Engineering services
ConstructTools is run by a practising structural engineer. For project-specific structural calculations, reinforcement drawings or steel-structure checks, mention it in your email and we will tell you whether we can help.
Please note: we cannot approve or certify a design by email. For permits and construction, always use a locally licensed engineer.
