The real planning process can now start, and the first task is to get a survey of the main installations, including the buildings with necessary rooms and heavy fixed installations. This is done through a room programme (Table 22.2). Here a first estima-tion of the need for size and area is also given.
A given production will, for instance, need a tank volume based on the requirements of the fish. If the production of fish is known, some assumptions about the space for feed storage can be made. Some rooms, such as a changing room, bathroom, mess room and office may also be necessary. The aim of the room programme is to obtain some idea about the size of the different rooms and installations which can be used in the further analyses, not to make a complete list of what the facility is going to look like when it is finished. By summing all these components an estimate of the total size of the plant is obtained.
