Which softwares can be used for estimation of construction project time and quantity?
I want to what is height of instrument and Rise & fall method of levelling? What is the method to calculate reduced level.
Height of Instrument (HI) method: consider the readings taken in the operation shown below: Reduce level can be computed using the following expression: RL of a point = HI - FS = ( RLBM +BS) - FS Arithmetic check: ΣBS - ΣFS= Last RL - first R Where: RL: Reduce Level HI: height of instrument FS: foreRead more
