Client: The La Jolla High School Expansion Project
The La Jolla High School Expansion Project needed to realign
Fay Avenue with seismic and aesthetic considerations in mind.
The Project opted to install a permanent soil nail wall with
a sculpted finish to blend in with the surrounding environment
and engaged Daley Construction who subcontracted with Condon-Johnson
and Associates (CJA) to produce the soil nail wall.
The wall was up to 15’ high and was retained by a two
tiered system of soil nails. The upper wall was constructed
on a 1:6 batter and the lower wall on a 3/4 :1 batter. Three
rows of soil nails provided soil structure interaction strengthening
for the wall which was over 300’ long. Structural shotcrete,
reinforced for seismic stability, was installed to bridge
between the soil nails.
The finished facing on the wall was sculpted
to look like adjacent sandstone outcrops. The textured face
was stained to a natural sandstone color and then sealed.
The project won the American Society of Civil Engineers (ASCE)
2001 Award of Excellence.
