Post-tensioned concrete is everywhere in California parking structures, podium buildings, office floors and slab-on-grade homes. Before anyone saws or drills into it, the tendons have to be found.
Core drilling is how contractors put clean, round holes through concrete slabs, walls and decks for pipe, conduit, ductwork and anchors, without breaking out more concrete than the hole needs.
Concrete removal is quoted from the actual scope, but the price always comes down to the same handful of factors. Here is what they are and how to get an accurate number.
Most demolition in a built-out city isn't a whole building coming down. It is a tenant space stripped to the shell, a wall opened up, or a floor removed while the rest of the building stays in service.
In California, demolition starts on paper. Here is the typical sequence of permits, surveys and notifications, with the Southern California air district rules most projects in Los Angeles, Orange, Riverside and San Bernardino Counties fall under.
Concrete cutting isn't one tool. The method depends on whether the concrete is horizontal or vertical, how thick it is, and how much room there is to work.
