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. BIM contains precise geometry and relevant data needed to support the design, procurement, fabrication, and construction required to recognize the building (Eastman et al. 2008). Basically, the purpose of BIM is to simulate the construction environment in a virtual database that can be used during the physical construction as well as a virtual model for operations and maintenance after construction is finished. In the beginning, you have access all areas of the project and can determine whether certain areas will need more time in design, where various clashes may happen, or what could be changed for a lower cost. or to speed up the building phase. In his article, Salaman Azhar said, “It is important to note that BIM is not just software, it is a process and software.

Firstly, material takeoffs in BIM require the use of different methods. For example, during manual calculation of the one-brick wall superstructure, the value of 84.86 can only be gotten after subtraction from 95.91 (the external wall for the gable ends). This kind of deduction will not be possible on the software itself and that is not how the software is designed to work as well. A different manipulation would have to be done in order to get the value of 84.86. Therefore, estimators must adapt their takeoff techniques in order to extract accurate data from the model.
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.
...l estate industry. From the decision to lend money for the construction of a new skyscraper in Chicago, to the choice between the corners of a highway intersection for a new gas station, GIS plays a crucial role in allowing the key participants to make more informed decisions. Judging from the incorporation of GIS applications by today’s real estate companies, the importance of this tool will only continue to expand.
Building Construction procedures involve the erection of various types of structures. The major trend in present-day construction continues away from handcrafting at the building site and toward on-site assembly of even larger, more integrated subassemblies manufactured away from the site. Construction in the United States is the product of a diverse group of subindistries, with many individuals and organizations involved in the construction of a single structure, from the manufacture of necessary components to final assembly. The major elements of a building are as follows: (1) the foundation, which supports the building and provides stability; (2) the structure, which supports all the imposed loads and transmits them to the foundation; (3) the exterior walls, which may or may not be part of the primary supporting structure; (4) the interior partitions, which also may or may not be part of the primary structure; (5) the environmental- control systems, including the heating, ventilating, air-conditioning, lighting, and acoustical systems; (6) the vertical transportation systems, including elevators, escalators, and stairways; (7) communications, which may include such subsystems as intercommunications, public address , and closed-circuit television, as well as the more usual telephone wiring systems; and (8) the power, water supply, and waste disposal systems.
The Construction industry in the US has faced some interesting changes throughout its progression. From economic instability during the housing market crash to amazing technological advances to reduce the need for construction workers and therefore the cost associated with newly built properties in the real estate market. Beginning with the first tools ancient man used to carve their niche in the soon to be global expansion of arguably one of the oldest trades in history, construction has a rich history of trial and error, analysis and engineering that covers a very necessary skill that directly affects everyone who seeks and finds shelter, a place to work or any aspect of public works and many
Published in 2008, the Building Information Modeling Protocol Exhibit by the American Institute of Architects was developed in order to establish guidelines on the use of BIM throughout a project. This is important in that it has addressed several outstanding questions such as, the responsibilities for each element of the model, the authorized uses for the model, the extent to which users can rely on the model, the management of the model, and who takes ownership of the model. After developing a model for a dormitory building that belongs to the Polytechnic Institute of New York University, several examples can be shown that help support the compliance of the Building Information Protocol Exhibit.
From this report, it is clear that a series of steps have to be taken in order to construct or renovate a building. Firstly, a problem is defined and in order to understand this information is gathered through a survey. Once the survey is drawn up, structures are determined. After calculating loads, sizes of structural members are figured. Materials are tested before using them in real life structures, hence creating a safer structure. When everything is on the point, the structure is constructed. In conclusion, this report shows that various factors contribute to the context of a design brief.
Checktec has one common goal of bringing a new software product to the architecture market that will change the process of designing buildings. A current problem that architects and other building designers have is ensuring that all of their designs are up to code. The code that is used for all buildings is the International Building Code (IBC). Currently all designs have to be checked by hand and by multiple workers to ensure that the codes meet the IBC standards. With our new code checking technology this process will be forever improved. Our software allows for a designer to ensure that he is building up to code before he ever breaks ground on the actual site. This cutting edge software will allow architects the peace of mind in knowing that they meet code specifications, without having to spend countless hours doing so by hand, which is inefficient and costly.
Brooke (1997), explains Estimation as the technical procedure of anticipating the value of the project. Building construction estimation is the process of acquiring the construction value for the whole project before the project starts. Thus, construction attaining process depends hugely on financial management to sustain workability and smooth operations. The delay in construction is a global issue which is due to improper preparation of estimates and lack of drawings (Ajanlekoko, 1987). In accordance to Gkritza (2008), the source of delay in a project are identified to be in the initial stages, like bad quantification, errors in design and ground conditions. Thus, the purpose of a proper estimate is to foretell the cost needed to finish the

Times have changed since days of Vitruvius, the inevitable advancement in technology, rapid global population increase and an ever developing awareness of the sustainability of our environment have forced the architect into different positions in the project team Thus it can be said that the external forces that shape the environment that an architect works in does so by manipulating the relationship between the skills required to practice; the scope of expertise and the depth of knowledge. Fig. 3 indicates a diagrammatic timeline representing the changing roles of the architect over the various time periods with respect to the scope and depth of
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.
