45 GEOTECHINICAL REPORTING

46 November 22, Dalhousie Drive, Kamloops, BC V2C 5Z5 Telephone: Regional District of North Okanagan 9848 Aberdeen Road Coldstream, BC V1B 2K9 Attention: Rod Pleasance, PEng Dear Sir, Re: Geotechnical Investigation of PRV Station #24 Coldstream, BC 1 Introduction and Scope As requested by TRUE Consulting (TRUE) on behalf of the Regional District of North Okanagan (RDNO), Westrek Geotechnical Services Ltd. (Westrek) carried out a geotechnical investigation for the proposed Pressure Release Valve (PRV) Station #24 in Coldstream, BC. The purpose of the investigation was to determine the subsurface conditions at the building site and to provide geotechnical engineering recommendations for the design of its foundations and related matters. The proposed scope was provided to TRUE in an electronic message on October 8 th The project was authorized by RDNO via Purchase Order dated October 9 th TRUE provided preliminary drawings G1 dated October 28 th 2013 for reference. The services provided by Westrek are subject to the terms and conditions set out in the Interpretation and Use of Study and Report and Limitations of Liability, which is attached in Appendix A and incorporated herein by reference. This investigation did not include an environmental site assessment to determine if pollutants are present on the property. 2 Site and Project Description The PRV site is located at the east corner of the Highway 6 intersection with North Aberdeen Road and is bordered on the northeast side by Buchannan Road [Figure 1, attached]. The southeast border is fenced private property (Lot 1 Plan B31800). The proposed site is on an abandoned asphalt road that runs roughly parallel to the fence line. The site slopes gently (6%) to the west and is vegetated with grass, fruit trees and shrubs. The existing PRV station consists of a raised gravel pad and is located approximately 8 m to the southwest of the proposed site. Overhead lines, two utility poles and guy lines are in close proximity to the proposed building. Surface water was not observed in the general area Westrek Geotechnical Services Ltd.

47 R egional District of N orth Okanagan P age 2 of 5 Geotechnical I nvestigation f or PR V Station #24 N ovember 22, 2013 Regional surficial geology mapping 1 indicates that thin glacio-lacustrine deposits are present at the site. The mapping indicates that other pre-fraser glaciation sediments may underlie these deposits. The new building will be a single storey precast concrete building measuring approximately 3.6 by 6.8 m. The conceptual building layout is shown on the attached Figure 2. Following the field investigation, the site plan was updated to show a future addition area on the west side of the building and a gravel parking lot farther to the west. 3 Methodology Westrek supervised the excavation of one test pit (TP-1) adjacent to the northwest corner of the proposed building on November 5 th The test pit location was constrained by existing development and several underground services in the immediate vicinity, including water lines, a gas line, and telecommunications cables. The test pit location is shown on Figure 2. The test pit was excavated with a John Deere 80C tracked excavator that was equipped with a toothed bucket. Surficial deposits were logged and visually classified by a Westrek representative and bulk samples of the surficial layers obtained for further examination and analysis. Soil density was inferred from observing the excavation progress and from pocket penetrometer readings. The conditions encountered in the test pit are provided on the attached log and are summarized below. The surface elevation of the test pit was surveyed relative to two water line valve covers west and southwest of the test pit location. TRUE reported the valve cover elevations to be and m. The test pit was backfilled and compacted with the excavator bucket before leaving the site. 4 Subsurface Conditions Fill comprised of two separate layers of asphalt and road base were encountered in the test pit to a depth of 0.55 m (elevation m). Each of the road base layers were approximately 0.20 m thick and were comprised of compact gravely sand with trace silt to sand and gravel with trace silt. An old topsoil layer was encountered beneath the fill to a depth of 0.70 m (elevation m). The topsoil consisted of dark brown silt with some sand and trace or organic material. It was damp and had a stiff consistency. Below the topsoil was a very stiff, medium brown silt with trace fine sand that graded with increasing depth into a slightly less stiff, light brown silt with some clay and trace fine sand. The lower zone of the deposit is stratified with 1 to 3 cm thick layers separated by millimetre-scale silt/fine sand partings. This deposit extended to the bottom of the 2.9 m deep test pit (elevation m). No seepage was encountered during excavation of the test pit. 5 Discussion and Recommendations A subsurface investigation is a limited sampling of a site that creates a degree of uncertainty in the results, particularly in areas like this where complex glacial deposits exist. Westrek does not represent or warrant that the reported subsurface conditions are consistent throughout the site and users of this information must recognize that variations may exist. Where subsequent observations indicate the subsurface conditions are different from that described in this report, the user should contact Westrek 1 Fulton, R.J.

48 R egional District of N orth Okanagan P age 3 of 5 Geotechnical I nvestigation f or PR V Station #24 N ovember 22, 2013 to review the conclusions and recommendations. This may require additional investigation or lead to additional engineering to meet the project objectives. 5.1 General Geotechnical Considerations The investigation indicated that the site is suitable for the proposed development. A thin layer of fill and buried topsoil was encountered at the test pit location but competent surficial deposits are present at a shallow depth, which will be suitable for supporting the building on conventional strip/spread footings. Groundwater is not expected to be a concern during construction; however, any nearby buried pipe can convey water into excavations following a runoff event. It would also be possible for water to enter the excavation through the old road base structures. If inclement weather is expected, the contractor should have a pump available during foundation construction. Should the excavation become flooded, repair of the foundation soils that become softened or disturbed will be necessary. During excavation of the test-pit, an unknown utility was located approximately 0.5 m below the surface near the north wall of the proposed building. It will likely be encountered during construction of the proposed potable and irrigation lines on the north side of the building. A single stake and ribbon was placed where it was located during the excavation. It is recommended that the function of this underground utility be determined and its orientation within the site located prior to construction. 5.2 Foundation Preparation The uncontrolled fill and old topsoil will not be suitable for supporting the building footings, so it must be removed from beneath the building footprint to expose the underlying silt deposit. If the test pit backfill is encountered during excavation for the proposed building or the future building addition, this should be removed as well. The excavation of uncontrolled fill should be monitored by a geotechnical engineer to ensure the uncontrolled fill is entirely removed, but also to avoid over-excavation. Much of the existing fill on site is expected to be usable as general fill below the floor slab, parking area fill or as service trench backfill. Any deleterious material such as organic material, refuse, cobbles exceeding 100 mm, and saturated or contaminated material must be separated from the excavated fill and disposed of appropriately. Large pieces of asphalt should be broken up prior to use as fill. Suitable material should be stockpiled and protected from weather. The undisturbed surficial deposits have a high silt content, which will soften rapidly if exposed to water. Once the uncontrolled fill is removed and the excavation base is approved by geotechnical personnel, it is suggested that a thin (100 mm) layer of 19 or 25 mm minus crushed gravel be placed on the prepared footing surfaces to protect them during the footing construction process. Alternatively, a skim coat of lean concrete could be used. 5.3 Foundation Design and Construction Footings for heated buildings should be placed at a minimum depth of 1.2 m below grade for adequate frost protection. TRUE indicated that the slab grade will be at an elevation of m. The exterior grade along the east wall is near the slab elevation, but along the west wall it is approximately m. To construct the footing along the west wall on the undisturbed silt deposit, the footing will have to be stepped down or else the exterior grade will have to be raised to achieve adequate frost protection (Figure 3, next page). In the latter case, the footing elevation could be adjusted if it is supported on engineered fill founded on the undisturbed silt deposit. Engineered fill specifications are provided in the following section Westrek Geotechnical Services Ltd.

Slab elevation 6% grade beneath proposed building towards the southwest. Second option is to lower the western footings to achieve minimum 1.2 m embedment depth.

Footings supported on the undisturbed lacustrine deposits or on engineered fill constructed as specified in section 5.4 can be designed using a allowable bearing pressure of 150 kpa 2, based on a minimum burial depth of 1.2 m and a minimum footing width of 0.4 m for strip footings and 0.6 m for square footings. At the above design pressures and footing widths, total and differential settlement should be limited to less than 25 and 20 mm, respectively. The National Building Code requires building design to consider earthquake loading for a return period of 2% probability of exceedance in 50 years, or 1:2475 per annum. The following data was obtained from Natural Resources Canada for this area. The full data sheet is attached in Appendix B. National Resources Canada Seismic Hazard Data 2% probability of exceedance in 50 years (1:2475 per annum) Sa(0.2) Sa(0.5) Sa(1.0) Sa(2.0) PGA (g) Engineered Fill In the event that engineered fill below the building footings is required, it should consist of a wellgraded granular mineral material. Some of the existing fill material on site may be suitable but its volume and consistency is limited. It would be simpler to import a crushed gravel material comprised of well-graded sand and gravel with less than 15% fines (silt and clay). In areas where engineered fill is to be built up to the footing elevation, the fill pad must extend outside the footing edges a distance equal to its thickness of the fill below the footings. Engineered fill should be placed in thin horizontal lifts compatible with the compaction equipment, which is typically 150 to 300 mm. The engineered fill must be compacted to 98% Standard Proctor maximum dry density (SPMDD) as determined using ASTM D698. For efficient compaction the contractor may have to adjust the moisture content of the engineered fill material to within 2 to 3% of the optimal moisture content as determined by Proctor testing. Avoid over-compaction as this could soften the underlying silty soils. Field density testing is required on each lift to confirm that the compaction specification is being achieved. 2 Using working stress design approach Westrek Geotechnical Services Ltd.

50 R egional District of N orth Okanagan P age 5 of 5 Geotechnical I nvestigation f or PR V Station #24 N ovember 22, Fill Below Floor Slab Prior to backfilling the moisture content of the material should be adjusted to within 2 or 3% of its optimum moisture content as defined by the Standard Proctor test [ASTM D698]. Backfill below the floor slab should be placed in 150 to 300 mm horizontal lifts and each lift compacted to 98% SPMDD. If sand and gravel pit run material is imported to the site for this purpose, compaction levels can be reduced to 95% SPMDD. Concrete slabs should be supported on a 200 mm thick base layer comprised of 19 or 25 mm minus crushed gravel. The base course should be compacted to 100% SPMDD. 5.6 Parking Area Due to the presence of fill on site, the entire parking area should be prepared by compaction with a heavy vibratory roller and proof-rolled to detect and soft/loose areas. Any such areas should be investigated and treated. Following preparation, the parking area should be capped with a 150 mm thick layer of clean free-draining sub-base layer containing less than 5% fines, covered by a 100 mm thick layer of 19 or 25 mm minus crushed gravel. These layers should be compacted to 98% SPMDD. 5.7 Construction Review During foundation construction the following geotechnical supervision is recommended. 6 Closure Removal of unsuitable fill from below the building footprint. Excavation of slopes that do not conform to WorkSafe BC regulations. Compaction testing is necessary during placement of engineered fill. Compaction testing is recommended during backfilling below the floor slab including its base. Compaction testing during the backfilling of any service trenches expected to have traffic, including the driveway and parking area is recommended.

61 GREATER VERNON SERVICES 1 GENERAL REQUIREMENTS 1.01 Water Distribution to be Constructed by Applicant All new water distribution works in the GVS water service area, waterworks are to be constructed in conformance with the requirements of GVS. This includes all works on public right-of-way and works in common areas within Strata type developments. Where Developments require the construction of a water distribution system, the Developers shall provide a water distribution system, including watermains, valves, hydrants, service connections, pump stations and reservoirs, consistent with the standards and specifications set out in this Section. All standards not specifically described in this document shall be in accordance with the appropriate American Water Works Association (AWWA) standards and good engineering practices, and installed with good workmanship Approval of Engineering Drawings Required Prior to Construction Engineering drawings that show detailed design of the necessary works shall be submitted to GVS for review prior to the commencement of construction. Depending on the level of technical detail, more than one submission may be required. Submissions for booster stations, reservoirs and other more detailed designs require GVS review as set out in this document. The drawings shall show alignment, size and depths of pipe, pressure class and material, pipe bedding requirements, existing ground line, proposed final ground line over the pipe, location and detail of all fittings, valves and hydrants, location of all service connections, details of any pump stations and reservoirs, all easements and all such other details as may be required. The applicant must also submit detailed engineering drawings to the Public Health Engineer of the Interior Health Authority (IHA). The IHA s approval to construct waterworks shall be submitted to the GVS Water Engineer prior to construction of any water system. No construction shall commence until Greater Vernon Services and the Interior Health Authority have approved the engineering drawings

62 GREATER VERNON SERVICES Where a water system is not yet available, rights-of-way may be required to be provided by the Applicant to allow for the eventual installation of this facility. Such rights-of-way shall be registered in favor of RDNO at the Applicant s expense Use of Relevant Industry Design Standards All standards and specifications related to the design and construction of water distribution systems not specifically described in this section shall be in accordance with the latest edition of appropriate AWWA standard, BC Building Code or Fire Underwriters Survey document. Guidelines followed relating to the design and construction of municipal fire protection systems shall be in accordance with the Fire Underwriters Survey Computer Model Aided Design Greater Vernon Services utilizes a computer model for the design and impact of new development on the existing water distribution systems. For developments greater than 10 residential lots, the computer model shall be utilized by the applicant in assessing on site and off site requirements for water system improvements. The current GVS model is available for use. GVS and/or their consultants will verify the results Works on Private Property Works on private property are the responsibility of the property owner and construction inspection and installation will be reviewed as part of the Building/Plumbing inspection Strata Developments Standards for works on strata developments are to follow the standards within this document. To conform with our Cross Connection program, a double check valve is required at the property line to isolate the strata from the water system. The double check valve is typically located in the meter pit or a separate pit. Works that will become part of the GVS system are subject to inspection before, during, and subsequent to construction. Only one water system connection is permitted to a strata development. Loops to interconnect to the GVS distribution system are not permitted, unless approved in writing by the GVS Water Engineer

63 GREATER VERNON SERVICES 2 DESIGN CRITERIA 2.01 Applicable Service Area Design standards for water systems in the GVS service area will vary, depending on geographical location and the availability of water. Two areas are defined as follows: Rural Areas: areas with a housing density equal to or lower than 1 unit per 2 hectares Urban Areas: areas with a housing density higher than 1 unit per 2 hectares Two design conditions exist: 1. Single Water System Areas: For areas such as the Vernon city core area, where only one watermain will be required for installation within the road right of way. The watermain is to provide water for all uses including domestic service, irrigation and fire protection; 2. Separated Water System Areas: Areas where two or three water distribution system mains exist. Developer must design and install both irrigation and domestic service mains. The domestic mains are to provide water for all indoor purposes and in some cases, as specified by GVS, for fire protection. The water will be treated to a high quality standard. The irrigation watermain is to supply water for all outdoor uses and provide water for fire protection; For a location of which design condition applies, GVS will provide direction on the design condition and whether single system or separated system conditions apply Capacity of System and Sizing of Watermains Water distribution systems shall be designed to deliver water in adequate quantities and at adequate pressures for both domestic use under peak consumption conditions, and fire flows. For single system areas, where the distribution system provides both irrigation and domestic water, the capacity must be sufficient to meet the pressure and quantity requirements. Mains shall be sized to carry the greater of the peak hour flow rate or, the maximum day plus fire flow rate

64 GREATER VERNON SERVICES Where dual distribution system exists, the domestic water system must meet instantaneous peak demand. The irrigation system must provide maximum daily demand for all uses other than indoor domestic service, plus fire flow. Mains shall be sized using the Hazen-Williams formula with the friction coefficient C equal to 130 for PVC pipes, equal to 125 for Ductile Iron (DI) pipe, equal to 140 for polyethylene pipe and equal to 150 for Pre-stressed concrete cylinder pressure (PCCP) pipe. The maximum velocity for the peak hourly demand rate shall not exceed 2.0 m/s for pipes with diameter equal or higher than 250mm; for pipes with diameter lower than 250mm the maximum flow velocity under peak hourly demand shall not exceed 2.5 m/s. For fire flow plus the maximum day rate, the maximum velocity shall not exceed 4.0 m/s Water Demand Criteria Population density shall be calculated using 3.0 persons / single family residential unit and 2.0 persons /multi-family unit. For residential areas with an average lot area of 0.2 ha. and smaller, the daily demand criteria for a water system supplying both irrigation and domestic water to residential developments shall be as follows: Average Daily Demand = 700 L/ca/day Maximum Daily Demand = 1,800 L/ca/day Peak Hourly Demand = 1.5 times Maximum Daily Demand For residential areas with an average lot area greater than 0.2 ha, an additional design demand of 0.8 L/s/ha shall be added to the base design water demand. For residential areas with a separate domestic system, the criteria for supplying domestic water to residential developments for all indoor uses shall be as follows: Average Daily Demand = 400 L/ca/day Maximum Daily Demand = 500 L/ca/day Peak Hourly Demand = 2.5 times Maximum Daily Demand For areas other than residential, the demand criteria shall be selected to suit the particular circumstances subject to the approval of GVS. Institutional and commercial flows shall be estimated based on historical records, where available

65 GREATER VERNON SERVICES For commercial areas, an allowance of 28 m 3 /ha.d average flow shall be used in the absence of reliable flow data. For institutional and commercial demands, an assessment of the water using fixtures is necessary and a fixture-unit approach shall be used. Industrial water demands shall be expressed in terms of water requirements per hectare when the type of industry is unknown. Allowances for industrial areas are as follows: Light Industrial Heavy Industrial 35 m 3 /ha.d 55 m 3 /ha.d When the type of industry is known, discussions should be held with representatives of the industry to determine water requirements. Water demand for agriculture and sports fields shall use the maximum daily rate of (0.8 L/s).ha for the property area Fire Demand Criteria Water distribution systems shall also be designed to ensure that fire flow, as required by the Insurers Advisory Organization (IAO), is available for the required duration. Fire flows shall be in accordance with the Fire Underwriters Survey (FUS) as a minimum. The following minimum fire flows must be met for the noted zones under Maximum Day Demand condition, the greater of these two standards will apply. ZONE Single Family Units Low Medium Density Residential Light industrial, Commercial High Density Residential Industrial MINIMUM REQUIRED FIRE FLOW 60 L/s 90 L/s 90 L/s 150 L/s 200 L/s Please note that the flows presented are the flows required in the watermain to which the hydrant is connected. The designer shall provide the flow volume and duration of the design fire flow to GVS for approval prior to final design of the water distribution system

66 GREATER VERNON SERVICES An Engineer sealed FUS calculation flow sheet shall be provided for the proposed development. Format of the calculation sheet should be in accordance with the example Fire Flow Calculation sheet included (at end of document). If the water distribution system is split to provide separate irrigation and domestic service, fire protection must be available from one of the water systems to meet IAO requirements at all times of the year. Fire sprinkler systems shall be allowed, however only where the water system has sufficient size and capacity. The design must provide details for the service pipe, connection size to the watermain and sprinkler system flow and pressure requirements Design Pressures For all new development areas, water systems shall be designed for pressures in the range of 300 kpa, (44 psi) to 900 kpa, (130 psi), with 300 kpa (44 psi) measured under peak hourly conditions and 900 kpa (130 psi) measured under static conditions. The minimum pressure shall be measured or calculated at the main floor building elevation of the highest proposed structure with an allowance made for pressure loss in the service line to the building wall. Building envelopes, with specified main floor elevations, are to be identified as part of the development design for any lots that may be near the service limits for the water system to site structures in serviceable locations. Minimum residual pressure in the water system shall not be less than 140 kpa (20 psi) under maximum day demand plus fire flow conditions or peak hour conditions. Reservoir level shall be assumed at mid point for calculation of minimum pressures and full for calculation of maximum static pressures. Transmission pipes shall be designed for a maximum operating pressure of 1,550 kpa (225 psi) not including hydraulic transient pressures, unless otherwise approved by GVS Minimum Pipe Size The minimum pipe size must be verified by the applicant s engineer, but in all cases must not be less than 150mm diameter. The pipe size may be reduced beyond the last fire hydrant in areas of one directional flow where no future looping of the system will occur

67 GREATER VERNON SERVICES 2.07 Location and Grade of Watermains For renewal works, the standards below shall be followed unless modifications are required due to existing constraints. GVS must approve any deviation from the standards. For new development areas, there shall be a minimum horizontal clearance of one metre [edge to edge] between watermains and any other existing or proposed surface or underground services e.g. power poles, shallow utility boxes, etc. A minimum of three metres horizontal distance on centerline, between a watermain and a sanitary sewer main or storm sewer main, shall be maintained. In special cases such as replacement of existing works where adequate separation cannot be provided the horizontal clearance may be reduced, with the approval of GVS, provided the invert of the watermain is a minimum of 450 mm above the top of the sanitary sewer, pressure class pipe shall be used for the sanitary sewer, and the installation meets any other regulations in place at the time. On side-hill streets, the watermain shall, where possible, be located on the cut side of the centerline of the street in native soils. For dual distribution systems, domestic and irrigation lines must have a 3.0m horizontal separation unless otherwise approved by GVS. Watermains shall be normally designed to follow a straight horizontal alignment between intersections and at a vertical alignment parallel to the road centerline. Curved alignments may be accepted provided that the pipe alignment is at a parallel offset with an established boundary and the radius of curvature is not less than 60 m or the minimum radius of curvature recommended by the pipe manufacturer, whichever is the greater. The design drawings shall indicate where any short pipe lengths are proposed on curves. Watermains shall be designed to minimize high points in the main. Careful grading can eliminate high points. However, where a high point is unavoidable, a hydrant, blow off, or combination air/vacuum release valve shall be installed at that point. Where the watermain network is weak, interconnection or looping of the water system will be required and may necessitate the provision of rights-of-way in favor of the RDNO. No gas main, electric, telephone duct or other utility line shall be installed in the same trench with watermains

68 GREATER VERNON SERVICES Where it is necessary for the watermains to cross other underground services, the crossing shall be made at a horizontal angle greater than 20 degrees and the vertical clearance between services at the crossing point must be in accordance with Interior Health Authority requirements. Vertical clearance shall be not less than 150 mm except in the case of sanitary sewers or storm sewers where the clearance shall not be less than 450 mm between the exterior walls of the pipes, unless approved in writing by GVS. The drawings shall indicate all crossings with other underground services Fire Hydrants Fire hydrants shall be constructed as shown on Standard Drawing W-04. Hydrants shall be plumb and shall have their nozzles parallel with or at right angles to the curb. Hydrants shall be set with ground flange above the ground at the elevation directed by GVS generally at 150 mm above finished grade or curb grade where available. When set in a permanent sidewalk or other solid structure, a suitable expansion joint material shall be placed around the hydrant to allow for movement between hydrant and structure. All hydrants shall be supplied with drains unless otherwise specified by GVS. Sufficient drain rock shall be placed to allow for proper hydrant drainage, generally a minimum of 0.25 cubic metres. In general, fire hydrants shall be located at road intersections and at spacing in accordance with flow requirements based on the Tables in the FUS guidelines or at maximum spacing as follows: Residential Areas High Density and Commercial Rural areas Urban-wildland interface area 150 m 90 m 300 m (or greater if permitted by GVS) 150 m Additional hydrants may be required by GVS at schools, major multiple family developments, commercial or institutional buildings, or other major developments consistent with the latest fire flow requirements of the IAO and the current building code. Additional hydrants shall match the existing fire hydrants whenever possible. The additional hydrants must be selected from an approved product list

69 GREATER VERNON SERVICES Where hydrants are located away from intersections, they should be located on the projection of the property line dividing two lots. In selecting the location of a hydrant, the probable route of the fire truck shall be considered.

80 GREATER VERNON SERVICES 4 WORKMANSHIP Works shall be carried out in accordance with the Master Municipal Construction Documents. Works in the GVS shall meet requirements of the MMCD specifications. Special provisions are as follows: 4.01 Trench Excavation Trenches shall be excavated to suit the cross-section shown on the Standard Drawing W- 09. Open trenches through existing paved surfaces will be allowed only with the prior express consent of GVS. When trenches through existing pavement are allowed, the pavement shall first be saw-cut by mechanical means in straight continuous lines parallel to the trench centreline. The top of the trench at ground level shall be kept to the minimum width consistent with the depth, natural angle of repose of the material and the regulations of the Workers Compensation Board. Excavation for manholes, fittings and other appurtenances, shall be to the lines, which will permit the assembly of these sections. Concrete for bases may be cast against the walls of the excavation, if the soil conditions are suitable. Where an existing structure or underground installation may be affected by the works, it is the responsibility of the Developer to inform GVS of such facility sufficiently in advance that GVS may make an inspection and specify the protective measures to be undertaken. Where an unforeseen or other obstruction is encountered which interferes with the designed alignment or grade, the construction shall cease until such time as GVS approves revised proposals. The attention of the Developer is directed to the provisions of the Workers Compensation Board safety regulations. Approvals cannot be given to installations not inspected because of unsafe working conditions. In rock excavation the depth of compacted bedding material below the pipe shall be a minimum of 150 mm for pipe of 600 mm diameter or less and 250 mm for pipe in excess of 600 mm diameter. This depth shall exist for the full wall-to-wall width of the trench

81 GREATER VERNON SERVICES Where the bottom of any excavation as uncovered is soft and is in the Design Engineer s opinion unfit to support the pipes or structures, a further depth shall be excavated and refilled to the correct shape, grade and elevation as directed by the Design Engineer. When the bottom of a trench is found to consist of unstable material, which, in the opinion of the Design Engineer, cannot be removed and replaced with bedding material, a pile foundation or other structural support in accordance with plans prepared by the Design Engineer shall be constructed. In areas of clay or other impermeable soils, where over-excavation of the trench subgrade is required, the over-excavation shall continue to a point where pending of water in the trench bottom will be avoided. Open cut trenches shall be sheeted and braced as required by the Workers Compensation Act, as may be necessary to protect life, property, or the work, unless the trench excavation is sufficiently wide at the top to be naturally stable. When close sheeting is required, it shall be driven so as to prevent the soil from entering the trench either from below or through such sheeting. A minimum distance of 150 mm from the closest point of the pipe to the sheeting shall be maintained. When possible, vertical trench timber or sheeting shall be placed so that it does not extend below the level of the bottom of the excavation. Sheeting driven below the pipe grade shall not be removed unless the sheeting can be removed without causing settlement or lateral displacement of the pipe. Sheeting thus left in shall be cut off 100 mm above the top of the pipe. Unless otherwise indicated in the drawings or specifications, or unless approval to leave it in place is received from GVS, trench sheeting and bracing shall be removed when backfilling has been completed or has reached a level, which will permit its safe removal without causing injury to persons or damage to the works. Particular caution will be taken to ensure that pipe bedding is not disturbed such that settlement of the pipe results. When sheeting and bracing is left in place, it shall be cut such that no sheeting remains closer than 1 metre to the established sub-base road grade or the existing ground surface, whichever is the lower. Timber supports or sheeting shall be left in place when its removal would endanger adjacent structures or result in a shifting of pipe bedding material and a displacement of the pipe. GVS

82 GREATER VERNON SERVICES may require the pipe to be bedded in concrete (Class A Bedding) when, in his opinion, the removal of sheeting would disturb the pipe bedding Bedding Class The quality of the bedding shall be so selected such that the installation will adequately support the loads to be placed on it during construction and in operation. For PVC pipe, the calculations shall follow the methods outlined in the latest edition of the Uni- Bell Plastic Pipe Association publication Handbook of PVC Pipe - Design and Construction. For ductile iron pipe, the calculations shall follow the method shown in the latest edition of CSA B For all pipe, minimum Class B bedding, as defined by Standard Drawing W-10, is required. Pipe class and bedding class must be identified on all engineering drawings Pipe Installation Works shall be carried out in accordance with the Master Municipal Construction Document and shall meet requirements of the MMCD specifications. The grade of every pipe length shall be checked before the pipe is backfilled. Any part of the trench excavated below grade shall be regraded with approved material thoroughly compacted. All pipe must be laid to the design lines and grades within the following tolerances: horizontal and/or vertical deviation from the approved alignment shall not exceed 60 mm; the rate of deviation shall not exceed 40 mm in 10 metres Backfill in Pipe Zone Works shall be carried out in accordance with the Master Municipal Construction Documents. Works shall meet requirements of the MMCD specifications. Special provisions are as follows: The pipe zone is considered as being the depth of trench between the trench bottom and a level 300 mm above the top of the pipe. Backfill from 50 mm above the springline of the pipe to the top of the pipe zone cover shall be with the same material as used for pipe bedding material. The pipe zone backfill shall be hand placed and thoroughly compacted to a density of 95% Standard Proctor Density in layers not

83 GREATER VERNON SERVICES exceeding 150 mm using hand tampers around the pipe to spring line. Mechanical means to compact the layers are to be used below and above the pipe zone Backfill Above Pipe Zone in Road Areas Works shall be carried out in accordance with the Master Municipal Construction Documents. Works in the GVS shall meet requirements of the MMCD specifications. Special provisions are as follows: The water content of the material shall be controlled to achieve the required density. When the natural water content of the material is less than the required value, water shall be added during the placing of the fill materials. When the water content of the material is greater than the required value, all compaction and placement operations shall cease and the material removed and new material used Backfill Above Pipe Zone in Non-Road Areas Works shall be carried out in accordance with the Master Municipal Construction Documents. Works shall meet requirements of the MMCD specifications Temporary Water Temporary water can be provided during local construction either from a hydrant or a home service, but only after approval of GVS, which will install a backflow preventor and meter. Unauthorized use of water from hydrants or services is otherwise considered theft and subject to prosecution Flushing Flushing of the pipeline shall be performed on all installed piping according to AWWA Standard C605. Special provisions are as follows: The pipe shall be cleaned of dirt and other foreign materials. The pipe shall be flushed at minimum water velocities of 1 m/s. Flushing time shall be at least five times the time required to travel the entire main at the flush velocity. Flushing shall continue for the required time, or until 10 minutes after the discharged flushing water turbidity is consistent, whichever is greater. If the discharge water is to be released into a watercourse, storm drain, or body of water, then it shall be treated to reduce the concentration of Total Residule Chlorine (TRC) below the levels established by the Government of British Columbia Ambiant Water Quality Criteria for Chlorine

84 GREATER VERNON SERVICES At no time shall water from the GVS community water system be released into the environment with a TRC concentration greater than 0.1 mg/l. Under normal operating conditions, the concentration of TRC in GVS drinking water is typically within the range of 3.0 mg/l to 0.2 mg/l Leakage Tests Following final trench backfilling and flushing, leakage tests shall be performed on all installed piping according to MMCD and AWWA Standard C600. Tests shall be conducted in the presence of GVS with a 2 working day notice provided to GVS in advance of the test. A leakage test shall be conducted after all mains and service connections have been completely installed and backfilled. The Developer shall furnish all necessary apparatus, test water and labour to conduct test. Leakage tests shall be not performed in accordance to MMCD specifications. Leakage test shall not be performed against a valve in the existing water distribution system. The section to be tested shall be filled with water and all air expelled from the piping. It is recommended that the test section be filled with water for at least 24 hours prior to testing. By pumping water into the test section, the pressure within the piping shall be increased to the pressure rating of the main (usually 1050 kpa or 1 ½ times the operating pressure), whichever is greater. This pressure shall be maintained constantly in the pipe throughout the duration of the test by the addition of make-up water. The duration of the test shall be a minimum of 2 hours. Hydrant leads shall be shut off at the hydrant such that the hydrant is placed under test. The quantity of water pumped into the test section to maintain the specified pressure over the period of the test shall be considered to be the leakage. Watermains will not be accepted until the leakage is less than the maximum allowable leakage, which shall be calculated by the following formula: Where: SD P L = 715,317 L = the allowable leakage in L/hr S = the length the test section, in metres D = the nominal diameter of the pipe in mm P = the average test pressure during the leakage test in kpa Should any test disclose leakage greater than that specified above, the source of the leakage shall be located and the defect repaired or the necessary replacement made and the section reflushed, and then retested until a satisfactory test is obtained. All repairs to the work shall be made with

85 GREATER VERNON SERVICES new material equivalent to that requiring repair or replacement. The use of repair and maintenance aids, such as clamps will not be permitted. Leakage tests shall be carried out between valved sections of the installation such that every valve in the system is tested for leakage in the shut-off position Disinfection Works shall be carried out in accordance with the Master Municipal Construction Documents. Works in the GVS shall meet requirements of the MMCD specifications and AWWA Standard C651. Special provisions are as follows: No pills, powders or solids shall be placed in the main during installation or for chlorination purposes. Chlorination shall be applied by the continuous feed method. The chlorine solution shall be injected at a measured rate such as to fill the main with a minimum 50 mg/l available chlorine solution. All appurtenances shall be operated in this solution to disinfect them. All measures shall be taken to prevent the disinfectant solution from flowing into existing water supply system. The disinfecting solution shall remain in the main for 24 hours and shall have residual greater than 25.0 mg/l at the end of that period. Following disinfection of lines to the required standard, the line shall have a final flushing to completely purge all disinfecting solution. If the discharge water is to be released into a watercourse, storm drain, or body of water, then it shall be treated to reduce the concentration of Total Residule Chlorine (TRC) below the levels established by the Government of British Columbia Ambiant Water Quality Criteria for Chlorine. At no time shall water from the GVS community water system be released into the environment with a TRC concentration greater than 0.1 mg/l Bacteriology Prior to acceptance of the domestic water system, the developer shall submit samples of disinfected water to a certified testing laboratory for verification of disinfection and a log of all test results and disinfection procedures shall be submitted as a portion of the water system completion report, to GVS. A GVS inspector shall be present and witness the water sampling. The sample bottle shall be sealed and the GVS inspector shall sign the sample bottle container. After acceptable lab results have been received, the entire piping system shall be thoroughly flushed, filled with water and left in a condition ready for use

86 GREATER VERNON SERVICES 4.12 Compaction Tests Compaction testing of all trench backfill works shall be performed at the expense of the Developer. Frequency of compaction testing for trench backfill shall be one test per lift per 100 lineal metres of trench or as otherwise specified by the Design Engineer on the detailed design drawings. Copies of all trench backfill compaction test reports shall be bound within the certification report for presentation to GVS on completion of the works. The Developer shall retain the services of an independent materials testing firm to carry out comprehensive testing of all materials. Control tests shall include material sieve testing and laboratory density testing. One sample per 100 lineal metres is required.
