Service 1: 3D Modelling & Design/ Shop Drawings
Complete 3D model without major clash
In our services for industrial plants, all details are combined in only ONE 3D MODEL including equipment, piping, duct, architectural details, foundation, upper structure, concrete, rebar, embedded steel part, pre-stress cable, structural steel, cladding, metalwork, bolt, nut, etc.
This method will allow all project’s stakeholders to foresee all majors clashes, in order to find the best solutions in the engineering phase, so that most of the difficulties in the construction phase will be eliminated in advance to ensure the Quality, Time Schedule and Cost of the projects.
High quality drawings
Drawings are generated directly from the 3D model with the highest quality to ensure no different parameter of one object in all drawings.
3D views and details of the complicated structures can be shown in the 2D drawings, in order to help all stakeholders to implement their works in easier way.
Different parameters of rebar can be presented by different color in the drawings, in order to facilitate in the best way for the cut & bend in the workshop and installation work on site.
Correct bar bending schedule (BBS) without any mistake
The bar bending schedule (BBS) is automatically generated & linked with the 3D model to achieve the absolutely correctness level without any mistake of rebar parameters (mark, number, weight, length, shape, dimensions, etc.), following any required standards. We can export the rebar’s parameters in the BBS to .bvb, .abs, bvbs & ifc files, create barcode and import to the cut & bend machines for automatic rebar fabrication in the OFF SITE plants.
The below BBS is generated from 3D Tekla model, following BS 8666-2005: BBS – Bar Bending Schedule according to BS 8666-2005:
High precise level for all details
The accurate data and correct bar bending schedule without mistake ensures less errors for cut and bend works in the prefabrication yards as well as the rebar installation in the construction sites, in order to optimize the effort for the project.
Quantities control
The quantities can be easily generated from 3D/BIM model with 100% correctness level for specific area with each rebar type.
Typical 3D/ BIM rebar detailing projects
iCEB has been providing 3D/BIM rebar modeling services to clients worldwide, including in Australia, New Zealand, Europe, the US, South America, and Asia. Below are some example projects:
The Modular Rebar Solution is a highly professional method that iCEB plans to prioritize in its business development over the next few years. In this method, structures (foundation, starter bars, walls, columns, beams, slabs, etc.) are divided into typical elements to be fabricated in the workshop, transported to the site by truck, and primarily installed using cranes at the construction site.
iCEB Solutions Vietnam has been providing 3D rebar modeling and shop drawings for large-scale bridge projects in Australia & New Zealand, utilizing the precast construction method. The inputs for these projects are 2D design drawings. The outputs include 3D models of the bridges, including beams, piers, crossheads, and other elements. These models ensure clash-free integration of all components, consist of rebars, anchor bolts, prestress cables, ducts, and embedded steel parts. Additionally, color drawings, bar bending schedules (BBS), and concrete quantities are generated from the 3D models.
The parametric modeling method is applied to this project, with 80% of the work, including concrete, rebar, and prestress tendons, being completed in Grasshopper software before being transferred to Tekla Structures. By consolidating all details into a single model, many major clashes, especially between prestress tendons and rebars, are identified and resolved. The bar bending schedules (BBS) are generated automatically from the 3D model according to BS8666 standards. The Bvbs file is sent to the off-site plant for digital fabrication. Notably, the contractor uses the 3D model directly for rebar installation at the construction site, eliminating the need for traditional drawings.
This residential and commercial building comprises 26 floors with two basements, utilizing piling foundations. A key highlight of this project is the successful installation of a large transfer beam (3 meters in height, 20 meters in span, and with very high rebar density) by the rebar fixer without any difficulty or need for technical clarification, thanks to the application of 3D/BIM technology. Additionally, clash-free design is applied to all main elements of the building, including piles, foundations, columns, walls, beams, slabs, stairs, and more, providing excellent input for the rebar fixers to perform their tasks efficiently at the construction site.
In our services for industrial plants, all details are combined into a single 3D model, including equipment, piping, ducts, architectural details, foundation, upper structure, concrete, rebar, embedded steel parts, prestress cables, structural steel, cladding, metalwork, bolts, nuts, and more. The highlight of this heavily loaded building is the concrete curved beams with very high rebar density, along with large embedded steel parts for equipment. Additionally, there are numerous large anchor bolts at the top of the concrete columns, positioned clash-free with D32mm rebar to connect the steel columns above. The work is significantly easier for the contractor on-site with the completed 3D model.
The foundation diameter is 50 meters, supporting the equipment or structural steel above. The 40mm diameter rebars, with very high density, are developed from the center to the outer perimeter of the foundation. At the foundation’s perimeter, large diameter anchor bolts are positioned without interfering with the rebar to connect the tank above. Due to the complexity of the details, the design was clarified and adjusted several times during the detailing phase to facilitate the contractor’s work at the construction site. Ultimately, we achieved a clash-free model for all elements of the foundation, including the high-density rebars, starter bars, and large anchor bolts to connect to the equipment or structural steel above.
The silo has a height of 100 meters and a diameter of 20 meters. The wall thickness is 0.8 meters, reinforced with prestressed cables and a high density of rebar. We offer professional 3D/BIM civil and structural steel engineering and detailing for silos, providing all details in a single model. It is happy to see how a well-designed model facilitates smooth operations at the construction site.
The crusher is approximately 15 meters deep from ground level, with a bottom slab and wall thickness of 1.0 meter. The hopper has a complex geometry, featuring four faces with different slopes. Thick lining steel plates are embedded in the concrete hoppers at various points, ensuring they do not clash with the high-density rebars.
The concrete walls for the basements of a high-rise building, measuring 146 meters in length, 40 meters in width, and 30 meters in height, are divided into standard diagram walls with dimensions of 1.2 meters in thickness, 6.2 meters in width, and 30 meters in height. iCEB developed automation tools to generate the 3D model and the drawings automatically for these diagram walls.
