I am not asking what to charge. I have never built a tall wall with engineered plans and geo grid. I am bidding one now and have NO idea how much time it will take to compact all the back fill 6 feet behind the wall. The wall is a total of 375 face feet. Wall specs are 15 feet @6 tall, 30 feet @ 4.5 tall, 12 feet @ 4 tall, and 15 feet @5 tall. These heights are total wall heights included the buryed courses. Access is decent and all backfill soils will be trucked in. Normall for me a 375 face feet wall would be a 3x125 ft wall. Me and my 2 guys would spend no more then 5 days their start to finish. Thats with excavation, clean up, reseeding, etc. This wall will be excavated for me, and reseeding, etc will be priced differently. So whats a close estimate of man hours for this? Block will be techo quarry stone. Will have a large compactor on site (10k lbs unit) and minix and skid. I am figuring 7, 8 hour days with me and 2 guys. Am i over or under estimating this? I have no experience with how long it will take to compact the reinforment zones.
