Truck Cost Estimate
Concrete trucks may also charge a "short load" fee for partially filled loads. Short load fees are charged at about $17 for every yard not used on the truck.So for a 10 cu/yd Truck Load - 9.8 cu/yd concrete = 0.2
0.2 x $17.00 = $3.40
$1,056.15 + $3.40 = $1,059.55

*6 inch pours and under.
**Cost assumes subbase and general prep is done.
With a brief look, a 17x31 area at 6 inches deep, you would need approximately 13.86 tons or 9.76 cubic yards of gravel.
Concrete reinforcing is also recommended in high traffic areas and medium to large areas. Wire mesh on average costs $0.56 per sq ft and fiber mesh costs $0.13 per sq ft.
So for your 527 sq ft area, this may roughly cost $295.12 for wire mesh, $1,581.00 for thicker wire rebar mesh and $68.51 for fiber mesh.*Reinforcing for 10 inch pours and under.
6 / 12 = 0.5 ft depth
527 * 0.5 = 263.5 cu ft
263.5 / 27 = 9.7592592592593
= 9.759 cu/yd
