Brief introduction
Ecology and technology
Case study
ECOLOGICAL SERVICES AT RAMBOLL
Biologists, ecologists, economists, engineers and natural resource specialists… working with commercial and government clients worldwide to support scientifically sound decisions… and
to promote science and ecology -based strategies supporting environmentally responsible and sustainable business
practices.

MAINE EXPERTISE IN ACTION

Environment consulting has historically emphasized "pollution cleanup".
Post-2008 economic downturn and climate change awareness has shifted focus globally
towards new technologies, substitute chemical products, and less-polluting production processes
that limit the ecology impact of economic activities.
Ecology services are becoming proactive, supporting social and
environmental balance, and based on sustainability and “green” policies and
practices.

Science
Ecotechnology is based on deep understanding of the principles on which the natural environment functions, and the transfer of such principles to solutions that minimize
long-term cost to Society and harm to the global environment…

Composite Infrastructure Fabrication
Challenge
Rehabilitate contaminated cove in urban estuary
Create public access compatible with brownfield re-development
Secure a private – public funding partnership
What we did
Composite infrastructure from Maine
Design engineering from Denmark
Result
Visualized several public walkway options for permitting and regulatory approvalIdentified an affordable, long-term maintenance strategy

SHORELINE PUBLIC WALKWAYNEWARK, NEW JERSEY USA
BASIC CONCEPTUAL DESIGN
The “basic” design layout provides a simple foundation upon which more fanciful features and creative elements could be added
Fundamentally, the walkway must be:
ü Minimally intrusive on tidal flow necessary to support marsh grasses
ü Easy to maintain
ü Visually attractive
ü Safe for use by general public
ü Rugged and able to withstand seasonal hurricane-level wind and tidal forces

WALKWAY OPTIONS

FEASIBILITY
12
Two Options … Bridge should focus on:
• Lighter touch
• Non-linear forms
• Contact with the water and the site’sfeatures
• Low environmental impact
• Short spans
• Ease of construction
Option 1 – Crescent Walkway
Option 2 – Daisy Chain Walkway
OPTION 2 – DAISY CHAIN WALKWAY
13
• 10m dia platforms with 30m+ identical fixed walkway spans
• Circular nodes regularly spaced along route
• All spans constructed off site and brought to site by boat/barge
OPTION 2 – DAISY CHAIN WALKWAY
14
• Approx 180m (570ft) length
• Changing viewpoint along sinuous curved route
• Simple forms and use of materials
• Nodes might include seating, moorings, viewpoints, fishing spots
