from a 140-pound hammer falling 30 inches. The California liner test is similar to the standard penetration test described by ASTM Method D-1586. Penetration resistance values, when properly evaluated, indicate the relative density or consistency ofthe soils. Dep~s at which the samples were taken and the penetration resistance values are shown on the logs of the exploratory holes in Figure 2. The explanatory legend and notes for the test hole logs are presented in Figure 3. LABORATORY TESTING Samples obtained from our exploratory holes were examined and classified in the laboratory by the project engineer, Laboratory testing included standard property tests such as natural moisture contents; dry unit weights, grain size analyses" and liquid and plastic limits. In addition, swell-consolidation testing was performed on a selected sample obtained from our test holes to determine the volume change potential of the material with changes in moisture content. The results of our swell-consolidation testing are presented in Figure 4. Results ofthe laboratory-testing program are summarized on Table I. The laboratory testing was conducted in general accordance with' applicable ASTM specifications. SUBSURFACE CONDITIONS The subsurface conditions encountered in the test holes drilled within the proposed building limits generally consisted of a thin topsoil veneer over approximately 7 to 8 feet of natural sand, Below the natural sand in Test Hole I, native sandy clay was encountered extending to Ii depth of approximately 13 .. feet, In Test Hole 2. sand and gravel was encountered below a depth of 8 feet extending to a depth of approximately 13 feet. Below the native materials, claystone bedrock was encountered. These materials extended to the termination depth of our test holes at approximately 20 to 21 feet below the test hole surface elevation. Natural sand was encountered just below the topsoil veneer in our test holes, The sand was generally silty and fine to occasionally coarse grained, non to low plastic, loose to medium dense, dry to moist, and brown in color. Job No. 99-0215 GROUND Engineering Consultants, Inc. Page 3 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado Natural sand and gravel was encountered below the natural sand in Test Hole 2. The sand and gravel was generally fine to coarse grained with occasional cobbles. non to low plastic. dense, wet, and gray in color. Natural clay was encountered below the sand in Test Hole I. The clay was generally sandy, fine to occasionally medium and coarse grained, low plastic. stiff, and gray in color, Claystone bedrock was generally encountered below the natural overburden materials. These materials were generally fine grained, medium to highly plastic, hard to very hard, slightly moist, and brown to gray in color with occasional iron staining. Free groundwater was encountered in Test Hole 2 at the time of drilling at a depth of approximately 8 feet. In Test Hole I, free groundwater was not encountered at the time of drilling due to the cohesive nature of the materials, however, we anticipate that over time the groundwater levels would stabilize to near the groundwater elevation observed in Test Hole 2. Groundwater levels should be expected to fluctuate seasonally and annually with changes in precipitation, surface run-off. site grading, and landscape irrigation. It should be noted that varying degrees of apparent hydrocarbon contamination were observed in the soiVgroundwater during drilling operations. The source and type of the contamination was not a part of the scope of this report. SITE GRADING All fill material used inside the proposed building addition limits should be a nonexpansive granular soil. The fill should be placed in 8-inch loose lifts and should be compacted to at least 95 percent of the maximum modified Proctor density (ASTM 0-1557) within 2 percent of the optimum moisture content, Fill should not contain concentrations of organic matter or other deleterious substances. All fill materials should be tested and approved by GROUND prior to placement. Site grading should be planned to achieve positive drainage away from all structures and to prevent water from ponding in paved areas. Job No. 99-0215 GROUND Engineering Consultants, Inc. Page 4 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado FOUNDATION RECOMMENDATIONS Swelling materials were encountered at this site, However, the results of our swell tests suggest the overburden materials tested. generally exhibit low swelling characteristics, and the bedrock materials were encountered at depths of approximately 10 feet below the proposed bottom of footing elevation. Therefore, considering the subsurface conditions encountered in the test holes, we believe the proposed building addition may be supported by spread footings placed on the undisturbed natural sand or on properly compacted filL The design and construction criteria presented below should be observed for a spread footing foundation system, The construction details should be considered when preparing project documents. (1) Footings placed on the undisturbed natural sand or properly compacted fill may be designed for a maximum allowable soil bearing pressure of 1,250 pounds per square foot (pst). (2) Spread footings placed on granular soils should have a minimum footing dimension of 12 inches, (3) Exterior footings should be provided with adequate soil cover above their bearing elevation for frost protection. It is common in the Denver metropolitan area to place footings at a bearing elevation of at least 3 feet below the exterior finish grades, Footings placed at this depth are generally considered have adequate cover with respect to frost protection. (4) The lateral resistance of spread footing foundations placed on undisturbed or properly compacted subgrade materials will be developed as the sliding resistance of the footing on the foundation materials. Sliding friction at the bottom of the footings can be taken as 0.4 times the vertical dead load. Compacted fill placed against the sides of the footings should be a nonel<pansive on-site granular material approved by GROUND. Fill should be placed in uniform lifts not exceeding 8 inches in a loose state, and compacted to at least 95 percent of the maximum modified Proctor density (ASTM 0-1557) within 2 percent of the optimum moisture content. (5) Continuous foundation walls should be reinforced top and bottom to span an unsupported length of at least 10 feet. (6) Areas ofloose or soft material encountered within the foundation excavations should be removed Job No. 99-0215 GROUND Engineering Consultants. Inc. Page 5 Proposed Commercial Shop Building- 4420 Allison Street Wheat Ridge. Colorado and the footings extended to bear on a suitable foundation bottom. It may be possible that the loose or soft material may be removed and replaced in uniform lifts not exceeding 8 inches in a loose state, If this option is considered acceptable based on on-site observations, the backfill should be compacted to at least 95 percent of the maximum modified Proctor density (ASTM D- 1557) within 2 percent of the optimum moisture content. The zone of removal and recompaction should occur in a slope downward from the edges of the footings at I (horizontal) to 1 (vertical). (7) AII footing areas should be compacted with a vibratory plate compactor prior to placement of concrete in order to redensify the upper materials that may become disturbed during excavation and placement of concrete forms. (8) Care should be taken when excavating the foundations to avoid disturbing the supporting materials. Hand excavation or careful backhoe soil removal may be required in excavating the last few inches, Even excessive foot traffic can disturb the footing excavation bottom. We . - recommend the use of a backhoe bucket without teeth be used in excavating the final several r inches of material from the footing excavation bottoms, (9) Although not anticipated, traffic should be limited over footing excavations to reduce the potential for pumping or deformation of the materials, Some dewatering may be required depending on precipitation and runoff conditions. (10) A representative of GROUND should observe all footing excavations pnor to concrete placement. FLOOR SLABS Fill placed beneath floor slabs should be nonexpansive granular material approved GROUND, Fill should be placed in 8-inch loose lifts and should be compacted to at least 95 'percent of the maximum modified Proctor density (ASTM D-1557) within 2 percent of the optimum moisture content. In fill areas, or in areas where natural materials will be used as floor slab support, the natural soils should be scarified to a depth of 8 inches and compacted to 95 percent of the maximum standard Proctor density (ASTM D-698) within 2 percent of the optimum moisture content prior to fill placement. (I) Floor slabs should be placed directly on the natural soils or site grading fill materials after they are processed as recommended above. Job No. 99-0215 GROUND Engineering Consultants. Inc. Page 6 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge. Colorado (2) Floor slabs should be separated from all bearing walls and columns with an expansion joint, which allows unrestrained vertical movement, (3) Interior partitions resting on floor slabs should be provided with a slip joint so that if the slabs move, the movement cannot be transmitted to the upper structure. This detail is also important for wallboards and doorframes. A slip joint, which will allow at least 2 inches of vertical movement, is recommended. (4) Floor slabs should be provided with control joints to reduce damage due to shrinkage cracking and should be adequately reinforced. We suggest that joints be provided on the order of 12 feet on centers, The actual joint spacing should be based on the slab reinforcement design. (5) All plumbing lines should be carefully tested before operation. Where plumbing lines enter through the floor. a positive bond break should be provided, Flexible connections allowing at least 2 inches of vertical movement should be provided for slab-bearing mechanical equipment, The precautions and recommendations itemized above will not prevent the potential for floor slab distress, however, these precautions will reduce the potential for damage. . SURFACE DRAINAGE I The following drainage precautions should be observed during construction and maintained at all times after the addition has been completed: (I) Excessive wetting or drying of the foundation excavations and underslab areas should be avoided during construction. (2) Exterior backfill should be moistened to within 2 percent of the optimum moisture content and should be compacted to at least 95 percent of the maximum modified Pr6ctor density (ASTM D- 1557). (3) The ground surface surrounding the exterior of the buildings should be sloped to drain away from the foundation in all directions, We recommend a minimum slope of 12 inches in the first I 0 feet. (4) Roof downspouts and drains should discharge well beyond the limits of all backfill. Job No. 99-0215 GROUND Engineering Consultants. Inc. Page 7 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado (5) Landscaping which requires excessive watering and lawn sprinkler heads should be located at least 10 feet from foundation walls, (6) Plastic membranes should not be used to cover the ground surface adjacent to foundation walls. LIMITATIONS This report has been prepared in accordance with generally accepted soil and foundation engineering practices in this area for use by the client in evaluating subsurface conditions at their proposed addition site, The conclusions and recommendations submitted in this report are based upon the data. obtained from the exploratory holes' drilled at the approximate locations indicated on the attached site plan. The nature and extent of variations between the exploratory holes may not become evident until excavation is performed, Ifduring construction, soil, bedrock, and groundwater conditions appear to be different from those described herein. this office should be advised at once so that a reevaluation of the . recommendations may be made. We recommend on-site observation or testing of the foundation excavations, floor slab bearing strata, site grading fill. foundation wall backfill and structural concrete by a representative of GROUND Engineering Consultants, Inc. Swelling soils occur on this site, These soils stable at their natural moisture content. but can shrink or swell with changes in moistUre. The behavior of swelling soils is not fully understood. The swell potential of any particular site can change erratically both in lateral and vertical extent. Moisture changes also occur erratically, resulting in conditions which cannot always be predicted. The recommendations presented in this report are based on the current state-of-the-art for foundations and floor slabs on swelling soils. The owner should be aware that there is a risk in construction on these types of soils. Performance of the building will depend on following the recommendations and in proper maintenance after construction is complete. As water is the main cause for volume change of these soils, Job No. 99-0215 GROUND Engineering Consultants. Inc. Page 8 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge. Colorado it is necessary that the changes in moisture content be kept to a minimum, Any distress noted in the buildings and pavements should be brought to the attention of a professional engineer, Sincerely, GROUND Engineering Consultants, Inc, fJi~~ Robert T.

Geotechnical Exploration Proposed Commercial Building 4420 Allison Street Wheat Ridge, Colorado Prepared for: Mr. Kim Harrold 7975 West 44th Avenue Wheat Ridge, Colorado 80033 Job Number 99-0215 July 16, 1999 GROUND ENGINEERING CONSULTRNTS PHONE (303) 289-19Wl FAX (:-Hl3) 289-1686 7393 Dahlia Street. Commerce City. CO 80022-1834 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado A field exploration program was conducted to obtain information on subsurface conditions. Material samples obtained during the subsurface exploration were tested in the laboratory to provide data on the classification and engineering characteristics of the on-site soils. The results of the field and laboratory testing are presented herein. This report has been prepared to summarize the data obtained and to present our conclusions and recommendations based on the nature of the proposed addition and the subsurface conditions encountered, Geotechnical design parameters and a discussion of geotechnical engineering considerations related to construction are included, PROPOSED CONSTRUCTION We understand that the proposed work will consist of the construction of a single-story, wood or metal frame warehouse/shop building with no below grade level. The proposed building will be approximately 50 feet by 100 feet in plan dimension. Based on the existing site grades, it appears that site grading consisting of generally less than 1 to 1 Y, feet may be required, We have assumed the building foundation loads will be light to relatively moderate. typical of construction of this size. If loadings or conditions are significantly different from those described above, we should be notified to reevaluate the recommendations contained in this report, SITE CONDITIONS At the time of our field exploration, the proposed site consisted of an undeveloped vegetated field with native grasses, weeds, and occasional deciduous trees. The proposed site was generally flat with less than approximately I-foot of elevation change across the proposed building pad limits. The site was bordered to the east by an existing commercial building, to the north by residential property, to the west by Allison Street, and to the south by Rocky Mountain Battery. Based upon conversations with the client, it is our understanding that the property located to the immediate south previously existed as a service station. Accordingto Mr, Harrold, all underground storage tanks associated with the station have been moved. FIELD EXPLORATION The field exploration for the project was conducted on July 9. 1999, A total of two (2) test holes were drilled at the approximate locations indicated on Figure I to explore subsurf~ce conditions. and obtain Job No. 99-0215 GROUND Engineering Consultants. Inc. Page 2 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado samples for laboratory testing. The test holes were advanced into the natural overburden soils with 4- inch diameter continuous flight power augers, The test holes were logged by a representative of GROUND Engineering Consultants, Inc, Samples of the subsurface materials were taken with a 2-inch LD. California liner sampler and disturbed samples were obtained from the auger flight cuttings, The California sampler was driven into the various strata with blows from a l40-pound hammer falling 30 inches. The California liner test is similar to lbe standard penetration test described by ASTM Method D-1586. Penetration resistance values, when properly evaluated, indicate the relative density or consistency of the soils. Dep~hs at which lbe samples were taken and the penetration resistance values are shown on the logs of the exploratory holes in Figure 2. The explanatory legend and notes for the test hole logs are presented in Figure 3, LABORATORY TESTING Samples obtained from our exploratory holes were examined and classified in the laboratory by lbe project engineer. Laboratory testing included standard property tests such as natural moisture contents, dry unit weights, grain size analyses" and liquid and plastic limits. In addition, swell-consolidation testing was performed on a selected sample obtained from our test holes to determine the volume change potential of lbe material with changes in moisture content. The results of our swell-consolidation testing are presented in Figure 4. Results of the laboratory-testing program are summarized on Table I. The laboratory testing was conducted in general accordance with' applicable ASTM specifications. SUBSURFACE CONDITIONS The subsurface conditions encountered in the test holes drilled wilbin the proposed building limits generally consisted of a thin topsoil veneer over approximately 7 to 8 feet of natural sand. Below the natural sand in Test Hole 1, native sandy clay was encountered extending to a depth of approximately 13 .. feet. In Test Hole 2, sand and gravel was encountered below a depth of 8 feet extending to a depth of approximately 13 feet, Below the native materials. claystone bedrock was encountered, These materials extended to the termination depth of our test holes at approximately 20 to 21 feet below the test hole surface elevation. Natural sand was encountered just below the topsoil veneer in our test holes. The sand was generally silty and fine to occasionally coarse grained. non to low plastic. loose to medium dense. dry to moist. and brown in color, Job No. 99-0215 GROUND Engineering Consultants. Inc. Page 3 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge. Colorado Natural sand and gravel was encountered below the natural sand in Test Hole 2. The sand and gravel was generally fine to coarse grained with occasional cobbles, non to low plastic, dense, wet, and gray in color. Natural clay was encountered below the sand in Test Role 1. The clay was generally sandy, fine to occasionally medium and coarse grained. low plastic, stiff, and gray in color. Claystone bedrock was generally encountered below the natural overburden materials. These materials were generally fine grained, medium to highly plastic, hard to very hard, slightly moist, and brown to gray in color with occasional iron staining, Free groundwater was encountered in Test Hole 2 at the time of drilling at a depth of approximately 8 feet. In Test Hole I, free groundwater was not encountered at the time of drilling due to the cohesive nature of the materials, however, we anticipate that over time the groundwater levels would stabilize to near the groundwater elevation observed in Test Hole 2, Groundwater levels should be expected to fluctuate seasonally and annually with changes in precipitation, surface run-off. site grading, and landscape irrigation. It should be noted that varying degrees of apparent hydrocarbon contamination were observed in the soil/groundwater during drilling operations. The source and type of the contamination was not a part of the scope of this report. SITE GRADING All fill material used inside the proposed building addition limits should be a nonexpansive granular soiL The fill should be placed in 8-inch loose lifts and should be compacted to at least 95 percent of the maximum modified Proctor density (ASTM 0-1557) within 2 percent of the optimum moisture content. Fill should not contain concentrations of organic matter or other deleterious subfunces. All fill materials should be tested and approved by GROUND prior to placement. Site grading should be planned to achieve positive drainage away from all structures and to prevent water from ponding in paved areas. Job No. 99-0215 GROUND Engineering Consultants. Inc. Page 4 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge. Colorado FOUNDATION RECOMMENDATIONS Swelling materials were encountered at this site. However, the results of our swell tests suggest the overburden materials tested. generally exhibit low swelling. characteristics. and the bedrock materials were encountered at depths of approximately 10 feet be10w the proposed bottom of footil'g elevation. Therefore, considering the subsurface conditions encountered in the test holes. we believe the proposed building addition may be supported by spread footings placed on the undisturbed natural sand or on properly compacted filL The design and construction criteria presented below should be observed for a spread footing foundation system. The construction details should be considered when preparing project documents, (I) Footings placed on the undisturbed natural sand or properly compacted fill may be designed for a maximum allowable soil bearing pressure of 1,250 pounds per square foot (pst), (2) Spread footings placed on granular soils should have a minimum footing dimension of 12 inches. (3) Exterior footings should be provided with adequate soil cover above their bearing elevation for frost protection. It is common in the Denver metropolitan area to place footings at a bearing elevation of at least 3 feet below the exterior finish grades. Footings placed at this depth are generally considered have adequate cover with respeCt to frost protection, (4) The lateral resistance of spread footing foundations placed on undisturbed or properly compacted subgrade materials will be developed as the sliding resistance of the footing on the foundation materials. Sliding friction at the bottom of the footings can be taken as 0.4 times the vertical dead load. Compacted fill placed against the sides of the footings should be a nonellpansive on-site granular material approved by GROUND. Fill should be placed in uniform lifts not exceeding 8 inches in a loose state, and compacted to at least 95 percent of the maximum modified Proctor density (ASTM D-1557) within 2 percent of the optimum moisture content. (5) Continuous foundation walls should be reinforced top and bottom to span an unsupported length of at least 10 feet. (6) Areas of loose Dr soft material encountered within the foundation excavations should be removed Job No. 99-0215 GROUND Engineering Consultants. Inc. Page 5 Proposed Commercial Shop Building- 4420 Allison Street Wheat Ridge, Colorado and the footings extended to bear on a suitable foundation bottom. It may be possible that the loose or soft material may be removed and replaced in uniform -lifts not exceeding 8 inches in a loose state. If this option is considered acceptable based on on-site observations, the backfill should be compacted to at least 95 percent of the ~maximum modified Proctor density (ASTM D- 1557) within 2 percent of the optimum moisture content. The zone of removal and recompaction should occur in a slope downward from the edges of the footings at I (horizontal) to I (vertical), (7) AU footing areas should be compacted with a vibratory plate compactor prior to placement of concrete in order to redensif'y the upper materials that may become disturbed during excavation and placement of concrete forms, (8) Care should be taken when excavating the foundations to avoid disturbing the supporting materials, Hand excavation or careful backhoe soil removal may be required in excavating the last few inches, Even excessive foot traffic can disturb the footing excavation bottom, We . - recommend the use of a backhoe bucket without teeth be used in excavating the final several .. inches of material from the footing excavation bottoms. (9) Although not anticipated, traffic should be limited over footing excavations to reduce the potential for pumping or deformation of the materials. Some dewatering may be required depending on precipitation and runoff conditions, (10) A representative of GROUND should observe all footing excavations prior to concrete placement. FLOOR SLABS Fill placed beneath floor slabs should be nonexpansive granular. material approved GROUND, Fill should be placed in 8-inch loose lifts and should be compacted to at least 95 'percent of the maximum IVodified Proctor density (ASTM D-1557) within 2 percent of the optimum moisture content. In fill areas, or in areas where natural materials will be used as floor slab support, the natural soils should be scarified to a depth of 8 inches and compacted to 95 percent of the maximum standard Proctor density (ASTM D-698) within 2 percent of the optimum moisture content prior to fill placement, (I) Floor slabs should be placed directly on the natural soils or site grading fill materials after they are processed as recommended above, Job No. 99-0215 GROUND Engineering Consultants, Inc. Page 6 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado (2) Floor slabs should be separated from all bearing walls and columns with an expansion joint, which allows unrestrained vertical movement. (3) Interior partitions resting on floor slabs should be provided with a slip joint so that if the slabs move, the movement cannot be transmitted to the upper structure, This detail is also important for wallboards and doorframes, A slip joint, which will allow at least 2 inches of vertical movement, is recommended, (4) Floor slabs should be provided with control joints to reduce damage due to shrinkage cracking ,and should be adequately reinforced. We suggest that joints be provided on the order of 12 feet on centers. The actual joint spacing should be based on the slab reinforcement design, (5) All plumbing lines should be carefully tested before operation. Where plumbing lines enter through the floor, a positive bond break should be provided. Flexible connections allowing at least 2 inches of vertical movement should be provided for slab-bearing mechanical equipment. The precautions and recommendations itemized above will not prevent the potential for floor slab distress, however, these precautions will reduce the potential for damage. . SURFACE DRAINAGE The following drainage precautions should be observed during construction and maintained at all times after the addition has been completed: (1) Excessive wetting or drying of the foundation excavations and underslab areas should be avoided during construction. (2) Exterior backfill should be moistened to within 2 percent of the optimum moisture content and should be compacted to at least 95 percent of the maximum modified Pfoctor density (ASTM D- 1557), (3) The ground surface surrounding the exterior of the buildings should be sloped to drain away from the foundation in all directions. We recommend a minimum slope of 12 inches in the first 10 feet, (4) Roof downspouts and drains should discharge well beyond the limits of all backfill. Job No. 99-0215 GROUND Engineering Consultants, Inc. Page 7 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado (5) Landscaping which requires excessive watering and lawn sprinkler heads should be located at least 10 feet from foundation walls. (6) Plastic membranes should not be used to cover the ground surface adjacent to foundation walls, LIMITATIONS This report has been prepared in accordance with generally accepted soil and foundation engineering practices in this area for use by the client in evaluating subsurface conditions at their proposed additipn site, The conclusions and recommendations submitted in this report are based upon the data. obtained from the exploratory holes' drilled at the approximate locations indicated on the attached site plan, The nature and extent of variations between the exploratory holes may not become evident until excavation is performed. If during construction, soil, bedrock, and groundwater conditions appear to be different from those described herein, this office should be advised at once so that a reevaluation of the ,recommendations may be made. We recommend on-site observation or testing of the foundation excavations, floor slab bearing strata, site grading fill. foundation wall backfill and structural concrete by a representative of GROUND Engineering Consultants, Inc. Swelling soils occur on this site. These soils stable at their natural moisture content, but can shrink or swell with changes in moisture. The behavior of swelling soils is not fully understood. The swell potential of any particular site can change erratically both in lateral and vertical extent. Moisture ) changes also occur erratically, resulting in conditions which cannot always be predicted. The recommendations presented in this report are based on the current state-of-the-art for foundations and floor slabs on swelling soils, The owner should be aware that there is a risk in construction on these types of soils. Performance of the building will depend on following the recommendations and in proper maintenance after construction is complete, As water is the main cause for volume change of these soils, .. Job No. 99-0215 GROUND Engineering Consultants,lnc. Page 8 Proposed Commercial Shop Building 4420 Allison Street Wheat Ridge, Colorado it is necessary that the changes in moisture content be kept to a minimum, Any distress noted in the buildings and pavements should be brought to the attention of a professional engineer, Sincerely, GROUND Engineering Consultants, Inc.
