Space was the first challenge at this location. The site had room for an office building, but not for access next to the railway tracks.

In addition, pressure for project completion meant construction would begin before water utility work was done and it was determined that an existing mechanically stabilised earth structure (MSE) on the site wouldn’t be able to carry the additional projected load.


By choosing the Anchor Landmark system, the engineer had the desired high-strength, mechanical connection at the face of the high-load-bearing wall that held up the roadway.

Designing the wall so it surrounded a water main rather than burying the line allowed construction to proceed before work began on water utilities.

Unique to the Anchor Landmark system, is the incorporation of a horizontal core enabling the use of structural steel in the face for direct anchorage.

By using grouted-earth-anchor tiebacks attached to steel walers running through the Landmark core, the engineer relieved pressure on the existing MSE and stabilized the structure. When the 200 metre wall was completed, the site had a stable access road, subsequent water utility work didn’t undermine the wall, and the existing MSE was stabilised.
