(OP)
We are planning to fill a certain area. The filling will be about 3m high... do we really need to conduct soil testing for this?

RE: Filling Works
The most frequent claims in civil engineering contracts are on the basis of inadequate SI or obstructions resulting in extra costs which could not reasonably have been foreseen by an experienced contractor.
An incomplete appreciation of the ground conditions, which is presented at the construction bidding stage, can only cause the Contractor problems, which will inevitably increase the final cost to the Client. The adage "You pay for a site investigation whether you have one or not" Prof Stuart Littlejohn (1991) is backed up by many civil engineering studies.
These studies and many others have established that one of the largest elements of technical and financial risk in civil engineering projects is unforeseen ground conditions (Institution of Civil Engineers, 1991; Littlejohn et al., 1994; Whyte, 1995). Experience has shown that a modest expense in ground investigation expenditure at the outset could have been repaid many times in reduced project cost over-runs.
Generally the investigation is not a significant cost to a project and comprises from only 0.1% to 5% of the project cost.
Lack of a geotechnical investigation may lead to;
Failures where many case histories are available and;
Significant delays and increases in construction costs when the design has to be revised or amended.
