3D CADD/4D CADD 

Doreen Bartoldus, CCM, PE

3D CADD / 4D CADD

2D Coordination

3D CADD

3D CADD and the Construction Process 

• Also used during scheduling meetings to view 

mobilization conflicts “how can we build this scenarios”

Croton 3D Model 

• Croton WTP - Overview


• Section Cut looking North


• Pipe Gallery

CAT/DEL UV 3D Model 

• UV Reactors

3D CADD - Project Administration 

Review of 3D Model resulted in a “Clash 

List” and new procedures were developed 

to address the use of this tool 

1) First thing said was that initial 

quick review showed that 

Clash List was mostly 

“ re-location, not re-design…”

3D CADD - Project Administration 

• Clash List developed and reviewed per schedule priority 

(CPM and Drawing Coordination) 

• Only one “clash” has resulted in a change order so far 

• HVAC Coordination ongoing (avoiding future conflicts)

CatDel UV 3D Model 

• Picture to be added

• Walkthrough Video to be added

Converting 3D Model to 4D Model 

• Contractor utilizing BIM technology 

for scheduling


• 3D model 

• Production planning, activity plans 

• Visual understanding 

• 4D model 

• Schedule QA/QC - Simulate project 

• Optimize sequencing 

• Coordinate Crane usage (critical activities) 

• Visualize actual site situation at any given point in time

Digital Photography 

Management 

Paul Whitener, PE

Digital Photography Management 

Challenge:


• Need efficient retrieval of photographs for: 

• Reports / Documentation 

• Augment Technical Descriptions (RFI’s, RFC’s, 

Correspondence) 

• Claims / Investigations 

• Presentations / Publicity / Public Relations


Performance Requirements: 

• Annotations on photographs to highlight 

specific observations within an image to 

support: 

• Punchlist / Warranty Items 

• Defective Work / Inspection Items 

• Interferences 

• Investigations 

• Access by all CM staff, subconsultants 

and DEP project personnel


Performance Requirements: 

• Complete security of original image 

• Numerous user-defined attribute fields to 

allow for efficient photo retrieval using 

keyword search 

• Efficient archiving and distribution of 

individual image files 

• Prefer that many different digital input 

sources could be supported so that project 

staff was not limited to one, or just a few, 

camera manufacturers

Solution: 

LYNX Digital Photo Management System

Lynx Digital Photo Management 

• Used in a variety of construction, governmental and law 

enforcement applications 

• Allows for centralized access, security and backup 

• Numerous user-defined fields allow attributes to be 

associated with each photo to facilitate retrieval using 

keyword search features 

• Multiple licenses allow simultaneous access to the photo 

database by several project team members 

• Compressed image files for archival and 

distribution efficiency 

• Annotations may be added and saved to an image without 

adulterating the original image file


• Acquire Images from Digital Source


• Assign Attributes to Images


• Image with Attributes and Notes Attached


• Image Data Captured Directly from Camera


• Notations Overlaid on Photos


• Zoom and Annotate Details


• Visual and Voice Notes Attached to Image


• User Specified Search Criteria

SOURCE Data Access 

Paul Whitener, PE

Program Data Management: 

Challenge


Performance Requirements 

• One data entry point – preferably 

the Field Inspectors on a daily 

basis as a byproduct of 

producing their daily reports 

• Robust enough to support $1.4B 

of construction and 22 inspectors 

over the course of 5 years 

• Information captured at the point 

of installation but made available 

to Primavera, Excel and other 

application software


Performance Requirements 

• WBS / reports / formatting 

customizable to the 

Cat/Del UV project 

• Data must reside on project 

server for centralized data 

storage / retrieval / maintenance, 

security and backup 

• Must integrate with, or at least 

not clash with, the CMIS system 

being used on the project

Solution: 

SOURCE Data Management

SOURCE Data Management 

• Developed by CH2M HILL specifically for contract 

management on large capital programs 

• SOURCE was developed as a program management 

tool, it is well suited for the long time horizons, multiple 

phases and the numerous contracts found on the 

Cat/Del UV Facility project 

• SOURCE is a suite of tools 

• The Quantity Data Management module within SOURCE 

augments the Malcolm Pirnie developed CMIS, customized for 

NYC DEP mega-projects, without duplicating functionality


• SOURCE is written around MS Access database 

software, therefore: 

• Open code customizable for the specific program / 

application 

• Data is usable by Primavera, Excel, Word and other 

common application software 

• Reports are customizable as is level of detail: 

Executive summary level reporting is available as is 

any specified degree of detail 

• Quantities and daily report data are searchable using 

keywords and user-defined attributes

Inspector daily reports are input into database through SOURCE 

template on inspectors PC

Daily progress of the work as reported in daily reports will 

include links to installed quantities of materials

Single Daily Report – As Submitted

Daily Inspections – Reporting Menu 

Filter / Search 

Capability: User 

can select for 

specific time frame, 

items, or vendors 

or any combination 

desired

All Pay Items 

converted to 

dollars, 

summarized by 

month
