32 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Reflected ceiling plan
- A drawing showing the ceiling as viewed from above and projected down, so it mirrors the floor plan and aligns grid lines, columns, and partitions with the plan below.
- Scale ratio equivalents
- Common drawing scales expressed as ratios: 1/8 inch equals 1 foot is 1:96; 1/4 inch equals 1 foot is 1:48; 1/2 inch equals 1 foot is 1:24.
- Line weight hierarchy
- Heaviest lines mark elements cut by the section plane and solid poché; medium lines show surfaces beyond the cut; the lightest lines carry dimensions, notes, and reference grids.
- Room finish schedule
- A table listing each room against its floor, base, wall, and ceiling finish codes, keyed to a legend that specifies products, colors, and installation standards.
- Revision cloud and delta
- A scalloped cloud surrounds changed drawing content, and the adjacent numbered triangle refers to a revision block entry giving the date, description, and authorizing document.
- MasterFormat Division 09
- The MasterFormat division covering finishes, including gypsum board, tiling, acoustical ceilings, flooring, wall coverings, and paints and coatings.
- Three-part specification section
- Standard format in which Part 1 General covers references, submittals, and quality assurance; Part 2 Products covers materials and components; Part 3 Execution covers installation and field quality control.
- Type X gypsum board
- A gypsum panel with a specially formulated core that improves fire resistance, usually 5/8 inch thick and used in rated wall and ceiling assemblies tested to ASTM E119.
- Performance specification
- A specification stating the required end result, such as a fire rating or acoustic rating, while leaving selection of materials and installation methods to the contractor.
- ASTM F2170 moisture test
- An in-situ relative humidity probe test measuring moisture deep within a concrete slab before moisture-sensitive flooring or coatings are installed, compared against the manufacturer's limit.
- Sound transmission class
- An ASTM E90 single-number rating of how well a partition blocks airborne sound; higher values mean greater privacy, and STC 50 is generally good for offices.
- ASHRAE 62.1
- The standard establishing minimum ventilation rates and indoor air quality procedures for commercial buildings, expressed as cubic feet per minute per person plus per square foot by occupancy.
- Lighting power density
- Installed lighting power per unit of floor area in watts per square foot, capped by space type under ASHRAE 90.1 and the IECC, calculated separately for interior and exterior.
- Noise criteria rating
- A single-number rating of background noise from mechanical systems; roughly NC 25 to 30 suits private offices and conference rooms, while NC 35 to 40 suits open offices.
- Drainage pipe slope
- Horizontal drainage piping 2-1/2 inches and smaller slopes at 1/4 inch per foot, while piping 3 inches and larger may slope at 1/8 inch per foot.
- Volatile organic compound limits
- Low-emitting material criteria such as CDPH Standard Method Section 01350, GREENGUARD, or Green Seal cap emissions from adhesives, sealants, paints, and flooring.
- Business occupant load factor
- Group B business occupancy uses 100 gross square feet per occupant; occupant load equals the floor area divided by that factor, rounded up to the next whole person.
- Common path of egress
- The distance an occupant must travel before two independent egress routes exist; the code limits it to 75 feet, or 100 feet in sprinklered Group B occupancies.
- Ramp slope and landings
- Accessible ramps slope no steeper than 1:12, rise no more than 30 inches between landings, and provide 60-inch-long landings at the top, bottom, and turns.
- Accessible reach range
- Unobstructed high forward reach is 48 inches and low reach 15 inches above the floor; side reach over an obstruction up to 34 inches deep uses the same range.
- Dead-end corridor limit
- The code limits dead-end corridors to 20 feet, increased to 50 feet in sprinklered Group B occupancies where the code permits the longer dimension.
- Two means of egress
- At least two separate exits are required when the occupant load reaches 50 or more, and in other cases where common path or travel distance limits are exceeded.
- Net to gross ratio
- Net assignable area divided by gross building area; office planning commonly targets 75 to 85 percent efficiency, with the remainder going to circulation, cores, and mechanical space.
- Adjacency matrix
- A grid scoring the required proximity or separation between every pair of program spaces, used to generate bubble diagrams and block plans.
- Post-occupancy evaluation
- A structured assessment after move-in using surveys, observation, and measurement to determine whether the design met user and program needs.
- BOMA rentable area
- The BOMA measurement standard distinguishing rentable from usable area and applying a load factor that spreads shared spaces such as corridors and lobbies among tenants.
- Schematic design phase
- The early design phase establishing concept, program fit, and order-of-magnitude cost, typically representing a modest share of the architect's basic service effort.
- AIA A201 general conditions
- The standard document defining the rights, responsibilities, and procedures of owner, contractor, and architect, incorporated by reference into the construction contract.
- AIA G702 payment application
- The contractor's application and certificate for payment that the architect certifies, accompanied by G703 continuing the schedule of values and percent complete by line item.
- Substantial completion
- The stage when the work is sufficiently complete for the owner's intended use, starting warranties, permitting retainage reduction, and generating the punch list.
- Architect's standard of care
- The skill and diligence ordinarily exercised by design professionals performing similar services under similar conditions; it is a negligence standard, not a warranty of perfection.
- Architect's Supplemental Instructions
- A written clarification or minor change issued by the architect that does not alter contract sum or contract time; larger changes require a change order.
