Value Engineering might sound new to most of us but in fact, it could be applied in our daily lives. This concept was best explained to us by Dr. Jerson N. Orejudos, our professor, by taking a pencil as an example. Normally, a pencil consists of a lead, a wooden barrel, an eraser and a metal band supporting the eraser. The ultimate function of a pencil is to make marks. Supposing, we remove the eraser and then, the metal band can also be removed. That would probably reduce the cost of manufacturing pencils by 20% and so it follows that its price could also be reduced. In this way, customers are now given a choice: to buy a pencil with an eraser in a higher price or to buy a pencil without an eraser in a lower price. After all, pencils are made to make marks and not to erase marks.
Why do cost overruns exist in a construction project? Could it be that it carries unnecessary components? By reducing unnecessary items, unnecessary costs are also reduced or eliminated. An item is classified as unnecessary if without it, the whole system functions the same or even better. Value Engineering requires common sense, creativity, innovation, and teamwork. Its implementation improves a construction project by minimizing the life cycle cost and reducing maintenance and operation costs without compromising safety, quality and the environment. While focusing on the basic functions, good or better substitutes are being considered. The best alternative is the one that costs less and performs better. That is why Value Engineering is applied at the design stage of a construction project. The concept is easy but the implementation is so difficult. Value Analysts oftentimes becomes a third party between the owner and the designer. Well, it depends on how we see it. Perception and attitude always counts.
It’s Christmas season once again. As we wait for Santa’s gifts, let us invite Jesus with us. Remember, it’s Jesus’ birthday not Santa’s! I bet Baby Jesus prefers a simple and humble celebration. Since we have our bonuses and 13th month pays, it’s high time to shop and buy gifts for our love ones. Its main purpose is to make them happy. Why not apply value engineering then? Would our grandparents be happy if we give them PSP’s? Would our children be happy if we buy them a golf set? It’s like feeding a cat with colorful M&M chocolates!
Let us just think of the word: FUNCTION. It will then relate to the user’s needs, to an item’s worth, cost and value. For me, this is value beyond analysis. Anything less than the necessary functional capability is unacceptable. Anything more is unnecessary and wasteful.
We always ask God to give us our daily bread, not our bread for tomorrow and the next days to come. Isn’t it that anything that is too much nor too less unfavorable? I may sound absurd but this is just an idea worth sharing. The choice is always yours... Feliz Navidad!

While I'm busy checking papers and preparing for my next lesson, he's also busy sketching, drafting, measuring, estimating. Once he's done, he would always ask for any comment or suggestion. just to shorten his agony i would always say "perfect!".. one thing i've observed, engineering is also a vocation because we cannot patent our design ideas.. mas mabuti pa nga ang quotations kasi may authorship. too bad there is no plagiarism in engineering construction design..
Another thing.. sige nga, tell me how much is the worth of the signature of a licensed CE? degrading? Oh NO! this is the challenge for us engineers.. if only we practice the code of ethics!
Renan and I have sleepless nights together. i do watch movies in the cable TV or in the DVDs while waiting for him to finish editing, changing, printing, and preparing several options for his client. He would always say: THE SUCCESS OF ANY ENGINEERING PROJECT DEPENDS ON THE SATISFACTION OF THE OWNERS. He needs to prepare every small detail of the building very clearly for the carpenters to understand and follow his instructions correctly. According to him, the compensation he gets as a Project Engineer becomes invaluable if the owner couldn't appreciate the outcome of the efforts exerted by the whole team - the carpenters, painters, plumbers, electricians and laborers with the PE as the leader. For them, recognition is more expensive than any amount of money.
From a simple sketch of the floor plan, a masterpiece is done. Renan said: ANYTHING THAT COULD BE DRAWN IN PAPER CAN BE BUILT. how? ONLY A REAL CIVIL ENGINEER KNOWS!
Now that I'm on my way towards the degree in Doctor of Engineering, I still have many questions to ask.
Why I married a Civil Engineer like me? Probably because we complement each other.. Someday, I would understand too why God directed me in this path I'm taking now..
*dad, i learned and i'm still learning a lot from you.. i've helped in making my students become engineers.. and you teach me how to become a true civil engineer by heart..* cholomot.. wabu..

UneXPecteDLy...
let me share with you my schedule:
September 2010
3 - go back to Iligan
4 - @ 9 am - my second reporting in Management
@ 1 pm - submission of Problem Set No. 3
@ 4 pm - attend Professorial Lecture in Environmental Science
5 - @ 1 pm - make-up class in Management
6 - @ 1 pm - presentation of the solutions to the Problem Sets using MATLAB
September 3, i wasn't able to go back to Iligan because Yzabelle was admitted. i felt so worried. all the while i was in the hospital, i was thinking of my requirements and the deadlines. i informed my classmates and my professors and i was so touched with their reactions through texts and phone calls..
GIN, FAMILY FIRST. DO NOT LEAVE YOUR DAUGHTER. EVERYTHING WILL BE OKAY. WE ARE AND WE WILL BE PRAYING FOR YOUR BABY. BE STRONG. COME BACK JUST AS SOON AS YOUR DAUGHTER IS WELL.
September 11, i was welcomed with questions : HOW ARE YOU? HOW'S YOUR BABY? doubled with statements such as: YOU CAN SUBMIT LATER. DON'T WORRY, WE UNDERSTAND. YOUR REASON IS VALID.. even without the doctor's certificate.. it feels so good to be supported by people who barely knew me for three months!

improvised seismograph
Earthquakes generate seismic waves which can be detected with a sensitive instrument called a seismograph. Advances in seismograph technology have increased our understanding of both earthquakes and the Earth itself.
Seismic waves are the vibrations from earthquakes that travel through the Earth and they are recorded. Seismographs record a zigzag trace that shows the varying amplitude of ground oscillations beneath the instrument. Sensitive seismographs, which greatly magnify these ground motions, can detect strong earthquakes from sources anywhere in the world. The time, location and magnitude of an earthquake can be determined from the data recorded by seismograph stations. The sensor part of a seismograph is referred to as the seismometer, the graph capability was added as a later invention.
The goal of a seismograph is to accurately record the motion of the ground during a quake. If you live in a city, you may have noticed that buildings sometimes shake when a big truck or a subway train rolls by. Good seismographs are therefore isolated and connected to bedrock to prevent this sort of "data pollution." The main problem that must be solved in creating a seismograph is that when the ground shakes, so does the instrument. Therefore, most seismographs involve a large mass of some sort. You could make a very simple seismograph by hanging a large weight from a rope over a table. By attaching a pen to the weight and taping a piece of paper to the table so that the pen can draw on the paper, you could record tremors in the Earth's crust (earthquakes). If you used a roll of paper and a motor that slowly pulled the paper across the table, you would be able to record tremors over time. However, it would take a pretty large tremor for you to see anything. In a real seismograph, levers or electronics are used to magnify the signal so that very small tremors are detectable. A big mechanical seismograph may have a weight attached that weighs 1,000 pounds (450 kg) or more, and it drives a set of levers that significantly magnify the pen's motion.
Improvisation makes use of materials available at hand. In making an improvised seismograph, a heavy block of wood was used as a base in which a weight made of steel is attached to a rod using a commercial spring. The weight holds the pen which touches the rolled machine paper. However, movements must be intentionally executed because the paper is attached to a winding motor which needs to be switched on for the paper to unroll.
This improvised seismograph was made not to store any data of an earthquake. It intends only to demonstrate the features and functions of a real one.
Metro Cebu Subway
The Segment 3B – 2 is the subway section of the Cebu South Coastal Road Project as part of the Phase III of the Metro Cebu Development Project (MCDP), headed by Engr. Nilo Pamaylaon of the Department of Public Works and Highways (DPWH) as the Project Director. At present, the DPWH is in the final stages of completing the whole project as it undertakes the last phase of the Segment 3B-2 Subway Section, a first-of-its-kind project in the country being undertaken by one of the most experienced contractors in the world, the Kajima Corporation. It is hopefully expected that its opening will attract investors and will improve the marketability of the 302-hectare South Road Properties (SRP).
The 977 meter Cebu Subway is divided into three sections: the 190 meter U-shape entrance, the 610 meter box tunnel and the 177 meter roadway. A cut and cover method of construction was used. Simple as it may seem but its location, which is at the reclamation area, was taken as a challenge by its contractor, the Kajima Corporation. For tunnels, much like this one, which is close to the seawater, one of the biggest challenges is keeping the water at bay. For this project, contractors had to excavate 30 meters underground and use sheet piles which are 25 meters thick to cut the water because the said project is 20 feet below sea level (Maeda, Kajima Corporation).
The original design was a flyover, but was scrapped because it meant going through the historical site and had met oppositions from environmentalists, tourism and church leaders (Pamaylaon, MCDP III Project Director).
