Riverbed for Revit Model Sharing.....What does it cost?
There are many scenarios we can use, but for this example, assume that your firm has 4 Architects who are working with a Partner firm on a Revit project. The Revit Model will be stored on the Partner's server.
For testing purposes, we'll utilize testing that CSG performed on our network, accessing the Model on a Partner firm's server. CSG strongly encourages our Proof of Concept program as a means of testing on your own network, as the per hour conclusions are based on the network configuration, including bandwidth at each location.
Connection type: Virtual Private Network (VPN)
Connection speed: (client side) Cable connection, 16.96Mbps down, 1.59Mbps up. (server side) 10Mbps Fiber connection to the internet.
Model size: 75MB
Software: Revit Architecture 2011
Without Riverbed:
Each open of the Revit Model: 2 minutes, 56 seconds
Each Sync to the Central File: 4 minutes, 27 seconds
Assuming two "opens" of the Model per day: 5 minutes, 52 seconds per day waiting on opening the Model (per project team member)
Assuming you Sync to Central File 8 times a day (once per hour): 35 minutes, 36 seconds per day waiting for Syncing to the Central File (per project team member)
This is 41 minutes, 28 seconds in a person's 8 hour day, or roughly 9% of a person's day, spent waiting.
If you bill your Personnel at $75 per hour, this equates to a loss of $54 per day, per user.
There are 250 working days in a year (5 days X 50 weeks), which equates to a loss of $13,500 per year, or $6.50 per hour, per person on the project.
With Riverbed:
Each "Warm" open (model has been opened once): 56 seconds
Each Sync to Central File: 41 seconds
Assuming two "opens" of the Model per day: 1 minute, 52 seconds per day waiting on opening the Model (per project team member)
Assuming you Sync to Central File 8 times in a day (once per hour): 5 minutes, 28 seconds per day waiting for Syncing to the Central File (per project team member)
This is 7 minutes, 20 seconds in a person's 8 hour day, or roughly 1.5% of a person day spent waiting.
If you bill your Personnel at $75 per hour, this equates to a loss of $9 per day, per user.
There are 250 working days in a year (5 days x 50 weeks), which equates to a loss of $2250 per year, or $1.08 per hour, per person on the project.
With the Riverbed Solution in place, we'll return $11,250 per year back to the company, per user. This equates to $5.41 per hour. If we have 4 project team members working on this project, then we are returning a combined $21.64 per hour back to the company, simply by eliminating the wait time in opening and syncing to the Model across the WAN/VPN connection.
Equipment cost:
Assuming 4 people need to be involved in this project, your total cost over a 3 year period (including the Riverbed device, services, and maintenance) is $6395. Over a 3 year period, that equates to $1.02 per hour, or divided by the number of Project team members on this project (4), this equates to 25.5 cents per hour, per user.
Conclusion:
The "cost" of the Riverbed solution in this specific example is $1.02 per hour. The "return" back to the company is $21.64 per hour, resulting in a Net Gain of $20.62 per hour !!!
