Cryptoporticus
In Ancient Roman architecture a cryptoporticus (from Latin crypta and porticus) is a covered corridor or passageway. The usual English is "cryptoportico". The cryptoportico is a semi-subterranean gallery whose vaulting supports portico structures aboveground and which is lit from openings at the tops of its arches. On sloping sites the cryptoporticus is often partially at ground level and supports a structure such as a forum or Roman villa, in which case it served as basis villae. It is often vaulted and lit by openings in the vault. In the letters of Pliny the Younger, the term is ...
Chandrashala
Chandrashala is the term most often used to describe the circular or horseshoe arch that decorates so many Indian cave temples and shrines. The arch is shaped like the cross-section of a barrel vault. When used on the facade of a chaitya hall, it is called a chaitya arch. It is sometimes called a gavaksha (or kudu, in Tamil) when used as a decorative element on a structural temple.
Cancellarii
Cancelli are lattice-work, placed before a window, a door-way, the tribunal of a judge, or any other place. Hence the occupation of Cancellarius, which originally signified a porter who stood at the latticed or grated door of the emperor's palace. The emperor Carinus gave great dissatisfaction by promoting one of his Cancellarii to be Praefectus urbi. The cancellarius also signified a legal scribe or secretary, who sat within the cancelli or lattice-work, by which the crowd was kept off from the tribunals of the judges.
Cantilever
A cantilever is a beam supported on only one end. The beam carries the load to the support where it is resisted by moment and shear stress. Cantilever construction allows for overhanging structures without external bracing. Cantilevers can also be constructed with trusses or slabs. This is in contrast to a simply supported beam such as those found in a post and lintel system. A simply supported beam is supported at both ends with loads applied between the supports. Cantilevers are widely found in construction, notably in cantilever bridges and balconies (see corbel). In cantilever bridges the cantilevers ...
Casement window
A casement window (or casement) is a window that is attached to its frame by one or more hinges. Casement windows typically are hinged at the side, sometimes at the top or bottom. They are used singly or in pairs within a common frame, in which case they are hinged on the outside. Casement windows were the most common house window before the sash window was introduced, and usually contain leaded glass. These casement windows usually were hinged on the side, and opened inward. The windows were covered by functional exterior shutters, which opened outward.

Fire alarm system
An automatic fire alarm system is designed to detect the unwanted presence of fire by monitoring environmental changes associated with combustion. In general, a fire alarm system is either classified as automatic, manually activated, or both. Automatic fire alarm systems can be used to notify people to evacuate in the event of a fire or other emergency,... [Read more...]
Passive fire protection
Passive fire protection (PFP) is an integral component of the three components of structural fire protection and fire safety in a building. PFP attempts to contain fires or slow the spread, through use of fire resistant walls, floors, and doors (amongst other examples). PFP systems must comply with the associated Listing and approval use and compliance... [Read more...]

Sprinkler System Benefits
Fire sprinklers are most effective during the fire’s initial flame growth stage. A properly selected sprinkler will detect the fire’s heat, initiate alarm and begin suppression within moments after flames appear. In most instances sprinklers will control fire advancement within a few minutes of their activation. This will in turn result... [Read more...]
Fire sprinkler system
A fire sprinkler system is an active fire protection measure, consisting of a water supply, providing adequate pressure and flowrate to a water distribution piping system, onto which fire sprinklers are connected.
