GB 50500-ын дагуу иж бүрэн нэгжийн үнийг бүрдүүлэх

Open the bill, find the section and the item you are pricing, and read the item description and its code before you price anything. The code tells you which schedule item this is; the description tells you what the rate has to cover.

Яагаад: Under GB 50500 the item description is the ground for what the rate includes, and most final-account arguments start with an item whose description did not say enough. Reading it before you price is the cheapest minute in the whole exercise.

Put the prices you actually buy at into the resource catalog: wage costs by trade, material prices by supplier, plant by the hour. Keep them current rather than accurate once a year.

Яагаад: The rates a contractor is judged on are the firm's own, and a published average is a starting point rather than an answer. Holding them centrally means the next hundred rates you build are consistent with this one, and a price change is one edit instead of a hunt through old bids.

Enter the labour, material and plant the item consumes per unit, then open the rate analysis on the line. It shows the direct cost per unit, the management fee, the profit, the comprehensive unit rate and the item total, in that order.

Яагаад: That sequence is the composition GB 50500 defines, and seeing it as a chain rather than as a total is what lets you answer a client who asks why the rate is what it is. The fee and the profit are taken on the direct cost, so the measure items, the statutory charges and the tax stay where they belong, on the bill total, instead of inflating a rate from the inside.

Run the bill through validation. For a project in China the GB 50500 rules are selected for you: every item has to carry a code, and the code has to be well formed at nine or twelve digits.

Яагаад: One item left at zero can carry a loss all the way to site, and a malformed code is the sort of thing an owner's reviewer finds before you do. The check is on the shape of the code rather than on its membership in the national schedule, so treat a clean run as a floor and still read the codes yourself.

Report the priced bill, and keep the rate analysis for the items that carry real money. The analysis is the document you bring to a rate query, not something you rebuild when one arrives.

Яагаад: A rate you can take apart in a meeting settles a query in ten minutes. A rate that exists only as a total turns the same query into a week of reconstruction, and every reconstruction after the event looks like an argument rather than a record.
