In most cases, forms and shores should only be removed after the concrete has enough strength to support its weight and imposed loads. Strength can be either pre-determined in construction plans so that certain parameters are met, or strength can be determined by testing with an ASTM method designed to indicate compressive strength.

Open cut or direct bury is the traditional and most common method of pipe installation. The pipe is installed into a trench excavated from the existing ground surface.
