How 4D Modeling reinforces Multi-Storey Building Construction

Multi-storey construction is a complex design and construction process. It requires the use of sophisticated design, planning, and construction tools and processes like BIM to achieve mandatory outcomes. The adoption of BIM technologies minimizes the risks associated with design and construction errors.

Adopting 4D BIM allows project teams to create an accurate and comprehensive construction based on visual planning. The use of a 4D model in the construction of a multi-storey building helps detect spatial and temporal errors before the actual on-site construction begins.

To be effective and competitive in the design and construction sector, AEC firms need to adopt progressive methods to achieve positive construction outcomes. Over funding or under funding are risks that need to be taken into account based on project timelines, and there is a need to work more efficiently. It is also important to save time and money, demand fewer resources, and not compromise on quality are specific areas that need to be addressed.

How does 4D BIM save time and money during construction of multi-storey buildings?

The addition of the “time” attribute to a 3D model results in a broadly defined 4D environment. This extra feature provides the model with greater dynamism of representing the behavior of multi-storey building elements along time. The adoption of 4D BIM augments construction and helps architects, contractors, and builders calculate accurate project timelines. It also enables a deeper understanding of large-scale projects preferably, multi-storey structures that show high-complexity at every stage.

4D BIM for multi-storey buildings ensures enhanced team coordination and communication between architects, contractors, builders, and other stakeholders. This enables improved project delivery time, streamlined project planning and time, and significant cost savings.

Benefits of 4D BIM Scheduling 

  • • Identify design errors
    • Optimize the placement of materials and structures at various construction stages
    • Improve the operation of cranes on-site
    • Enhance the organizational work performance
    • Monitor activities related to on-site preparation for labor protection and compliance
    • Safety requirements for on-site personnel
    • Make the project more constructible and productive by reducing onsite waste and rework

An architectural firm from Manchester, UK required a coordinated 4D BIM model with construction sequencing and a project intro video. 2D drawings were provided as input. The business needs were - clear design intent, save cost on design rework, devise a systematic design flow, etc.   

The challenges for the team included - technical drawings in a foreign language, five different inter-woven levels, and missing MEP dimensions of pipes and systems. 

The team at Hitech CADD Services built a fully coordinated 4D BIM model by detecting and eliminating clashes and created a time liner video for hassle-free construction. The entire project of creating a 4D BIM simulation was achieved in 2 months and delivered to the client.   

The 4D BIM model helped the client develop a clear design intent, save costs, and reduce project rework based on a sequential video. Read Case Study.

The key purpose of 4D BIM is project scheduling, but it revolves around various aspects for architects and contractors. The roles of an architect include building design, team management, prepare construction documents for structure and material, work with contractors, etc. On the other hand, contractors need to direct and oversee construction, interact with clients, check constructability, coordinate with various stakeholders, etc.

To achieve successful deliverables out of every role mentioned for architects and contractors, there is a single factor that connects all - Time. Knowledge of a contractor is key when building a 4D model for the planning process. A contractor can provide valuable feedback to build a 4D model for constructiveness, approximate construction cost, and consistency.

With a host of benefits, 4D serves as a tool to identify bottlenecks and improve coordination between various project teams.

    In what ways BIM can be used on Construction Sites?

    BIM can be used in numerous ways for construction sites. From better planning of resources and materials to improving collaboration between various disciplines, BIM is used widely to help keep the project within the scheduled time and budget.

    BIM helps construction companies gain financial benefits, increase project efficiency, prevent on-site incidents, and increase safety. BIM provides better insight for construction managers and all other stakeholders who are involved in the project.

    Ways in which BIM can be used on construction sites:

    - Get deeper insights into various aspects of building design & construction during the pre-construction stage.

    - Remove bottlenecks through enhanced communication & collaboration between various disciplines such as Architecture, Structure, MEP, and FP.
    - Accurate clash detection reduces rework.
    - Easy to understand potential hazards whilst simulating various scenarios and strategies possible.
    - For existing & as-built models, construction managers can leverage digital surveying through Reality Capture using 3D laser scanners, drones, etc.

    For one of the leading architectural firms in India, Hitech developed a clash-free 3D model for a data center building. Using Revit and Navisworks, the team of BIM experts at Hitech resolved the inter-disciplinary clashes and provided a coordinated 3D model, sheet setup, schedule, and joint details to the client. This helped the client to implement smooth and hustle-free documentation while saving on cost and time due to reduced reworks while ensuring safety on the worksite due to the use of BIM.

    BIM can empower construction projects through collaboration, onsite safety, and information management. It has the ability to predict and prevent construction challenges beginning from the design phase itself, which is why construction companies are increasingly adopting BIM for construction projects.

  • Importance of BIM for Traffic Engineering - bim

    Importance of BIM for Traffic Engineering

    In a world of construction and traffic engineering industries, BIM replaced CAD technologies and changed a lot in the industry business processes. The 3D software became indispensable and essential for the traffic engineering industry, and here are the reasons why. Firstly, we’re going to explain BIM to those who haven’t discovered it yet.

    What is BIM?

    Building Information Modeling (BIM) is a process consisted of many technologies and tools for management of digital portrayal of functional and physical characteristics of locations, places, areas, etc.

    BIM is suitable for development in numerous levels of detail. It has the possibility of varying modeling efforts for the generation of building information models.

    BIM in Traffic Engineering

    Although BIM was primarily intended for architectural purposes, it has soon developed into much more. Nowadays, BIM is an infallible part of traffic engineering. It has the ability to provide different project outcomes and designs.

    BIM provides assurance that is data-driven and ensures that projects are scheduled and delivered on time and within the budget. The information distribution is present and shared from the beginning of the project and is a crucial part of a project life cycle.

    BIM solutions are designed to improve all disciplines included in traffic engineering such as utilities, drainage, road, rail, etc.

    Such models make traffic projects easier to understand and minimize the risk and costs of traffic engineering.

    Traffic Planning With BIM

    Traffic planning requires a lot of decisions in the process. Production of solutions like entrances, exits, barriers, etc., takes numerous factors into account. In such cases, BIM uses an integrative approach for effective planning and evaluation.

    BIM models are highly detailed and enable traffic projects to be enriched with high-quality models. Designers worldwide create detailed 3D models that are an important part of projects. Detailed models provide the opportunity for quality projects and greater awareness.

    A picture is worth a thousand words, so we’ve put some examples for you to see how those models look once they’re finished are ready to be implemented in BIM designs. You can easily save your time by downloading these and integrating them into your projects.

  • Manufacturer WILO manages the data of its BIM objects on the fly from its PIM product catalogue, using the PIM2PIM technology by BIM&CO - bim

    Manufacturer WILO manages the data of its BIM objects on the fly from its PIM product catalogue, using the PIM2PIM technology by BIM&CO

    A pioneer in the use of PIM (Product Information Management) for the dissemination of its data to its BIM catalogue, WILO has remained true to its motto: Pioneering for you.

    For the manufacturer, the use of PIM is a non-negotiable: a reliable and unique source for all of the technical data relating to its products. Disseminating this data to digital twins of its products, BIM objects, was thus essential in order to guarantee its sustainability. Ralph Huysers, International Business Developer at WILO, explains: "At WILO we also have a PIM stored via an external partner with dynamic data. If we had published our BIM objects on  in the classic manner, we would have published data that would have then required an online modification on the platform, which, although the functionality is unique and stands apart from competing solutions, is not sufficient for us. PIM is the basis for our product data, and is therefore our source of information.It was essential that any data modification could be applied to the objects in real time."

    The WILO teams were thus attracted by the PIM2BIM technology by BIM&CO, which enables the connection of any PIM to In order to apply this process to WILO products, BIM&CO  began by creating generic BIM objects based on ETIM MC models. ETIM MC is an open international standard that allows you to standardise the classification of electrical or climate engineering products and that indicates, for each product, all of the characteristics to be respected and linked to a 2D plan. These objects were then enriched: the BIM&CO APIs communicated with the WILO PIM to retrieve data, and these were then translated to the BIM&CO standard using a mapping technology.

    "Thanks to our technology and generic ETIM MC models, the WILO BIM objects stored on our platform are directly enriched via the WILO PIM, which enables the automatic generation of a complete and reliable manufacturer object, without any human intervention whatsoever. The manufacturer can modify his database at any time: the information will be automatically updated in the objects on our platform and in our customers' Onfly spaces," outlines Bertrand Beudot, Project Manager at BIM&CO. A remarkable step forward in the world of BIM data management: in addition to the fact that the manufacturer has the guarantee that he can continuously offer up-to-date products to his users, this method is proving to be a real time-saver when generating the company's BIM objects.

    "Approaching geometry separately from data enables the advanced management of the data. Using our OPMS (Open Properties Management System), the technical information relating to the equipment meets all of the requirements of each phase of the life cycle of the building. The manufacturer thus ensures that he can offer products that are adapted to each business need," concludes Muriel Bourgeay, CEO for Spain, responsible for the project.
