Re: Geotechnical Assessment Report Proposed Lytton Water Supply Improvements, Lytton, BC Dear Sir: 1.0 INTRODUCTION As requested, exp Services Inc. (exp) has completed a geotechnical assessment for the proposed Water Supply Improvements in Lytton, BC. The purpose of the assessment was to evaluate the subsoil and groundwater conditions underlying the site, and to provide geotechnical recommendations for the design and construction for the proposed water supply improvement project. Exp’s services have been performed in general accordance with Exhibit B of the Opus International Consultants (Canada) Ltd. (Opus) Sub-consultant agreement dated March 28, 2017. No sampling or testing of soils retrieved as part of the current exploration program was carried out with respect to environmental issues or soil corrosion. 2.0 SITE CONDITIONS AND PROJECT DESCRIPTION It is understood that the project involves the construction of a 1.4km watermain starting from the center of the Village of Lytton, crossing the CP Rail Line and Highway 1, and ending at the existing reservoirs southeast of the village. It was understood that the watermain would typically be constructed to provide 1.8m cover over the pipe. The project would also include the construction of a small UV chlorine facility at south end of the watermain and a small groundwater well building, understood to be on the school property in the village center at the north end of the watermain. The proposed alignment is reasonably flat to the west of the CP Rail Line, and slopes upwards to the east as the proposed route approaches the base of Mt. Lytton. It crosses the mouth of two ravines east of the village, and runs up along the face of another ravine. 3.0 KEY GEOTECHNICAL DESIGN ISSUES Key geotechnical evaluation and design issues for the project are:

Assess the subsurface soil and groundwater conditions;

Provide recommendations on excavation, dewatering and backfilling;

Comment on pipe crossings of the CP Rail Line and Highway 1;

Provide foundation recommendations for proposed UV chlorine facility and groundwater well building.

4.0 SUBSURFACE CONDITIONS 4.1 Surficial Geology Based on Young, G, et. al. (1992) and The Department of Mines and Technical Surveys (1958), the area is typically underlain by medium-to-coarse to coarse fluvioglacial deposits overlying medium to coarse morainal deposits. These deposits are typically described as “exceedingly stoney”, and can be expected to consist of a poorly sorted mix of boulders, cobbles, gravel, sand and silt. The topography is generally described as terraced, dissected, and hilly. The erosion of streams which created the ravines dissecting the hillside can be expected to have caused colluvium to form in the ravines. This colluvium would be derived from the fluvioglacial and morainal deposits. 4.2 Geotechnical Drilling and Subsurface Exploration Exp’s fieldwork was carried out on May 2 and 3, 2017 and included the following:

As part of due diligence, a BC One Call was made, and prior to the commencement of the drilling work, an electro-magnetic survey of the site was completed to locate buried utility lines. This survey was carried out by sub-contractor Western Locate Services Ltd. of Coquitlam, BC.

Eight test pits (designated as TP17-01 through TP17-08) were excavated to depths of about 2.1m to 3.0m, using a rubber-tire backhoe supplied by the Village of Lytton.

All field work was carried out under the full-time supervision of a member of the exp geotechnical staff, who located the test pits in the field, examined and logged the subsurface condition encountered, and collected representative soil samples for visual examination and testing in our laboratory. Following completion, the test pits were backfilled in lifts and nominally compacted by tamping with the bucket of the backhoe. Moisture content determinations were performed on select soil samples obtained from the exploration to assist in identification of soil types and to correlate with engineering design parameters. The tests were done in general accordance with the test procedures in ASTM D-2216. Results of the tests are shown on the test pit logs, provided in Appendix A. The locations of the test pits are shown on the attached Figure 1 Testhole Location Plan, and the test pit logs are presented in Appendix A. 4.3 Subsoil Conditions As described above, geological mapping of the site suggested the site to be underlain by fluvioglacial, morainal, or colluvium deposits, consisting of a poorly sorted mix of boulders, cobbles, gravel, sand and silt. The subsurface conditions encountered in the test pits were found to be generally consistent with the geological mapping. The predominant soil types encountered at the test pits were various mixtures of sand, gravel, cobbles and boulders with trace to some silt, with less frequently occurring layers of silty sand to

sandy silt also containing varying amounts of gravel, cobbles and boulders. A layer of silt to sandy silt was encountered at or near the surface and extending up to about 1.2m deep at several locations. These upper silty soils were generally characterized as firm or firm to stiff. The coarser predominantly granular soils were generally characterized as compact, with the exception of the northernmost test pit (TP17-08) where upper portion of the granular soil was primary loose to compact sand, and then became cobbly/bouldery below about 2.7m. Boulders observed in the test pits ranged up to about 1m in diameter. TP17-01 at the location of 7 Street found a pavement structure consisting of 50mm thick asphalt pavement, overlying 550mm thick well-graded, rounded, compact gravelly sand with some cobbles and trace silt. Test pit TP17-08 was added for the purposes of a potential future groundwater well building to be constructed near an existing water well at that location. This location was underlain by silt and sand fill followed by sandy silt with trace gravel and some organics to about 1.2m, underlain by loose to compact sand with some silt which became cobbly/boulder below about 2.7m depth. The proposed UV chlorine facility would be constructed near TP17-02. This location was underlain by gravelly sand with frequent cobbles and boulders at shallow depth. A Piteau Associates study for a previously proposed water treatment plant at that general location encountered loose to compact gravel, cobbles and boulders with trace to some silt and sand interpreted to be colluvium, underlain by compact to dense gravelly cobbles to gravel and cobbles with trace to some sand and boulders to 1m diameter. Significant groundwater seepage was encountered in three of their four test pits at depths ranging from 1.2 to 2.3m, suggesting a relatively high groundwater table, especially in the lower elevations of the site. A layer of concrete, found in TP17-07, at a depth of about 0.6m was inferred to be the floor slab of a house that once existed at that location. 4.4 Groundwater Conditions Groundwater seepage was not encountered in the test pits during the time they remained open. There was an observation of elevated moisture content at a depth of about 1.1m at TP17-01 which may have been the remnants of a temporary perched groundwater condition. Anecdotally, the excavator crew carrying out the exploration, who were local to the area, told the exp representative that groundwater springs could be found throughout the area. Due to the relatively high permeability of soils typically encountered in the test pits, and the relatively steep topography of the area, it is likely that the groundwater table is below the zone of interest along much of the alignment. However, as mentioned above, there are areas where the groundwater may be near the ground surface, particularly west of the CP Rail line in the Village of Lytton where the topography is more flat. Further, it appears that there may be the presence of a relatively high groundwater table in the area of the proposed UV chorine facility. Additionally, where low-permeability soils are present, it is possible that zones of perched groundwater may form, particularly during the wet season. 6.0 CONCLUSIONS AND RECOMMENDATIONS 6.1 General Excavations for the watermain installation are expected to extend to a maximum typical depth of about 2.5m. Where the surrounding grade is relatively gentle, excavations can be carried out by sloping the sides of the excavation as described below, or using trench box type shoring. The nearby grade is relatively steep near the easternmost 400m of the proposed alignment, and therefore, trench box or other comparable

type shoring should be used for temporary stability and worker safety purposes. Further comments are provided below. The excavations are expected to be typically dry. However, based on anecdotal information suggesting the presence of localized springs and the inferred elevated moisture condition at TP17-01, groundwater may be encountered in some areas along the proposed watermain alignment, which may be seasonal. Relatively shallow groundwater would be expected near the location of the proposed UV chorine facility per the Piteau report. Excavation below the water table will require dewatering to facilitate installation and backfill in the dry. The type of dewatering will depend on factors such as the time of year of construction, aerial extent of the excavation and the depth of excavation below groundwater and could range from sump pumping to well-point dewatering. Shallowing the pipe embedment and use of pipe insulation for frost protection could be a way to avoid well point dewatering where otherwise required. Details for the groundwater well building and UV chlorine facility have not been provided to exp. Some recommendations are presented below, based on the assumption that the buildings will be relatively light, above-ground structure. If below grade construction is required for these buildings, as mentioned above, dewatering may be required to facilitate excavation. It is understood that trenchless pipe installation would be used to cross beneath the CP Rail Line and Highway 1. The key issue is expected to be the widespread presence of boulders and cobbles in the soil. Further comments are presented below. 6.2 Temporary Excavation Where temporary slopes are considered feasible, they should be planned no steeper than 1H:1V in drained conditions, and follow WorkSafeBC regulations. Flatter slopes up to about 1.5H:1V may be required in areas where caving/sloughing soils and/or groundwater seepage is encountered. For temporary slopes, the face of the slope should be cleared of all overhanging boulders and other loose material likely to slough into the excavation. Where the crest of a sloped excavation would be less than 6m from the toe of an existing slope which is steeper than 2.5H:1V, trench box other comparable type shoring is recommended for temporary stability and worker safety purposes. The watermain alignment should be set so that a trench box system would not encroach with 5m of the toe of existing slope. Where the crest of a sloped excavation would be between 6 and 10m from the toe of such an existing slope, it can be assumed for planning purposes that the excavation could be sloped without the use of shoring if carried out in discreet sections of a maximum length to be determined based on a field review by a geotechnical engineer prior to the start of trench excavation. Restrictions on temporary slopes would generally not be a concern where the crest of the slope is set back at least 10m from an existing slope. With the guidelines provided above, a trench box type shoring should be assumed over the easternmost 400m of the alignment, where the alignment runs along the toe of a relatively steep slope, and the excavation for this shoring system should not encroach within 5m of the toe of the slope. This would likely require the alignment to be located near the edge of the existing roadway on the opposite side of the existing slope. Excavation is expected to encounter frequent cobbles and boulders which may make excavation difficult. Some rock-breaking or possibly even blasting may be required to facilitate the removal of large boulders, particularly when using trench box type shoring.

Excavation below the water table will require dewatering to facilitate pipe installation and backfill or foundation construction in the dry. The type of dewatering will depend on factors such as the time of year of construction, aerial extent of the excavation and the depth of excavation below groundwater, and could range from sump pumping to well-point dewatering. Shallowing the pipe embedment and use of pipe insulation for frost protection could be a way to avoid well point dewatering where otherwise required. Ultimately, the design, operation, and maintenance of the dewatering and shoring system should be the responsibility of the contractor. The contractor will need to determine the means and methods of dewatering necessary to meet the project requirements. 6.3 Design to Prevent Flotation of Manholes or Vaults As mentioned above, anecdotal information suggests that localized groundwater springs have been encountered throughout the area, although not specifically encountered at our test pit locations. Therefore, for static buoyancy design, a groundwater level at ground surface (i.e., full hydrostatic head) is recommended for the design of manholes and vaults. The dead load of the structure plus any permanent equipment, the mass of any overlying fill soil, the mass of soil column engaged by the perimeter area of the foundation slab and the shear resistance of the vertical soil to soil contact surface (a friction coefficient of 0.3 times the vertical effective weight of soil is appropriate) should be used to check the resistance to buoyancy. Further consultation between the Structural and Geotechnical Engineers should be undertaken for this assessment. 6.4 Pipe Foundation and Bedding Based on the interpreted subsoil conditions, it appears that the subgrade at pipe invert level would likely consist of various mixtures of sand, gravel, cobbles and boulders with trace to some silt, with less frequently occurring layers of silty sand to sandy silt also containing varying amounts of gravel, cobbles and boulders, generally in a compact condition. Existing loose granular soils encountered at the pipe subgrade should be re-compacted to at least 95% MPMDD. Due to the cobbly/bouldery nature of the anticipated subgrade soils, we recommend that a minimum bedding thickness of 300mm be allowed for beneath the pipe. After excavating to 300mm below the design pipe invert level, any cavities left by the removal of protruding cobbles or boulders should be infilled with the bedding material and compacted. The bedding material should meet gradation specification for Type 1 “Granular Pipe Bedding and Surround Material” per MMCD Section 31 05 17 Item 2.7. 6.5 Trench Backfill and Pavement Restoration In general, backfill for trenches and excavations should consist of free draining granular soil. Imported backfill may consist of sand 100mm minus pit run sand and gravel, or approved equivalent. Free draining granular soil should have no more than 5% passing the 0.075mm sieve size. The granular backfill should be placed in 300mm loose lifts and compacted to achieve at least 95% Modified Proctor maximum dry density (ASTM D-1557). Note that the existing silty soils are generally not suitable for trench backfill. The existing granular soils may be suitable for re-use as trench backfill provided that particles larger than 150mm size are removed, and subject to the review and approval of the Geotechnical Engineer at time of construction. With the often frequent cobble and boulder content, removal of large particles may not be practical in many areas.

Pavement restoration should conform to MMCD guidelines, and should at a minimum match the existing pavement structure. 6.6 Trenchless Construction To minimize disruption to the CP Rail Line and Highway 1, trenchless construction was to be considered as part of this study. Soils encountered in the test pits nearest these crossings (TP17-04, -06, -07) included sand, gravelly sand, and sandy silt, with boulders and cobbles throughout. The granular soils were noted to be compact, and the upper silt soils were noted to be firm to stiff. Groundwater was not encountered in these test pits. Horizontal Directional Drilling (HDD) and jack and bore methods may be feasible in these soils. Pipe jacking/ramming may not be feasible in these soils due to the presence of frequent cobbles and boulders. Excavation for the entry and exit pits should follow the recommendations for temporary excavations, as discussed in Section 6.2. If shoring is required, a soldier pile and lagging system may be needed due to the coarse nature of the soils that would likely not facilitate a shotcrete and anchor shoring method. These methods require the use of a highly experienced specialty contractor, who would prepare a design-build bid for such work. The contractor should be required to employ techniques that will avoid settlement or heaving of the railway tracks and highway pavement, and this should be confirmed by survey monitoring during installation. They should also be required to employ techniques according to the anticipated ground conditions that will minimize the creation of voids that could cause ground subsidence during or after completion of construction, and should be required to provide adequate warranty against such subsidence, and be responsible for mitigation of any ground subsidence arising as a consequence of their work. 6.7 Building Foundation Design No details regarding the proposed buildings were available at the time of this report; however, it was assumed that the UV chlorine facility and groundwater well building would be relatively light above-ground structures. Based on the Piteau report, the proposed UV chlorine facility area is inferred to be underlain by loose to compact gravel, cobbles and boulders with trace to some silt and sand interpreted to be colluvium, underlain by compact to dense gravelly cobbles to gravel and cobbles with trace to some sand and boulders to 1m diameter. Significant groundwater seepage was encountered in three of their four test pits at depths ranging from 1.2 to 2.3m, suggesting a relatively high groundwater table, especially in the lower elevations of the site. The soils were generally described as compact below about 1.2 to 1.4m. Based on the current test pit TP17-08, the proposed groundwater well building area is inferred to be underlain by silt and sand fill followed by sandy silt with trace gravel and some organics to about 1.2m, underlain by loose to compact sand with some silt which became cobbly/boulder below about 2.7m depth With the inferred subsurface conditions described above, the proposed UV chlorine building may be supported on spread footings founded on loose to compact gravelly/cobbly soils anticipated to be encountered at the design foundation depth. The proposed groundwater well building may be supported on spread footings founded on loose to compact sand soils anticipated to be encountered at design foundation elevation. Due to the cobbly/bouldery nature of the anticipated subgrade soils at the UV chlorine building location, it is recommended that the footings be over-excavated a minimum of 300mm and reinstated with 75mm minus granular structural fill (or 19mm granular base or clear crushed rock) compacted to at least 95% Modified Proctor density. After over-excavating to 300mm below the design footing level, any cavities left

by the removal of protruding cobbles or boulders should be infilled with the same compacted structural fill. It is recommended that the excavated foundation subgrade at the proposed groundwater well building be compacted with suitable vibratory compaction equipment to achieve a minimum 95% Modified Proctor density within at least the top 300mm. Footings supported in the manner recommended above may be designed using Serviceability Limit State bearing resistance of 100kPa and a Factored Ultimate Limit State bearing resistance of 150kPa. For confinement and frost protection purposes, the underside of footings should be placed at least 1.2m below finished adjacent finished grades. Strip and spread footings should have minimum widths of 0.45 and 0.9m, respectively. Using the recommended SLS bearing resistance, it is estimated that the long-term total settlement would be less than about 25mm for footings designed and built as described above. Anticipated differential settlement should be less than 15mm over a horizontal distance of 10m. The exposed subgrade should be reviewed as soon as practical after excavation to confirm the recommended bearing resistance. Loose/soft, organic-rich, disturbed or sloughed materials should be removed from the footing subgrade. Over-excavation of disturbed or loosened materials within the bearing surface may be required as directed by the Geotechnical Engineer. 6.8 Liquefaction Considerations A formal liquefaction assessment was beyond the scope of this study. However, based on the soils data and knowledge of seismicity in the area, it is considered possible that submerged, loose to compact granular soil layers may occur beneath the site that have potential to liquefying during a design 1 in 2475 year return period earthquake event as outlined in the 2012 BCBC. A more detailed investigation using boreholes and/or other methods would be required to substantiate whether or not liquefaction is a concern at this site. The consequences of liquefaction would be significant lateral and vertical ground displacements beneath the site, with corresponding watermain and building movements. Ground improvement techniques would need to be employed to mitigate the effects of liquefaction, which would likely be impractical and cost prohibitive for a project of this nature. Nevertheless, at this point, the Owner needs to accept the risk that liquefaction beneath the site is possible, and if it were to occur, there is potential for the watermain and proposed buildings to be put out of service during a major earthquake event. These risks are likely to commensurate with the existing water system infrastructure within the Village of Lytton. The use of flexible joints and connections would help to reduce the potential for breaks in the system due to ground displacements. Also, tying footings together in both directions or using a monolithic raft slab type foundation would help mitigate potential liquefaction induced impacts on the proposed buildings. 6.9 Subgrade Review and Testing It is recommended that exp be engaged to complete engineering review of site stripping and foundation subgrade preparation, excavation stability and monitoring and testing of backfills during the progress of the work. This will allow for geotechnical aspects of the project to be verified for compliance with the geotechnical recommendations and allow for design changes during construction, as appropriate. 7.0 CLOSURE Please be advised that the contents of this report are based on preliminary information and drawings provided to us and our understanding of the project as described in this report.
