Concrete Recycled Content Value Calculation Assistance Request:

Can you tell me if I am looking at this correctly if I choose to treat the entire concrete assembly as one entity and do not separate out the SCMs? I have $647,167.33 in total material cost for the concrete. 19% of this by weight is Fly Ash that has 100% pre-consumer recycled content. Another 9% by weight is Portland cement that has 8.5% pre-consumer recycled content. The rest is made up of components that do not have any recycled content. To determine the concrete’s pre-consumer recycled content do I add the following numbers: $122,961.79 (this is 19% of the total concrete material cost, 100% of which is pre-consumer Fly Ash) $4,950.83 (this is 9% of the total, or $58,245.06 and then 8.5% of that number which is pre-consumer Portland cement) So the total pre-consumer content value of the concrete assembly is $127,912.62 – right?
