🏗️ RCC STAIRCASE CONSTRUCTION: FORMWORK, REINFORCEMENT & CONCRETING

🔹 KEY CONSTRUCTION COMPONENTS
1️⃣ Base Formwork: Supports fresh concrete and reinforcement.
2️⃣ Props & Bracing: Provide stability and prevent excessive deflection.
3️⃣ Step Formwork: Ensures uniform tread and riser dimensions.
4️⃣ Reinforcement: Provides structural strength according to the design.
5️⃣ Landing Slab: Connects staircase flights and transfers loads.
6️⃣ Side Shuttering: Maintains the staircase width and shape.
7️⃣ Concrete Compaction: Reduces voids and honeycombing.

📐 TYPICAL STAIRCASE DIMENSIONS

✅ Tread: 250–300 mm
✅ Riser: 150–180 mm
✅ Stair Width: 900–1200 mm
✅ Waist Slab: Approximately 100–150 mm, subject to design.
