Course Structure

• Aims
• To provide an understanding of the scale and
  range of civil and offshore engineering works,
  including the techniques used in marine, coastal,
  estuarine and onshore situations.
• Objectives
• This course is intended to enable you to
  communicate effectively with other professionals
  and members of the public about aspects of
  construction in marine and coastal environments.

Asessments

• Presentation projects (40 total) Each student
  (working in groups) will contribute to 2 projects
  that will be presented by the group to the full
  class. Each presentation (10) will be supported
  by a written summary from each individual student
  (500 words plus 4 illustrations maximum 10).
  The presentations will be peer ranked.
• 2 class tests of 30 each. During each test
  students will write 2 brief reports (from a
  selection of topics), 1 on a tutor presented
  topic and 1 on a student presented topic not
  their own. March 11 April 22

Talking the TalkBrief Outline of Some
Engineering Terms

• Weight Mass
• Kilograms
• Force
• one of Newtons laws
• Newtons

7
Equilibrium

• Consider a book sitting on a table

F
If Upwards is positive, then R-F0 RF

Another of Newtons Laws To every action there
is an equal and opposite reaction.

Consider Book Falling

• Assume parachute very light

Another of Newtons Laws

• A body will remain at rest or continue to move
  with a constant velocity unless acted upon by an
  external force.

Stress Simplistic Approach

Strain One Simplistic Definition
12
The Important Bit

• Stress relates to the force or load applied to a
  body.
• Strain relates to deformation.

Structural Failure

• Strength
• Stiffness
• Stability
• Robustness
• Durability
• Other Serviceability

The Legal Framework

• HSE

• CDM

• SEPA

• Building Regulations

The Important Bit

• Enabling legislation
• The details can change sometimes a lot.
• The client (i.e. the person for whom the
  structure is being built) has duties under the
  law (except for domestic or very small scale
  work).
• Always check on the current situation.
• The HSE is not always your friend.
• You need planning permission unless you are the
  Queen. Your L.A. will usually give you advice.
