Course Learning OutcomesOn successful completion of this course students will be able to:
1 Interpret and summarise desktop information to predict the expected soil and groundwater conditions prior to undertaking a site investigation; 2 Scope and plan site investigations that are feasible, cost effective and appropriately characterise the ground; 3 Develop an idealised geotechnical model that summarises the ground profile and identifies and quantifies key parameters needed for design; 4 Calculate 2D seepage, pore pressure coefficients, time-dependent consolidation, lateral earth pressures, loading induced stresses and displacements, and bearing capacity of shallow foundations; 5 Design retaining walls, foundations, and analyse the stablility of slopes; 6 Evaluate design options and specify final design recommendations based on factors such as sustainability, construction feasibility and cost effectiveness; 7 Measure soil properties in the laboratory and interpret and summarise the data.
The above course learning outcomes are aligned with the Engineers Australia Stage 1 Competency Standard for the Professional Engineer.

The University's policy on Assessment for Coursework Programs is based on the following four principles:
- Assessment must encourage and reinforce learning.
- Assessment must enable robust and fair judgements about student performance.
- Assessment practices must be fair and equitable to students and give them the opportunity to demonstrate what they have learned.
- Assessment must maintain academic standards.

The University places a high priority on approaches to learning and teaching that enhance the student experience. Feedback is sought from students in a variety of ways including on-going engagement with staff, the use of online discussion boards and the use of Student Experience of Learning and Teaching (SELT) surveys as well as GOS surveys and Program reviews.
SELTs are an important source of information to inform individual teaching practice, decisions about teaching duties, and course and program curriculum design. They enable the University to assess how effectively its learning environments and teaching practices facilitate student engagement and learning outcomes. Under the current SELT Policy (http://www.adelaide.edu.au/policies/101/) course SELTs are mandated and must be conducted at the conclusion of each term/semester/trimester for every course offering. Feedback on issues raised through course SELT surveys is made available to enrolled students through various resources (e.g. MyUni). In addition aggregated course SELT data is available.

Students are reminded that in order to maintain the academic integrity of all programs and courses, the university has a zero-tolerance approach to students offering money or significant value goods or services to any staff member who is involved in their teaching or assessment. Students offering lecturers or tutors or professional staff anything more than a small token of appreciation is totally unacceptable, in any circumstances. Staff members are obliged to report all such incidents to their supervisor/manager, who will refer them for action under the university's student’s disciplinary procedures.
The University of Adelaide is committed to regular reviews of the courses and programs it offers to students. The University of Adelaide therefore reserves the right to discontinue or vary programs and courses without notice. Please read the important information contained in the disclaimer.
