Rzeczoznawca Budowlany (PIIB) common mistakes
Rzeczoznawca Budowlany (PIIB) · Understand the traps and how to avoid them.
Citing a Ustawa Prawo budowlane article number that has been renumbered or repealed since the last consolidated text, and building the answer on it without checking the current tekst jednolity.
Candidates memorize article numbers from old course notes or from a specific consolidated version, while the act is amended frequently and consolidated texts shift numbering; the exam expects the version in force on the date of the exam.
What to do instead
Before the exam, download the current tekst jednolity of Prawo budowlane from Dziennik Ustaw (isap.sejm.gov.pl) and mark the articles you rely on. In answers, cite the article number together with the substantive rule, so that even a numbering slip does not destroy the argument.
Treating 'pozwolenie na budowę' and 'zgłoszenie' as interchangeable, and failing to state which procedure applies to a given scope of works and which documents the inwestor must attach.
Candidates learn the general rule (pozwolenie) and the exceptions (zgłoszenie, brak wymogu) as a list, but do not practice matching a concrete described project to the correct procedure and to the required attachments.
What to do instead
Build a decision table: scope of works -> procedure -> required attachments -> authority -> deadlines. Work through 10-15 concrete project descriptions and classify each. Memorize the rule that a change of sposobu użytkowania and works listed in art. 29 ust. 1 pkt 1-3 have their own regime.
Describing the 'obszar oddziaływania obiektu' only by the plot boundary, without identifying the specific przepisy odrębne that define it and the actual extent of impact.
The definition in art. 3 pkt 20 is short, so candidates quote it and stop, missing that the extent must be derived from specific regulations (e.g. distances, shading, fire separation) and that the plot boundary is not decisive.
What to do instead
For each type of building, list the przepisy odrębne that set the impact (e.g. warunki techniczne distances, fire regulations, environmental rules) and practice deriving the boundary from them. In answers, state the definition, then name the regulations used to determine the extent.
Answering a 'zagospodarowanie działki' question with general urban-planning phrases while omitting the concrete parameters required: wskaźnik intensywności zabudowy, powierzchnia biologicznie czynna, linia zabudowy, miejsca postojowe.
Candidates read the MPZP or decyzja o warunkach zabudowy casually and then write about 'zgodność z planem' without the numbers, which the examiner treats as a lack of substantive analysis.
What to do instead
For every such question, extract and quote the actual parameters from the given plan or WZ decision, compare them with the proposed development, and show the calculation (e.g. PUM / powierzchnia działki). Always check the definition of powierzchnia biologicznie czynna in the rozporządzenie, not the colloquial meaning.
Mixing up the limit states in structural answers: checking only SGN (nośność) or only SGU (użytkowalność), and ignoring combinations, partial factors and the difference between characteristic and design values.
Candidates often learn formulas by heart but never practice the full design situation: combination of actions, partial factors, and the decision which limit state governs for the given element.
What to do instead
For each element type (beam, column, slab, foundation), write out the full check: actions -> combination -> SGN with design values -> SGU with characteristic values. State explicitly which limit state governs and why. Practice with one worked example per element type.
Describing a building installation (e.g. wentylacja, instalacja gazowa, odgromowa) only functionally, without citing the technical conditions it must meet and the required periodic inspections or odbiory.
Candidates from a construction-management background know installations in general terms but not the normative requirements (e.g. kubatura per person for ventilation, spadki for gas, resistance values for earthing) that the exam tests.
What to do instead
Create a one-page summary per installation: governing rozporządzenie/Polska Norma, key numerical parameters, required odbiory and periodic checks with their frequency, and who is authorized to perform them. Recite the numbers until they are automatic.
Presenting a property valuation with a final value but no documented approach, no justification of the chosen approach, and no reconciliation of results from different approaches.
Candidates focus on arithmetic (PUM x unit price) and treat the methodology as boilerplate, whereas the examiner grades the reasoning: choice of approach, source of comparables, adjustments and their justification.
What to do instead
Structure every valuation answer as: subject and purpose -> approaches considered -> approach chosen and why -> data sources -> adjustments with justification -> reconciliation -> final value with confidence statement. Never give a number without the chain of reasoning that produces it.
Preparing a kosztorys using the wrong method (inwestorski vs ofertowy) or the wrong basis (KNR vs individual norms), and omitting narzuty, koszty pośrednie, zysk and VAT.
Candidates learn the elements of a kosztorys as a list but do not practice the difference between the methods and the order in which the elements are applied, so the final price is structurally wrong.
What to do instead
Practice building a full kosztorys for a simple scope: przedmiar -> jednostki -> normy -> ceny jednostkowe -> koszty pośrednie -> zysk -> VAT. For each method, write down when it is used and who prepares it. Check the final structure against the applicable rozporządzenie.
Writing an ekspertyza that states a conclusion (e.g. 'the building is unsafe') without describing the research method, the measurements taken, the normative criteria used and the uncertainty.
Candidates write ekspertyzy as opinions rather than as technical documents; they omit the investigative part and the link between evidence and conclusion, which is exactly what the examiner assesses.
What to do instead
Use a fixed structure: cel i zakres -> materiały i metoda -> badania i pomiary -> analiza wg kryteriów normowych -> wnioski -> ograniczenia i zastrzeżenia. Every conclusion must point to a specific measurement or normative criterion stated earlier in the document.
Ignoring conflicts of interest and the scope of the rzeczoznawca's mandate: accepting an opinion on a matter where the expert has a personal or financial interest, or opining outside their specialty.
Candidates treat ethics as a formality and do not practice recognizing concrete conflict situations (e.g. valuing a property for a party that employs them, opining on a structure they designed).
What to do instead
Memorize the ethical rules of the samorząd zawodowy and rehearse scenarios: identify the conflict, state the rule, state the required action (refusal, disclosure, withdrawal). In every answer involving an opinion, add a sentence on independence and on the limits of the expert's competence.
