Project Overview

The 187-room Grand Bohemian, developed by the Florida-based Kessler Collection faced several issues with the site that would challenge its targeted opening date. Being built in the popular downtown community of Greenville, SC, the hotel will feature 30 balcony suites, a luxury spa, restaurant, bar, and indoor and outdoor event spaces. A 1:1 slope from the base of the hotel leading down to the flood-prone Reedy River needed protection from erosion and potential shallow sliding. Any failure of the embankment could cause exposure to the rammed aggregate piers that support the hotel.

Solution

The original specification called for S8 Aluminum anchors driven to a depth of 16’. During the installation process, many previously unidentified obstructions were encountered. It was determined that the slope was filled with debris from an old textile mill. A smaller Platipus S6 Cast Iron anchor, driven to a depth of 13’, was more efficient in penetrating the varying slope conditions. To stabilize the embankment, all anchors were loaded between 4,000 to 6,000 lbs. (depending on depth) successfully securing double twist PVC coated wire mesh with erosion control matting supplied by Maccaferri – USA.

Project Overview

To provide much-needed access to two remote parking lots at Winston Salem State University, a bridge was built to cross an existing rail line and connect the lots to the main campus. The owner of the railroad, Norfolk Southern, would not allow the newly built bridge to be accessed until an adjacent abutment that had begun to slough was reinforced. The railroad felt there was a risk that the vibrations caused by passing trains could lead to a shallow plane failure.

Solution

The Platipus ARGS^® (Anchor Reinforced Grid Solutions) system was specified by a local Geotechnical Engineer who was very experienced in the local geology of the Piedmont region. Summit Design and Engineering performed a global stability analysis and concluded that the depth of failure was between 5 –10 feet deep. The design included a grid patterned of 2 TN anchors driven to a minimum depth of 15′ and pre-tensioned to 2,000 lbs. After all the anchors were loaded, the slope was covered in a 4” thick reinforced concrete face. The anchors were subsequently tensioned one last time to the concrete face once it had cured.
