Notes & assumptions
- Span limit: 4-12 m. Above 12 m, design as proper minor bridge with T-beam superstructure (separate template). Below 4 m, use Box Culvert instead — slab culvert is uneconomical at small spans.
- RCC grade: M25 minimum for spans > 6 m per IRC 21. M30 for > 9 m. The Builder uses 5.X (M20 nominal) as approximation — engineer should verify and bump to M25 design mix (DSR 4.20.X) manually for critical spans.
- Steel reinforcement uses 150 kg/m³ of total RCC — typical for slab culverts under IRC Class A loading. For IRC AA / 70R tracked loading, push to 180-200 kg/m³.
- Wing walls are 4 nos × full external length × 45° splay outward. Default 3 m length each. Brick masonry CM 1:6 (DSR 6.4.2). For NH / SH applications, switch to RCC wing walls (5.2.2) — more durable.
- Parapet (DSR 5.2.2 used as proxy) is a 150 mm thick × 1.1 m high RCC band on both deck edges — IRC standard safety barrier. Excludes precast crash barrier (W-beam) or stainless steel railing — quote separately if needed.
- Approach slab (300 mm thick RCC × 3.5 m long each side) prevents settlement of approach embankment + provides smooth transition from earthen road to culvert deck.
- Stone-pitched apron (2 m × 300 mm thick RRM each end) protects abutment base from scour. Curtain walls (cut-off walls) downstream/upstream — also recommended, NOT in this BOQ; add manually as 5.2.2 RCC of 300×450 mm cross-section.
- Excludes: bearing pads (elastomeric, ₹3-5k each, 4 nos under deck-abutment junction); expansion joint sealant at deck-approach slab transition; reflective markers + parapet end-caps; signage (warning, restriction); approach road tapering + transition to existing carriageway; dewatering during foundation work (typical extra 15-25% in waterlogged sites); pile foundation if SBC < 100 kN/m².
**Slab culverts / minor bridges** fill the gap between **box culverts** (up to 3 m span) and **major bridges** (12+ m span with T-beam or PSC girder superstructure). The IRC SP 13 + IRC 5 + IRC 21 standard configuration for 4-12 m spans: RCC abutments + RCC deck slab + brick masonry wing walls + RCC parapet + RCC approach slabs + stone-pitched apron. Standard for PMGSY high-discharge cross-drainage, state-PWD minor bridges over canals + small streams, urban service-road crossings. This BOQ Builder generates the complete cost per CPWD DSR 2023.
When slab culvert beats box culvert
**Box culvert** is the right answer for spans 1-3 m: monolithic raft + walls + deck slab forms a closed box, simple to construct, economical at small spans. **Above 3 m span**, the box-culvert raft becomes very heavy (deflection control needs disproportionately thick raft) and economics flip. **Slab culvert** uses an OPEN-BOTTOM design (just abutments on either bank, no raft connecting them) — saves significant concrete volume + allows the stream to flow over natural bed. The economic crossover is around 3-4 m span. Above 12 m, slab self-weight becomes excessive; T-beam superstructure (separate beams supporting a thinner deck) becomes more economical → proper minor bridge.
Construction sequence + IRC standards
(1) Earthwork in foundation trench, both banks. (2) PCC bed below abutment foundation. (3) RCC abutment foundation (raft strip, full deck length × abutment-base width). (4) RCC abutment walls (vertical or slightly battered, full deck length × abutment height). (5) Curing of abutments (minimum 7 days). (6) Centering of deck slab (props from natural ground or from temporary scaffold). (7) RCC deck slab (span + 0.3 m bearing seat each side). (8) Curing of deck (14 days minimum per IRC 21). (9) Wing walls cast or built. (10) Approach slabs (RCC 300 mm thick) at both ends. (11) Parapet on deck edges. (12) Stone-pitched apron at base of abutments. (13) Backfill around abutments + approach road tapering. (14) Removal of centering after 28-day cube test ≥ design strength.
Frequently asked questions
Using CPWD DSR 2023 rates for default 6 m span × 7.5 m length × 500 mm deck + 2.5 m abutment + wing walls + parapet + apron: approximately **₹14-18 lakh**. State PWD rates run 8-15% below DSR. Per-span-metre: roughly ₹2.3-3.0 lakh per metre of span. Compared to a box culvert of equivalent discharge (1.5×2 m span at 6 m would be ₹10-12 lakh), slab culvert is roughly 30-40% more expensive but handles much higher discharge.
