Building (Generally)

A building must be defined for the order of magnitude cost to be determined.

A building is (if specified) associated to a site. It is therefore a requirement that, before a building can be specified, a site must exist.

Several buildings may be defined to test the order of magnitude of cost for various building options; it is anticipated that each building will be associated to its own elemental site.

A building may span over several connected or disconnected buildings. To allow for this, a 'building complex' can be defined which comprises several elemental buildings.

Similarly, a building can also be broken down into several identifiable parts or sections. To allow for this, a 'building part' can be defined such that an elemental building comprises several building parts.

Note that dimensional and shape representation information about the building need not be given at this stage.
Note that reference elevation above sea level of the building and reference elevation above sea level of the terrain around the building are not required for this Exchange Requirement. Elevations necessary may be determined from site information.

Building information required to establish 'order of magnitude' cost includes:

Information Needed	MAN	REC	OPT
Specification of the site on which the building is contained.
Specification of building name and description if required.
An extended name for the building may also be specified if required
Specification of whether the building concerned is a complex of several buildings, an elemental (single) building or a part of a building.
Where the building is a 'complex', identification of the elemental buildings that are nested into the complex.
Where the building is a 'part', identification of the building into which the part is nested. It should be noted that the 'part' breakdown of a building may give rise to parts that overlap in terms of their shape content. Therefore, the overall shape of a building should not be derived by adding together the shapes of parts.
The postal address for the building, if available, may be given.
