H

e was born in the town of Ibajay, in the province of Aklan, on August 9, 1900. His parents, Juan Melchor and Caridad Salguero, belonged to the Filipino middle class. His father his him to the Ibajay Primary School; Kalibo Elementary School, and Capiz High School in Capiz, Capiz, (now Roxas City), up to second year of high school. Alejandro finished his secondary education at the U.P. High School in 1920.

Dr. Vidal A. Tan, one time head of the U.P. Mathematics Department, dean of the College of Engineering, and president of the University, in a letter referring to Melchor, wrote: “Major Melchor was a student of mine in 1920 and was the best in his class and easily one of the best I ever had during my twenty four years in teaching mathematics.” He graduated with the degree of Bachelor of Science in civil engineering, with highest honors, in 1924. Up to that year, he had the best record in civil engineering course in the college.

Alejandro Melchor

We Named Our Company After Him

The following school year, he was appointed instructor in the mathematics in the college of liberal arts. However, in June 1925, he was transferred to the college of engineering as instructor in civil engineering. Two years later he was promoted to assistant professor in civil engineering; and in 1930 he became the secretary of the college. He taught technical mechanics, strength of materials, surveying, theory of structures, design, and foundations. He stayed in the college up to 1936 continued on page 2

efined as the basic physical and organizational structures and facilities needed for the operation of a society, infrastructures play a vital role to a country’s economic development and prosperity. These include transportation, communication, drainage, sewerage, water supply, and electrical systems.

The Philippines is located near the Pacific Ring of Fire, a pathway of typhoons. Due to its geographic location, typhoons often traverse the Philippine Area of Responsibility. With this in line, the Philippines is considered as one of the countries worldwide most exposed to seismic hazards and to the effects of climate change. Thus, maintaining infrastructures in the Philippines is a major concern for the Philippine government as these systems are prone to natural disasters.

AMH Philippines Inc. has long been involved in aiding the Philippine government through hazard mitigation and risk reduction of existing and new infrastructures respectively. Some of the projects of AMH include the South Luzon Expressway (SLEx) – Daang Hari Link Road and the Subic-Clark-Tarlac Expressway (SCTEx) Project.

The SLEx – Daang Hari Link Road was constructed in 2012, connecting Bacoor, Cavite to the South Luzon Expressway thru Susana Heights. The link road will pass through the New Bilibid Prison Property, which is intended to be redeveloped into a mixed commercial, residential and institutional estate. AMH, as an engineering consultancy firm, provided geotechnical consultancy services: Design Optimization and Value Engineering of the retaining wall systems and Slope Protection for the link road.

West Valley Fault

P

HILVOLCS, led by its director Renato Solidum, has unceasingly warned Filipinos of the next big quake in Metro Manila. “It can happen within our generation or the next generation,” Solidum says.

The “next big one” is expected to occur along the West Valley Fault; a crust fracture line that runs from the heights of Sierra Madre down to Laguna. The fault runs across parts of Metro Manila (Quezon City, Marikina, Pasig, Makati, Taguig, and Muntinlupa). The fault has moved four times in the past 1,400 years. On average, it moves every 400 years, “+/- 10 to 100 years, maybe”, Solidum says. The last time an earthquake occurred along the West Valley fault was in 1658, around 355 years ago. Simple Math would tell us that the fault is just 45 years away from reaching its movement cycle of 400 years.

The recent April 2015 Nepal earthquake has a predicted 750 year movement cycle and was reported to move last 1344; the earthquake occurred 79 years earlier than expected.

“Let us learn from what happened in Nepal. We all need to act now,” Solidum said in a slideshow presentation at the Carlos P. Romulo Foundation’s Earthquake Resilience Conference held last May 20 where he discussed April’s earthquake in Nepal and the anticipated Metro Manila quake.

In 2011, AMH participated in the Landslide Hazard Assessment and Mitigation for the constructed Subic-Clark-Tarlac Expressway.

Engineering assessment of slopes along the expressway were conducted and earth retaining structures were designed. AMH was once again called upon by the Manila North Tollways Corporation (MNTC) in 2012 to conduct a reassessment and update of the slopes, providing appropriate mitigating measures to address critical and high risk areas. 

by Author Name The West Valley Fault is expected to generate a 7.2 magnitude earthquake. Magnitude is the amount of seismic energy released by an earthquake. On the other hand, Intensity is variable over the area affected by the earthquake, with high intensities near the epicenter and usually lower values further away. The April 2015 Nepal earthquake has a magnitude of 7.8.

The Metro Manila Earthquake Impact Reduction Study (MMEIRS) by JICA, MMDA, and PHIVOLCS reported that the West Valley Fault earthquake may cause fatal casualties up to 33,500 due to building damages alone. It is expected that up to 12.7% of residential buildings, 10% of 10-30 storey buildings, and 2% of 30-60 storey buildings will be heavily damaged. Based from these data, residential, and medium to high rise structures are most vulnerable. In addition to damage caused by ground movement, tsunami, fire, landslide, liquefaction, and other hazards should also be considered.

The warning by PHIVOLCS and the findings of the MMEIRS enables us to see the risk ahead and prepare for it. Earthquake damage mitigation efforts are currently being spearheaded by PHIVOLCS and NDRRMC on the national level. On a macro scale, emergency preparedness

The Science of Retrofitting

he recent study by PHIVOLCS on the West Valley Fault System prompted residents of Metro Manila to conduct structural audit and geological testing of the buildings stretched along earthquake-prone areas. To ensure the structural integrity of buildings and to mitigate the risks being posed by the West Valley Fault, structures, which are identified to be inadequate by the National Structural Code of the Philippines 2010, are recommended to undergo the retrofitting process.

To shed light on the matter, retrofitting, in layman’s terms, is modifying something after it has been manufactured to continually sustain its primary purpose. Structural retrofitting, as the name suggests, is the modification of existing structures to guarantee the functional continuity of their life line and to ensure the utmost safety of the occupants, as it aims to reduce the loss of lives through damage of facilities.

Seismic retrofitting, a form of structural retrofitting, reduces the vulnerability of damage of an existing structure during an application of external force, i.e. earthquakes. It is aimed to strengthen structures with insufficient seismic resistance to satisfy the requirements of the current codes for seismic design.

Noted to account for a major portion of the total cost of hazard mitigation, this kind of retrofitting is beyond conventional repair or even rehabilitation, as it reinforces structures to withstand and, ultimately, to prevent collapse in the midst of a severe earthquake. As a nation situated in the Circum-Pacific Belt, also known as the Pacific Ring of Fire, there is a need to periodically reassess our structures for earthquake resistance, as new structural and seismic codes are developed from time to time.

programs and hazard maps are currently being developed for public safety.

Risk mitigation even at the micro level, require an understanding of the hazard, exposure and vulnerability of our structures. It is prudent to consult with insurance companies for economic security and engineering consultants for structural and geotechnical risk analysis and mitigation.

The well-known statement “Earthquakes don’t kill people, buildings do” highlights the need to make not just our structures, but also our communities more earthquake resilient.  References: 1. http://www.gns.cri.nz/Home/Learning/Science-Topics/ Earthquakes 2. http://www.abs-cbnnews.com/nation/metro-manila/05/15/15/ phivolcs-west-valley-fault-ripe-strong-quake 3. http://earthquake.usgs.gov/research 4. http://www.philstar.com/headlines/2015/06/15/1466175/whatwe-need-know-about-valley-fault-system 5. http://www.gmanetwork.com/news/story/316877/scitech/ science/the-next-big-quake-in-metro-manila-may-hit-within-ourlifetime 6. http://ndrrmc.gov.ph/attachments/article/1472/Earthquake_ Impact_Reduction_Study_Volume_1.PDF

Column and beam jacketing may also be applied to all members of the structure to increase its global capacity. A more costeffective approach is by increasing the local capacities of some members. It involves retrofitting, e.g. jacketing, of only selected members of the structure.

Another seismic retrofitting technique is base isolation.

This technique involves inserting flexible isolation systems between the foundation and the superstructure. These systems reflect and absorb some of the seismic energy before it gets transmitted to the superstructure. This innovative retrofitting technique not only prevents a structure from collapse but it also reduces damage, which is vital for facilities that are expected to remain operational after earthquakes.

Installation of dampers may also protect structures from collapse, as dampers absorb shock, dissipate energy throughout the building, and reduce the displacement and acceleration demand within the structures.

Structural and seismic retrofitting may be applied to different types of buildings, industrial structures, bridges, urban transport structures, marine structures and earth retaining structures. Also, retrofitting measures may be used in the conservation of historical landmarks, as these are integral parts of our heritage.

As part of AMH’s commitment to provide excellent service to the Filipino people, it has invested itself in providing retrofitting measures for structures across Metro Manila.

To name a few, two of AMH’s retrofitting projects are the complete rehabilitation of a heritage site, the Manila Army Navy Club, and the seismic retrofitting of buildings located in the National Grid Corporation of the Philippines Complex, where two of the three structures were designed by the world-renowned National Artist for Architecture Leandro Locsin. It is also involved in the rehabilitation of structures in Miriam College and Saint Pedro Poveda College.  References: 1. http://nidm.gov.in/idmc2/pdf/abstracts/eq-a3.pdf 2. http://web.mit.edu/liss/archive/IST_documents/earthquake/ Part5.pdf 3. https://www.melbourne.vic.gov.au/1200buildings/what/Pages/ WhatIsRetrofit.aspx

MH continued its internship program that exposes newly graduates to various civil engineering projects and to several senior and design engineering mentors. This year, the interns are rotated every quarter to the four different practice-based groups namely Structural Engineering Group, Civil Works Group, Water Resources Group and Geotechnical Engineering Group in which AMH adopted in year 2014.

A new batch of interns was accepted this January 2015 after passing the Civil Engineering Licensure Examination held in December 2014. This batch consists of seven (7) UP Alumni and three (3) UST Alumni. Two of them were Magna Cum Laude graduates (Gabriel S. Miro and Laurenz Luigi Cruz). Also, it was Luigi who ranked 9th in their Civil Engineering Licensure Examination.

Boot Camp. AMH warmly welcomed the Batch 2015 CE interns through a “Boot camp”. In the military, boot camp refers to the training program for new recruits.

This boot camp served as a venue for the different practice-based groups to introduce the various fields in civil engineering as well as to get to know each of the interns. The interns found the boot camp as a great start of their career in AMH.

Ever since the beginning of the internship program, the interns got already exposed Having been part of the company for to various projects in AMH. They were more than half a year, the interns stated given the opportunity to learn the that truly they are proud of AMH. It different softwares used in each field of is because they saw a company that civil engineering. Aside from the fields upholds honor and integrity, a company of civil engineering, some of the interns that values each and every one of its were also immersed in disciplines such employees and a company that aims as geology and geophysics. According to to give its best to provide engineering the interns, the internship program is solutions that the country needs. 

Brownbag Session. During Mondays, the interns attend a brownbag session from 4:00 PM to 5:00 PM. The main objectives of these sessions is to give the interns the opportunity to communicate, to air concerns and to share their experiences from the different projects they get involved in. However, these sessions does not only consist of non-technical discussions but technical discussions as well. Due to the recent news about the West Valley Fault, there was once a

2015 PICE National Midyear Convention by Author Name

s part of AMH’s continuous development of its practices as well as of its employees, involvement in engineering conventions has been part of the company’s important commitments. For the past several years, AMH has presented technical papers in events held by the Philippine Institute of Civil Engineers (PICE), the country’s most established civil engineering professional organization. In this year’s PICE National Midyear Convention, two papers about the recent practices in geotechnical engineering in the Philippines were presented

by AMH in response to the theme: Filipino Civil Engineers: Ready for Global Practice. Engr. Erickson Delos Santos made a presentation about the study: “Design Considerations for Soil-Nailed Walls and Slopes” while Engr. Ramil Diaz presented the paper entitled: “Design Approaches for New Airport Pavement and Overlay.” The convention was held at the SMX Davao Convention Center SM Premier Lanang last May 28-30, 2015. 

Design Considerations for Soil-Nailed Walls and Slopes

Abstract: The utilization of soil nails can be a costeffective solution to stabilize cut slopes or gradeseparated roads and highways. This involves a passive steel reinforcement encased in grout and a shotcrete or concrete cover applied on the slope or excavation face to provide continuity. In the absence of local codes and specifications governing the design and construction of soil nails, the provisions of US Federal Highways Administration (FHWA) can be adopted. This paper presents the various considerations in the stability analysis and design of soil-nailed walls and slopes.

AMH Engineers Erickson Delos Santos, Gian Reyes, and Ramil Diaz at the PICE 2015 National Midyear Convention in Davao Design Approaches for New Airport Pavement and Overlay

Abstract: With the development of new airports and re-development and expansion of existing airports in the country, the adequacy and durability of airport pavement and overlay is a primary concern for civil engineers, pavement design engineers and contractors. Following international standards, the guidelines and procedures developed by the Federal Aviation Authority (FAA) and U.S. Army Corps of Engineers (USACE) for designs serving new construction and rehabilitation of airport pavements are adopted. This paper presents the (1) different design approaches for new and overlay design of both rigid and flexible airport pavement using engineering design tools such as FAA Rigid and Flexible Iterative Elastic Layered Design (FAARFILED) and USACE’s Pavement-Transport Computer Assisted Structural Engineering (PCASE); and (2) various non-destructive tests for soil investigation.

What is PLAXIS?

An opportunity to learn

Plaxis is a finite element modeling software capable of two and threedimensional analysis of deformation and stability for various problems in geotechnical engineering. Plaxis is also capable of creating complex soil and structure interactive models and can constitute nonlinear strength, time dependent and anisotropic behaviors of soils and rocks. It provides more thorough analysis and investigation of the problem using 2D and 3D Finite Element Method analysis with more refined soil model.

It is, without a doubt, evident that Plaxis is at the forefront on the numerical methods in solving geotechnical engineering problems.

As such, the staff of the geotechnical engineering team of AMH did not hesitate to consult with Dr. Chaeng on how to further optimize the use of the Finite Element Software. The discussion involved the application of Plaxis on several projects previously and currently undertaken by AMH. Dr. Chaeng discussed several methods to further improve the accuracy of the

resulting models and he also made recommendations on how to approach the modelling of future projects. The discussion was definitely a grand opportunity to learn, not just about Plaxis, but also the fundamentals of Geotechnical Engineering.

AMH and PLAXIS

”

Since 2013, AMH Philippines Inc. has been using Plaxis as tool for several Geotechnical Engineering analysis.

Plaxis has been used in a number of different projects involving slope stability analysis and excavation protection design. And last July 1, 2015, AMH in cooperation with Plaxis Asia-Pacific decided to take it a step

further by providing a free seminar to introduce Plaxis and its capabilities to the representatives of the top engineering companies in the country. Dr. Wiliam Chaeng, from Plaxis Asia Pacific, discussed a wide range of topics from the capabilities of Plaxis to its application on the field of geotechnical engineering. Dr. Chaeng also presented several projects where Plaxis was utilized to solve several geotechnical problems including excavation protection, tunneling and slope protection.

“

AMH breaks through standard geotechnical processes in the country.

”

Plaxis is perhaps one of the most essential tools for a geotechnical engineer given its wide variety of used and applications.

However, it must always be noted that Plaxis can never be a substitute to the experience of a geotechnical engineer can acquired upon years of practice. It must always be remembered that no matter how sophisticated the model is, it will always be dependent on the parameters that the user will input in the program.

It must always be ensured that proper field and laboratory testing procedures are observed, and parameters acquired from the test results and correlations must have sound basis. Plaxis will never be a substitute for a good geotechnical practice, but will only make a good geotechnical practice even better. This where experience always counts. 

MESSAGE FROM THE PRESIDENT A

MH enters its 16th year with the ASEAN integration and a growing Philippine economy at the backdrop. With massive transport infrastructure, energy and property development, comes the challenge of mitigating hazards, and managing and reducing risks, in the light of various natural hazards the Philippines are constantly exposed to.

ASEAN Integration presents an opportunity and a challenge. It envisions a competitive economic region that is integrated in the global economy, aimed at equitable economic development.

Inward looking, the challenge for us at AMH is to achieve consistent and sustainable growth – by continuously improving and strengthening existing business in one hand, and by strategically pursuing new opportunities in the other.

Expanding our horizons is therefore the call of the times - expanding our capacity, expanding our capability, expanding our market, expanding our planning horizon, expanding our perspective. An expansion in breadth and depth.

This issue of Engineering Times capture our ongoing response to this call. Our successful ISO Quality Management System (QMS) certification, institutionalized Internship Program, continuing active participation in PICE (Philippine Institute of Civil Engineers) and the CECOPHIL (Council of Engineering Consultants of the Philippines), learning new technologies and tools, trainings and short courses here and abroad, our take on the West Valley Fault and VFS Atlas, our contribution in public-private infrastructure projects, and our view of ASEAN Integration --- while constantly reminding ourselves of who we are and what we are about; looking up to our model and inspiration - Alejandro Melchor – world-class engineer, educator and patriot.

Let’s sail on, Team AMH. The seas may sometimes be rough. But with God’s guidance and protection, let’s have the courage and confidence to take new and uncharted waters. To paraphrase John Shedd, ‘A ship is safe in the harbor, but that is not what ships are built for.’
