School Safety Preparedness Drill (SSPD) is an annual earthquake preparedness drill being organised in schools of North and North Eastern states of India commemorating 4 April 1905 Kangra earthquake. Two non-governmental organisations, GeoHazards Society (GHS) and GeoHazards International (GHI), have been working for earthquake safety in South ...
Mock-ups are used by designers mainly to acquire feedback from users. Mock-ups address the idea captured in a popular engineering one-liner: "You can fix it now on the drafting board with an eraser or you can fix it later on the construction site with a sledge hammer". [2] Mockups are used as design tools virtually everywhere a new product is ...
Construction site safety is an aspect of construction-related activities concerned with protecting construction site workers and others from death, injury, disease or other health-related risks. Construction is an often hazardous, predominantly land-based activity where site workers may be exposed to various risks, some of which remain ...
A fire drill is a method of practicing how a building should evacuate in the event of a fire or other emergencies. In most cases, the building's existing fire alarm system is activated and the building is evacuated by means of the nearest available exits, as if an emergency had actually occurred.
Typical earthworks include road construction, railway beds, causeways, dams, levees, canals, and berms. Other common earthworks are land grading to reconfigure the topography of a site, or to stabilize slopes. Geofoam is a new lightweight earthworks technique used to build a bridge overpass on weak soil near Montreal.
A 2017 violation arose after a construction worker suffered an injury on a site at 61 Moss Road in Westerville, in which a power buggy fell, and struck and pinned an employee against a wall.
A continuous flight auger drill is used to excavate a hole and concrete is injected through a hollow shaft under pressure as the auger is extracted. Reinforcement is then inserted after the auger is removed. [1] This creates a continuous pile without ever leaving an open hole.
In construction, a pilot hole is a small hole drilled into a piece of construction material. Its purpose may be: to guide a larger drill to the appropriate location and ease the job of the larger drill, allow the insertion of another hole-making tool, such as a knockout punch, that will produce the final-sized hole, or
