Because it was tailored specifically to local construction standards and was remarkably easy to use, it spread like wildfire. Young engineers and students across North Africa began searching for the as a rite of passage. It became so popular that it spawned various "versions" and "updates" as other engineers modified his original work, though the name "Rachid" always remained attached as a mark of quality. The Legacy
In the world of construction, precision is everything. A small error in a riser height or a steel bar diameter can compromise an entire structure. Rachid decided to automate these complex formulas, spending countless hours coding macros and designing an interface within Microsoft Excel. Download CALC ECH RACHID xlsm version
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) . Because it was tailored specifically to local construction
This is the story of a legendary Excel tool that became a viral sensation within the Algerian civil engineering and construction community. The Origin The Legacy In the world of construction, precision
He named it (often short for Calcul d'Escalier par Rachid ). It wasn't just a simple spreadsheet; it was a sophisticated .xlsm file—meaning it contained powerful VBA macros designed to:
Calculate the ideal number of steps and riser heights (Blondel's Law). Determine the necessary thickness of the concrete slab. Generate technical data for rebar reinforcement. The Viral Spread
Rachid didn't keep the tool behind a paywall. He shared it on civil engineering forums, Facebook groups, and specialized Algerian educational sites.
