15.3 The ICE standard method of measurement<br />
The ICE standard method of measurement is not mandatory, but the ICE<br />
conditions require the method to be used – ‘unless general or detailed description<br />
of the work in the bill of quantities or any other statement shows clearly<br />
to the contrary’. The most recent (3rd) edition of the CESMM was published<br />
in 1991 with corrections in 1992, and is commonly referred to as CESMM3. The<br />
standard method is not a contract document, and thus is not used in interpreting<br />
the contract – except in so far as its provisions are repeated in the contract<br />
documents (see below). Its use is solely as a recommended method of measurement<br />
in conjunction with the ICE Conditions, and is generally on the basis<br />
that all the works will be designed by the employer or his engineer.<br />
Problems in the use of the standard method. The use of CESMM over a number<br />
of years has indicated several potential problems in the compilation of bills of<br />
quantities and measurement. There are seven introductory sections printed in<br />
the method and, although these are largely guidance notes for people preparing<br />
a bill, some parts need to be included in a contract, such as the parts dealing<br />
with adjustment items or method-related items. Other parts of the guidance<br />
notes may need exclusion to prevent the parties trying to alter the method of<br />
measurement after award of contract.<br />
The parts of the CESMM’s preliminary sections which are needed should be<br />
written into the contract documents themselves. Also the measurement rules<br />
may not apply, or may not be suitable if the contractor is required to undertake<br />
some element of design, such as in providing bearing piles.<br />
However, it is not usual to depart from the units of measurement in<br />
CESMM3, or the measurement rules and coverage rules set out in the Work<br />
Classification sections of the CESMM. The measurement rules say, for instance,<br />
that when measuring concrete volume there is to be no deduction for the volume<br />
occupied by reinforcement, rebates, grooves and holes up to a certain size,<br />
etc. The coverage rules denote, for instance, that an item for supply of timber<br />
components includes their fixing, boring, cutting and jointing. Such rules are<br />
useful in making clear what the bill items are intended to include.<br />
The standard method results in lengthy bills and for some types of work<br />
may seem to give an unnecessary number of items, or to divide work down<br />
into such detail that considerable thought has to be given to billing and pricing.<br />
Modifications to the method must, however, be very clearly put in the<br />
contract in order to avoid the possibility of the parties trying to argue for<br />
re-measurement or additional measurement where this was not intended.<br />
For instance, instead of itemizing painting of step irons, ladders, etc. separately,<br />
a sub-heading can be put at an appropriate position in the bill stating:<br />
‘The following items to include painting after fixing’. The CESMM mentions<br />
that a line must be drawn across the description column in the bill below the<br />
last item to which the sub-heading is to refer. If, however, there is so much<br />
painting to do that a contractor would probably sublet it to a painting subcontractor,<br />
a non-CESMM item might be put in the bill of quantities, such as
