THE IMPORTANCE OF DISPUTE BOARDS IN A PROJECT

Did you ever heard about Dispute Board?

Dispute Board is a party who will manage the dispute or lead each parties in the projects to avoid a dispute during the project execution. Dispute board can be divided become standing Dispute Board or a Dispute Board which hired after or during dispute happening in the project.

Dispute Board is one of the important party in a project especially in the international project. As we know in the international project, barrier language could be a big possible dispute in the future. Each peoples has their own mindset and their own understanding for each case. That is why, it will be more wise if during the planning, execution and closing the projects, Contractor, Consultant and the Employer hired a Dispute Board Party to secure them from any dispute in the future.

Dispute Board member should be independent and doesn't has any interest for a project party. During their contribution, Dispute Board will giving their analysis or advice about the projects in order to keep each parties from any disputes which is not good for the future of project and business development. Probably, several people will think Dispute Board is wasting money, but if you see in the bigger level, avoiding the dispute can be a win win solution for each interested parties in the projects.

Later I will deeply talk about this topic.

See you in my next post.

COMPARISON BETWEEN QUALITY ASSURANCE AND QUALITY CONTROL

Aloha my blog readers!!!

Thanks again to subscribe my blog and you can subscribe my YouTube Channel : YELNA YURISTIARY too for gain several information about me and Civil Engineering.

In this post I would like to share to you 6 comparison between Quality Assurance and Quality Control.

1. QA : a managing tool, QC : a corrective tool
So QA is one of a managing tool for maintain the quality of products. QA is a system built by the company to manage their quality and will be corrected by QC.

2. QA : process-oriented, QC : product-oriented
QA contains of several process to achieve a quality goal. In other hand, QC is more product oriented.

3. QA : proactive strategy, QC : reactive strategy
QA is a proactive strategy for reduce the defects and QC is more alike reactive strategy to detect the defects. So if we apply a good QA, there's a chance we will get less defects.

4. QA : prevention of defects, QC : detection of defects

5. QA : everyone's responsibility, QC : testing team's responsibility
To applied QA, all of stakeholders need to put their own effort. For QC, the result will be depend on how the teasting team doing a test.

6. QA : performed in parallel with a project, QC : performed after the final product is ready
QA will perform from the beginning the project till the project finish. QC is a part of checking the quality of project after the products finish.

Perbedaan Nilai Index of Continuity dan Drop Test pada Block Integrity Armour Stone

Hai teman-teman semua...

Pada postingan ini aku mau cerita tentang sedikit perbedaan antara Index of Continuity dan Nilai Drop Test pada Armour Stone. Oke jadi untuk istilah-istilah yang berbahasa Inggris disini aku jelaskan secara tidak langsung saja ya.

Oke, jadi Block Integrity itu lebih kepada ketahanan dari armour block dari crack ketika armour stone atau armour block ini dijatuhkan. Maksudnya disini begini, jadi kan dalam pembangunan breakwater atau bangunan coastal lainnya itu ketahanan dari armour stone atau kalau bahasa Indonesia-nya itu batu-batu gede yang ada di tepi laut itu kan sangat penting. Secara nantinya batu-batu itu akan terhempas gelombang air laut yang biasanya itu sangat besar. Jadi perlu adanya ketahanan dari batu-batu yang besar itu. Nah untuk penilaiannya di internasional itu istilahnya dikenal dengan nama Block Integrity.

Untuk menilai Block Integrity itu umumnya orang-orang memakai test drop atau test dimana batu itu dijatuhkan dari ketinggian 3 m ke bawah dan disambut oleh batu-batu lainnya. Nah, pada test drop ini biasanya akan diketahui nilainya tuh. Adapun peraturan internasionalnya itu biasanya mengikuti aturan dari CIRIA SP83.

Namun, di tahun 1989, LCPC itu mengeluarkan test report yang menyatakan bahwa sebenarnya Block Integrity itu juga bisa dilihat dari nilai Index of Continuity-nya. Jadi itu pengambilan value dari Index of Continuity lebih berdasarkan kecepatan suara/sonic velocity. Jadi itu testnya lebih menggunakan alat, dimana alat itu bisa mendeteksi crack yang ada di dalam stone itu sendiri. Nah untuk Index of Continuity itu biasanya nilainya semakin besar akan semakin baik. Untuk nilai ini, biasanya peraturan internasional akan mengacu kepada EN Standard 13383.

Tetapi, dalam pemakaian nilai drop test dan Index of Continuity ini sebenarnya ada kelebihan dan kekurangannya masing-masing. Jadi kedua test ini dapat digunakan berbarengan untuk mendapatkan hasil yang maksimal. Hanya saja, nilai Index of Continuity ini tidak terlalu relevant karena crack pada stone itu bisa saja terjadi beberapa hari setelah waktu blast dari armour stone ini. Jadi crack bisa saja terjadi setelah si batu ini diletakkan/disusun di tepi pantai karena crack bisa dipengaruhi oleh water saturation dari air laut itu sendiri.

Nah, Manual Rock yang biasanya dipakai oleh engineer nih, merekomendasikan untuk kita menggunakan test drop untuk melihat Block Integrity dari Armour Stone kita.

LIST OF JOBS FOR CIVIL ENGINEERING STUDENTS

Hi all my log readers...
Maybe you remember last time I post about my Kaizen activities target.
Believe me, it's quite bit hard to follow that one for me. At early stage I'm feeling so excited to start. But that feeling was faded slowly and left behind. Now, again I saw myself and I feel a little bit guilty because already made a bad commitment to do some KaiZen activities.

As a human, I again want to try. At least I still have hope to be better daily. ^_^

Okay. In this post I would like to share about what kind of jobs, the Civil Engineering students can get after they finished their study.

1. Work in Construction Sector
This is sure. All of Civil Engineer student can work in construction sector. You can be Employer, Engineer or Contractor in every side of Construction sector. Depend on your path, where you will go. If you joined in contractor sector, you will see the field more than Employer can see. I mean, in your daily life might be you will face several problem which it can develop yourself to be more experience in construction field. If you become Engineer, or sometimes we called as consultant group, you can learn more and sometimes you need to be advance in design. You should know more and more. There's no time for saying I don't know because consultant is like a bridge between Employer and Contractor.

2. Being Analyst at Bank
If you like to study about investment analysist in your college before, maybe you will be a good member for an analyst in the bank or some investment office. I mean you will decide how big the effect of your money to a project. This is not only construction project. You can decide which bussiness will being good based on your investment analysist and financial analysist.

3. Being Investment Analyst for Property Sector
These kind of job is almost same like being analyst at bank. Being an investment analyst for property company made you can decide which step that company need to take for gaining more profit. It is all based on the ROR or MARR you can choose.

4. Work in Manufacture Company
If you have a big interest in Project Management or Quality, maybe working in manufacture company is not a big issues for you. Work in manufacture has a little bit difference with work in project site. In manufacture, mostly you need to apply Value Engineering to increase your optimize your Life Cycle. In project, you need to solve the problem which is more not typical from one to anothers.

5. Work in Oil and Gas Company
In Oil and Gas Company, they need Civil Engineer also as their facility and maintenance people. They need structural engineer too for help them to design their platform. All of their platform need Structural Designer to making sure their operation will not failed in the middle.

6. Open your Own Bussiness
This is all people can do is, STARTING YOUR OWN BUSSINESS. Being a Civil Engineer will help you to manage everything better because you will have the good logical thinking based on the practical phase.

7. Work in Hotel
In hotel, they need Facility Engineer to making your all of building systems working well.

8. Become A Lecturer
If you are the person who likely to share to others, you can be a lecturer. You can teach the next Civil Engineer.

9. Become A Tutor for Some Skilled Courses
This is same like in point 8.

10. Work in Airport
You can work in airport as engineer. You can make schedule for the flight or do some engineer's work there.

11. Work in Marine Company

Financial Investment Analysis in Conceptual Design Kali Besar Restoration Project Based on Benchmarking Process in Cheonggyecheon Restoration Project


Abstract Research Plan

Jakarta is the capital city of Indonesia which is located in the northern Java. Jakarta is divided into five sections and has a population about 10 million people. The city is the most popular in Indonesia and has the rate of growth of urbanization. The history of the city began with the small city, called Batavia or Jayakarta. The old city (Batavia) is located in the north of Jakarta as a center of Dutch Colonial in pre-independence time. In this region there is a river that has the function as center of city and transportation hub of human activity. However, because of the population growth in Jakarta and urbanization increasing of the city, this area is becoming congested and polluted.
 
The biggest problems facing Jakarta besides flooding and congestion is pollution of water bodies. From 13 rivers in Jakarta, there is no one worthy as raw water source. One of rivers that no longer have a function as a body of water and raw water provider is Kali Besar. Long times ago, this river used to be inland waterways in Jakarta. But, it change after people evolve urbanization paradigm.
 
On the other hand, the government has a plan to improve the city and reduce pollution. One of the chosen path is the restoration of Kali Besar River which is the source of the city's history. Lack of budget funds make the implementation of this project stunted and not optimal. Based on these problems, the authors find solutions to attract investors to finance construction work in that project. Investment feasibility analysis will be carried out in Kali Besar restoration project. Value of the investment feasibility analysis will be obtained by using the method Life Cycle Cost, Net Present Value (NPV) and Internal Rate of Return (IRR).
 
Feasibility analysis research done by applying a comparative study between Kali Besar Restoration Project (Jakarta) and Cheonggyecheon Restoration (Korea). Author choose Cheonggyecheon as benchmarking project because it has function and problem identic with Jakarta.

Special Purpose

Looking at the problem from Jakarta City and its development, this research has a spesific purpose:
a.       Knowing the investment analysis of river restoration project in Conceptual Design River Kali Besar Restoration program (with methods IRR and NPV value).
b.      Knowing Cheonggyecheon River Restoration History as a best benchmarking which applied the same project.

Importance of Research Planned

This research is very important because it gives solution in Indonesia and some other countries are experiencing the same problem (water polluted). Most developing countries are still have major problems such as environmental pollution and city planning. This research is important to provide a solution and settlement overview of the urban planning activities, like a restoration project. River restoration can provide flood protection function (Hwang K. Y., 2004) and measuring the rate of water flow (Park, 2007). River restoration aims to improve the quality and function of rivers and to restore the to support healty and thriving ecosystems. Improved landscapes and views of waterways can increase property values by between 6-8% (TCPA, 2005). Life Cycle Cost Analysis is the important thing to develop investment feasibility to build this project in Indonesia.
