The type of construction of a building depends on a multitude of considerations, including but not limited to, the building's square footage, number of levels, and occupancy type. The most common and generally used type of cement is Portland cement which is known to have good resistance to cracking and shrinkage. This construction is easy to set up, inexpensive, and structurally sound. Walls, partitions, columns, floors and roofs are noncombustible. It uses lightweight and combustible materials. Even small hotels could fit under the umbrella of Type V construction.The material for this type can be anything allowed by code, but it's usually wood.
