BITSWORKS:
Casting of the concrete foundation footing took place yesterday 4th of July 2015. The columns mat and columns were also casted. Total number of columns mat casted was 30nos.

We used 3 bricklayers and 8 labours. The mix ratio for the concrete was 1:2:4 and it was manually mixed. A total of 30 bags of cement (Dangote cement) was used, and we didn't even make a dent in the 20 tons of granite supplied by @dayomide70 (a trust worthy supplier, I was shocked by the quantity I saw compared to the rip-offs am used to, a trial will convince you).

Ur step by step pics are good, we've seen ur column starter but u didn't show us reinforcement to column base. nevertheless, many of ur information are useful God bless u.
