Faced concrete
To finish the front and all vertical sides of a concrete porch, step(s), or patio. Normally the "face" is broom finished.
Extras
Additional work requested of a contractor, not included in the original plan, which will be billed separately and will not alter the original contract amount, but increase the cost of building the home.
Exposure Pathways
The way in which people are exposed to radiation or other contaminants. The three basic pathways are inhalation (contaminants are taken into the lungs), ingestion (contaminants are swallowed) and direct (external) exposure (contaminants cause damage from outside the body). https://healthymaterialslab.org/tool-guides/hml-resources
Face nail
To install nails into the vertical face of a bearing header or beam.
Extrapolate
To project tested values, assuming a continuity of an established pattern, to obtain values beyond the limit of the test results. Not necessarily reliable.
Exterior Insulation and Finish System
Exterior cladding assembly consisting of a polymer finish over a reinforcement adhered to foam plastic insulation that is fastened to masonry, concrete, building sheathing or directly to the structural framing. The sheathing may be cement board or gypsum sheathing.
Exposure
Contact with a substance through inhalation, ingestion, or dermal absorption. https://healthymaterialslab.org/tool-guides/hml-resources
Extruding
A process in which a billet of material is shaped into a strip having a uniform cross section by forcing the material through a die.
Face Brick
Brick made or selected to produce an attractive exterior wall.
Faceted Glass Window
A window made by bonding 1 inch (25.4 mm) thick glass pieces with an epoxy resin matrix or reinforced concrete.
Fascia
Horizontal boards attached to rafter/truss ends at the eaves and along gables. Roof drain gutters are attached to the fascia. Board fastened to the ends of the rafters or joists forming part of a cornice.
Fahrenheit Temperature
The temperature scale on which. at standard atmospheric pressure. the boiling point of water is 212 degrees Fahrenheit, the freezing point is 32 degrees Fahrenheit, and absolute zero is 2459.69 degrees Fahrenheit.
Fatigue Limit
The number of cycles of loading of a specified type that a specified material can withstand before failure.
Fatigue
Condition of material under stress that has lost, to some degree, its power of resistance as a result of repeated application of stress, particularly if stress reversals occur as with positive and negative cyclical loading.
Fast Track
Method that telescopes or overlaps traditional design-construction process. Overlapping phases as opposed to sequential phases is keynote of the concept.
Facing brick
The brick used and exposed on the outside of a wall. Usually these have a finished texture.
Fatigue Test
A test to determine the behavior of a material under fluctuating stresses.
Fan Coil Unit
The fan and heat exchanger for cooling and heating that are assembled in a common cabinet.
Fatigue Strength
A measure of the ability of a material or structural member to carry a load without failure when the loading is applied a specified number of times.
Factor of Safety
Ratio of the ultimate unit stress to the working or allowable stress.
