What is RA 9266 and its relation to
Sec.302.3 of the 2005 Revised IRR?
1) Republic Act or RA 9266 is The Architecture Act of 2004 which took effect
10 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 Registered
Architects;
3) Civil Engineers (CEs) who shall continue to sign and seal architectural
plans, specifications and documents shall still be subject to the application
of 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 architectural
plans, specifications and documents by invoking multiple provisions under
RA 9266 (Sections 20, 29, 31, 32, 34, etc.) and its IRR, specifically Sec. 20.2
of RA 9266 which prohibits acting Building Officials/ Building Officials (or
any other officer or employee of the republic) from accepting or approving
any architectural plans or specifications not prepared in accordance with
RA9266 and Sec. 44 which mandates all public officials to enforce RA9266.

What do the terms carrying capacity, development
control and development potential actually mean (under
the 2005 Revised IRR of the NBC/ PD 1096)?
Carrying Capacity of Lot – the optimized extent of physical development that may be
introduced into the lot without causing undue damage, effects or hardship on the end-users
of the proposed development or on neighboring occupants, entities, properties, lands,
developments or the environment (whether man-made or natural) and with the proposed
building/structure capable of being supported by existing utility, transportation and service
systems or by proposed expansions/upgrading of such systems within the immediate future;
Development Control (for Lots and Buildings/ Structures) – a set of inter-acting
regulations concerning the physical utilization of a lot and likewise governing the
planning/design of spaces and/or the use/occupancy of a building/structure to be introduced
(or already existing) on a lot; development controls help determine in detail the development
potential and/or the carrying capacity of all lots and/or of proposed developments on lots;
and
Development Potential of Lot – the maximum extent of physical development that may be
introduced into the lot, i.e., the erection of the proposed buildings/ structures, after full
compliance with the applicable regulations that need to be satisfied, specifically those found
in the Code, i.e., the PNBC.

12.Caveat
To prevent illegal rule insertions in the printed version of
the 2005 Revised IRR (which happened so many times in the past to
previous editions of the NBC IRR), the following steps should be
taken:
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 Printing
Office (NPO) located along EDSA in Quezon City (between East Ave.
& Quezon Blvd.), i.e., not the National Bookstore!
