Brayman
Construction Corp., headquartered outside of Pittsburgh, Pa., provided a
diverse range of products and services for the fast-track SR-28 project in
Etna, Pa. Brayman is a full-service provider of general and specialty
geotechnical design/build solutions throughout the eastern United States. The
photo shown depicts the firm’s installation of 225 permanent rock anchors for
the $2.2 million retaining wall project. The rock anchors were drilled using conventional
crawler-mounted rigs and hanging-platform rigs.
While the main focus of the work was on the installation of 225 permanent rock
anchors, mainline wall rock anchors were installed working multiple rigs and
multiple shifts, including Saturdays and Sundays, in order to meet the
Pennsylvania Department of Transportation’s scheduled completion date. As part
of the temporary support bridge, Brayman installed 56 95⁄8-inch-diameter
micropiles. The firm also performed temporary excavation support consisting of
soil nailing and driven beams with wood lagging.
In addition to this application, Brayman’s Foundation Division offers multiple
diverse foundation applications including micropiles, caissons, driven/drilled
piles, ground anchors/tiebacks, underpinning, and tiebacks, to name just a few.
