as a someone who has experience as an executive of one of the engineering branch of engineering science that studies how to design, build, renovate not only the buildings and infrastructure, but also includes the environment for the benefit of human life.
I have found a case of a building constructed in the site where I work I am. the problem is about crane of tower construction that does not stand firmly or done by a mechanism that is not in accordance with procedures. It is about boom and counter was not balance. Then the cabin will fall if I am let it and not rectified.
So, as a someone who has experience as an executive. I have to prevent this happened. To avoid anything which might be coming. Then I will do :
1. State the Problems :
As an executive engneering this project. I must to check what is the main problem of this situation . How could be the crane will fall? I needs the team of building engineering and cilvil engneriing statement to explain to me about the mistaken construcction be happened. Because, generally the building and civil engineering must know the process of building high-rise buildings ranging from the design stage to implementation stage takes time and careful planning. Including the calculation of the structure is very complicated, too many strict rules from the calculation of the strength of foundation support, the calculation of the size and compositionof thecolumn beam structure, building resistance to static loads, dynamic loads andestimates of earthquake loads that may be facing the building. In the past, the engineers designing earthquake it will resitant about the buildings with a planned major structures(beams, columns) in such a rigid and strong, so as not to shake during an earthquake. It is implemented by designing the structure of columns and beams with large dimensions with dense steel reinforcement which would require a much greater cost and expensive. Given the likely magnitude of the earthquake inertial forces that work in the center of mass of the building, the construction experts argue that it is not economical to plan common structures in such a strong and rigid, so that it behaves elastically when a strong earthquake.
2. Checks the Fact :
The fact that i was got is. Between the boom and enconter site it was not balance. So the top of crane is rather to boom site. The encounter needs some additional weight. Before knowing how to set up a tower crane, it helps us become acquainted with the tower crane. What is a tower crane? And what parts are there in the tower crane? Tower cranes are devices used to transport and move materials and equipment are working hard to reach either vertically or horizontally.
In short, this is how its phases.
1. Planting fine angle and base section into the foundation hole and then to cast.
1. Planting fine angle and base section into the foundation hole and then to cast.
2. Mounting initial mast section using mobile crane.
3. Then the installation of a climbing crane is used to "self assembly"
4.Mounting cabin on the climbing crane. 5. Mounting boom and counter jib6. Counter weight Mounting (load balanced)
1. 2. 3.
4.
5.
After all the parts installed, at the time would raise the height adjusting to the height of the building, the next stage is: 1. Climbing crane will lift the cab up so that there is space between the cabin and the mast section.
3. Process repeated until the height of the TC in accordance with the height that's cool Broadly the stages how Tower Crane can go up and adjust the height of the building
3. The Relevant Facts :
From the the relevant facts i have to find the relation facts about this problem. Not only from the engneering site , but also in management site. Are they buy the material like the engneering order. Or i also have to check about the worker. Are they do the task like engneeriner command? So i have to check all related that can make this happened. And then get the solution to make a decisions.\
4. On the other hands Options that i have to thoght are :
ü Public Safety : accept responsibility in making engineering decisions consistent on safety, health and public welfare, and to disclose promptly factors which might endanger the public or the environment. Engineering field is the field concerning the safety of the people and the environment. For example, a civil engineer who worked to build bridges, should seek to build a bridge as solid as possible for the safety of millions of people who will cross it. The problem is, the safety concept can hinder financial gain or the development of science. This could plunge the engineer to choose to sacrifice safety. “do it safely or do not do it at all”.
ü Ethics in Engineering : Ethics in engineering is a set of standards that specify the obligations of engineers to the public, clients, superiors, and to the profession itself. Ethics to be a guide for an engineer in order to improve the quality of his work, as well as responsible for the safety and welfare of the public. Ethics in engineering is very broad concept. In it, there are points which are techniques to human values which must always be upheld by every engineer.
ü Integrity as an engineering : As someone who has more technical knowledge than anyone else, it's natural for an engineer to accept more responsibility in the work place. Opinion of an engineer is often used as a reference for business decisions, such as selecting suppliers. Therefore, engineers are often faced with circumstances that test their integrity. Not infrequently the supplier offering gifts or other forms of bribery in an engineer with the goal of improving his chances of winning the competition with other suppliers. If this happens, the engineer is obliged to reject all forms of gifts and bribery this. seek, accept, and offer honest criticism of technical jobs, acknowledge and correct errors, and to credit properly the contributions of people to help colleagues and co-workers in their professional development and support them in following this code of conduct.
ü Money and Time : from this case, absolutely i need to fix this problem by additional money and the time. So it might be taken some more money and time from the biginning target. That is why i have to meet any stakeholder to explain to them for kind of each other.
5. Decisions
From all of data from step 1-4 for. It force me to decided that the construction have to be stop for a while and then continued again until the main problems was founded. As soons as possible with the right time and money will using. Or if this problem still can not fix and founded And the still has chance to crane to fallen with any options can not help. We need to rebulit the crane with new team engineering and management are better than before.
