"Cob stitch" repair on old traditional cob cottage in Devon, England Maison de Jeanne, Sévérac-le-Château. Timber and cob construction. Cob is an English term attested to around the year 1600 [3] for an ancient building material that has been used for building since prehistoric times. The use of this material in Iran is more than 4000 years old.
COBie was developed by Bill East, of the US Army Corps of Engineers, while at the Construction Engineering Research Laboratory in 2007. [3] The project was funded with an initial grant from the US National Aeronautics and Space Administration and the White House Office of Science and Technology Policy (through National Institute of Standards and Technology).
The amount of and type of each material in the mixture used leads to different styles of buildings. The deciding factor is usually connected with the quality of the soil being used. Larger amounts of clay are usually employed in building with cob, while low-clay soil is usually associated with sod house or sod roof construction.
A USBR soil scientist advances a Giddings Probe direct push soil sampler.. Geotechnical investigations are performed by geotechnical engineers or engineering geologists to obtain information on the physical properties of soil earthworks and foundations for proposed structures and for repair of distress to earthworks and structures caused by subsurface conditions; this type of investigation is ...
A compressed earth block (CEB), also known as a pressed earth block or a compressed soil block, is a building material made primarily from an appropriate mix of fairly dry inorganic subsoil, non-expansive clay, sand, and aggregate. Forming compressed earth blocks requires dampening, mechanically pressing at high pressure, and then drying the ...
Construction management (CM) aims to control the quality of a construction project's scope, time, and cost (sometimes referred to as a project management triangle or "triple constraints") to maximize the project owner's satisfaction.
A soil stockpile is formed with excavated topsoil during the construction of buildings or infrastructure. It is considered to be an important resource in construction and ecology . [ 1 ] [ 2 ] Soil is stockpiled for later use in landscaping or restoration of the region following the removal of construction infrastructure. [ 3 ]
Since soil is a widely available material, it has been used in construction since prehistory. It may be combined with other materials, compressed and/or baked to add strength. Soil is still an economical material for many applications, and may have low environmental impact both during and after construction.
