Material and Labour takeoffs on houses ranging in size from 175m2 to 280m2 (majority of houses are single level). We have a standard template that we work form so it is a matter of measuring the items we have listed and inputting the quantity. There are a number of main trades such as plumbing (allow plumbing PC's in take offs), electrical, timber frames and trusses, metal/tiled roofing, plasterboard/drywall, joinery, will not need to be taken off as we get the actual trades to supply us with lump sum prices, all other items will need to be measured and quantified. My company uses an estimating program called buildsoft but this can be transfered into other programs. These houses are not complicated but would require a person experienced in estimating in the building industry. We are revising our plans continuously to fit on new blocks we purchase so the work will be ongoing. The estimated end date I have entered below is for the first job only. I have not been able to attach a plan as this site at this stage would not allow me to do so, I think it is because I am on an iPad?
