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.

What Is 5D BIM And Its Benefits

5D BIM demonstrates completely valued parametric building components inside a virtual model in real time. With 5D BIM, it is possible to generate models which show how modifications with materials, layouts, square footage and other design elements influence the display of a facility as well as the cost and schedule of construction (dimensions four and five). It’s similar type of Macro BIM, a technology that is used by estimators to model facilities at the initial phase of design.

5D Macro BIM connects the creative form of design with the strategic function of a building’s architecture, and makes the process more apparent. 5D Macro BIM allows you to model and evaluate all the imaginative things like inventive design concepts, concise exterior finishes, unprecedented layouts, distinctively shaped and aligned departments and floors in different sizes. The costs are evidently apprehended to materials, labor or soft costs.

Benefits of 5D BIM :-

• Understand the scope of the projects in a superior manner with visual and data modeling capabilities. The costs are driven by formulas on every building system on the basis of the certain design, materials, site conditions, phasing and other parameters with reference to the owner’s timeline.

• The project team members will be able to easily understand the projected design, assumptions and cost drivers. They can obtain a transparent and perfect description of scope, cost and schedule upon which funding decisions are taken.

• Data is achieved in real time once the model is developed or modified. Substitute perceptions can also be easily searched, when owner and project team can get the cost and other data disclosed instantly. It radically reduces design and estimation cycle time. With authentic, perfect updates in real time, the efficiency is enhanced.

• Databases allow leveraging historical data as well as industry experience. Data can be utilized from particular sectors like healthcare or distribution center construction.

• All the interested parties associated with the project can visualize the end product and properly understand what’s comprised in the budget.

• The construction costs are modified automatically in real-time with the alteration in the model. “What-if’s” turns to be productive and captivating solution missions for the project team members, specifically the owner.

How BIM is considered as useful collaboration tool for real estate developers

Aconex, the leading solution provider in cloud collaboration platform for the worldwide construction industry, has tied a knot with the Real Estate Developers’ Association of Singapore (REDAS) to implement Aconex Connected BIM and other collaboration technologies for forming a collaborative project surroundings for its member developers.

The motto of this alliance is to enhance collaboration, workflow management and productivity among architects, engineers, quantity surveyors, and contractors in the Singapore real estate value chain.

Now-days, several real estate value chain partners apply BIM to present electronic drawings to the Building and Construction Authority (BCA) for sanction. But they are unable to employ the functionalities & features of BIM as well as gain its complete advantages. The pilot project will facilitate these value chain partners to strongly control and distribute BIM models amid their whole project teams in accordance with pre-defined workflows.

The strategic alliance among REDAS and Aconex will facilitate using the cloud-based Aconex platform that unites multi-company teams to allow project-wide collaboration for handling all documents, drawings, BIM models, communications, and workflows.

Connected BIM expands the Aconex platform for dealing with BIM data and procedures for making sound collaboration connecting design and construction teams and surrendering to the owner.

This joint venture will make a sea change in revising existing method in the real estate and construction sector. With this pilot project, REDAS can employ leading cloud supported construction collaboration technique for 10 member developers.

The 10 member developers associated with this pilot project are Allgreen, Bukit Sembawang, CapitaLand, CDL, CEL, Far East Organization, Frasers Centrepoint, Guocoland, Keppel Land, and Wing Tai. Here each will recommend a particular live project to initiate the Connected BIM approach to identify and evade design clashes in the initial phase, lessen rework, speed up construction schedules, and handover secure, superior and more sustainable built assets.

Once the project is completed, a complete and perfect set of organized project information together with the model as well as all of the documentation connected to each of its objects, and an audit trail can be submitted to the owner for operation.

Designers for particular disciplines can generate and revise BIM models in their indigenous authoring tools and apply simple software plug-ins to upload them in the Aconex BIM Cloud. On the Aconex platform, all the team members involved with project ranging from other designers, engineers, consultants, contractors, subcontractors, and owners will be able to analyze, allocate, mark up, and contribute to model data at the object level.

Some handy BIM/VDC-associated technologies which can make a sea change in AEC Firms

The workflows of AEC firms are improved to a great extent with the implementation of building information modeling & virtual design and construction. Several upgraded techniques emerge out to transform 3d co-ordination process to a superior level.

The followings are some handy BIM/VDC-associated technology trends which facilitate the building team to design, build as well as operate buildings efficiently in the future course of time.

3D laser scanning: Lots of softwares contain less expensive field scanning techniques which perform through BIM models having perfect field information for construction sites. A scan is performed through the strong laser recording of the building structure that gathers the shape and look of a site. These conditions are transformed into a cloud of data points which are imported into a BIM model.

On a solo project, 30 minutes of scan time in the jobsite and 30 minutes of post-processing and uploading the point cloud into a Revit model can lead to saving of $30,000.

Model energy performance on the fly: With the emergence of new software tools, energy analysis of a building is executed throughout the conceptual design stage. Autodesk and Sefaira have launched various applications facilitating designers to accomplish energy study of early concepts on the fly. These applications compact the time required for assembling and crunching energy performance data for a long period. It facilitates the design teams to adapt their designs on the fly on the basis of the data.

Prefabrication will transform building delivery: Several Building Teams are applying BIM methods to collude with general contractors and construction managers to prefabricate and set up building components which range from mechanical equipment, plumbing infrastructure, and even complete restroom pods.

BIM makes the prefabrication process easy and smooth as the design become constructible in the model to be prefabricated and installed.

Data management: Some leading software companies like Assemble Systems and Panzura have built up cloud-based devices to manage, preserve, and distribute project data in a sophisticated way.

Computer-aided manufacturing: With the arrival of prefabrication and manufacturing processes like Lean construction, it opens savings and process efficiencies, the AEC are compelled to comply much the identical way computer-aided manufacturing changed manufacturing. Various CAM technologies together with BIM processes can deliver ready-to-install modules.
