Cost types

A cost type is a standard dimension used to capture and categorize project cost details in construction projects.

Each project typically has different cost types related to labor, materials, rented equipment, and other operational costs. Standard cost types serve as templates for creating new cost types.

Each cost type is associated with a task, which is in turn associated with a project. A cost type record is uniquely identified by the standard cost type used to create it, as well as the specific project and task it applies to.

Note: In the construction industry, the cost type corresponds with the category in the work breakdown structure (WBS).

List cost types.

get/objects/construction/cost-type

Returns up to 100 object references from the collection with a key, ID, and link for each cost type. This operation is mostly for use in testing; use the query service to find objects that meet certain criteria and to specify properties that are returned.

Create a cost type
post/objects/construction/cost-type
Creates a new cost type. When you create a cost type, the following field values from the given standard cost type are used unless you override them:


    

  • accumulationType
    • 

  • glAccount
    • 

  • parent
    • 

  • item
    • 



Custom field values from the standard cost type can also be used by the cost type. For this to work, the standard cost type and the cost type must have same custom fields with the same IDs, types, and lengths. Custom fields of type Sequence are not copied.


Parent-child relationships defined by standard cost types are preserved when cost types are created.
