I have a retaining wall bid that I need some assistance with. Materials will be supplied by the GC. This wall will be 880' x 4' high total. Basically I need help on the labor aspect of this job. I will have to excavate the footing, place drainage and gravel, geogrid, and all courses of block. I will be using the compac unit by keystone. I have already completed aprox 120' of this wall about six months ago while working for another person. Long story short the GC fired the contractor I was working for and now the GC has contacted me to finish the job. I feel like this job on the low side should be atleast 38,000. Do this sound like a good number? my only expenses will be gas to the sight and a place to stay. I estimate that it will take aprox a month to finish this job with only two people. So let me have it, what do you think??
