Learning Outcome 3: Analyse soil properties determined by geotechnical procedures.
Learning Outcome 3: Produce a proposal to address identified geotechnical weaknesses and problems
Assignment Brief:
Scenario
As an assistant civil engineer with a large engineering firm, you have been tasked with preparing a report based on survey and soil sampling for a proposed construction project. The proposal is for a large infrastructure project which will include tunnelling and bridges, in an area of mixed geological conditions. The survey, site investigation and soil sampling were undertaken by a different firm; so you are relying on their data.
In preparing your report, you are asked to use industry standard language, include references (as necessary) to ensure that your calculations, comments and recommendations are supported by research and analysis. Your report is intended to be read by the lead civil engineer for your company but will also be available to the client.
Your report is expected to address:
Task 1 - Rock types and impact on civil engineering projects
• rock types found on the site
• weathering of soil and rock on the site
• any issues of discontinuous rock mass found on the site
• the use of rock and un-cemented sediments found on site
In addition, your employer has also requested that you research and prepare a (10-minute) presentation for the rest of the assistant civil engineers in the company on how the discontinuous nature of rock has created problems for tunnelling and bridge building and the solutions which have been used to overcome them. (optional)
Task 2 - Site investigation and soil classification to current codes
• Examine and evaluate the range of ground investigation techniques/sampling available and the range of soil classification tests available in relation to the current codes of practice.
• Summarise the importance of these processes in determining the soil properties and the impact this will have on infrastructure projects.
Scenario
Following your geotechnical report, your employer has tasked you with developing a design proposal for the project; a new road bypass including a bridge/overpass.
Based on the survey data, soil sampling and testing, you are asked to develop drawings and specifications to support your design proposal.
In addition, you will need to prepare a short project report that includes key research, calculations and justification for your proposal.
Your design and project report should seek to address:
• A clear site plan, showing the existing conditions.
• Description of how the following soil properties are determined and analyse of results for site: soil moisture content density specific gravity shear strength compressibility liquid and plasticity indices California bearing ration.
Your design drawings and specifications should show:
• road foundations
• embankments
• bridge foundations.
Your report should demonstrate and justify how the test data have been used to overcome identified geotechnical weaknesses and to inform the final design solution.
