Our project involves the demolition of a three story brick office building and the adaptive reuse of an adjacent and larger manufacturing/warehouse facility. The warehouse will be converted into a 108,000 SF office building with structured parking. The landscape plan includes 100% stormwater retention and native or adapted vegetation.The site plan results in a deficit of 22,000 yards of fill. Our plan is to recycle a substantial portion of the brick office building (slated for demolition), then crush all clean brick, CMU, and concrete from the demolition to help make up the deficit in site fill. We are also obtaining enough used PZ40 sheet pile to complete all of our retaining wall needs.In both cases we are eliminating the need for virgin building material (new retaining wall material and virgin crushed stone fill) that would otherwise have to be purchased new. We want to make sure both used materials, 1) used PZ40 sheet pile, 2) crushed brick/CMU/concrete, can be claimed under MR 3.1 and 3.2 as reused resources.
Although the project has reduced demand for virgin building materials for the construction of the retaining wall and fill material by "remanufacturing" materials obtained from the demolition of an existing on-site structure, the intent of the credit is not being achieved. The intent of MRc3.1 is to extend the life cycle of building materials through re-use rather than re-manufacture.The project might consider approaching these materials from a construction waste standpoint by including them in the total waste generated. The total weight of the re-manufactured materials could then be counted as diverted from landfill. Applicable Internationally.
