• What is the difference between tiltwall construction, tilt-up panel construction and pre-cast concrete construction? (see the link for “precast concrete”)
==In some regions the term tiltwall is used interchangeably with the term tilt-up. Tilt wall is a compound word using the terms "tilt-up" and concrete "wall" panels. The building's walls are poured directly at the jobsite in large slabs of concrete called "tilt-up panels" or "tiltwall panels".==

Allows general contractors to build a wide range of commercial buildings more quickly and with lower construction costs.
==Precast concrete buildings are buildings constructed using precast or prefabricated concrete wall panels.This prefabricated panel process, provides a more controlled environment for consistent quality.==
