Intelligent Design & Construction (IDC)

Delivery of 3D Projects

What is IDC?

3D engineered modeling is a relatively new and developing technology that can provide

numerous benefits to owners, engineers, contractors, and the general public.

Intelligent Design and Construction

Also known as

Model Based Design for Construction

Why Use 3D Engineered Models ?

• Safety

• Save Time and Money

• Increased Efficiency In Design (no plan sheets)

• Increased Efficiency In Construction

• Clash Detection

• Asset Management

• Reduction in unforeseen conditions & change orders

• Improved Bid Prices

• A complete 3D engineered model includes the base

survey data, proposed horizontal and vertical

alignments, and proposed features and structures

model

• A complete 3D engineered model includes the base

survey data, proposed horizontal and vertical alignments,

and proposed features and structures model.

• The use of 3D engineered modeling has a major

benefit during early design stages versus traditional

2D methods because 3D technologies can easily

make alignment and profile modifications without the

need to manually compute earthwork, right-of-way

impacts, and other design elements.

• Establishing a life cycle project workflow should always be

the starting point for IDC Delivery.

Use By Project TeamsPreconstruction and Design

Using a the CMGC delivery method for

the first project allows the department

to gain the insight of contractors,

supplier and subs.

Clash detection greatly

improves the designer’s ability to detect utility conflicts and

clashes early, allowing for avoidance or greater time to relocate

utilities.

General Public/Property and Utility Owners

3D engineered models provide a convenient way for the

general public and affected property and utility owners to visualize

the project prior to construction.

Use By Project Teams

Requiring the contractors to provide the

department construction crews with the

use and training of the survey equipment

provides onsite education

• Contractors will embrace the 3D project delivery, as

this allows them preform qty take off and

verifications. Contractors build models anyway• As with all AMG-equipped machinery, the contractor

will need to upload the 3D engineered model into the

AMG systems

• A fully designed 3D engineered model contains the

proposed grading surface and proposed features, and

it is able to guide grading machines and excavators

when they are referenced to control points set up on or

near the project site.

• Contractors have been using this technology for years,

creating a 3D Design model streamlines the

construction process and contributes to better pricing

on bid day due to early phasing and mot planning.

• Risk mitigation is a key result of 3D Project

delivery. Contractors do not take risk, they price

them

Contractors, Subs and Suppliers

• Introduction to

industry is

important

• Project Preview

• Contractor

• I-Pad Plan Room

Timeline2014 – 2017

2014INVESTIGATION & PLANNING

IDC: UDOT names the effort Intelligent Design and Construction

Trip to Iowa: UDOT investigated how electronic files are made available to contractors

Workshop: FHWA 3D Engineered Models for Construction Workshop held


3D Engineered Model for Construction Workshop goals :

IDC Implementation Plans• Short-term (May-Dec '14) - Investigation and

Planning

• Mid-term (Jan-Dec '15) - Award Model as Legal Document on one project (MALD)

• Final (Coming soon) - Award MALD on all projects with models

“For information only” electronic design files provided on 15 projects


Follow-up on 15 projects for lessons-learned:

Risk Workshop followed by Brainstorm Workshop

• UDOT senior leaders, construction, IT, survey, local & national contractors, consultants, academia, software & hardware vendors, local technology companies

• 20 risks identified to awarding MALD


Brainstorm Workshop focus: 2 major risks, 6 other risks• Major Risks: Lack of construction hardware and

software

• Other risks: survey control, design review, modelQC/QA, data compatibility between owner & contractors, small contractors, missing learning opportunities.

2015AWARD MODEL as LEGAL DOCUMENT

SR 20 selected to award MALD• Low-risk passing lane project• Limited ROW, utilities, rural, low ADT• In-house design, Bentley OpenRoads• CMGC delivery to address MALD risk• Developed RFP for CMGC contract

2016MALD AWARD & CONSTRUCTION

UDOT and contractor collaborate on OpenRoads and Trimble models

• Bentley, Trimble, Contractor, UDOT begin bi-weekly meetings to resolve issues

• Three months for Trimble Business Center to match UDOT’s model


Contractors survey had differences with UDOT’s survey:

• Model is updated same day & Contractor loses no time due to electronic file transfer and stakeless/stringlessconstruction

• UDOT Crews & Contractor use OpenRoads Navigator app on mobile devices. Shortcoming: app didn't support cross sections.

• UDOT inspectors use Contractor supplied rovers.


How to convey information to contractor without plans:

• Annotation in 3D

• Embed information in element• SUDA• ECX Attributes/Item

Types• Links

• Saved views for iModel

2016MALD AWARD AND CONSTRUCTION

4. I-80 Blackrock BrIM (Granite)• Initial phases• Project team developing workflows

2017

AWARDING MALD on CMGC

Objective: How to move forward with IDC/elimination of plan sheets

• Seven contractors, Internal UDOT design, consultant designers, UDOT construction crews, GIS, Facilitator (Greg Evans SiTech)• Informal discussion for contractor feedback.

• Takeaways: • Trimble/Bentley very appreciative of

information gathered

Management

Understanding the current tools

available for your 3D project

delivery is important.

Consideration for internal

reviews and how they will be

conducted without plan sets is

important.

The model does allow for

standard details or

specifications to be placed in the

model associated with an

element.

Review of current standards and

specification will need to take

place prior to delivery. These will

need to be modified to address

3D survey requirements, as build
