Building Information Modeling enables error free plus speedy construction

Error free construction had always been the most desirable thing for architects and engineers prior to the advent of Building Information Modeling (Virtual Design and Construction). But it (flawless construction) remained an impossible activity for design and construction professionals for centuries until and unless they began using digital design for the execution of construction projects.

The parametric model-based digital design which is brought into picture by Building Information Modeling, helped a great deal towards error free construction or seamless construction. BIM technology is used by design and construction professionals for developing parametric models for architecture, structure and MEP BIM Services before carrying out any kinds of field activities associated to real time construction.

Parametric modeling allowed architects and engineers to easily improve building design whenever required during pre-construction. Whereas it was very difficult for them to improve architectural, structural and MEP design generated through CAD software, because the parametric modeling element remains missing in them. The most indispensable or significant thing about 3D parametric models is that they are swiftly altered by design and construction professionals as per project requirement.

That means if in case errors are found in the design which is developed through CAD packages, their rectification becomes highly difficult for architects and engineers. Whereas if same kind of problem is confronted by design and construction professionals with the design developed through BIM application Revit, it can be easily dealt by them in very short time.

The reason is that it is very convenient to modify parametric models. This ultimately indicates that it becomes easy for design and construction professionals to rectify element collisions through parametric models which are developed for different building trades.

So, when design and construction professionals identify BIM Clash Detection Services between elements during clash detection and coordination services, they can easily resolve them.

Use BIM for speculating project outcomes and for controlling them

When it comes to speculating project outcomes and altering them for better results AEC professionals can make use of make use of the information that is contained in 3D, 4D, 5D and 6D models. They can carry out constructability review and identify the problems from the entire construction process. If effective constructability review is performed by design and construction professionals during early design phase then they can manage to understand complex building problems can take precautions for the reduction of wastage, design errors and project cost.

When BIM Modeling Services are reviewed during preconstruction all the building stakeholders discuss about project outcomes. They speculate the impact of design intent on project’s productivity and if they come across that building design is not that effective they make strong and effective decisions on its alteration.

When building disciplines are designed independently collisions between their elements become kind of obvious. So, for controlling the collision of architectural, structural and MEP elements during actual construction design and construction professionals have to execute clash detection and coordination services. For performing clash detection, project review software Navisworks Manage is optimized by AEC professionals.

Revit models are imported in it and collisions between their elements are identified by executing clash tests. Clash detective which is a highly valuable tool within Navisworks Manage is used for carrying out collision detection between elements of multidiscipline models. Hundreds of hard and soft clashes are pointed out by AEC professionals when they compare model elements for interferences.

CAD Drafting Services and construction professionals come across with numerous scenarios wherein they find elements overlapping each other; such collisions are called hard clashes. This happens due to the fact that design teams belonging to different disciplines by mistake allot same spaces for their elements, so when they are coordinated together elements struggle for same space.

But such situations are sorted out quickly after clash detection when design and construction professionals become clear about the collisions. They go ahead and make important alterations in the space allotted to elements. Now, space is allotted in such a way that elements of different disciplines can effectively coexist with one another. In this way rework which can otherwise lead to budget overruns can be successfully controlled by AEC professionals.

Reviewing warnings displayed for monitored elements is integral part of coordination review

Before going ahead with the description and explanation of coordination monitor warnings, I would like to through some light on coordination review. What is coordination review and why is it performed by Revit users? Well, coordination review is a quintessential step in multidisciplinary design coordination, wherein in BIM modelers link each other’s Revit models for communicating design information.

When interdisciplinary Revit BIM Services models are linked by modelers they establish a monitoring relationship between elements of linked and host model with the assistance of Coordination Review tools such as Copy/Monitor.

With the support of Coordination Review tools, warnings can be reviewed by Revit users between elements belonging to host model or else warnings can also be reviewed between the elements of both linked and host project.

A coordination monitor warning is only displayed by the software if modifications are made to the monitored elements. If in case a monitored element is either deleted or changed Revit immediately displays warning for informing users about the change.

On what situations warnings are displayed by Revit

• If in case an original monitored element which is a part of linked model is changed then Revit displays warnings about it.

• Revit also displays warnings if changes are made to copied elements in the host project.

• Another situation for which warnings can be displayed includes the scenario when changes are made to both original monitored elements and elements which are copied in the host project.

• Apart from this warnings can be displayed if an original element belonging to linked project or host project is deleted.

For successfully addressing these warnings Revit users have to take necessary actions within Action column of Coordination review Dialog box. Actions such as Accept the difference, Reject, Postpone and Modify/Rename/Move etc can be taken by users for addressing warnings.

For example if Revit users want to welcome a change in the design that is made by them during BIM Coordination Services they can go ahead with ‘Accept the difference’ action under Action column within Coordination Review Dialog Box. In this way depending upon the requirement of the change in the design they should take appropriate actions.

BIM modeling services: Get high end multidiscipline 3D models by hiring them

Today architects and engineers completely rely on multidiscipline 3D models for going ahead with the construction of a building. In other words design and construction professionals cannot even think of proceeding with construction work until and unless they have the accessibility of 3D models that are developed for different building disciplines.

Today all kinds of construction related problems are sorted out by architects and engineers with the assistance of virtual models in the preconstruction stage itself. For safe and seamless construction it is believed now that a building must be constructed in a virtual world first. And this is done by developing multidiscipline 3D models in Autodesk application Revit. That means architectural, structural and MEP design is first represented by AEC professionals in 3D which helps them in analyzing the design for its validity or effectiveness.

That means a better perspective is gained by AEC professionals about the building design when it is generated in the form of 3D models. So the most important job of building contractors is that they need to find a reliable service providing partner from which they can hire BIM modeling services in the preconstruction stage. It is important for contractors to investigate about the performance of the service providing company before they jump into hiring its BIM modeling services. Intelligent clients would always research over the internet for figuring out the authenticity of the company in question. It is suggested to go through the reviews of the company over internet for knowing about its reliability.

After successful investigation clients can approach the company for hiring BIM modeling services. The next step in hiring BIM Services from a service providing company is to give them a detailed description of how they want the models to be created in terms of level of details. So clear plus concise specifications must be sent by clients for the reference of BIM modelers. And based on the specifications BIM modelers develop stunning 3D models in Revit which incorporate highly critical information in them.

Specific Revit disciplines are available to AEC professionals for the development of multidiscipline models such as Revit Architecture, Revit Structure and Revit MEP Services. All these different Revit disciplines ultimately help in generating precise building design. One of the basic requirements for developing accurate models is to have close cooperation between team members of design development team which is successfully taken care in Revit. Hence Revit helps design development team members in creating high end 3D models.

Clash detection: A process that removes design discrepancies!

Over the past twenty to thirty years BIM Services has emerged as one of the most significant tool for architects and engineers in relation to building construction. Its potential is much beyond the general assumptions of design and construction professionals when it comes to tackling the complexities of a building process.

Simplification of one of the most daunting task that is ‘construction’ would not have been possible without the application of Building Information Modeling technology. Revit Clash Detection Services which an integral part of BIM is highly valuable for design and construction professionals as it helps them in identifying design conflicts between architecture, structure and MEP elements and then allows them to resolve them.

BIM software used in clash detection has the ability to detect every minor conflict between model elements which can cause design changes during actual construction if not detected during preconstruction.

Navisworks visualizes every design error and allow design and construction professionals to predict its consequences if not resolved in advanced.  Architects, engineers, design consultants and modelers review the models and predict project outcomes with the assistance of Navisworks. When project outcome is predicted well advanced in time it can also be controlled by taking necessary measures, for example if clashes are detected their consequences can also be predicted in terms of their potential to affect project productivity.

And hence solutions are provided for the conflicts accordingly by design and construction professionals. All the conflicts identified by the team executing clash detection are listed in a table within Results column and they are also grouped automatically by the software according to their potential to affect the project that means depending upon their seriousness they are divided into the groups.

When it comes to providing accurate solutions to these conflicts design and construction professionals handle them according to their impact that means clashes which can have severe impacts on the project are sorted out first. In this way different group of clashes are provided with effective solutions which can help in averting rework in future.

In this way clash detection helps in improving the design by identifying and solving all the design discrepancies much before they become accountable for rework.

BIM coordination checks the coexistence of elements belonging to different trades

BIM coordination an important aspect of Building Information Modeling has tremendous benefits for all the building stakeholders, who put substantial amount of efforts in project completion. Even the best and highly skilled modelers cannot stop the occurrence of design discrepancies in multidiscipline models.

Even after the application of most effective modeling software in the development of 3D models, design and construction professionals cannot claim that the models developed by them are completely error-free in terms of collision of interdisciplinary design elements.

Hence BIM Coordination Services is executed by AEC professionals so that co-existence of different elements can be measured in digital environment and design discrepancies can be identified or visualized before they actually affect construction. There could be endless reasons for the occurrence of clashes between model elements such as improper communication of design data among design development teams during design development process.

For example elements may conflict with each other due to inaccurate dimensions of a certain element or due to mistakes in the sizes of elements such as columns and beams etc. If the size of a column is larger than expected (that means mistake has been made by someone in its size) then there are chances of it colliding with some other building elements which are though kept on their right places. In other words if there are size variations in the elements than their actual size clashes are bound to occur in terms of space allotted to them. That means fight between the elements for the same space is obvious.

That is why complete clashers are detected by design and construction professionals before models developed for representing architectural, structural and MEP design are coordinated in a virtual environment. Successful resolution of identified clashes can be followed by coordination of 3D models in Revit MEP Services. As all types of design discrepancies are dealt with effective solutions there comes no obstacle in model coordination or in the coexistence of model elements. In short after clash detection process, model elements can conveniently coexist or can exist in their own places without fighting for the space.

The coordinated model generated at the end leads to seamless construction due to its error free characteristic.

Scan to BIM: In what way laser scanned data is used in a Revit project?

Emergence of Scan to BIM technology has been a great treat or feast for design and construction professionals as it has the potential to solve their complications in terms simplifying renovation work.

This technology has been around for quite some time now and AEC professionals around the world are making the best use of it for saving their valuable time and efforts which they used to apply on renovation projects when scan to BIM was far from their approach. Scan to BIM has the potential to sort out too many issues such as it works as a helping hand when it comes to scanning the structure for obtaining information from the existing structure.

Scan to BIM Services process makes use of laser scanning technology in the first place for extracting the data from an as built structure wherein the information is retrieved with the assistance of laser beams that are pointed towards the building from high quality laser scanners.

Scanning process is too important for AEC professionals as it saves their precious time when compared to manual surveying wherein it used to consume days and weeks simply for measuring the building and creating technical drawings based on the measurements. One the other hand scanning process completes the entire scanning of the structure in comparatively very less time and on top of that brings accurate data of the existing structure.

Getting accurate data for the structure in question is the most important advantage of implementing laser scanning technology on renovation, refurbishment and retrofit projects which was not that possible in manual surveying.

The laser scanned data that is obtained through scanning process by AEC professionals is recovered in raw format. This scanned data which is widely known as point cloud data is changed from raw format to meaningful file formats before it is used in Revit. The process of changing raw data into .rcp and .rcs files is known as indexing. In an .rcp file countless .rcs files are grouped together. In short .rcp file is a collection of innumerable .rcs files and both .rcp and .rcs files can be optimized easily by design and construction professionals in their Revit projects.

Point cloud data is highly constructive and instrumental in providing the precise geometrical composition of the existing structure and helps in developing accurate 3D models which contain the actual existing conditions of the building. BIM models developed with the assistance of laser scanned data are truly helpful in renovation and make the entire process too smooth and convenient for AEC professionals.

Building information modeling a new concept in the construction industry

It is no hidden truth that building information modeling is a very new concept in the architecture, engineering and construction industry. It is responsible for helping the architects, engineers, contractors and the house owners.

The ideas of BIM were first heard in the 1970s, but it was truly applied in the industry after the 90s. Since then it has been applied to all kinds of construction projects. It helps in the decision making as well as enhancing the planning regarding the building process.

Building information modeling is implemented in the architectural, structural and the MEP projects.

 3D Building information models are the prime source of the information related to the construction process. The basic BIM models are developed with the assistance of three dimensions that are length, breadth and height. These models are full of information and they assist in the further development of the building process.

Be it the architectural, structural and the MEP  BIM models they all have the sufficient information regarding their respective designs. Another important thing is that they help in the extraction of the Construction Documentation. Drawings for MEP systems, structural drawings and architectural drawings all of these can be extracted from their respective models. Construction drawings are very crucial and are referred by the architects, engineers and the contractors for various reasons throughout the process.

It’s even better if the drawings are extracted from the BIM Coordination Services Model. A coordinated model is the one which is already checked for the clashes and faults. So in other words a coordinated model is free from all kinds of errors. This clearly states that the construction drawings extracted from this model will always be faultless. Due to theses drawings which are completely error free, the actual construction process also becomes smooth.

Another thing which has now become possible due to the advancement of BIM is that time taken to complete the process and the money required in the activities can be calculated much earlier.

This has helped the contractors and the owners to manage their finances and along with managing the entire process.

Value Engineering Services assist you in adding value to your Building Projects

An organization’s success depends on how efficiently it can produce good quality deliverable by spending less amount of money. Value Engineering or VE has brought this facility to produce good quality products optimally. It is a useful approach to improve the quality of any product, good and service by implementing needful functions in a project.

In construction services, especially in BIM Services, Construction drawing services, Mechanical services, MEP services, product design services, Shop drawing services, etc. value engineering has a large scale practice in making sustainable building design, building information modeling 5D and 6D analysis, etc.

Value is the result of the ratio of function to costs.  Hence, the values of a project can be improved by improving the applied functions in a project and by reducing the project costs.

                                                   Value=function/cost

In Construction industry, value engineering process is appreciably utilized in developing good quality buildings in minimal costs. Therefore, the prime objective of VE in this industry is to construct best quality buildings and reduces overall project costs as less as possible.

Importance of Construction Drawings in Construction Engineering Industry

Architectural Construction Documents is fundamentally the pictorial and written form of representation of any construction, including every bit of detail such as wall color, furniture, floor space, material details, outlets, lighting, equipment etc. It is used as a final drawing on basis of which engineers proceed to further development.

This drawing is used as a document which specifies all necessary information and requirements such as:

• Full view of a construction including all dimensions
• Elevation view and sectional view from all sides
• Sectional view of each wall
• Manufacturer details (name, phone number etc.) of the paint colors which are used for wall painting, furniture painting etc.
• Material details of each part, e.g.  materials of window and door can be of steel, plastic, wood, iron etc., roof can be of asbestos, wood, concrete materials (cement) etc.
• Furniture dimension, materials, space occupancy, finishing (I.e. polishing type) etc.

Dimensions within a Construction drawing basically represent the position of its associated components. The written text is used for pointing those particular components for giving further description. Legends are used to give specification of corresponding components like material, color etc. of walls, doors, stairs, windows etc.

Construction drawings are fundamentally created for newly constructed buildings or for renovation of existing buildings. It can vary from anywhere between 10 pages to 100 pages depending on the type of project.

Construction drawing can be made in separate parts, like – Architectural, Structural BIM Services, Mechanical part or assembly drawing, MEP system drawing etc.

Architectural drawing plays a key role in the field of Construction engineering. It consists of:

• Exterior Elevation of a building from all directions
• Interior and Exterior Floor plan drawings
• Roof plan and truss detail drawings
• Foundation wall drawings
• Cross-section drawings of a building from various angles
• Space plan drawing

Structural drawing, which also plays a very important role, consists of the below components:

• Steel building drawing
• Joist connection drawings
• Rebar shop drawings
• Anchor-Bolt Drawings
• Structural Analysis

MEP drawing consists of:

• HVAC system drawings
• Piping system drawings
• Electrical system drawing

Mechanical drawing includes:

• Mechanical product drawings
• Equipment parts and assembly drawing

Construction drawings are created on the basis of local standard code for a building. Before proceeding to the next step, these drawings require necessary approval from the concerned authorities.

Earlier, Construction drawings were created manually using paper which was very strenuous and time consuming. Nowadays, it is made on computer using CAD tools. AutoCAD is the most commonly used CAD tool utilized for this kind of drawing. Off late, many new software versions (i.e. Revit 2014, AutoCAD 2014, ArchiCAD 15 etc.) are also being launched in the market to simplify the process of Construction Drawing.
