South Coast Medical Center Wall @ Laguna Beach

Laguna Beach, Calif. PCH

Unique Features:

This project exemplifies many unique features of the Stresswall Product.  The project developer for the South Coast Medical Center Hospital expansion project, Sheldon Pollock in Santa Monica, requested that we provide a wall that would eliminate shoring that would have been required for any other wall option  to support the existing Hospital embankment.

We proposed the “Terrace Wall” counterfort wall option which could be installed w/o shoring. A new building was to be constructed in front of and at a lower elevation than the existing five story structure.  To do this a portion of the sloping embankment in front of the existing center would have to be removed w/o disturbing the existing building (maximum allowed settlement would have to be less than 0.5 inch!

To accomplish this the contractor cut deep slots into the existing slope between the existing deep caisson foundation for the existing structure.  Since the site was is a stones throw from the ocean there is always a risk of morning rains etc. so the contractor was required to provide a site cover to eliminate any potential erosion should storms occur during wall construction.  The slope face was covered every night and over weekends.

Following the slot cutting the contractor placed the open  face counterforts in the slots and backfilled the portion of the counterforts w/in the slot cuts with slurry.  Subsequently the .5 meter wide wall panels were placed in the Terrace Wall reverse batter voids.

Due the the spacing and orientation of the wall panels there is approximately half of the wall face area that could be planted.  By selecting  maintenance free, continuously blooming plants with an emitter irrigation system the concrete members quickly disappeared as the planting matured.  As can be seen from the shots the result is a constantly changing pallet of color instead of a stark industrial look as would be the case for a conventional wall.  In addition, the wall reduces the effect highway and other noise sources which is an advantage for patients in the new structure.

At the request of the ASCE  we presented the Project for their annual meeting due to the unique features and advantages of the counterfort wall system.

Wiley Canyon 40′ Cut Wall

Wiley Canyon Road

Unique Features:

To lengthen the radius of a curve as well as to smooth out the road alignment a cut was required for Wiley Canyon.  To accomplish this without shoring the Stresswall system was selected.  Although the wall face is at a 1:12 batter (essentially vertical) random planting areas within the wall face for internal landscaping options were made possible with the large random planting “pockets” in the wall face.  Plants included both large flowering bushes as well as vines and ivy.

The counterforts were placed in slots cut into the existing embankment so that no shoring was required as would have been the case for other wall options.  Wall cut was utilized for wall fill.

Seawall for SR31 @ the Canadian Border

SR 31 @ Canadian Border

Unique Features:

Single tier seawall structure placed along WashDOT SR31 at the Canadian Border.

The counterforts were placed in slots cut into the existing roadway embankment.  Due to the constant border traffic it was necessary to construct the wall as one lane was kept open.  Other wall options would have required shoring.

Cut material was utilized for wall fill.

Sorrento Valley Alternating Panel Improvement Wall

Sorrento Valley, Calif.

Unique Features:

By utilizing the “slot cut” installation method temporary shoring was eliminated that would have been requires for other wall types.  Therefore the overall wall cost and construction time was greatly reduced compared to other wall options.
