Patent ID: 6986228

Claim:
An improved method for installing new high rise construction utility waste and vent system plumbing stacks, the method comprising the steps: locating contract plumbing risers on the high rise contract and according to the high rise contract specifications; determining optimum placement within the high rise contract plans of alternative plumbing risers for reduced material and labor costs, improved acoustical benefits, and improved structural benefits; adjusting contract fixture alignment, if necessary, to facilitate optimum placement of alternative plumbing risers; consolidating contract plumbing stacks into optimal groups and one stack; locating newly consolidated plumbing system stacks in contract wall plans; numbering the newly consolidated plumbing system stacks by number and type of materials used; color coding the newly consolidated plumbing system stacks by types of materials used therein; drawing up the newly consolidated plumbing system stacks with the waste riser flow lines consistently on the same stack side facing the stack placement in the wall; listing materials for the newly consolidated plumbing system stacks; assigning proper box sizes to match up with the newly consolidated plumbing system stacks; checking architectural drawings to verify proper clearance for the newly consolidated plumbing system stacks; applying for request for information for walls that may need to be widened to fit the newly consolidated plumbing system stacks; developing pre-fabrication drawings by types of material for each newly consolidated plumbing system stack; numbering each newly consolidated plumbing system stack; identifying any special stack in the newly consolidated plumbing system stacks; finalizing pre-fabrication drawings; preparing a pre-fabrication book to coordinate main distribution piping to match up with the newly consolidated plumbing system stacks; establishing color coding to stack type within the newly consolidated plumbing system stacks; pre-labeling the construction job-site; installing the newly consolidated plumbing system stacks.
