Similarly, the other buildings shown on Fig. 3.8, can be grouped into four corners
(or elsewhere) of the land available (Fig. 3.9).
However, both building configurations (Figs. 3.8 and 3.9) can be fed differently
with differing lengths and pipe sizes. This will influence the cost of the infrastructure
services provision.
If there are four adjoining plots similar to Fig. 3.9 which are located around a
street corner (see Fig. 3.10), the pipe routes and sizes can again be different.
On Figs. 3.1 and 3.5, the buildings are surrounded by green space. In contrast, the
layout of Fig. 3.11 shows a courtyard layout, where the green space is surrounded by
buildings, of low to high rise size. Here again, the way the customers are provided
with their services will affect the lengths and sizes of infrastructures services
provided (pipes, cables, etc).
Although single lines are mostly shown on the figures above, Fig. 3.7 shows how
sometimes two lines may be installed on the same road, one on each side, so as to
minimise disturbance to road users and customers during repairs and maintenance
works.
