Contractor

Improved Coordination

Potential Innovation

• Limited in proposals“Prescriptive”30 Alternatives – developed a “No Fly Zone”

• Construction – MPTSchedule offer 5 months less than anticipated in RFP

• CHP NegotiationBetter steam control with condenserArrangement 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 HybridGI 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

success6. 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
