GLOTECHNICA L ENGINEERING Geotechnical Report For Proposed Apartment Building 33-37 Caroline Street Saratoga Springs, NY File No. 4458 Prepared For: Dempsey Development n,Ew�� Loud �� T CJ F q'' 0 15 Apri 2625 2615 PAGE STORE ROAD, CAMERON, NC 28326 0 518-369-9453 ■ F-MAIL: DGLGEOENG@GMAIL.COM INTRODUCTION: The subsurface investigation for the proposed Apartment Building, 33-37 Caroline Street, Saratoga Springs, New York has been completed. LaBella of Ballston Spa, New York has completed three (3) soil borings at the site. The logs of these borings, along with a location diagram, have been included in the appendix of this report. It is my understanding that the proposed construction will include a five -story building, with a lower level parking garage located approximately as indicated on the boring location diagram. The lower two levels will have a steel frame and reinforced concrete bearing -wall design. The upper four levels will have a woad frame design. The maximum column loadings were not available at the time this report was issued, but I have estimated they could range from 45C to 600 kips. Bearing wall loads will range from 6 to 8 kips per foot of wall. The settlement tolerances are normal. Settlement tolerances are considered to include up to 1 inch of total settlement and 3/4 inch of differential settlement between column locations. The lower parking garage floor slab will be established at approximately 10 feet below the existing grades at the site. The purpose of this report is to describe the investigation conducted and the results obtained; to analyze and interpret the data obtained; and to make recommendations for the design and construction of the feasible foundation types and earthworks for the project. The recommendations contained in this report are based on the information that was provided up to the date the report was completed. Any changes in the design of the project or changes to the recommendations provided in this report should be brought to my attention to determine if there needs to be any revision of the geotechnical recommendations. I am not responsible for any changes made to the recommendations provided in this report unless I have provided written approval of the changes. Additional boring(s) and pile testing will be required to provide final design recommendations. The scope of my services has been limited to coordinating the boring and laboratory investigation, analyzing the soils information, and providing a geotechnical report with preliminary foundation recommendations and seismic site classifications as per NYS Building Code. Environmental aspects of the project as well as grading and site design should be performed by qualified others. Design of any, piles, sheeting and shoring, underpinning and dewatering should be performed by qualified others. FIELD INVESTIGATION PROCEDURES: The borings were extended by means of 3.75 inch ID, hollow -stem augers, hollow steel casing and by using various cutting bits using circulating drilling fluid to remove the cuttings from the casing and by continuous sampling with a split -spoon sampler. Representative samples were obtained from the boring holes by means of the split -spoon sampling procedure performed in accor- dance with ASTM D 1586. The standard penetration values obtained from this procedure have been indicated on the soil boring logs. Soil samples obtained from these procedures were examined in the field, sealed in containers, and shipped to the laboratory for further examination, classification, and testing, as applicable. Representative samples of the boulder/cobble materials were obtained by means of the diamond -bit sampling procedure performed in accordance with ASTM D 2113. NQ2-size core barrels were used for this sampling procedure. During the investigation, water level readings were obtained at various times where water accumulated in the boring hole. The water level readings, along with an indication of the time of the reading relative to the boring procedure, have been indicated on the soil boring logs. LABORATORY INVESTIGATION: All samples were examined in the laboratory by the soil engineer and classified according to the Unified Soil Classification System. In this system, the soils are visually classified according to texture and plasticity. The appropriate group symbol is indicated on the soil boring logs. Samples exhibiting significant cohesion were tested with a calibrated, spring -loaded, penetrometer. This test is used to 3 estimate the unconfined compressive strength of the soil sample by measuring the soil's resistance to the penetration of the penetrometer needle. The results of these tests are listed on the boring logs. SITE CONDITIONS: I understand that the site has two existing buildings with the remaining areas being paved. The ground surface at the site varies in elevation between approximately 5 and 7 feet. I also understand that there is an adjacent building to the east that is within 3 feet of the property line that has a partial basement in one area and no basement in another portion. I understand that the existing building in the northeast corner of the site has a full basement that extends approximately 10 feet below the existing grades at the site. In addition I understand that there is a large diameter pipe the extends through the center portion of the site that is approximately 15 feet below the existing grade. This pipe is owned by the City of Saratoga Springs. And its condition is not known. SUBSURFACE CONDITIONS: The specific subsurface conditions encountered at each boring location are indicated on the individual soil boring logs. However, to aid in the evaluation of this data, I have prepared a generalized description of the soil conditions based on the boring data. Boring locations and amounts were limited due to existing structures. The borings encountered an upper layer of uncontrolled fill that extends to between approximately 4 and 10 below the existing grade at the site. This uncontrolled fill contains sand with varying amounts of silt, gravel, ash/cinders, brick and concrete. Below the uncontrolled fill in borings B-1 and B-3 is a layer of sand with clayey silt/silt and a trace to some peat. This layer is loose and extended to between approximately 11 and 12 feet below the existing ground surface. A layer of sand with silt was encountered under the uncontrolled fill in B-2. 4 Underlying the sand with clayey silt/silt and peat are layered silt and clay soils. These soils are loose/medium stiff to stiff and extended to the bottom of boring B-3 at 17 feet and to between approximately 38 and 40 feet in borings B-1 and B-2. Beneath the layered silt and clay soils are sand and clayey silt soils with varying amounts of gravel. Cobbles and boulders were encountered in these soils at between 57 and 75 feet below the existing ground surface. A boulder was cored between 57 and 60 feet in boring B-2. 'these soils are dense to very dense. Borings B-1 and B-2 were terminated at 63.3 and 75.0 feet below the existing ground surface because the driller was not able to advance the borings. No rock core was obtained and it is possible bedrock could be deeper than the borings extended. If the owner decides to use mini -piles that are. socketed into bedrock, I recommend that at least one additional boring with a 10 foot rock core be taken to better estimate. the depth to bedrock and the quality of the bedrock. In my experience bedrock in this area is typically limestone. GROUNDWATER CONDITIONS: Based on the groundwater levels observed during the boring investigation, the moisture condition of the samples recovered from the boring holes and coloration of the soil samples, I judge that the groundwater level was located below depth of 7 feet. Perched groundwater tables may occur at higher elevations in the soil profile due to groundwater being retained by layers or lenses of silt or clay soils. Some fluctuation in hydrostatic groundwater levels and perched water conditions should be anticipated with variations in the seasonal rainfall and surface runoff. It should be noted that the groundwater levels were obtained during the drilling procedure. Actual water levels may vary at the time of construction. Some groundwater could be encountered in soil layers labeled moist to wet on the boring logs. 5 ANALYSIS AND RECOMMENDATIONS: I understand that the final building design has not been completed, but the owner would like to have a basement parking garage that extends at least 10 feet below the existing grades at the site and that the proposed building footprint will extend to within approximately 3 feet of the existing property lines. I also understand that the lower two building levels will be constructed of steel and reinforced concrete, with the remaining upper levels having a wood frame design. The borings encountered an upper layer of uncontrolled fill soils and a layer of soils with peat to depths of between approximately 10 and 12 feet below the existing ground surface. Loose/medium stiff to stiff layered silt and clay soils were encountered below the uncontrolled fill/organic soils to a depth of between approximately 38 and 40 feet below the existing ground surface. Dense to very dense sand and clayey silt soils with gravel, cobbles and bounders was encountered below the layered silt and clay to the bottom of the borings at between approximately 63 and 75 feet below the existing ground surface. I understand there is also a large diameter pipe that extends approximately 15 feet below grade at the site and the condition is not known. Based on the boring results and my understanding the grading, estimated building loads and the existence of the pipe at the site, it is my opinion that the proposed building cannot be adequately supported on spread footing foundations because of settlements that would occur that could affect the pipe below. In my opinion if the pipe is shallow enough to replace the owner should consider it, provided the City approves. I recommend that the proposed building be supported by mini - piles that extend to bedrock or possibly helical piles that extend into the dense sand and clayey silt soils below 50 feet. The pile design should be performed by qualified others. I recommend that the owner perform a cost estimate with both options to determine which option may be the most cost effective. For the mini -pile estimate I would estimate that the piles would extend a minimum of 75 feet below the existing ground surface and then at least a 10 feet embedment in to bedrock. 6 Preliminarily a rock socket side friction of 100 psi could be used for design. Additional borings(s) would be required to more accurately determine the cost and side friction values if this option is chosen. For estimating purposes for the helical pile option. I would assume a minimum depth of 50 feet. Piles that extend deeper will have higher capacities.. For the estimate, depending on the depth that helical piles are advanced into denser soils, they could achieve capacities of between 20 and 30 kips per pile. Test piles should be installed to more accurately determine the design capacity. Either of these pile options should then be designed to support the entire building and garage floor slab utilizing pile caps and grade beams. The pile estimates are based on past experience and final design values will need to be determined with additional boring(s) and testing. Design of any sheeting and shoring, underpinning and dewatering should be performed by qualified others. I recommend that adjacent site be surveyed and monitored during construction to verify no damage is occurring to adjacent structures. Ground vibrations during the installation of any sheeting or shoring should also be monitored to verify that peak particle velocities do not exceed values that could cause damage to adjacent structures.. Site Work: I recommend that the existing pipe be replaced with a properly designed pipe if possible. The proposed construction areas should be cleared and grubbed and all organic topsoil and vegetation along with any uncon- trolled fill and debris.. The subgrade should be observed and probed by the soil engineer or qualified technician under the guidance of a soil engineer in place of proof rolling. Placement of a pad of crushed stone with geotextile will be required to improve the stability of the subgrade soils for construction of the grade beams and garage floor slab. This crushed stone pad should be a minimum of 12 inches thick. If construction traffic is placed on the crushed stone the thickness should beincreased to a minimum of 24 inches. A way to stabilize a spongy, but suitable, virgin, subgrade would be to spread a reinforcement or separation type of geo- textile (Mirafi 600X or approved equal) on the subgrade and follow with a lift of clean, granular fill or uniform crushed stone. The thickness of the controlled fill can range from 1.0 to 2.5 feet, as necessary, to achieve a working mat upon which to construct the remainder of the controlled fill or to place footings. If uniform crushed stone is used as controlled fill a layer of geotextile should be placed between the crushed stone and any sand/gravel controlled fill or virgin soil. Controlled Fill: Before any controlled fill is placed the site should be inspected to verify that the site has been prepared according to the recommendations contained in this report as required by the current NXS Building Code. Controlled fill can consist of non -organic, on -site or imported soils free of debris and expansive soil/rock and having a maximum particle size of 3 inches. A gradation and proctor should be performed on the proposed soil and submitted to me for approval. Approved, properly placed and compacted material can be used as controlled fill within the proposed building footprint. Free draining controlled fill material should be placed as recommended in this report. Approved on -site or imported soils should not be used in these locations where free draining controlled fill is recommended unless approved by me. Controlled, relatively clean, granular fill can be spread in lifts not exceeding 12 inches in loose thickness. These materials should be compacted to a minimum of 95 percent of the maximum ASTM Specification D 1557-91 density, modified proctor. On -site, silty soils, will be difficult to compact during wet weather or poor drying conditions. These soils should not be used as controlled fill. If crushed stone is used as controlled fill, it should have a layer of geotextile with a minimum tensile strength of 200 lbs should be placed between the stone and existing soils. The stone should be placed in lifts not exceeding 12 inches in thickness and should be compacted with a, minimum of 5 passes of a 8 vibratory roller rated at 5 tons or larger. Weathered shale or crushed shale should not be used as controlled fill within the proposed building area. Free Draining Controlled Fill Material: Naturally or artificially graded mixture of sand, natural or crushed stone or gravel conforming to NYS DOT 'fable 733-04A, Type 2 or 4 as follows and free of any organics, expansive material or asphalt products: U.S. Sieve No. 2 inch 1/4 inch No. 40 No. 200 Percent Passing by Weight 100 30-65 5-40 0-10 NYS DOT Table 703-4, Size 2 crushed stone, clean, durable, angular, and of uniform quality throughout and non -expansive: U.S. Sieve No. 1 '� inch 1 inch 1/2 inch Percent Passing by Weight 100 90-100 0-15 All controlled fill should be free of organic and/or frozen material. Free -draining controlled fill should have less than 10 percent fines passing the #200 sieve. I recommend performing one field density test for every 2,000 square feet of controlled fill placed, within the overlaying building footprint, but in no case fewer than three tests per lift. I recommend that for foundation wall backfill that in each compacted backfill layer have at least one field in place density test for each 50 feet or less of wall or footing length, but not fewer than two tests along a wall face be performed per lift. Walls should be backfilled uniformly on each side of the wall to prevent uneven lateral loading on the wall, unless the wall is designed as a retaining wall. 0 Proper placement and compaction of backfill along exterior portions of foundation walls should. be provided, especially in locations where there are sidewalks or building entries. Proper placement of backfill materials can reduce possible settlements and the use of properly designed backfill and drainage can reduce possible frost heave movements. Results of the field compaction test results should be sent to my office for review. Copies of the results of soil gradation tests should also be provided to me for review and approval. Building Foundations: I recommend that the proposed structure be supported by deep foundations such as mini -pile or helical piles that extend into bedrock or the dense sand and clayey silt soils below 50 feet. The. pile design should be performed by qualified others. I recommend that the owner perform a cost estimate with both options to determine which option may be the most cost effective. For the mini -pile estimate I would estimate that the piles would extend a minimum of 75 feet below the existing ground surface and then at least a 10 feet embedment in the possible bedrock. Preliminarily a rock socket :side friction of 100 psi could be used for design. Additional borings(s) would be required to more accurately determine the cost and side friction values if this option is chosen. For estimating purposes for the helical pile option. I would assume a minimum depth of 50 feet. Piles that extend deeper will have higher capacities. For the estimate, depending on the depth that helical piles are advanced into denser soils, they could achieve capacities of between 20 and 30 kips per pile. Test piles should be installed to more accurately determine the design capacity. Loads from adjacent footings, utilities or structures should be assumed to distribute based on the elastic theory. Typical Boussinesq charts can be used to approximate loads at various depths and locations due to adjacent structures. 10 Exterior grade beams in unheated areas should have a minimum of 4.0 feet of embedment for protection from frost action. All walls that retain soil on only one side should have a drain tile placed along the base of the wall. The drain tile should be a minimum of 4 inches in diameter, surrounded by a minimum of 6 inches of properly graded washed sand or crushed stone wrapped with a non -woven filter fabric with a maximum apparent opening size of 70 and a minimum trapezoid tearing strength of 100 lbs. The drain tile should drain to a stormwater sewer, daylight, or a sump equipped with a pump. The wall should then be backfilled with a controlled, well graded, free -draining granular material. The material should extend away from the wall a horizontal distance of two-thirds the height of the fill being placed. The upper 1 foot of material should be a fairly impermeable material to shed surface water and should be pitched away from the building to provide proper drainage. If these procedures are used, a static lateral soil pressure of 40 psf per foot of retained soil can be used for design of the wall. This static, active lateral soil pressure is based on a moist unit weight of 125 pcf and an angle of internal friction of 32 degrees. If the retaining wall is braced or if the deflection is limited prior to back.filling so the active soil pressure is not achieved, a static, at -rest lateral soil pressure of 63 psf per foot of retained soil can be used for design. To resist overturning and sliding a static lateral passive pressure of 250 psf per foot of embedment can be used, provided foundations are backfilled with controlled fill. This static, passive pressure resistance value has been reduced from the calculated full passive pressure because of stress/strain characteristics of the soil. To develop the full, calculated resistance a certain amount of movement or deflection in the structure is required. The amount of movement required to generate this resistance generally greater than is acceptable for structures. I therefore recommend that the full passive pressure not be used. 11 Any surcharge loading of existing adjacent building foundations or other adjacent structures/utilities should be addressed by the structural engineer using Boussines.q charts. Floor Slabs: Concrete floor slabs can be designed to rest on grade beams that in turn are supported by pile foundations. I recommend that a minimum of a 4 inch thick layer of compressible material be placed over the pipe that extends under the proposed building and the under the floor slab to allow some settlements to occur without imposing loads on the pipe. Exterior/unheated concrete/asphalt pavements will experience some frost heave movements during the winter and spring. If these movements are not acceptable then a minimum of 4.0 feet of approved subbase material and properly designed drains would be required below the concrete/asphalt pavements or sidewalks. The use of properly designed footing drains can also be used to reduce possible frost heave movements adjacent to the proposed structure. If the moisture levels of floor slab areas are critical additional drainage materials and vapor barriers will be required beneath the door slab. Also, the moisture content of the subbase soils should be carefully monitored to prevent excess water from saturating these subbase soils before the floor slab is poured. This aspect of the design should be performed by qualified others. Seismic Conditions: The potential seismic conditions at the proposed site have been investigated using the information provided in the NYS Building Code, ASCE/SEI 7-22 and the boring information obtained during my investigation and past experience with soils in the area. Based on the soil boring information and my experience it is my opinion that the Site Classification (ASCE-7 Table 20.3-I) could be assumed to be D. Using data from Reference Document ASCE/SEI 7-22, Risk Category I, I estimate that the MCE spectral acceleration (Sms) at short periods is 28.0 and the MCE spectral acceleration (Smi) at 1 s period is 12.0. 1 have included a copy 12 of the spectral accelerations .for other Hazard Levels in the appendix of this report. The probabilistic ground motion values are for rock site class B. Peak ground accelerations in the upper soil profile may vary. If specific peak ground accelerations or shear wave velocities are required for the upper soil profile additional testing would be required. If it is determined by the structural engineer that the Seismic Design Category is D, E or F additional geotechnical recommendations can be provided. The soil borings and my analysis do not indicate any significant potential seismic hazards such as liquefaction, sensitive clays, weakly cemented soil, or surface rupture. CONSTRUCTION PROCEDURES AND PROBLEMS: The NYS Building Code requires special inspections and follow up reports. These inspections should be performed to verify compliance with the recommendations contained in this report. All excavations of more than a few feet should be sheeted and braced or laid back to prevent sloughing in of the sides. Excavations should not extend below adjacent footings or structures unless properly designed sheeting and bracing or underpinning is installed. A layer of geotextile (min. tensile strength of 200 lbs) and 12 to 24 inches of crushed stone may be required in excavations to prevent disturbance of the subgrade. The stone and fabric should be placed as described in the Controlled Fill section of this report. Sump -pit and sump -pump -type dewatering may be required in excavations or low areas during wet weather or if groundwater is encountered. If large quantities of groundwater are encountered vacuum wells maybe required to stabilize the subgrade soils. All excavations should be dewatered to a minimum of 1 foot below the bottom of the excavation. All dewatering programs should be designed to prevent bottom heave. Any dewatering program should be performed with properly designed filtration protection on all pumps to prevent loss of ground. 13 As previously noted, the on -site soils contain clayey silt which will make the soils sensitive to moisture content. If the material becomes wet or saturated, it will become spongy and easily disturbe.d.. It will also be difficult to place as controlled fill if it becomes too wet. Imported well draining sand and gravel or possibly crushed stone may be required to prevent disturbance of the subgrade soils during construction and in roadway areas. Additional subbase, up to 24 inches of total thickness, may be required to support traffic loadings. Any areas of the pavement subgrades that become disturbed during construction should be removed and replaced with subbase materials. Subgrades should be kept from freezing during construction. Water, snow, and ice should not be allowed to collect and stand in excavations or low areas of the subgrade. Some obstacles, including foundations and utilities and cobbles/boulders and possibly bedrock, will be encountered while installing piles. Design and construction limit the potential for shrinkage properties of the curing of the concri between the top and boti in curling of the slak through the slab should be only indirectly rela structural engineer shoe procedures should include measures to slab curl and vapor transmission. The the concrete. should be controlled and to controlled. Differential shrinkage am of the slabs could otherwise result s. The control of vapor transmission also be addressed. These phenomena may :ed to soil conditions. The architect/ ld address this aspect of the design. Current American Concrete Institute recommendations for the design and construction of floor slabs and the control of shrinkage, slab curl and vapor transmission can be referred to. Final Geotechnical Recommendations: As noted, the estimated preliminary design values provided in this report are for cost estimating purposes, NOT for final design. After the cost estimating has been completed additional testing including soil boring(s) and test pile installation and testing will be required to provide final design recommendations. The design of all pile foundations should be performed by a qualified design build contractor/engineer.

The scope of the project and` Iocation described herein, and my description of the project represents my understanding of the significant aspects relevant to soil and foundation characteristics. In the event that any changes in the design or location of the proposed facilities, as outlined in this report, are planned, I should be informed so the changes can be reviewed and the conclusions of this report modified or approved in writing by myself. It is recommended that all construction operations dealing with earthwork and foundations be inspected by an experienced soil engineer to assure that the design requirements are fulfilled in the actual construction. If you wish, I would welcome the opportunity to review the plans and specifications when they have been prepared so that I may have the opportunity of commenting on the effect of soil conditions on the design and specifications. The analysis and recommendations submitted in this report are based upon the data obtained from the soil borings and/or test pits performed at the locations indicated on the location diagram and from any other information discussed in the report. This report does not reflect any variations which may occur between these boring and/or test pits. In the performance of subsurface investigations, specific informatioon is obtained at specific locations at specific times. However, it is a well-known fact that variations in soil and rock conditions exist on most sites between boring locations and also such situations as groundwater conditions vary from time to time. The nature and extent of variations may may not become evident until the course of construction. If variations then appear evident, it will be necessary for a reevalua- tion of the recommendations of this report after performing on -site observations during the construction period and noting the characteristics of any variations.
