Course Description

This unit of competency covers the skills and knowledge required to analyse and design residential slabs and footings, shallow footings in general and retaining structures, as well as select piles, underpinning methods and their applications, based on the fundamental principles and concepts applied to deep foundations, underpinning, trenching and sheet piling.


National Codes, Titles, Elements and Performance Criteria

National Element Code & Title:

EAC030B Analyse and design foundations

Element:

1. Select an appropriate footing type.

Performance Criteria:

1.1 Understanding of the broad classification of foundations is used
in the selection of footing types.
1.2 Understanding of the uncertainties and potential legal problems
is used to inform footing decisions.
1.3 The correct investigation and monitoring techniques are named
for a specific project.
1.4 Understanding of Factors of Safety is applied to footing design.
1.5 Appropriate footing types are selected for specific sites and
project and the reason for each selection documented.

Element:

2. Carry out simple footing design to AS 2870 "Residential Slabs and Footings".

Performance Criteria:

2.1 The scope of AS 2870 is understood and used to inform footing
design.
2.2 Variation in foundation behaviour as it relates to the complexity
of footing design is understood and used to inform footing
design.
2.3 Sketches are prepared of slabs and footings for different loads
and soil types based on AS 2870.
2.4 Special considerations for footings on variable foundation is
understood and used to inform footing design.

Element:

3. Carry out simple shallow footing designs based on the principles of soil mechanics.

Performance Criteria:

3.1 Designs are prepared for simple shallow footings based on
formulae for calculating bearing capacity.
3.2 Consideration is given to correct soil parameters, the water table,
proximity of slopes and presence of rock.

Element:

4. Calculate stresses in a soil mass.

Performance Criteria:

4.1 Calculations are carried out to determine the stresses in a soil
mass due to footing pressure, the immediate elastic settlement,
the total final settlement and the tolerance of the structure to
settlement and differential settlement.
4.2 Immediate and final consolidation settlements are estimated.
4.3 Comments are made on the tolerance of the building to the
estimated settlement.

Element:

5. Design simple cantilever and gravity retaining walls.

Performance Criteria:

5.1 Understanding of common types of retaining structures and their
uses is applied to retaining wall design.
5.2 The active/passive wall pressures and forces are determined.
5.3 The active pressure coefficients for saturated and drained clays
are determined.
5.5 The surcharge forces, bearing capacity, settlement and factors of
safety are calculated.
5.6 Calculations are carried out to design simple cantilever and
gravity retaining walls to resist sliding and overturning.
5.7 Sketches are drawn showing the main features including
adequate drainage.

Element:

6. Select pile type/s and prepare a design.

Performance Criteria:

6.1 Appropriate pile types are selected, given a building plan,
structural loading and site data from lab and field test.
6.2 Understanding of the difference between driven and bored piles
is applied to pile design.
6.3 Common pile driving formulae are used to analyse and design
single driven piles.
6.4 The capacity of single piles and pile groups and their probable
settlement is calculated by static analysis.
6.5 Sketches are prepared of some typical pile caps showing pile
type and layout, dimensions, load carrying capacity and pile cap
details.

Element:

7. Determine appropriate underpinning for various situations.

Performance Criteria:

7.1 Appropriate underpinning for various situations is identified.
7.2 Understanding of the number of underpinning methods and their
applications is applied to underpinning.

Element:

8. Design and analyse unsupported excavation trenching.

Performance Criteria:

8.1 Unsupported excavation trenching is designed and analysed.
8.2 The safety of an excavation trench can be assessed.

Element:

9. Design a cantilever sheetpiling wall.

Performance Criteria:

9.1 A cantilever sheetpile wall retaining cohesionless soil is
designed.
9.2 A cantilever sheetpile wall retaining cohesive soil is designed.
9.3 The maximum moment acting on a sheetpile wall is determined
and a suitable profile chosen from design charts.
