WHAT IS INNOVATION

Innovation refers to an idea, embodied in a technology, product, or process, which is new and creates value. To be impactful, innovations must also be scalable, not merely one-off novelties. The Strategy for American Innovation” focuses on two broad categories of innovation:

Innovation to drive economic growth and address national priorities

Institutional and public sector innovation

( Kent Shigetomi, Office of the U.S. Trade Representative to Apec, Lima, Peru )

STANDARDS DRIVE INNOVATION

USING AITECH ACCREDITED PPST

In the aftermath of Typhoon Yolanda, many new technologies

were submitted to the Aitech Committee for accreditation. To

date there are 66 accredited technologies. List of accredited

technologies can be found in our website : nha.gov.ph

Likewise in view of the new climatic conditions, structural

standards must comply with the new parameters for

construction. A technical working group on disaster resiiency was

formed by the NHA to arrive at new design parameters for housing.

CHALLENGES ENCOUNTERED IN USING NEW TECHNOLOGIES

not yet so widely accepted by the public; not attuned to culture

warranties sometimes are not assured and even the capability to do it on a mass scale

builders are not well trained on the construction methodology especially so if the don’t own the technology

results to material wastage instead of savings

delays in construction

substandard or poor quality of construction

closed systems do not allow for future expansion or use in combination with other materials

Memorandum Circular 2016-020 : Guidelines Using AITECH Accredited and New Technologies approved on 27 January 2016.

Construction Checklist/Guidelines for the following technologies, completed by January 2016

• The conduct of the Hands-On Training Seminar was createdto educate NHA technical staff and otherdevelopers/contractors on the proper constructionmethodologies of DPWH-approved housing models withAITECH accredited technologies/systems/building materialsfor typhoon reconstruction projects and other NHA projects.

Memorandum Circular 2016-020.pdf



Hands On Training for 186 Technical personnel completed as of

EO June 2016, including Iloilo for 33 personnel conducted on 29

June to 01 July 2016 done in coordination with technology

proponents, to ensure proper installation and methodology

Construction Checklist/Guidelines for New Technologies being

applied in Typhoon Yolanda Rowhouse projects completed by EO

January 2016.( defined what items should be prepared prior to,

during and after construction)

Continuous monitoring of performances by contractors using such

technologies as a regular part of due diligence ( CPES and AITECH

• Proponents of new technologies must ensure that their products are

properly used by builders to protect their reputation and the interest of

the public in general

• The proponents must allocate funds for the transfer of the technology

to end users as part of their marketing cost, and also to promote them

and enable the use on a mass scale to speed up constructioN.

• Developers/Contractors must ensure that they are well versed with the

technology prior to their application to avoid construction errors/ bad

construction

• Government testing centers must likewise be improved for better

quality control and calibration and must allocate funds for such

improvements and conduct researches towards this end.

• APPROPRIATEFUNDS / BUDGET MUST BE ALLOCATED FOR R&D

• Integration of the resiliency principles/ guidelines on design and

construction in our building code which is presently being reviewed by

the DPWH Board of Consultants and its various referral codes (

architectural, engineering/structural, sanitary, electrical and

mechanical, fire, etc.)

• Review of local laws pertaining to settlements and recommend

proposals for a typhoon/earthquake code on specific areas that are

disaster prone/or are in extreme environments

• Review of processes and procedures to ensure compliance to

resiliency guidelines: who will check ? Are they technically competent?

Training for regulators and implementors alike is critical

• Resiliency is not just about strength of buildings but also

on the location/choice of sites and on the way they are

planned.

• It is also about building the resiliency of communities

who are directly affected by calamities and the effects of

climate change. Therefore community/housing

development programs must always be geared towards

this direction.

• Multi-stakeholderparticipation is indeed andtruly a must in anyendeavor both bygovernment and theprivate sector, even withthe use of newtechnologies to achieveresiliency in our buildingsand communities(direction setting, programownership issues, end-user education, expertsadvise, policy relatedmatters, etc.)
