RIBNA has estimated 200 m³ concrete and 800 dowels to complete a concrete paving project. 60 work hours is estimated to make dowel baskets and anchor them to the base course. A slipform paver, in 40 work hours, spreads, consolidates, and finishes the concrete slab. On a study date, 600 dowels in 45 work hours and 120 m³ concrete in 30 work hours are used. Based on the above scenario, select the right answer. O The project precent complete (PPC) is 69.00% O The CPIs for the dowel work and the concrete work are 0.8 and 1.0 respectively. O The concrete paving project will be completed 10 hours earlier than its total estimated time O None of the given statements is correct
