Technological advancement has brought convenience to the construction industry. It has evolved from hand-drawn drawings to computer drawings in the past, and in recent years has transitioned to building information simulation technology (BIM for short), which allows buildings and their facilities to perform different virtual operations and test them before the project starts. feasibility.
Every technological leap forward, in addition to increasing building efficiency and speeding up the architectural design and construction process, it also enables greater scope and flexibility in creation.
For example, in recent years, the application of BIM has become more and more popular, making it easier to turn into reality the seemingly wild and technically difficult designs. It also allows buildings to maintain more efficient buildings and building services for decades after their completion. Operation and maintenance of full cycle management.

As mentioned above, computer graphics were popularized in the 1980s and 1990s. Although computer graphics lacked the "human touch", it is more efficient to use technology on more complex hospital graphics because it helps to draw different facilities and installations. The plans are easily put together.
The hospital has many wards and operating rooms with different uses. The air-conditioning and ventilation of the building services facilities, fire-fighting sprinkler pipes, water supply and sewage channels, medical gas and other installations are complicated and strict requirements. In the era of hand-drawn drawings One of the most troublesome things for draftsmen or engineers is to integrate different installation drawings into a general plan, and avoid conflicts between the locations of various facilities in order to straighten out the construction.
Because once different devices overlap or collide at the same location or height, the drawings must be changed to avoid obstructing the construction. In the past, different contractors in hospital projects did not properly coordinate the locations of the devices, which blocked the construction. It leads to mutual accusations, and even more to court.

However, with the use of computer graphics, engineers can more easily assemble the puzzles through computer programs, anticipate installation conflicts, and reserve space for maintenance; compared with the old hand-drawn drawings, correct and adjust facilities and installations It takes a lot of manpower and time to modify, and computer applications greatly increase engineering flexibility and efficiency.
The government began to promote the use of BIM technology in the industry several years ago. It stipulated that from 2018, any government capital engineering project budget exceeds 30 million yuan, and the design and construction of the project must use BIM technology.
For the benefits of BIM, many shops focus on its ability to deal with conflicts in the early stage, speed up the construction process and benefits, can more accurately measure and calculate the required building materials during building design, and allow engineers to preview the construction process before construction to reduce errors. It not only reduces the time and delay of the project, but also prevents the project cost from exceeding the budget.
In addition, the extension of BIM technology will also bring stronger facility management efficiency in the full-cycle maintenance period of buildings and facilities in the coming decades.
If there is a problem with a building’s installation, it’s easier for managers to use BIM technology to use three-dimensional graphics to understand where the installation has a problem, and to understand the related problems or which other installations are affected more quickly, so that maintenance is more convenient, accurate and quick. , To reduce the impact on building users.
In addition, buildings built with BIM technology can also be pre-installed with sensors during the project. Once a fault occurs, the device can easily detect and notify the central control center for real-time processing.
In addition, some buildings will also use sensors for pedestrian flow statistics, in conjunction with BIM 3D image space for data analysis, to calculate the amount of traffic or usage in the building's indoor space, and to prepare for expansion or addition plans.
For example, in Singapore, which has already used BIM technology, some hospitals have such devices. The relevant management personnel pointed out that this will enable them to know in advance when they need to make better planning for the expansion of the hospital.
BIM technology can also make the impossible possible.
In the past, architectural designs that were quite different from others, such as buildings with strange or irregular appearances, including the Hong Kong Polytechnic University Jockey Club Innovation Building, which is shaped like a surreal "boat", are extremely creative in appearance and are also used Three-dimensional drawing and BIM technology are used to determine complex geometric structures, so that the construction process that is more difficult to calculate accurately becomes smooth, and the irregular geometric external wall components are more accurately planned and manufactured through BIM technology.
Therefore, the application of BIM can provide powerful design and management decision support for different construction and engineering stages, avoiding the conflicts in the construction location of the construction project, and making the dream come true for the creative architectural design and efficient operation. one day.
"01 Medical Clinic" cooperates with senior engineer Yuan Bailiang, and launches a column "Yuan Tu You" every Monday to share the big and small things of engineering and medical treatment.
Yuanboliang has always been committed to promoting the professional development of the engineering industry, and has just stepped down as the president of the Institute of Engineers.
Decades of professional journey is truly worth remembering, and I am convinced that latecomers may be able to understand the key points of the engineering profession.
We have you in Yuantu, let everyone experience it together.
