StantecGeotechnical InvestigationCity of Winnipeg Street Investigation1.0IntroductionAt the authorization of Mr. Mark Edgar, P. Eng., of Stantec, Wood Environment & Infrastructure Solutions,a division of Wood Canada Limited (Wood), completed a pavement coring and test hole drilling programrelated to the pavement evaluation and potential asphalt reconstruction and rehabilitation for thirty (30)locations in the City of Winnipeg, Manitoba. Locations and scope are itemized in Table 1-1. In summary,the Scope of Work included the coring of the pavement surface at a total of twenty street locations, withthe advancement of test holes to a minimum depth of 2.5 m at fifteen of those locations. At the remainingfive coring-only locations, a total of three cores were obtained, one from mid-slab, one from thetransverse joint, and one from the longitudinal joint.Table 1: Street Location and Investigation ScopeStreet NameSalter StreetSelkirk AvenueWilliam AvenueLocationSlaw Rebchuk Bridge toCathedral AvenueMcPhillips Street toArlington StreetMcPhillips Street toArlington StreetTotalNumberof CoresNumber ofTest HolesTest Hole Numbers183TH20 - SS01 to TH20 - SS03CH20 – SS04 to CH20 – SS0877TH20 - SA01 to TH20 - SA0755TH20 - WA01 to TH20 – WA053015The geotechnical investigation was completed in accordance with the Scope of Work and Terms andConditions outlined in Wood Proposal No. WPG2020.269, dated 6 May 2020.2.0Geotechnical InvestigationPrior to initiating drilling, Wood notified public utility providers (i.e. Manitoba Hydro, MTS, Shaw, etc.) ofthe intent to drill in order to clear public utilities, and where required, met with said representatives onsite.Between 22 May and 3 June 2020, Wood supervised the drilling and coring a total of thirty core holes andfifteen test holes distributed between Salter Street, Selkirk Avenue and William Avenue as indicated inTable 1-1. The test hole locations are illustrated in Figures A1, B1 and C1. All locations were cored using a150 mm diameter core barrel, while test hole drilling was conducted using a truck mounted Mobile B40LXor CME85 drill rig equipped with 125 mm solid stem augers, owned and operated by Maple Leaf Drillingof Springfield, Manitoba. Coring and test hole locations were initially selected by Stantec, howeverunderground utilities required some adjustments to the original test hole locations. All final test holelocations were provided to Stantec prior to coring or drilling. At core-only locations (CH20-SS04 to CH20SS08), a total of three cores were obtained, one at mid-slab (identified as core “A” at each location), one atthe transverse joint (identified as core “B” at each location), and one at the longitudinal joint (identified ascore “C” at each location).During coring, Wood field personnel identified pavement types and thicknesses, as well as underlyinggranular structure, while during drilling, Wood field personnel visually classified the soil stratigraphywithin the test holes in accordance with ASTM D3282 and ASTM D2487, as well as noted observedseepage and/or sloughing conditions. Soil sampling consisted of grab samples of the auger cuttings at allWX19092 June 2020

StantecGeotechnical InvestigationCity of Winnipeg Street Investigationtest hole locations. All grab samples were retained in sealed plastic bags and shipped to Wood’sWinnipeg laboratory for review and selected testing. All pavement core samples were shipped toWinnipeg laboratory to be photographed. The core photos and underlying pavement structureinformation are provided in Appendices A, B and C for Salter Street, Selkirk Avenue and William Avenue,respectively.During drilling, Wood field personnel visually classified the soil stratigraphy within the test holes inaccordance with ASTM D2487 – Standard Practice for Classification of Soils for Engineering Purposes andrecorded observed seepage and/or sloughing conditions. Soil sampling consisted of grab samples of theauger cuttings at all test hole locations at depths of 0.6 m, 0.9 m, 1.2 m, 1.6 m, 2.0 m, and 2.5 m.Additionally, bulk samples were collected of the anticipated subgrade soils on which pavements would beconstructed, beginning at a depth of about 0.9 m or deeper where soils expected to require excavationprior to pavement construction were observed at or below this depth. Test holes were advanced to adepth of about 2.6 m, except for TH20-SA05 and TH20-SA06, which were advanced to about 3.7 m as perrequest from Stantec. The in-situ relative consistency of cohesive soil (i.e. clay) was evaluated duringdrilling using a pocket penetrometer. All samples were retained in sealed plastic bags or within the ShelbyTubes and shipped to Wood's Winnipeg laboratory for review and selected testing.Following completion of the field drilling program, a laboratory testing program was conducted on all soilsamples obtained from the test holes. The laboratory testing program consisted of moisture contentdeterminations on all samples, as well as Atterberg limits, particle size distributions (hydrometer method),Standard Proctor Testing in conjunction with California Bearing Ratio (CBR) evaluations on the anticipatedsubgrade soils. Results of the subgrade soil detailed testing are shown on the test hole logs at a nominaldepth of 1.1 m, or deeper where soils expected to require excavation prior to construction were found. Itshould be noted that all the above testing has been completed with the exception of CBR testing. CBRresults will be provided upon their completion. Laboratory testing results and detailed test hole logssummarizing the sampling, field testing, laboratory test results, and subsurface conditions encountered atthe test hole locations are presented in Appendices A, B and C for Salter Street, Selkirk Avenue andWilliam Avenue, respectively. Actual depths noted on the test hole logs may vary by 0.3 m from thoserecorded due to the method by which the soil cuttings are returned to the surface. Summaries of theterms and symbols used on the test hole logs and of the Modified Unified Soil Classification System arealso presented in Appendix A.3.0Pavement SummaryThe following sections provide summaries of the pavement structure encountered at each test hole andcore hole location. Details of the soil structure underlying the pavements observed either at the bottom ofeach core hole or within the test holes can be found on the test hole logs or core photos found inAppendices A, B and C.3.1Salter StreetTable 2 provides a summary of the pavement type and thickness encountered at each of the test locationson Salter Street.WX19092 June 2020

Although no environmental issues were identified during the fieldwork, this does not indicatethat no such issues exist. If the owner or other parties have any concern regarding the presence ofenvironmental issues, then an appropriate level environmental assessment should be conducted.Soil conditions, by their nature, can be highly variable across a site. The placement of fill and priorconstruction activities on a site can contribute to the variability especially near surface soil conditions. Acontingency should always be included in any construction budget to allow for the possibility of variationin soil conditions, which may result in modification of any potential design and construction procedureswhich may arise from this factual investigative report.This report has been prepared for the exclusive use of Stantec, and their agents, for specific application tothe project described in this report.
