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 building excluding circulation, walls, and mechanical spaces; used to calculate space needs and efficiency ratio.
- Adjacency matrix
- A grid that shows required relationships between spaces, rating each pair as direct, close, neutral, or undesirable; guides bubble diagrams.
- Occupant load factor
- The floor area per person used to calculate occupant load; for business use typically 100 gross square feet per person under model codes.
- STC rating
- Sound Transmission Class: a single-number rating of how well a partition blocks airborne sound; higher values mean better privacy.
- NRC rating
- Noise Reduction Coefficient: a rating of how much sound a surface absorbs; values range from 0 (reflective) to 1 (fully absorptive).
- Punch list
- A list of minor incomplete or defective work items identified during substantial completion; contractor must correct before final payment.
- Change order
- A written modification to the construction contract that changes scope, cost, or schedule; requires owner approval and architect's evaluation.
- RFI
- Request for Information: a formal contractor question seeking clarification of contract documents; architect responds in writing within a specified time.
- Submittal
- Shop drawings, product data, or samples submitted by the contractor for architect review to verify compliance with design intent and specifications.
- Performance specification
- A specification that states required results or performance criteria rather than specific products or methods; contractor chooses means to meet criteria.
- Life-cycle cost
- Total cost of a building element over its life, including initial cost, operation, maintenance, and replacement; used to compare design alternatives.
- Egress width
- The required width of exit access, exits, and stairs based on occupant load and capacity factors; minimum 36 inches clear for accessible routes.
- Travel distance
- The maximum distance from any point in a space to an exit, measured along the path of travel; limits vary by occupancy and sprinkler protection.
- Accessible route
- A continuous unobstructed path connecting accessible elements and spaces; minimum 36 inches wide, with turning spaces and proper slopes.
- Bubble diagram
- A schematic drawing using circles or bubbles to represent spaces and lines to show required adjacencies; used in early space planning.
- Block plan
- A scaled diagram showing approximate sizes and shapes of spaces and their relationships; more detailed than a bubble diagram.
- LPD
- Lighting Power Density: the maximum allowed lighting wattage per square foot under energy codes such as ASHRAE 90.1; office values around 0.9 W/sq ft.
- Color temperature
- A measure of light source warmth or coolness in kelvin; 2700–3000 K is warm, 3500–4000 K neutral, 5000–6500 K cool.
- Daylight factor
- The ratio of indoor illuminance at a point to outdoor illuminance under overcast sky; expressed as a percentage; 2–5% target for offices.
- Sound masking
- A system that adds low-level background noise to reduce speech intelligibility and improve acoustic privacy in open offices.
- FF&E
- Furniture, Fixtures, and Equipment: movable items not part of base building construction; specified in Divisions 11 and 12.
- Ergonomic workstation
- A workstation designed to fit the user: keyboard height 26–28 inches, monitor top at eye level, adjustable chair with lumbar support.
- Casework
- Built-in cabinetry and millwork such as base cabinets, wall cabinets, and countertops; specified with materials, finishes, and hardware.
- Mockup
- A full-size physical sample of a construction assembly or finish used to verify workmanship, appearance, and performance before full installation.
- Fire-resistance rating
- The duration in hours that a building element resists fire exposure; required ratings depend on construction type and occupancy.
- Flame spread
- A rating of how quickly a material propagates flame; interior finish codes limit flame spread and smoke developed index.
- GMP contract
- Guaranteed Maximum Price: a contract where the contractor agrees not to exceed a set price, sharing savings or covering overruns per terms.
- Substantial completion
- The stage when the work is sufficiently complete for the owner to use it for its intended purpose; starts warranty periods and punch list.
- Critical path method
- A scheduling technique that identifies the longest sequence of dependent tasks; delays on the critical path delay the project completion.
- Low-VOC materials
- Products with low emissions of volatile organic compounds, such as paints, adhesives, and carpets; improve indoor air quality and meet green standards.
- NC rating
- Noise Criteria: a single-number rating of background noise level; lower values are quieter; offices typically NC 25–35.
- Efficiency factor
- The ratio of net assignable square feet to gross square feet; indicates how much of a building is usable; typically 0.65–0.80 for offices.
