Grade-2 Registered Architect (China) common mistakes
Grade-2 Registered Architect (China) · Understand the traps and how to avoid them.
In the drawing exam (建筑构造与详图作图), candidates draw the detail from memory without first checking the required scale and dimensioning conventions, so the drawing is technically correct in concept but fails on line weights, missing dimensions, or wrong scale.
Under time pressure, candidates rush to start drawing and skip the instruction page. They also rely on textbook details rather than adapting to the specific project conditions given in the prompt.
What to do instead
Spend the first 5–8 minutes reading all requirements and listing mandatory elements (scale, line types, dimension chains, annotations). Set up layers and line weights before drawing. After finishing, do a checklist pass: every material layer labeled, every dimension closed, every symbol per current 制图标准.
In building design (建筑设计), candidates produce a plan that meets the brief's room list but violates fire compartmentation, egress distance, or accessibility requirements, losing major points.
Candidates focus on functional zoning and aesthetics and treat code compliance as a separate afterthought. They often misremember the exact thresholds for travel distance, stair width, or door clearances.
What to do instead
Before sketching, extract every quantitative code trigger from the brief (occupancy, area, height, egress). Create a one-page compliance checklist and check the plan against it at 30-minute intervals. Memorize the most common thresholds (e.g., 袋形走道 limits, 疏散楼梯最小宽度, 无障碍坡道坡度) through weekly flashcards.
In structural selection (建筑结构与结构选型), candidates choose a structural system based on architectural preference without verifying span-to-depth ratios, lateral stiffness, or material suitability, resulting in an uneconomical or unsafe scheme.
Candidates often lack field experience with real span limits and rely on rules of thumb from textbooks that are outdated or oversimplified. They also ignore the interaction between structural grid and architectural module.
What to do instead
Build a personal table of typical economic spans and depths for common systems (frame, shear wall, truss, cable, shell). For each design problem, first calculate the required span and load, then shortlist two systems and compare. Practice past exam questions on structural selection with a focus on justification, not just the final answer.
In building construction detailing (建筑构造与详图), candidates draw a detail without resolving the sequence of layers and the waterproofing/thermal bridging continuity, producing a detail that leaks or fails energy code.
Candidates memorize details as pictures rather than understanding the functional requirements (rain screen, vapor barrier, insulation continuity). They also neglect the specific climate zone and material properties given in the prompt.
What to do instead
For each detail type (roof, wall, foundation, window), write a one-paragraph functional narrative: what must stop water, air, vapor, and heat, and in what order. Then draw the detail and check that each control layer is continuous and correctly positioned. Practice with real product data sheets to understand thicknesses and jointing.
In building physics and services (建筑物理与建筑设备), candidates guess values for U-values, daylight factors, or equipment sizes instead of calculating from first principles, leading to wrong answers on quantitative questions.
Candidates rely on memorized typical values without understanding the underlying formulas. They also confuse units (W/m²K vs. m²K/W) and mix up steady-state and dynamic metrics.
What to do instead
Re-derive the core formulas (thermal resistance, heat loss, daylight factor, duct sizing) from the exam syllabus and practice with unit tracking. Create a formula sheet with units and typical ranges, and solve at least 20 numerical problems per topic. For services, learn to read schematic diagrams and trace flow paths.
In building materials and construction (建筑材料与构造), candidates select materials based on generic reputation (e.g., 'concrete is strong') without considering the specific exposure conditions, compatibility, or construction sequence required by the question.
Candidates study materials in isolation and do not connect them to detailing and site practice. They also overlook the difference between material properties (strength, durability) and construction requirements (curing, jointing).
What to do instead
For each material family, create a matrix of key properties, typical applications, and common failure modes. When answering, explicitly state the exposure condition and justify the choice against at least two alternatives. Practice detailing joints between dissimilar materials and specifying construction sequence.
In professional practice (法律、法规、经济与施工), candidates answer legal and contractual questions based on intuition rather than the exact wording of the relevant regulation or standard contract, and they mismanage time on the calculation-heavy cost questions.
The legal and economic content is text-heavy and candidates avoid deep reading. They also underestimate the time needed for quantity/cost calculations and rush, making arithmetic errors.
What to do instead
Study the primary laws (建筑法, 招标投标法, 合同法) and standard contracts article by article, highlighting numbers and deadlines. For cost questions, practice with a structured calculation template and always double-check units and percentages. Allocate time per question type in mock exams and stick to it.
Across all domains, candidates fail to manage the total exam time, spending too long on one drawing or calculation and leaving entire sections blank, which guarantees failure regardless of knowledge.
Candidates practice content but not exam pacing. They also lack a strategy for when to abandon a difficult question and move on.
What to do instead
Take at least three full-length timed mock exams under realistic conditions. Before each, set a time budget per section (e.g., 1.5 minutes per multiple-choice question, 3 hours for the drawing). During practice, enforce a hard stop and mark incomplete items for review. Learn to recognize when a question is a time sink and skip it.
In the drawing exam, candidates ignore the provided grid or existing conditions and design a detail that cannot be built because it lacks space for insulation, structure, or construction tolerance.
Candidates treat the drawing as a freehand sketch and do not scale elements properly. They also forget that real construction requires tolerances, access for tools, and sequence.
What to do instead
Always draw to scale using the provided grid. Before finalizing, check that every layer has a realistic thickness and that there is room to install and finish. Add a note on construction sequence where relevant. Practice by redrawing standard details from manufacturer manuals at the same scale as the exam.
In building design, candidates neglect site context and climate, producing a scheme that ignores orientation, prevailing winds, or site access, and thus fails the site planning criteria.
Candidates focus on the building itself and treat the site as a blank canvas. They also underestimate the weight of site planning in the scoring.
What to do instead
Start every design question by analyzing the site: orientation, access, noise, views, and climate. Sketch a site diagram before building massing. Explicitly address solar orientation and natural ventilation in the design concept. Practice with past site plans and have them reviewed against a checklist of site planning criteria.
