King Cove Road Project is a new 18 mile long road project located
in Aleutians East Burrough, Alaska. The project connects the community
of the King Cove to an all weather airport located in Cold Bay and
provides the residents a much needed year round 24-7 emergency
ingress/egress. The project negotiates several major fish stream
crossings with 10 bridges up to 120 feet in length and 9 fish passage
culverts up to 12 feet diameter. Approximately 5 miles of the road
were constructed in the summer of 2004 and the remaining road sections
are scheduled to be constructed the summer of 2005.
The project was bid as a design-build team consisting of SKW/Eskimos,
Inc. with Nathan Powell as the overall project manager. PND, Inc was
contracted by SKW to serve as the engineering design consultant.
The
first 3-miles of the road were designed by PND using Land Development
Desktop (LDD). This portion of the project was considered the simplest
due to the relatively gently sloping terrain and side borrow type
construction methods used by the contractor. The remaining road
segments, however, were situated on variable terrain including 40%
side slopes and a long segment located on the beach paralleling Cold
Bay for approximately 1.5 miles. Design of these road segments were
much more challenging and required a program with more finesse and
real time mass haul to evaluate alignment options quickly and
efficiently. PND selected Softree due to its user friendly graphical
interface and its ability to have the profile, plan, section and mass
haul windows open all at the same time. The learning curve was
fast on the program and the end result was a road design that required
less time to prepare than thought possible while accurately tracking
quantities in real time.
The program is just what is needed in this
type of application and compared to LDD saved time and was easier to
use.
