MPT – 95% designedCHP – design in progressFDF – design completedCoordinationUtilitiesCranesGeotechnical InformationWeekly meetings – Internal and Intra-ContractorCFA meetingsPartnering – 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 – MPTSchedule offer 5 months less than anticipated in RFPCHP NegotiationBetter steam control with condenserArrangement of equipment Innovation accepted if not already vetted by Owner
CHP Not Part of DC Water Expertise CHP – different review philosophyOwner – smaller review group, interested in interfaces, and “were not going to operate it”DBO – “We have to operate it, so we want to make changesPM/CM – find the balance to get full contract value and understanding DC Water recognizing benefit of when DB is appropriate
Lessons Learned To Date Owner likes to be able to short list 3 qualified proposersFirst time Design BuildOwner and Engineers need to take time to understand processDesign issues come to head earlyDesign Build Joint Venture = skin in the game3D modeling understanding acceleratesRegulatory dust should be settledStart-up and Commissioning – start early“Haz Ops” meeting very important Prescriptiveness can serve “mature” Owners wellPerformance guarantees force designer and contractor to work together and could be a key to being less prescriptive

Vision Anacostia River ProjectsPotomac & 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
Why is a Multi Million Dollar Demonstration Project Necessary?Need it to be a large scale demonstration – address entire subsewershedsRepresentative sites - not “cherry picked” so scale-up is realisticSound technical basisPotential for innovative solutions and creative alliancesTargeted performance is high degree of CSO control Resolution of institutional issuesAnalysis of other factorsTriple bottom line benefitsPublic acceptabilityTesting over several meteorological / climate cyclesO&M impactsThe magnitude of investment by DC ratepayers to control Potomac and Rock Creek CSOs requires a sound technical and institutional basis for making decisions
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 yearsUse results to design Potomac River and Rock Creek projects using combination of tunnels and GI
Lessons Learned Verify Financial CapabilitiesEvaluate need to compare proposers’ financial capabilities with respect to estimated cash flow needsProcess Projects Designer needs a “skin in the game,” possibly as a JV partner
RFQ Content/Solicitation Set a realistic page count; identify what pages do/do not count Avoid requests requiring subjectivity or similar responses among proposersInclude standard forms in RFQ for simpler organization/evaluationWhen answering questions, send responses to all proposersRFQ EvaluationHave technical staff at selection panel discussions to answer questionsObtain completed score sheets before selection panel adjournsLessons Learned
Lessons Learned Contents of Technical ProposalResist requesting more items; identify points that differentiate better schedule, better quality, less riskAvoid asking for identical things in different sectionsAsk key personnel to list only what contributes to project success ConfidentialityEmphasize 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
