A lean-to shelter is a simplified free-standing version of a wilderness hut with three solid walls and a single- or, in the case of an Adirondack lean-to, offset-pitched gable roof. The open side is commonly oriented away from the prevailing weather. Often it is made of rough logs or unfinished wood and used for camping.
Poles, from which these buildings get their name, are natural shaped or round wooden timbers 4 to 12 inches (100 to 300 mm) in diameter. [4] The structural frame of a pole building is made of tree trunks, utility poles, engineered lumber or chemically pressure-treated squared timbers which may be buried in the ground or anchored to a concrete slab.
Lean approach tries to make continuous improvements in the process, workflows and product; [19] whereas PMI approach doesn't pay that much attention to continuous improvement. In lean construction, decision making is distributed in design production control systems; [20] by comparison, in PMI decision making is centered to one manager some times.
Stamped concrete is an architectural concrete that has a superior surface finish. After a concrete floor has been laid, floor hardeners (can be pigmented) are impregnated on the surface and a mold that may be textured to replicate a stone / brick or even wood is stamped on to give an attractive textured surface finish.

For a small to medium project, the cost and time of hiring mixing equipment, labour, plus purchase and storage for the ingredients of concrete, added to environmental concerns (cement dust is an airborne health hazard) [10] may simply be not worthwhile when compared to the cost of ready-mixed concrete, where the customer pays for what they use ...
Concrete has a very low coefficient of thermal expansion, and as it matures concrete shrinks. All concrete structures will crack to some extent, due to shrinkage and tension. Concrete which is subjected to long-duration forces is prone to creep. The density of concrete varies, but is around 2,400 kilograms per cubic metre (150 lb/cu ft). [1]
