Additional fields available in Asta Powerproject 4D

Asta Powerproject 4D includes the following IFC-related fields in addition to the fields that are available in standard Asta Powerproject. They appear in an "IFC" category, whenever you see a categorised list of available fields. You can display these fields in the spreadsheet and in text annotations, filter and sort/group on the contents of the fields and use them when constructing formulae.

For each field listed below, the following information is given:

  • Description - the information displayed by the field when added to the spreadsheet or to a text annotation.
  • Parameters - any additional, optional parameters that you can use to modify the information that the field displays or the way in which the information is displayed.
  • Editable? - whether the field is editable when displayed in a spreadsheet column. If a field is editable in the spreadsheet, you can change the data displayed in the column to edit the properties of the corresponding task.

IFC product

Description

The name of the IFC product search or IFC product selection with which a task is associated.

 

Ways of associating 3D objects in a 3D model with tasks

Parameters
  • Data - whether you want to display information relating to the live data or to a specific baseline.
  • Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
Editable? Yes

IFC product area

Description The area of all 3D objects that are included in the IFC product search or IFC product selection with which a task is associated. This information is calculated by Asta Powerproject 4D, rather than being derived from the 3D model, which results in a more accurate value in some cases.
Parameters
  • Data - whether you want to display information relating to the live data or to a specific baseline.
  • Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
Editable? No

IFC product build order

Description

The build order - a numerical order that can be assigned to 3D objects in a 3D model that have been created as a result of splitting one 3D object into multiple objects - of the 3D objects that are included in the IFC product search or IFC product selection with which a task is associated. If you assign a build order to split 3D objects, it is used to determine the order in which split 3D objects appear during timeline simulations in cases where more than one object is assigned to a single task. You can also use the build order as a criterion when creating IFC product searches, to specify which 3D objects should be included in an IFC product search. You can view the build order of 3D objects in the IFC Properties pane; note that the build order of non-split 3D objects defaults to 0.

 

Specifying the build order of split 3D objects

Parameters
  • Data - whether you want to display information relating to the live data or to a specific baseline.
  • Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
Editable? No

IFC product count

Description

The number of 3D objects in a 3D model that are associated with a task, either by an IFC product search or an IFC product selection.

 

Ways of associating 3D objects in a 3D model with tasks

Parameters
  • Data - whether you want to display information relating to the live data or to a specific baseline.
  • Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
Editable? No

IFC product entity

Description The IFC entity of 3D objects in a 3D model that are associated with a task. The IFC entity indicates the type of 3D object. For example, a 3D object that represents a railing may have an IFC entity of "IfcRailing"; an object that represents a door may have an iFC entity of "IfcDoor". You may find this field useful if you write formulae relating to the 3D objects in a 3D model. For example, if you were to write a formula to calculate the volume and pour size of concrete slabs, you could refer to this field in the formula to limit the formula to 3D objects with an IFC entity of "IfcSlab".
Parameters
  • Data - whether you want to display information relating to the live data or to a specific baseline.
  • Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
Editable? No

IFC product volume

Description The volume of all 3D objects that are included in the IFC product search or IFC product selection with which a task is associated. This information is calculated by Asta Powerproject 4D, rather than being derived from the 3D model, which results in a more accurate value in some cases.
Parameters
  • Data - whether you want to display information relating to the live data or to a specific baseline.
  • Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
Editable? No

IFC simulation profile

Description

The IFC simulation profile that is assigned to a task. You can use IFC simulation profiles to control the way in which 3D objects in a 3D model are "built" during timeline simulations. If an IFC simulation profile is assigned to a task, it defines the build behaviour, transparency, build colour and on time, early and late/critical highlight colours of all of the 3D objects in a 3D model that are associated with the task. Using IFC simulation profiles to control the way in which 3D objects are built gives you much more flexibility than using IFC task type.

 

Configuring the way in which timeline simulations run

Parameters
  • Data - whether you want to display information relating to the live data or to a specific baseline.
  • Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
Editable? Yes

IFC task type

Description

The type of activity, in BIM terms, that a task represents, for example Construction, Installation or Demolition. You can use IFC task type to control the way in which 3D objects in a 3D model are "built" during timeline simulations. Using IFC task type to control the way in which 3D objects are built gives you much less flexibility than using IFC simulation profiles.

 

The following IFC task types are available:

  • Attendance. Apply this to tasks that represent the presence of a resource, or a period of waiting for one or more events to occur.
  • Construction. Apply this to tasks that represent erecting, fabricating or building something.
  • Demolition. Apply this to tasks that represent pulling down, destroying or breaking down something.
  • Dismantle. Apply this to tasks that represent taking apart something carefully, so that it can be recycled or reused.
  • Disposal. Apply this to tasks that represent getting rid of something.
  • Installation. Apply this to tasks that represent installing something; this is similar to the 'Construction' task type, but is more commonly used for engineering tasks.
  • Logistic. Apply this to tasks that represent transporting or delivering something.
  • Maintenance. Apply this to tasks that represent maintaining or servicing something to keep it in good condition, or in good working order.
  • Move. Apply this to tasks that represent moving something from one place to another.
  • Operation. Apply this to tasks that represent the working or running of something.
  • Removal. Apply this to tasks that represent taking something away from its place of use.
  • Renovation. Apply this to tasks that represent restoring something to an 'as new' state.

Configuring the way in which timeline simulations run

Parameters
  • Data - whether you want to display information relating to the live data or to a specific baseline.
  • Specific task - specify specific task(s) on a multi-task bar to which you want the field to refer if required.
Editable? Yes
