Formwork is molds into which concrete or similar materials are either precast or cast-in-place. In the context of concrete construction, the falsework supports the shuttering molds. In specialty applications formwork may be permanently incorporated into the final structure, adding insulation or helping reinforce the finished structure.

An engineering drawing is a type of technical drawing that is used to convey information about an object. A common use is to specify the geometry necessary for the construction of a component and is called a detail drawing .
Formwork is used in concrete construction as the frame for a structure in which fresh concrete is poured to then harden and take on the desired shape. [6] Aesthetic of concrete surfaces can be varied with different formwork sheathing (e.g. board shuttering, smooth formwork, form liner, form moulds, filter fleeces). The type of material used to ...
It was during the year 1910 that Martin M. Foss, a traveling representative of the newly organized McGraw-Hill Book Company, in calling on the Department of Engineering Drawing, recognized in the group headed by Professor Thomas E. French one of the most successful and talented groups in its field in the United States.
For a ground-bearing slab, the formwork may consist only of side walls pushed into the ground. For a suspended slab, the formwork is shaped like a tray, often supported by a temporary scaffold until the concrete sets. The formwork is commonly built from wooden planks and boards, plastic, or steel.
This polystyrene insulated concrete form is cut away to show the inner structure of the formwork and the reinforcing bar (rebar). The cavity is filled with concrete to create the permanent wall. Insulating concrete forms or insulated concrete forms (ICF) are a building system to create reinforced concrete walls or floors with integral insulation.
The metal commonly used is iron or some type of steel, and the mesh is made with wire with a diameter between 0.5 mm and 1 mm. The cement is typically a very rich mix of sand and cement in a 3:1 ratio; when used for making boards, no gravel is used, so that the material is not concrete.
