Costing Material - Type Resources
Summary
Resources that do not charge by time can be handled easily within
Microsoft Project. Here we show how these can be assigned and their
costs distributed across tasks as required.
Defining
Material - Type Resources
Firstly, define the consumable resource.
- Choose: View - Resource Sheet.
- Enter the name of the resource in the 'Name' column
- Choose 'Material' in the 'Type' column,
- Optionally enter a unit (e.g. liters, meters) in the 'Material Label' column,
- Enter the unit cost rate in the 'Std Rate' column for the
material.
If the type is made to be 'material' standard rate is interpreted
as a unit cost. If the type if 'Work' it is taken to be a time-based
cost rate. This is new in Project 2000 and later versions.
Assigning Materials Resources
The assignment is the same for all resources. Return to the Gantt
chart.
- Select View - Gantt chart.
- Enter tasks and then assign the material resources.
For example, split the screen (Window - Split) and enter the
number of units you require. The cost will be calculated accordingly.
To confirm this, right click the lower half of the screen and select
'Resource Cost'.
Distributing
Material Costs Across Several Tasks
If a material cost is to be distributed across several tasks, Select
a Standard Rate, which divides exactly into the various costs you
require for each task. The values you get when you divide the desired
cost by the cost rate is the number of units you will need to assign
to each the respective tasks.
For example, if material costs of $300 and $500 are needed at two
different tasks for the same material, define the standard rate
to be $100, since this divides exactly into both dollar values (3
and 5 times respectively). Now assign 3 and 5 units of this resource
to two tasks to obtain this dollar amount.
The "Cost Per Use" field
If you need to introduce a 'one off' cost each time a resource is assigned, enter this amount in the 'cost per use' field on the Resource Sheet. Flag fall or 'call out' costs can be represented in this way.
