Calculation Service

A reliable quotation starts with an accurate calculation.

Working from your tender documents, our calculation team establishes which system materials a specified element requires and the quantities behind them. The calculation runs in SchüCal and JANIsoft, so what reaches your quotation reflects current system data rather than an estimate.

An accurate basis for your quotation

Our calculation covers Schüco and Jansen systems in aluminium and steel, from single elements through to complete façade constructions.

What you receive is a structured breakdown you can price against, prepared by specialists who work with these systems every day.

How we support your calculation process

Four areas of support, from the first reading of a bill of quantities through to project-specific solutions.

System material calculation

We establish which profiles, components and accessories a specified element requires, down to the quantities you need in order to price it.

  • Profiles, components and accessories per element
  • Quantities derived from the specification
  • Schüco and Jansen systems in aluminium and steel

Clarity on tender questions

Where a bill of quantities is ambiguous, incomplete or written around a different system, we interpret it with you and identify the technically equivalent solution from our portfolio.

  • Interpretation of ambiguous or incomplete documents
  • Technically equivalent systems from our portfolio
  • Open questions clarified directly with your team

Calculation bases from tender documents

For metal fabrication companies, we prepare the calculation basis directly from the bill of quantities, so your team prices the job instead of decoding it.

  • Calculation basis built from the bill of quantities
  • Structured breakdown of the system material required
  • Adjusted as the specification develops

Special and non-standard projects

Where a project calls for unusual geometries, demanding performance requirements or a solution outside the standard range, our technical consultation team works the case through with you.

  • Unusual geometries and element formats
  • Demanding performance requirements
  • Worked through with technical consultation

From your tender documents to your calculation basis

Most quotations fail on what is missing, not on what is priced. The earlier your documents reach us, the more room there is to influence the outcome.

Why fabricators rely on our calculation service

A reliable calculation creates certainty before a project becomes an order, and the time and risk taken out at this stage stay out of every phase that follows.

Fewer surprises in the quotation

An accurate calculation reduces the risk of a missing component or an incorrect profile combination. Correcting either one during the tender phase costs a fraction of what it costs once the order is placed.

More time for what matters

Working through a complex bill of quantities absorbs days that production planning can rarely spare. Because our team handles that step, your capacity stays with fabrication, project planning and installation.

A technical second opinion

Because our calculation specialists work across a wide range of tenders and project types, they recognise where a different system solution would meet the same specification more efficiently.

Continuity from tender to fabrication

The data generated during calculation carries through the entire process, from SchüCal and JANIsoft into bills of materials, cutting lists, CAD, ERP and CNC machine control.

Who this service is for

The calculation service is built for the companies that carry the commercial risk of a tender.
