From Sketchbook to Spec Book
Architect interview questions probe your ability to hold two minds at once: concept and constructability. You are expected to design boldly, then document carefully enough that the building survives the real world.
Interviewers look for fluency in BIM and also in constraints: zoning envelopes, egress math, envelope performance, and coordination with MEP and structure. They are also listening for your client skill, how you protect intent while respecting budget and schedule.
This guide focuses on the questions that separate a drafter from a project leader: design phases, code thinking, Revit standards, detailing decisions, and how you respond when the field says your detail cannot be built.
Design Phases & Process
Q: Walk me through the standard AIA design phases and the primary deliverable for each.
The architectural process is structured into five phases. Schematic Design (SD) focuses on the “Big Idea.” Deliverables include rough floor plans, site analysis, and massing models to establish the look and scale. Design Development (DD) refines the concept. We select materials, fix dimensions, and coordinate with structural/MEP engineers. The deliverable is a set of drawings where the building is fully defined but not yet detailed for construction.
Construction Documents (CD) is the heavy lifting. We produce the technical specifications and detailed drawings required for bidding and permitting. Bidding & Negotiation (BN) involves answering contractor questions and selecting the builder. Finally, Construction Administration (CA) is the observation phase, where we review submittals and RFIs to ensure the building is built per the design intent.
Q: How do you approach a Zoning Analysis for a new site?
Zoning dictates what is legally possible before we draw a single line. I start by identifying the jurisdiction and the specific zoning district (e.g., Commercial C-2). I analyze the FAR (Floor Area Ratio) to determine the maximum allowable buildable area. I check Setbacks (front, side, rear yards) which define the buildable envelope.
I also investigate Height Limits (often tied to street width or bulk plane), Lot Coverage percentages, and Parking Requirements. Ignoring zoning early on leads to redesigns later. I summarize these constraints in a “Zoning Memo” or massing diagram to set the boundaries for the design team.
Q: Explain the concept of “Universal Design” vs. ADA Compliance.
ADA Compliance is meeting the legal minimum standards of the Americans with Disabilities Act (e.g., 1:12 ramp slopes, 36-inch door widths, 60-inch turning circles). It is a code requirement that prevents discrimination. Universal Design is a philosophy that goes beyond the code. It aims to create environments usable by everyone without the need for adaptation.
For example, an ADA entry might have a separate ramp next to stairs. A Universal Design entry grades the entire site so the main path is step-free for everyone (strollers, wheelchairs, delivery carts). I strive for Universal Design because it integrates accessibility invisibly and elegantly, rather than treating it as a “handicap add-on.”
Q: How do you calculate Egress Width for a commercial building?
Safety is the architect’s primary license obligation. To calculate egress, I first determine the Occupant Load using IBC Table 1004 (e.g., Business Use = 100 gross sf per person). If I have a 10,000 sf office, that’s 100 occupants.
Next, I apply the width factor (IBC Section 1005). For stairways, it is typically 0.3 inches per occupant. For other components (doors/corridors), it is 0.2 inches per occupant. So, 100 people need 30 inches of stair width and 20 inches of door width. However, I must also respect the minimum code widths (e.g., 44 inches for commercial stairs, 32 inches clear for doors). The larger of the calculated width or the minimum width governs the design.
Revit Proficiency & Technical Detailing
Q: Revit Families: System vs. Component
System Families are hard-coded into Revit (Walls, Floors, Roofs, Ceilings, Stairs). You cannot save them as external RFA files; you can only transfer them between projects using “Transfer Project Standards.” Component (Loadable) Families are external RFA files (Doors, Windows, Furniture, Beams) that you create in the Family Editor and load into the project. Understanding this distinction is vital for template management and library organization.
Q: Fire Partition vs. Fire Barrier
A Fire Partition (usually 1-hour rated) typically separates tenant spaces or dwelling units. It can stop at the rated ceiling assembly (it doesn’t need to go to the deck) if the ceiling is rated. A Fire Barrier offers higher protection (1, 2, 3, or 4 hours) and is used for vertical exit enclosures (stairwells) or separating different occupancies. Crucially, a Fire Barrier must extend continuously from the floor slab to the underside of the floor/roof deck above, sealing all penetrations.
Q: Managing Revit Worksets
Worksets are the mechanism for work-sharing in a Central Model. I organize Worksets not just by user, but by building system (e.g., “Shell,” “Interiors,” “Furniture,” “Linked Models”). This allows users to “close” heavy worksets (like Furniture) to improve model performance. I also ensure the “Shared Levels and Grids” workset is locked/checked out by the BIM Manager to prevent accidental movement of the building’s coordinate system.
Q: Building Envelope: Vapor Barriers
The rule of thumb is “don’t trap moisture.” The location of the vapor barrier/retarder depends on the climate. In cold climates (heating dominated), the vapor barrier goes on the warm side (interior) of the insulation to stop indoor humidity from condensing in the wall cavity. In hot/humid climates (cooling dominated), it goes on the exterior. Getting this wrong leads to mold and structural rot inside the wall assembly.
Q: LOD (Level of Development) 300 vs 400
LOD defines the reliability of the BIM element. LOD 300 is typical for Construction Documents: the element is modeled with specific quantity, size, shape, location, and orientation. It is suitable for bidding. LOD 400 adds fabrication and assembly information (e.g., rebar detailing, connection bolts, duct flanges). Architects rarely model to LOD 400; that is the realm of the subcontractor’s shop drawings. We stop at LOD 300 or 350 (coordination).
Q: Coordinating with MEP Consultants
Coordination prevents “Clashes.” I don’t just overlay their link; I cut sections. The biggest conflicts occur in the ceiling plenum. I need to verify that the gravity drain lines (which must slope) don’t hit the structural beams or the light fixtures. I use “Copy/Monitor” in Revit for grids and levels to ensure we are physically aligned. Regular clash detection meetings using Navisworks are essential during the DD and CD phases.
Project Scenarios & Problem Solving
The client insists on a design feature that violates the building code. How do you handle this?
I cannot compromise on life safety or code compliance; my license depends on it. However, I never just say “No.” I explain the “Why” behind the code (e.g., “That dead-end corridor limit exists so people don’t get trapped during a fire”).
Then, I pivot to a solution. I try to find an alternative way to achieve their aesthetic or functional goal within the legal constraints. For example, “We can’t have a door there due to travel distance, but we could use a fire-rated glass partition to keep the visual transparency you want.” If they persist, I must formally document the code violation and refuse to sign/seal that specific detail, escalating to firm principals if necessary.
During the CA phase, the contractor submits an RFI stating your window detail is unbuildable. What do you do?
First, I check my ego. If I drew it wrong, I own it. I review the detail against the field conditions. Often, “unbuildable” just means “difficult” or “expensive,” or perhaps the sequencing is wrong (e.g., the waterproofing needs to go in before the frame).
I would call the Superintendent to discuss. “What specifically is the clash?” I ask for their proposed solution (they often have a good idea). If their solution maintains the aesthetic intent and weather-tightness integrity, I issue a sketch to approve it. If not, I sketch a workable detail that respects the field constraints. The goal is to keep the project moving, not to defend a drawing.
The project is over budget, and the client demands Value Engineering (VE). How do you protect the design integrity?
VE often turns into “Cost Cutting” where design quality suffers. To protect the design, I categorize the building elements. I identify the “Sacred” elements (the lobby feature wall, the main facade) that define the project’s identity. I fight to keep these.
I then offer up the “Invisible” elements for VE. Can we switch from custom cabinets to semi-custom in the back-of-house? Can we simplify the lighting control system? Can we change the flooring in secondary corridors? I proactively present a menu of savings that I can live with, preventing the client or contractor from indiscriminately slashing the budget in areas that ruin the user experience.
Advanced Practice & Sustainability
Q: How do you integrate LEED or Sustainability strategies early in the design?
Sustainability cannot be an afterthought applied during CDs. I start with Passive Design in the SD phase. I orient the building massing to maximize daylighting while minimizing solar heat gain (e.g., elongating the East-West axis). I study the wind rose for natural ventilation.
For LEED certification, I create a “Scorecard” in the kick-off meeting to target specific credits (Location, Water Efficiency, Energy). I ensure the spec writer includes low-VOC requirements and that the contractor knows about construction waste management goals. Integrated design means the mechanical engineer and I discuss envelope performance (R-values) before the walls are drawn.
Q: Describe the difference between a “Specified” product and a “Performance” spec.
A Proprietary/Descriptive Spec names a specific manufacturer and model (e.g., “Sherwin Williams Paint Color X”). This guarantees the exact look but reduces competitive bidding. A Performance Spec describes the required result (e.g., “Roofing membrane must withstand 120 mph wind uplift and have a 20-year warranty”). This allows contractors to find the most cost-effective solution that meets the criteria. I use Proprietary specs for aesthetic finishes and Performance specs for hidden systems like concrete or waterproofing.
Q: What is a “Wall Section” and why is it the most critical drawing?
The Wall Section cuts vertically through the building envelope. It is the Rosetta Stone of the set. It shows how the structure, the waterproofing, the insulation, and the finish materials interact. It defines the vertical dimensions (floor-to-floor, window heads, parapet heights).
More importantly, it is where we trace the “Four Barriers”: Water, Air, Vapor, and Thermal. If I can’t trace a continuous line for each barrier up the wall section, the building will leak or fail. It is the primary tool for coordinating with the structural engineer.
Q: How do you handle “Scope Creep” from a client during the CD phase?
Scope creep kills profitability. If a client adds a new room or changes a layout during CDs, I must pause. I reference the contract and the signed-off DD package. I inform the Project Manager immediately.
We then issue an “Additional Service Request” (ASR) to the client, outlining the extra fee and schedule impact required to make the change. I explain, “We can definitely make that change, but it will delay the permit submission by two weeks and cost $X in redesign fees.” Often, seeing the price tag makes the client reconsider if the change is truly necessary.

❓ FAQ
✏️ In an interview, what matters more: portfolio or technical answers?
Both, but they prove different things. Your portfolio shows taste and intent. Your technical answers show you can deliver a building, coordinate consultants, and avoid basic code and detailing failures.
📚 How deep does building code knowledge need to be?
You should be comfortable with core life-safety concepts: occupancy, egress, fire ratings, accessibility, and common triggers. You do not need to cite every section number, but you must explain decisions clearly.
🖥️ What Revit skills do firms actually care about?
Clean modeling habits, template discipline, worksharing basics, and coordination workflows. A beautiful model that crashes or cannot be documented is not a win.
🧩 How do you handle VE without destroying the design?
Protect the intent by ranking priorities. Keep the moves that drive experience, and simplify the parts that do not. Bring options with pros and cons, and show how cost changes without compromising performance.
🧑💼 How do you push back when a client wants something that breaks code?
Explain the “why” behind the rule, then offer alternatives that preserve their goal. If they insist on a violation, document it and escalate. Your license cannot be a negotiation.
