32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Net assignable area
- The usable floor area of a space measured to the inside faces of enclosing walls, excluding circulation, columns, and mechanical shafts.
- Efficiency ratio
- Net assignable area divided by gross area, expressing how much of a building supports its primary function; office targets are often 0.75 to 0.85.
- Adjacency matrix
- A planning tool that lists spaces in rows and columns and rates the required proximity of each pair to guide block planning and bubble diagrams.
- Bubble diagram
- A non-scaled diagram using circles or shapes to represent spaces and lines to show functional relationships, used early in programming and schematic design.
- Occupant load
- The number of people a space is designed to hold, calculated from floor area divided by the occupant load factor in IBC Table 1004.5.
- Universal design
- Design of environments usable by all people to the greatest extent possible without adaptation, guided by seven principles including equitable use and flexibility.
- IBC occupancy groups
- Classification of buildings by use, such as A assembly, B business, E educational, F factory, H high hazard, I institutional, M mercantile, R residential, S storage, and U utility.
- Type I construction
- The most fire-resistive construction type under the IBC, using noncombustible materials with high hourly fire-resistance ratings for structural elements.
- Means of egress
- A continuous and unobstructed path from any point in a building to a public way, consisting of exit access, exit, and exit discharge components.
- Accessible route
- A continuous, unobstructed path connecting accessible elements and spaces, with a minimum clear width of 36 inches and compliant turning spaces.
- Floor area ratio
- The total building floor area divided by the lot area, used in zoning to regulate building bulk and density on a site.
- MasterFormat
- A CSI standard organizing construction specifications into 50 divisions by work type, with Division 01 for general requirements and Division 09 for finishes.
- Performance specification
- A specification that states required results or performance criteria rather than prescribing specific materials or methods, allowing contractor flexibility.
- Water-cement ratio
- The ratio of water to cementitious material in a concrete mix, controlling strength, durability, and workability; lower ratios generally increase strength.
- Nominal vs actual lumber
- Nominal dimensions are the rough sawn size before surfacing; actual dimensions are smaller, such as a 2x4 measuring 1-1/2 by 3-1/2 inches.
- Rainscreen principle
- An exterior wall design that separates cladding from the drainage plane with an air space, allowing moisture to drain and evaporate.
- Submittal review
- The architect's review of contractor shop drawings, product data, and samples for design intent; it does not approve means and methods or shift responsibility.
- Footcandle
- A unit of illuminance equal to one lumen per square foot; one footcandle equals 10.76 lux, used to specify lighting levels.
- Luminous efficacy
- The efficiency of a light source measured in lumens per watt; LEDs typically exceed 100 lm/W while incandescent lamps are about 15 lm/W.
- Color rendering index
- A scale from 0 to 100 describing how accurately a light source renders colors compared to a reference; values above 80 are generally acceptable for interiors.
- Sensible heat ratio
- The sensible cooling load divided by the total cooling load, indicating how much of the load is temperature versus moisture removal.
- Fixture units
- A numerical value assigned to plumbing fixtures based on their load-producing effect, used to size water supply and drainage piping.
- Equal friction method
- A duct sizing technique that selects duct dimensions to maintain a constant pressure drop per unit length along the duct run.
- Drawing scale
- The ratio of drawing size to actual size, such as 1/4 inch = 1 foot for architectural plans or 1:100 for metric drawings.
- Orthographic projection
- A method of representing three-dimensional objects in two dimensions using plan, elevation, and section views projected onto planes.
- Construction documents
- The drawings and specifications that define the scope, materials, and workmanship of a project and form part of the contract for construction.
- Level of Development
- A BIM framework from LOD 100 to LOD 500 describing the degree of detail and reliability of model elements at each project phase.
- Door schedule
- A tabular drawing component listing each door's mark, size, type, material, hardware, and fire rating, forming part of the contract documents.
- AIA B101
- A standard owner-architect agreement defining basic services, compensation, and responsibilities for design and construction contract administration.
- Design-bid-build
- A project delivery method where the owner contracts separately with an architect for design and then with a contractor selected through competitive bidding.
- Standard of care
- The degree of skill and care ordinarily exercised by architects under similar circumstances; it is the benchmark for professional negligence claims.
- Substantial completion
- The stage when the work is sufficiently complete for the owner's intended use, triggering warranty periods and final payment procedures.
