Hi,

Need some assistance in buildig up the as built productivity.

I was thinking of classifying under such category as below

Excavation

Bored pile

Pilecap

Raft Slab

Ground beam

Column

Slab

Any idea what unit should I use if I were to build this in relation to resource usage as well. Should I use qty/day, or manday/qty or any other suitable unit ?

Any idea to improve on these? Or should I split further into rebar, formwork, etc

    Hi,

    I will do so for my own project

    Excavation - m3 / mday or m3 /eqpt

    Bored pile - lm / mday

    Pilecap - No./mday (not sure)

    Raft Slab - m3 / mday or m3 /eqpt

    Ground beam - m3 / mday or m3 /eqpt

    Column - m3 / mday or m3 /eqpt

    Slab - m3 / mday or m3 /eqpt

    As most the building related work is related to concrete, we usually calculate using m3 / mday. If needed, m3 / eqpt to show the needs for concrete pumps, vibrators.

    Will not split into rebar, formwork. Calculate these together in its entirety. Do take note of the 72 hours allowance for formwork stripping if needed.
