MEASURING COMPLETED

INSULATION METHOD B

Applicable where the contract has

quoted unit rate per square metre

of completed insulation. Areas of

completed insulation will be

measured as defined in attached

schedule. Should there be any

items not detailed, the client and

the contractor are to agree a

system of measurement in

advance.

Notes:

All external insulation is

measured over the outer surface

area of the completed insulation.

All internal insulation is

measured over the surface area,

which has been insulated. The

method establishes actual areas of

insulation, and makes no extra

over allowance for difficulty of

work as regards formwork or

height. Should the contractor

wish to charge an increased rate

for difficult work he should

specify to which items the quoted

increased rate will apply.

Quantities shall be calculated to

the nearest whole number (0.51

and larger to the whole number

above).

GENERAL

Cut-outs under 1.0m2 are not

deducted. End cap areas are

measured to establish the actual

surface area of insulation. Cut

outs in such areas are treated as

follows:

a) If gross area of end cap is less

than 1,0m2 cut-outs are not

deducted.

b) If gross area of end cap is

1,0m2 or greater, deduct cut-outs,

but subject

to rule (a) above.

c) Pockets, niches, flattening shall

be measured as if the cladding

remains

symmetrical.
