Regionalization – A Dredgers Perspective (not THE)

• Important to engage all dredgers in discussion

• Most entrepreneurial business

• Multiple investments amounting to several $100’s of millions dollars even without a commitment.

Regionalization - A Dredger’s Perspective

Foundational Issues (why?)

• Schedule

– Typically time to permit

– Time to contract

• Costs

– Always a question

– Best attitude is what can I do to lower costs?

Regional Sediment Management

- Combining Authorities to do the right thing!

- Beneficial Use of Dredging Material


Cautions

- Include all projects at bid time, don’t piggyback - Have money and permits in place, options add risk - If non-Corps project, focus on boilerplate contract.

Needs to be adaptive for dredging - Engage dredgers early, industry days work

Draft Plans & Specifications


Cautions

- Be flexible on schedules, lots of scheduling issues for dredgers

- Fix dates and priorities if necessary, but understand cost impact.

- Start date unimportant, finish date is important don’t include unnecessary constraints


Cautions

- When owner is engaged, prices drop

- There is no way to increase work requirements and lower costs. Help yourself by being flexible where possible.

- Allow and encourage innovation

- Reduce Risk
