Introduction
The IfcConstructionMgmtDomain schema defines concepts in the
construction management (CM) domain. Together with the IfcProcessExtension and
IfcSharedMgmtElementschema it provides a set of models that can be used to
exchange information between construction management applications.
Scope
The IfcConstructionMgmtDomain schema forms part of the Domain Layer of
the IFC Model. It extends the ideas concerning management outlined in the
IfcSharedMgmtElements schema. The objective of the IfcConstructionMgmtDomain
schema is to capture information that supports specific business processes and
resource requirements that are wholly within the domain of interest of the
Construction Manager. The aim is to provide support for information exchange
and sharing within computer aided management applications. The extent of the
model will not support the some of the more detailed ideas found in these
applications.
The following are within the scope of this part of the
specifications:
- Resources used in the construction process including product, labor,
construction equipment, crew, sub-contract and cnstruction material
resources.
- The package of documents used in construction management.
- Specification of construction areas that may be either part of a
product, a whole product or an aggregation (complex) of products (through the
use of the ability to assemble elements within the IfcProductExtension schema).
- Identification of products that result from processes performed that
are used as resources in future processes.
Process Usage
Resources
Resources are considered to be those things that are used within a
process to achieve or assist the process of construction. Various types of
resource are defined within the model.
Documents
For construction management, a single package of documents may be
defined in which all of the documents that relate to the construction prcess
and its management are declared.
Product Composition Structure
Construction management activities may take place either on a complete
product (the whole), on a part of the product or on a set of products acting as
a single product entity (complex). The product composition structure enabling
parts, whole, and complexes to be identified is achieved using the
IfcRelAssemblesElement relationship class in the IfcProductExtension schema.
This points to elements that are subtypes of IfcProduct and that have a
composition structure enumeration which enables identification of the level of
composition concerned.
Products as Resources
A product that results from a process may be used as a resource in a
subsequent process. This is enabled through the IfcProductResource class.
