Frequently Asked Questions
Essential answers regarding steel construction, energy targets and project delivery.
No. These are architectural starting points. Certification is shown only when an applicable building certificate is available. Ask for a project-specific design and verification scope.
You can submit an enquiry about an existing design. Adaptation to steel construction, the site and the energy target is reviewed before manufacture.
The four material package definitions exclude foundation and excavation work. Local foundation design and construction must be assigned explicitly in the quotation.
No. Funding eligibility depends on the destination programme, applicant, project and application conditions. The responsible local specialist must check the current route.
The country list is an information guide. Transport, installation and local project support are confirmed for the individual destination and scope.
Timing depends on design completion, local permissions, procurement, manufacturing and site readiness. Ask for a dated programme with responsibilities and dependencies in the offer.
The applicable terms are stated in your contract and relevant product documents. Do not infer a project warranty period from a generic website or catalogue statement.
No. It prepares a message that you review and send in WhatsApp. You can also copy it and email SerVilla.
