Construction English Dictionary
 

 
Listen in to any conversation with a person working in the construction industry and you will probably hear some common words that may have different meanings and some words that sound made up. Even conversations between subcontractors and general contractors can become confusing when jargon from a specific area differs from broader construction communication. 

To help clarify the words that may be thrown around out there in the world, here is an ongoing list for your reference. 
 

Definitions:


Acoustical:
providing some sound protection. 
  • See also: Non-acoustical
Airwall: a moveable wall that consists of a track system attached within the ceiling and panels that contain an air-supported bladder. 
  • See also: Operable Wall, Operable Partition, Folding Panel Partition
As-Built Drawings: final version shop drawings that shows exactly how the wall was/is built. 
  • See also: Final Fabrication Drawings
Black Core Phenolic: a type of toilet compartment that is created when weighted layers of cotton, paper or glass fabric mix are placed under heat and pressure and filled with synthetic resin. The inner material of a phenolic compartment is black in color. This material is scratch and graffiti resistant and stands up to vandalism problems. It can also take severe moisture conditions from showers, pools, and saunas.
  • See also: Phenolic, Color-Thru Phenolic
Bottom Seal: horizontal barrier located on the bottom of a panel. Bottom seals help to secure the panel into place and help block sound. Bottom seal sizes can range from 1" to 4" in order to accomodate shifting floors. 

Bulb Seal: rubber trim that is attached to the vertical sides of panels. It helps to protect panel edges and creates a secure, tight closure. 

Color-Thru Phenolic: a type of toilet compartment that is created when weighted layers of cotton, paper or glass fabric mix are placed under heat and pressure and filled with synthetic resin. The inner material of a phenolic compartment matches the color on the exterior, which means the color runs all the way through. This material is scratch and graffiti resistant and stands up to vandalism problems. It can also take severe moisture conditions from showers, pools, and saunas.
  • See also: Phenolic, Black Core Phenolic
Crank Tool: metal device that acts as a key to an operable partition. The crank tool sets (locks) and unsets (unlocks) the seals that are on the top and bottom of each panel. 

Escapement: a small removeable section of track that allows installers to thread the panels into the track. 

Final Fabrication Drawings: final version shop drawings that shows exactly how the wall was/is built. 
  • See also: As-Built Drawings
Folding Panel Partition: a moveable wall that consists of a track system attached within the ceiling and panels. 
  • See also: Operable Wall, Operable Partition, Airwall
Horizontal Seals: barriers at located at the top and bottom of each panel that help to set the wall in place and prevent sound transfer. Seals located on top of a panel can be fixed in that you can always see them. Seals on the bottom and sometimes the top also retract into the panel. This allows the panel to move freely. 
  • See also: Top Seal, Bottom Seal
I-Beam: an iron or steel beam that is I-shaped in cross section. 

Individual (Panels): If an operable wall is individual or has individual panels, it means that the panels are not hinged together, each panel hangs by itself. 

Non-acoustical: does not provide any sound protection. 

Operable Partition: a moveable wall that consists of a track system attached within the ceiling and panels. 
  • See also: Operable Wall, Folding Panel Partition, Airwall
Operable Wall: a moveable partition that consists of a track system attached within the ceiling and panels. 
  • See also: Operable Partition, Folding Panel Partition, Airwall
Paired (Panels): If an operable wall is paired or has paired panels, it means that two panels are hinged together like a door or book. 

Panels : rectangular piece of wood, glass, or metal that forms parts of a larger surface such as a door or wall. Panels in an operable partition consist of internal mechanisms and insulation to recreate specific functions and control sound. Panels in a toilet compartment can consist of solid plastic or other similar material, particle board, or cellular honeycomb.

Pass Door: a single or double doors that are set into a panel(s) to allow for people to go from one side of the room to the other. 

Phenolic: is created when weighted layers of cotton, paper or glass fabric mix are placed under heat and pressure and filled with synthetic resin. Toilet compartments made out of phenolic come in black core or color-thru.
  • See also: Black Core Phenolic, Color-Thru phenolic
Pilaster: a rectangular column used as part of a toilet compartment system. 

Pocket: a small room that stores the operable partition when not in use. 

Pocket Door: a two or three-panel door that hides the operable partition from view when not in use. The pocket door is installed at the opening of a pocket storage area. 

Powder Coated Steel: toilet compartment material that features thermoset hybrid powder finish on galvannealed steel. This type of material is resistant to corrosion, grease, acids, caustics, mars, and stains. 

Recover: to replace the wall covering on the face of a operable wall with a new wall covering. 
 
Scope of Work: the work to be performed.

Shop Drawings: a drawing or set of drawings produced by a manufacturer, which illustrates how a product will look as well as details inside and out. These are used by subcontractors and contractors to make sure the product is correct. It also helps different scopes of work to work together to make sure the installation will be safe and accurate.

Solid Plastic (HDPE):
is a polyethylene thermoplastic material made from petroleum. HDPE is commonly recycled and made into composite wood or plastic lumber. HDPE in restrooms is resistent to common cleaning agents, moisture, mildrew, and graffiti. It's ideal for busy public restrooms and/or areas with high humidity. 

STC (Sound Transmission Class rating): 
a score given to a building's surface (wall, ceiling, window, etc.) based on its ability to reduce sound coming through it. STC rating goes from 25 – 65. The higher the rating, the less noise that gets through.

Toilet Compartment:
partitions that separate a space in a toilet room. Each partitioned area contains a toilet or lavatory. Compartments consist of panels, doors, and pilasters.

Track: pieces of molded metal, typically aluminum or steel, that allow a trolley wheel to glide through a channel. Track is attached to a steel I-beam or secured using unistrut. It is one of two main components in an operable partition system.

Trolley: is a wheel attached to the top of a panel that allows the panel to be pushed or pulled down the track. 

Wall Covering: vinyl, fabric, carpet, plastic laminate, or other material that is mounted to the face or a panel. Wall covering is for aesthetic purposes only in most cases.
