Let's look at how we can progress our conceptual design.
00:10
The first thing that may be useful is to share our conceptual design, so that other team members can utilize the work that we have done.
00:19
We can use the published Civil Structures function to produce data that can be shared to Civil 3D, and also Revit,
00:26
as we will see in later videos.
00:31
This enables the road designers to make use of the conceptual design and progress their work in parallel to the bridge team.
00:39
Once in Civil 3D, the designer will configure the exchange settings to ensure consistency with existing standards,
00:46
then browse to the shared data that will then be introduced to the Civil 3D drawing.
00:53
This new data includes the surfaces, corridor, road assemblies, as well as the bridge components and the road alignment.
01:08
The bridge design can be progressed beyond that created at the conceptual stage
01:12
by applying modifications to the main components of the bridge.
01:15
Having selected the bridge and made the deck visible, we can change the deck properties by altering the values in the panel.
01:23
In this case, both for deck depth and also for continuity, which will also affect the bridge girders.
01:32
The bridge girders can also be modified for both number and type and for dimensional changes.
01:39
In this case, we are exploring the possibility of changing the girders from a precast concrete arrangement to a dual steel box girder solution.
01:49
Once the girders have been correctly configured for a single span, that arrangement can then be applied instantly to the rest of the bridge.
01:59
Once the girder system has been changed, the designer could then look at modifications to the bridge pier arrangement.
02:08
As with all bridge components, the piers can be modified as before by entering values in the panel.
02:14
We can see here that the designer is making some significant changes to the pier
02:19
by firstly changing the type and number of columns and then increasing both the diameter of the columns and the depth of the pier cap.
02:28
Once those changes have been completed,
02:31
the designer can instantly replicate that pier arrangement to the other piers within the bridge.
02:36
As the girder arrangement has been changed to the steel box girder type with longer span capability,
02:43
it is feasible for the designer to reduce the number of piers to better reflect this.
02:51
The bridge designer may also need to adjust the bridge abutments.
02:54
The designer follows the same process as with other bridge components
02:58
by selecting the component and picking a new part from the available list.
03:03
The default abutment is modelled, and the designer can then make the necessary changes,
03:08
such as in this case with par number and length.
03:14
Lastly, the designer will make changes to the foundations all as before
03:18
until a suitable arrangement has been found and copied to the other foundation positions within the bridge model.
03:25
Using this process, the bridge designer can rapidly develop a conceptual bridge design
03:30
containing the general direction of the project with the initial thoughts and constraints
03:35
to a more crystallized state that can be developed further as the project progresses.
