/ Regional field notes
Northeast India — deployment realities
Climate, logistics and acoustics shift the design when projects move east of the Brahmaputra. Three field notes from sixteen years of regional integration — written for architects and consultants arriving with a central-India template.
Climate · monsoon · lightning
Climate-led design decisions for the Northeast
Humidity above 85% for four months, lightning-strike density five-times the national mean, and ambient temperatures that age battery rooms 30% faster.
Read the field note →Logistics · commissioning · schedule
How Northeast logistics rewrite the project schedule
Inland transit, inter-state checkposts and monsoon mobilisation add 4–8 weeks to a central-India project plan. Plan procurement earlier — do not compress integration.
Read the field note →Acoustics · auditorium · RT60
Auditorium acoustics in the Northeast
Seasonal RT60 drift of 0.3–0.6 s. Polyester / mineral-wool absorbers, per-season absorption coefficients and an annual re-tune as part of AMC.
