Description

This course focuses on practical field skills, data collection, analysis and the presentation of results from field work. It also introduces generating maps and engineering geological models using traditional and computing-based methods.

Engineering geology is a field-based subject using observation, interpretation and synthesis to develop appropriate models of 4-D site geology to provide key linkages with civil, mining and/or environmental practice. This course assumes ability to undertake basic field mapping, and focuses on advanced mapping and logging techniques at various scales. Geomorphic mapping techniques are an integral part of engineering geology practice, and the ability to “read” the landscape is a fundamental skill that enables sound communication with other geotechnical practitioners. Logging skills are developed in this course, and the use of aerial photograph interpretation is emphasised as a key skill. ENGE411 further develops logging skills.

Learning Outcomes

  • Understand and apply geological and geomorphological principles to mapping and data collection for engineering purposes.
  • Demonstrate skills in field data collection for engineering purposes, including recording observations in a notebook, mapping, face and core logging.
  • Prepare for and conduct specific site investigations, and show advanced understanding of investigation requirements.
  • Demonstrate an ability to critically analyse data requirements and geological limitations to quantitative understanding of site conditions.
  • Formulate geological ground models based on site investigation data, and understand different types of engineering construction requirements.
  • Achieve all of these outcomes within the cultural and regulatory environment of the project location.

Prerequisites

(1) GEOL351 and (2) Geol 352 and (3) approval from the Head of Department of Geological Sciences

Timetable Note

Week One (19th-23rd February)

The first week of the programme is designed to introduce students to the fundamentals of Engineering Geology methods and practice, and to assess the background knowledge of the 2018 cohort. The over-riding assumption is that all students are enrolled in ENGE410 and ENGE415 concurrently: for the student only doing one of the two papers exceptions will be made in terms of assessment requirements. The Week One programme is as follows:

Monday 19th February:
9:00-10.30am  -  Introduction to 2018 programme (MCV, CHF, DHB)
11.00-12.00pm  -  Meeting & briefing with HoD and Technicians
12.15-1.45pm  -  Group Lunch (Tandoori Palace, Ilam Road)
2.00-4.30pm  -  Guest lectures by two recent graduates

Tuesday 20th February:
8.30-12.00pm  -  Ground models and their importance (CHF)
1.30-5.00pm  -  Geo-logic and the art of geotechnical practice (DHB)

Wednesday 21st February:
8.30am-5.30pm  -  Field trip to Port Hills & Akaroa (CHF, DHB)

Thursday 22nd February:
8.30-12.00pm  -  Field notebooks & site investigation overview (CHF)
1.30-5.00pm  -  Canterbury earthquakes & site investigations (DHB)

Friday 23rd February:
8.30-12.00pm  -  Mathematics, statistics & mechanics overview (MCV)
1.30-4.30pm  -  Building structures on Christchurch ‘soft ground’ (DHB)

General Note: Students are expected to take comprehensive notes in class, and record relevant field data in their notebooks for submission and review at end of Week One. Worth 5% for each course.


Week Two (26th February to 2nd March)

The second week of the programme is based at the Cass Field Station in inland Canterbury, and involve a mix of field mapping and site visits. The group is to meet at 8.30am on Monday 26th February for a full briefing, including health and safety issues. Students are expected to have PPE available (hi-vis, safety glasses, safety boots), and to take personal requirements including sleeping bag, pillow, towel and hygiene/medical requirements. Trip leaders are CHF and DHB, and following itinerary is scheduled subject to change depending on weather or other issues:

Notebooks are to be submitted for marking as required.

Weeks Three to Five consist of sessions relating to both courses (ENGE410 and ENGE415), together with a weekly field trip, as set out below but with the proviso of changes due to weather or other constraints. The full day (8.30am to 5.30pm) is allocated to the particular topic, and may include office, laboratory or field work. ENGE410 material will be taught by DHB and ENGE411 material by CHF, unless otherwise advised:

Notes

Background:

For 2018 the teaching of ENGE 410 and ENGE 415 has been combined because of the close interrelationship between site investigation and an understanding of landscape evolution. Instead of block teaching, the courses have been extended to cover Term One of the academic year and allow more time for review of fundamentals. Two long field trips are included where field investigation techniques and geomorphological skills are developed. Each course is separately assessed and graded: details of the assessment schedule are given at the end.

Students are advised that personal protective equipment (PPE) is required for field work and site visits. This includes safety footwear, hi-vis jacket, safety glasses, hard hat and gloves. Some of these items may be borrowed from the Department in the short-term, but as professionals students are expected to obtain requisite equipment promptly. Other field equipment (eg geological compasses) will be provided.

Indicative Fees

Domestic fee $1,046.00

* All fees are inclusive of NZ GST or any equivalent overseas tax, and do not include any programme level discount or additional course-related expenses.

Minimum enrolments

This course will not be offered if fewer than 10 people apply to enrol.
