Site investigation is the first crucial step in design and construction when

the cost and practicalities of building project on a particular site are

evaluated. It is vital to the success of any construction project, since

inadequate investigation can lead to very large construction over - runs. In

order to be effective, site investigation must be carried out in a systematic

way using techniques that are relevant, reliable and most effective.

The overall responsibility for the consequence of site investigation is

increasingly placed on Engineers, even when the work is carried out by

others; the need for them to understand and be fully in control of the

process has become imperative. This is to ensure our structures are Build

on Sound Foundation.

We offer clients a full range of Geotechnical engineering and geological

services, including site exploration and evaluation of geologic hazards,

development of foundation, earth work recommendations and

construction monitoring. We can also integrate Geotechnical engineering,

engineering geology, seismology and environmental services to facilitate

sitting and design of dam structures as highlighted below:

To ensure adequate foundation for the dam axis and the embankment, it is

necessary to conduct extensive investigation on the proposed dam axis

and the availability of the local soil material within the vicinity of the dam

site.

Therefore, the under mentioned tests are quite relevant for site exploration

and evaluation:

* Geophysical Investigations.

* Conduct Dutch Cone Penetration Test (DCPT).

* Conduct Standard Penetration Test (SPT) at every 1.5m depth

interval in order to determine in - situ, the shear strength of the soils

at which the core of the dam will be founded.

* Coring of rock samples to analyze the rock samples and ascertain

any geologic hazards.

(A). Drilling Methodology (Test Boring)

The borehole will be done in continuous coring mode with drilling guage

Ø 130mm – 85mm in diameter, decreasing towards the bottom. With

simple and double core barrel to make sure the maximum core will be

recovered.

To hold the wall bore, we will use a casing (temporary tube) Ø 150-

101mm in diameter decreasing towards the bottom.

The core sample will be stored in soil sample box, for each samples we

will have the following records: borehole number, withdraw depth, data,

station, starting and ending tripping points.

(B). STANDARD PENETRATION TEST (SPT)

Standard penetration test (SPT) will be carried out at 1.5m intervals in

slightly to fairly consistent or loose soils. SPT will be conducted in

SITE EXPLORATION, CHARACTERIZATION AND EVALUATION

Page 18: COMPANY PROFILE - Sitech Engineeringsitech-engineering.com.ng/.../01/Sitech-Engineering-Corporate-Profile.pdf · 1.12 In-situ dry density; core cutter method. 1.13 Speedy moisture

accordance with ASTM D1586-92. The SPT will be done using a split -

barrel sampler having 2" outside diameter. During the SPT test, the

sampler will be hammered into the ground with the number of blows

recorded. The sample would be collected in a dedicated split spoon

sampler that will be opened on site.

The standard penetration tests (SPT) involves driving a split-spoon

sample barrel into the ground from the bottom of a borehole by dropping

a 140 lb (63.5kg) hammer a height of 30inches (0.76m); from the test, a

penetration resistance or blow count (N-value) is obtained which equals

the number of blows to drive the sampler over the depth interval between

6 and 18 inches (150 to 450mm). The N-value is reported in blows per

foot (blows per 300mm). Standard testing procedures are described in

ASTM D 1586.

Main specifications are as follows:

Testing points will be done at 1.5m interval drilling, calculating the Nvalue

reported in blows to drive the sampler at the depth of equal interval

15cm each one of the split-barrel sampler;

For each test, first will be done the cleaning of the end-boring, removing

any obvious contamination derived from drilling. Sign the water level;

The samples will be removed from the split-barrel and wrap it or seal in a

plastic bag to retain moisture. Mark the sample “bottom” if applicable

and label it with an identification number, withdrawal depth and

withdrawal station;

The test will be stopped when the sum of the number of blows for

increments

“N”value it will be N = 50 blows;

Where the test will achieve Nvalue = 50 the boring test shall be continued

until an appropriate bearing stratum where more than an Nvalue = 50 is

found and further drilling shall be conducted into the stratum at least of

5meters in depth; Find the plates 4.1-4.3 showing the various drilling

Rigs.

If the test will not be meeting the above conditions (Nvalue = 50 blows or

boring reaches rock stratum) within 50 meters in depth, the bore drilling

will be stopped.

(C) CONE PENETRATION TEST (CPT)

Page 19: COMPANY PROFILE - Sitech Engineeringsitech-engineering.com.ng/.../01/Sitech-Engineering-Corporate-Profile.pdf · 1.12 In-situ dry density; core cutter method. 1.13 Speedy moisture

The cone penetrometer test consists of forcing a hardened steel cone

continuously into the ground and measuring its resistance to penetration.

The standard cone used has an apex angle of 60o and a base area of

10cm2.

The hydraulic operated static penetrometer of 20Tons was used in the

cone resistance soundings. The machine consists of a steel frame carrying

a driving head which houses the hydraulic capsule. The driving head can

raise or lowered by manually operated winch or motor driven hydraulic

ram.

Mechanical mantle cone with friction jacket was used in the operation.

The cone assembly is pushed into the ground by means of steel rods,

connected length, into the driving head. Discontinuous sounding

procedure was adopted in the test. The cone in its retracted position is first

force into the ground at a distance of 20cm by application of force to the

outer sounding tubes. The cone is then pushed out at a distance of 4cm at

rate approximately 1cm/secs. The pressure required to advance the cone

transmitted through the capsule in the driving head to the gauge is

recorded. The machine measures skin friction value of the material with

friction jacket behind the cone. The outer tube is then advanced a 20cm

further where the same operation is carried out and recorded. This

procedure is repeated until a refusal where the total resistance to

penetration of the tube and cone reaches that of the machine.

Successive cone resistance readings are plotted against the depth to form

resistance profile. The tests are conducted according to ASTM D5778

standards.

( D ). LABORATORY TEST

The undisturbed samples should be withdrawn in the cohesive soil (sandy

silty, silty sand, clayey sand, clay, etc....).

On the disturbed sample for the incoherent soil (or soil with little contents

of clay or silt) should be done geotechnical tests as well as follows:

One-Dimensional consolidation (oedometric test) with calculation of

following parameters: mv, Cv, K

Triaxial test Unconsolidated Undrained.

The TEAM field engineer will inspect and describe the samples collected

in accordance with ASTM D2487-92 “Standard Classification of Soils for

Engineering Purposes (Unified Soil Classification System)”. Each sample

will be placed in a plastic bag for further identification tests in the

laboratory.

In zones of extremely consolidated soils or very soft rocks (sandstones,

marls, and clays), rotary coring will be undertaken using at least 76mm

nominal diameter double tube, with face discharge rotary core barrels. In

case of low recovery with the diameters, larger ones will be used.

For each core, the Total Core Recovery (TCR) will be recorded along

with the Solid Core Recovery (SCR) and the Rock Quality Designation

(RQD). For each run, the coring time will be recorded and the water

return status will be noted as these parameters provide very useful

information on the hardness of the rock encountered and the extent of

fracturing. The TEAM Supervising Engineer will record the spacing of

the fractures within the rock and classify the rock, as well as note the

groundwater depth if it is encountered. The structural details will be

recorded in accordance with the general methods proposed in ‘The

logging of rock cores for engineering purposes’, Report of the Geologic

Society Engineering Group Working Party, Quarterly Journal of

Engineering Geology, Volume 3, No. 1, December 1970.

Rock samples will be placed in designated boxes and photographed. The

selected samples designated for laboratory testing will be properly double

wrapped in order to avoid any loss of moisture.

The disturbed samples will be labeled as follows;

Station;

Top sample and bottom sample;

Withdraw data;

the following field investigation shall be carried out.

9.1 Shallow –Foundation analysis and formulating of geotechnical design

provision are generally approach in the following steps:

Establish project objectives and design or evaluation conditions;

Characterize site Stratigraphy and soil rock properties;

Page 28: COMPANY PROFILE - Sitech Engineeringsitech-engineering.com.ng/.../01/Sitech-Engineering-Corporate-Profile.pdf · 1.12 In-situ dry density; core cutter method. 1.13 Speedy moisture

Evaluate load bearing fill support or subsoil improvement techniques;

Conduct performance, constructability and economic feasibility systems.

9.2. Deep Foundations

Deep foundations, such as piles, drilled shafts and caissons, should be

considered when;

* Shallow foundations are inadequate and structural loads need to be

transmitted to deeper, more competent soil or rock;

* Structures are required to be supported over water

* Functionality of the structure does not allow from differential

settlement.

9.3 Grouting for Ground Engineering

* Grouting in ground engineering is the process of controlled

injection of material, usually in a temporary fluid phase, into soil or

rock, where it stiffens to improve the physical characteristics of the

ground for geotechnical reasons.

Grouting uses in geotechnical engineering range from in filling voids to

compensating for volume loss in tunnelling .The variety of available

techniques (permeation, hydro-fracture, jetting and mixing) and grouts

(cements, clays, chemicals, resins, polymers etc) provide the means to

solve many ground engineering problems.

Parker/Lugeon Test are carried out to assess the permeability of borehole

as it intersects with various hydrogeological units.

9.4 Ground Improvement

Ground improvement may increase strength, increase or decrease

permeability, reduce compressibility, improve stability or decrease wave

due or frost or swelling

10.0 PILE FOUNDATIONS

Piles are convenient method of foundation construction for works over

water, such as jetties or bridge piers or where uplift loads must be

resisted.

The company has the capacity to undertake the construction of;

Driven and cast-in-place piles – Formed by driving a tube with a

closed end into the soil, and filling the tube with concrete.

Page 29: COMPANY PROFILE - Sitech Engineeringsitech-engineering.com.ng/.../01/Sitech-Engineering-Corporate-Profile.pdf · 1.12 In-situ dry density; core cutter method. 1.13 Speedy moisture

Bored and cast-in-place piles-Piles formed by boring a hole into the

soil and filling it with concrete

Micro piles – These are Bored piles of shallow depth

Allowable Pile Capacity

A load which is not less than the specified working load and which

takes into account the factor of safety, settlement, overall bearing

capacity of the ground beneath the piles. This is the ability of the pile

to meet the specified loading requirements.
