Area-scaled items multiply by this area; fixed items (reservoir, PLC, gateway) do not.
Each zone gets its own valves, soil sensors and sap-flow sensor. Smaller zones give finer control but more hardware.
Main items — the core equipment of the project. Move each cursor between its lowest and highest rate.
Auxiliary items — fixation labour, civil works, software, contractor charges and contingency. Switch items on or off, or enter your own quote under “Edit rates”.
One cursor moves every main and auxiliary item together from its lowest to its highest rate.
Rates tagged Sourced come from supplier prices found online (US, UK, Australia, India), converted at 1 USD = 0.376 BHD. Items tagged Assumed or Partly sourced rely on my own estimates. Replace them with Bahraini quotes before using these figures as a tender budget.
