Measurement Rules (4)
C1 1

The area measured is the area of contaminated land

C2 2

Where the volume of excavation and disposal of contaminated ground material is measured, the volume measured is the surface area of the contaminated material multiplied by the average depth of the contaminated materia

C3 3

Quantities given for disposal of contaminated ground material are the bulk before excavating, and no allowance is made for subsequent variations to bulk or for extra space to accommodate earthwork support

C4 4

Other cost-significant components are to be described and identified separately. Such components are to be measured by area (m2) or linear measurement (m), or enumerated (nr) separately

Included Items (3)
1.

Contaminated ground material removal using dig and dump strategy, including safe disposal of excavated material to licensed tip (non-hazardous and hazardous material), tipping charges and landfill tax.

2.

Contaminated ground material treatment using in situ methods, such as: • dilution • clean cover • on-site encapsulation • bioremediation • soil washing • soil flushing • thermal treatment • vacuum extraction • stabilisation.

3.

Where works are to be carried out by a subcontractor, the subcontractor’s preliminaries, design fees, risk allowance, overheads and profit, with allowance for these to be made within unit rate applied to element or component.
