The role of BIM in prefabrication period

BIM is used to provide digital representation of the building process in 3D with the scope of a 4D (time) and 5D (cost) of data to minimize errors, enhance effectiveness and decision-making.

With improved perceptibility and clarity throughout a project to ensure that things remain on the schedule that’s been dedicated to and within the calculated budget being proposed, BIM tools provide substantial ROI for architecture, engineering and construction (AEC) professionals.

Besides, base-level geometry of a structure, BIM comprises of spatial relationships; mechanical, electric and plumbing (MEP) components and the quantities and cost estimates for the required building materials. If any modification is made, associated objects are updated along with it, all in a centralized model so that each team member of the project can get access of that model.

BIM produces a broad, digital picture of a project to facilitate the project stakeholders to have clear view concerning what resources are essential and when, as well as reduce the chances of over- or under-estimating the time and money the project will require.

The objective of prefab and modular methods is to lessen the time required to fabricate a structure on the jobsite, as well as integrate MEP components into the panel or module while fabrication is going on. BIM contains these components in the entire building model and makes trade-to-trade coordination better.

In prefab and modular construction, assembly requirements are altered since the piece, panel or module design is calibrated. As soon as the design gets ready, BIM can generate visual-based manuals, in place of written instructions so that the workers can get a clear idea of the new steps for fabrication.

Building in the virtual space is incorporating the new technologies like virtual and augmented reality.

Virtual reality can offer an immersive understanding of the BIM model and a supplementary resource for AEC professionals to examine the design options and find out design errors.

AR facilitates to layer BIM models with real objects in the jobsite as a reference point during the assembly process and avoids the construction errors.

Benefits of integrating BIM Level 2 with the project

The design is considered as the most vital phase of any project and the design should be proper prior to go ahead is the basis for smooth delivery and successful completion. Throughout initial planning phases, manufacturers and specialists can provide a wide array of benefits.

With collaboration, main contractors and architects can establish technical and estimating support as well as get benefitted from manufacturers’ consultancy and increasing knowledge of products and methods currently available that would fulfill the requirements of main contractor’s like offsite solutions or alternative materials.

Involving all related parties at design phase develops a collaborative approach from the beginning. Dealing with all the options obtainable to them, and getting manufacturers to participate in initial technical meetings, signifies the plan of the project on the whole is more up to date. Devoid of proper feedback at the conceptual and developmental design phases, the design during the project will always encounter modifications which possibly lead to both delays and extra costs.

Integrating BIM Level 2: Here, lies the importance of Building Information Modelling (BIM) Level 2 . The concept of BIM refers to the method of designing, constructing or managing a building, infrastructure or landscape asset with electronic information. Practically, it signifies that a project should be designed and constructed with data sets and images digitally, prior to visit the site. The purpose of BIM is to meet time, cost and quality needs by handling the project with a more organized and consistent method of work.

Collaborating from the starting of the project, all parties function collectively with the equivalent methods to develop a comprehensive and all-inclusive design that defines all required materials and methods employed as well as provides a final cost and timescale to hand over the project.

The successful completion of a project mainly depends on the Employer’s Information Requirements (EIR) and the BIM Execution Plan (BEP).

With the EIR settled throughout the vital design phases, it describes the project along with the implemented standards, necessary outputs, when these will be delivered and in what format, as well as any supporting documentation. All the parties associated with the project can get a clear conception of what is desired and to turn into BIM Level 2 certified, a customized BIM Implementation Plan (BIP) should be made.

Inside BIM, the BIM Execution Plan (BEP) belongs to a vital document as it sustains project integration. A written plan that gets all of the tasks and relevant information collectively as specified in the EIR, with all the stakeholders and processes taken into account.

By analyzing in the design phases, this BIM documentation is produced and can support the rest of the project during the construction phases right through to building handover.

With the implementation of BIM Level 2, allotting time in design and planning, and consulting with all related parties to receive their valuable specialist perception, the main contractor gets the ability to create an informed, fixed and detailed design to be utilized during the project as well as facilitates to guarantee timely, on-budget delivery and successful execution of the project.

How BIM was applied in £150M Royal Hospital for Sick Children and Department of Clinical Neurosciences project

The £150M Royal Hospital for Sick Children and Department of Clinical Neurosciences is considered as the single largest project that was designed by HLM Architects. To carry out this complex project, the project team had implemented UK Building Information Modelling (BIM) Level 2 from the beginning of the project.

 

The project team had embraced a “full BIM Level 2” working surroundings and gradually formed a ‘Project Information Model’ or PIM all through the design and construction phases.

 

That PIM comprises of structured graphical and non-graphical information which are preserved in a Common Data Environment (or CDE); a common online space that is available to all concerned parties.

HLM Architects substantiated their graphical information models in ARCHICAD. The information model of the project was formed recurrently over time. HLM’s Model Manager received a graphical information model files from across the design team and supply chain on a twice-a-week basis, afterward integrate or ‘organize’ them into a single model for evaluating in design co-ordination meetings.

All the project related drawings are generated in the 3D model, in ARCHICAD. The mass [of the data] is then exported as PDFs or Excel spreadsheets and uploaded to the CDE.”

 

By utilizing PDF or Microsoft Excel format, the information was made available to all sections of the supply chain.

In the project, there were advanced mechanical and electrical installations and huge amounts of equipment. Besides, a very data heavy project information model is also required for the project. To resolve this problem, the team seldom loaded-up the complete federated model rather than they divided it into controllable sections, only looking at the specific information they needed to at any one time.

 

By producing the comprehensive design in a BIM surrounding, a robust information model is formed for being analyzed on site.

Heritage BIM Is Ideal For Documentation And Development Of Historical Structures

The application of Building information modeling (BIM) becomes more versatile when it offers huge benefits in the documentation and development of historical structures in a system known as historical BIM (HBIM). The process is complicated for transforming point clouds into a 3D model as there are lots of asymmetrical geometries in the concerned buildings. So, various semi-automatic parameterization tools are required.

Historical building information modeling (HBIM) stands for a semantic-aware database of historical buildings, through which the geometric model is associated with explanatory multi-source information. Historical buildings generally comprise of stratified artifacts along with non-regular and complicated geometry, contrasting to present constructions which normally contain regular geometry. Reality-based spatial data that is generated from cutting-edge geomatics 3D modelling methods can deliver a perfect replica of those buildings, containing all the related information, even though the diversified characterizing shapes are a big challenge at the time of modeling the geometry. Often these shapes are remodeled by hand, as there are limitations for impressive automatic recognition. The aims, structure and scale – and consequently the projected level of detail of the model – significantly impact the system to data acquisition (sensors, accuracy) and data processing.

The workflow for HBIM projects commence from data procurement from different sensors in relation to the necessity of context and the projected outputs. Then, the surveyed point clouds should have been pre-processed and curtailed with different systems and standalone software, and possibly modified for segmentation by means of automatic or semi-automatic object recognition into a BIM platform. Besides, elements are modeled and transformed into an approximation of reality in line with parametric rules, so it is likely to adjust each illustration of the model. As a final point, the shapes and the identities of objects should be associated with proper and sound relationships in accordance with the semantic definition of entities. After this, the model is ready to be explored with other information for analysis and monitoring over time. On the other hand, the manual creation of 3D models linked to as-built BIM is complicated and laborious. As the costs and skills necessary for manipulating the data signify that this approach is not justifiable and more automatic or semi-automatic tools for parameterization of metric and non-metric information are essential.

BIM platforms come up with some standalone embedded tools or plug-ins toward 3D modellers, viewers, analysers. They facilitate the best use of point cloud and processing with the intension of generating geometric modelling, feature extraction and parameterization in heritage buildings. Some commercial ones comprise of ArchiCad BIMx by Graphisoft, Scan-to-BIM by IMAGINiT, Revit by Autodesk, BIM360 by Autodesk, Recap by Autodesk, PonitSense by FARO, Leica CloudWorx, Green Spider, Bentley MicroStation V8i and Tekla Structures. Some open-source alternatives are Edificius, Tekla BIMsight and Autodesk Navisworks Freedom by IMAGINiT.

How Turner Construction applied BIM and Lean construction method to successfully completed the Sibley Memorial Hospital project in Washington

Senior leaders of Turner Construction, an international construction services company from North America, had successfully implemented BIM and lean construction systems in Sibley Memorial Hospital project in Washington, DC that saved huge & significant times in construction scheduling.

The team of Turner Construction who worked in Sibley Memorial Hospital project Sibley, applied BIM to design and pre-fabricate modular corridor rack systems to assembly the mechanical, electrical and plumbing elements for individual floor of the hospital.

The project team members modeled 157, 20-foot racks through BIM as well as constructed and accumulated off-site and supplied for placement.

By incorporating lean practices with the modeling software, the project team members were able to perfectly execute works like assembling ductwork, cabling and piping early on, at just about the same time when construction excavation commenced.

For setting up the rack systems, the original schedule extended four to five weeks for each floor. But here, the project team members got benefitted with the modularized racks, to finish each floor in four to five days.

The complete workflow was greatly improved with the superior communication and collaboration process. Building Information Modeling together with Lean practices had facilitated to make the individual building progression superior which brought complete efficiency and the schedule was boosted up by two months.

It has also delivered enhancements in authentic commitments from subcontractors facilitating more organized planning for the project. The prefabrication of corridor racks and patient room headwall units quickened the interior fit out work immediately the concrete re-shores were eliminated.
