• MPT – 95% designed
• CHP – design in progress
• FDF – design completed
• Coordination
UtilitiesCranesGeotechnical InformationWeekly meetings – Internal and Intra-ContractorCFA meetings
• Partnering – MPT/CHP
Coordination of design/construction and Intra-Contractor
Improved Coordination

Potential Innovation
• Limited in proposals
“Prescriptive”
30 Alternatives – developed a “No Fly Zone”
• Construction – MPT
Schedule offer 5 months less than anticipated in RFP
• CHP Negotiation
Better steam control with condenser
Arrangement of equipment
Innovation accepted if not already vetted by Owner
3
CHP Not Part of DC Water Expertise
• CHP – different review philosophy
Owner – smaller review group, interested in interfaces, and “were not going to operate it”
DBO – “We have to operate it, so we want to make changes
PM/CM – find the balance to get full contract value and understanding
• DC Water recognizing benefit of when DB is appropriate
4
Lessons Learned To Date
• Owner likes to be able to short list 3 qualified proposers• First time Design Build
Owner and Engineers need to take time to understand process
• Design issues come to head early• Design Build Joint Venture = skin in the game• 3D modeling understanding accelerates• Regulatory dust should be settled• Start-up and Commissioning – start early• “Haz Ops” meeting very important• Prescriptiveness can serve “mature” Owners well• Performance guarantees force designer and contractor
to work together and could be a key to being less prescriptive

Vision
Anacostia River Projects Potomac & Rock Creek Projects
DC Water is Implementing Tunnels
Most severely impacted by CSOs
There is a brief window of time to
consider new approaches
Green Gray Hybrid
GI will provide additional CSO control
13
Why is a Multi Million Dollar Demonstration Project Necessary?
Need it to be a large scale demonstration – address entire subsewersheds
Representative sites - not “cherry picked” so scale-up is realistic
Sound technical basis
Potential for innovative solutions and creative alliances
Targeted performance is high degree of CSO control
Resolution of institutional issues
Analysis of other factors• Triple bottom line benefits• Public acceptability• Testing over several meteorological /
climate cycles• O&M impacts
The magnitude of investment by DC ratepayers to control Potomac and Rock Creek CSOs requires a sound technical and institutional
basis for making decisions
14
Demonstration Project (6 sites)
Completed evaluation of sites for GI demonstration projects in Potomac River and Rock Creek sewer sheds.
After construction, monitor for 2 years Use results to design Potomac River and Rock Creek projects
using combination of tunnels and GI
15
Lessons Learned
1. Verify Financial Capabilities• Evaluate need to compare proposers’ financial capabilities
with respect to estimated cash flow needs
2. Process Projects• Designer needs a “skin in the game,” possibly as a JV partner
16
3.RFQ Content/Solicitation• Set a realistic page count; identify what pages
do/do not count • Avoid requests requiring subjectivity or similar
responses among proposers• Include standard forms in RFQ for simpler
organization/evaluation• When answering questions, send responses to all
proposers
4.RFQ Evaluation• Have technical staff at selection panel
discussions to answer questions• Obtain completed score sheets before selection
panel adjourns
Lessons Learned
17
Lessons Learned
5. Contents of Technical Proposal• Resist requesting more items; identify points that differentiate
better schedule, better quality, less risk
• Avoid asking for identical things in different sections• Ask key personnel to list only what contributes to project
success
6. Confidentiality• Emphasize confidentiality among all teams; require signed
agreements• Don’t put confidential evaluations/comments on shared
computer drives• Don’t meet with individual proposers after release of RFQ;
exceptions are official proprietary meetings• Be careful what is printed to shared printers
