The Port of Melbourne Channel Deepening Project required dredging around essential gas, oil, and sewage pipelines in the Yarra River. Simply deepening the river would reduce cover over the pipelines and risk damage from ship traffic. Boskalis proposed a novel protection system using steel plates and precisely placed rock to safely protect the pipelines during dredging. Special equipment was modified and tested to allow extremely accurate placement of the protective structures within the limited space above the pipelines. Through cooperation between stakeholders, an innovative solution was successfully implemented to deepen the channel while fully protecting vital utility lines.
Effective water management is critical to both open-pit and sub-surface mining operations. Mine dewatering is an essential part of resource extraction, as it lowers the water table around the mine or quarry. Effectively managed dewatering processes typically employ continuous water level monitoring.
After significant deformation and rotting due to excess water collection occurred on Highway 35 in Owatonna, MN, Tensar's RoaDrain was used because it was equipped at keeping the base aggregates dry and the compressive strength of RoaDrain would be sufficient for long term serviceability.

By adapting ethnographic research methods, designers can better understand, empathize and operate within the communities they serve. This session will illuminate the potential of ethnography for design and instigate new creative practices toward place-based awareness.
A restorative future is dependent on place-based design and thus dependent on new architectural approaches to understanding the dimensions of place; x,y,z, + time + culture. The workshop will be personal, communal and catalytic, offering an introduction to both ethnographic and autoethnographic research. Attendees will be asked to access their sensory memories and spatial imaginations resulting in a collection of qualitative narratives reflecting the ephemeral natures of the places in which they live. The collaboration will demonstrate that ethnographic methods develop and reinforce one’s capacity for empathy as well as strengthen valuable reflective, creative, and associative thinking skills.

Whitescape Civil Engineering Case StudyAndrew White
Civil engineering is the foundation of every successful construction project, and a major factor in maximising the commercial value to landowners, developers and investors. Complex infrastructure projects of any scale need intelligent solutions to resolve the challenges. For sites that present special technical issues, the civil engineering contribution can make a material difference to financial returns.
Protection against falling rock masses with extremely high energy levels is not feasible with rockfall barriers. Maccaferri has therefore developed rockfall embankments made of Terramesh, which are able to withstand extremely high energy levels
1. INTRODUCTION
Part of the Port of Melbourne Channel
DeepeningProject was to dredge the Yarra River,
the last section of the Channel before arriving at
Swanson Dock where the container terminals are
located.
The Yarra River is crossed by steel service
pipelines for gas (30” / 0.75 m) and oil (24”/
0.60 m) and a concrete sewage tunnel of 3-m
diameter. These services pipelines are essential to
the city of Melbourne and had to remain ‘live’, i.e.
operational during the deepening works. By
deepening the river, however, the existing cover
on these services pipelines would no longer
adequately protect against possible anchor drop
and drag and scour of the riverbed caused by the
return current and propeller wash of passing ships.
CHALLENGES
A new means of protection for the services
pipelineswas necessary. The initial Port of
Melbourne Corporation (PoMC) protection plan
was to relocate the pipelines to a deeper level.
Unfortunately, building a new concrete sewage
tunnel and installing 2 pipelines in the river’s
complicated soil conditions would make the the
construction of new crossings especially difficult
and at inordinate expense.
As a Partner in the PoMC Alliance Team, Boskalis
proposed a novel protection system using plate
and rock placement that was far more attractive
and financially viable. But this too presented
challenges. Given that the allowable construction
height(protection layer thickness) above the
services pipelines was very limited, the usual
practise of pipeline protection by depositing a
layer of loose rock was not possible; a tailor-made
design had to be created.
