QA/QC is for additional measuring equipment/tool and large flat table, for this can you check with QA manager, what actually needed.
Sure we can cut foundation by 2/3, you should know local pricing for this.
Also for other equipment, can you check Direk if the amount make sense.
I always take high estimate number, as you never know if we missed a thing or two. And it’s very difficult to get additional budget half way the project or once the CAR is approved.
