This video discusses the potential applications and implications of pre-fabricated concrete construction in the context of Covid-19. The presenter argues that pre-fabricated concrete construction is more economical and quicker than traditional construction methods, and that it can be adapted to meet the needs of health emergencies. The video goes on to discuss the benefits of standardization and how it can help speed up construction and reduce costs.

  • 00:00:00 In this video, a seminar is held to discuss concrete pre-fabricated applications and possibilities in the context of Covid-19. The participants discuss rumors circulating in Peru, and the truth. They then share their surprise and excitement when they work together and surprise each other again and continue to build on what was once such a great foundation. The engineer says that together, we can achieve anything. The seminar concludes with a discussion of how to work together to achieve development goals.
  • 00:05:00 This video discusses concrete pre-fabricated applications and possibilities in the context of Covid-19, the healthcare crisis day today. Engineer Juan Carlos Paucar presents engineer Henry Leon, who will present the topic of concrete prefabricated construction applications and possibilities. The videos for the 15th week of virtual seminars organized by the Civil Engineering Chapter of the Lima Council of Engineers were presented by Engineer Christian. This week's topic is concrete prefabricated construction applications and possibilities in the wake of Covid-19. Juan Carlos Paucar, Engineer Christian's colleague, introduces Engineer Henry Leon, who will present concrete prefabricated construction applications and possibilities. Leon has more than 18 years of experience in professional engineering and is currently the Head of Technical Dance Office of a Spanish company in Peru, as well as a professor at the Pontifical Catholic University of Peru. He has also been a professor at the University of the Pacific. This week's seminar is entitled "Regulation of Contracts in the State of Peru." There are also five other seminars this week covering topics such as infrastructure, hospital construction, hydraulic engineering, construction process design, and bridge construction. In previous weeks, 44 conference sessions have been arranged covering a variety of topics such as model structural engineering, applications
  • 00:10:00 The speaker discusses the importance of pre-fabricated concrete applications and possibilities in the context of Covid-19, and how the system can be adapted to new times. In addition, the speaker discusses how this system, which is used in many other countries, can be adapted to meet health emergencies. First, the speaker shows how the design stage is related to the manufacturing and transport stages, and then shows how the structures are manufactured in conditions different from those in a typical construction site--in a factory. Next, the speaker discusses how learning from previous projects is important in the next years, as is adapting the protocols used in concrete pre-fabrication. The speaker also discusses the impact on industry of Covid-19, and how it will affect the design and construction of pre-fabricated concrete.
  • 00:15:00 The speaker provides a brief overview of the benefits of using pre-fabricated concrete construction, and discusses ways to reduce the time it takes to construct a project. He also discusses the issue of standardization, and how it can help speed up construction and reduce costs.
  • 00:20:00 In this virtual seminar, concrete pre-fabricated applications and possibilities in the context of Covid-19 are discussed. While always being more economical, we strive to minimize time and costs, but we maintain the quantity of concrete we need to empty in order to get paid. Suddenly, we might choose partial or total pre-fabrication solutions, where more elements can be prefabricated at once, thus reducing the amount of emptied areas in construction projects. In this example, a border station between Colombia, Peru, and Argentina is prefabricated concrete construction. The columns, beams, and paving slabs are all pre-fabricated, and this is located in a high mountain area, which also experiences climate changes and snow. Using prefabrication here can reduce the amount of emptied areas that have to be done in construction, which are just these encounters between columns and beams with all the protruding steel you see in the photos. This way, the quantity of concrete that is going to be made here will be smaller even in comparison to concrete, and instead of using grads, we can combine a mortar, tests, and combinations of pre-fabricated and natural stone to reduce the impact of climate changes on this type of construction
  • 00:25:00 Seminario Virtual: Concreto Prefabricado Aplicaciones y posibilidades en el marco post Covid-19 provides a summary of the possible applications and implications of pre-fabricated concrete in the post Covid-19 world. Prefabricated concrete structures can withstand earthquakes, and the report found that they were successful in Chile in 2010. The presenter goes on to say that pre-fabricated concrete is more mature, and has fewer restrictions than codes in the United States.
  • 00:30:00 Chile has its own codes, and they have successfully adapted to pre-fabrication by applying them. This was evidenced by the success of similar experiments done in Italy and Europe. One example is comparing two types of structures- an articulated structure made of pre-fabricated components, and a portico structure in situ. Both were designed under the same principles and subjected to the same acceleration (0.85g). The conclusion of the comparison was that both systems were appropriate, efficient, and dually rigid- one being more so.
  • 00:35:00 The video discusses the similarities and differences between prefabricated concrete and brick-and-mortar construction, and how these structures can be used to improve constructability. There are also talks about how to ensure the durability and monolithic nature of prefabricated concrete structures, and how to design for prefabricated concrete in a similar way to how one would design for brick-and-mortar construction. There are no specific examples given, but the video goes on to mention other questions that relate to prefabrication, such as how prefabricated concrete responds to fire, and how long it will typically last.
  • 00:40:00 In this virtual seminar, I will be discussing concrete pre-fabricated applications and possibilities in the context of Covid-19. Comparing an in-situ knot or monolithic tube between commas and a pre-fabricated knot has yielded similar results, and there has not been a detrimental effect on the disadvantaged due to having more or less joints cold. This can be experimentally tested and demonstrated that it is not an inherent problem with pre-fabrication if a cold question is in-situ or pre-fabricated; either way, it is not well treated. There is a lack of rugosity necessary for pre-fabricated construction to work in any system consultation. Additionally, the Peruvian construction regulation, Chapter Concreto Prefabricado Aplicaciones y Posibilidades, specifies that for pre-fabricated concrete manufactured conditions of plant must be met. Minimum construction coating specifications are different from the coating requirements for in-situ construction even being less stringent. This is due to the fact that pre-fabrication is being fabricated under conditions of plant control, which recognizes that the same standard recognizes that the work environment is very different when working in situ vs. on construction site conditions
  • 00:45:00 The video discusses the use of pre-fabricated concrete applications and possibilities in the context of Covid-19. By purchasing and installing pre-fabricated concrete, the user can work with larger lights and subdivide the beams and slabs, too. This will be disassembled and reassembled in the construction project, encouraging construction. By making the conversion to pre-fabricated construction, developers can reduce the project's overall timeframe. Pre-fabricated concrete is also an economical option to consider for projects of this type. The video shows examples of pre-fabricated concrete structures that are currently in use in Peru, and some that may be suitable for partial customization. By designing structural engineers, one must consider a column's various levels of detail in order to fabricate a single piece. This column will receive beams and important elements in the photo. A horizontal column is being manipulated for testing. It is being made to withstand loading tests before being sent. In a construction drawing, all the information necessary to fabricate the column is transferred to steel cutting tools. The column is then built with a tall front end and connected to an electrical supply. Later, a double-height wall will be constructed using pre-fabricated concrete. These walls
  • 00:50:00 In this seminar video, presenter discusses concrete pre-fabricated applications and possibilities in the context of Covid-19. Prefabricated panels serve as a prefabricated reinforcement without relying on anchors, and are part of this section, composed of a higher compressive layer of concrete, up to 20 cm in thickness. We could not imagine a bulky or suddenly red post-erection, built up over 16 m long, that covers light-sensitive areas, being done in a pre-fabricated way, but this is possible with concrete derived slabs, covering 10 to 16 m with a light load of 500 to 2000 kg/m2, depending on the section, and can be done in a safe range of 10 to 16 m with a heavy load. In addition, we have other applications such as staircases, shown here, prefabricated panels that also have windows, ducts, and doors pre-installed. These panels can have different shapes and functions, depending on their design. Another example is vertical panels used for a industrial shipyard, shown in picture 2. These panels replace traditional closures and are attached to an existing structure, either in- situ, or pre-fabricated. They can also be attached and mounted
  • 00:55:00 This video discusses the potential applications and possibilities for pre-fabricated concrete structures in the context of Covid-19. Pre-fabricated concrete structures are typically 25 or 35 meters long, and can be assembled on-site during construction. The pedestal, which is made out of pre-fabricated beams, is shown in the photo. People are finding various ways to use pre-fabricated bridges, ranging from vehicular bridges to pedestrian crossings. Special requirements must be met in order to use pre-fabricated bridges in extreme locations, such as ducts for removing a beam from its frame. This process does not affect the structural integrity of the bridge. There are also pre-fabricated elements that can be used in stadium construction, such as stands and stairs. Pre-fabricated construction has been shown to be a cost-effective and quicker way to build large infrastructure projects.

This video discusses concrete pre-fabricated applications and possibilities in the context of Covid-19. It is important to have a well-defined geometry in order to use 3D models to determine both the grade levels and the porta-grade beams that will be fabricated, as well as the column sections that can be fabricated. These structures are prefabricated and can be quickly erected in construction. The video discusses the advantages of using pre-fabricated concrete structures, specifically in earthquake-prone areas. It discusses the various ways in which pre-fabricated concrete structures can be customized to meet the needs of the project, and how to verify the construction of such structures in practice.

  • 01:00:00 This video discusses concrete pre-fabricated applications and possibilities in the context of Covid-19. It is important to have a well-defined geometry in order to use 3D models to determine both the grade levels and the porta-grade beams that will be fabricated, as well as the column sections that can be fabricated. These structures are prefabricated and can be quickly erected in construction. We have an example of this project in Leoncio Prado, Peru. Tribunes were built using a pre-fabricated system that allowed for quick connection of the columns to the cementation. In addition, we saw a modular housing project where pre-fabricated modules can be assembled with a system based on limited ductile wall panels. Both systems have been tested and found to be safe. Pre-fabricated concrete has been proven to be seismically resilient and can be used in any country. If we continue to adhere to appropriate design guidelines and ensure resistance and rigidity, pre-fabricated concrete can be used without any problem.
  • 01:05:00 The concrete prefabricated applications and possibilities in the Covid-19 context were discussed in a virtual seminar. The rigid concrete design procedure was not possible to assume without doing an analysis of it, especially in buildings with irregular entries and large empty spaces. We cannot guarantee that a rigid dayfragma is created if we have not done an analysis of how forces travel in that area. The Frank Dayfragma (fragma viennese model) comes in to play as the rigid slab that we will use in this plan. This will impact not only the steel mesh we will use, but also the reinforcement between columns and the empty slab. The part that corresponds to the layer of compression will also require steel connections. Additional steel pieces are needed to guarantee the proper dayfragma behavior in irregular structures, such as beams and columns. All of this is designed step-by-step from the model of a rigid dayfragma that we saw earlier. Many times, this is resolved with finite elements and in Mexico, they have progressed a lot in this field. Regarding formulation hypotheses, for model-ing this dayfragma, more is beyond putting a continuous steel bar below and sticking sticks up. This is more than just a behavior of
  • 01:10:00 Today, the virtual seminar discussed pre-fabricated concrete applications and possibilities in the context of Covid-19. This structure that we call "liberated" is now available and available this zone because we are withdrawing. We continue the installation and come the specialties: Now I'm going to go to the I'm going to advance to the And Conclusions part to see a little of what we've been talking about today. We're not going to finally go away something that gives us the opportunity and we've seen part of the advances today. Find the possibilities of customization talking about what type of projects there are in other countries that we could also start to evaluate and pre-fabricate concrete applications beyond partial prefabrication where there is already a lot of progress with pre-cast panels even there are beams, elements, and slabs being incorporated into the market. This is an example of a building divided into sections in other countries where they have not only urbanistically but also economically has between them spaces. Normally, structures for parking lots are made separate from each other in another land area, what we're looking for is to work in a subterranean way and we've done that. We've made
  • 01:15:00 The video discusses the potential applications and benefits of pre-fabricated concrete building applications in the post-Covid-19 world. Panel systems can be prefabricated in either assembly or a pre-fabricated structure with isolation, which is an educational building at the University of the Andes in Talca, Chile. The columns, beams, and slabs used in the prefabrication process have been made in concrete, and they have been assembled on isolation frames. The cove (a small inlet on the outskirts of Talca), a little more detail: these columns have several levels and are even partially prefabricated, that is, they are made of two or three segments of columns that are assembled in construction and are welded together. In addition, the video shows how the prefabrication of partial or total structures in construction can be faster than building in situ. Some of the key advantages of prefabricated construction over traditional construction include shorter construction times, the use of fewer workers, and the use of new construction design paradigms, such as pre-cast panels. The panel system is a few decades old and has been evolving rapidly, thanks in part to the advances in technology. There are few barriers to
  • 01:20:00 The speaker discusses the potential benefits and drawbacks of using prefabricated concrete structures in different applications. He recommends that engineers take into account the tolerances for assembly when designing a project. He also provides recommendations for plant design in provinces. Finally, he answers a question from Claudia Caga Water about the effect of productivity on prefabricated construction projects.
  • 01:25:00 The speaker gives a description of the effects that pre-fabricated concrete construction can have on productivity, social interactions, and safety. He also mentions a recommendation to account for landscape and construction design in pre-fabricated construction.
  • 01:30:00 The presenter discusses the security risks associated with pre-fabricated construction applications and possibilities in the context of Covid-19. He explains that steel embedded in concrete has its own security risks of foundation calculation. However, beyond that, he discusses what he had been talking about earlier--the ability to anticipate possible failure mechanisms. He then gives an example of a question from the audience. An engineer here, Luis, has a question about how long it would take to apply for pre-fabrication for a construction project, and how long the fabrication process would take. He also asks how long it would take to install the project once it was completed. Pre-fabricated construction can be completed in a short amount of time if done properly. A project that requires a full design and construction cycle would take longer. However, even with a full design and construction cycle, pre-fabricated construction can be completed within four months. And that's just the beginning--pre-fabricated construction can also offer faster response times and reduced construction costs.
  • 01:35:00 One possible application of pre-fabricated concrete is in the construction of highrise structures, such as a 30-meter column, but if there are projects with 60-meter columns, what can be done is to suddenly divide the pieces into 20-meter segments and assemble them. An example shown in Chile uses a building whose columns are about 7 stories high, considering 3-4 meters per floor, but they are 10 stories tall using only 3-4 meters per floor. There are no problems with flexing when the columns are erected, but when the roofing is installed, the beam is designed to be supported only for a certain time until it settles into its final shape. The main limitation in terms of height then becomes the ability of the crane to lift the high column. I would say that, with the current resources, 40-meter columns cannot be built without difficulty, but 60-meter columns can be constructed quite easily, provided the engineer is aware of the potential problems. User asks how a column can be erected without problems of deformation when it is loaded, and Carlos responds that when the columns are pretensadas, the main beam is designed to be supported for a certain time until it settles into its final shape. The cost of a
  • 01:40:00 The video discusses the advantages of using pre-fabricated concrete structures, specifically in earthquake-prone areas. It discusses the various ways in which pre-fabricated concrete structures can be customized to meet the needs of the project, and how to verify the construction of such structures in practice. It also discusses the use of reinforced concrete connections in building structures, and how these can be more easily imitated using special mooring systems.
  • 01:45:00 The presenter discussed the benefits of concrete pre-fabricated applications and possibilities in the context of Covid-19. He mentioned that, while pre-fabricated structures may have similar design requirements, they may also have similar seismic requirements. He then said that, even though pre-fabricated structures may have some advantages over traditional construction, they still need to be designed and analyzed appropriately with the appropriate tools. The presenter also said that, when assembling pre-fabricated structures, it is important to check the connection points for Strength, Vibration, and Fatigue (SVF) compliance. Engineer Juan Carlos Paucar will be taking questions after this presentation.
  • 01:50:00 The speaker thanks the audience for the talk, and later we'll be hiring him to present future exhibitions. He would like to remind the audience of the various courses that they are currently achieving to say to them, "Christian, share the screen with me for the next two weeks." Just as the social restriction was lifted, it will now be difficult to continue with conferences in the evenings. We have been able to secure programming for one course starting on July 6th, which will last the entire workweek from Monday through Friday at 6:00pm. On Monday, July 6th, the topic will be "Enclosed and Masonry Walls for Civil and Building Construction" and the instructor will be Engineer Alex Ruiz Jimenez. Finally, we have one course starting on July 13th and running through July 17th entitled "Metrics 2: Budgeting, Programming, and Valuation in Excel with RWD Systems." This course will be taught by Engineer Walter Ríos and will be held on the same schedule as the previous course, from Monday at 6:00pm to Friday at 6:00pm. We would like to thank everyone for their participation in this virtual seminar and we invite you to sign up for the upcoming courses that we have listed below. We
