Sikkim B&H Schedule of Rates
About Buildings & Housing Department, Government of Sikkim
Sikkim — fully-hilly mountain state with elevations from 280m (Melli, southern border) to 8,586m (Kangchenjunga summit) — has unique construction conditions: no plain area, monsoon May-September, snow at higher altitudes. The Buildings & Housing Department handles state-funded buildings (offices, residential quarters, schools, health facilities) across Gangtok, Namchi, Singtam, Ravangla, Pelling and the rest of the state. SOR is referenced in B&H circulars and tender NITs rather than as a standalone consolidated public PDF. Engineers preparing Sikkim B&H tenders work from the most-recent NIT annexure plus SOR-2020-era references that surface in various tender documents.
Frequently Asked Questions
Why isn't there a public Sikkim SOR PDF?
Sikkim's small tender volume and decentralised B&H organisation distribute SOR as part of tender NIT annexures rather than as a standalone public booklet. This is similar to Meghalaya's pattern.
What rates apply for state-funded buildings?
The most recent NIT annexure rates from B&H Dept Sikkim, supplemented by CPWD DSR (current edition) for items not in B&H references.
How does altitude factor in?
Altitude-tier multipliers are applied based on project elevation: lower-region (Melli, southern Pakyong, ~500-1,500m) baseline; mid-region (Gangtok, Namchi, ~1,500-2,500m) +15-20%; higher (Tashiding, Nathula approach, ~2,500-4,000m) +25-40%.
What about Roads & Bridges?
Sikkim PWD-R&B (separate from B&H) handles roads. Border-area roads (Indo-China, Indo-Bhutan) are BRO. Strategic alignments use NHIDCL framework.
Is JJM-Sikkim covered here?
JJM-Sikkim is implemented via Rural Development Department referencing CPHEEO Manual + B&H civil rates. Sikkim's terrain makes water-supply schemes particularly engineering-intensive.
