Got a call from a guy today that lives on the top of a hill looking down towards a nice lake. He wants to build at least 1 retaining wall in the back yard as it is a steep drop and turf is not growing very well near the top. Proposed is to build a 122' long 4' tall wall across the entire property and to back fill and regrade turf area at top to be more level. We will be yanking out and grinding over 20 stumps on the hill side and grade and replant area under wall. At the bottom of the hill near an access street, he wants to build another wall 122' long and 4' high instead of sloping hill towards street as steeply. He also wants to build a staircase going from the top of the hill where the first wall is down to the service street because his boat dock and the lake is across the service street and down another hill. The lower wall is being questioned because it will be 2' below the Georgia Power pole and 2' behind a fire hydrant. I will call the city tomorrow and find out what we are allowed to do near them. The upper wall will go mostly straight across just above where the Georgia Power pole's support lines are. The homeowner said he would supply the blocks since he has found his own supplier of what he likes. I'm ok with that. I figured It would take a full day to prep the hillside for a wall, another day to get the base dug and created, and at least a day and a half?...maybe longer to build the walls, another day to back fill and compact everything, another day to landscape the hill and lay sod in the back of the property, and another day for possibly planting the foundation to his new home. so 6.5-7+ days of work!! I figured 10 hr days $95/hr = $6175-6650+ + MATERIALS: crusher run/soil - $1000 Machine expense: $1500 Fuel/truck charge: $350 + Sod: ~10 pallets-$750 + Plants & Trees: $2500-4000? = around $12,750-14,275 I must say, this is the largest landscaping job I've bid on so far... I really do not have a lot of experience in building walls on a slope like this or grading on a steep slope either!! Any advice would be appreciated! Thanks for reading.
