Tilt-up walls are made by pouring concrete into flat forms laid out on the ground.
When the concrete slab has cured, the walls are lifted into a vertical position with a crane.
The bracing holds the solid walls in place until the rest of the structural work is complete.

These underground drainage pipes are very close to the building.
Getting them in the right place before the tilt-up walls go up was
a challenge that our expert plumbers accomplished without problem.

B & I Plumbing Foreman Joe Russell has just put a pressure test
on this underground condensate drain and is ready for inspection.

There will be more than 150 floor drains installed throughout the high school.
The underground piping system is about a mile and a half of PVC pipe.

Some of the plumbing was in remote locations from the main building,
like the locker rooms for the school's athletic program.

Underneath the long narrow plywood planks is an 85-foot trench drain system.
