Every successful construction project is built on a foundation of smart financial decisions. One of the biggest sources of stress for homeowners and developers is the fear of surprise costs and budget overruns. This is precisely why a structured design process is so critical. It’s a system designed to catch potential issues and refine the scope before they become expensive problems on the job site. By understanding the different architectural project phases, you can see how your budget is allocated and protected at each stage. This guide will walk you through the process, showing you how early planning and detailed documentation ultimately save you money and prevent costly changes down the road.
Introduction
Architectural design is an intricate and detailed process, with careful consideration of the project’s context, budget, goals, materials, and regulations. From conception to completion, there are multiple phases that must be followed to ensure success. In this article, we will explore each of these phases in greater detail; from initial concept to the completion of construction, we will look at the major milestones, key considerations, and common mistakes to avoid. We will also provide you with best practices for adapting these phases to meet specific project needs and give you an idea of how the architectural fees can be broken down across all the phases. With this comprehensive guide, you’ll have all the information you need to ensure your project is a success from start to finish.
The “pre design phase”
Problem-Seeking: Defining Your Project’s “Why”
Think of the pre-design phase as the foundation for your entire project. Before any lines are drawn or materials are chosen, it’s essential to understand the core purpose of the build. This initial step, often called “problem-seeking,” is all about defining your “why.” It’s a collaborative process where we sit down with you to discuss your vision, needs, and goals. Are you looking to create more functional space for a growing family, design a commercial property that reflects your brand, or build your dream home from the ground up? Answering these questions helps establish the overall scope and ensures the final design is a true reflection of your objectives, preventing costly changes down the road.
Pre-Design Timeline and Deliverables
Once we understand your goals, we move into the technical details. This involves a thorough analysis of your property, including its existing conditions, and a deep dive into local zoning laws and building codes that will influence the design. For example, an Accessory Dwelling Unit (ADU) has specific regulations that must be addressed from the very beginning. The key deliverables from this phase serve as the project’s roadmap. You’ll typically receive a “Program,” which outlines all the required spaces and their approximate sizes, a “Zoning Summary” detailing applicable regulations, and initial drawings of the existing site. Investing time here is crucial; it’s far easier and more cost-effective to adjust a plan on paper than it is to move a wall once construction has started.
BENEFITS OF EARLY ENGAGEMENT
There are significant benefits to engaging with your architect in the pre-design phase. Their experience and knowledge can assist in a better understanding of your project scope. By having an initial consultation meeting your architect, they can advise on what administration and regulations may be applicable, whether the project is feasible, and what other design experts will be needed prior to you undertaking the design process. They will also be able to strategize the flow of information between the project team and ensure efficient consulting with the various design experts. Usually discussions and input during pre-design will serve as additional design services, and is specifically recommended for high complexity projects or for first time clients to help navigate them through all the design phases. work in an existing building may also require early engagement as this can often have significant hidden challenges which an experienced architect will have knowledge of. At level the following services make up the Pre-design phase of a typical project.
- Site analysis,
- programming,
- existing conditions,
- budgeting,
- code review

Architectural design phases
As a client embarking on a construction project, it is important to understand the different architectural design phases set out by the American Institute of Architects (AIA) and the key considerations for each of the five phases. The design process, from the schematic design, to the completion of construction, can be complex and multi-faceted, but with a solid understanding of the architectural design process, you can ensure a successful outcome. In this article, we will provide an in-depth exploration of the AIA’s architectural design phases, including major milestones, common mistakes to avoid, and best practices for successful execution. https://www.aia.org/resources/6246433-guides-for-equitable-practice
Phase 1: Schematic Design Phase:
The first phase of the architectural design process is the schematic design phase, accounting for approximately 15% of the architectural fee breakdown. During the first phase, your architect will work with you to establish the project scope, program requirements, and the overall schematic design of the construction project. They will also conduct an analysis of the job site and create basic design sketches and layouts. This phase sets the foundation for the remaining five phases, so it is important to have clear communication with your architect and a shared understanding of your vision for the project leading into the design development.
OUTCOMES OF THE sCHEMATIC DESIGN PHASE
The Schematic design phase is where the size, shape and basic layout of the building are determined. This phase usually requires significant client input for the architect to begin preparing drawings and communicate the basic design by means of models and rough sketches. Good communication between client and architect will result in a clear understanding of the design intent and offer a good overview of the entire construction project. At this stage the architect may want to consult with other design experts such as structural, mechanical and wet-service engineers, depending on the complexity of the schematic design and relevant architectural data.
Schematic Design Timeline
So, how long does schematic design take? Generally, you can expect this phase to last anywhere from a few weeks to a couple of months. The exact timeline really hinges on your project’s complexity and how quickly decisions can be made. This is a highly collaborative period where you’ll work closely with your architect to define the project’s goals and overall vision. They’ll translate your ideas into preliminary drawings, like floor plans and basic exterior sketches. You should anticipate a healthy amount of back-and-forth as you provide feedback on these initial concepts. For more intricate designs, your architect will also bring in other experts, such as a structural engineer, to confirm the design is viable from the start. Your clear communication and active involvement are the most important factors in keeping this phase moving forward efficiently.
Phase 2: Design Development Phase:
The next phase is the design development phase and accounts for approximately 20% of the architectural fees. Here you and your architect will work together to refine the outcome of the schematic design phase into a more detailed final design. This will include selecting materials, specifying finishes and products such as doors, windows, fixtures and any built in appliances. This phase is concluded when both client and architect have clearly established the interior and exterior design and have progressed well in refining the technical specifications, project specific systems and building systems which will be detailed in the construction documents phase. The architect will also co-ordinate the design with various other consultants at this stage for their input.
Coordinating the design with the various design experts
In order for any architectural project to be a success it is critical that the design is coordinated between all the various design experts and specialist trades making up the project team. The best way to ensure success on your project is to communicate the design development to the structural, mechanical, electrical, plumbing and any other applicable experts as early on in the design process as possible. The architect plays a central role in this coordination as they often have the best overall understanding of the design intent and a basic working knowledge of how the various components of the building need to fit together.
Communicating the design development.
It’s important to keep in mind that during this phase, changes can still be made, but they will become more difficult and costly as the project progresses. At Level, the architectural design team compile design development construction documents including building elevations, plans and 3D renderings to clearly communicate the design to the client. Design development drawings ensure that the final design aligns with the outcomes established in the pre-design and schematic design phases. Once the design is agreed, these documents will be approved by all parties in order to proceed to the next phase.
COST ESTIMATE DURING DESIGN DEVELOPMENT phase
An important outcome of the design development stage is to provide preliminary cost estimates. These will be rough estimates that will be reviewed under the next phase, leading up to the bidding process. The design will be reviewed throughout this stage for compliance with local and national building codes and regulations.
Design Development Timeline
The design development phase can take anywhere from a few weeks to a couple of months, depending on your project’s complexity and how quickly decisions are made. This is where your project really starts to take shape. We’ll build on the initial sketches from the schematic phase, refining the layout and working through the specifics. You’ll be selecting materials, finishes, and fixtures—like windows, doors, and appliances. At the same time, our architectural design team coordinates with structural and mechanical engineers to ensure every detail is integrated properly. The goal is to finalize the design and produce a detailed set of drawings, which allows us to create a more accurate preliminary cost estimate before moving on to the final construction documents.
Phase 3: Construction Documents Phase:
The construction documents phase makes up the largest portion of the architect’s work, owing to around 40% of the architectural fees. The architect prepares multiple sets of construction drawings, including a set to be submitted to the local building and planning department, showing compliance with planning laws and bylaws and building regulations. Another set of detailed construction drawings, schedules of quantities and specifications will be produced to be used for bidding by construction contractors and construction. Each of these sets contain key information to ensure smooth and satisfactory completion of your project.
CONSTRUCTION Documents
For a typical project these documents include, but are not limited to the following:
- Floor plans
- Elevations
- Sections
- Architectural details
- Technical Details
- Door and Window schedules
- Finishing schedules
ENSURING ACCURACY AND COHESION
The complete set of construction drawings can be extensive and will include drawings from the various consultants and design experts appointed for their design services. One of the biggest challenges faced during the Construction Document phase is to ensure that there are no clashes between the various components and services that make up the entire project. The architect plays an instrumental role in coordinating the detailed drawings of all the design experts and all the project specific systems, prior to commencing the bidding process. The coordination and communication between the experts is best managed by the architect as this ensures a single cohesive set of construction documents to be sent to the construction company for an accurate bid.
COST ESTIMATES DURING THE PHASES OF ARCHITECTURAL DESIGN
Architecture firms are often able to provide preliminary cost estimates that run alongside design development, providing the client with a rough cost estimate to ensure the project stays within broad budgetary constraints. For more complex projects it is better advised to have a dedicated cost estimator or quantity surveyor on board throughout the architectural design process to ensure the design intent can be carried through to construction.
Construction Documents Timeline
Given that this phase is the most detailed and collaborative part of the design process, it naturally takes the longest to complete. The timeline can range from several weeks for a straightforward remodel to a few months for a complex new home build. The duration depends heavily on the project’s scale and the level of coordination required between different experts. During this stage, your architect is meticulously creating detailed drawings while also integrating plans from structural, mechanical, and electrical engineers. This back-and-forth is essential to ensure every component works together seamlessly, preventing costly surprises and delays once construction begins. Patience during this phase is key, as the thoroughness of these documents directly impacts the smoothness of the bidding and building stages that follow.
Phase 4: Building Permitting
This phase is all about getting the official go-ahead from your local building department. Once the construction documents are complete, they are submitted to the city or county for review. This step is non-negotiable; you can’t legally start building without an approved permit. The primary goal is to ensure your project is safe and complies with all local zoning ordinances and building codes. While it might seem like a bureaucratic hurdle, it’s a crucial checkpoint that protects you, your future occupants, and the community. This phase typically accounts for about 5% of the total architectural fee and involves a lot of administrative work, which is why having an experienced team to manage the submission and communication with city officials is so valuable.
The Permitting Process and Timeline
The timeline for securing a building permit can be one of the most unpredictable parts of a project. After submitting the plans, a city plan reviewer meticulously checks every detail against a long list of regulations. The duration depends heavily on the complexity of your project and the workload of the local building department. A simple interior remodel might get approved in a few weeks, while a new home build could take several months. It’s common for the reviewer to return the plans with comments or requests for clarification. Addressing these comments promptly and accurately is key to keeping the process moving. A thorough and well-coordinated set of construction documents is your best tool for a smooth review, as it minimizes the back-and-forth and demonstrates a clear understanding of the requirements for all architectural services involved.
Phase 4: Bidding and Contractor Selection
The construction documents are used to solicit bids or negotiate a contract with a contractor in the bidding or negotiation phase. This phase makes up 5% of the architectural fees, and can be run as a competitive bidding process or a negotiation with a contractor directly appointed by the client. If the client has a direct contractor that they prefer, it can be useful to include them in the discussions during earlier phases of the architectural design process. This will speed up the negotiations and ensure they have a clear understanding of the entire project.
competitive bid packages
It is important to note that no architect or cost estimator cannot guarantee the price of construction according to their estimates. In order to have a guaranteed price of construction, the project must be costed by a general contractor under the bidding phase.
SUBMITTING BID packages
The most effective way to ensure a fair and reasonable costing is to undertake a competitive bid process where multiple contractors submit bids based on identical construction documents and project information making up the competitive bid package.
- IFB (Letter explaining what is being bid for, the format required and the timeline for bids to be submitted
- Full set of construction drawings
- Schedules of quantities and specifications
- Timeline for the project
- Initial estimates (If cost estimator was involved)
- Preambles or any special conditions/contract conditions to be adhered to in the bidding.
REVIEWING THE BID and selecting a contractor
You and your architect will review the bids in order to select a contractor. Diligence during this process is crucial in ensuring that the project is built within budget and on schedule, and that you have a good understanding of the costs and timelines of the project. Care should be taken in reviewing the bids as the cheapest option or lowest bid is not always the correct choice. Taking the most expensive bid is also not always advised and the only way to make an informed decision is to compare each line item across all Bidding contractors to establish the best construction company for your specific project. Once the contractor is appointed the architect will issue a construction set of drawings to build from.
Understanding Costs, Fees, and Estimates
Let’s talk about money, because no project moves forward without a clear budget. During the design development phase, your architect will provide preliminary cost estimates. Think of these as a financial check-in to ensure the design is staying within your target budget. It’s important to remember these are educated guesses, not guarantees. The real numbers come later from contractors. The bulk of your architectural fees, often around 40%, goes toward the construction documents phase. This is because your architect is creating highly detailed drawings and specifications that every trade will use to build your project accurately. For more complex projects, bringing a dedicated cost estimator on board early can provide an extra layer of financial clarity and help keep the design aligned with your budget from the start.
The Impact of Change Orders
Changing your mind is easy, but in construction, it comes with a price tag. Any modification made after the construction documents are finalized is called a “change order,” and it can affect both your budget and your timeline. A small tweak during the design phase is a simple fix on a computer screen. That same tweak after walls have been framed and drywall is up can mean costly demolition and rework. The best way to avoid this is to be thorough and decisive during the design development phase. This is also why early coordination with all the experts is so critical. When your architectural team works hand-in-hand with structural and mechanical engineers from the beginning, potential conflicts are resolved on paper, saving you from expensive surprises down the road.
Bidding and Negotiation Timeline
Once your construction documents are complete, it’s time to find out exactly what your project will cost to build. This is the bidding phase, where you solicit proposals from general contractors. The most effective way to get a fair and competitive price is to have several contractors bid on the exact same set of documents. This ensures you’re comparing apples to apples. While your architect’s earlier estimates gave you a ballpark figure, the bids from contractors are the real deal—they represent a guaranteed price for construction. Carefully reviewing these bids with your architect is key. The lowest bid isn’t always the best choice; you want to select a reputable contractor who understands the scope of your remodel or addition and can deliver quality work.
Phase 5: Construction Administration phase:
The construction administration phase makes up the final 20% of the architectural fees. Your architect’s role is to provide construction oversight and ensure that the contractor is building the project according to the construction documents and to address any issues that arise during construction. This phase is critical in ensuring that the project is built as designed, and that any issues are resolved in a timely manner. The advantages of the architect having coordinated all the inputs of the various design experts will surface during this phase as most of the issues would have been addressed across the first four phases of design. They will have a detailed knowledge of the construction program and where the applicable trades fit in. This will help avoid abortive work and potential delays or cost overruns. Majority of the architect’s work in this phase will consist of inspections of the job site and meetings with the contractor and other design experts. This ensures the quality of execution and that the work is carried out in line with the conditions of the building permit and design development construction documents. The architect may also be required to review contractor’s monthly invoices and issue payment certificates which ensure that the amounts being invoiced align with progress on site. Once the final payment certificate is issued and final payment is made, the construction phase is concluded along with the project as a whole.
The Architect’s Role: Oversight vs. Supervision
During construction, it’s helpful to understand your architect’s specific role. They aren’t there to supervise the contractor’s team day-to-day; that’s the general contractor’s job. Instead, your architect provides construction oversight. This means they act as your eyes and ears on the job site, making periodic visits to ensure the project is being built according to the construction documents you approved. They attend meetings with the contractor and other experts to address any issues that pop up, ensuring the quality of work aligns with the design intent. This phase is where all the meticulous planning pays off, as a well-coordinated set of documents from an experienced architecture team minimizes surprises and keeps the project on track.
Developing the Final Punch List
As construction winds down, you’ll move to one of the final steps: creating the punch list. Think of this as the project’s final to-do list. Your architect will walk through the site with you and the contractor to identify any items that need to be corrected or completed before the project is officially finished. This could include anything from a paint touch-up to a missing fixture or a door that doesn’t close properly. This list is documented and given to the contractor to complete. Once all the items on the punch list are resolved to your satisfaction, the architect can issue the final certificate for payment, officially concluding the construction phase.
Your Architect as Your Advocate
Throughout every phase, but especially during construction, your architect is your primary advocate. They have the most comprehensive understanding of the project’s design and how all the different components—from the foundation to the roofline—are meant to work together. If a contractor suggests a change or an unexpected issue arises, your architect is the one who can advise you on the best path forward, protecting both your vision and your budget. They review the contractor’s invoices to make sure you’re being billed correctly for the work completed. Having this expert in your corner ensures the final result is exactly what you dreamed of, without you having to become an expert in construction yourself.
Closeout:
The final phase of the process is the closeout, where your architect ensures that the project is completed according to the contract documents and that all necessary closeout documents are provided. This phase is essential in ensuring that the project is completed to your satisfaction and that all necessary documentation is in order. Once all documentation is in place and any snags are attended to, the project will reach final completion.
Your Role: How to Be a Great Client
While your architect and their team of experts handle the technical details, your role as the client is absolutely vital to the project’s success. Think of yourself as the project’s visionary and key decision-maker. Being a great client doesn’t mean you need to know everything about construction; it means being engaged, communicative, and decisive throughout the process. Your clear input and timely feedback are the foundation upon which a successful design is built. By understanding your responsibilities during each phase, you can help keep the project on track, within budget, and true to your original vision, ensuring the final result is exactly what you dreamed of.
During Pre-Design and Schematic Design
This initial stage is all about exploration and setting the foundation for your entire project. Your primary role here is to communicate your vision, needs, and priorities as clearly as possible. Come prepared to discuss your lifestyle, how you plan to use the space, your aesthetic preferences, and your budget. The more information you share, the better your architect can translate your ideas into a tangible concept. It’s also crucial to be open and responsive during this phase. Your architect will present initial sketches and floor plans, and your timely feedback is essential. This collaborative process is a core part of any successful architectural service and helps refine the design before it becomes too detailed and costly to change.
During Design Development and Construction Documents
As the project moves into these more technical phases, your role shifts from broad-strokes visioning to making specific, concrete decisions. Your architect will present you with options for materials, finishes, fixtures, and appliances. Making these choices in a timely manner is critical to keeping the project moving forward and preventing delays. This is also when other experts, like a foundation engineer, are brought in to coordinate their designs. Your consistent vision helps ensure all the pieces fit together seamlessly. Before the final construction documents are completed, take the time to review everything carefully. This is your last chance to catch details that don’t align with your expectations before they are submitted for permits and sent out to builders.
Adapting the phases of architectural design
The architectural design process can be adapted to meet the specific needs of your project. This is especially applicable with projects such as existing buildings or buildings that have unique design challenges, or require specialized expertise to develop highly complex systems. Your architect will consult with specialists and experts regarding other project specific systems and adapt the phases of design to suit the inputs they require. This may include structural specialists for unique structural solutions or mechanical engineers, where a large amount of mechanical or electrical services may be required and could result in additional construction administration. Even items such as exterior and interior finishes that require specific provisions to be made earlier on in the construction program can result in a different design process. It is the architects role to ensure all these matters are communicated timeously and that all the various experts and specialists are aware of what is required of them.
Best Practice for Successful Execution:
The phases of design are set out in order to simplify the sometimes overly complex process of architectural design. Architecture firms such as Level Engineering, are dedicated to providing their clients excellent architectural services across all the phases ensuring a finished project that surpasses client expectations. The best practice to ensure successful completion for your project, is to appoint the right experts to guide you along the way.
Actionable Recommendations for a Smooth Project
Navigating an architectural project can feel like a huge undertaking, but you have more control over the process than you might think. Being an engaged and informed client is one of the best ways to ensure your project stays on track, on budget, and true to your vision. The relationship with your design team is a partnership, and clear communication is the foundation of that partnership. By taking a few key steps, you can help your architect and engineers deliver the best possible outcome while making the entire experience much smoother for everyone involved. Here are a few practical recommendations to keep in mind as you move through the design phases.
Provide Feedback Early
Your voice is most powerful in the early stages of design. During the Schematic Design phase, ideas are fluid and changes are relatively easy and inexpensive to make. This is the time to speak up, ask questions, and share your thoughts openly. Don’t worry about not knowing the technical jargon; a good architect will be able to translate your vision into a workable plan. As one architecture firm puts it, “Don’t be afraid to say if you don’t understand something.” If a layout feels awkward or a concept doesn’t quite match what you pictured, say so. Providing clear, honest feedback early on prevents costly and time-consuming revisions later in the process, ensuring the final design truly reflects your goals.
Hire Licensed Professionals
This might seem obvious, but it’s a crucial step that protects your investment. Always ensure you hire architects and engineers who are licensed and insured in your state. A license is more than a piece of paper; it’s proof that the professional has met rigorous standards for education, experience, and examination. It ensures they are knowledgeable about local building codes, safety regulations, and permitting processes. Working with a firm like Level Engineering, which has licensed architects and structural engineers on staff, provides an extra layer of assurance. It confirms that every aspect of your project, from the initial design to the structural integrity, is handled by qualified experts committed to professional and ethical standards.
Appreciate the Value of Detailed Documents
The Construction Documents phase produces the most detailed and technical drawings of the entire process, and their importance cannot be overstated. Think of these documents as the comprehensive instruction manual for your builder. As we note on our architecture service page, “One of the biggest challenges faced during the Construction Document phase is to ensure that there are no clashes between the various components and services that make up the entire project.” A thorough and well-coordinated set of documents prevents confusion, reduces the risk of errors during construction, and allows for more accurate bidding from contractors. While they may seem complex, these detailed plans are what transform a design concept into a buildable reality, saving you from costly surprises and delays down the road.
Frequently Asked Questions
Why is the pre-design phase so important? It seems like a lot of talk before any real design happens. Think of the pre-design phase as creating a detailed map before starting a road trip. It’s where we define exactly what you want to achieve and confirm it’s feasible before a single line is drawn. This early investment of time prevents expensive backtracking later. By sorting out your goals, budget, and any site constraints from the start, we ensure the entire project is built on a solid foundation, which saves you from costly detours once construction is underway.
What is the single most important thing I can do to keep my project on budget? The best way to protect your budget is to be as decisive as possible during the design phases. Changes made on paper are simple and inexpensive to adjust. However, once construction begins, any modification is called a “change order,” which can lead to delays and significant extra costs for labor and materials. Finalizing your decisions before the builders arrive is the most effective way to prevent budget surprises.
Why do the construction documents take so long to create? The construction documents are the comprehensive instruction manual that tells the builders exactly how to construct your project. This phase is intensive because your architect is coordinating every single detail, from the structural plans created by engineers to the electrical layout and plumbing lines. This meticulous work ensures all the different systems fit together perfectly, which prevents costly errors and confusion on the job site. A thorough set of documents is the key to a smooth build.
What’s the difference between my architect’s cost estimate and a contractor’s final bid? An architect’s cost estimate, which is provided during the design process, is an educated projection to help guide decisions and keep the design aligned with your budget. A contractor’s bid, on the other hand, is a firm price for the actual construction. We use the detailed construction documents to get competitive bids from multiple contractors, which gives you a guaranteed cost and helps you choose the right builder for your project.
My architect is involved during construction, but are they managing the builders every day? During the construction phase, your architect acts as your advocate and provides oversight, not daily supervision. They will visit the site periodically to ensure the work aligns with the approved plans and quality standards. The general contractor is responsible for managing the construction crew day-to-day. Your architect is there to answer questions, solve problems that arise, and make sure your vision is being executed correctly.
Key Takeaways
- Embrace the Process to Protect Your Budget: The architectural phases are designed to catch potential issues early. Making decisions and changes on paper during the pre-design and schematic stages is far less expensive than altering plans once construction is underway.
- Your Feedback is Most Powerful in the Beginning: Be vocal and decisive during the initial design phases. Your clear input on layouts and concepts helps the architect create a plan that truly fits your needs, preventing costly revisions down the line.
- Detailed Documents are the Blueprint for Success: The comprehensive plans created during the Construction Documents phase are the most critical tool for your builder. Their accuracy and thoroughness ensure you get accurate bids from contractors and minimize errors and delays on the job site.
