Specifically, the HVAC loads calculations contained in this report are not intended to be used for the purposes of sizing and/or selecting HVAC equipment. The California Energy Commission approved computer program used to determine the heating and cooling loads presented in this report uses an ASHRAE method as mandated by the California Energy Commission, and is therefore very accurate. If the information given to the author of this report is accurate, and the building is built as per the plans given to the author, then the load calculations presented in the report can be assumed to be as accurate as anyone can expect. A mechanical contractor may use these calculations as a starting point in system sizing and selection. Final HVAC sizing and selection should be done by a licensed mechanical engineer or mechanical contractor. Many factors beyond the scope of this report .must be considered prior to final system selection and design, such as: exact equipment availability and selection, system controls and location of controls, system air distribution and cycling, Uniform Building Code requirements, Uniform Mechanical Code requirements, and many other standard design conventions as listed by the American Society of Heating, Refrigeration, and Air Conditioning Engineers (ASHRAE). Newton Energy and the author of these calculations therefore assume no liability for final equipment selection or final system design. After proper system design, and prior to any system purchase or installation, please inform us in writing of any changes which may alter the assumptions and calculations contained in this report.

Engineering Company, Limited Combined Soil and Geologic Engineering Investigation and Report for Proposed Stable and 5-Foot High Retaining Walls at #5 Buggy Whip Drive, Rolling Hills, California, dated March 11, 2012. 1- Dear Mr. and Mrs. Nguyen: In accordance with your authorization, we have completed the subject investigation for the proposed one-story house addition at the subject site. The work was performed within the terms 'of your authorization using the degree of care and skill ordinarily exercised under similar circumstances by geotechnical engineers practicing in this locality, and in accordance with generally accepted foundation engineering procedures. The investigation included review of past soil and geologic reports prepared by us in 2009 and 2012, excavation of one additional test trench T-3, specific field soil and bedrock logging, and engineering analyses summarized herein. In the opinion of the undersigned, the accompanying updated report has been substantiated by the available field and laboratory data, and presents the design information you requested. Introduction This additional investigation was made for the purpose of obtaining information on the subsurface soil and bedrock conditions in the area of the proposed house addition on which to base conclusions and recommendations for suitable foundation designs for the proposed house addition at the subject property. It is our understanding that the proposed structure is to consist of a one-story, light wood frame, residential building construction. The proposed house addition is to be located on the south side of the existing residence. Mr. and Mrs. Nguyen - 2 - February 21, 2013 In 2009, a soil investigation and report was performed by us for the house additions and house remodeling at the subject site. This report was reviewed and approved by the County of Los Angeles. The house additions and house remodeling had been constructed and final was issued by the County of Los Angeles in 2010. All foundations for support of the house additions and house remodeling were founded into firm bedrock. In 2012, a stable and four new retaining walls were proposed in the eastern descending slope area. A geotechnical report was prepared by us for the stable and the walls. This report has been reviewed and approved by the County of Los Angeles. Construction of the stable and new retaining walls is underway at the time of this writing. The vicinity map of the subject site is shown on Plate 1. The on -site topographic map is shown on Plate 2. This updated report is not intended as a bidding document, and any contractors reviewing this report should draw their own conclusions regarding required construction quantities and procedures. Field and Laboratory Investiaation On February 18, 2013, one additional exploratory hand -dug test trench. T-3, was excavated at the location as shown on the attached Plate 2. Cross section B-B', drawn through the area of the proposed house addition, is shown in Plate 3. The earth materials encountered were logged by us as shown in the attached Trench Logs presented in Plate 4. Intact soil samples were obtained from the precious geotechnical investigation. Samples were returned to our laboratory for determination of their in -situ moisture content and density, classification, direct shear, expansion index, chemical testing and other appropriate testing. The laboratory test results and test trenches for the precious investigation is attached in Appendix A. One test trench T-3 was excavated in the area of the proposed house addition. Blanket fill, approximately 2 feet thick, was encountered. The encountered fill consisted of dark brown and black, moist to very moist, moderately soft, silty clay and adobe clay with abundant bedrock fragments. Below the blanket fill, bedrock was •encountered. The bedrock, encountered at the depth of approximately 2 feet to the depth of the trench explored, consisted of a light brown, gray, and yellowish brown, moist, well -bedded, siliceous shale and diatomaceous shale interbedded. Bedrock outcrops were observed near the new retaining walls which are to be located on the east side of the proposed house addition. The retaining walls are under construction at the time of this wiring. Bedrock outcrops exposed on the cuts for the construction of the walls. T.I.N. ENGINEERING COMPANY GEOTECHNICAL • STRUCTURAL • ENVIRONMENTAL Mr. and Mrs. Nguyen - 3 - February 21, 2013 Locations of the observed bedrock outcrops are shown on Topographic Map, Plate 2. A dipping bedding condition was observed on the cuts. The observed bedrock bedding, shown on the test trench T-3, was striking North and South and dipping approximately 8 degrees to West. The encountered bedrock bedding was dipping into the slope which provides a favorable geologic condition for the proposed house addition. No groundwater was encountered, nor were any springs or seeps observed during the course of this investigation. However, it should be noted that fluctuations in the level of the ground water may occur due to variations in rainfall, temperature, and other factors not evident at the time of our study. Corrosion Potential Chemical laboratory tests were conducted on the existing soil materials obtained from the prior exploratory trenches during the field investigation in 2009 for evaluation of a potential of soil corrosion and the attach on concrete by sulfate soils. The testing results are re- presented below: SAMPLE LOCATION T-2 @ 3.0', BEDROCK General MIN. CHLORIDE SULFATE RESISTIVITY PH (PPM) (PPM) (OHM -CM) 7.70 280 < 100 18,200 Conclusions and Recommendations Based upon our evaluation of the site and soil conditions, the foregoing data and information, the following conclusions and recommendations are made. Construction of the proposed house addition is feasible from the standpoint of geotechnical engineering practice at the subject site, provided all recommendations and conditions made herein are incorporated into all design. The thickness of earth materials and the depths to foundation stratum indicated in this report are based on the data obtained from the exploratory trenches excavated in 2009 and 2013 and the observed bedrock outcrops. The actual thickness of earth materials and depths to foundation stratum between the exploratory trenches and the observed bedrock outcrops may vary from that indicated herein. The design and construction procedures should take this into account. 1. The proposed house addition, should be founded„ on spread footings penetrating intoflrrn bedrock as specified as below. The depth to the firm bedrock in the area of the proposed T.I.N. ENGINEERING COMPANY GEOTECHNICAL • STRUCTURAL • ENVIRONMENTAL Mr. and Mrs. Nguyen - 4 - February 21, 2013 house addition is estimated to be approximately 1 to 2 feet below the existing grade, although it may be deeper. 2. The east side of the proposed house addition is to be located near the top of the eastern g peolo ie condition encountered at the subject site, to a favorable, ' � �� g�.g the _foundation ' setback may be reduced. We recommend that the foundations of the descending slope. e. Due ry y e b .. at s __... of the f c ...„ —proposed- -- feet of the slope as shown_ on Section A -A , Plateo3t We estimate that the depth f the western foundations for the support of the proposed eastern addition may be-7 feet. 3. The existing house foundations may founded into fill. If the existing house foundations are'to be utilized for the support of the proposed house addition, underpinning the existing house foundations with new foundations -penetrating at least 12 inches into firm bedrock may be required. 4. The on -site bedrock was previously tested for sulfate content. Sulfate content over 150 ppm was not detected. It is recommended that type I or II cement should be utilized for this project. Spread Footina Foundations Spread footings founded into firm bedrock may be used for support of the proposed house addition. The following design criteria for new foundations are considered appropriate: Allowable Bearing Capacity 2,500 psf Minimum Embedment Below Lowest Adjacent Grade and into Firm Bedrock One -Story 12 inches Minimum Width of Spread Foundation: One -Story 15 inches All continuous footings should be reinforced with a minimum of four #4 steel bars, two placed near the top, and two placed near the bottom of the footings. Lateral Design Resistance to lateral loading may be provided by friction acting at the base of foundations and by passive earth pressure within firm bedrock. An allowable coefficient of friction of 0.40 may be used with the dead load forces. T.I.N. ENGINEERING COMPANY GEOTECHNICAL • STRUCTURAL. • ENVIRONMENTAL Mr. and Mrs. Nguyen 5 February 21, 2013 For spread footings in firm bedrock the allowable passive earth pressure may be computed as an equivalent fluid having a density of 600 pounds per square foot per foot with a maximum earth pressure of 9,000 pounds per square foot. When combining the passive and friction values for calculating the lateral resistance, the passive component shall be reduced by one third. The vertical and lateral bearing values indicated above are for the total of dead and all frequently applied live loads and may be increased by one-third for short duration loading which includes the effects of wind or seismic forces. Seismic Coefficients Bedrock was encountered at the subject site. The foundations of the proposed house addition and new deck are to be founded into firm bedrock. Therefore, the following seismic coefficients should be utilized for designs of the proposed structures at the subject site: • Site Latitude = 33.7599, Longitude =-118.3585 • Site Class: C • Site Coefficient, Fa = 1.0 • Site Coefficient, F„ =1.3 • Spectral Acceleration for Short Periods, Ss = 1.729 • Spectral Acceleration for a 1-Second Period, Si = 0.707 • Maximum Spectral Acceleration for Short Periods, SMs = FaSs = 1.729 • Maximum Spectral Acceleration for a 1-Second Period, SMi = F„S1 = 0.919 • Design Spectral Acceleration at Short Periods, Sns = 2/3 SMs = 1.153 • Design Spectral Acceleration at 1-Second Period, SDI = 2/3 Shin = 0.612 • Seismic Design Category: D Foundation Settlement Settlement of new foundation system is expected to occur on initial application of loading. The settlement is expected to be '/ to 3/ inch, depending upon final loads. Differential settlement is not expected to exceed 1/3 inch for a horizontal distance of 30 feet. It is possible that the differential settlement between the existing portion of the house and the new construction could exceed the value given above and this should be taken into account by the structural engineers and the contractor, who should exercise care and good construction practice during construction of the addition. T.I.N. ENGINEERING COMPANY GEOTECHNICAL • STRUCTURAL• ENVIRONMENTAL 1 1 Mr. and Mrs. Nguyen 6 February 21, 2013 Temnorary Construction Excavations Excavations will be required for the proposed construction. The excavation is expected to expose on -site soil and bedrock which are not suitable for vertical excavations over five feet. Portions of excavations over five feet should be trimmed to a 1:1 slope gradient. All excavations should be stabilized within 30 days of initial excavation. Water should not be allowed to pond on top of the excavation nor to flow toward it. No vehicular surcharge should be allowed within five feet of the top of cut. All safety provisions of Cal OSHA and other related statutory agencies should be adhered to, especially as related to support of adjacent structures. Temporary shoring should be designed for an active equivalent fluid pressure of 30 pounds per cubic foot. Temporary excavations during raining season are subject to potential hazards, such as caving, floods, erosion, raveling of the cuts and concentrated drainage. The potential damage from these hazards can be greatly reduced by maintenance of cuts and drainage facilities and erosion controls in the surrounding areas of the cuts. It is the responsibility of the owner or the project contractors to maintain the excavated areas and to improve any deficiencies found during raining season.

ENGINEERING COMPANY GEOTECHNICAL • STRUCTURAL • ENVIRONMENTAL Mr. and Mrs. Nguyen 7 February 21, 2013 Grading The General Earthwork Specifications, Appendix B, should be used in preparation of the grading plans and job specifications where engineered fills are used and constitute our definition of an engineered fill. We should review all documents prior to submittal for statutory permits or contracting in order to ascertain that the intents of our recommendations are conveyed. Drainage Control Control of soil moisture is essential for the long term performance of improvements, particularly those located on or near expansive soils. All roof and surface drainage should be conducted away from the development in engineered non -erosive devices to an on -site safe point of discharge. No site runoff drainage should be allowed to cross over the tops of slopes except in engineered non -erosive devices. Slabs and planted areas immediately adjacent to the dwelling or appurtenant structures should slope away from said structures to mitigate pooling of water. All slabs and planted areas should be sloped to drain to a safe point of collection. Slabs should have a minimum slope of one percent and planted areas a minimum of two percent. All roof drainage should be collected in eave gutters that discharge directly into engineered non -erosive drainage devices. All joints in slab and swales should be maintained sealed with an appropriate joint compound. Grading Ordinances.

We should review all documents prior to submittal for statutory permits or contracting in order to ascertain that the intent of our recommendations is conveyed. 1. The area to receive compacted fill shall be stripped of all vegetation, debris, existing fill, and soft or disturbed soils, The excavated areas shall be reviewed by the geotechnical engineer in the field prior to placing controlled, compacted fill.. 2. The exposed grade shall then be benched, appropriately graded, scarified to a depth of six inches, moistened to optimum moisture and recolnpacted to 90 percent of the maxilnuin density. 3. The excavated on -site materials are considered satisfactory for reuse in the engineered fill. Remove any organic trash or deleterious materials. Remove boulders larger than 6 inches. . Soil shall be spread evenly in layers not to exceed 4 inches while loose for compaction by wackers. Add water as required. Only approved compaction equipment shall be used. 5. The fill shall be compacted to at least 90 percent of the maximum laboratory density for the material used. The maximum density shall be determined by ASTM D 1557- 00. 6. Periodic on -site construction reviews and field tests shall be performed by the geotechnical engineer during grading to assist the contractor in obtaining the required degree of compaction and the proper moisture content. Where compaction is less than required, additional compactive effort should be made with adjustment of the moisture content, or the layer stripped out and replaced in thinner layer, as necessary, until a minimum of 90 percent relative compaction is obtained. The contractor shall call the soil engineer to test every two feet of vertical lift. 7. No fill soils shall be placed during unfavorable weather conditions. When work is interrupted by rains, fill operation shall not be resumed until the field tests by the soils engineer indicate that the moisture content and density of the fill are as previously specified.
