BiH Engineering & Architecture Licensure Exam common mistakes
BiH Engineering & Architecture Licensure Exam · Understand the traps and how to avoid them.
Answering ethics items from personal workplace habit rather than from the statutory duties of the licensed engineer, e.g. treating a conflict-of-interest disclosure as optional courtesy.
Candidates generalize from private practice norms and never anchor answers in the legal duties of the profession, so plausible-sounding but non-compliant options feel correct.
What to do instead
Before the exam, write a one-page summary of the engineer's statutory duties (competence limits, disclosure, signing and stamping only own work, confidentiality, advertising limits) and, for each practice question, ask which stated duty is triggered before reading the options.
Confusing the roles of the design engineer, the supervising engineer, and the contractor's site engineer when a question describes a site dispute or a change order.
The same person often performs several roles in small Bosnian firms, so candidates map their own multi-role experience onto questions that test formally separated responsibilities.
What to do instead
Build a table of who may issue instructions, who certifies payment, who approves material substitutions, and who bears liability for defects, then classify every practice-scenario question by role before choosing an answer.
Choosing a structural member size or reinforcement from remembered rules of thumb instead of carrying out the check the question actually requires.
Time pressure and habit push candidates toward pattern recognition; many also skip the governing load combination or the second-order/instability check.
What to do instead
Practice a fixed sequence for every structural item: identify limit state, list load combinations, compute internal forces, check capacity and serviceability, then verify detailing minima; do at least 30 timed drills where the sequence is written out.
Treating seismic action as a static lateral force only, ignoring ductility class, regularity, and capacity design requirements.
Candidates memorize base-shear formulas but not the conceptual rules that govern behavior factors, irregularity penalties, and detailing for dissipation.
What to do instead
Study one worked example per structural system (frame, wall, dual) tracing how ductility class changes the behavior factor, the detailing, and the allowed analysis method; be able to state why each change occurs.
Selecting a foundation type from the building height alone without checking bearing capacity, settlement, or groundwater conditions.
Candidates jump to 'deep foundations for tall buildings' and skip the geotechnical evidence the question supplies, such as SPT values, plasticity, or a high water table.
What to do instead
For every foundation question, list the given soil parameters first, compute or bound bearing capacity and settlement, compare against allowable limits, and only then choose shallow versus deep; practice reading borehole logs quickly.
Assuming a material property from its name or supplier claim rather than from the specified test standard, curing, and acceptance criteria.
Candidates memorize typical strength values but not how sampling frequency, curing regime, and conformity rules change whether a batch is accepted.
What to do instead
Create a one-page matrix of material, test standard, specimen, curing condition, acceptance criterion, and sampling frequency for concrete, steel, masonry, and asphalt, and rehearse it until recall is automatic.
Mixing up steady-state U-value calculation with dynamic or summer overheating assessment, or omitting thermal bridging when computing envelope performance.
Candidates learn U-values in isolation and never connect them to condensation risk, thermal bridging, and the energy performance certificate logic.
What to do instead
Work through one full envelope example end to end: layer-by-layer resistance, U-value with and without bridge penalties, surface temperature and condensation check, then annual energy implication; repeat for a roof and a floor.
Answering planning questions with generic good-urbanism principles instead of the specific plan hierarchy, permitted parameters, and procedure required by law.
Candidates rely on design intuition and do not memorize which plan level governs which decision or which approval step is mandatory.
What to do instead
Draw the plan hierarchy (state, regional, municipal, detailed) with the instrument, the competent authority, and the public participation step at each level, and answer planning items by locating the decision in that chart.
Confusing the critical path with the longest-duration activity, or misreading float when a schedule question includes resource constraints.
Candidates compute forward and backward passes mechanically without checking what float means for delaying the project completion date.
What to do instead
Practice ten network diagrams by hand, stating for each activity its early and late dates, total and free float, and the effect of a two-week delay; verify that the critical path has zero total float.
Ignoring escape route geometry, compartmentation, or fire-resistance ratings when answering fire safety items, focusing only on extinguisher placement.
Candidates conflate active and passive measures and do not link occupancy class to travel distance, exit width, and structural fire resistance.
What to do instead
Build a checklist linking occupancy type to travel distance, number and width of exits, compartment size, and required fire resistance, and apply it to every fire item before reading the options.
Treating environmental protection as a separate topic from construction sequencing, so answers miss erosion control, waste management, and noise limits embedded in the works procedure.
Candidates study environmental rules as a list of permits and fail to see them as constraints on method statements and site layout.
What to do instead
For one typical building and one road project, write the method statement with environmental hold points inserted (topsoil stripping, sediment control, waste segregation, working hours), then answer environmental items by reference to those hold points.
Skipping the unit check and the order-of-magnitude sanity check on numerical answers.
Under time pressure candidates accept the first number that matches a distractor computed with a common slip such as kN versus kNm or millimetres versus metres.
What to do instead
Adopt a mandatory final step: state the unit of the answer, estimate the expected magnitude, and reject any option off by a factor of ten before marking; drill this on 20 mixed numerical items.
