electranet is the principal transmission network service provider in South
australia. to improve the efficiency and accuracy of the detailed design
of construction projects, the company needed to improve the substation
drafting environment. the aUd 350,000 implementation project provided
in-house training to internal staff and external design partners, and created an
electranet library based on existing design templates and standards.
the stricter adherence to design standards will have a direct cost-benefit with
more accurate project estimates, precise bills of materials, and faster progress
toward construction. Bentley Substation was selected to enable the existing
resource base to deliver more accurate detail drawings faster and at less cost.
as a result, capital expenditure requirements will be reduced.

Suspended Power Line Route Planning
Hokkaido and Tsugaru Peninsulas, Japan
after the earthquake of march 11, 2011, Japan suffered a severe electricity
shortage that resulted in planned power outages. In response, the power
distribution grid is being revised to provide a stable electricity supply.
rebuilding the 50- to 100-year-old transmission line towers is urgent, so to
quickly study potential tower routes, Hokkaido aero asahi obtained detailed 3d
data using aerial laser measurements for this Jpy 10. 39 million project.
lidar data was processed using microStation with terraScan and
terramodeler. the laser point-cloud data was then used to calculate current
and future timber heights, conduct offset simulations with virtual power lines,
and estimate the amount of timber to be cut at installation locations. route
selection time and cost were halved compared to conventional on-site survey
