In a project plan beside the Start and Finish date of activity, we also need to know When we need resource, and How many resource we need.
I will show you how to do it.
We have a simple project with 3 activities and is assigned resource as follow:
- Activity A : 10 worker and 1 Crane
- Activity B : 5 worker and 2 Crane
- Activity C : 20 worker
Now we will make a Labor, Equipment mobilization plan so that we know when we need the resource and how many we need.
First we need to make some configuration. Go to menu Admin -> Admin Preferences. Click on Time Periods tab. Edit the Hours value to match with your Project calendar.
For example if you use 6 days work-week, you have to adjust Hours/Week is 48, Hours/Month is 208 (8 x 26), Hours/Year is 2496 (208 x 12)
After finish, click Close button.
Click on Resource Usage Spreadsheet button.
Hold Ctrl button and select 2 resource : Worker and Crane
Now data will show on the right.
But all data is in Units format. We may don’t care number of unit, we only care number of person or equipment.
You will right click on the table and select Spreadsheet Options
Click on Calculate Average and Base on Hours per Time Period
Now you can see the figure show in number of person and equipment.
On the week of 29-Sep you will need total 35 workers and 3 cranes.
You can also print the report by going to Print Preview
With this Resource Mobilization Plan you know when you need resource and how many.
Thanks for this presentation.
I was wondering, should the hours per week be 48 instead of 56?
Also, I noticed you used 26 days per month for a 6 working day week. Is this the standard number of days to use for a 6 day week.
What is the standard for a 5 working day week? Is it 22?
I think he depends on calocations
1 week = 6 working days = 8×6 = 48 hours “8 working hours/ day”
So if your calender based on 5 working days per week
So 1 week =8×5 =40 hours
For month calculations.. we use the standard 4 weekends per month
So if your calendar 6 working days that means 4 off days per month;
Working days per month= total days per months – total off days
Total days per month=30 days
For 5 working days :
Off days = 2×4= 8 d
Working days per month= 30-8 = 22 d
So working hours/month= 8×22 = 176
For year= monthly working hours× count of months
= 176 ×12= 2112 h
I hope that you find it easy
Mayada give a correct answer.
It depend on how your company define working day and non-work day. You can talk with Human resource department for the most exact answer.
How does this work with multiple projects?
Will this work if work activities follow different calendars?
1. I can work fine with multiple project as long as all the projects use the same calendar.
2. No, I think it will not work with multiple calendar project.
Good post. Though my problem is the “Calculate Average Based on Hours per Time Period” does not work. Checking it does not convert units of hours to number. Is there a way to resolve this?
I Trust you are very well
The way you explained the labour and equipment mobilization is very good, in my opinion this examples will work perfectly for plan only. how ever for updating the actual I have faced some problems in that.
here I have mentioned some of my query related to this topic. if possible can you please give some suggestion in that.
how does it will work for actual progress update?
Does the actual cost for each labour and equipment is working fine?
how the actual quantity is being measured and updated for this case either by units, Duration or physical?
Thanks in advance
Basically P6 control by Units, so even you see the number is in person or machine but in fact P6 save in database in Unit format.
You will update in Unit format as usual. For example if this week we actually have 10 worker on site, you will update Actual Unit is 480 ( 10 worker x 8 hours/day x 6 days/week). And in the Mobilization table, if you show Actual value, P6 will show 10.
Regarding actual cost, it still work as usual, it is not affected from showing data like this.
Thanks for the valuable post.
Depending on which criteria exactly that we can choose amongst the different duration types?
I had an article explaining your question here https://doduykhuong.com/2018/03/25/how-to-use-activity-duration-type-in-primavera-p6/
