Introduction
Digital fabrication is coming into the construction industry to create precisely crafted and complex buildings in response to the new competitive environment and construction market demands. Thanks to advanced technology, the good revolution can be seen in most industrial activities. Almost all of the industry sectors are trying to keep themselves up to date with new related innovation to boost their sustainable growth. However, unfortunately architects and construction engineers have been more conservative despite all of the massive global investment in the construction sector. This conservative trend was started many years after great prosperity and success in the other industries. As an example, in comparison with the more developed automotive industry, the construction industry has been weighing the pros and cons of doing automation, and it is still under development. Despite some limitations and lack of information over the 80’s and even 90’s, but the current status indicates good progress. Today, most of architectural design is no longer possible without computer technologies. The models have become more complex and require advanced tools to understand design codes and implement fabrication processes. It can be said, that the advanced automated tools with a user-friendly programming system can bring incredible solutions for architects and construction engineers. Many researchers have made significant studies to consider all possibilities and limitations of digital design-construction in various types of procedures.
Advanced CNC fabrication tools and 3D printing machines have made notable improvements in the construction industry. The benefits of this new approach have been developed over many years to increase...

When trying to design for automated construction systems, all parameters of a construction process must be integrated accurately and constantly to satisfy relevant parties, and finally, the quality of construction materials and products in terms of geometry, physical and design aspects will be changed. In order to reach automated construction goals, all the following aspects have to be fulfilled:
- Freedom in esthetic and design - Determination of the production costs before the execution of work
- Determination of the production time before the execution of work
- Guaranty and transparency of the price
- Continuous production - Definition of quality
- Control and transparency of the quality (ref)
Thanks to cutting edge technology and robotic systems, all these aspects can be considered through data integration and process programing.
The manufacture industry has been developing since the industrial revolution, however with the evolution of some advanced technologies and the widespread of specialized Computed Aided Design (CAD) software, the traditional way of manufacturing products may be about to change.
The paper presents a detailed discussion on implementation of BIM in a construction project by defining a BIM team in the various phases of construction i.e. from conception to commissioning. Also, the paper presents a brief discussion on processing the information utilizing the i-rooms.
Constant progress monitoring at construction sites is crucial to reducing cost and schedule overruns and enhancing quality control, documentation, and communication [1]. Therefore, there has been extensive research on automating the monitoring processes to ensure that the project managers can make informed decisions and take preventive measures at the right time. The state-of-the-art technologies for automated progress monitoring mainly include radio frequency identification (RFID) and three-dimensional (3D) model-based approaches such as laser scanning and vision-based augmented reality methods.
These requirements might seem obvious at first, yet it is exactly the demand and supply on each one of them that causes the limitations and control of this technology. The 3D printer is no longer an equipment that can only be found in a scientific lab, but people can buy it on Amazon with the price from 600 to 2000 dollars. Moreover, there are numerous companies which are starting to invest new functions upon the 3D printer such as the three types of 3D printers that have been advertised in the “Top 3 Best 3D Printers You Must Have” video: “the Tiko, the Palette, and the Moonray”. For instance, the Tiko printer is a new type of “uni-body” 3D printer which prevents the unstable printing problem caused by the traditional “separate three-piece rail frame”. Also, its 1 kg rolls, large “internal filler” and the “close-build chamber” also promises the project to be more “reliable and accurate”.
The main goal of this paper is to convince the entire construction world to incorporate robotic systems when managing modern buildings to save manpower and improve efficiency. The objectives of this paper include:
When starting construction on a new building, there are plenty of things that can and will go wrong. You will start to lay out the plumbing and find that it clashes with a wall or beam that cannot be moved. To finish your project, you must take more time and more money to adjust to the new layout. Another scenario is the owners won’t let you start construction because they can’t see the end result or where the specific design implements that had asked for are located. For the past few decades the architecture, engineering and construction (AEC) industry has been looking for a solution to this problem. Projects would be set back due to design oversights. Without anything to predict these problems before they happen, these little setbacks were a common occurrence. Once building information modeling (BIM) was born, it was like their prayers had been answered. The future was here.
There are several advantages of this traditional route in the construction industry. First, the designs are completed before tender and tender can provide good time and cost control. Also, the tenderer can receive complete information and design and they can be bidding on the same basis, so the competitive is fair. Moreover, this is design-led and the client can change the design ability, so the level of functionality and quality will be increased in the overall design. And then, it is relatively easy of variations to arrange and manage if the design will be changed because client’s needs and technology. Also, traditional paths are a tried and tested route, so it is well established and the market is very familiar with. Furthermore, it is good price certainty at the award of the contract because of full set information.
Technology has developed to such an extent that we can now manufacture products, previously only possible with expensive machinery, practically right in our living rooms. One such approach is the ability to use a special machine called the 3D printer or the 3D printing machine to create three dimensional objects, by means of an additive process.
Computer Numerically Controlled, (CNC), Machine tools are often employed for machining raw material stocks into completed designs by undertaking a number of such instructions. CNC Lathes are most likely probably the most broadly known utilization of this engineering science. They spin a block of fabric so it may be cut, sanded, drilled or finished, using the finish result as being a completed three-dimensional item. The truth is, CNC lathes are merely just like a classic-fashioned turret lathe, but running under computer control.
Primary production of homogenous goods and several processes are undertaken for the finished product to be realized is what is called process costing. All stages of processing and costs accrued during manufacturing of a product will be added to the final batch of products. Keenness is
3D printing has allowed designers, engineers and manufacturers to print models for complex designs that was not possible with traditional methods. This technology is used to materialize complex components that are stronger and lighter than the traditional
However, prefabrication is starting to gain momentum in the New Zealand construction industry. This is explored further in the section, ‘3.0 Theoretical Review’.
The standard application for 3D printing has generally been prototyping in mechanical and automotive settings rapidly. Since getting to be in mainstream, 3D printing has entered into various markets. Around all the application areas, auto...
There are 25 major specialties in engineering that are recognized by professional societies. In any one of those 25 specialties, the goal of the engineer is the same. The goal is to be able to come up with a cost effective design that aids people in the tasks they face each day. Whether it be the coffee machine in the morning or the roads and highways we travel, or even the cars we travel in, it was all an idea that started with an engineer. Someone engineered each idea to make it the best solution to a problem. Even though engineer’s goals are similar, there are many different things that engineers do within their selected field of engineering. This paper will focus on the architectural field of engineering.
