1. The present NBC was promulgated 19 March 1977 as PD 1096 by President FM; its various Implementing Rules and Regulations (IRRs) were issued by the MPWTC until 16 July 1979; in 1992, only the IRR section on Permit Fees were amended;

2. In the year 2000, the DPWH re-organized the Board of Consultants (BoC) composed of representatives of accredited professional organizations (APOs) and reconstituted the Building Research and Development Staff (BRDS) into the NBC Review Committee (NBCRC);

3. the BoC was headed by a past UAP President (Angel Lazaro, Jr.) and 36 other member-professionals took part in the 3-year effort to revise only the IRR, which was signed by the DPWH Secretary on 03 Nov

2004, published April 2005 and which took effect 02 May 2005;4. as of 2005, PD 1096 (NBC) is still the only law on buildings as

it was neither amended nor repealed;

1. With the 02 May 2005 effectivity date of the 2005 Revised IRR, the following may now take place:

a. possible DPWH issuance of general information materials for the public; members of APOs like the UAP and the PICE may have their members trained in dissemination work and will be asked to help disseminate information on the IRR; and

b. issuance of the manual of procedure for use by the Building Officials tasked to enforce the 2005 R-IRR; and

2. sometime in 2006, crafting of the bill (the “Building Law”)

that shall fully repeal PD 1096 (NBC) and fully assimilate the Revised IRR of 2005, should be completed; however, this new legislative effort may extend to 2007 and beyond;

1. The 2005 Revised IRR applies particularly to all new structures located in new developments, i.e., along new road rights-of-way (RROWs), new subdivision or estate developments, particularly reclamation areas; rules on foot-printing and setbacks may be somewhat relaxed for new construction within built-up areas or for renovation/ rehabilitation projects; 2. The Revised IRR integrates general design and physical planning concerns, particularly on the matter of the development and usage of RROWs and ROWs and their collective effect on the determination of building bulk inside properties facing RROWs; 3. The building permit shall become a general permit to be first supported by ancillary or accessory permits; and 4. Architectural & Structural Permits are types of ancillary permits.

_________________________________________________________________________________________________________________________________



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.

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!

a Pleasant Morning a Pleasant Morning to You All!to You All!
