This report presents the results of the geotechnical investigation carried out
by Forward Engineering & Associates Inc. for the proposed parking lot
pavement at Bramalea Secondary School located at 510 Balmoral Drive, in
the City of Brampton, Ontario.
The location of the proposed parking lot in relation to the existing school
building and surrounding roads is shown on Drawing No. 1. The locations of
the boreholes carried out during this investigation are also presented on
Drawing No. 1.
This investigation was authorized by Mr. Kevin Lilliman, of Moffet and
Duncan Architects on behalf of Peel District School Board.
PURPOSE AND SCOPE
The objectives (purpose) of this investigation were to determine the
The extent, depth and properties of the predominant fill/soil strata, as they affect the design and construction of the proposed pavement.
The short term groundwater levels, if encountered
The required design criteria for utilities and pavement design at the proposed new parking lot.
To achieve the above noted objectives, the field program consisted of drilling
six  boreholes sampled to a maximum depth of 3.15 m below ground
On completion of the field and laboratory work, an engineering analysis was
carried out and this summary geotechnical report was prepared.

We understand that the proposed work will consist of a new asphalt and
concrete pavement in the north east corner of the existing school building
where landscaping currently exists. Concrete walkways and landscaping are
proposed at the remaining areas of the site.
FIELD AND LABORATORY TESTING
The field work for the borehole investigation consisted of six  boreholes
(BH-1 to BH-6) drilled on November 03, 2017, under the full supervision of
a member of our staff.
The drilled boreholes were located at the approximate locations shown on
Drawing No. 1, and extended to a maximum depth of about 3.15 m below
Existing Ground Surface Level (EGSL). Some of the boreholes were
relocated in the field from originally intended/planned location due to
existing underground utility services and existing landscape features.
Soils were sampled in the boreholes following the Standard Penetration Test
(SPT) method. The samples were logged in the field and appropriately stored
in plastic bags and re-examined in more detail in the laboratory.
The samples will be stored for a period of three months and then discarded,
unless we are instructed differently.
Groundwater observations were made in the open boreholes, during and upon
completion of the drilling operation. The results are recorded on the Log of
Elevations referred to in this report are metric and geodetic. The ground
level elevations at the borehole locations were interpolated from the Plan of
Topography dated November 11, 2010, conducted by Tarasick McMillan
Kubicku Ltd., and provided to us by the client.

Laboratory testing consisted of determination of the in-situ moisture content
of the retrieved and representative soil samples.
Bramalea Secondary School is located at 510 Balmoral Drive, in the city of
Brampton, Ontario. Currently the school is operational. For the purpose of
this investigation it will be assumed that the north bearing is parallel with
The subject site (the area of the proposed parking lot), where the borehole
investigation took place, is located at the north east corner of the existing
The subject site conditions, as observed during our site visit on November
03, 2017, is presented in the following Table;
East Boundaries: Bramalea Road, followed by institutional
building (Church of God offices).
North Boundaries: Soccer Field/running track followed by
West Boundaries: Balmoral Drive, followed by multi-storey
South Boundaries: School building, followed by residential
Surface Coverage: Surface of the subject site is predominantly grass
landscaping with mature trees and with areas of
asphalt pavement and concrete walkways.
Ground Level: Generally flat, with a minor overall slope grading
down in the north and east directions.
Existing Structures: 1 and 2 storey brick structure with no basement.

The sub-surface conditions encountered at the borehole locations are
shown on the Logs of Boreholes, presented in Appendix A, and can be
summarized as follows:
Topsoil/Organic Soil A layer of topsoil (organic soil), with a
thickness ranging between 100 and 200 mm, was encountered at the
surface of all the boreholes.
Reworked/Disturbed Soil Reworked/disturbed soil was encountered below the toposoil/organic soil layer in all the
boreholes, and extended to a depth ranging from about 0.30 to 1.60
m below ground surface level (EGSL). This brown layer consisted
of sandy and clayey silt with traces of rootlets, stains to traces of
organics and occasional traces of gravel. This disturbed soil layer
was found in compact state of packing and in moist condition.
Silty Clay Till/Clayey Silt Till Very stiff to hard silty clay till/clayey silt till was encountered below the reworked/disturbed soil
layer and extended to a depth of about 2.3 m below EGSL in
boreholes BH-2 and BH-3, or to the maximum depth of this
investigation. This olive brown and moist till contained occasional
Highly Weathered Shale Hard, grey and moist highly weathered shale was encountered below the silty clay till/clayey silt
till in boreholes BH-2 and BH-3, and extended to the maximum
depth of this investigation. For estimate purpose, in areas where the
boreholes did not extend into the shale, shallow bedrock should be
expected to start from the bottom of the boreholes.
Groundwater All the boreholes remained open and dry upon the completion of the drilling operation, except for borehole BH-1,
which remained open and the water level was measured at a depth of
3.0 m (i.e. about 70 mm of water at the bottom of borehole).
The water level at borehole BH-1 was most likely the result of soaked
topsoil layer, with surface water slowly seeping into the borehole.

It should be noted, however, that the groundwater levels are subject
to seasonal fluctuations. Consequently, definitive information on the
long term groundwater levels could not be obtained at the present
