CATEGORY 3 & 4TYPHOONSStructural failure of some buildings. Complete roof failures on many buildings.

During earthquakes

• Well-built buildings suffer slight damage

• Poorly built structures suffer severe damage

• Hillsides might crack if the ground is wet

Page 25: Icw presentation for rallly forum2014dec20

A HOSPITAL IS A BUILDING THAT IS ESSENTIAL TO POST-EARTHQUAKE OR DISASTER RESPONSE AND THEREFORE MUST HAVE:

• Very low risk of earthquake induced- collapse

• Low risk that the building or structure will be damaged sufficiently to impair use in post-earthquake response and recovery efforts

Page 26: Icw presentation for rallly forum2014dec20

WHAT NEEDS TO BE DONE NOW?

1. A THOROUGH ASSESSMENT OF THE STRUCTURE

2. IMMEDIATE AND PROPER REMEDIES (DEMOLISH WHAT CAN NOT BE SAVED, RETROFIT WHAT CAN BE FIXED, REDESIGN WHAT NEEDS TO BE IMPROVED)

3. STRICT COMPLIANCE TO CODES AND DESIGN SPECIFICATIONS

4. FUND SUPPORT

5. PUBLIC PARTICIPATION IN MONITORING THE IMPLEMENTATION

Page 27: Icw presentation for rallly forum2014dec20

WHO ALLOTS FUNDS FOR THE IGH?

- THE DEPARTMENT OF HEALTH THROUGH THE HEALTH FACILITIES ENHANCEMENT PROGRAM (HFEP) WHICH WILL END IN 2015

WHO INFORMS THE DOH ON THE NEEDS OF THE IGH?- THE GOVERNOR, FROM THE PLGU’S PLANS, PROGRAM OF WORKS AND REPORTS

SOME QUESTIONS AND ANSWERS:

Page 28: Icw presentation for rallly forum2014dec20

WHO NEGOTIATES WITH DOH ON FUNDING?- THE CONGRESSMAN AIDED BY GROUND INFORMATION FROM THE GOVERNOR/PLGU

WHO WILL HANDLE FUTURE WORKS OF THE PROJECT? - THE DPWH (DBM CIRCULAR 551 JANUARY 2, 2014)

WHO SHALL SUPERVISE THE NEXT PHASES?- THE DPWH, BEING THE IMPLEMENTOR,

SHALL SUPERVISE

Page 29: Icw presentation for rallly forum2014dec20

CAN THE PUBLIC MONITOR THE PROJECT?

- YES, ACCREDITED CIVIL SOCIETY ORGANIZATIONS CAN NOW MONITOR AND PARTICIPATE IN:• PROJECT IDENTIFICATION• BUDGETING PROCESS• PRE-CONSTRUCTION ACTIVITIES• CONSTRUCTION, AND • POST EVALUATION OF PROJECTS

OTHER RECOMMENDATIONS

Page 31: Icw presentation for rallly forum2014dec20

1. RECOMMENDATION From ICW and Ifugao Professionals:

“…re-analyze the entire structure with a finite element program using the concrete test results and identify failing structural components. If too many components are failing, normally at beam-column connections, I would introduce bracing. Bracing can compromise functionality and aesthetics but “Safety is Number One”. Columns in a braced system would be spared most of the bending stresses from earthquake and wind. They participate as axial members with stresses more uniformly dispersed in their cross section thus greatly reducing stress concentrations. Where flexural members (beams and slabs) are still overstressed with bracings in place, there are a number of solutions including what I described above. With the lowered ultimate strengths used in the analysis, it may become possible to use CRFP to reduce stresses below those strengths if close enough though I would limit its possible use to beams because of the stringent quality controls required that may be difficult to maintain over wide slab areas…” – Arthur Butic, Structural Engineer, USA

Page 32: Icw presentation for rallly forum2014dec20

From ICW and Ifugao Professionals:

“…use thick steel plates all sides welded full height of the columns gunite* with high strength cement to fill up the gap between plates & column….(this) will straighten out the column perpendicularly on center though the column will be bigger in size. YOU CANNOT RETROFIT A VERY WEAK CONCRETE STRUCTURE WITH CFRP. ” – Manny Dulnuan, Engineer USA

*GUNITE - a cement-sand mortar that is sprayed onto formwork, walls, or rock by a compressed air ejector giving a very dense strong concrete layer: used to repair reinforced concrete

IGH MAIN BUILDING AT “SAFE DISTANCE”

NATURAL STORM WATER DRAINAGE “GOHANG, KULU”

2. RECOMMENDATION: ON LOCATION

Page 34: Icw presentation for rallly forum2014dec20

RECOMMENDATION: BUILD PROPER STORM DRAIN CHANNELS TO PREVENT SCOURING OF SURROUNDINGS

Note to neighbors & LGU: no settlement must be built along this natural drain

Page 35: Icw presentation for rallly forum2014dec20

3. FURTHER RECOMMENDATIONS

-DPWH as implementor of next phases to consult the Designers

-MOA provisions to include civil society groups to monitor the project

-Ammend R.A. 9184 or update IRR to include specific guidelines on Phased Projects
