Roles and Responsibilities of an Architect: 14 Key Duties

An architect is a licensed professional who designs buildings and guides them from the client's first brief to handover. In practice, the job comes down to five responsibilities:

1. Brief, budget and schedule: agreeing with the client what the building must do, what it may cost and when it is needed.

2. Design: shaping the building and its spaces, from the first options to a developed design.

3. Codes and permits: making sure the design meets the building code, zoning and accessibility rules, and obtaining the permits.

4. Drawings and specifications: producing the documents contractors price and build from.

5. Bidding and construction: helping the client choose a contractor, then administering the construction contract and visiting the site.

This guide explains what an architect is and what an architect does day to day, the architect's role in each project phase, the 14 key duties one by one, the difference between an architect, an engineer and an architectural designer, and how architects use AI today.

What Is an Architect?

Being an architect is both a job and a protected title. The job is to plan and design buildings and the spaces around them, balancing what the client needs with the site, the budget, safety and the rules, and often to guide the building through construction. The title has to be earned: in the US and the UK, only a licensed or registered professional may practise under it.

In the US there is no national license: each of the 55 jurisdictions (states and territories) licenses its own architects. As of October 2026, most require a degree from a NAAB-accredited program, all accept the Architectural Experience Program (AXP), which asks for 3,740 hours of documented experience, and all require the six-division Architect Registration Examination (ARE), according to NCARB. In the UK, the Architects Act 1997 lets only people on the register of the Architects Registration Board (ARB) practise under a name or title containing the word "architect"; naval, landscape and golf-course architects are the exceptions.

Architects also coordinate with engineers, contractors, and clients during each project stage. They prepare architectural drawings, guide design decisions, and verify that construction follows approved plans. In other words, an architect ensures that a concept becomes a practical and reliable structure. Their expertise supports performance, safety, and long-term building quality.

The role of an architect therefore needs technical knowledge, project management skills, professional judgment and a solid grasp of the rules a building must meet: building codes, zoning, fire safety and accessibility.

This guide focuses on what architects do. For the specialties they work in and what they earn, see our guide to the types of architects; the most in-demand architect skills, the architect certifications beyond the license and the famous architects who shaped the profession have guides of their own.

What Does an Architect Do?

An architect turns a client's needs into a design, turns the design into documents a contractor can price and build from, and often stays involved while the building goes up. According to the US Bureau of Labor Statistics (Occupational Outlook Handbook, last updated 27 August 2026), architects typically:

• Meet with clients to determine their objectives and requirements for a structure

• Give preliminary estimates of cost and construction time

• Prepare structure specifications

• Direct workers who prepare drawings and documents

• Prepare scaled drawings, with software or by hand

• Prepare contract documents for building contractors

• Manage construction contracts

• Visit worksites to make sure construction follows the plans

• Seek new work by marketing and giving presentations

The UK's National Careers Service describes the same job day to day: discussing ideas, materials, costs and timelines with clients, drafting plans by hand and with CAD, managing projects and visiting sites, making sure plans follow building law, safety regulations and budgets, and drawing up bids, contracts and planning applications.

Architect Job Description at a Glance

The Architect's Role in Each Project Phase

Most projects move through the same phases, although each country names them differently. In the US, the AIA's standard owner–architect agreement (B101-2017) defines five phases of basic services, from schematic design to construction; in the UK, the RIBA Plan of Work organizes a project into eight stages. The table lines them up:

The pairing of schematic design with RIBA Stage 2 comes from the RIBA's own comparison; the other rows are an approximate match, because the two systems split the work differently. The AIA's five phases are basic services: pre-design and post-construction work are agreed separately (AIA, Defining the architect's basic services).

14 Key Duties of an Architect

These 14 duties follow a project from the first meeting to handover. Not every architect takes on all of them for every project: the services depend on the agreement with the client.

1. Client consultation and the project brief

2. Site analysis and feasibility

3. Developing and presenting design options

4. Designing functional spaces

5. Creating drawings and models

6. Building codes, zoning and permits

7. Construction documents and specifications

8. Cost estimates

9. Keeping the design on budget and on schedule

10. Leading the design team and coordinating consultants

11. Bidding and contractor selection

12. Construction administration and site visits

13. Sustainability, continuing education and new tools

14. Project records, close-out and handover

Client Consultation and the Project Brief

Architects start each project with a structured consultation to understand functional needs, location constraints and user expectations. The result is the project brief, in the US often called the program: what the building must contain and how it will be used, what it may cost and when it is needed. This step sets the foundation for all technical and creative decisions.

During consultation and planning, architects typically:

• Identify core requirements and spatial expectations

• Evaluate current site conditions for accurate planning

• Outline the main project aims with the client

• Agree on a target budget and a first schedule

Site Analysis and Feasibility

Before the design takes shape, the architect checks what the site and the rules allow. Site analysis looks at the plot's size, shape, slope, orientation, access, views and any existing buildings; a feasibility study then tests whether the brief fits the site, the planning rules and the budget. In the RIBA Plan of Work 2020 this work belongs to Stage 1, Preparation and Briefing; in the US, the AIA treats site evaluation and feasibility as a service separate from the five basic design phases.

Key tasks include:

• Visiting the site and gathering surveys of the land and any existing buildings

• Checking zoning and planning rules, such as permitted uses, heights and setbacks

• Testing whether the brief fits the site and the budget

• Setting milestones for the design stages

Developing and Presenting Design Options

Once the brief and the site are clear, the architect develops design options and presents them so the client can choose a direction. In the AIA's schematic design phase this usually means a site plan, floor plans, sections, an elevation and illustrative material such as renderings or models, with a first cost estimate. Presenting is also how architects win work: the BLS lists marketing and giving presentations among their typical tasks.

This phase normally includes:

• Creating concept ideas that match user needs

• Preparing sketches, renderings and models the client can understand

• Structuring cost ranges and project phases

• Presenting the options through drawings, images and short summaries

Many architects now test early directions as images before they model them in detail. With ArchiVinci's AI render generator you upload a sketch, a massing view or a screenshot of a model view (JPG, PNG or WebP up to 5 MB), describe materials and light in a sentence, and get a photorealistic image that follows your upload in seconds. Each run draws a new image, so you can show the client several directions side by side. A new account starts with 3 free credits; using the images for client work needs an active plan.

Designing Functional Spaces

Functional space design focuses on how people use each area within the building. Architects balance layout efficiency with comfort and safety. For example, circulation routes must remain clear while lighting and proportions support each room's purpose. Our guide to space planning covers the clearances and steps at room scale.

This step often involves:

• Studying user behavior and operational needs

• Testing alternative layouts for better performance

• Positioning rooms for accessibility and comfort

• Integrating structural and mechanical requirements

To compare layouts before the design is fixed, you can sketch them in Floor Plan Maker, ArchiVinci's floor plan tool for desktop browsers: draw walls and rooms, which show their areas, or let it generate a furnished layout from a short brief (property type, total area, floors, bedrooms and bathrooms), then check each option in 3D and walk through it. You can ask for another variation at any time, and generation from a brief runs without AI and costs nothing.

Creating Drawings and Models

Architectural drawings translate ideas into precise graphical information: they define dimensions, materials and spatial relationships, so engineers and builders can understand the full technical scope. As the design develops, the architect keeps the set up to date, adding measurements, coordinating details with the structural and mechanical engineers, building digital models for visualization and revising drawings when the client's needs change. The BLS notes that architects prepare scaled drawings either with software or by hand.

Typical outputs include:

• Floor plans and elevations

• Sections that explain vertical relationships

• Site plans that place the building on its plot

• Details that illustrate construction methods

For floor plans, Floor Plan Maker can also rebuild an uploaded plan image, PDF or hand sketch as an editable 2D plan with walls, doors, windows and room areas; AI plan reading costs 1 credit on a free account and is refunded if the conversion fails. You can add dimension lines and several floors, work in metric or imperial units, and export DXF for CAD (it can be saved as DWG there), PDF, SVG or PNG. It does not draw sections, elevations or site plans: those stay in your CAD or BIM software.

Building Codes, Zoning and Permits

Every design has to meet the rules that apply where it will be built: the building code, zoning and planning rules, fire safety and accessibility requirements. The architect checks the design against them as it develops, prepares the drawings and documents that the planning application and the building permit need, and answers the questions of the officials who review them.

This work usually includes:

• Checking the design against the building code, zoning, fire safety and accessibility rules

• Preparing drawings and documents for planning applications and building permits

• Answering the questions of planning and building officials

• Updating the design when an approval sets conditions

Construction Documents and Specifications

Construction documents turn the approved design into detailed drawings and specifications that set out what must be built and to what standard. In the AIA's sequence they come after design development, and the contractors' final estimates are based on them. The BLS lists preparing structure specifications and contract documents for building contractors among an architect's typical tasks.

Core components are:

• Detailed construction drawings with dimensions, sections and details

• Specifications describing materials, products and workmanship

• Schedules listing doors, windows, finishes and components

• Contract documents that set out each party's obligations

Cost Estimates

Architects give clients preliminary estimates of cost and construction time, as the BLS puts it, and refine them as the design develops. In schematic design, the AIA describes costs estimated from the project's overall volume; the detailed figures come later, when contractors price the construction documents. An architect's estimate is therefore a planning tool, not a final price.

Cost estimating includes:

• Estimating early costs from the building's size and type

• Updating the estimate as the design and specifications develop

• Suggesting design or material changes when the estimate exceeds the budget

• Presenting estimates for client approval

Keeping the Design on Budget and on Schedule

Maintaining budgets and timelines supports overall project stability. Architects monitor progress and identify issues before they cause delays. In the meantime, they coordinate with consultants to keep design revisions under control.

This responsibility involves:

• Tracking updated costs and schedules

• Reviewing drawings for potential conflicts

• Preparing adjustments when scope changes

• Reporting progress for client review

Leading the Design Team and Coordinating Consultants

Architects lead the design team and coordinate the work of the other consultants. The BLS lists directing the workers who prepare drawings and documents among their typical tasks, and in the AIA's design development phase the architect coordinates the structural, mechanical, electrical and plumbing design with the architecture. Good coordination catches conflicts between disciplines on paper, before they reach the site.

Team management includes:

• Assigning tasks to design members

• Reviewing consultant work for consistency

• Organizing workshops for coordination

• Confirming that technical goals are met

Bidding and Contractor Selection

When the construction documents are ready, the project goes out to bid or is negotiated with one contractor. In the AIA's bid or negotiation phase, the owner evaluates the bids with the architect's help and selects a contractor. Comparing bids means looking beyond the price at what each one includes, the schedule and the contractor's experience.

Key activities are:

• Preparing the bid documents from the drawings and specifications

• Helping the owner compare bids and select a contractor

• Clarifying the documents for the contractor before work starts

• Preparing the documents for the construction contract

Construction Administration and Site Visits

During construction, the architect checks that the building follows the design, but the scope depends on the agreement. In the AIA's construction phase, the architect helps the contractor build the project as specified, answers questions from the site and administers the contract until the final payment certificate is issued; these services are at the owner's discretion. AIA Pennsylvania notes that some architects carry a project through construction, while others leave the oversight to the owner or the contractor. In the UK, the architect may act as contract administrator and inspect the works.

Typical tasks during construction include:

• Answering contractors' questions and clarifying details

• Attending site and coordination meetings

• Visiting the site at agreed milestones and recording observations

• Reviewing samples and mock-ups

• Checking completed work against the drawings and specifications

• Reviewing the contractor's payment applications

Sustainability, Continuing Education and New Tools

Architects monitor new technologies, materials, sustainability methods, and design research to strengthen design quality. These advancements help improve building performance by reducing energy use, enhancing comfort, and supporting long-term durability. As a result, each project gains a more informed and future-ready foundation.

Continuing education keeps that knowledge current; our guide to continuing professional development (CPD) explains how it works for architects. New digital tools are part of it, and the AI section below shows where AI fits into the duties of this guide and what it does not do.

Staying current includes:

• Studying material advancements

• Learning new digital design tools

• Evaluating global architectural case studies

• Applying updated methods in future work

Project Records, Close-out and Handover

At the end of a project, the architect organizes the drawings, specifications, approvals and reports into a record the client can use for maintenance and future renovations. In the AIA's sequence, construction-phase services end when the final payment certificate is issued; in the RIBA Plan of Work, Stage 6 is Handover and Stage 7 covers the building in use.

Documentation tasks include:

• Compiling all project drawings

• Organizing permit and approval forms

• Recording design changes for traceability

• Handing over the record drawings and project documents to the client

Architect vs. Engineer vs. Architectural Designer

Architects, engineers and architectural designers often work on the same building, but their jobs and licenses differ. The table draws on the BLS profiles of architects and civil engineers and on NCARB:

In short: the architect answers for the design as a whole, the engineer for the parts they design and sign off, and the contractor for building it.

How Architects Use AI Today

AI is now part of everyday practice. In the RIBA AI Report 2026, published in July 2026, the share of UK architecture practices using AI for most projects rose from 59% in 2025 to 74%. Of the respondents, 75% reported better productivity, but only 17% agreed that their designs are better because of AI, and 77% agreed that it can never replace human creativity.

Here is where AI tools fit into the duties of this guide:

For text work such as emails, briefs and reports, our guide to ChatGPT for architects covers uses, prompts and limits.

None of these tools checks a design against the building code, analyzes the structure or takes on the legal responsibility that comes with a license: ArchiVinci generates a new image that follows your upload and does not analyze a design, so an AI image is a design study, not a construction document, and every result needs the architect's review. A new account starts with 3 free credits, and commercial use of the images (client work, marketing) needs an active plan; plans are on the pricing page. For a wider comparison of AI-powered tools for visualization, see our list.

Architect Roles and Responsibilities: Frequently Asked Questions

What are the main services an architect provides?

There is no official list of "seven major architectural services". The AIA's standard agreement defines five phases of basic services: schematic design, design development, construction documents, bidding or negotiation, and construction. Counted with pre-design work (the brief, site evaluation and feasibility) and post-construction services, which are agreed separately, that makes seven groups of services, as in the phase table above.

Do you need a license to call yourself an architect?

In the US and the UK, yes. In the US, the title comes with a license from a state or territory; in NCARB's words, "Once you've earned a license, you can officially call yourself an architect." In the UK, the Architects Act 1997 lets only people on the ARB register practise under a name or title containing the word "architect", except naval, landscape and golf-course architects.

Does an architect supervise construction?

It depends on the agreement. In the AIA's standard phases, the architect administers the construction contract, visits the site and helps the contractor build the project as specified, but those services are at the owner's discretion, and some architects leave construction oversight to the owner or the contractor. The contractor builds the project; the architect checks the work against the design.

Do architects only work on large buildings or commercial projects?

No. Architects work on a wide range of projects, including homes, interior renovations, small additions, and adaptive reuse projects. Their skills apply to any scale that requires structured design and planning.

What software tools do architects commonly use today?

Most architects work in BIM and CAD software such as Revit, 3D modeling tools such as Rhino and real-time visualization tools such as Enscape, which runs inside Revit, SketchUp, Rhino, Archicad and Vectorworks (October 2026). Many also use AI-based design tools for specific tasks: ArchiVinci, for example, turns a sketch, a photo or a model view into a photorealistic image in seconds, and its Floor Plan Maker draws and converts floor plans in a desktop browser. These tools generate images and plans; they do not analyze a design. Our guides compare BIM software and explain real-time rendering.

Are architects involved in choosing building materials?

Yes. Architects guide material selection by evaluating durability, sustainability, cost, and performance. They collaborate with suppliers and engineers to confirm that chosen materials meet project requirements.

How do architects ensure a building is environmentally responsible?

Architects apply passive design strategies, energy modeling, and sustainable material choices. They also coordinate with environmental consultants to improve insulation, ventilation, and energy efficiency.

What is the difference between architectural drawings and construction drawings?

Both are architectural drawings; they differ in purpose and detail. Design drawings, made during schematic design and design development, show the layout, the appearance and how the spaces work, so the client can approve the design. Construction drawings are part of the construction documents: together with the specifications, they give the dimensions, materials, details and notes that contractors price and build from.

Do architects help clients understand project risks?

Yes. Architects identify potential risks related to costs, timelines, site conditions, and regulatory approvals. They offer strategies that help clients reduce uncertainty during both design and construction.

How early should clients involve an architect in a project?

The best results occur when architects are involved from the very beginning. Early involvement allows proper site evaluation, clearer planning, and more accurate budgeting, which overall strengthens project success.

Will AI replace architects?

Not entirely, according to the RIBA AI Report 2026: 77% of respondents agreed that AI can never replace human creativity, although 59% expect it to lead to staff reductions across the profession. AI tools speed up images, text and routine tasks, but the brief, the design decisions, code compliance and the legal responsibility stay with the architect. Our guide Will AI replace architects? looks at the question in depth.
