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. In the above scenario, the SPI for the project is: 0.85 O unknown. more information is required. O 1.15 O the same as its CPI
