Revit includes tools for architectural design, MEP and structural design, detailing, and engineering, and construction professionals, standardized Revit work, sharing and BIM collaboration, connecting multidisciplinary teams in the cloud for faster project delivery. The field of MEP (Mechanical, Electrical, and Plumbing) has lot of Components, Systems that will be of plug-and-play type procured from Mechanical Product companies like Pumps, HVAC Equipment, and Ductwork, etc. There is a need to place these components with the right representation to present to various stakeholders. These Revit files can be dropped into a project to show the true fit of the size and performance of the equipment/Product in relation to the rest of the application. There are many Mechanical Product companies are also not far left behind to adopt BIM to support activities related to construction and take up the challenges above.

BIM contains three-dimensional renderings of the products with all the technical metadata attached. BIM offers crucial advantages to all the parties involved in construction and operation. From consultants to architects, owners to operators to the one who maintains the facility. They all benefit from easily accessible, complete and precise building information. By digitally documenting all the details, a project can be strategically planned, checked and executed in a clear way. These guarantees result and can be made on a more reliable basis at an earlier stage.

3D Rendering – Changing the Landscape of Mechanical Product Design

As technology progresses by the day, 3D rendering has a progressively significant part in the mechanical design process, allowing illustrators and designers alike to enhance and display mechanical models before hitting the market. The 3D rendering reputation also lies in the way it helps drive modernization, also allowing OEMs to achieve better quality results and faster time-to-market.

A mechanical product typically like Valves, Pumps, HVAC Equipment’s, Lights, Fixtures, Fittings, Switches 3D rendering should preferably include –

• A description of the 3D model geometry.
• Correct Orientation to geometrical shading
• Light source conditions, with position, type, orientation, etc.
• Conditions for virtual camera locations

3D rendering of a mechanical product can not only add genuine lighting, shadows, textures, colors, etc., but also allows creative illustrators the flexibility to create an intangible mechanical render for showcasing products as relevant as possible.

Advantages of Using 3D Rendering for Mechanical Product Design

There is a reason why more than 80% Mechanical design engineers turn to for high-quality product design. A polished, high-quality render make sure all the hard work translates into functional and aesthetically pleasing product designs. Mechanical product 3D rendering can –

• Help Design Engineers and OEMs weed out and remove product deficiencies before final production, thereby saving a lot of time and money. This is especially useful when the product has a complicated design.
• Allow trial and error while designing the look and feel of the mechanical product, including textures, colors, etc., without having to develop separate rapid prototypes.
• Pre-defined HDRI scenes to ensure better lighting and motion blur effects, which can then be reused again and again.
• Design proposals which are presentable in an effective manner to stakeholders and investors, as well as create a good Marketing material.

Starting 2020, all projects that is subject to public tender in US must be planned and built according to BIM! “Starting 2016, the Public had made BIM compulsory for all public sector projects over $50M and now starting 2020 all public infrastructure projects must be planned and executed according to BIM. Many major economies today are considering a National BIM Mandate or already have one in place because they believe BIM adaptation is a necessary step towards minimizing the lifecycle Building Costs”*.

This calls for creating family of products to be there in the product library ready to be adapted and used. A system family, which can be used by system and standard family, which can be created and used by several users must be created. This helps in various AECs, OEMs to be BIM Compliant.

 Below are the few examples of BIM Revit family.

• Examples of BIM Revit Mechanical Family Creation like Pumps, Pipes, and Valves etc.
• Examples of BIM Revit HVAC Family Creation like Fan Coil Units, AHUs, Diffusers, grilles etc.
• Examples of BIM Revit Electrical Family like Switches, Sockets, Lighting Fixtures, JBs, etc.
• Examples of BIM Revit Plumbing Family Creation like Pumps, Fixtures, and Valves etc.
• Examples of BIM Revit Devices like Measuring Devices, Gauges, and Fittings etc.
• Examples of BIM Revit Firefighting Family Creation like Sprinklers, Fire Extinguishers, and Cabinets etc.

has evolved over a period of time, the complexity of analysis which used to contain numerous iterations of formulas have now been automated with tools like ETABS, STAAD. Pro, ROBOT, TEKLA and others. These tools results in advantageous outcomes including but not limited to safe, stable & durable structure along with optimization of design & cost-efficient structures.

Hospital & Educational Buildings are special structures with high importance factor ranging around 25-50% analysis score than the residential or commercial structures.

Seismic resistance of a building can be increased by adopting different types of structural systems viz., seismic isolation system, energy dissipation system and active control systems etc., which enhances the seismic behavior of a building by dissipating the lateral forces without damaging the structural elements. The development of new structural systems and devices will proliferate the non-traditional civil engineering materials and techniques. By adopting such advanced system approaches based on dynamic analysis gives better representation of the behavior when simulated for conditions.

Seismic Importance Factor

However, as we understand the process can be further improvised with the help of design tool APIs (Application programming interface) by integrating and leveraging

Following are the most important characteristics for Earthquake-resistant building designs that influence their structural integrity:

Stiffness and Strength

When designing earthquake-resistant buildings, safety professionals recommend adequate vertical and lateral stiffness and strength.

Regularity

This characteristic refers to the movement of the building when pushed in lateral directions. Safety professionals and building designers want the building to move equally so as to dissipate the energy without placing too much force on one side or another. If a building is irregular, then weaknesses will become apparent when the building sways. The weakness will compromise, and the structure will see concentrated damage – which compromises the structure as a whole.

Redundancy

Possibly one of the most important safety characteristics when designing for safety, redundancy ensures there are multiple strategies in place in case one fails. These can potentially add to the building cost, but redundancies prove their worth if/when a natural disaster such as an earthquake occurs. Safety professionals advise equally distributing mass and strength throughout the structure, so strength isn’t solely reliant on one factor.

Foundations

A stable foundation is a major characteristic of building a large structure regardless of natural disaster risks. It is critical for a building’s long-term survival, and a stronger foundation is necessary to resist an earthquake powerful force. Different areas have unique foundational characteristics that define how a structure’s base needs to be reinforced. Professionals have to closely observe how the ground reacts and moves before building. Buildings designed to withstand violent earthquakes have deep foundations and driven piles. To stabilize these drastic measures, the foundations are connected so they move as a unit.

Continuous Load Path

Tying into the stable foundation characteristic, structural and nonstructural components of a building need to be interconnected so inertial forces dissipate. Multiple points of strengths and redundancies share the force instead of the quake splitting the foundation apart. This is the continuous load path characteristic that safety professionals, architects, and engineers must remain wary of during design. If the structure is not comprehensively tied together, components will move independently, and collapse will be imminent. The continuous load path is the earthquake’s journey through the building – laterally and vertically. It is vital the path is intact or else it won’t be able to dissipate an earthquake’s powerful shudders.

Earthquakes happen less frequently than other natural disasters but building earthquake-resistant buildings protects against all-natural disasters. Safety professionals keep people’s safety a priority when researching and developing protective strategies for structural integrity. Due to the amount of synergy needed to develop earthquake-resistant building provisions, safety professionals work closely with other fields. They have to appreciate multiple factors they may not be experts in and communicate with other professionals to find the most effective solutions.

Hospital buildings and educational building being categorized as important structures, a reliable solution with safety factor and rigorous iterations done for the proper behavior of the structure is adopted. It takes into count of stiffness, torsional regularity, overturning, drifts limitations to ensure the safety of the structure.

At while we do the Design & Analysis of a structure, we consider the above characteristics as well as factors like Response modification, Importance factor, Seismic zone etc. from international design codes depending upon their types, occupancy, region etc.

1. Added Dimensions: This feature enables work to be done in three dimensions in addition to cost and time dimensions. It is possible to view cost estimations and the bills of materials as work is being done on a design. Most importantly, it allows the preparation of time schedules which can be adhered to in order to achieve efficiency.
2. Virtual Information Model: Designers can share a project’s virtual information model with principal and sub-contractors as well as the operators or owners of the facility. This feature ensures that information loss during the period of sharing between stakeholders is kept to the barest minimum. Owners of complex structures can take advantage of a more extensive information database.
3. All Encompassing System: Every single process like project management, cost management, facility operation, among others is supported by BIM. In simple terms, BIM is useful throughout a building’s life cycle.
4. BIM Management: The purpose of this feature is to manage information systems efficiently all through the life cycle of a project. It supports the tracking of an object-oriented BIM against any performance objectives which the stakeholders set.

1. Capture Reality: BIM offers more than paper does in the way it captures reality and streamline project preparations. Mapping tools combined with images of Earth makes it possible to access aerial imagery, digital elevation among other things.
2. Maintain Control: With the provision of features such as auto-save and connections, it is possible to project history which reveals how much time was spent working on a model. This eliminates the corruption of files as well as its disappearance.
3. Improve Collaboration: Sharing models is a breeze with BIM compared to drawing sets. This enhances collaboration through the use of tools designed for different disciplines. As a result, everyone has a chance of making an input towards the design of a project before it is finalized.
4. Processes: It offers an increased speed and efficiency in the way things are done. For instance, it is so much easier to create spaces automatically from Excel to BIM Revit.
5. Policies: There will be a need to protect companies as they share information. This will enhance collaboration between stakeholders. It could be through the use of an electronic release form or an application of filters to any information which is shared. The tactic will minimize risk while the workflows that BIM relies on are streamlined.
6. People: For change to be adopted, the people involved have to be on board. To make good use of the technology offered by BIM, strong in-person relationships have to be built. To avoid the risk of obsolescence, new technology needs to be embraced in addition to a willingness to learn it. BIM will encourage innovation and investment in training, education, and development.

The post 54% of the Industry believes BIM is the way forward in Building Engineering. appeared first on �ۿ۴�ý.

A workable definition of BIM is, “A model-based technology that can combine, among other things, the design, fabrication information, erection instructions, and project management logistics in one database, providing a platform for collaboration throughout the project’s design and construction phase.”

U.S. is at the forefront of BIM processes and technologies:

An industry study noted that North America is the most advanced continent in terms of adopting BIM in a big way followed by Oceania and Europe. It also noted that there is a strong correlation between the advance a country has made overall and the employment of BIM services. More significantly, the study noted that North America, Europe, Oceania, and Asia are advancing rapidly toward the mature stage of BIM.

Adopting BIM can result in the more efficient use of resources; the benefits accruing to the stakeholders in embracing BIM are several, chief among them being

• BIM provides all stakeholders involved in an AEC project not only the proficiency to visually coordinate building systems but also the skill to pinpoint conflicts among them.

• Cloud computing platform based software coupled with the ability to update data in real time allow users to derive immense benefits, the more tangible among them being the saving in time besides the saving in costs.

• Users of BIM technologies don’t waste their time in exchanging project information.

• Building elements are represented as 3D objects along with relevant and accurate information

• Consistent and faultless data is updated in real time on all views of the project if changes are made in any view

• BIM models created at the start of a project ensure deep and perfect collaboration among all those involved in the construction leading to improved communication for enhanced productivity and better quality control

• Cost estimation and quantity take-offs are prepared more easily, faster and almost error free

• BIM helps to analyze thoroughly cooling and heating requirements, day-lighting choices, climatic issues, electrical line requirements and carbon emissions to arrive at optimum solutions

Short-term and Long-term Benefits of BIM

Adopting BIM results in short-term and long-term benefits. While short term benefits can immediately be felt, long term benefits accrue after sustained adoption by all stake holders.

Some of the significant short-term benefits are:

• More reliable forecast of costs of construction

• Fewer requests for information

• High quality of project

• Deeper collaboration among team members

• Almost nil conflicts

The long-term benefits that accrue after sustained adoption are:

• New business opportunities

• Shorter project duration

• Enhanced profits

• Lesser construction costs

• Lesser litigations and claims

Tangible Benefits of BIM Adoption

One of the latest study done by a leading Data & Analytics organization, among general contractors (GCs), construction managers (CMs) and trade contractors (TCs) with $50 million or more in annual construction value besides architects, engineers and contractors confirmed the findings of earlier studies that larger companies are more inclined to adopt BIM and reap benefits than smaller companies.

The study is quite revealing as to the status of BIM in the U.S. and the highlights are as follows:

• 50% of all contractors employed BIM in about 50% of their projects

• While most GCs and CMs produce their own models TCs use models produced by others. However, when TCs develop their own models and use them they have acquired greater value from them

• Structural fabricators, HVAC contractors and mechanical contractors tend to develop their own BIM models.

• A very high percentage of GCs believe that substantial value to a project is added on account of trades using BIM models.

• 70 percent of those surveyed reported a decrease of at least 5 percent in requests for information during construction

• 50 percent of those surveyed reported at least 5 percent reduction in final construction costs, material waste and schedules

• Lesser safety incidents were reported

• BIM standards, design modeling and planning were reported as the prime drivers of BIM adoption

• Most GCs opined that internal factors and market would drive BIM. However, CMs and TCs need some pushing from clients

• Improving information flow is an important objective of adopting BIM processes and technologies. Lesser hard copies, lesser unforeseen issues and enhanced collaboration are some of the other benefits accruing due to better information flow

Issues to be tackled for the Future

Some key issues to be tackled for the future, have been revealed by leading journals and articles as:

• BIM should be introduced gradually

• In-house building modeling should be attempted first and shared within the company before collaborating with outside firms

• BIM should be looked at as a cultural change rather than a technology change

• Top-down approach would be more successful than bottom up approach

• Team work and collaboration should be the mantra

• Expectations should be grounded in reality

Finally, a major advantage of MEP is its capability to perform the task of automatically scheduling of the modelled equipment and its components or elements. However, the same instance here also remains to be another challenge towards MEP engineers because of the unavailability of global specifications for similar parameters. Meanwhile, style guide used by the Revit software gives the acknowledgment for both standards and efforts applicable in giving directions to the users when it comes to proper identification and utilization despite the lack of convention that is agreed on as at present.
