Example No. 1
On 2 February 2010, the Engineer issued revised drawings to show an
additional staircase between the Ground Floor and Basement Level 1.
The work detailed on the revised drawings constitutes a variation
which has resulted in additional concrete works, masonry, metalwork
and decoration.
The additional price to which the Contractor is entitled is £5,321.
A review of the above immediately raises the following questions:
1. How were the revised drawings issued?
2. Which drawings were revised and what are the revision numbers?
3. Why does this instruction constitute a variation?
4. Why does this result in an entitlement to additional payment?
5. How has the claimed sum been calculated?
A reviewer would therefore have diffi culty in reaching a determination
in the absence of such vital information. The following example shows a
more satisfactory approach:
