KMRL Schedule of Rates
About Kochi Metro Rail Limited
KMRL is implementing the Kochi Metro across two phases. Phase 1 (operational since 2017, 25.6 km from Aluva to Petta) covers the major Kochi corridor. Phase 2 active NITs (Package KBC3 viaduct + 10 stations, plus depot extensions) extend the network into new growth corridors. KMRL doesn't publish a consolidated SOR — each tender carries its full BoQ derived from Kerala PWD SOR (current edition mirrored on Kerala Forest Dept) + CPWD DSR + DMRC's published Outline Construction Specification adapted for Kochi's tropical-coastal conditions, monsoon construction window, and chloride-aggressive environment.
Frequently Asked Questions
Does KMRL publish its own Schedule of Rates?
No standalone consolidated SOR. Each tender NIT publishes its full project BoQ with rates derived from Kerala PWD + CPWD DSR + DMRC technical specifications adapted for Kochi conditions.
What are Phase 2 packages?
Phase 2 includes Package KBC3 (viaduct + 10 stations from Petta to Tripunithura, then onward extension) plus other corridors. Active NITs accessible at kochimetro.org/tender/.
How does Kochi's coastal environment affect rates?
Kochi's chloride-aggressive coastal environment within 5 km of the Arabian Sea drives M30 minimum concrete with 50mm cover, CRS steel mandatory, integral crystalline waterproofing — adding 8-12% to structural cost above non-coastal baselines. Built into KMRL project rates.
What about monsoon construction?
Kerala monsoon (June-September) drops construction productivity 40-50%. KMRL tender BoQs build in seasonal productivity factors and tarpaulin protection overheads that other regions don't need.
What is the rate fallback?
For general civil items not specifically priced in KMRL project BoQ: Kerala PWD SOR (current edition) + CPWD DSR. KMRL's BoQs explicitly cite these fallbacks in tender clauses.
