- Standard of Care
- The level of skill and diligence an ordinarily prudent, competent architect would exercise under similar circumstances. It is not a guarantee of perfection; AIA B101 expressly disclaims any warranty of services.
- Sole proprietorship
- A business owned by one person with no legal separation between owner and firm. It is simple to form but exposes the owner's personal assets to unlimited liability for the firm's debts and claims.
- Professional corporation (PC)
- An entity form many states require or allow for licensed professionals. It provides liability protection for ordinary business obligations while preserving professional-practice rules and licensee responsibility for negligence.
- Limited liability company (LLC)
- A flexible entity that shields owners' (members') personal assets from business debts while allowing pass-through taxation. Many states require a professional LLC (PLLC) form for architecture practice.
- S corporation
- A corporation that elects pass-through taxation, so income is taxed once at the shareholder level, avoiding the double taxation of a C corporation, while still providing a corporate liability shield.
- Net operating revenue
- Revenue the firm retains after deducting consultant fees and reimbursable expenses passed through to the client. It is the base for most firm financial ratios because it reflects money the firm keeps for labor, overhead, and profit.
- Overhead rate
- The ratio of indirect (non-billable) expenses to direct labor cost: overhead rate=direct laborindirect expenses. A rate of 1.5 means $1.50 of overhead per $1.00 of direct labor.
- Net multiplier
- Net operating revenue divided by direct labor — the revenue earned for each dollar of direct labor. It must exceed the break-even rate (1.0 plus the overhead rate) for the firm to profit.
- Break-even rate
- The multiplier needed to cover costs with no profit: 1.0+overhead rate. At a 1.5 overhead rate the break-even rate is 2.5; profit is added on top to set the net multiplier.
- Utilization rate
- The percentage of an employee's total hours that are directly billable to projects. Higher utilization improves profitability; it is a key measure when deciding whether the firm can afford a new hire.
- Professional liability (E&O) insurance
- Coverage protecting a firm against claims of negligence, errors, or omissions in professional services. It does not cover bodily injury or property damage (general liability) or express warranties the architect personally makes.
- General liability insurance
- Coverage for third-party bodily injury and property damage arising from the firm's operations. It does not cover claims of professional negligence, which require errors-and-omissions (E&O) coverage.
- Workers' compensation insurance
- State-mandated coverage for employees injured in the course of employment, providing medical and wage-replacement benefits. Most U.S. jurisdictions legally require employers to carry it.
- Betterment doctrine
- A liability principle that an owner should not receive a free upgrade when an architect's error is corrected. The architect's liability is limited to costs the owner would not otherwise have incurred had the work been designed correctly.
- Mediation
- A non-binding, facilitative dispute-resolution process in which a neutral mediator helps parties reach a voluntary settlement. AIA documents typically require it as a condition precedent because it is faster and cheaper than arbitration or litigation.
- Arbitration
- A private dispute-resolution process in which a neutral arbitrator hears evidence and renders a binding decision. It is generally faster and more confidential than litigation but, unlike mediation, produces an enforceable ruling.
- AIA Code of Ethics and Professional Conduct
- The AIA's framework of canons, ethical standards, and enforceable rules governing members' obligations to the public, clients, the profession, colleagues, and the environment, including honesty, confidentiality, and conflict-of-interest duties.
- Conflict of interest
- A situation in which an architect's obligations to one party are compromised by interests in another. The AIA Code requires architects to avoid conflicts or fully disclose them and obtain informed consent.
- Instruments of service
- The drawings, specifications, models, and other documents an architect prepares. Under B101 the architect is the author and owner of the copyright, granting the owner a limited license to use them for the project.
- Architectural Works Copyright Protection Act (AWCPA)
- A 1990 U.S. law extending copyright protection to the design of a building as embodied in built work, plans, or drawings, complementing the architect's copyright in the instruments of service.
- Stipulated-sum (lump-sum) contract
- A fixed-price agreement in which the contractor performs the work for an agreed amount, placing cost-overrun risk on the contractor. It shifts the most cost risk away from the owner compared with cost-plus arrangements.
- Cost-plus-fee contract
- An agreement reimbursing the contractor's actual costs plus a fee. It shifts more cost risk to the owner than a lump sum and is often paired with a guaranteed maximum price (GMP) to cap exposure.
- Practice-wide quality management program
- A firm-wide QA/QC system of standardized processes, checklists, and review milestones that delivers consistent quality and risk control across all projects, independent of which team performs the work.
- Public health, safety, and welfare
- The architect's paramount professional obligation. When a project request conflicts with this duty, the architect should decline or condition the engagement rather than proceed for fee considerations.
- Additional services
- Work beyond the agreed basic scope — such as redesigning previously approved work after an owner-directed change — for which the architect is entitled to additional compensation and, where appropriate, additional time under B101.
- Scope creep
- The gradual, uncompensated expansion of a project's services beyond the contracted scope. Defining included revisions and treating excess as additional services is the primary risk-management defense against it.
- Indemnification clause
- A contract provision in which one party agrees to compensate another for specified losses or claims. Architects negotiate to limit indemnity to losses caused by their own negligence to stay within insurable limits.
- Marketing and business development
- The firm-wide effort to identify prospects, build relationships, and win commissions through proposals, qualifications (e.g., SF330), and a clear value proposition, distinct from project-specific services.
- Direct vs. indirect labor
- Direct labor is time charged to specific billable projects; indirect labor is non-billable time (management, marketing, professional development). The split drives utilization and overhead calculations.

- Knowledge management
- A practice-wide system that captures standard details, lessons learned, and project documentation so institutional expertise is reused, improving efficiency, consistency, and risk reduction across projects.
- Risk management (firm level)
- The ongoing process of evaluating each potential project's risk profile — client, schedule, building type — and adjusting fee, scope clarity, schedule, and contract terms to mitigate the firm's exposure.
- Joint venture
- A temporary association of two or more firms formed to pursue a specific project, sharing resources, risk, and profit. It is distinct from a permanent partnership and ends when the project concludes.
- Design-bid-build
- A delivery method in which design documents are completed first, then a contractor is selected by competitive bid. The owner holds separate contracts with the architect (B101) and contractor (A101/A201).
- Design-build
- A delivery method in which a single entity holds both design and construction responsibility under one contract. Phases often overlap, so owner project requirements and design intent must be documented early and clearly.
- Construction manager as constructor (CMc / CM at-risk)
- A delivery method in which a construction manager joins during design to provide preconstruction services, then holds the trade contracts and typically guarantees a maximum price (GMP) for the work.
- Integrated project delivery (IPD)
- A collaborative delivery method binding owner, architect, and contractor under a multiparty agreement that shares risk and reward, aligning incentives and encouraging early collaboration and BIM use.

- The five core service phases under B101 — schematic design, design development, construction documents, bidding/negotiation, and construction administration — covered by the basic fee.
- Supplemental services
- Services the owner and architect identify and agree to include at the time of signing, listed in the B101 agreement, distinct from contingent additional services that are triggered later by circumstances.
- Contingent additional services
- Services triggered later by circumstances — such as revisions inconsistent with prior approvals or an owner-directed redesign — that entitle the architect to additional compensation when they arise.
- Customary phase fee distribution
- The typical split of the basic services fee: roughly SD 15%, DD 20%, CD 40%, Bidding/Negotiation 5%, and CA 20%. Construction documents carries the largest allocation.
- Critical Path Method (CPM)
- A scheduling technique that maps activities, durations, and dependencies to identify the longest path through the network. That path determines the minimum project duration.
- Critical path
- The longest continuous chain of activities through a CPM network, having zero total float. Any delay to a critical activity delays the entire project's completion.
- Total float (slack)
- The amount of time an activity can be delayed without delaying project completion: late start−early start. Critical-path activities have zero total float.
- Gantt chart
- A bar chart displaying project activities as horizontal bars along a calendar axis, making durations, start/finish dates, and overlaps easy to visualize. It is a scheduling and communication tool, not a contract.

- The official record of discussions, decisions, and action items from a project meeting, distributed to participants afterward. The agenda, by contrast, is prepared beforehand to set topics.
- Transmittal
- A cover document recording the formal transfer of items — drawings, specifications, samples — between parties, creating a dated record of what was sent and received.
- Project budgeting (fee allocation)
- Aligning staffing to each phase's fee: the project manager compares the fee earned in a phase against projected labor costs to keep the project profitable and adequately staffed.
- Consultant coordination
- The architect's responsibility under B101 for the services of the consultants it retains, including engaging qualified specialists via C401 and integrating their work into the design.
- Quality control (QC) review
- A structured internal review of documents at phase milestones that identifies errors, omissions, and inconsistencies before issuance, reducing claims and rework — a core risk-reduction practice.
- Constructability review
- A coordination review that cross-checks structural, mechanical, electrical, and architectural drawings to catch conflicts and confirm the design can be built before documents are issued for bidding.
- Resource management
- Assembling the project team and allocating staff, consultants, and time to match scope and budget, forecasting staff hours from the fee available in each phase.

- The governmental office or official responsible for enforcing code and approving permits. Discretionary AHJ approvals, like zoning variances requiring public hearings, introduce schedule uncertainty.
- Application for payment (architect's certification)
- The contractor's periodic request for payment based on work in place. Under A201 the architect reviews it and certifies only amounts properly due, and may withhold certification for cause.
- Schematic design (SD)
- The first design phase, establishing the project's general scope, scale, and relationships through study drawings. It carries roughly 15% of the basic services fee.
- Design development (DD)
- The phase that refines schematic design, fixing materials, systems, and dimensions. It carries roughly 20% of the basic services fee and prepares the project for construction documents.
- Project quality control objectives
- Maintaining code compliance, coordination/constructability, and design-objective integrity throughout delivery so the documents reduce risk and meet the owner's program.
- Communication plan
- An agreed protocol defining who communicates what, to whom, and through which documents (RFIs, minutes, transmittals), keeping the team coordinated and creating a defensible project record.
- Contract documents
- The set that legally defines the work: the owner-contractor agreement, general and supplementary conditions, drawings, specifications, addenda, and modifications, collectively binding the parties.
- Reimbursable expenses
- Project-related costs — travel, reproduction, permit fees — that the owner reimburses the architect at cost (often plus a markup), separate from the architect's compensation for services.
- Architectural programming
- The systematic process of defining a project's goals, required spaces, square footages, adjacencies, and performance criteria before design begins, producing the program that drives design decisions.

- Floor area ratio (FAR)
- A zoning limit on building bulk equal to permitted gross floor area divided by lot area. On a 20,000 ft2 lot, an FAR of 3.0 permits 60,000 ft2 of floor area.
- Setback
- The minimum required distance a building must be placed from a property line, established by zoning to control spacing, light, air, and access. Relief from a setback requires a variance.
- Zoning variance
- Discretionary relief from a dimensional zoning requirement (such as a setback) granted by the zoning board of appeals based on a unique hardship to the property, not from the building official.
- Special exception (conditional use)
- Authorization for a use the zoning ordinance already contemplates, allowed under stated conditions when criteria are met. Unlike a variance, it concerns use rather than dimensional relief.

- The contractor's assurance, typically one year under A201, that the work conforms to the contract documents and is free of defects, with the period generally beginning at substantial completion.
- Record drawings (as-builts)
- Drawings documenting the actual constructed conditions, including changes made during construction, assembled at closeout for the owner's future maintenance and modifications.
- Closeout documents
- The materials delivered at project completion — warranties, record drawings, operation and maintenance manuals, releases of liens, and final certifications — that conclude the contract.
- Post-occupancy evaluation (POE)
- A structured assessment of a completed building's performance in use, gathering feedback on how well it serves occupants and meets goals, informing operations and future projects.
- Preconstruction activities
- The architect's role in bidding or negotiation — assisting in evaluating bids, contractor selection criteria, and contract or design changes to adjust cost — before construction begins.
- Addendum
- A written change to the bidding documents issued before bids are received, modifying drawings or specifications. Addenda become part of the contract documents once incorporated.
- Bid evaluation
- The review of contractors' bids for completeness, responsiveness, and qualifications, with the architect assisting the owner in comparing proposals and recommending award.
- Mock-up
- A full-scale sample of an assembly or finish built for review and approval before mass production or installation, establishing the standard of quality the work must meet.
- Non-conforming work
- Work that does not meet the contract documents. The architect may reject it and require correction; under A201 the contractor is responsible for bringing it into conformance.
- Field report (observation report)
- The architect's written record of a site visit, noting observations of progress, conformance, and issues, documenting the construction-observation role for the project record.
- Initial decision maker (IDM)
- Under A201, the party (typically the architect) who renders an initial decision on claims between owner and contractor before mediation, a required step in dispute resolution.
- Liquidated damages
- A predetermined sum stated in the contract that the contractor owes the owner for each day of unexcused delay, compensating for losses that are difficult to calculate after the fact.
- Allowance
- A budgeted amount included in the contract sum for items not yet selected at bidding, reconciled by change order when the actual cost of the selected item is known.
- Unit price
- A pre-agreed price per measured quantity of work used to value additions or deletions when exact quantities are unknown at bidding, applied as the work proceeds.
- Product data submittal
- Manufacturer information — catalog cuts, performance data, installation instructions — the contractor submits to demonstrate a proposed product conforms with the specifications.
- Substitution request
- A contractor's proposal to use a product different from that specified, which the architect evaluates for equivalence in quality, performance, and design intent before approving or rejecting.
- Release of liens
- A document in which the contractor and subcontractors waive their right to file mechanic's liens, typically required with payment applications and at closeout to protect the owner's title.
- Project closeout
- The final phase concluding the contract: completing punch-list work, delivering warranties, record drawings, and O&M manuals, releasing retainage, and certifying final completion.
- Building performance evaluation
- Assessing how a completed building performs against design goals — energy, comfort, function — during operation, often via a POE, to verify outcomes and inform future work.
