Question 1
An electrical engineering firm is engaged by a commercial client to design, fabricate, and install a custom main low-voltage switchgear assembly (Hauptverteilung). Under the Swiss Code of Obligations (OR Art. 363 vs Art. 394), how is this contractual relationship legally classified, and what fundamental obligation does it impose on the contractor?
Correct Answer:
It is a contract for work and services (Werkvertrag under OR Art. 363), obligating the contractor to deliver a specific, fully functional, and defect-free physical result (geschuldeter Arbeitserfolg).
Question 2
A Swiss general contractor and an electrical installation company incorporate SIA Standard 118 into their construction contract. Fourteen months after formal acceptance (Werkabnahme), the building owner discovers an intermittent neutral connection in a sub-distribution panel. How does SIA Standard 118 Art. 172/173 govern the owner's defect notification rights (Rügefrist) compared to the statutory Swiss Code of Obligations (OR Art. 367)?
Correct Answer:
Under SIA 118 Art. 172/173, the owner benefits from a 2-year guarantee period during which any discovered defect may be notified at any time, whereas statutory OR Art. 367 requires immediate notice upon discovery.
Question 3
Under the Swiss Low-Voltage Installation Ordinance (NIV / SR 734.27 Art. 8 & 9), what legal qualification qualifies an individual as technically competent (fachkundig) to hold a General Installation Permit (Allgemeine Installationsbewilligung) for an electrical contracting enterprise?
Correct Answer:
Holding the Swiss Federal Master Diploma (Höhere Fachprüfung HFP) as a Dipl. Elektroinstallations- und Sicherheitsexperte/in (or equivalent tertiary electrical engineering degree recognized by ESTI with required practical practice).
Question 4
A sanitation and heating company employs service technicians who frequently disconnect and replace circulation pumps and water heaters. Under NIV Art. 15, what is the exact statutory scope and limitation of an Appliance Connection Permit (Anschlussbewilligung für besondere Anlagen)?
Correct Answer:
It authorizes the holder to connect, replace, and disconnect fixed electrical equipment and appliances from the dedicated connection point, without altering or extending the upstream installation.
Question 5
An electrical contractor prepares a cost estimate according to the EIT.swiss calculation methodology and NPK 581. The base direct labor cost (Grundlohn) is CHF 45.00/h. Social security overhead (Lohnnebenkosten LNK) is 30%, production overhead (Fertigungsgemeinkosten FGK) is 60% of direct wages, administrative/sales overhead (Verwaltungs- und Vertriebsgemeinkosten VGGK) is 18% of manufacturing costs (Herstellkosten), and profit & risk (Gewinn & Wagnis) is 8%. What is the resulting charge-out rate (Selbstkosten + G&W) per hour?

Approximately CHF 115.80/h to CHF 119.30/h
