IV Resolving design problems

12 In pairs, discuss problems that can arise when different drawings that make up a design
are not properly coordinated.
13a The following records are from the indoor ski complex project. They show
correspondence between the design team and construction team. Read through the texts
quickly and answer the following questions.
1 What is the general subject of the correspondence?
