1.0 INTRODUCTION
1.1 BACKGROUND
Harder Associates Engineering Consulting Inc. (Harder Associates) was retained by
CJP Architects Ltd. (CJP) on behalf of the Northern Rockies Regional Municipality
(NRRM) to conduct a geotechnical assessment and provide foundation and floor
recommendations, based on a previous report, for a washroom addition to the
Terminal Building at the Fort Nelson Airport. The site is located approximately 7.5
kilometres northeast of Fort Nelson, British Columbia.
The proposed single storey addition, washroom facilities, proposed to be constructed
on the north side of the existing Terminal Building, have a proposed footprint of 72.5
m 2 . Due to the small footprint and possible temporary (a new terminal building is
being discussed) nature of the addition, the client requested foundation and slab
recommendations without performing a geotechnical investigation. Therefore, the
recommendations provided in this report are based off a third party geotechnical
investigation performed in 2004.
Harder Associates cannot verify the authenticity of the third party report or that the
subsurface soils in the proposed addition footprint will be similar to those
encountered during the geotechnical investigation.
1.2 OBJECTIVES
The objectives of the geotechnical assessment were to:
provide geotechnical recommendations for cast-in-place concrete piles,
screw piles, and concrete footings; and,
provide geotechnical recommendations for floating and structural floor
slabs.
2.0 REVIEW OF PREVIOUS REPORTS
Harder Associates personnel reviewed a report provided by CJP personnel, written by
J.R. Paine & Associates Ltd. titled “Geotechnical Investigation, Light Standard
Supports, Fort Nelson Airport, Fort Nelson, B.C.”, dated April 2004, File No.

GP6132-2. A brief summary of the information obtained from the referenced report
is as follows:
Three boreholes were drilled between the terminal building and apron on 05
April 2004. The maximum depth of exploration was 9.5 m.
Surficial topsoil and asphalt were encountered overlying silty sand and clay
till. The clay till extended to the maximum exploration depth in all three
boreholes.
Seepage was encountered in boreholes BH04-1 and BH04-2 but no sloughing
was encountered during drilling.
The referenced report is included in Appendix A.
3.0 FOUNDATION RECOMMENDATIONS
There is more than one suitable option for the type of foundation system used
however, most foundations systems mobilize their full support and behave
differently. Therefore, the use of several different types of foundations systems to
support the same structure is not recommended. It is recommended that the same
type of foundation supporting the existing terminal building is used to support the
proposed addition.
3.1 SCREW PILES
Lighter foundation loads may be supported by screw anchors. Frost jacking is not an
issue for screw anchors; however, the helix plates/plates must be completely below
the depth of frost penetration, estimated to be 2.5 m at this site.
The desirable depth for screw anchors is 4.5 m. The design for screw anchor piles
having a steel shaft diameter of 127 mm (5 inches) and a helix diameter of 457 mm
(18 inches) is calculated using the following: 1
h h u c h q 0.5 y
1 Canadian Geotechnical Society, 2006. Canadian Foundation Engineering Manual 4 th
Edition, p. 267.

File No.: FN321
Page 3
Where:
h = Individual helix bearing capacity;
h = Projected helix area (0.1514 m 2 );
u = Undrained shear strength of the soil at helix (80 kPa);
= Unit Weight of the soil (20 kN/m 3 );
h = Depth to helical bearing plate (4.5 m);
= Diameter of the helical plate (0.457 m); and,
c , q y Bearing capacity factors for local shear conditions 2 (N c =31, N q =21,
N y =10).
Generally, across the site using an average undrained shear strength of 80 kPa, Q h =
669 kN. The total capacity of the helical pile equals the bearing capacity of the soil
applied to the individual helical plate(s) plus the skin friction of the shaft. Therefore,
the total bearing capacity of the screw anchor with a shaft diameter exceeding 100
mm is:
Q f is calculated as:
h f
f s
Where:
= Diameter of the pile shaft (0.457 m);
= Height from helix plate to top of soil in skin friction area (0.6 m and 1.9 m); and,
F s = Skin friction of soil in h area (50 kPa and 54 kPa).
Generally, across the site using an average undrained shear strength of 80 kPa, Q f =
53 kN for a 4.5 m long screw pile.
Using the above formula, the following outlines the bearing capacities:
A single helix pile will have an ultimate load capacity of 722 kN;
A double helix pile will have an allowable load capacity of 1171 kN;
2 Das, Braja M., Principles of Foundation Engineering 6 th Edition, pg. 133. Values
taken from Table 3.3.

File No.: FN321
Page 4
For double helix piles the minimal spacing between the helixes is three
times the diameter of the largest helix (in this case 1.4 m);
The minimal spacing between single helix screw piles is three times the
diameter of the helix (in this case 1.4 m); and,
The design for screw anchor piles having different dimensions than the one
mentioned above can be provided on request.
The factored geotechnical screw pile resistance is given as follows:
ɸR n
where:
ɸ is the geotechnical resistance factors as follows:
ɸ = 0.4 for axial compression piles; and,
ɸ = 0.3 for axial tension (uplift) piles.
Screw anchors may be installed in frozen soil. Screw anchors are a favourable
foundation system for structures with lighter loads. These anchors are provided on a
design-build basis. We recommend the anchor designs be prepared or reviewed by a
qualified geotechnical engineer.
3.2 CAST-IN-PLACE CONCRETE PILES
Augered, cast-in-place concrete piles are an ideal system to support the proposed
structure at this site.
Our specific design criteria and recommendations for these foundation systems are as
follows:
1. Pile foundation loads may be supported on piles designed as straight shaft or end
bearing cast-in-place concrete piles.
2. Ultimate values for the design of skin friction and end bearing cast-in-place
concrete piles are presented in Table 3.1:

3.2.

Where:
R n = ΣR n 0.0 m to 2.0 m + ΣR n 2.0 m to 2.6 m + ΣR n > 2.6 m
and
A p is the area of the pile tip (m 2 ); and,
A s is the area of the pile shaft (m 2 ).
The skin friction contribution of the upper 2.0 m of pile below finished grade
should be ignored in the determination of pile capacity.
3. Construct all piles, even lightly loaded piles, with tip depths three times the
depth of seasonal frost penetration to provide sufficient pull out resistance to
potential frost jacking. The frost penetration for exterior concrete piles is
estimated at 2.5 m; therefore, the minimum pile tip depth will be 7.5 m.
4. Typically, belled piles are used to support heavier loads than straight-shaft piles.
In order to derive the design bearing capacity, the base of any belled pile must
be at least five bell diameters below finished surface, or at least 4.0 m below
ground surface in the clay till, whichever depth is greater. End bearing, belled,
cast-in-place concrete piles formed in the clay till may be designed for an
ultimate end bearing of 720 kPa. There is no skin friction contribution in
calculating the capacity of belled piles.
5. The bell base must be at least 200 mm high and the roof of the bell must be no
steeper than 60 degrees, measured from horizontal.
6. Seepage was encountered during borehole drilling so seepage or sloughing will
occur during pile excavations. Casing will be required if seepage or sloughing is

File No.: FN321
Page 7
encountered. Cobbles and boulders are commonly found in till, were visible at
surface, and may cause problems during excavation.
7. During construction, steel reinforcement and concrete must be placed
immediately following pile drilling (and belling if undertaken). Water or slough
must be immediately pumped or otherwise removed prior to placement of
concrete. As such, the immediate placement of concrete following drilling and
belling can improve construction progress and quality of pile construction.
8. Pile shafts must be adequately reinforced to withstand the imposed stresses.
9. Place a void-forming material with a thickness of at least 150 mm beneath grade
beams, foundation concrete or other structural elements supported by piles (all
pile types) to prevent uplifting by soil heaving.
10. The building design must allow no load transfer from stable building elements
supported by the pile and grade beam foundation to potentially vertically
moving building elements supported by the soil or grade supported floors.
3.3 BASEMENT FOOTINGS
Basement footings founded at depths below 2.5 m will likely not be subject to
movements by frost. Footings founded above this depth are subject to movement by
frost, and therefore, will require insulation and heating to prevent frost penetration
below the footing. The recommended insulation configuration for footings above
2.5 m can be provided if required. Temporary structures or structures tolerant to
some movement may be placed on footings at depths within 2.5 m of finished grades.
The following recommendations are made for shallow footings:
1. The footings must be founded on undisturbed native soil. No footings should
be constructed on fill or topsoil.
2. Excavate and remove all topsoil and fill to expose undisturbed native soil as
the founding stratum for footings.
3. Prepare the founding surface by removing any pockets of soft or organic soil
to a uniform bearing surface. The founding surface must be maintained in an
undisturbed state. The surface should not be left exposed to the environment
which could result in wetting, softening or drying.

File No.: FN321
Page 8
4. In areas beneath footings, excavate to expose the founding stratum below the
footing level. Backfill over-excavated areas below the footing with concrete.
5. The footings must be adequately reinforced to distribute the applied loads
and also have sufficient stiffness to distribute local overstresses.
6. Design footings for an allowable bearing pressure of 160 kPa for the silty
sand and clay till. The minimum width for a footing as required by the
applicable building code must be used in design regardless of bearing
capacity considerations.
7. A qualified geotechnical engineer should inspect all footing bearing surfaces
prior to casting footings.
8. Granular backfill for non-basement footings is not recommended because
frost penetration is greater in granular soils than in clayey soils. In cases
where the footing supports a basement wall however, granular backfill is
preferred because it provides better subsurface drainage on the exterior of the
basement wall (lowers the hydrostatic pressure) and tends to settle less than
uncompacted clayey soil backfill. Where granular backfill of basement walls
is used, insulation boards may be required above the footings to prevent frost
penetration below the footing.
9. Settlement of the footings will be less than 25 mm total or differential for the
allowable bearing pressures recommended herein.
Basement and retaining walls must be designed to support the horizontal loads
imposed by the earth behind the wall. If the backfill behind the walls cannot be fully
drained, the hydrostatic forces from impounded water must be added to the wall
loads. Any surcharge loading at the top of these walls, such as parked vehicles, must
be included in the wall loading. The structural design of these walls must provide
mechanisms to prevent leakage, such as water stops and planned shrinkage joints to
minimize random cracking. The exterior of the walls require heavy water proofing
materials.
Place a minimum 600 mm of impermeable clay soil at surface to reduce surface
infiltration into the granular backfill. Provide factory installed geotextile wrapped
plastic perforated subdrain pipes around the base of the basement or retaining wall.
Provide for gravity discharge of the subdrain pipe to a frost-free sump, which is
drained by gravity or level activated pumping.

The soil properties to use in the design of the basement and retaining walls are
provided in Appendix A.
4.0 FLOOR RECOMMENDATIONS
4.1 GRADE SUPPORTED FLOORS
Our recommendations for a grade supported floor slab are as follows:
1. Excavate the existing subgrade soils below the proposed floor slab to
undisturbed, native silty sand. Construction on fill material of unknown quality
and composition can result in uneven settlement or heave. Remove all topsoil
from the floor area during subgrade preparation. Remove all loose soil and
debris. Soft, wet areas, which do not have sufficient trafficability for
construction purposes, should be further excavated and replaced with the pit run
sand or gravel that complies to the specifications in Table 4.1.
2. Scarify and uniformly compacted the upper 200 mm of the subgrade to a
minimum 95% of its maximum dry density as determined by test ASTM D698.
Adjust the water content of the subgrade to within 2.0% wet of the optimum
water content.
3. Any fill material required to raise the grade before construction of the grade
supported floor should be a non-frost active granular soil. Place the structural
fill in lifts not exceeding 150 mm uncompacted thickness and compact to a
minimum 95% of its SPDD as determined by test ASTM D698. Adjust the
water content of the subgrade clay to within 2.0% of the optimum water content.
4. Place 25 mm crushed granular base course, which complies with the
specifications as shown on Table 4.1 and 150 mm thick, on the compacted
subgrade or sub-base. The granular base should be compacted to a minimum
98% of its SPDD as determined by test ASTM D698 using a vibratory
compactor. Water may be used as a compaction aid.
5. Install a layer of polyethylene sheeting 150 m (minimum) thick between the
granular base and the concrete slab to prevent the migration of moisture through
the floor.

File No.: FN321
Page 10
6. Care must be taken during the installation of water and sewer lines to ensure that
any leaks will drain to a sump and will not collect under the floor slab.
7. The building design must allow no load transfer from stable building elements
supported by the foundation to potentially vertically moving building elements
supported by the soil or grade supported floors.
8. Provide positive site drainage away from the building. Minimum slopes of at
least 2% are recommended. Down spouts must have extensions to direct their
flow to discharge points at least 2.0 m away from the building face and
discharge to an area with clearly defined drainage away from the building.
9. Provide separation boards between the floor slab and any footing-supported
structures. This separation prevents load transfer from the moving floor to the
stable, footing supported structure.
10. ABSOLUTELY DO NOT place reinforcing steel to connect the grade supported
floor slab to the edge of the footing. Such reinforcement has two consequences.
First, there will be a major crack and fault in the floor along a line parallel to the
grade beam face at exactly the end of the connecting steel. Second, a strongly
reinforced connection can rotate the top of the footing outward as the floor
adjacent heaves. Structural damage, such as the displacement and pop out of
plate glass windows, has been observed.
11. Use sleeves through the grade-supported floor slab and telescoping or collapsing
connections for all pipes passing through or supported by the grade-supported
floor.
12. Review the building design to identify and revise any construction details which
allow load transfer from moving grade-supported building elements to stable
structurally supported building elements.

Infrastructure, Section 202, Table 202-C.
4.2 STRUCTURALLY SUPPORTED FLOORS
Where heaving or settlement will have unacceptable impacts on floor serviceability,
local areas of structurally supported floors should be provided. For example,
structural floors are often placed below the door swing areas of external doors.
Alternatively, ensure that the top of floor slabs below the exterior door swing is at
least 150 mm below the underside of the door. Floor slabs can heave to block the
swing of doors that are structurally supported by perimeter grade beams.
Our recommendations for structurally supported floors are as follows:
1. The floor should be designed to derive its support structurally from the pile and
grade beam foundation system.
2. The void or crawl space must be a minimum 150 mm below the underside of the
floor slab.
3. If a crawl space is used, provision must be made for accumulated waters to drain
to a frost-free sump by sloping the crawl space floor. Additionally, the soil
below the crawl space should be covered with 150 m polyethylene sheeting
held in place by at least 50 mm of sand. Alternately, a thin concrete mud floor
may be used on the bottom of the crawl space. Ventilation must be provided to

File No.: FN321
Page 12
the crawl space during the non-freezing season to remove moisture
accumulations. It is desirable to design the ventilation system with vents that
may be closed with insulated covers during freezing weather.
Void form systems that rely on the decomposition of an organic void forming
material should be avoided.
5.0 SULPHATE ATTACK
No testing was conducted for water-soluble sulphate contents. As the sulphate
content is unknown, Harder Associates would recommend that the concrete be
designed for severe sulphate levels (Class S-2) with sulphate resistant Portland
Cement (Type 50) having a minimum specified 28-day compressive strength of 32
MPa and a maximum water-cement ratio of 0.45 (see Table 3 in CAN/CSA A23.1-
2009). Calcium chloride or any other admixture containing chlorides should not be
used since the sulphate resisting property of the cement would be reduced. Calcium
salts used as an accelerating admixture should also be avoided as they may increase
the severity of sulphate attack.
If Portland Cement (Type 50) is unavailable or cannot be used due to adverse
construction considerations, then Type 10 cement in combination with 30% by mass
of cement (a little less that 30% by mass of cementing materials) of a Type F or CI
fly ash, is expected to produce sulphate resistance equivalent or superior to concrete
made with a Type 50.
Such concretes have demonstrated good performance in CSA A23.1-09 Table 3 S-1,
S-2 and S-3 sulphate exposure environments. The technical basis for this practice
had its origins in work done by HBT, AGRA Limited and AGRA Earth &
Environmental Ltd in the late 1980’s for the major cement companies in British
Columbia. Referenced publications are:
Sulphate Resistance of Different Types of Portland Cements with and without
Supplementary Cementing Materials by D. Hatch and D.R Morgan
Supplying Concrete for Sulphate Conditions by Mark Stewart

File No.: FN321
Page 13
To enhance durability, an appropriate amount of air entrainment as per CSA
Specification CAN/CSA A23.1-2009, Clause 4.3.3 and Table 4, is also recommended
for all concrete exposed to freezing and thawing at this site.
There may be other design criteria or exposure conditions as outlined in Tables 11
and 14 of CSA A23.1-2009 that could necessitate additional requirements for
subsurface concrete.
If concrete construction proceeds during the winter, Harder Associates recommends
that the concrete be manufactured and placed in a manner that complies with the cold
weather provisions of CSA Concrete Specifications CAN/CSA-A23.1. This
includes:
using a minimum concrete temperature of 10 degrees Celsius;
heating formwork and reinforcing steel to at least 10 degrees Celsius prior to
placing concrete;
heating and hoarding the concrete as soon as practicable after the concrete is
placed and maintaining the temperature of concrete made to CSA exposure
class S-2 at 10 degrees Celsius for a period of at least 7 days or for the time
necessary to attain 70% of the specified design strength; and,
removing the protection at an appropriate rate at the end of the curing period
to avoid cracking the concrete due to sudden temperature change.
6.0 EARTHQUAKE DESIGN PARAMETERS
The soils at the site are generally clay fill overlying clay till. Pertinent seismic data 4
for the proposed office building is provided in Table 6.1 through 6.4, inclusive.
The undrained shear strength is: 50 kPa > S u > 100 kPa;
Site Classification for Seismic Response is Site Class “D” with a
corresponding Average Shear Wave Velocity of 180 m/s < Vs < 360 m/s;

INTRODUCTION
This report presents the results of the geotechnical investigation undertaken for the
proposed light standards upgrade at the Fort Nelson Airport near Fort Nelson, Rc. The new
standards will be replacing existing lighting situated on the airside of the main terminal building,
between the building and apron. A total of 3 light standards will be replaced. It is understood
that few details with respect to the method, size, and condition 0 f the existing 1ight standard
foundation supports are known. At this time, it is understood that new foundations will be
constructed for the new lighting. The easiest and least intrusive method of foundation would
appear to be a pile foundation system.
FIELD INVESTI GATI0 N
. The field investigation for this project consisted of drilling and sampling 3 deep testholes
within each existing light standard. Testhole 04-1 was located at the center standard. Testholes
04-2 and 04-3 were located at the north end standard and south end standard respectively. The
testholes were drilled to depths of 9.5m (Testhole 04-1), and to 6.Om(Testholes 04-2 and 04-3).

J.R. Paine &Associates Ltd. 2
The deep testholes were placed to establish a continuous soil profile complete with strength
parameter testing for foundation design requirements.
The field investigation was undertaken utilizing a truck-mounted soils testing drill unit.
All boreholes were advanced with l50mm diameter solid stem augers in 1.5m depth increments.
A continuous log of the soils encountered was maintained on site during the drilling operation of
each testhole. Noted were soil types, transitions, color, plasticity, relative moisture, consistency,
inclusions, and any other notable physical feature. The auger cuttings were sampled at 0.75m
depth intervals for laboratory analysis. Standard penetration tests were performed at regular
intervals of 1.5m in TH04-l. Upon completion of the drilling program all testholes were
backfilled with drill cuttings.
LABORATORY TESTING
All samples removed from the augers were submitted to the J.R. Paine and AssoCiates
I
Ltd. Grande Prairie laboratory for routine indice testing. All samples were tested for m6isture
content. From these, selected sand samples were processed for grain size distribution. ..J single
sample of clay was tested for liquid limit and plastic'limit determination.
SUBSURFACE SOIL CONDITIONS
For a detailed description of the soils encountered and testing performed specific to each
testhole location, refer to the testhole logs attached. Sod and topsoil, l50mm in thickness, was
encountered at Testholes 04-1 and 04-3. Testhole 04-2 was placed in a paved area revealing
60mm of ACP structure. No gravel was encountered beneath the ACP.
The native inorganic soils encountered at this site initiated with a sand deposit. The sand
exhibited 15% to 32% silt based upon the results of 2 sieve analysis (attached). The sand was of
fine to medium grain size.
A standard penetration test (SPT) 'N' value of 16 blows per 300mm
denoted a sand of medium density. The sand stratum was, primarily, in a damp state although a
zone of saturation was encountered at the bottom of the deposit (where situated directly above
the base clay soils). The sand terminated at depths of2.0m to 2.6m below the ground surface.
The base deposit encountered to full termination depth of all testholes was a glacial
deposit of clay till. The till was characteristically a dense silty clay base deposit exhibiting a
sandy texture and containing occasional pebble to gravel size stones. Liquid limit and plastic

J.R. Paine &Associates Ltd. 3
limit test results of 30% and 14% respectively denote a clay of low to medium plasticity.
Moisture content values were in the mid to upper teen range. Standard penetration test results of
12 blows per 300mm penetration to 16 blows per 300mm penetration denote a clay of stiff
consistency.
Some minor free water seepage was encountered during the advancement of TH04-1 and
TH04-2. The water was dribbling into these testholes at the sand-clay interface, 2.5m to 2.6m
below the ground surface. No significant accumulation of water was encountered at the end of
drilling. No testhole sloughing was encountered.
RECOMMENDATIONS
The soil conditions encountered at this site are considered to be suitable for bored, castin-place
concrete piles.
The lighting standards will subject the piles to both lateral loads and
vertical loads. The following design parameters may be applied to the pile sizing and reinforcing
requirements:

the concrete placement.
All holes should be carefully inspected to ensure that no water or slough
material is present in the hole during concrete placement. Casing for piles and should be readily
available on site to accommodate sloughing conditions or an excess of ingressing ground water.
It is recommended that all piles be adequately reinforced. Concrete for all piles should be
adequately compacted. The pile concrete should be placed as soon as possible after the pile has
been bored.
Screw piles may be considered as an alternative to conventional bored, cast-in-place
concrete piles. It will be difficult to install screw piles through the frozen ground surface. An
allowable soil end bearing value of 200 kilopascals (Clay Till) may be applied to the size
selection calculations of individual screw piles. This value includes the total of all live and dead
loads. If multiple helixes are utilized for individual screw piles, vertical spacing of the helixes
should be at least 5 helix diameters. The bearing depth of the screw piles should be at least 4.6m
below the ground surface. Where multiple helixes are utilized, the upper most helix must be
situated at least I.8m below the ground surface. Lateral spacing between screw piles should be
no less than 4 helix diameters. Pile groupings have not been considered. It is recommended that
torque values measured during the installation process not be used as an estimate of the
geotechnical capacity of the pile. Individual screw piles are not recommended for supporting
laterally loaded structures.
