1 Scope

NB/T 20358.11-2018 is the Chinese budget estimation norm for the civil works of the conventional island of a nuclear power plant, the eleventh part of the NB/T 20358 series. It is not a technical standard but a price book, and that is precisely what makes it valuable to anyone outside China trying to understand what a Chinese nuclear project actually costs. A budget estimation norm fixes, for every unit of work, the quantity of labour, material and plant that the state considers necessary to perform it: so many labour hours and so much formwork per cubic metre of concrete of a given grade in a given location, so much per tonne of reinforcement, per square metre of finishing. Those figures are the basis on which the estimate is prepared, the tender limit is set and the final account is settled, and they are what a foreign contractor, supplier or analyst needs in order to read a Chinese nuclear cost estimate rather than guess at it. This volume covers the civil engineering of the conventional island - the turbine building and its associated structures, as distinct from the nuclear island covered by other parts of the series. Its fourteen chapters run through the whole trade sequence: manual and mechanical earthwork and rock work, foundation treatment and piling, concrete and reinforcement, masonry, structural steel, waterproofing and thermal insulation, floors and finishes, doors and windows, decoration, and the works of the site, together with the scaffolding, dewatering and other preliminary items. The document is issued as one of the sixteen parts of NB/T 20358, alongside the companion series NB/T 20355, 20356 and 20357 that cover the other stages of nuclear cost estimation. It was issued on 10 December 2018 by the National Energy Administration, took effect on 1 April 2019, and replaces the 2015 edition.
