Planning, Design, and Construction of Peripheral Ring Road for Bangalore City india international infrastructure
FINALIST
The $185 million Peripheral Ring Road project encompasses
the southern part of Bangalore City, India, connecting seven
major radial roads consisting of three national highways,
three state highways, and an expressway. The proposed
41-kilometer access-controlled peripheral road is a four-lane
highway with a median of 11. 4 meters and expandability
to six lanes.
Using MXROAD, STAAD.Pro, MicroStation GeoGraphics,
and other Bentley solutions, the firm was able to calculate
alignment on virgin land with the least impact on the environ-
ment, satisfy the requirements of full access control, test
alternatives for horizontal and vertical alignment quickly,
generate drawings automatically, perform surface analysis,
and the list goes on. Whether a complex interchange design,
alignment design, profiles, cross sections, drainage design,
or earthwork volumes, the project team used one platform
from design to construction. Savings from this approach
totaled $11.9 million.
Norra Länken s Weco
FINALIST
Norra Länken is a three-kilometer, four-lane highway tunnel in
northern Stockholm, Sweden. It is the next link in the circular
highway system already underway around the city. The
estimated construction time is eight years and estimated cost
is $1 billion.
This was the first job where SWECO’s client, the Swedish
Road Administration, specified in the contract that all design
be done in 3D, so one of the essential goals for this project
was to develop a procedure for 3D design that could link
all design disciplines. Engineers and designers from the
various disciplines worked on their preferred CAD platform,
including MicroStation and AutoCAD. MicroStation then
provided the necessary interoperability to reference DGN
and DWG files to one 3D master file.
