The Virtual Reality BIM Immersion Experience

Anticipated Research Leader
s
:
Daniel Comeaux

&
James Ross



OBJECTIVE

To utilize
open source collaborative Virtual R
eality software, such as
RealXtend/OS
-
BEST
, and
commercial off
-
the
-
shelf
equipment, such as immersion goggles and 3D LCD displays, to provide a
platform that allows Army Corps of Engineers (ACE) BIM
-
CAD personnel the ability to provide an
immersive and editable BIM Virtual Reality environment. This will allow ACE staff
, consul
tants

and
clients
to collaborative explore

and edit BIM designs

while moving through the environment as "avatars"
which represent various classes of end
-
users for the building under design.

APPROACH

In order to achieve the platform that is outlined above
we propose the following incremental
development milestones:


Select Open Data Format
:
Various projects are underway to develop Open Formats for BIM

models which are not proprietary or vendor specific including IFC,
aecXML
,
CIS/2
. An important

early ste
p for this project is to select a data format to be used for immersive BIM models. Input

from ACE BIM
-
CAD center is critical at this stage to insure that the tool developed can import

models from the most commonly used BIM design software.


Import BIM

Mo
del
s into Collaborative VR
: The
second

major milestone will be to
develop a

bridging program to
import
BIM
model
s

into a virtual environment.

Rather than
importing all

BIM model information into VR, embedded data will be extracted
, converted to an open data

format

and stored in an external open source database with matching keys stored in sub
-
objects

within the
VR
BIM

model
.


Display and Editing of Embedded BIM Information
:
Once BIM models can be

successfully

imported into coll
aborative VR the next step is to allow avatars to view and edit embedded

information in the model. This will be accomplished by (1) "listening" for avatar actions which

indicate desires to view or edit a sub
-
object within the design, (2) retrieving stor
ed keys in sub
-

objects, (3) querying the external database to retrieve related information and, (4) displaying

and allowing editing through popup forms. Early versions will be demonstrated to ACE CAD
-
BIM

staff to facilitate the development of viewing a
nd editing modes that will be useful in the actual

BIM design and evaluation process.


Editing Sub
-
Objects Shape and Dimensions
: The intention of this project is not to duplicate

design features that are well developed in commercial BIM design software,

but the ability to

make minor changes
to
the BIM model
immersed

in VR

could be very valuable. This will be

accomplished by modifying the collaborative virtual reality environments built
-
in object editing



features to add a "callback feature" which will

report all changes in shape and dimension to the

external database.


Export Tool
:

The last step of this pilot project will be to provide an easy path to export the

modified BIM model back to the proprietary design software where various built
-
in

report
ing and publishing steps can be executed.

The resulting tool will be demonstrated in a half day workshop which will take participants on a "round
trip" from a proprietary design tool, into collaborative virtual reality, through a collaborative immersive
ed
iting session and back to the BIM design tool.

DELIVERABLES

The primary deliverable for this project is an Open Source software package (written in C#, C++, and CG)
which (1) uses an open format for BIM, (2) imports BIM models into immersive collaborative
Virtual
Reality, (3) provides tools for collaborative immersive editing of BIM sub
-
objects, (4) provides basic
collaborative immersive editing of BIM sub
-
object dimensions, shapes and textures, and (5) provides
export functions to return collaboratively ed
ited models to commercial BIM design tools. The software
package will have an install script and preset demo.

The secondary deliverables are intermediate quarterly progress reports, a 1/2 day workshop
presentation to introduce the completed tool and a fin
al report (50 pages) documenting all activities.

INNOVATION

The concept of using a virtual environment to help visualize a real world
building development
has been
used in other projects. One
outstanding example was

a hospital

design

where the designers were

able
to go through hallways into a patient’s room and move and touch objects (Dunston

2009
).

Another
example of virtual reality is seen with the construction of nuclear plants in the United States. “Ongoing
research aims to dete
rmine if virtual reality technology can be effectively used to reduce construction
and maintenance costs” (Whisker

2009
).

We believe that the end product of this p
roject will be able to help the
ACE
CAD
-
BIM center
to
collaborate with customers and other
stakeholders to assess and modify BIM model during the design
phase.


The repository of completed immersive BIM models will also form a useful body of knowledge
which can be shown to customers in the early design phase to more easily decide upon the best
possible
template for the customer
'
s need. These benefits will result in reduction in project cost and time for the
ACE CAD
-
BIM center.

PERSONAL EXPERIENCE AND GOALS

We have enjoyed working on several
Collaborative Virtual Reality Projects for professors
Strelzoff and
Sulbaran
.
A gallery of
our
previous VR projects is displayed below:



Chilean
CVRE
Conference

Project for French Professor Virtual Refinery
(not properly operated)


We would love the learning experience of working with
the Army Corps of Engineers CAD
-
BIM center on
virtual reality systems and BIM
.

Our goal for this project is to
produce a tool which becomes widely
used by ACE to help develop BIM models which are used as designs for real world construction projects.



Fostering Construction Management Implementation of BIM at Engineering
Research Development Centers

Anticipated Research Leader:
Cara Percy

OBJECTIVE


The U.S. Army Corps of Engineers (USACE), at the national level, has developed a road map for
implementa
tion of BIM for use in civil works projects on a nationwide level. However, at the level of the
local Engineering Research Development Centers (ERDC) adequate training in BIM for Construction
Management has not been prioritized. The focus of this project i
s to provide specific operation
guidelines to determine the district’s visions and expectations for BIM usage in Construction
Management.

APPROACH

The following are steps to accomplish the goal.

o

Identify current status quo



Software



Equipment



Personnel

Research



Investigation

o

Create and action plan for the implementation of BIM in construction management, according
to the results of the research and investigation of the ERDC’s specific visions and expectations
(Beth A. Brucker, 2006).

o

The development of defined steps necessary

to implement BIM in Construction Management.
As a result the ACE can follow and distribute the action plan in the future to reach their
expectations (Salman Azhar, 2007).

o

Development of BIM adoption workshop curriculum in collaboration with ACE CAD
-
BIM st
aff.

o

Delivery of BIM adoption workshop at Construction Management conferences and ACE districts
chosen in collaboration with ACE CAD
-
BIM staff.

DELIVERABLES

The primary deliverable for this project are course materials (50 pages) for a 1/2 day workshops fo
r BIM
adoption by Construction Managers associated with ERDC which matches the goals and needs for
USACE. This material will be delivered in one or more 1/2 day workshops at sites to be determined by
USACE CAD
-
BIM center.

The secondary deliverables are i
ntermediate quarterly progress reports,
a BIM for ERDC Construction
Managers action plan (30 pages), 1 hour presentation of action plan at USACE CAD
-
BIM center
or other
selected venue
and a final report (50 pages) documenting all activities.

BENEFITS/INNO
VATION

This project will benefit the USACE by applying the ERDC’s vision of BIM in Construction Management
and implementing the necessary actions to obtain those specific goals (Beth A. Brucker, 2006). This
action plan’s results are important to ACE becaus
e without clearly defined visions and expectations how
can they achieve the full implementation capabilities of BIM in Construction Management (Salman
Azhar, 2007).

PERSONAL EXPERIENCE AND GOALS

I have personal experience in 2D design as well as 3D design
and modeling gained throughout my
career at USM and internships over the past four years. In my capstone course, I developed a parametric
model from which I extracted my construction documents and 3D representation of my entire project
using AutoDesk Ar
chitecture and 3DSMax. These skills will be helpful as I advance in the field of
Construction Management and as BIM becomes the ultimate tool to manage projects from design to
construction.




BIM in the Battlefield

Anticipated Research Leader:
Corey Berry

OBJECTIVE

My objective is to produce a prototype heads up display system capable of retrieving
BIM information
associated with a building location by permanently emplaced RFID tags. This information will be
displayed in a heads
-
up display (HUD) allowing
rapid hands free retrieval of BIM data such as the
location of fuse boxes, available entry ways and important sub
-
structures.

Simple voice commands will
allow the operator to find the desired data embedded in the BIM model.

The hardware technology needed

for this project already exists but it needs to be coupled with software

and widely used BIM models

to make it a complete system.

The main focus of this project will involve
synchronization of RFID hardware, lookup and retrieval of
BIM

datasets

associate
d with each RFID key,
the display of

useful results from the BIM data and
the design

a hands free
voice recognition search
function that
will be easy to comprehend and operate.

DELIVERABLES

The primary deliverable for this project are course materials (50 pages) for a 1/2 day workshops for BIM
adoption by Construction Managers associated with ERDC which matches the goals and needs for
USACE. This material will be delivered in one or more 1/2

day workshops at sites to be determined by
USACE CAD
-
BIM center.

The secondary deliverables are intermediate quarterly progress reports, a BIM for ERDC Construction
Managers action plan (30 pages), 1 hour presentation of action plan at USACE CAD
-
BIM cent
er or other
selected venue and a final report (50 pages) documenting all activities.


APPROACH

This project will be a multi
-
stage approach to designing the full scale prototype.
An overview of each
stage is as follows:





Phase 1

will involve a basic test
ing of hardware features and limits. During this phase a RFID will be
synchronized with a regular computer and will transmit data to the computer. Validation steps will occur
during this phase to test such things as maximum range, data transfer speed and b
asic RF interference.

Phase 2

will commence after any problems that occurred in Phase 1 are solved. During this phase the
implementation of the Heads up Display User Interface

(HUDUI) and testing of a data displaying widget
will take place.

Phase 3
, much

like Phase 1, will involve the synchronization between RFID and BIM database. The major
challenge here will be data sending and retrieval speed.

Phase 4

will integrate the current systems with the VGA Goggles and test everything together with real
RFID sensors located in various buildings.

Resource

Description

RFID Transmitter

Located in the building this device will send data to the soldier from the BIM

database.

RFID Receiver

The soldier will have a receiver unit that is constantly scanning for a signal from
any RFID in range.

VGA Goggles

Needed in step 4 to allow for solider to be hands free.

Nano ITX Computer

This unit will basically be a backpack

mounted system connected to the VGA
Goggles. It will contain the RFID Receiver.

Software Development
Tools

Various open
-
source development tools.

DELIVERABLES

The primary

deliverable for this project is an Open Source
system of software
(written in
.NET
)
and
recommended hardware
which (1)
reads BIM model and sub
-
object codes from emplaced RFID tags
using a portable RFID reader
, (2)
locates the BIM model information in data
base running on a portable
micro
-
processor
, (3)
displays BIM
-
derived data on an augmented reality display
, (4) provides
voice
search through identified BIM data
, and (5)
is specifically designed as an extensible building block for
more complex applications
. The software package will have an install script and preset demo.

The secondary deliverables are intermediate quarterly progress reports, a 1/2 day workshop
presentation to introduce the completed tool and a final report (50 pages) documenting all activ
ities.

BENEFITS/INNOVATION

There are many benefits to having BIM data lookup capabilities on the battlefield. It will provide
soldiers with vital information about pot
entially hostile buildings and
help them in understanding what
may or may not be the
best way to enter or leave a building.

This project will benefit the ACE

CAD
-
BIM center

by providing them with a hardware device that could
be used for many BIM data gathering operations. The results from this project are important to ACE,
because it will

increase their knowledge and capabilities about
projects such as these. There a
r
e

not
many mainstream projects that tie together real
-
time heads up display data acquisition with BIM
database models.

PERSONAL EXPERIENCE AND GOALS


This project will involve

as much software engineering as it will hardware engineering. Although
my area of expertise has revolved around the creation of software tools, I have some experience with
building customized circuits and interfaces for use on multiple computer systems. I

believe this prior
exposure to hardware programming and my general interest in expanding my knowledge in new areas
will help guide me to making this a successful project.






Mobile BIM Annotation

Anticipa
ted Research Leader: Trey McSwey
n

OBJECTIVE

To uti
lize existing SMS
text
messaging
systems to provide an easy way to annotate BIM models remotely
from mobile phones. The objective of the resulting tool would be to help USACE keep BIM models up to
date with “as built” modification to the original building

design. Once a working prototype was
developed the focus would shift to study the workflow which would help and encourage construction
managers to utilize the new tool.

APPROACH

The objective of this proposed project is to use existing mobile text messa
ging systems to quickly
develop a working protot
ype which can be field tested and modified to meet the needs found “on the
ground.” As such
,

the project will proceed with the following steps:

Identification of Initial Target BIM Repository
: Many commerci
al packages including Bentley
and Revit offer internet
-
reachable BIM repositories. One of these commercial packages will be
selected with the help of the ACE CAB
-
BIM center as the initial target of mobile BIM annotation.

Definition of Annotation Subset
:
With the help and input of the ACE CAD
-
BIM center categories
of potentially important “as built” annotations will be indentified and a small
texting language
which incorporates commonly used abbreviations and jargon will be developed.

Development of
“TwitterBIM” Bridge
: Twitter

is a technology which posts SMS text messages
to the owner’s twitter web page.
TwitterBIM will accept t
witter posts in the right format
and
will add corresponding text annotations

to the correct BIM model in the internet
-
reach
able
repository
. T
hus allowing easy annotation
of BIM models
from anywhere in the world
.
Adoption
of Twitter as the bridge for the initial prototype should move the project forward quickly, but

is
possible that after field testing it may be decided to mov
e towards custom software that copies
some of the useful features of Twitter but has additional features to more closely match the
needs of the USACE.

Field Testing:

The objective of this project is to produce a tool which is actually used worldwide.
As s
uch, field testing and study of the barriers to acceptance are critical. With the help of Dr.
Sulbaran and USACE CAD
-
BIM center the working prototype will be tested on actual job sites to
determine what modification or additional features are needed to ma
ke the tool more widely
used by Construction Managers.






DELIVERABLES

The primary deliverable for this project is an Open Source system of software (written in Ruby on Rails)
which (1) provides a sign
-
up workflow for new users of TwitterBIM, (2) provides
workflow to begin a
new TwitterBIM project,
and
(3) provides automated annotation of BIM models in a commercial
internet
-
reachable repository through the use of simple STS cell phone text messages. The software
package will have an install script and prese
t demo.

The secondary deliverables are intermediate quarterly progress reports,
a report (25 pages) on the field
testing of the developed tool with recommendations for additional features to increase usage,
a 1/2 day
workshop presentation to introduce the
completed tool and a final report (50 pages) documenting all
activities.

BENEFITS

BIM techniques are now widely used in the design of buildings for USACE. The goal of this project is to
help push the use of BIM into the construction process
.

Regular ann
otation of BIM models to produce
the “as built” version will help USACE assess completed buildings


contractual and code compliance and
will lead to greater usage of BIM models during building maintenance by raising confidence in the
accuracy of embedded
information.

PERSONAL GOALS

My personal goals are to (1) complete my Master’s in Computer Science

at USM
, (2) develop a tool
which is widely used by USACE, and (3) develop a relationship with CAD
-
BIM personnel which may lead
to a research
-
oriented job wh
ere
I can work on interesting projects and

can help people worldwide.













BIM TeleEngineering

Anticipated Research Leader:
Isaiah Williams

OBJECTIVE

To utilize virtual reality software, such as RealXtend
/OS
-
BEST
, to provide a platform that allows
Department of Defense (DOD) personnel, dep
loyed worldwide, the ability to provide a rapid solution to
problems that arise in the field. Also, to provide a meeting place where subject matter experts can meet
to discuss and develop new BIM models. Finally, t
o provide a mechanism in which troops can be linked
to various subject matter experts to obtain detailed analysis of complex problems that would be difficult
to achieve with the limited expertise or computation capabilities available in the field.

APPROACH

In order to achieve the platform that is outlined above I am purposing that a collections of RealXtend
servers be implemented in what is known as grid mode. Grid mode provides a flexible framework that
allows for several virtual regions to be hosted among

different servers. Each of these servers would be
configured to optimal settings for the given problem it is be used to address. The various modifiable
configurations include physic engine, scripting engine, and several others. Finally, through the use of

RealXtend, an open source software package, any needed modifications to the server
-
client software
can be made and deployed.

The given milestones for this approach would be the initial build and tuning of the hosting servers, the
installation and configur
ation of RealXtend Server, and finally the address any custom modifications.
Through the implementation and continual use of this platform we will be able to identify any problems
with this approach and make adjustments as necessary.

DELIVERABLES

The prim
ary deliverable for this project is an Open Source system of software (written in C#, C++ and
CG) which (1) provides the capacity to host or join virtual BIM
-
design "lockdown" meetings with
participants from around the world, (2) provides meeting schedulin
g and useful attendance features,
and (3) provides additional data import features such as USGS GIS data. The software package will have
an install script and preset demo.

The secondary deliverables are intermediate quarterly progress reports, a 1/2 day wo
rkshop
presentation to introduce the completed tool and a final report (50 pages) documenting all activities.

BENEFITS/INNOVATION

Currently subject matter experts from around the world are flown in to meet and develop new BIM
models. This methodology of d
evelopment is not a cost effective model, and can be enhanced through
the implementation
of this virtual reality environment. Through this project the two enhancements that
will be seen is that the models will already be in a virtual reality environment re
ady to be implement in


order projects such as BIM asset management. Also, in that this platform will provide a cost effective
mechanism in which more subject matter experts can meet and develop.

PERSONAL EXPERIENCE AND GOALS

Currently I am the administrato
r of the RealXtend grid, OS Best Grid, being hosted by the University of
Southern Mississippi. Through the experience of configuring and maintaining the grid for the university I
have had a chance to grasp a better understanding of the inner workings of th
e technology and how
best to implement it. Furthermore, my experience as a Systems Administrator, for the university, and
education in computer science has given me an edge and desire to solve problems.




















Presenting 5D BIMs Using

a
Specialized Video Editing Tool

Anticipated Research Leader:
Lewis Jones

OBJECTIVE

When observing demo and promotional videos for various 5D BIMs, one will notice that for the most
part they are bland and uninteresting. The focus of this project is to desi
gn and create a specialized
video editing tool for the Army Corps of Engineers (ACE) that can be used to create more interesting
videos for various 5D BIM projects while still displaying the same information. The tool will make the
process of piecing toget
her a demo or promotional video quick and easy by doing most of the work for
the user such as recording fly
-
throughs of 5D BIMs with just a few clicks of the mouse and generating
statistics displays based on the information within the 5D BIMs. With the vid
eos being more interesting,
potential funders will be more likely to follow through with the projects.

APPROACH

The first step in this project will be to decide on an open
-
source video editor to build upon. The main
idea is to design the specialized video
editing tool as a plug
-
in for the existing video editor. The second
step is to design the plug
-
in, incorporating any specific requests the ACE may have regarding the look of
the plug
-
in or the options it will offer. This plug
-
in will allow the user to impo
rt 5D BIM models to work
with, recording and generating what the user wants with just a few mouse clicks. Model fly
-
throughs will
be created by the plug
-
in rather than forcing the user to move the camera around themselves, and the
information within the mo
dels will be used to create overlay displays in the videos at the user’s
discretion. The user will also have the option to record voice
-
overs for the video. The third step would
be to create the plug
-
in and program in the different 5D BIM interactions and
editing options. In order
to use the tool a user would only need to download and install the open
-
source video editor, followed
by this project’s plug
-
in, and then import a 5D BIM. Designing a tool that is quick and easy to use is key
to this project.

DELI
VERABLES

The primary deliverable for this project is an Open Source system of software including
a
custom plug
-
in
for BIM 5D Movie Editing which (1) provides the capacity to import BIM models including embedded
data, (2) provides
"director" functions which

combine visual 3D elements, sequences of construction
steps and embedded data
, and (3) provides
typical video editing features such as key frame and voice
over editing
. The software package will have an install script and preset demo.

The secondary delive
rables are intermediate quarterly progress reports, a
20
-
40 minute demonstration
video showing the tools new capabilities

and a final report (50 pages) documenting all activities.

BENEFITS/INNOVATION

The tool that this project proposes to create would be beneficial to the ACE for several reasons. First, it
will do most of the video creation and editing for the user instead of forcing them to spend hours


recording screen captures and meticulously piecin
g together clips and transitions like many media
editors do. Second, it will be easy to use by narrowing down most options into only a few mouse clicks
with a simple user interface. Finally, and most importantly, it will make demo and promotional videos
mo
re interesting than simply rotating around a model as it constructs itself and then displaying some
information. Potential funders would be more impressed when presented with the videos and therefore
more likely to follow through with a project.

PERSONAL E
XPERIENCE

Some personal experience involves a project carried out for an Honors thesis. In that project, entitled
“Improving the Understanding and Experience of Construction Students through Virtual Reality
Environments,” an educational construction game w
as created within the Second Life virtual reality
environment in response to the lack of realistic experience construction students have with building
processes and project management as they begin their careers. Users were provided with a heads
-
up
display

(HUD) that showed buttons labeled with different construction tasks. If the users selected the
construction tasks in the correct sequences, they would see a building gradually appear within the
environment. The users could walk through the building while
they play, observing the different
components from every angle as they appeared. Some other personal experience includes editing
together various videos. One video in particular, created as the final assignment of a class group project,
is currently being
used as promotional media for the USM School of Computing.
















Virtual BIM Code Compliance

Anticipated Research Leader: Lacey Duckworth

OBJECTIVE

The focus of this project is to develop a BIM Code Compliance tool for a virtual environment. This
will
allow construction management people to load a building model into a virtual environment, and
determine if the building complies with OSHA standards. There are two main components in completing
this project, a virtual environment and an object orient
ed programming language. The virtual
environment is to allow the user to view the building model in 3D and the object
-
oriented programming
language is where all code is implemented in order to determine the code compliance.


APPROACH


In order to complete

the project, it has been broken into three phases. The first phase, importing a BIM
into a virtual environment, is where the process of bringing the BIMs into the virtual environment will be
determined. The second phase, coding the OSHA standards is whe
re the Code Compliance rules will be
implemented in the object
-
oriented language. The last phase will be connecting the object oriented
language to the virtual reality BIM so that when the construction manager walks through the building,
the various walls
, slabs, pipes, etc. can be inspected for code compliance.

DELIVERABLES

The primary deliverable for this project is an Open Source system of software (written in C#, C++ and
CG) which (1) provides the capacity to load both BIM models and code compliance sp
ecification files into
virtual reality, (2) provides collaborative viewing of "pop
-
up" code compliance warnings in Virtual
Reality, and (3) provides export of code
-
compliance warnings and group
-
recommended actions as a
report. The software package will hav
e an install script and preset demo.

The secondary deliverables are intermediate quarterly progress reports, a 1/2 day workshop
presentation to introduce the completed tool and a final report (50 pages) documenting all activities.

BENEFITS/INNOVATION

This

project will benefit the ACE by notifying construction management of non
-
code compliance before
construction begins. This project would also help save money as it is more expensive to have to destruct
a building the construct it appropriately. The tool d
eveloped from completion of this project is
important to ACE, because it provides a way not only to envision the construction site, but ensure the
terms under code compliance are met.

PERSONAL GOALS

As a graduate student in the Doctorial program at the University of Southern Mississippi, I have had
experience in various object
-
oriented programming languages as well as model development in a virtual
reality environment. My dissertation topic focuses o
n this topic as I am trying to develop a


communication protocol between virtual reality environments and an object oriented language. My test
case for ensuring that developing such a communication protocol is possible is similar to the BIM code
compliance

project proposed above. The test case is a tutorial for students at the University of Perdue
which provides the user interacting in the virtual environment with the soil type and site measurements,
and asks them to determine the soil type and method for
digging the slab according to OSHA standards.
This project would be a bigger test case to ensure the communication protocol developed works as
hypothesized.
