Expand production norms into resource quantities
Take a production norm per unit, expand it across the takeoff quantity into labour, plant and material, roll the resources up by trade and carry the resourced rate into the bill.
Cách hoạt động, từng bước một
4 bước xuyên suốt nền tảng - bạn làm gì ở mỗi bước và vì sao điều đó quan trọng.
Pick the norm
Định mức sản xuấtFind the production norm that matches the work item and the conditions - the trade, the material, the difficulty - so the consumption per unit reflects how the job will really be built.
Tại sao: A norm chosen for the wrong conditions carries the error into every unit. Matching the norm to the actual work is where the accuracy of the whole build-up is won or lost.
Expand across the quantity
Định mức sản xuấtMultiply the norm by the takeoff quantity to explode the item into the hours of labour, hours of plant and units of material it will actually consume.
Tại sao: Seeing the raw resource demand, not just a rate, is what lets you sanity check it against your crews and plant. A rate hides an impossible labour figure; the expansion shows it.
Roll it up by trade
Tổng hợp tài nguyênGather the expanded resources across the whole bill into a summary by trade, so you can see total labour hours, plant hours and key material tonnages in one place.
Tại sao: The resource summary is the reality check on the price. It tells you whether the labour you have priced can be manned and whether the material order matches the estimate.
Carry the rate into the bill
Bảng khối lượngPrice the resources at your labour, plant and material rates and carry the resulting unit rate into the bill, where it stands on a build-up you can defend line by line.
Tại sao: A rate backed by a resource build-up survives scrutiny that a lump-sum guess does not. When a client challenges a price, you can open the norm and show exactly what it is made of.
