In architecture, a core is a vertical space used for circulation and services. It may also be referred to as a circulation core or service core. A core may include staircases, elevators, electrical cables, water pipes and risers. A core allows people to move between the floors of a building, and distributes services efficiently to the floors.
System Modules (originally known as System Building Blocks; the name was changed around 1961) are a DEC modular digital logic family which preceded the later FLIP CHIPs. [1] They connect to the units they are plugged into via a set of 22 gold-plated discrete pins along one edge.
Mechanical floors are generally counted in the building's floor numbering (this is required by some building codes) but are accessed only by service elevators. Some zoning regulations exclude mechanical floors from a building's maximum area calculation, permitting a significant increase in building sizes; this is the case in New York City. [1]
Piled raft underpinning systems are commonly used when an entire building needs to be underpinned. The internal floors are completely removed, a grid of piles is installed, and a reinforced concrete raft is then constructed over the complete floor level, picking up and fully supporting all external and internal walls.
They are an important building block in analog control systems, and can also be used in digital control. Given the control plant, desired specifications can be achieved using compensators. I, P , PI , PD , and PID , are optimizing controllers which are used to improve system parameters (such as reducing steady state error, reducing resonant ...
External access point for fire sprinkler and dry standpipe at a building in San Francisco, US Antique wet standpipe preserved at Edison and Ford Winter Estates. A standpipe or riser is a type of rigid water piping which is built into multi-story buildings in a vertical position, or into bridges in a horizontal position, to which fire hoses can be connected, allowing manual application of water ...

Also called caissons, drilled shafts, drilled piers, cast-in-drilled-hole piles (CIDH piles) or cast-in-situ piles, a borehole is drilled into the ground, then concrete (and often some sort of reinforcing) is placed into the borehole to form the pile. Rotary boring techniques allow larger diameter piles than any other piling method and permit ...
