1) Republic Act or RA 9266 is The Architecture Act of 2004 which took effect10 April 2004, while its IRR took effect 01 December 2004;2) Section 302.3 of the 2005 Revised IRR of the NBC (PD1096) is already fully
harmonized with RA9266 and its provisions limiting the preparation,signing and sealing of architectural documents only to RegisteredArchitects;
3) Civil Engineers (CEs) who shall continue to sign and seal architecturalplans, specifications and documents shall still be subject to the applicationof the severe penalties under RA 9266 & its IRR (reference Sec. 29 of RA 9266);
4) The DPWH can still legally bar CEs from signing and sealing architecturalplans, specifications and documents by invoking multiple provisions under
RA 9266 (Sections 20, 29, 31, 32, 34, etc.) and its IRR, specifically Sec. 20.2of RA 9266 which prohibits acting Building Officials/ Building Officials (orany other officer or employee of the republic) from accepting or approvingany architectural plans or specifications not prepared in accordance withRA9266 and Sec. 44 which mandates all public officials to enforce RA9266.

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!
