101 1 INTRODUCTION As requested, LVM MERLEX has carried out the geotechnical investigation for the proposed addition to the Temiskaming Veterinary Services building located at 191 Drive-In Theater Road in (see Key Plan, Drawing Nos. 1a and 1b, Appendix 1). For the purposes of this report, Drive-In Theater Road is considered to be oriented in an east-west direction. We have completed the field and laboratory testing programs and submit the factual results in this report along with our comments and recommendations. It is understood that it is proposed to construct a new one storey addition along the west site of the existing structure (see Drawing No. 2, Appendix 1). The building is proposed to have a slab on grade. The purpose of this geotechnical investigation was to assess the subsurface soil and groundwater conditions in the area of the proposed building and surrounding property to address the following items: Subsurface Information (i.e. soil classification, elevation of the water table at the time of investigation, refusal depths, etc.); Geotechnical Recommendations pertaining to this project/site (i.e. foundation type, bearing capacity, foundation depth, frost protection, drainage requirements, site classification for seismic site response, slab on grade construction, possible reuse of site excavated soil, imported fill, and/or excavations and backfilling). 2 FIELDWORK The fieldwork for this geotechnical investigation was carried out on January 8 th, The fieldwork consisted of two (2) sampled boreholes (Boreholes (BH) Nos. 1 and 2). The locations of the boreholes are shown on the Borehole Location Plan, Drawing No. 2 in Appendix 1. The boreholes and auger probes were advanced with a bombardier mounted CME-45B drill rig equipped with continuous flight hollow stem augers. The field work was under the full time direction of an experienced member of our engineering field staff who was responsible for underground service locates, logging individual borings, retrieving samples, field sample classification, plus overall field/drill supervision. At select boreholes, samples were obtained at frequent intervals of depth by using the Standard Penetration Test (SPT) method. The SPT method of sampling involves advancing a 50 mm outside diameter split spoon sampler with the force of a 63.5 kg hammer, freely dropping 760 mm, mounted in a trip (automatic) hammer. The number of blows per 300 mm penetration is recorded as the N value. All samples taken during this investigation were stored in labeled airtight containers for transport to our North Bay laboratory for visual examination and select laboratory testing. When cohesive deposits were encountered, the in-situ strength was measured using an N size field vane, vane collar, and calibrated torque meter. The routine laboratory testing consisted of natural moisture content determination and Atterberg Limits testing on select samples. Advanced laboratory testing 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 1

102 involved one-dimensional consolidation testing. Samples remaining following testing will be stored for a period of three months following the date of this report and then discarded unless otherwise instructed. In order to comply with the intent of Ontario Water Resources Act Regulation 903 amended to O. Reg. 128/03, the boreholes were sealed with reverse augering techniques for the full depth and, where appropriate, the surface was sealed with a bentonite plug. The ground surface elevations at the borehole locations were measured based on a temporary benchmark described as the top of the floor slab of the existing building. This temporary benchmark was reported by others to have an elevation of m. All measurements in this report are in Metric units (unless otherwise noted). 3 SUBSURFACE CONDITIONS Soil conditions are confirmed at the boring locations only and may vary between borings. The boundaries between stratums indicated on the borehole logs are inferred from non-continuous sampling, results of in-situ tests (i.e. SPT, etc.), observations during the drilling operations, and/or the response of the drilling equipment. These boundaries are approximations only and should not be regarded as exact planes of geological change as the actual transition may be gradual from one soil type to another. The description of compactness of the granular subsoils, in part, was based on the results of the SPT, DCPT and/or the response of the drilling equipment. The consistency of very fine cohesive subsoils, if encountered, was based on in-situ vane tests. Refusal is defined as the point at which the augers can no longer be practically advanced with the equipment used in this investigation. Refusal to further advance of the augers, DCPT and/or SPT may have been due to fill, the presence of very dense soils, cobbles/boulders in the underlying soils, or possibly bedrock. Defining the nature of auger refusal with diamond drilling operations was beyond the terms of reference for this project. Detailed descriptions of the subsurface conditions revealed at the boreholes are shown on the enclosed Record of Borehole Logs in Appendix 2. The following is a brief description of revealed subsurface conditions at this site. 3.1 SUBSURFACE SUMMARY DESCRIPTION The ground surface elevations at the borehole locations ranged from to m. At surface at BH Nos. 1 and 2, a layer of surficial organic soil some ±50 mm thick was penetrated. Underlying the surficial organic soil at BH Nos. 1 and 2, a deposit of brown silty clay was penetrated. A transition from brown to grey was observed at depths of 3.6 and 3.8 m at BH Nos. 1 and 2, respectively (elevation and m, respectively). The natural moisture content measured on samples of this deposit was in the order of 23 to 71%. Atterberg Limits testing was carried out on five (5) samples of this deposit, the results of which indicated a Liquid 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 2

103 Limit in the order of 64 to 88% and a Plastic Limit in the order of 23 to 27% (see Figure No. L-1, Appendix 3). One-dimensional odometer (consolidation) testing was carried out on one sample of the grey silty clay deposit. Results of the consolidation testing indicated a preconsolidation pressure in the order of 160 kpa. The over-consolidation ratio (ratio of preconsolidation pressure to overburden pressure) is in the order of 2.4. Based on this relationship, this clay is described as over-consolidated. Based on in-situ shear strengths of 34 to greater than 100 kpa, the consistency of this deposit was described as firm to very stiff. In general, the greater shear strengths were encountered within the upper 3 to 4 m thickness of the deposit. The sampling was terminated in this deposit at a depth of 6.9 m below existing grade at BH Nos. 1 and 2 (i.e. elevations ±204.2 and m, respectively). 3.2 GROUNDWATER DATA Groundwater and cave-in levels in the open boreholes were measured, where possible, during the advance of the individual borings and upon completion. At the time of the completion, the boreholes were dry. It is noted that there may have been insufficient time for the groundwater levels to stabilize in the boreholes prior to measurement. The brown to grey interface is generally a good indication of the permanent groundwater level. Based on the brown-grey interface, the groundwater level is estimated at elevations ±207.0 to m. Groundwater levels will fluctuate seasonally/yearly. 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 3

104 4 DISCUSSION AND RECOMMENDATIONS The existing Temiskaming Veterinary Services building is located at 191 Drive-In Theater Road in. It is understood that it is proposed to construct a new one storey addition along the west site of the existing structure (see Drawing No. 2, Appendix 1). The addition will be some 287 m 2. The building is proposed to have a slab on grade. It is understood that the area between the addition and west property line will be used for an access lane for deliveries. It is understood that the existing grade in the area of the proposed addition varies by up to 1.1 m. As such, consideration has been given to raising the grade around the proposed addition. 4.1 OVERBURDEN DISCUSSION The ground surface elevations at the borehole locations ranged from to m. In general, the overburden consists of firm to very stiff silty clay. The upper 3 to 4 m of the deposit was brown in colour indicating desiccation and the strength of the clay in this upper layer was described as very stiff. The depth to the groundwater table was estimated at between elevations ±207.0 to m. Groundwater levels will fluctuate seasonally/yearly. Based upon the geotechnical data, the existing native soils in their undisturbed state or with improvement where required, will support the proposed structure on conventional footings (i.e. reinforced concrete strip and spread footings). The placement of fill to raise the grade over a large area however, will be the constraining factor for development of this site. 4.2 FROST PROTECTION The estimated frost depth penetration for the area of the subject site is: ±2.2 m below exposed asphalt surfaces or for isolated, unheated foundations ±2.0 m for exterior footings in a heated structure below exposed surface (i.e. adjacent sidewalks, etc.); ±1.8 m for naturally insulated (i.e. snow cover) exterior footings for a heated structure. All exterior footings and isolated footings subject to frost penetration and stripped of the natural insulative value of snow cover must have frost protection (permanent and during construction) to the depths noted above. If a sufficient depth of earth cover cannot be provided for frost protection, equivalent expanded extruded polystyrene (EEP) insulation may be used in conjunction with available soils cover to provide frost protection. If EEP is used for frost protection, precautions must be taken to protect the insulation from accidental spillage of hydrocarbons, solvents or other destructive products. Foundations can be founded at a higher elevation (i.e. 600 to 900 mm below finished grade) provided they are supported on approved subgrades and insulated. The following insulation design can be used. The following insulation design was based on the generalized design 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 4

105 curves (Robinsky and Bespflug, 1973) for minimum insulation requirements for heated structures founded on silty or clayey soil. Synthetic insulation (i.e. Styrofoam HI-40 or equivalent), minimum 50 mm thick, should be placed down the face of the foundation wall to the top of the footing and then extend horizontally outwards beyond the foundation edges a minimum of 1.2 m. The horizontal insulation should be sloped downwards slightly (i.e. 2 to 3%) to promote drainage away from the structure. The insulation should be overlapped (or step jointed) and pegged or spot glued together. The insulation must be unbroken and any damaged pieces must be replaced. To reduce the risk of damage to the polystyrene insulation from an accidental hydrocarbon spill, it is recommended that the insulation be covered, where appropriate, with a layer of 6 mil polyethylene (i.e. maintenance areas, garage entrances, below parking lots, etc.). The founding subgrade must be protected from frost at all times during foundation excavation and construction operations. Concrete cannot be placed against materials with subzero temperatures (i.e. subgrade, rebar, formwork, etc.). Should freezing temperatures occur during construction, the founding subgrade must be insulated (straw, insulated traps, etc.) against frost until such a time that footings are adequately protected (soil cover, insulation etc.) and, if required based on footing depth, heat is supplied to the building. 4.3 SITE DEVELOPMENT The finished floor of the existing building is at The existing building has a basement with floor elevation at m. Grade elevation along the west side of the building is at ±211 m. As previously noted, the grade slopes down towards the west in the area of the proposed addition, ranging from elevation m to m at the western site boundary. Based upon the spot elevations provided on the survey drawing, it appears that the material removed for the basement was placed around the existing structure and tapered out. If the existing floor slab elevation is matched, this will require the grade to be raised by 0.8 m in the eastern area of the addition and by some ±1.5 m in the western area Settlement Based on the consolidation testing carried out at this location, a series of settlement estimates were carried out for various heights of fill used to raise the grade. It should be noted the settlement at this site will be differential, since the depth of fill, and thereby the load, will be differential. The estimates are tabulated below. GRADE RAISE (m) ESTIMATED RESULTING LOAD (kpa) ESTIMATED MAGNITUDE OF SETTLEMENT (mm) ± ± ± ± ±5 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 5

106 As noted, if the finished floor of the proposed addition is established at m, select areas of the site will require from 0.6 to 1.5 m of fill. Total settlements could therefore range from ±20 mm to 40 mm, and differential settlement would be excessive. As can be seen from these estimates, the placement of area loads could result in settlements outside of tolerable limits for this building addition. If fill placement is limited to small, isolated areas, the estimated settlements will be smaller in magnitude Options to Minimize Settlement In order to minimize total and differential settlement, the new loads placed on the site must be limited or settlement induced prior to construction. Firstly, the site could be preloaded to induce settlement to occur prior to construction; however, settlement will take several years to be substantially complete. This process could be quickened through the installation of wick drains and/or increasing the magnitude of the preload. Alternatively, the building finished floor could be lowered to minimize the need to raise the grade. Based on the settlement estimates, it is recommended that grade raise (both to the interior and exterior), be limited to a maximum of 600 mm or less above existing grades. If the finished floor of m must be maintained, consideration could be given to installing a basement or crawl space into the design. Alternatively, the use of lightweight fill, such as cellular concrete, or block insulation could be used to raise the grade. 4.4 FOUNDATION RECOMMENDATIONS Provided the site and subgrade is properly prepared as discussed herein, the proposed structure may be founded on conventional concrete strip and/or spread footings at the depth required for frost protection or higher, if insulated. However, it is again emphasized that the nature of the native silty clay at this site can result in excessive differential settlements of the site if the grade is raised, which can also influence the footings (see Section 4.3.1). To minimize differential movement, we recommend that the footings for the proposed structure be constructed of reinforced concrete and that the foundation walls be constructed of reinforced concrete dowelled into the footings, or masonry block, grouted and doweled into the footings. A control joint should be installed between the new addition and the existing building. The footings for the new addition should be established at the same elevation as the existing footings. At no time during the new construction shall the existing foundations be undermined without proper bracing/shoring. At 2 m perpendicular to the existing building the footings can then be stepped up or down to the founding elevation at the depth required for frost protection. The ground surface elevations at the borehole locations ranged from ±210.5 to m. The finished floor elevation has not been established, due to site constraints as noted above, however, the will be founded in the very stiff native silty clay. 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 6

107 Interior footings not subject to frost penetration and outside the area of influence of the exterior footings may be founded at a higher elevation provided they are a minimum of 600 mm below the underside of the slab on grade and founded on approved engineered fill supported on the approved native soils. If necessary, engineered fill below the footings should consist of an imported material meeting OPSS for Granular A or Granular B Type II (50 mm minus), compacted to 100% SPDD. It should be noted that Granular B Type II is a manufactured material consisting of 100% crushed quarry stone. Any granular material to be used as engineered fill on this site must be tested and approved by this office prior to delivery to the site. The area of influence below the foundation, in cross section, is described as a trapezoid that extends outwards, horizontally from the edges of the foundation, a minimum of 300 mm and then downwards on a 45 outward angle to undisturbed native competent soil. 4.5 BEARING CAPACITY All fill, organics, and other deleterious materials must be removed from the area of influence of the foundations down to native subgrade. The natural silty soils at this site are highly susceptible to disturbance when wet. Groundwater is not anticipated however, if encountered it must be properly controlled during the full period of foundation excavation and construction, to minimize the potential for subgrade disturbance. All founding subgrades must be inspected and approved by a qualified member of this firm prior to forming footings or placing engineered fill. The contractor should minimize worker traffic within the foundation formwork and the excavation must be maintained in an unwatered condition during foundation construction. If the founding subgrade is excessively disturbed during excavation and foundation construction operations, it may have to be subexcavated and replaced with engineered fill or non-shrink fill. Footings should be a minimum of 450 mm wide. The design is based upon the assumption that the footings will be properly formed and any required rebar is placed in accordance with RISI practices. Backfill around the foundations should consist of a well graded free draining Granular B Type III (see below). For footings established at the depth below finished grade required for frost protection (i.e. 2.0 m), and supported on approved native undisturbed soils or on properly constructed engineered fill (i.e. 100% SPDD) supported on undisturbed natural soils: Factored Geotechnical Resistance at ULS: 100 kpa Geotechnical Reaction at SLS of 25 mm total settlement: 78 kpa net bearing pressure increase For footings established at a shallow depth (i.e. 0.6 m) and insulated, and supported on approved native undisturbed soils or on properly constructed engineered fill (i.e. 100% SPDD) supported on undisturbed natural soils: Factored Geotechnical Resistance at ULS: 200 kpa 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 7

108 Geotechnical Reaction at SLS of 25 mm total settlement: 78 kpa net bearing pressure increase Based on this design bearing pressure, and assuming proper subgrade preparation, settlements of the foundation units on soil for the structure will be well within the generally accepted tolerance range for this type of structure (i.e. 25 mm total and 19 mm differential) Lateral Earth Pressure The foundation may be designed as retaining walls. Backfill behind retaining walls should be an imported well-graded free draining material (i.e. Granular B Type III) and be compacted to a minimum of 98% SPDD below settlement sensitive areas. Compaction efforts within 1.8 m of the retaining wall should be carried out with small hand operated compaction equipment and should not commence until the wall is properly supported with floor joist or braced. Drainage must be supplied behind the retaining wall to negate the risk of hydrostatic pressure buildup. The following parameters may be used for calculating lateral earth pressures. PARAMETER GRANULAR A GRANULAR B TYPE NATIVE SILTY CLAY III Unit Weight, γ (kn/m 3 ) Shear Strength (kpa) Angle of Internal Friction ( ) Coefficient of Active Earth Pressure (Ka) Coefficient of Passive Earth Pressure (Kp) Coefficient of Earth Pressure at Rest (Ko) Since the below grade reinforced foundation walls for a building are essentially rigid, the at rest (Ko) coefficient of earth pressure should be used in the design. 4.6 SITE FINISHES AND OTHER CONSIDERATIONS Connections to the building and/or running below the main floor (sewer or water lines, underground cables, etc.) should be flexible in nature and/or securely fastened to the rigid structure. Site finishes should be designed to allow future adjustment to accommodate future settlements. 4.7 SLAB ON GRADE Slab on grade construction may be used at the subject site. However, it should be noted that if the grade is raised to allow for slab on grade construction, differential settlement due to the increase load may occur as previously discussed. All deleterious materials (i.e. fill, organics, etc.) must be removed from below the slab on grade down to the natural subgrade and the resulting surface inspected and approved. The contractor should be prepared to locally excavate deeper to remove unacceptable areas that may become apparent during construction operations. The approved subgrade can then brought up to the underside of the vapour retarder 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 8

109 with engineered fill consisting of an imported granular material meeting OPSS SP110F13 for Granular B Type III compacted to a minimum 98% SPDD or better. A well-graded coarse grained soil is described as having no excess particles in any size range with no intermediate sizes lacking (i.e. smooth, concave distribution curve). Generally, the distribution curve for this backfill should fall in the middle of the specification and be limited to maximum sized particles of 75 mm or less (to prevent damage when backfilling against underground structures) and should contain at a minimum 2% fines to facilitate compaction efforts. The use of a well-graded material will facilitate compaction operations. The use of a vapour retarder will be dependent upon the floor coverings to be used and the floor covering manufacturers recommendations should be followed. For preliminary design, a manufactured vapour retarder system (i.e. min 6 mil polyethylene, etc.) over top of the engineered fill may be used. The vapour retarder manufacturer s specifications must be adhered to (minimum overlaps, taping/sealing at openings, sealed around utility and foundation or column perforations, etc.) and the integrity of the system must be maintained (i.e. no holes, tears, or other perforations). The concrete supplier and finisher should undertake to use a mix and placement methodology that will minimize the potential for slab curling. 4.8 EARTHQUAKE PARAMETERS Considering the variable overburden conditions and the known geotechnical values, soil liquefaction is not considered an issue, and based on NBCC 2005, Table A, Site Classification for Seismic Site Response, the subject site would have Site Class E. 4.9 DRAINAGE It is understood that the building will not have a below grade structure (i.e. basement) and, as such, full perimeter footing drains and underslab drainage should not be necessary provided the floor slabs are a minimum of 150 mm above exterior grade. The surface of the finished grade around the exterior of the building should be relatively impermeable and contouring of the perimeter exterior grade surface must direct all surface waters away from the structure. However, the permeable backfill around the foundations will collect water due to the relatively impermeable native soils. The water will drain towards the weeping tile around the existing building. Installing weeping tile around the addition will provide quicker drainage. As the existing building has a weeping tile with positive outlet, and in consideration of the economics of installing weeping tile for the addition, it is recommended that the addition include a perimeter weeping tile at the foundation level. If a crawl space or basement is used, the building must be provided with drainage. Properly installed continuous drainage will prevent groundwater from entering the lower levels of the structure and also reduce the risk of hydrostatic pressure buildup (see Figure A, Appendix 4). Drainage should consist of a minimum 100 mm diameter weeping tile or equivalent perforated pipe leading to a sump or other positive outlet. The weeping tile should be surrounded by an approved porous geotextile membrane to prevent the entry of fines into the system.

110 perimeter drainage, the invert of the pipe should be established a minimum of 300 mm below the interior grade. On the interior, the obvert of the drains should be a minimum of 100 mm below the bottom of the crawl space grade. The pipes should be placed on a 100 mm thick bed of 19 mm clear stone and should also be surrounded on the sides and top with at least 100 to 150 mm of 19 mm clear stone or concrete sand. Perimeter drainage should be independent of interior drainage. Walls below exterior grade must, at a minimum, be damp proofed. Contouring of the perimeter exterior grade surface must direct all surface waters away from the structure and discharges from rainwater leaders must be adequately controlled. Backfill around the foundations and foundation walls should consist of a well-graded free draining granular material EXCAVATION, BACKFILL, AND DEWATERING Based on the Occupational Health and Safety Act Regulations for Construction Projects, the soil at this site is classified as Type 3. All excavations greater than 1.2 m in depth must be sloped or shored in accordance with the Occupational Health and Safety Act Regulations for Construction Projects. Short-term (i.e. day) open excavations will be stable above the groundwater table at a temporary angle of 1H:1V, however excavations established at this slope must not be left unattended at any time. Below the prevailing groundwater table, the slopes of open excavations will have to be flattened to 2H:1V or possibly shallower depending upon the method of dewatering employed. A dry subgrade condition must be maintained at all times during foundation construction until both footing and foundation wall construction, and backfilling, are a sufficient height above the prevailing water table (i.e. at a minimum 1 m). During these investigations, the groundwater table was estimated at elevations of ±207.0 to m. Temporary construction groundwater control can generally be carried out to a depth of approximately 750 mm to 1.0 m below the prevailing groundwater table using the conventional construction dewatering methods of using oversized excavations and installing perimeter drains/ditches leading to a sufficient number of strategically placed filtered sump holes located in the base of the excavation outside the area of influence of engineered fill and/or foundations. It is noted that the efficiency of conventional sump holes to control the groundwater depends highly upon the number of sumps, the depth of their base below the ultimate subgrade level, method of construction (i.e. cased and filtered sump hole versus a pump at the base of the excavation), and their spacing. In our experience, to be efficient at groundwater control, conventional sump holes should not be placed more than 10 m apart, preferably less, although placement is highly dependent upon soil types (permeability, etc.) and conditions, depth of sump holes, as well as the intent of the project. Where greater draw down is required, a more sophisticated dewatering system, such as vacuum well points, will have to be used to maintain an unwatered, stable subgrade. It is suggested that any dewatering system be installed and operated by a qualified dewatering subcontractor. In order to be effective any dewatering 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 10

111 operation must be started well in advance of the excavating operations and be run continuously throughout the subsurface construction operations. A permit to take water is required by the MOE when more than 50,000 litres/per will be removed. It must be emphasized that, when wet, silty soils (such as encountered at this site) can be easily disturbed through excavation operations, foot traffic, etc. and such disturbed soils can lose a significant amount of the native bearing. To minimize the potential for disturbance, the groundwater must be drawn down a sufficient depth below the base of the excavation (i.e. 500 mm to 1 m). Ultimately, the method of dewatering will be the choice of the contractor. The importance and benefits of maintaining a dry stable subgrade during excavation and foundation construction cannot be stressed enough. Failure by the contractor to adequately control the groundwater, and/or rainwater, surficial runoff, etc., can result in disturbance to the founding subgrades, which can result in having to carry out corrective measures (i.e. additional excavation, time delays, etc.) to improve the subgrade. Corrective measures required to improve subgrades where groundwater is not adequately controlled will be at the Contractors cost. As part of the Contractors proposed methodology of construction, the Contractor should be requested to submit a dewatering plan prior to commencement of the project that details how they will control groundwater. The plan should include all aspects from methodology (i.e. sump holes and pumps, drainage ditches, vacuum well points), to construction of system (sump hole details, placement, etc.), to operation of system, etc. Backfill around the foundations should consist of a well graded free draining Granular B Type III. The fill on site was not found to consistently meet OPSS for Granular B Type III. Native excavated soils can only be reused on site for landscaping purposes, or in areas where the future settlement of the ground surface is of negligible concern. The removal of any soil from the site must comply with Ontario Regulations. Any granular material to be used as engineered fill on this site must be tested and approved by this office prior to delivery to the site. It should be noted that engineered fill(s) should be placed in lifts of thickness less than the effective compaction depth of the equipment used to carry out the compaction operations (i.e. if using a heavy diesel Wacker lifts should be a maximum of 300 mm thick, etc.) FLEXIBLE PAVEMENT DESIGN The production of a long-lasting, quality pavement structure is highly dependent upon several factors. The pavement structure that supports and distributes the traffic load consists of three separate layers: the subbase, base, and wearing surface. This, in turn, is supported by the subgrade. The long term performance of the pavement structure is highly dependent upon the uniformity of these layers. A uniform subgrade cross-section must be maintained below the 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 11

112 entire pavement structure, free of depressions, and properly sloped towards adequate drainage facilities. Generally, the overburden at this site consists of native silty clay. Based on tactile review, the native sands generally have a low to medium susceptibility to frost heaving. The subgrade below the pavement structure must have a uniform (i.e. consistent subgrade type, moisture and density conditions, etc.) cross section within the depth of frost penetration to reduce differential heaving. Proper subgrade tapers must be provided between areas where the native subgrade is encountered at different depths below existing grade, where different types of subgrade are encountered, or where service trenches are installed below the pavement structure, to provide a uniform subgrade transition to minimize the risk of differential heaving. Proper frost tapers impart a gradual heave and as such are less noticeable. Standard frost tapers for highway construction are established at a minimum of 10H:1V slope for centerline culverts etc. Considering the low anticipated speeds in the parking lot these tapers may be reduced to 5H:1V, however, it must be noted that differential heaving will be more noticeable where the steeper taper is used. If service trenches are installed outside of the asphalt area, frost tapers will not be required. Every effort must be made to prevent disturbing the founding subgrade during excavating and construction operations. All deleterious surficial materials (i.e. fill, organic soil, topsoil, disturbed soil, etc.) should be stripped from below the area of influence of the pavement structure. Some isolated areas may require deeper excavations if areas of weak/poor subgrade become evident during construction. Once stripped, the subgrade must be approved by a qualified member of this firm. The surface of the subgrade underlying the subbase course must be crowned at a minimum of 3% cross fall gradient towards a positive drainage system (i.e. subdrains, ditch, etc.). Once the site is stripped of deleterious materials down to approved uniform subgrade, engineered fill may be required to raise the site from approved native subgrade to underside of the pavement structure. If backfill is required to raise the site from approved subgrade to underside of the pavement structure (subbase), it is recommended that, at a minimum, a material meeting OPSS for a well-graded Select Subgrade Material (SSM) is used. It is understood that a Superpave asphalt will be used for this project. As such, provided the subgrade is properly prepared and is uniform, we recommend the following pavement structure. PAVEMENT STRUCTURE HEAVY DUTY - MAIN ROADS, BUS ROUTES, ASSESS ROADS, ETC. LIGHT DUTY (I.E. CARS ETC.), PARKING LOTS HL3 or HL4 Surface Course 50 mm 50 mm HL4 Lower Binder 40 mm Base (OPSS Form 1010 Granular A) 150 mm 150 mm Subbase (OPSS Form 1010 Granular B Type I) 300 mm 300 mm 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 12

113 The binder course has been specified to be thinner than the surface course to allow the surface course to be of uniform thickness when paving beyond those areas requiring a binder course. If heavy duty design is used throughout the parking lot and access routes, the thickness of the binder course and surface course noted in the table should be reversed. As noted previously, the pavement structure cross-section and subgrade type must be uniform to reduce the impact of potential differential frost heaving. The surface of the pavement must be crowned at a crossfall of 2% towards ditches or other drainage facilities. The importance of draining the pavement structure (granulars) below the roadway areas cannot be stressed enough. Ditches or other drainage facilities should be provided to the paved areas. To provide positive drainage of the granular base and subbase material below the paved areas, the invert of the ditches should be placed at a minimum of 0.5 m below the underside of the subbase (i.e. Granular B Type I) level. Ditches require regular maintenance and cleaning to ensure positive drainage. If perforated drainage pipe is used for subsurface drainage, the invert of the drainage pipe should be located at the underside of the subbase layer. Based on the variable fines content in the subgrade material encountered in the borings, the perforated drainage pipe should be surrounded by an approved porous geotextile membrane or equivalent granular filter. The ditches and/or perforated drainage pipe must have a positive gradient towards an outlet or catch basin that will provide continuous drainage. Backfill around drains in trenches must be a free draining granular material Compaction All Granular A (base course) and Granular B Type I (subbase) material should be compacted to a minimum of 100% Standard Proctor Dry Density (SPDD). Imported fill (SSM) should be compacted to a similar density where possible above the prevailing ground water table Service Life A functional design life of 10 to 12 years has been used to establish the pavement recommendations. This represents the number of years to the first rehabilitation, assuming regular maintenance (i.e. route and seal, ditch cleaning, etc.) is carried out. The long-term performance of the pavement structure is highly dependent upon the subgrade support conditions. Stringent construction control procedures should be maintained to ensure that uniform subgrade moisture and density conditions are achieved. In addition, the need for adequate drainage cannot be overemphasized. The finished pavement surface and underlying subgrade should be free of depressions and should be sloped to provide effective drainage. Surface water should not be allowed to pond adjacent to the outside edges of pavement areas. 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 13

114 5 STATEMENT OF LIMITATIONS The design recommendations given in this geotechnical report are applicable only to the project described in the text and only if constructed substantially in accordance with details of alignment and elevations stated in the report. Since all details of the design may not be known, in our analysis certain assumptions had to be made. The actual conditions may however, vary from those assumed, in which case changes and modifications may be required to our geotechnical recommendations. We recommend, therefore, that we be retained and provided the opportunity during the design stage to review the design drawings, site survey information, proposed elevations, etc. to verify that they are consistent with our recommendations or the assumptions made in our analysis. It is further recommended that we be retained to review the final design drawings and specifications relative to the geotechnical recommendations. If, during construction, conditions in the field vary from those assumed at the design stage, an engineer from this office must be notified immediately. Proper subgrade preparation, groundwater control, compaction, etc. are all critical aspects of the bearing capacity of native soils. It must be noted that different aspects of the geotechnical design are based on the assumption that LVM MERLEX will be retained during site preparation and construction of the proposed works to ensure that both the geotechnical site characteristics and the construction operations/techniques are consistent with our recommendations. Should LVM MERLEX not be involved during the full construction phase, our liability is strictly limited to the factual information contained herein only. The comments in this report are intended solely for the guidance of the design engineer and address the geotechnical conditions only. The number of boreholes required to determine the localized conditions between boreholes directly affecting construction costs, equipment, scheduling, etc. would in fact be greater than what has been carried out for design purposes. Therefore, contractors bidding on this project or undertaking this work should make their own interpretations of the factual borehole results and carry out further work as they deem necessary to assess the scope of the project. Section 4 of this reported is intended for the use of the client and the design team only and is not intended to be included in the tender documents. Inclusion of the factual information (Sections 1 to 3 inclusive) in the tender documents is furnished merely for the general information of bidders and is not in any way warranted or guaranteed by or on behalf of the owner or the owner's consultants and its subconsultants or the consultants' or subconsultants' employees, and neither the owner nor its consultants or its employees shall be liable for any representations negligent or otherwise contained in the documents. 12/12/12248 G EOTEC H N IC AL IN VESTI G ATIO N PR O POS ED AD D ITIO N TO TE M IS KAM IN G VET SER V IC ES 14
