Down here a "cheap" rate is $50/tonne for transport & dumping of soil, that's not including the excavation, you'd be looking at machine hire for that so maybe $500-$1000 per day. The retaining wall is going to be a challenge. Not the length, the height. Normally you go down as far as you go up Re: excavation and retaining wall approximate costs 4Apr 12, 2016 10:02 am A dozer will cost about $1,000/day plus transportation to and from the site. Digging is the cheapest part. These days off site disposal is expensive so if possible use cut and fill to eliminate off site disposal costs. A 4m retaining wall will cause problems for you. It will need to be fully engineered, have water diversion drains and may need to be fenced (as fall protection). I suggest that you consider terracing by having say 3 changes of level. Alternatively, if you are excavating into rock or sandstone you may need to do nothing, Just batter back the excavation and eliminate the retaining wall. Also have a soil test done including drilling some deep core holes to try and find out what surprises lie under the ground.
