The below tables contain cost data obtained from a bridge project that used three reinforcement options: traditional rebar, WWR small mat (manually placed) and WWR large mat (mechanically placed)
Table 1 Shows the total cost (material and labor) for each option. Notice WWR material cost is higher than rebar. Even with higher material costs it is more economical than rebar.
Table 1 – Cost Comparison of Rebar and WWR Reinforcement for Kenilworth Bridge.
Table 2 Shows the cost comparison for each option adding WWR material waste cost and a higher labor cost. WWR is still more economical with both adjustments.
