Britannia Secondary School, Vancouver, British Columbia, Canada

In order to meet modern requirements on earthquake safety, this 70 year old building needed to be retrofitted. The designer chose high capacity Ø57 mm DCP GEWI ^® Piles.
Restricted by the low ceiling height in the building, the 15 m deep, ø 140 mm boreholes were drilled with a track-mounted hydraulic mini-drilling rig.
The anchors were coupled in sections from 2.7 m to 4 m.
The tight restrictions of 2.7 m headroom, 0.60 m spacing at the pile head and pile inclinations of up to 40°, posed no problem for this very flexible installation method.
