Despite subclause (3) or subclause (4), if any 2 points of support of a load receptor are so close together that the test load cannot be distributed as required by subclause (3) or subclause (4), as the case may require,—
(a)
both the load and the area specified in subclause (3) or subclause (4), as the case may require, must be doubled; and
(b)
the load must be distributed on both sides of the axis connecting the 2 points of support.
