Civil works are under way at the headworks, the headrace culvert, the powerhouse and the permanent camp at the same time, with day and night shifts on the concrete fronts. Main electro-mechanical equipment is in manufacture. Milestones below are as at 2 October 2026.
EPC contract for Lot 1 signed.
Site mobilisation. Access road to the site improved, village road widened and levelled, temporary camp and site office established.
Diversion channel, cofferdams and powerhouse excavation. Aggregate crushing and concrete batching plants commissioned. Permanent camp construction begins.
River closure of the main channel achieved; the Malagarasi now flows through the diversion channel.
Upstream cofferdam clay core closed (14 Aug); first blast for the dam foundation (18 Aug); dewatering of the dam pit begins (21 Aug); headrace culvert concreting continues with night pours.
Upstream cofferdam raised above EL 834 m and the dam pit kept dry by three pumps. Foundation excavation for dam blocks 7–9 under way and the cut-off trench being cleaned. Culvert bedding concrete cast bay by bay, with formwork now at chainage 0+930–0+970 and backfill concrete being placed at the downstream transition into the surge tank. Powerhouse sump-pit floor reinforcement accepted and the unit 2–3 foundation slab being reinforced; aggregate and batching plants running to feed the pours.
First structural concrete of the powerhouse placed in the sump pit (EL 785.4–786.9 m).
First dam concrete; unit 2–3 foundation slab concrete; culvert box sections and surge-tank backfill; expansion of the workers' camp; delivery of hydro-mechanical and electro-mechanical equipment.
River closed and both cofferdams in place, the upstream one above EL 834 m. With three pumps keeping the pit dry, the foundation of dam blocks 7–9 is being excavated and the cut-off trench cleaned.
