2. gcsBarriers™ are another
extension of the powerful
GCS™ technologies

3. gcsBarrier™
On Duty
The Colorado Rockfall
Simulation Program (CRSP)
was used to determine
height of this gcsBarrier™.
Note the slope grading
uphill of the gcsBarrier™
to control bounding heights
of incoming rocks

11. Design and Construction of a gcsBarrier™ is the same 1, 2, 3 process
used for Walls, Abutments, Piers and Deflection barriers ---
Two rows of CMUs, a lift of granular backfill and a sheet of geofabric.

15. Elegant Combination of a
GCS™ Box Culvert Design
As a Portal for a Mine Entry
And
An Elevated, Thickened GSC™
Wall as a gcsBarrier™ for
Rockfall Protection

16. ROCKFALL PROTECTION ON I-70
Designed by Barrett for Colorado DOT
This GCS™ Wall is 26 feet high and has
A 30 foot wide rockfall catchment
Bench on top.
This GCS™ Wall has a truncated base.
The bottom geofabrics are only
3 feet wide, and progress to 30 feet
at the top. Very efficient – unlike MSE
we avoided excavation of bedrock
at the base.
This wall was carefully monitored.
Shown here is CDOT’s John David –
john.david@dot.state.co.us -
CDOT’s project manager. Deflection was
Less than ½ inch and strains in the
Geofabric were less than ½%, which is
Typical for GCS™ performance.

17. INDEED,
IT CAUGHT
A ROCK!

18. 15 million Foot Pounds of Energy
(it was nuked!)

19. ONLY MINOR DAMAGE

20. QUICK AND EASY REPAIR

21. OTHER APPLICATIONS
MUDFLOW DEFLECTION

FOR
AVALANCHE DEFLECTION

FOR
AVALANCHE DEFLECTION

24. THIS SUITE OF SLIDES SHOWING gcsBarriers™
SERVES TO ILLUSTRATE THE
VERSATILITY AND ADAPTABILITY
OF THE POWERFUL GCS™ TECHNOLOGIES.
THESE EXAMPLES ARE COMPELLING
REASONS TO BEGIN THE TRANSITION
FROM MSE TO GRS/GCS™ CONCEPTS.
MSE WAS A TRANSITIONAL STEP
AND IT HAS SERVED ITS PURPOSE.
