Today, "CALC ECH RACHID" is more than just a file; it’s a symbol of community-driven engineering. While modern, expensive BIM software exists, this humble Excel sheet remains a staple for quick site calculations because it represents the expertise of a local engineer who wanted to make his colleagues' lives a little easier. He named it (often short for Calcul d'Escalier par Rachid )
The story begins with , a dedicated Algerian engineer or educator who recognized a recurring pain point in his field: the tedious, manual calculation of staircases (Escaliers) and reinforcement (Ferraillage) . Generate technical data for rebar reinforcement
Rachid didn't keep the tool behind a paywall. He shared it on civil engineering forums, Facebook groups, and specialized Algerian educational sites.
