3. III. Describing Design Phases and Procedures
9. Discuss what is meant by a design process. In engineering, what are the stages in the development of designs?
Answers
A design process is the development of a design. A typical design starts with a design brief, which states the design objectives. Initial ideas are then put together as rough sketches. These are then developed into preliminary drawings, which are more detailed and are often drawn to scale. The preliminary drawings are then developed, incorporating comments from different members of the design team, consultants and the client. Once the design has been sufficiently developed, working drawings are produced. These are then used for manufacturing/assembly/construction. Frequently, working drawings are revised (changed) during this latter phase, in order to resolve technical problems encountered during manufacturing/assembly/construction.

4. III. Describing Design Phases and Procedures
The following extracts from s relate to a project to build an indoor ski complex in Australia, using artificial snow. The messages were circulated by an engineer to members of the design team, and to a specialist contractor. Read the s and answer the following questions. Note that the s are not in the correct order. 1 What are all the s about? 2 What different types of document are mentioned?

9. IV. Resolving Design Problems
Language note You will find the following vocabulary useful in this section. advise, clarify, confirm, disregard, indicate, propose, request, state, work to alternative, as per, clash, conflict, contradict, discrepancy

10. Often conflicting (different) information is shown on different drawings.
On one drawing, the dimensions of a component may not correspond with those shown on a related drawing.
Clashes are another common problem – different drawings may show different components in the same position within an assembly, meaning the assembly will not fit together as designed. Key dimensions and assembly details may also be missing from the set of drawings, leaving the production with inadequate information.
