Structural engineering

Structural calculations, structural site supervision, permit filings and acceptance inspections for new builds, conversions and retrofits.

What we take care of

  • 1Structural calculations for residential and commercial buildings
  • 2Structural site supervision
  • 3Structural filings with the municipality and the province
  • 4Structural acceptance inspections - including ten-year inspections
  • 5Construction details in reinforced concrete, timber, masonry, steel
  • 6Advice on structural options and seismic safety

This list is not complete - describe your project and we will tell you which points are relevant for you.

How we work together

  1. First meeting and site visit: we clarify use, existing condition, ground and goals.
  2. Structural concept: choice of material and system - reinforced concrete, timber, masonry or steel - together with the architect and client.
  3. Structural calculation and detailed design: load analysis, sizing, reinforcement drawings and details.
  4. Filing or submission of the structural documents with the competent authorities.
  5. Structural site supervision: checking execution on site and coordinating with contractors.
  6. Structural acceptance inspection and handover of the documentation.

Time and cost

For a single-family house the structural design usually takes two to six weeks, longer for larger residential or commercial buildings. The effort and therefore the fee depend mainly on the size and complexity of the structure, the condition of the existing building, the number of design changes and whether structural site supervision and acceptance inspection are included. After the first meeting you receive a written quote.

Legal basis

The basis is the Italian Technical Standards for Construction NTC 2018 (Ministerial Decree 17.01.2018) with Circular no. 7/2019 and the Eurocodes, plus the provincial rules for filing, submission and acceptance inspection. Ing. Manfred Lechner is listed in the register of structural acceptance inspectors.

Service area

We work throughout Val Venosta - from Resia, Curon and Malles via Prato, Lasa and Silandro to Naturno - in the Burgraviato around Merano and on request throughout South Tyrol. Our office is based in Prato allo Stelvio; site visits are standard for us. We work in German and Italian.

Frequently asked questions

Is there a difference between structural calculation and structural engineering?

No: both terms describe the same thing - the calculation and design of all load-bearing elements of a building.

Do I need a new structural calculation for a renovation?

Yes, if load-bearing walls, floors or the roof are altered or the use of the building changes. For non-structural work usually not - we clarify this in the first meeting.

Who carries out the structural acceptance inspection?

A registered acceptance inspector who is not the structural designer. We carry out acceptance inspections for other projects and organise them for our own.

Do you also design timber structures?

Yes: timber, reinforced concrete, masonry, steel and hybrid structures.

How much does the structural design of a single-family house cost?

It depends on size, construction type and required performance. With the drawings and a short meeting we prepare a concrete quote.
