The estimating methodology for the earthworks for C2 North Portal Chiltern Tunnels to Brackley section of the Phase One route and for the preferred Phase One aerial route at Wendover used by HS2 Ltd is the Civil Engineering Standard Method of Measurement (CESMM4).

In calculating the cost of earthworks along the Phase One and Phase Two route, HS2 Ltd created parameter cost models for all major civil assets including earthworks. The parameter cost models allowed HS2 Ltd to produce a consistent approach to the production of bottom up estimates for each type of asset incorporating cost drivers specific to HS2 Ltd.

These were then used by HS2 Ltd to provide detailed specific earthworks costs based upon specific quantities and cost drivers.
