1. 2 Introduction BIMarabia is the first E-magazine intended to spread awareness of BIM tools and workflows across Arabic region. BIMarabia is written and edited by users, targeted to be beneficial to practitioners and researchers in the field. For more information, please go to http://bimarabia.com/. This is the second edition from BIMarabia magazine English version, the growth in the construction industry in Arab World especially in Building Information Modeling (BIM) applications pushing us to develop this magazine to satisfy the needs of the market. When the Arabic version was published, many readers asked for translation into English or any other language, Thus, we decided to translate it into English. If anyone is interested in translating into any other language or join our team, please don’t hesitate to contact us: [email protected] Nothing is wiser than what Abdul Rahim Bin Ali said “ I’ve never seen a writer wrote a book without saying in the next day : If this was changed it’d be better, If this was increased it’d be advisable, If this was moved forward it woudl have been better and If this was let as it was it’d be better, This is the greatest lesson and an evidence of the size of shortage among humans. Finally, after modicum progress in this broad knowledge hopes to obtain admission and receive plaudits. Editor Omar Selim

3. 4 Introduction to those who did not read the first issue of BIMarabia magazine Building Information Modeling (BIM) is: A digital representation of the physical and functional characteristics of a building displayed as a 3D model, with the added capability to integrate a whole array of design and construction data related to cost, schedule, materials, assembly, maintenance, energy use, and more a digital representing of physical and functional characteristics of a building in three-dimensional form (Jackson, 2010) Or simply: making a virtual model of the building on the computer so you can find out the information you need as an engineer and as a project manager and stakeholders The BIM was found as a result (an innovative solution for problems inherent in the AEC sector) of the problems that existed in traditional ways. If there was no BIM, we would have created a system that avoids problems that occur on the site as a result of discovering conflicts and problems during work. If there was no BIM, another system would have been found in any name and may have been abbreviated BIM also or virtual building Introduction To BIM Omar Selim

4. 5 Virtual Building. One of the important issues is that, BIM is not limited to buildings only, it could be an air plane, submarine, artificial body parts, etc... BIM is the abbreviation of Building Information Building and here is the question: Is BUILDING a name, or a verb? Does it mean already existing buildings or the construction process? BIM is interested in BOTH construction process and existing buildings, we use it during construction where the big benefit appears after the construction ends through the building management, monitoring and controlling. Is it intended for architectural or structural purposes?.the answer is: all involved disciplines in construction process like: arch. , structural , electro-mechanical.... What is the benefit of BIM? My teacher engineer Maaz Al-Najjar answers in an interview. In short, the benefits of BIM for both: Architectural: −Focus on designing rather than drawing −Taking correct and direct readings from the spaces and dividing them between the model −Effective management of the project according to the fact that the architect is the author of the idea of ​​the project and he is responsible for it in front of the companies' management in a healthy work environment. Construction (Civil): −Taking the model correctly (constructional elements required only, without diving in the eternal thinking to understand the model and re-work on it to become the form they wish) −The possibility of analyzing the model within its program which he works on comfortably and then re-form it with the modifications of the basic project on the BIM Server to follow-up working on it later with an alert to changes taking place to the other engineering complementary, specialties and multiple staff. −A direct calculation of the quantity related to space and sizes (and in some scenarios, calculating lengths and diameters of reinforcing bars) and extracting quantity tables directly from the model without returning to the previous drawings like : architectural , plumbing , electrical and mechanical ones. Mechanical Electrical and Plumping (MEP): Majority of work scenarios, MEP engineers have a prior experience of building needs to diameters of wires and their access as the case of push and pull circuits volumes used in air conditioning, refrigeration and so on for piping fresh water circuit and salt water... etc. But what needed is the knowledge of extension of these circuits, cables and pipes which would interfere or clash a non-structural or structural elements, such

5. 6 as ceilings and others that will be installed in the building later MEP specialists benefit in knowing the sizes for heating and cooling −Extension to show the place of trays, which cables will be extended on. −Full representation of the central air-conditioning circuits Air Ducts with the work called Collision Detection to indicate if there is any objection with the structural elements that is currently installed −A review of the project as a whole after the installation of all systems. This allows us to inspect the integrity of the original design and its lifetime. −The possibility of transferring the model to other software which the engineering staff works on for further analysis and matching specifications The benefits of BIM for the contractor: (Contractor) −Knowing the specifications required for implementation in the field. −True and accurate knowledge of the necessary building materials and other accessories (Scaffolding and tower cranes to what else of toolkits) for the completion of the construction and overall site logistics. − An estimated initial a true report for labor fees and required staff. −True inventory of warehouses and what necessary for the construction project. −Simulation of the time schedule (4D analysis) and giving the best reports for engineers’ feedback about the proper functioning of the site. −Setting up safety and evacuation plans. The benefits of BIM for workers in real estate (Real Estate Brokers and agents): the environment , the nature of the client and the property as well in addition to the site. But most real estate workers share some specific characteristics which , BIM could contribute to such as: −BIM helps in providing a true age of the property and its specifications which positively motivate the client to buy it. −Full data on the location, size, and volumes if necessary. −The possibility of providing the ready scheme to the client who wants to know everything about the property which he wants to buy. −The possibility of expanding the data included in BIM system in order to contain the real estate date associated with the property, owners, transfer of ownership and its problems data, if existing. −- Real-time reporting of leased area data of a facility (7D Simulation) The benefits of BIM for Facility Management (FM): Usually, firms associated with facility management work with the owners according to maintenance annual contracts for everything related to this property.

6. 7 BIM system is very essential according to the nature of the facility management. Some BIM software take the full model information, then add information about workers in facility management to connect them with time. ArchiFM, for instance, is one of the most common software in Britain, which works directly with the internet. It takes the property number after obtaining its model from Archicad software, then schedules the consumed items (they are often covered by the maintenance contract) within timetables in order to allow the maintenance department to follow it directly for repairing on a regular basis. This scheduling is based according to specific work hours or recording the damage when a problem occurs in the record to see what has been altered during a period, which is currently done by the accountant! Which unfortunately does not have any engineering experience of those pieces functions. Benefits of BIM for manufacturers: BIM Object in the library has become an alternative to the image that we used to see in catalogs during the eighties and before. Within BIM software, we are working on providing ready-element by the manufacturer (furniture pieces, for example) that allows the designer to choose the right characterization of this element rather than the popular way in which the designer puts a general Block for any piece of furniture and then the problems come. When it turns out that the piece which was for beautiful decoration, on the ground, there will be other dimensions for the customer piece that will be chosen by the customer (later unfortunately)... Practically the manufacturer puts all models which are manufactured in the form of BIM Objects within its own site or it will be sent by any available way like: nowadays DropBox, Email to engineer, who will put on his turn the elements as they are (dimensions, price, manufacturer’s name, date of manufacturing, shipping cost...) and so forth of information which the engineer must know and and consequently preparing answers to the client and never leave that to the last moment.
