Section 5 – Preparation of the Bill of Quantities Item 5.6 - Daywork of CESMM-3 has now replaced
with more explanation for application of Preambles. As the CESSM-4 is neutral from contract [Reference to
“ICE Conditions of Contract” removed] and specification [Reference to “British Standard” removed] it is now necessary to show compatibility between the Method of Measurements and the Conditions of Contract used on the project. To address this a schedule must be included in the
Preambles to the BoQ. Schedule shall indicate clauses in the Conditions of
Contract that define the terminology used in the Method of Measurement.

Section 5 – Preparation of the Bill of Quantities (Contd.) Item 5.7 Daywork Schedule
Reference given in CESMM-3 to Schedule of Daywork rates published by the Federation of Civil Engineering Contractors in the UK has been omitted – in order be a very neutral Method of Measurement.
Section 5 – Preparation of the Bill of Quantities (Contd.) 5.18 Provisional Sums In CESMM -3, Provisional Sums for specific
contingencies shall be given in the General Items of the BoQ. In CESMM -4, Provisional Sums for Defined Work shall
be included where work is known to be required. (within the respective Bill/Part).

Section 6 – Completion, pricing and use of the Bill of Quantities (Contd.) Item 6.1 Insertion of rates and prices CESMM -3 specified the pounds sterling and pence as
the currency to be used in the BoQ. CESMM-4 currency to be used shall be as per the
contract (which is to be stated in the Preamble – Schedule – referred in the item 5.6) This is another sign of globalizing of the CESMM-4
Section 6 – Completion, pricing and use of the Bill of Quantities (Contd.) Item 6.3, 6.4 and 6.5 - Adjustment Item The Clauses noted in the Conditions of Contract of ICE
have been removed in the CESSM-4. This will leave to Employer to use his own “Form of
