Measurement of Plumbing Installations

Abstract

As with the measurement of most other types of building work, it is important to adopt a logical order of ‘taking-off’. The following order is frequently followed in practice:

• (a) Connection to water undertaking’s main and all work up to boundary of site, including reinstatement of public highway and provision of stopcock near the site boundary.

• (b) Underground service and rising main from site boundary up to cold water storage tank, including any stopcocks, holes through walls, ceilings and floors, forming chases for pipes, lagging of pipes, etc.

• (c) Branches to rising main, such as supply to sink, including any associated work.

• (d) Cold water storage tank and associated work, such as bearers, overflow, cover and insulating lining.

• (e) Down-services with branches, including any stop-cocks, holes through walls, ceilings and floors, lagging of pipes, etc.

• (f) Sanitary appliances such as sinks, lavatory basins, baths and waterclosets—supply and fixing, including supporting brackets, taps, etc.

• (g) Waste, soil and vent pipes and associated work.

• (h) Any other work connected with the plumbing installation, such as painting pipes, testing the installation, protecting the plumbing work, etc.
