CADD the use of computer technology for design and design documentation. CAD software replaces manual

drafting with an automated.

BIM Building information modeling (BIM) is a digital representations of physical and functional characteristics of the

existing and final project allowing design issues to be spotted before construction.

Digital As Built updates to the CADD/BIM models as constructed; location and asset data collected

during and post construction

Digital Twin A digital twin is a digital representation of a physical object. It includes the model of the

physical object, data from the object, a unique one-to-one correspondence to the object and the ability to monitor the object. Digital twins offer strong potential to achieve better insights on their objects and drive better decisions.

FDOT BIM and CADD Standards Benefits


BIM Data Flow DOT


Improve Safety…

Use of AMG - Less time staking projects, work zones are safer,

Better cross slope and superelevation construction quality

Better Staging Plans from BIM, improves work zone / less impacts on drivers

Enhance Mobility…

BIM can help plan detours and scheduling of lane shifts with traffic simulations

BIM helps optimize design and construction of facility assets

Helps visualize solutions ahead and avoid costly mistakes during construction when using legacy plans

Streamline Construction Schedule Highlight who is building what, when each part will be built, the materials to be used and

how it will be constructed

Inspires Innovation

Create an accurate and complete as-built record model for ongoing maintenance, operation and asset management through out

life cycle

Once built, the model becomes a virtual and accurate collection of the asset data used for system wide decision making

Helps to monitor construction schedule and budget

Helps reconcile Final Project Costs

BIM Benefits for FDOT - Vital Few


BIM supports Civil Integrated Management (CIM)

CIM office objective …

Web-based GIS Enterprise Data portal framework fueled by the ROADS Initiative.

ROADS Initiative

readily available and accurate data to make informed decisions.

streamline information across the organization

enable better, faster decision making

removing current barriers that prevent the efficient sharing of information.

Pilot Project Requirements:

• Model as Legal Document - signed and sealed

• Construction requires the use of AMG

• Earthwork

• Pavement (Milling and Overlay)

• Implement NexGen plans to the greatest extent possible

DBB AMG Pilot Projects

DBB AMG/BIM Pilot Projects

Expectations:

• Better Designs

• Plans Production Efficiencies

• Accurate Quantities

• Better Construct Cost Estimates

• Minimize Contractor Claims

• Less Error & Omission Issues

DBB BIM Pilot Projects

Challenges:

• Design Submittal: NexGen Plans and Models (each signed)

• As-builts were done both on pdfs and in model files

• Over the shoulder Design Reviews with Native software

• No defined guidelines for model reviews, currently developing

• Developed procedure for Digitally signing models

• FDOTDigitalSignaturesNativeCADD -YouTube

Start with simple projects, not many complications

focused on specific construction activity (earthwork, paving, milling, overlays)

Organize and scope the model management plan at inception

Make model navigation as simple as possible for non-modeling reviewers

Project Reviewers, CEIs, Estimators, etc.

Lessons Learned (8 Mile Turnpike –RRR )


Signed model delivery eliminates need for the Project Layout sheets in Plans

Employ advanced coordination with the permitting agencies on their needs, preferably before

procurement, so the scope and staff hours can reflect any additional deliverables needed by

the permitting agencies to complete their review and issue the permit.

Employ advanced coordination with the UAOs to prepare them for NexGen plans. The use of

KMZ files could be demonstrated to build a level of comfort with the UAOs and avoid the need

to generate single-use drainage structure cross sections.



Contractor should validate the existing surface before AMG

Make necessary design model changes accordingly

Consider reviewing profiles on controlling 3D breaklines for smoother transitions, not just

controlled by cross sections intervals

Common Data exchange between Design and Construction is needed

XML files are not good enough

Streamline the Digital Signatures workflow for design models



Some Contractors prefer paper prints for the convenience of field staff.

Many contractors are still not ready for digital model delivery

Some are not as eager as others to invest in the technology and training required to make

their staff effective.

More encouragement and collaboration with the construction industry will be required

Contracting industry needs expertise manipulating 3D models and CADD files.
