activities. This will always be coordinated with City of Santa Ana in advance. <br /> RFI's will be issued as needed if questions or scope issues arise during the course of <br /> the demolition activities. Field activities related to any BFI's will not occur until an <br /> appropriate answer has been provided. <br /> 3.1 PRE-STRUCTURAL DEMOLITION ACTIVITIES <br /> AS needed, IDI will use Bobcat skid steer loaders and hand labor to remove all soft <br /> debris that is not easily separated from the concrete material.This includes removal of <br /> roofing, ceilings, HVAC ducts, insulation, plaster partition walls, lights and all other <br /> building components. <br /> Fences will be installed around the trees that are to remain as per the plans in order to <br /> protect them from any damage during the demolition. In addition, they will be <br /> watered weekly, every Friday at Sam utilizing our water truck that is permanently on <br /> site. <br /> 3.2 ABOVE SURFACE DEMOLITION <br /> IDI will begin the above surface demolition after the asbestos and lead abatement has <br /> been completed and as demolition progresses, IDI will use Bobcat skid steer loaders <br /> and hand labor to separate the wood, metal, and roof materials in order to transport <br /> them to a recycling facility. Roof containing concrete will be transported with the clean <br /> concrete to a recycling facility. The wood mixed with trees and shrubbery will be <br /> recycled to be used as combustible. <br /> IDI will utilize excavators and track loaders equipped with special demolition <br /> attachments (i.e. hydraulic breakers, hydraulic shears, and grapples) to demolish these <br /> structures.The use of IDI's excavators increases the efficiency of the demolition <br /> process and allows a more controlled operation than conventional crane and ball <br /> wrecking procedure. Demolition will begin from the top working down and from one <br /> end of the building working towards the other end. Excavators and loaders will <br /> systematically demolish the building structure and process the demolition debris. <br /> Demolition debris will be segregated and stockpiled for proper disposition. <br /> 3.3 SUB-SURFACE DEMOLITION <br /> Sub-surface demolition will consist primarily of removal of building slabs, and footings. <br /> IDI will use excavators to demolish the concrete down to slab or adjacent grade <br /> elevation. Track loaders may assist with debris removal, processing, stockpiling and <br /> loading. Slabs and footings will be broken in place, processed and hauled off site for <br /> recycling. <br /> 3.4 FERROUS AND NON-FERROUS METALS RECYCLING <br /> During demolition of the existing building structure, IDI will process the demolition <br /> debris to recycle as much metal material as possible.
