Supervision Engineer

The Supervision Engineer, in accordance with the Viennese Building Regulations, will be specified to the building permit applicant as the controlling body on behalf of the Building Inspectorate. The Supervision Engineer is jointly responsible with the Site Manager for the compliance with the Building Regulations (OIB (Austrian Institute of Construction Engineering Guidelines) and the Viennese Building Regulations). The responsibility of the Supervision Engineer in accordance with the Viennese Building Regulations is regulated by § 125,127 and § 128 of the Viennese Building Regulations. With the Notice of Completion, the Supervision Engineer confirms the construction of the building in accordance with the application plans (possibly subsequent alteration plans) and the compliance with the Viennese Building Regulations and shall also liable in the event of non-compliances.

The Supervision Engineer in accordance with Viennese Building Regulations should not be confused with the Inspecting Structural Engineer in accordance with OIB RL 1 respectively EN 1990-1. The division of responsibility and relationship to each other is regulated by the Normative Foundations.

The Supervision Engineers


Underground Inspection

Visual inspection of the surface (on the surface of the excavation) is carried out for all rising support structures before concreting occurs along with soil survey inspections on a regular basis.

In the case of apparent discrepancies or differences, the general test and warning obligations apply to all consultants and disciplines involved in the construction.

Normative Foundations

Review during Construction

Inspections (during construction or the building phase) on the basis of valid and allotted application/ substitution plans.

Leading up to the completion of the shell-construction: arrangements for the acceptance of acc. § 127 (3) a) b) c) and inspections of the geometry.

After initial shell-construction inspection: monitoring of expansion parts and geometry.

Examination of Supporting Components

Inspecting of components that cannot be visually inspected upon completion: foundations, steel inserts, beams, columns, welds, etc.

Finished parts are also inspected during their manufacture and assembly, along with externally monitoring quality components before they are approved for execution/ use.

Shell-Construction Inspection

For shell-construction inspection, construction management and the corresponding building progress are required. The shell is the part of the building, which is encompassed by the OIB Guideline 1 (mechanical stability).

All of the supporting components of the restoration must be implemented (well, roof incl. Rafters and ridge purlins, last floor ceiling, cornices, parapets).

Expansion Inspection

For expansion inspection all relevant component properties are to be decided. During consensus-related performances, the conformity of the consensus must be in accordance with building regulations. For apparent variations in the consensus of building regulations, general testing and warning obligations apply to all consultants and disciplines involved in the corresponding construction.

Notice of Completion

Reimbursement of the completion report on behalf of construction advertisers or the owner. Confirmation of the proper implementation of the project along with all detailed findings (i.e. canal results, chimney hood findings, etc.) are provided by the client.

The confirmation of the completion report requires comprehensive knowledge of construction management, which is only possible by means of continuous quality control.

This is precisely the activity of the supervision engineer. At times during practice, inspections in accordance with § 127 (3) are carried out by the structural engineer and confirmation of the completion report can be issued by another individual (civil engineer).


Building Book §128a WBO

On 10/15/2014 it was stated that for a building containing more than two main floors (excluding additions and conversions within the scope of § 68 para 1 and BO elevator additions) a building book is obligatory in preparation of the completion report. All building owners are completely responsible for the preparation of the book, even if they have not yet applied for construction management.

The BO requires these informations to be present within the building book:

  • All data of relevant building permit(s) along with completion report(s), numbers and the corresponding dates of the business decision
  • The names of all parts that are to undergo a periodic review
  • The time of the initial inspection and the interval periods of inspections
  • The prerequisites which the reviewing individuals need to meet
  • The results of all inspections that have been done
