Overhead and profit (6%) £82,663.20

Total preliminaries £1,460,383.20

The associated measured works came to £5,804,186.49, which meant the preliminarieselements came to 25.16% of the measured works. It is only in understanding the nature of theworks being carried out is it possible to develop up a version of the preliminaries rather thanrelying on a typical percentage addition. This is particularly prevalent in atypical projects.

In the context of this pre-tender estimate the measured works included the following concreteworks:

- Crane bases (Level B3) - Level B3 bases and pits - Level B3 slabs - Level B3 lining walls - Level B3 columns - Level B3 stairs (steps for change in levels) - Level B3 service tunnel - Level B2 slabs - Level B2 upstands - Level B1 slabs - Level B1 upstands - Ground floor slabs - Ground floor upstands - Core A (level B3 to roof) - Core B (ground to level 4) - Core C (level B2 to roof) - Core capping slabs - Below slab drainage - Ancillary items - earthing pits, column strengthening, etc.
