Making absolutely certain: Independent third party review.

As independent, officially appointed, and state-certified check engineers, we offer design and construction checking that make a strong contribution to ensuring structures are safe and are guaranteed to deliver sustainable quality and consistent value. We review the structural design, the structural calculations, and the relevant implementation plans on a double-check basis, and perform random checks on site to ensure the due and proper implementation.

The timely inclusion of our check engineers in the design process means your plans are fit for approval and realization – regardless of how complex the construction project. Our clients range from public building authorities, waterways administration bodies and railway and civil engineering authorities through to private customers.
