Certains plan de la maison ...



Un plan d'étage est un dessin au trait simple montrant les chambres comme vu de dessus.
      Les murs, les portes et les fenêtres sont souvent à l'échelle.
      Lorsque vous magasinez pour les plans de maison ou des plans de construction, vous pouvez étudier  les plans d'étage pour voir comment les chambres sont disposées. 
      Cependant, un plan d'étage est pas un plan ou un plan de construction.
      Pour construire une maison, vous avez besoin d’un ensemble complet de plans de 
construction qui comprendra des plans d’étage, des dessins en coupe, les plans électriques , 
des dessins d'élévation , et de nombreux autres types de diagrammes .





Construction of the railway bridge line 2 of the Santo Domingo Metro

The Office for the Reorganization of Transport (Opret), in the Dominican Republic, announced that metro Line 2 construction work is nearing completion and network testing is expected to begin within the next 6 months. Santo Domingo operator OPRET awarded Alstom Transport a contract for the design, manufacture and putting into service of 15 Metropolis train sets for its second metro line. This contract completes the previous one, for the supply of 19 Metropolis train sets for Line 1.

Opret deputy director Leonel Carrasco said that a tunnel, which has been constructed as part of the works, has been a particularly complicated undertaking, has now been fully constructed. Focus is now turning to complete the electromechanical phases, installing rail and electrification equipment.
The bridge across the Ozama river, linking the capitals administrative district with the eastern zone, is now 60% complete.
The line will be operated by six trains, each with three cars. The route has four new stations which are currently under construction.
    

           

Some idea vs tier

Congratulations, engineering graduates! By completing this degree, you are becoming part of a very special group: you are becoming engineers. I want to share my own path to engineering; discuss what makes engineering a unique and noble profession; explain your roles and responsibilities as an engineer in our society; and give you some advice for success based on my own experiences.
I grew up as one of four children in a family of engineers and mathematicians. My parents would leave science and math and engineering textbooks around the house; they figured that if they exposed each of us to science, technology, engineering, and mathematics enough times, eventually something would take hold. My father inspired by example; I often saw him sitting at the kitchen table, late at night, working on engineering problems. I didn't completely understand what he was doing, but I figured that it must be something fascinating and important to keep him up that late. It also made an impression on me because he seemed so happy and peaceful when he was doing his engineering work. So I figured that if I worked hard, maybe I could find that kind of happiness one day too. My mother, as a teacher, was more direct and explicit in her methods for inspiring others. When I was applying to college, she said, “You can be anything you want to be. You can be any kind of ENGINEER you want to be.”
Engineering as a profession is open to anyone and everyone, regardless of gender, race, family background, or social status, which is part of what makes it special. You don't have to look a certain way to be an engineer. In fact, engineering benefits from having a diverse group of innovators, because only by bringing diverse perspectives can we invent and innovate for a diverse society. But engineering is also meaningful for deeper reasons. Engineers carry a sense of wonder for the world around them. We as engineers look out into the world, and we can see that everything has an underlying mathematical and mechanistic basis. We recognize that we can understand and model our world, using the tools of quantitative analysis. We see the connections and the exchanges between science and engineering, how advances in science lead to advances in engineering, and vice versa.
Most importantly, we as engineers realize that we have the ability to solve pressing world problems in energy, sustainability, transportation, education, healthcare, food, and the environment. While other disciplines in basic science aim to understand reality, engineers ultimately seek to build a new reality, a better place for everyone. When I pursued my education in biomedical engineering, and worked in the hospitals and clinics, I saw engineering everywhere. Engineering was needed for manufacturing the pharmaceuticals, designing the intravenous infusion pumps, programming the electronic medical records. I found that biomedical engineers were as much a part of patient care as nurses and physicians. Similarly, mechanical engineers and civil engineers contribute to transportation; environmental engineers contribute to sustainability and energy; and electrical engineers contribute to communications.
As engineers, we all want to help people. In fact, it is our duty to serve the public and address global grand challenges; to respect one another and work collaboratively; and to do our best to help others using our skills. Engineers can participate not only in making life better and more comfortable for everyone, but also in saving lives. My advice to you, as young and emerging engineers, is to always remember why you entered this profession in the first place. Always remember that your goal is to use your skills for the betterment of society. Importantly, always remember the sense of wonder and creativity that drives your interest in engineering.
I also advise you to be courageous and resilient, because engineers are needed now more than ever to solve difficult problems in the world. This field is for the brave, not for the faint of heart. This field is for those who are willing to stand up for what is right, not for those who just crave comfort and security. This field is also for the kind and caring souls, not for those who are cold or unfeeling, because engineering is at its core about humanity. I wish I could make sure that you always have a cheering section. But I cannot. What I can tell you is this: if you pursue your career as an engineer with dedication, with honesty, with commitment, with conscientiousness, and with love, then you can always be proud of yourself. You can look in the mirror and be your own cheering section. This is the definition of resilience. This is courageousness. This is character. This is what it means to be an ENGINEER.
There is one other ingredient though, and I want to end on this note. Engineering means being collegial. I saw a great movie recently called "My Own Private Idaho." One of the characters in the movie has narcolepsy, which means he falls asleep throughout the day, and he can't control it. In the final scene of the movie, we see this character passed out by the side of the road. A car pulls up, two men get out, and they steal the young man's shoes and his money, and leave him on the side of the road. A minute later, another car pulls up, a man gets out, and he lifts up the young man and helps him into his car. And life is sort of like that. When you're by the side of the road, some people are going to steal your shoes and steal your money and leave you there… and other people will lift you up and give you a ride. So when you think about yourself, and how you want to function in the world as an engineer, my advice is that you want to be the person that lifts other people up. It is your duty as an engineer, it will make you feel better about yourself, and it's just plain the right thing to do.
Congratulations to all of you, engineering graduates. Never forget why you entered this profession, and never forget who you are. I stand in awe of you and your accomplishments, and I look forward to your future contributions to engineering.

Portugal , A 24 highways


Roads in Portugal are defined by National Highway Plan, which describes the existing and planned network of Portuguese roads.
The present plan in force is the 2000 National Highway Plan (PRN 2000), approved in 1998. It has replaced the previous PRN 1985, which itself had replaced the PRN 1945.
The Portuguese road infrastructure is considered the best in Europe and the second best in the World by the  World Economic Forum in its Global Competitivenes
