COURSE MODULE (and code): MEng Inter-Disciplinary Design Module CIVE461
ASSIGNMENT TITLE: Coastal quarry feasibility scheme
Lecturers responsible: S G Millard, R G Tickell, H A Khalid
Date set: Monday, Week 1 (i.e. First week of Semester 1)
Required date of submission: Friday, Week 12
Latest date of submission: Friday, 1 week later
Penalty scheme for late submission: scheme A (see year notes)
_____________________________________________________________________________________
Aims: The feasibility design exercise gives MEng students the opportunity to study a complete civil engineering scheme from concept to demonstration of a workable solution. Emphasis is placed upon teamwork between different disciplines, reaching a cost-effective, practical solution.
Details: See following:
Outline brief
This feasibility study is focused on the design of a coastal quarry on a fictitious site to the west of Colwyn Bay, North Wales. For simplicity the habitation of Rhos-on-Sea has been removed and replaced with agricultural ground. See attached map ( Ordnance Survey, Landranger series 115, "Snowdon & surrounding area").

Limestone will be extracted from the planned quarry and crushed on site. To minimise the environmental impact on haulage through the neighbouring habitation, it is planned that the majority of aggregate will be transported by sea. The principal market for this aggregate is seen as the construction and roads industries in London. There will be an asphalt coating plant operating on the quarry site. Delivery of the hot asphalt and haulage of the coated limestone aggregate will be by road.
Existing roads providing access from one side of the site to the other must be maintained.

For design purposes assume that all drift may be up to 3.5m deep
MEng students will be grouped into two competing teams who will prepare feasibility reports for the leasing of the land and operation of the quarry.
You are required to consider the following issues in your documents:
|
rail |
road |
You will be required to consider the structural aspects of:
Note that all aggregate is expected to be supplied to purchaser dust-free and completely free of marine salt contamination. Aggregate is required in a range of sizes from 50mm to fine sand. In addition some large rock sections of up to 5 tonnes may be set aside for coastal defence schemes or amenity usage.
Geological and marine charts of the area are made available to each team. Note that these may also be modified to some extent to facilitate the scheme.
Where you find there is specific information that you require that you do not presently have, this must be requested in detail and in writing from:
Dr S G Millard
North Wales Regional Coordinator, Quarries

All letters sent and received should be appended to the final
report. You may send letters by email (ec96@liv.ac.uk),
but these must still be formal letters in Word format, attached as a document
to the email.
Verbal requests, scribbled notes or raw-text emails will not be accepted.
You must not contact local authorities, central government
or their agencies (EA etc). This is to avoid causing needless alarm amongst
local inhabitants.
Your immediate action must be to elect a Group Leader, who will be responsible for coordinating the design, but will have his/her own design to do as well. You should then begin an outline study of how you plan the quarry to operate and who is going to be responsible for which parts of the design. You must work as a coordinated team. A substantial proportion of the assessment will be on the team performance.
Remember to take notes and photographs of both quarry visits, see details below. There is a lot to see…you will not remember it all!
Timing
Two visits to local quarries are being arranged:
Make sure that you wear rugged/weatherproof clothing and stout footwear, i.e. boots or strong walking shoes. Anyone turning up in training shoes or similar will only see the quarry from the inside of the bus! You will be provided with a construction safety helmet and high-visibility waistcoat. Like all construction sites, quarries are potentially dangerous places.
Please listen to and take heed of all safety instructions given at the start of the visit.
Note that neither of these quarries represent the details of your scheme. Do not simply copy what you see as being the only good/possible solution. Every quarry is different in its layout, design and operation. It is unlikely that these quarries will present the optimum solution to your design.
On Monday afternoon, week 6, each team will present an outline presentation of their scheme. This will take the form of a poster presentation of the scheme and a 30-minute oral presentation.
A final group presentation in the form of a bound (A4) report must be submitted by Friday, week 12, i.e. the last day of Semester 1. Each page of the submission must be on departmental calculation sheets and must contain details of the individual student responsible. All work must be independently checked by another student in the team. At the foot of every page must be the name and signature of the student responsible for the work and the checker.
Assessment
Week 6 poster presentation Group mark 15%
Week 6 oral presentation Group mark 15%
Final Report Group mark 30%
Individual mark 40%
Marks for the Final Report will be awarded for both technical content and quality of presentation. Untidy or unprofessional returns will be heavily penalised.
Quarry details
The following details are representative of a "typical" quarry and may be used to assist you with your design:

A schematic flowsheet of the quarrying process for Llanddulas has been provided to each team as a guide. However there may be more or fewer processes in your quarry.
Schematic flowsheet for Llanddulas quarry (Large! Needs Acrobat~pdf Reader v.4 to view. If you see a blank page when you access this image then you probably have v.3 installed. Go to Start & New & Viewers to install v.4. You should also be using Netscape v.4.75 or later)
