Metro ‘jet grouting’ begins between Rossmore and Lucerne

| September 29, 2016 | 0 Comments

Purple LineMetro and its design-build contractor are starting to work in the median of Wilshire Blvd. across from Hancock Park, Fremont Place, Windsor Square and Windsor Village.

The contractor will be placing K-Rail (concrete barriers) and restriping the center of Wilshire, reducing the street to two lanes in each direction between Rossmore Ave. and Lucerne Blvd. for approximately six to eight weeks.

The work during that time will include saw-cutting, pot-holing, minor street demolition, drilling, use of a generator and a storage silo, and deliveries. This all supports the “jet grouting” of holes drilled into the path of the tunnel-boring machine that is scheduled to begin travel west from Western Ave. in 2018.

What is jet grouting?

Jet grouting reinforces and strengthens the subsurface soil with concrete to support tunneling and cross-passage installation. Jet grouting already is underway between Orange Dr. and Mansfield Ave., and the process will take place in many other locations on Wilshire between Western Ave. and the under-construction La Brea subway station. Jet grouting is scheduled to take place between Lucerne and Windsor Blvds. in November.

Weekday work hours for the jet grouting are from 7 a.m. to 9 p.m. On Saturdays, work hours are from 8 a.m. to 6 p.m.

Metro notes that the city’s Wilshire Bus Rapid Transit (BRT) lane restrictions will not be enforced in these areas during jet grouting.
