A safe place provides a final refuge from a fire, such as a road or open space at the end of an exit. It can also be a temporary “haven” or “refuge” to protect people while they are evacuating during a fire. The term is only used in the Performance Requirements. Safe places can be inside or outside a building, and must provide a person with protection from a fire and then allow them to safely escape to a road or open space. Example: fire-isolated stairways; fire-isolated ramps; fire-isolated passageways; and an adjacent fire compartment.

Sound Absorption, Sound Reverberation,
Smooth surfaces in a room tend to reflect high frequency sound. Hard surfaces like concrete and timber can increase this sound reflection or reverberation.Sound absorption is the ability of a material to absorb sound within a room. Sound absorbent materials such as drapes or carpet are commonly used to reduce sound reflections or echoes. Sound absorption can improve the sound quality within a room. Sound absorptive materials are also useful within internal cavities of double skin partitions or hanging ceiling constructions. They help absorb sound within the cavity, reducing noise through the building element. Efficient sound absorbers in cavities are typically made from glass wool, rock wool, polyester fibre, natural wool or cellulose fibre. These materials are often used for sound and thermal insulation. The ability of a surface material to reduce sound reflection (sound absorption) is not the same as its ability to control noise passing through from the adjoining residence above (sound insulation). It is important to make this distinction when choosing materials. High mass, dense and well sealed materials generally offer improved sound insulation.
Sound proofing a wall or subfloor, generally with fibreglass insulation.Sound Insulation Sound insulation refers to the ability of a material to stop or reduce airborne sound. High mass, dense and well sealed materials generally offer improved sound insulation.Internal Sound Insulation is important when designing a wall (or other partition) to stop noise passing through from an adjoining room.
External Sound Insulation refers to the ability of materials to reduce sound transmitting into or from a building. Good external sound insulation is important when designing and constructing the external elements of a building. This includes walls, windows, doors, ventilation and roofing. Good acoustic design uses a combination of sound absorption (to reduce sound reflections within a room) and sound insulation (to stop sound transmitting into or from a room).

An uninterrupted series of steps.
The area of a floor near the top or bottom step of a stair. An intermediate landing is a small platform that is built as part of the stair between main floor levels and is typically used to allow stairs to change directions, or to allow the user a rest.
The leading edge of treads of stairs and of landings at the top of stairway flights.
The vertical portion between each tread on the stair. This may be missing for an “open” stair effect
Carpeting that runs down the middle of the stairs. Runners may be directly stapled or nailed to the stairs, or may be secured by specialized bar that holds the carpet in place where the tread meets the riser.
If there is not another flight of stairs immediately underneath, the triangular space underneath the stairs is called a “spandrel”. It is frequently used as a closet.
The part of the stairway that is stepped on. It is constructed to the same specifications (thickness) as any other flooring. The tread “width” is measured from the outer edge of the step to the vertical “riser” between steps.
For curved stairs, the inner radius of the curve may result in very narrow treads. The “walkline” is the imaginary line some distance away from the inner edge on which people are expected to walk. Building code will specify the distance. Building codes will then specify the minimum tread size at the walkline.
Winders are steps that are narrower on one side than the other. They are used to change the direction of the stairs without landings. A series of winders form a circular or spiral stairway. When three steps are used to turn a 90° corner, the middle step is called a kite winder as a kite-shaped quadrilateral.
Stair Winder (Quarter Landing)
A tread that is constructed within a landing and is non-parallel, only permissible in “private stairs”.
The stairs themselves: the steps, railings and landings; though often it is used interchangeably with “stairs” and “stairway”. In the UK, however, the term “staircase” denotes what in the U.S. is called “stairway”, but usually includes the casing – the walls, banisters and underside of the stairs or roof above.
The following is a list of stair terminology:
- Baluster/Spindle – The vertical member, plain or decorative, that acts as the infill between the handrail and baserail (or tread if cut string).
- Balustrading – The collective name for the complete assembly of handrails, base-rails, newels, spindles and caps.
- Bullnose Step – Usually at the bottom of the stairs with one or both ends of the step having a quarter circle design.
- Closed String – A string with the face housed/trenched to accommodate treads and risers so their profile cannot be seen.
- Continuous Handrail – Using straight lengths of handrail connected to handrail fittings and ramps, the handrail flows over the tops of newel turnings creating a continuous run of handrail.
- Curtail Step – A decorative shaped step at the bottom of the stairs usually accommodating the volute and volute newel turning of the Continuous Handrail System.
- Cut or Open String – A string with the upper edge cut away to the shape of the treads and risers so that their profile can be seen from the side.
- Going – The going of a flight of stairs is the horizontal distance between the face of the first and last risers. The individual going of a step is measured from face of riser to face of riser.
- Newel – Accommodates the strings, handrails and treads/risers of stairs.
- Nosing – The edge of the tread projecting beyond the face of the riser and the face of a cut string.
- Pitch – The angle between the pitch line and the horizontal.
- Pitch Line – the notional line connecting the nosings of all treads in a flight of stairs.
- Rake – The pitch of the stairs.
- Rise – The rise of a flight is the vertical distance between the floors or landings connected by the flight. The individual rise is the vertical measurement from top of tread to top of tread.
- Riser – The board that forms the face of the step.
- Staircase – The entire structure relating to a stair, comprising steps, treads, risers, strings, balustrading, landings etc.
- Stairway/Stairwell – The space/void provided for the stairs.
- Step – The tread and riser combined.

Starting Step or Bullnose
Where stairs are open on one or both sides, the first step above the lower floor may be wider than the other steps and rounded. The balusters typically form a semi-circle around the circumference of the rounded portion and the handrail has a horizontal spiral called a “volute” that supports the top of the balusters. Besides the cosmetic appeal, starting steps allow the balusters to form a wider, more stable base for the end of the handrail. Handrails that simply end at a post at the foot of the stairs can be less sturdy, even with a thick post. A double bullnose can be used when both sides of the stairs are open.

Trim (e.g. quarter-round or baseboard trim) is normally applied where walls meet floors and often underneath treads to hide the reveal where the tread and riser meet. Shoe moulding may be used between where the lower floor and the first riser meet. Trimming a starting step is a special challenge as the last riser above the lower floor is rounded. Today, special flexible, plastic trim is available for this purpose, however wooden mouldings are still used and are either cut from a single piece of rounded wood, or bent with laminations Scotia is concave moulding that is underneath the nosing between the riser and the tread above it.

String or Stringer
The supporting member for stair treads. The structural member that supports the treads and risers. There are typically two stringers, one on either side of the stairs; though the treads may be supported many other ways. The stringers are sometimes notched so that the risers and treads fit into them. Stringers on open-sided stairs are often open themselves so that the treads are visible from the side. Such stringers are called “cut” stringers. Stringers on a closed side of the stairs are closed, with the support for the treads routed into the stringer.

Structural engineering is a branch of engineering which deals with the analysis and design of various structural systems. Although this branch of engineering has influence on various other disciplines like mechanical or aeronautical engineering, etc it is more commonly identified with civil engineering.Structural engineering mainly involves two activities Structural Analysis Structural Design Structural analysis deals with analyzing a particular structural system. A structural system may vary from simple systems (like beams, columns, slabs, etc) to more complex systems (like frames, bridges, piers, foundations, retaining walls, etc). The objective behind analysis is to estimate or find resultant stresses (or forces) so that these elements can be designed to withstand the load that comes over it.Structural Design is a process of selecting a member of required dimensions such that they provide adequate stability under service loads. There are two main conditions to consider in Structural Engineering. One is stability, and the other is serviceability.
