Hi,
In this post I will explain how to set up, and assign material resources in MS PROJECT 2010.
First I will add three material resources in Resource Sheet:
Now I will add two Tasks:
O.K. Now, I will assign Paint to the Painting the wall task, and Gasoline, and Concrete to the Pouring the concrete Task:
I put 1000 in the Unit field, because I assume that I will need 1000 liters of paint for painting the wall. MS PROJECT 2010 has calculated that the cost is $50.000 (1.000 units X $50 per Unit = $50.000). Remember that this cost remains the same, no matter how long will take you to pain the wall. I will show it to you. First I will choose the Cost table:
and I will get:
Now I will change duration for task Painting the wall from 3 to 10 days:
I will choose the Cost table again, and I will get:
The Total Cost remains the same.
O.K. Now, I will assign Gasoline and Concrete to the Task Pouring the concrete:
I need 5.000 units (tons, liters or whatever) of Concrete and I need 20 liters (or gallons) of Gasoline per hour. MS PROJECT 2010 has calculated that the cost for the Concrete is $500.000 (5.000 units X $100 per Unit = $500.000). For the Gasoline I put in the Unit field 20/h and that means that I will spend 20 liters (or gallons) per hour. MS PROJECT 2010 has calculated that the cost for the Gasoline is $4.000 (20 liters per hour X $5 per Unit X 5 days X 8 hour per day = 20 X $5 X 5 X 8 = $4.000).
What will happen if I change duration of the task Pouring the concrete from 5 to 10 days? Let’s see.
I will choose the Cost table again and I will get:
The Total cost is now $508.000. Why? MS PROJECT 2010 has calculated that the cost for the Concrete is $500.000 (5.000 units X $100 / Unit = $500.000), and it does not depend of the Task duration, since I put in the Unit field 5.000. For the Gasoline I put in the Unit field 20/h and that means that I will spend 20 liters (or gallons) per hour. MS PROJECT 2010 has calculated that the cost for the Gasoline is now $8.000 (20 lites per hour X $5 per Unit X 10 days X 8 hour per day = 20 X $5 X 10 X 8 = $8.000), and the Total cost for this task is $508.000.
So, if you have a Material resource which doesn’t depends of the Task duration you should put the number in the Unit field when you are assigning Material Resource to the Task.
If have a Material resource which does depends of the Task duration you should put the number in the Unit field and how much do you spend per time (hour, day, week, etc.). This is time depending Material resource.
Bye!

Good day
How can I insert a delivery date lets say to the paint so that the painting can not start till the paint arrives
Hi!
Let’s say that you have a Task – Get the paint! then you have a Paint Task. Then make a finish to start relationship, and you are shure that the Paint task will not starterd before you get your paint.
If you know when the pint will arrive, than you do not need the Get the Paint Task! You just set a start date for a Paint Task as Semy flexibile, Start no earlier before, and put the arriving date in the field!
Hope that will help! If not let me know
