To prevent illegal rule insertions in the printed version of

the 2005 Revised IRR (which happened so many times in the past toprevious editions of the NBC IRR), the following steps should betaken:

a) the DPWH must be the only and solely designated

copyright holder to the 2005 Revised IRR;b) the only official source of the document (in either hard or

soft versions) should be the DPWH; and

c) the only official publisher should be the National PrintingOffice (NPO) located along EDSA in Quezon City (between East Ave.& Quezon Blvd.), i.e., not the National Bookstore!
