PREPARATORY WORKS AND TESTING
After replacing the top bad mater ial on site, the RIC will fo llow the comp let ion of vibro compact ion.
6.1 Preparatory Works
The compaction area will be fr ee of obst ruct ions and other trades.
A ground survey of the tria l area is to be undertaken prior to the compacti on works starting
(main contra ctor) , the survey is to extend at least 6m beyo nd the compaction area.
The tr ial area is to be set out by GPS with visible markers on the ground for operator guidance.
The locat ions of the Pre Compact ion three CPT's will be identi fied and marked.
6.2 Tr ial Area
Menard proposes an area of 24m X 24m for the t rial of the rapid im pact compact ion method. The
com pact ion pattern wi ll be executed fo llow ing the number orde r shown below, which will result in a first set of compac t ion points based on an init ial Sm grid spacing with a finer second set 2.Sm gr id spacing in
between.
The comp act ion pattern for t he tr ial area is shown in Figure 4. Two pre and post CPTs are proposed to be carried out .
