Water, Heating and Waste Services

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 when measuring cold water supply and waste services:

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

• (2) Underground service and rising service/main from site boundary up to cold water storage tank, including any stopvalves, holes through walls, ceilings and floors, insulation to pipes, and the like.

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

• (4) Cold water storage tank or cistern and associated work, such as supporting bearers, overflow, cover and insulating lining.

• (5) Down services with branches, including any stopvalves, holes through walls, ceilings and floors and insulation to pipes.

• (6) Sanitary appliances such as sinks, washbasins, baths and water closets — supply and fixing, including supporting brackets, taps/bib cocks and the like.

• (7) Traps and waste pipes to appliances.

• (8) Discharge pipes (waste, soil and vent pipes) and associated work.

• (9) Any other work connected with the installation, such as painting pipes, marking the position of pipes and testing the installation.
