Each quota item states the work content it includes, the unit of measurement, the labour hours by trade, the machine-shift consumption and the material quantities with their waste allowances, so that a price can be built from measured quantities rather than from judgement. The volume explanation at the front gives the scope of the quotas, the general provisions on what each rate already covers, the adjustment coefficients for working conditions such as radiation area and confined space, and the rules for measuring quantities; the chapter notes then add the conventions specific to each group of items. It replaces the 2015 edition. Owners, contractors and cost consultants use it to prepare budget estimates, tender prices and cost control baselines for nuclear power projects in China, and reviewers use it to check that a submitted price is defensible.

This chapter comprises the following items: laying of twisted-pair cables, laying of optical cables, laying of coaxial cables, laying of telephone lines and broadcast lines, laying of special-purpose cables, and placing of cabinets, racks and anti-seismic bases.

Other provisions. The cables laid under this chapter are cables dedicated to communication and to instrumentation and control; control cables, power cables, protective conduits and earthing systems are executed under the relevant budget quota items of Cost Estimation of Nuclear Power Plant Construction Project - Part 7: Nuclear Island Electrical Equipment Installation Works.

The twisted-pair cable laying quotas of this chapter are compiled for systems of Category 6 and below, including Category 6. For cabling system works above Category 6, the composite workday consumption of the quota sub-items used is calculated with an increase of 20%.

Where cables are laid inside an already built canopy structure, the composite workday consumption of the quota sub-items used is calculated with an increase of 80%.

Rules for calculating quantities. The laying, pulling-in and open laying of twisted-pair cables, optical cables, leaky coaxial cables, telephone lines and broadcast lines are calculated in m. Cable laying is calculated by the extended length of a single run: for example, if three cables each 100 m long are laid on one rack, 300 m is calculated, and so on. The additional and reserved lengths are a constituent part of the cable laying length and shall be counted within the cable length quantity. The reserved length where a cable enters a building is 2 m; the reserved length where a cable is led up or down into a trench or onto a cable tray is 1.5 m; at an intermediate cable joint box, 2 m is reserved at each of the two ends.

Fabrication of jumpers is calculated per piece; punch-down termination of twisted-pair cables is calculated per pair; installation of jumper frames and distribution frames is calculated per unit.

Installation of information outlets of all types, pull boxes, information outlet back boxes or junction boxes, optical cable termination boxes and punch-down blocks is calculated per piece.

Twisted-pair cable testing is calculated by link or by information point; optical fibre testing is calculated by link or by fibre core.

Laying of pigtails is calculated per length.

Outdoor erection of aerial optical cable is calculated in m.

Fabrication of optical cable termination joints is calculated per fibre core.

Installation of leaky coaxial cable connectors is calculated per piece.

Installation of packaged telephone terminal boxes, cabinets, racks and anti-seismic bases is calculated per set.
