Addendum No.1 November 18, 2016 Report of Subsurface Exploration and Geotechnical Engineering Services 5 th Bay Ocean View Norfolk, Virginia G E T Project No: VB15-342G Project and Site Description The project site is located on 5 th Bay Street in the Ocean View section of the City of Norfolk, Virginia and is only slightly developed with 4 residences throughout the specified area. Elevations for the site area range from 4 to 9 MSL based on provided topographic plans. The proposed construction at this site will consist of building several single-family structures. Project specifications are unknown at this time but the structures are expected to be of CMU and structural steel construction. The maximum wall and column loads are not expected to exceed 1-1.5 klf and 50 kips, respectively. The finish grades are expected to coincide with current grades, thus cuts and fills are not expected to exceed 1 to 2 feet. New roadways, BMP facilities, and associated infrastructure will be constructed as well. If any of the noted information is incorrect or has changed, please inform G E T Solutions, Inc. so that we may amend the recommendations presented in this report, if appropriate. Purpose and Scope of Services The purpose of this study was to obtain information on the general subsurface conditions at the proposed project site. The subsurface conditions encountered were then evaluated with respect to the available project characteristics. In this regard, engineering assessments for the following items were formulated: 1. Determine pertinent information regarding groundwater and subsurface permeability conditions. (Installation of temporary groundwater monitoring well and infiltration testing). The scope of services did not include an environmental assessment for determining the presence or absence of wetlands or hazardous or toxic material in the soil, bedrock, surface water, groundwater or air, on or below or around this site. FIELD AND LABORATORY PROCEDURES Field Exploration In order to explore the general subsurface soil types and to aid in developing associated construction design parameters, the following field exploration program was performed at the site: A temporary groundwater monitoring well was installed at the INF-4 boring location for a groundwater level reading. Eleven (11) infiltration tests were performed at locations specified by the client. 1
Addendum No.1 November 18, 2016 Report of Subsurface Exploration and Geotechnical Engineering Services 5 th Bay Ocean View Norfolk, Virginia G E T Project No: VB15-342G One (1) monitoring well was installed to facilitate groundwater sampling. The monitoring well is constructed of 2-inch I.D., Schedule 40 PVC materials. Sections of 0.010-inch slotted screen were placed in the boreholes with casing threaded to the top. The top of the screen was positioned above the water level. An appropriately graded sand/gravel pack was placed around the screen and extended one to two feet above the top of the screen. A 1- to 2- foot bentonite seal was then placed above the sand/gravel pack and hydrated with potable water. The remainder of the borehole annular space was pumped full of a neat cement grout. The well was then fitted with a PVC slip cap. Eleven (11) infiltration tests were performed at locations specified by the client. A handauger was performed to a depth of 1 foot above the measured groundwater level. Infiltration testing was then conducted within the vadose zone utilizing a Precision Permeameter. The infiltration locations were established by the client and staked in the field by a representative of G E T Solutions, Inc. The approximate locations are shown on the attached Boring Location Plan (Appendix I) Laboratory Testing Representative portions of all soil samples collected during drilling were sealed in glass jars, labeled and transferred to our laboratory for classification and analysis. The soil classification was performed by a Project Geologist in accordance with ASTM D2488. A summary of the soil classification system is provided in Appendix II. Eleven (11) representative soil samples were selected and subjected to natural moisture and #200 sieve wash in order to corroborate the visual classification. These test results are presented on the Summary of Laboratory Results sheet (Appendix III). SITE AND SUBSURFACE CONDITIONS Site Geology The project site lies within a major physiographic province called the Atlantic Coastal Plain. Numerous transgressions and regressions of the Atlantic Ocean have deposited marine, lagoonal, and fluvial (stream lain) sediments. The regional geology is very complex, and generally consists of interbedded layers of varying mixtures of sands, silts and clays. Based on our review of existing geologic and soil boring data, the geologic stratigraphy encountered in our subsurface explorations generally consisted of marine deposited sands and clays. 2
Addendum No.1 November 18, 2016 Report of Subsurface Exploration and Geotechnical Engineering Services 5 th Bay Ocean View Norfolk, Virginia G E T Project No: VB15-342G Groundwater Information The groundwater level was recorded at the infiltration locations as observed through the relative wetness of the recovered soil samples during the testing operations. The initial groundwater table was generally determined to occur at an approximate depth of 2.5 to 3 feet below current grades at the infiltration locations at the time of our site reconnaissance. The boreholes were backfilled upon completion for safety considerations. As such, the reported groundwater level may not be indicative of the static groundwater level. In addition, groundwater readings were taken at the temporary groundwater monitoring well installed as well as an older well location from prior work. At the time of this reporting the groundwater wells remained in place for future monitoring. The groundwater information associated with the wells is displayed below in Table I and Appendix IV. Table I Groundwater Monitoring Well Readings Boring No. Initial Groundwater Reading (ft)* 24-hour Groundwater Reading (ft)* INF-4 3.0 2.5 **B-2 2.5 - * Depth below existing site grades **Existing well from prior project work. Groundwater conditions will vary with environmental variations and seasonal conditions, such as the frequency and magnitude of rainfall patterns, as well as man-made influences, such as existing swales, drainage ponds, underdrains and areas of covered soil (paved parking lots, side walks, etc.). In the project s area, seasonal groundwater fluctuations of 2 feet are common; however, greater fluctuations have been documented. We recommend that the contractor determine the actual groundwater table levels at the time of the construction to determine groundwater impact on the construction procedures, if necessary. EVALUATION AND RECOMMENDATIONS Our recommendations are based on the previously discussed project information, our interpretation of the soil test borings, our laboratory testing and our observations during our site reconnaissance. If the proposed construction should vary from what was described, we request the opportunity to review our recommendations and make any necessary changes. 3
Addendum No.1 November 18, 2016 Report of Subsurface Exploration and Geotechnical Engineering Services 5 th Bay Ocean View Norfolk, Virginia G E T Project No: VB15-342G Soil Permeability Eleven (11) infiltration tests were performed within specified locations and within vicinity of the temporary monitoring well location. A hand-auger was performed adjacent to the well or in specified locations to a depth of 1 foot above the estimated groundwater level or measured 24-hour groundwater level. The boreholes were prepared utilizing an auger to remove soil clippings from the base. Infiltration testing was then conducted within the vadose zone utilizing a Precision Permeameter and the following testing procedures. A support stand was assembled and placed adjacent to the borehole. This stand holds a calibrated reservoir (130 ml) and a cable used to raise and lower the water control unit (WCU). The WCU establishes a constant water head within the borehole during testing by use of a precision valve and float assembly. The WCU was attached to the flow reservoir with a 2-meter (6.6 foot) braided PVC hose and then lowered by cable into the borehole to the test depth elevation. As required by the Glover solution, the WCU was suspended above the bottom of the borehole at an elevation of approximately 5 times the borehole diameter. The shut-off valve was then opened allowing water to pass through the WCU to fill the borehole to the constant water level elevation. The absorption rate slowed as the soil voids became filled and an equilibrium developed as a wetting bulb developed around the borehole. Water was continuously added until the flow rate stabilized. The reservoir was then re-filled in order to begin testing. During testing, as the water drained into the borehole and surrounding soils, the water level within the calibrated reservoir was recorded as well as the elapsed time during each interval. The test was continued until relatively consistent flow rates were documented. During testing the quick release connections and shutoff valve were monitored to ensure that no leakage occurred. The flow rate (Q), height of the constant water level (H), and borehole diameter (D) were used to calculate Ks utilizing the Glover Solution. Based on the field testing and corroborated with laboratory testing results (published values compared to classification results), the hydraulic conductivity of the soils is listed on the following page in Table II and is presented on the Hydraulic Conductivity Worksheets (Appendix IV), included with this report. 4
