Agenda

• Building Information Modeling (BIM) – An Introduction

• From BIM to Civil Integrated Management (CIM)

• Applications of CIM – 3D/4D Modeling for TxDOT projects

• NCHRP 10-96: Guide for CIM at DOTs


Introduction

• Building Information Model (BIM)– “a digital representation of physical and functional characteristics of a

facility” (NBIMS 2014)

• BIM integration with project delivery becoming more common in building industry– Model-based cost estimating, scheduling– Model-based progress monitoring, activity analysis– Building systems clash detection (Mechanical, electrical, plumbing,

HVAC, Fire.)– As-built data collection– Energy performance analysis…

BIM for highway infrastructure?

• Applications to highway sector relatively new– Identified as a potential area with benefits

BUILDING INFORMATION MODELING

TO

CIVIL INTEGRATED MANAGEMENT (CIM)


BIM for Highways – Unique Challenges

• Highway sector has specific challenges– Limiting public procurement framework– Large Horizontal footprint (Modeling boundary)– Major earthwork - higher degrees of uncertainty and less modeling

precision– Increased coordination with external stakeholders

• ROW acquisition• Utility companies and communities/businesses in neighborhoods• Public Information (commuters)

• Document-based workflow – Diminishes utility of electronic data (source)– Causes difficulties in public outreach efforts, design reviews, conflict

analysis, constructability reviews, construction processes


BIM for Highways – Unique Challenges• Utilizing BIM can assist in

Public Information, Visualization (nD) Design coordination (utilities), Constructability analysis

Automated Machine Guidance (AMG) Site logistics, Work area Management Asset and inventory management

BIM functions and benefits not isolated!interdependent and share synergestic benefits and challenges, with several other technologies relevant for lifecycle

An overarching Implementation framework for digital project delivery and asset management vital for agencies (Departments of Transportation)• Factor the unique challenges and lifecycle interdependences• Need to consider the digital workflow (CIM)


Definition of CIM

“Civil Integrated Management (CIM) is the technology-enabled collection, organization, managed accessibility, and the use of accurate data and information throughout the life cycle of a transportation asset. The concept may be used by all affected parties for a wide range of purposes, including planning, environmental assessment, surveying, construction, maintenance, asset management, and risk assessment.”

APPLICATIONS OF CIVIL INTEGRATED MANAGEMENT (CIM) –

ILLUSTRATIVE PROJECTS FOR 3-D/4-D MODELING (TxDOT)


Woodall Rodgers Deck Plaza project Issues examined: Complexity, productivity analysis in beam placement Visualization of lane closures


President George Bush Turnpike and I -30Issues examined: • 4D simulation for schedule analysis• Constructability reviews – ROW acquisition, utility relocation, design/planning issues.


Dallas Horseshoe ProjectIssues examined: • Parametric 3D modeling and 4D simulation – Terrain, Highways, bridges • Enhanced design visualization (rendering and animations)

NCHRP 10-96: GUIDE FOR CIM AT DOTS

OBJECTIVE, METHODOLOGY, AND GUIDEBOOK DEVELOPMENT


NCHRP 10-96 Team members

• The University of Texas at Austin– William O’Brien – Principal Investigator– Fernanda Leite – Co-Principal Investigator– Nabeel Khwaja – Co-Principal Investigator– Bharathwaj Sankaran – Graduate Student– Ignacio De Sande Palma – Graduate Student

• The University of Colorado at Boulder– Paul Goodrum – Co-Principal Investigator– Keith Molenaar – Co-Principal Investigator– Guillermo Nevett – Graduate Student– Joshua Johnson – Graduate Student


Research Objectives

The objective of this research is to develop a guide to CIM that DOT managers can use toa) Identify which CIM tools and processes to

implement;b) Identify the particular benefits, obstacles, and

costs; andc) Identify practical strategies to assist with

implementation.


Methodology

National Surveys

• Agency surveys: Organizational issues (standards, contracts, legal issues, agency-level CIM utilization, benefits, costs)

• Project surveys: Project-level performance improvements, challenges, identification of case studies for detailed analysis

Case studies

• Detailed interview of projects that demonstrated successful utilization of one or more CIM practices

• Identify practical strategies, lessons learned, and recommendations

CIM Guide

• identify practical strategies and propose framework for increasing reliance on digital project delivery and asset management


Scope of CIM tools


CIM Tools Affect Many Functions

Each CIM tool improves the performance, predictability or transparency in executing one or more CIM functions.


CIM Guidebook

• NCHRP 10-96 Guidebook includes an implementation framework for CIM at Department of Transportation

• Provides integrated view of CIM tools and functions to support agency-level planning for investments in CIM

• Supplements available guidelines and case examples of specific CIM functions at the agency


CIM – Maturity Model• NCHRP 10-96 provides

an implementation maturity model to help assess current capabilities and next steps

• Use the maturity model to plan and better connect CIM initiatives across the agency

CIM Implementation Maturity Model: NCHRP 10-96 Guidebook


CIM Implementation Considerations• CIM implementation should be a planned effort

– Consider agency goals and capabilities– Consider existing investments in CIM technologies and functions

• CIM is not just about the technology – consider:– Project delivery strategies– Standards and specifications– Training needs and culture– Governance and policy– Information management

• CIM should have implementation champions

• CIM initiatives should have provision for lessons learned


NCHRP 10-96 CIM Guide – Layout

• Identifies CIM tools and related functions for project delivery, their uses and benefits

• Proposes a three-stage framework for integrating CIM with agency workflow

• Compiles illustrative and case examples to demonstrate the framework

Introduction• Overview of CIM tools and functions

CIMworkflow

• Impact of CIM on project delivery

Framework

• Planning of current capabilities (maturity model)• Assessment of future needs (costs-benefit analysis)• Implementation considerations ( best practices)

Resources

• Literature review • Current state of practice (Surveys)• Case studies (lessons learned)

Appendix• CIM resources/references
