[00:00:12.870]
<v ->Hi and welcome to our session today,</v>

[00:00:14.310]
where we’re going to look at the new Workflows enabled by

[00:00:17.160]
Leapfrog works and the OpenGround connection.

[00:00:20.320]
My name is Roger Chandler and I’m the director of

[00:00:22.250]
Geotechnical Information Management here at Bentley.

[00:00:24.950]
and I’m joined today by Guillermo from Jacobs.

[00:00:27.860]
Who’s been part of the Bentley and Seequent early adopter

[00:00:30.510]
program for this functionality.

[00:00:32.510]
Welcome to this session and thank you for joining me

[00:00:34.440]
to share these workflows with others.

[00:00:38.700]
<v ->Hi everyone. Thank you, Roger.</v>

[00:00:40.210]
Thank you Bentley and Seequent for inviting me

[00:00:41.493]
to today’s live stream it’s a great opportunity.

[00:00:44.430]
I’m really glad.

[00:00:47.645]
<v ->Well, we’ve had the pleasure</v>

[00:00:48.930]
of working on this presentation now

[00:00:50.560]
for a couple of weeks and we’ve

[00:00:52.140]
prerecorded the workflow so you can get

[00:00:54.160]
as much content as possible into the next 20 minutes.

[00:00:58.090]
Well, obviously you know your way around the

[00:01:01.184]
capabilities of Leapfrog Works.

[00:01:02.550]
So how long have you been using it,

[00:01:04.077]
and what sort of jobs are you currently using it on?

[00:01:08.456]
<v ->Yeah so Jacobs has been been using Leapfrog</v>

[00:01:11.180]
for a few years in Australia and now in the UK.

[00:01:14.615]
We are now really engaged with the Leapfrog and

[00:01:17.925]
the development of this technology,

[00:01:20.250]
which is making a great change in the industry.

[00:01:24.610]
And we are making the best of,

[00:01:26.480]
of the technology development Leapfrog to,

[00:01:31.300]
to develop our, our projects that we are

[00:01:33.650]
now using it in broadly many projects.

[00:01:37.560]
So we are really, really happy to have

[00:01:40.300]
this possibility of a being part of this technology.

[00:01:45.595]
<v ->Excellent.</v>

[00:01:46.428]
It’s always a pleasure to be working with Jacobs

[00:01:48.870]
on our early adopter programs.

[00:01:50.060]
You were early adopters for OpenGround when it

[00:01:52.360]
came out about three and a half years ago.

[00:01:54.660]
So always at the front of the pack.

[00:01:57.437]
Out of a number of users that I’ve been

[00:01:59.460]
working with are using connector purely

[00:02:01.650]
to import geology information from boreholes.

[00:02:05.350]
But I think the workflow’s you’re going to share today,

[00:02:07.240]
go far deeper than that.

[00:02:08.949]
Would you like to just quickly outline

[00:02:11.450]
the three workflows you’re going to talk about?

[00:02:14.707]
<v ->Yeah. So we’re going to present three, three workflows.</v>

[00:02:18.117]
I said, and the first workflow

[00:02:20.557]
is just briefly making the use of the

[00:02:23.030]
connection and how we can integrate

[00:02:25.610]
all the run investigation data stored

[00:02:28.830]
within our OpenGround database in a single model.

[00:02:32.220]
So whenever we need to import different data sources

[00:02:36.860]
or connect to different projects,

[00:02:38.660]
which is a very nice tool and very,

[00:02:40.797]
very clever way of integrating

[00:02:43.470]
different data sets into a single model.

[00:02:46.270]
The second workflow is going to be about

[00:02:48.820]
how to use Leapfrog to clean and reassess

[00:02:53.720]
the information we have in our OpenGround database

[00:02:56.940]
and making sure we can reinterpret the

[00:02:59.820]
correct geologies in this case or making use of

[00:03:02.357]
Leapfrog to really assess the ground condition in a glance.

[00:03:07.485]
And also I work around to reimport back all the

[00:03:11.805]
interpretation and how we have

[00:03:14.010]
cleaned our database data set.

[00:03:16.950]
We reimport it back into our open round database

[00:03:19.560]
And then the final one is going to

[00:03:21.790]
be about making use of the data

[00:03:25.110]
We have imported from open ground and,

[00:03:28.296]
and use it to, to really add the granularity

[00:03:30.620]
to our ground models or reinterpret

[00:03:32.870]
our ground models that are required in more detail.

[00:03:36.360]
Those are going to be the three workflows today,

[00:03:38.190]
so I guess you guys tune in and, and enjoy it.

[00:03:44.330]
<v ->Excellent.</v>

[00:03:45.163]
Now they are brilliant workflows

[00:03:46.550]
and the next 15 minutes are an introduction

[00:03:49.070]
to the true skill and expertise of the

[00:03:50.810]
Jacobs team. So let’s dive in.

[00:03:59.430]
<v ->So what I need to do for this exercise</v>

[00:04:02.630]
is then connect to our OpenGround database,

[00:04:07.640]
ask you to select the cloud you are connecting to.

[00:04:11.000]
Once the project list has been loaded,

[00:04:14.866]
select the one you want to load, and then you click next.

[00:04:20.660]
The following tables will guide you through

[00:04:23.020]
the information you want to load.

[00:04:24.710]
So whatever information you need to import

[00:04:28.000]
to build your model or have an assessment

[00:04:31.300]
on the ground investigation data,

[00:04:34.670]
whether it’s your geology going descriptions,

[00:04:39.987]
your coring information,

[00:04:42.960]
any Institute tests, you might have.

[00:04:45.380]
[It’s]very important aspect to select this the way

[00:04:49.380]
you want to import that data, either

[00:04:52.060]
as an interval, or as a point.

[00:04:56.550]
So once you select the ones you want to load,

[00:04:59.150]
you will have another loading window

[00:05:02.180]
in which the detailed information

[00:05:05.540]
you want to bring to your scene is going to pop up.

[00:05:09.430]
You will filter whatever information

[00:05:12.400]
you don’t need, or it might be

[00:05:14.747]
formatting in a way Leapfrog works.

[00:05:19.300]
So your bar holds up in loaded and you can quickly

[00:05:22.760]
select the information you want to bring,

[00:05:25.000]
click next and you go through the next of the stages.

[00:05:27.830]
For people who are more familiar

[00:05:30.080]
with leapfrog this is common sense.

[00:05:35.990]
Your geology, you can load whatever information

[00:05:39.660]
you have in your database with coring information,

[00:05:45.902]
it’s similar to select what’s your interval range.

[00:05:49.740]
What is your depth,

[00:05:51.947]
what is the top of your core recovery,

[00:05:57.821]
what is your total core recover, your solid core

[00:06:00.880]
recover, your quality designation.

[00:06:05.800]
That’s going to bring the coring information

[00:06:10.465]
for the standard penetration test.

[00:06:13.580]
We can import your numeric data or your N60,

[00:06:21.280]
or your lab testing, [You] can select

[00:06:25.080]
the right information from your testing.

[00:06:28.900]
Again, I go for the particle size distribution tests

[00:06:35.950]
and so on with the book that’s being loaded.

[00:06:44.860]
So once your boreholes have been loaded,

[00:06:47.470]
the investigation data has been loaded.

[00:06:52.381]
You can always import it in to your scene

[00:06:54.380]
to see it in three dimensions.

[00:06:57.190]
So that was a very good improvement.

[00:07:01.130]
So another workflow I would like to show you how

[00:07:04.500]
to connect to different projects from OpenGround

[00:07:09.070]
That’s always useful when your data

[00:07:11.660]
is not collected in a single project.

[00:07:14.490]
If you want to bring that information, into your scene,

[00:07:19.263]
rather than combining into your master project,

[00:07:23.145]
you can always bring that project into your model,

[00:07:28.670]
connecting to another project in OpenGround,

[00:07:32.470]
and bring another boreholes set or GI set to your model.

[00:07:40.780]
So again, the same pop-up window in which

[00:07:43.350]
we can assign information we’re going to bring.

[00:07:47.170]
And then the data we want to import mostly,

[00:07:52.900]
which is this CPT data, can import

[00:07:56.220]
the current resistance and the side friction.

[00:07:59.825]
We can be looking at that. I’m not going to import

[00:08:02.717]
the geology then I’m not interested.

[00:08:04.650]
I just want to look at the CPT result

[00:08:07.910]
the 3D scene in a very quick way.

[00:08:12.760]
My CPT is loaded. We can always relabel

[00:08:16.790]
the data set so that way, we have

[00:08:21.316]
loaded two projects into the scene.

[00:08:24.590]
And as we have two data sets loading to Leapfrog,

[00:08:29.780]
we can use that information to perfectly see

[00:08:34.065]
the information we might be interested in showing,

[00:08:37.554]
for example, bringing graphics to the scene.

[00:08:41.500]
So we’re looking into RQDs or the core resistance.

[00:08:47.070]
We can look at the graphics very quickly

[00:08:51.000]
and the same with a CPTs.

[00:09:00.690]
So, another very interesting feature,

[00:09:02.853]
having the ability to connect to OpenGround

[00:09:06.264]
it is the the way we can reload the information

[00:09:11.120]
and refresh the information as,

[00:09:13.810]
database progresses, or if another change

[00:09:17.836]
in the database has happened either by

[00:09:24.200]
collecting new data or amending information.

[00:09:28.313]
So this was a very nice example doing that,

[00:09:35.000]
we are going to change just one coordinate

[00:09:38.910]
in one of our, one of our project boreholes

[00:09:42.400]
so we can move it.

[00:09:44.046]
Assuming as an example, this position was relocated,

[00:09:48.566]
but we have received the correct coordinates

[00:09:52.620]
in which then the whole model will

[00:09:57.100]
reprocess this information and

[00:09:59.854]
the project is up to date against the database,

[00:10:05.780]
which is where you want to store your,

[00:10:09.920]
your information very much up to date and

[00:10:13.890]
keep that information in OpenGround,

[00:10:16.540]
rather than working only in Leapfrog.

[00:10:21.150]
Maybe we load the entire project or

[00:10:24.030]
the entire information we have loaded.

[00:10:26.370]
And once you click on reload data,

[00:10:29.585]
that information will reload and

[00:10:35.180]
the whole model will reprocess against

[00:10:38.429]
the up-to-date database.

[00:10:47.800]
Okay, so one good technique

[00:10:49.780]
we can develop to make use of the,

[00:10:53.540]
of the tool is to load your information

[00:10:57.480]
in 3D, as we have already done,

[00:10:59.966]
but then, have a look at if we

[00:11:03.010]
are happy with the description,

[00:11:06.166]
and the information we have received.

[00:11:09.823]
I’m going to just demonstrate how to

[00:11:12.660]
load your geological information.

[00:11:16.500]
And we can always compare this information against

[00:11:20.185]
what we would expect as in term of geologies.

[00:11:23.670]
We can see here, we have a, an alluvial valley,

[00:11:26.620]
on the east side of the scene in which

[00:11:29.943]
we would expect alluvium and river terrace deposits

[00:11:33.670]
on the side of the, of the project.

[00:11:37.300]
However, we have received lots

[00:11:39.200]
of information from our contractor,

[00:11:42.220]
nothing, all these different alluvial deposits

[00:11:47.470]
likely on the wrong, having labeled them incorrectly.

[00:11:55.010]
For that reason for our purpose,

[00:11:56.410]
we can generate a new column that will make our

[00:12:00.890]
interpretation for that we’re going to

[00:12:03.814]
select the east interval selection

[00:12:07.010]
once we select the new column tool,

[00:12:10.930]
which will bring the column we want to correct.

[00:12:17.272]
I’m here, we’re going to to try to reclassify this,

[00:12:22.630]
all these alluvials, alluvium deposits,

[00:12:26.540]
a description to the right geological unit.

[00:12:31.390]
So we won’t believe all these alluvium,

[00:12:33.950]
on this hilly area belong or are really alluvium.

[00:12:39.650]
So we’re going to bring and amend

[00:12:42.750]
this description to the right geology.

[00:12:48.580]
So now we have legally correct information

[00:12:54.360]
from the alluvium deposits and the same we can use

[00:12:58.010]
for this had deposits in which we are not sure

[00:13:01.557]
but we can be sure that this information is incorrect.

[00:13:05.870]
We going to make a correction on this.

[00:13:09.960]
We have now created a new column in,

[00:13:13.440]
our dataset that would have geology code interpretation.

[00:13:21.660]
Having created this interpretation column.

[00:13:25.050]
We can then report this as, as it is

[00:13:31.370]
interpreted into our database, but

[00:13:34.690]
for that we are going to export these descriptions

[00:13:39.930]
to generate a new file that we can then

[00:13:49.305]
reimport back into OpenGround.

[00:14:00.105]
OpenGround will need to read the

[00:14:03.830]
information in the same way as it specs.

[00:14:08.200]
We are going to, import what we have amended

[00:14:15.330]
in our Leapfrog projects so we can update

[00:14:20.070]
our database with the correct information

[00:14:23.950]
and the right geology as we have proven.

[00:14:35.580]
Once we have generated a basic model,

[00:14:38.996]
we might want to add some more

[00:14:41.292]
granularity or more detail to our model.

[00:14:44.590]
That case we have modeled a very simple model

[00:14:48.100]
of superficial and bedrock units.

[00:14:51.350]
So for that we have merged some of the geology

[00:14:54.734]
descriptions and combining them

[00:14:58.510]
into superficiales and bedrock.

[00:15:00.920]
However, we need to interpret the

[00:15:03.770]
weathering profile or whats the,

[00:15:06.860]
the competent bedrock expected depth

[00:15:09.860]
and for the design of a particular asset.

[00:15:13.600]
So, we are looking into a cutting here.

[00:15:16.940]
So we want to just do the interpretation

[00:15:19.761]
of our borehole information and

[00:15:22.840]
use that from the information

[00:15:24.910]
we have loaded from OpenGround.

[00:15:27.920]
So we, bring the coring information

[00:15:31.120]
as we have done earlier.

[00:15:34.520]
We can clearly start to see a pattern in

[00:15:38.663]
our geology or our other recovery in our bedrock unit.

[00:15:45.250]
And in this case is this green, volume.

[00:15:49.574]
So if we wanted to use the information

[00:15:53.470]
as contained in OpenGround and

[00:15:56.730]
regarding the coring information,

[00:15:58.433]
we can reinterpret this coring recovery

[00:16:01.873]
and the RQD information to provide

[00:16:06.860]
a differentiation between the different,

[00:16:11.364]
bedrocks of units we might want to classify.

[00:16:15.190]
So for that, we can generate a new column

[00:16:19.370]
on the coring information data,

[00:16:23.200]
that will bring us a chance to reclassify

[00:16:27.630]
that not only as a unit, as a unique unit,

[00:16:33.113]
but as to differentiate the different subunits.

[00:16:37.990]
For that we’re going to use the same interval

[00:16:41.270]
selection option we were using for the cleanup

[00:16:44.420]
of the, of the data shown earlier.

[00:16:47.460]
And then we can reclassify the geology code based

[00:16:53.770]
on our interpretation of the coring information.

[00:16:57.760]
And again, interpret that geology as, we would like.

[00:17:07.507]
So, once we have all our data,

[00:17:13.232]
so that we can then change what we

[00:17:16.010]
want to use to reclassify that.

[00:17:18.560]
And for that, we the RQDs we were showing earlier,

[00:17:23.840]
and we’re going to use this tool to pick up

[00:17:28.310]
the different subunits in the rock unit.

[00:17:34.342]
We’re going to be selecting different coverings.

[00:17:40.010]
This going to be pretty crude for you but,

[00:17:43.466]
you can go as detailed as you want.

[00:17:51.210]
Okay.

[00:17:52.270]
So now that our boreholes in our remodel area,

[00:17:57.240]
have been reclassified, we can reassign this

[00:18:01.180]
to the geology or the subunit we want to create.

[00:18:05.183]
So we can now create a new lithology,

[00:18:08.170]
that will classify the covering details

[00:18:12.300]
we have selected as a new subunit.

[00:18:15.840]
Now that we have one subunit, we can save this,

[00:18:28.830]
we can have a clear boundary between

[00:18:32.710]
those two subunits, as you can see

[00:18:34.640]
between these pinks and the browns.

[00:18:41.328]
So from here, we can then remodel

[00:18:45.380]
the surface underneath the different layers.

[00:18:51.470]
So generate a new layer that will split this bedrock unit

[00:18:56.360]
into two subunits, and the ground modeling,

[00:19:03.868]
it will generate a new surface.

[00:19:08.729]
I have already done that and

[00:19:12.020]
we can show how this has been created.

[00:19:18.590]
So we can split our ground model

[00:19:20.810]
into two different subunits for the bedrock.

[00:19:23.840]
So we can be sure our rock unit is divided into

[00:19:28.420]
the different, subunits you want to classify.

[00:19:35.641]
<v ->Thank you very much for those great workflows.</v>

[00:19:37.840]
I have one final question for you before we finish today,

[00:19:39.870]
what is your favorite feature of

[00:19:41.753]
OpenGround Connector and Leapfrog works?

[00:19:45.970]
<v ->I think this connection brings the best of both worlds.</v>

[00:19:48.990]
We have been using open ground for many, many years,

[00:19:53.880]
and, and it’s the best way to keep our, our data,

[00:19:57.940]
our Geo data, and how we can manage our

[00:20:01.280]
ground investigation data in a very solid way.

[00:20:04.540]
And, and we want to keep doing it.

[00:20:07.110]
So it’s, it’s always a very good thing about it to,

[00:20:12.200]
to, really make a connection that is going to,

[00:20:14.905]
make all the changes, [to] update our ground model.

[00:20:19.330]
So whenever something, a new ground investigation,

[00:20:22.580]
new phase of ground investigation [has arrived]
[00:20:25.250]
we need to make a change in our database.

[00:20:27.930]
All those changes can then be reflected

[00:20:30.010]
into our Leapfrog model.

[00:20:31.710]
Whether it’s just for visibility,

[00:20:33.815]
or just if we have developed detailed ground models,

[00:20:38.335]
all those, changes will apply into our ground models

[00:20:42.100]
and then our, our ground models

[00:20:44.170]
can count with the latest information,

[00:20:47.650]
to store in our OpenGround data database.

[00:20:49.606]
So I think it’s, [an] exciting time now

[00:20:52.850]
that both are connected and, we’re going to be part

[00:20:56.647]
of the same company and the same workflow

[00:20:59.810]
with a seamless, seamless experience.

[00:21:05.080]
<v ->Very good.</v>

[00:21:06.630]
Well, I hope everybody has taken something

[00:21:09.130]
from the presentation today,

[00:21:10.320]
and have come away with at least one idea

[00:21:12.700]
on how to use your ground investigation data

[00:21:14.830]
from OpenGround to refine your Leapfrog model.

[00:21:17.647]
Thank you ever so much for your time today

[00:21:19.840]
and the time in the preparation of this presentation,

[00:21:22.830]
it’s been a true pleasure working with you

[00:21:24.570]
over the last few weeks.

[00:21:27.240]
<v ->Thank you, Roger.</v>

[00:21:28.327]
Thank you all for tuning in bye-bye.
