  12. Elevations - The page on the blue prints that depicts the house or room as if a vertical plane were passed through the structure. Normally it includes at minimum the front, rear, and two sides of the building, properly scaled. A bouns would be elevations of specific rooms or details in the house.
  13. Energy Calculation Form
  14. Engineered Floor Systems
  15. Expansion Joint - A device used to permit a structure to expand or contract without breakage. In residential construction, a bituminous fiber strip used to separate blocks or units of concrete to prevent cracking due to expansion as a result of temperature changes. Also used on concrete slabs.

  17. Flitch Plate
  18. Flood Zone
  19. Floor Plan - The basic layout of building or addition, which includes placement of walls, windows and doors as well as dimensions.
  20. Floor Trusses

Timely filing is essential to support the encumbrance, and prescribed filing dates vary by jurisdiction.
  30. Mixed Bearing Walls
  31. Mortar Types - Type M is suitable for general use and is recommended specifically for masonry below grade and in contact with earth, such as foundations, retaining walls and walks. Type M is the strongest type. Type S is suitable for general use and is recommended where high resistance to lateral forces is required. Type N is suitable for general use in exposed masonry above grade and is recommended specifically for exterior walls subject to severe exposures. Type O is recommended for load-bearing walls of solid units where the compressive stresses do not exceed 100 lbs. per square inch and the masonry wall not be subjected to freezing and thawing in the presence of excessive moisture.
  32. NOA
  33. Non Load Bearing Walls
  34. Payment Schedule - A pre-agreed upon schedule of payments to a contractor usually based upon the amount of work completed. Such a schedule may include a deposit prior to the start of work.

  41. Roof Pitch - The incline slope of a roof or the ratio of the total rise to the total width of a house, i.e., an 8-foot rise and 24-foot width is a one-third pitch roof. Roof slope is expressed in the inches of rise per foot of run.
  42. Scratch Coat: The first coat of stucco, which is scratched to form a bond for the second coat.
  43. Screed or Screeding - The wood or metal straightedge used to strike off or level newly placed concrete when doing cement work. Screeds can be the leveling device used or the form work used to level or establish the level of the concrete. Screeds can be hand used or mechanical.
