my garden project needs removal of 100 cubic meter local soil and build 20 meter new retaining walls. 15 meter of those are 1.4meter high and the rest 5 meter 2.2 meter high. I have got a quote of 18k for the walls including footing and drainage to build reinforced retaining walls. I am from southwest and wonder what is the best price I should look for? there is a vehicular access to site for 8 ton excavator and material delivery.
thanks
