Full-featured – Versatile – Easy to learn
CCADPrecast is one of the world’s leading applications for 3D precast concrete design. Its comprehensive feature set, high level of automation, and ease of use ensure that our customers always benefit from a design process that minimizes costs and effort while delivering results of the highest quality. Virtually every CAD user worldwide works with or has worked with AutoCAD, which drastically reduces training requirements compared to other programs and also has a positive impact on data exchange with external resources, as this data is very likely to be submitted in an AutoCAD data format such as DWG or DXF. This data can be processed directly by CCAD Precast and does not need to be converted or even redrawn first. Stay up to date with market standards using CCAD Precast and don’t become a slave to another software solution.
Various modules are available for CCAD Precast, which can be flexibly installed to meet individual needs. Specifically, the following modules are available:
– Solid wall, sandwich wall, double wall, thermal wall (collectively referred to as CCADWall)
– Solid slab, hollow-core slab, precast slab, Pi slab (collectively referred to as CCAD slab)
– Structural members, facades (collectively referred to as CCADGCP)
– straight staircases, spiral staircases, custom staircases, stairwells (collectively referred to as CCADStair)
CCAD-Wall is the base module for processing precast walls in the IDAT software solution. Within this base module, additional modules are available for various types of precast walls. Currently, IDAT offers its customers four different wall modules for processing solid walls, double walls, sandwich walls, and thermal walls. Depending on the precast concrete plant’s product portfolio, these modules can be used individually or in combination.
The process of entering walls has already been simplified and automated as much as possible. The basic parameters of the building being edited can be defined using an internal floor management system. If a 2D template (DWG or DXF) is available, it can be used directly for data entry. Internal functions detect whether a wall is exterior or interior as it is being entered and automatically set the necessary parameters. Walls can be freely designed geometrically, and the effort required to enter openings, built-in components, or architectural details is reduced to a minimum.
For example, if you want to create additional reinforcement at the edges of an opening, the program can be configured so that any subsequent changes are automatically adjusted. This means that if the opening is moved later, the associated edge reinforcement is moved along with it. If the size of the opening is changed later, the reinforcement is automatically adjusted to the new dimensions.
The next step in wall processing is fully automated wall element generation. In this process, the base walls of the building model are automatically divided into wall elements based on specifications from the project data. The program automatically takes into account basic rules (such as dividing walls at joints whenever possible and avoiding divisions in the areas of openings and built-in components). Furthermore, all wall connections are generated, and the basic reinforcement for the wall is inserted. Of course, openings and built-in components are cut out for this purpose.
Changes can be made very easily at any stage of the planning process and are automatically incorporated into all existing plans. The creation of production and installation plans, as well as the generation of machine data for the CAD/CAM interface when needed, is fully automated. Upon request, the relevant billing data is also generated and made available in a separate database.
Thermal walls, in particular, involve specific details regarding the creation and management of insulation and shell connections. Here, IDAT offers comprehensive functionality that already incorporates the latest trends, such as the Kappema system (which is also used in the production of double walls). A range of state-of-the-art production lines for thermal walls, which produce not only the actual precast elements but also the insulation fully automatically, are operated using the IDAT wall module.
CCAD-Decke is the base module for analyzing precast concrete slabs in the IDAT software solution. Within this base module, additional modules are available for various types of precast slabs. Currently, IDAT offers its customers five different slab modules for designing solid slabs, precast slabs, ribbed slabs, hollow-core slabs, and Pi-slabs. These modules can be used individually or in combination, depending on the precast concrete plant’s product portfolio.
The process of entering ceiling data has already been simplified and automated as much as possible. The basic parameters of the building being edited can be defined using an internal floor management system. If a 2D template (DWG or DXF) is available, it can also be used directly for data entry.
First, the user must define the ceiling panel. They can do this either by drawing a closed polyline along the outer edges of the ceiling panel and later converting it into a ceiling panel, or by using the internal room detection feature, which automatically detects the room if walls are present on the corresponding floor.
A special dialog box now allows you to set the type-specific settings for the slab. This also involves selecting the required reinforcement, unless it has already been calculated and placed by one of the integrated structural analysis applications. The program automatically places edge supports based on the specifications in the project data. The same applies, if necessary, to any reinforcement protrusions or bending forms at the edges of the slab.
The slab is then divided into elements based on specifications from the project data (e.g., minimum and maximum slab width). The program automatically takes into account any existing openings in the slab and, if desired, generates corresponding replacement reinforcement. In this case, the basic reinforcement of the slab is, of course, cut out accordingly. Manual slab element division is also available.
Changes can be made very easily at any stage of the planning process and are automatically incorporated into all existing plans. The creation of production and installation plans, as well as the generation of machine data for the CAD/CAM interface when needed, is fully automated. Upon request, the relevant billing data is also generated and made available in a separate database.
CCAD Stairs is the module for designing precast concrete stairs. It designs straight or spiral stairs, as well as complete stairwells in conjunction with the corresponding wall and ceiling modules. Stairs can be designed either individually or within a building model, taking into account connection requirements to landings, ceilings, walls, or beams.
Straight staircases
To begin with, you only need to enter basic data such as the stair width and height. The program automatically generates a stair design proposal, which can then be edited directly and adjusted to the required parameters (number of risers, rise-to-run ratio, top and bottom lengths and heights, etc.). The result can be visually checked at any time in a 3D view window.
If the staircase is not designed as a freestanding structure but rather connected to an existing ceiling or landing, you need only specify the staircase width. The program calculates the required height automatically. In this case, the necessary connection details—such as brackets, including reinforcement—can also be automatically generated in the ceiling or landing upon request.
Throughout the planning process, the program monitors compliance with certain parameters. For example, the slope ratio can only be adjusted within specific logical ranges.
Spiral staircases
In addition to the stair width and height, the type (quarter-turn, half-turn, or double-turn) must be specified here. Information regarding the string lengths must also be provided.
Stairs can be fully reinforced using predefined reinforcement types. Three independent sections (base, flight, and top) are available for this purpose. The program can also handle three-dimensionally curved reinforcement positions (bars in the flight of spiral stairs).
Stairwells
This feature offers a very practical function: First, the number and height of the floors are defined in the project data. The program then automatically generates multiple views of the stairwell, providing the designer with a clear overview. Next, the landings and stairs are placed in the stairwell one after another. The standard stair input dialogs are available for this purpose. The program automatically monitors compliance with connection points between different stair runs and/or landings. This ensures, for example, that the bottom edge of the staircase is at the same height as the bottom edge of the adjacent landing. Once the planning is complete, the user can generate fully automated production plans for the stair runs and installation plans for the stairwells.
CCAD-GCP is the module for designing structural precast elements. This module enables the integrated design of precast concrete columns, beams, joists, and trusses. Another area covered by this module is geometrically complex facade elements. As with the other IDAT modules, this module offers the highest possible degree of automation, which significantly reduces design time.
Manufacture of precast concrete columns, including foundation reinforcement:
This is done via a special input dialog. Before that, you can choose whether to generate a single column or multiple identical columns at the nodes—based on a column grid that must be defined beforehand. Several options are available for the height of the columns. You can either enter the column height directly in the input dialog or set the column height to be the same as the building’s height. In the latter case, the program automatically calculates the building height based on the heights of all floors in the building model. The third option comes into play when you want to assemble a column from several individual parts, with breaks between floors. Here, you can vertically assemble the individual column parts using predefined connection details.
Foundation connection:
There are several options to choose from:
Placement of beams or joists
A dialog box is used to define the shape, dimensions, and basic reinforcement. Then, simply click on the two supports between which the member is to be created to generate the beam, including the support brackets. The program automatically calculates the required length of the beam. The program prompts you for the type and dimensions of the brackets directly while you are entering the beam. The cantilevers are linked to the beam’s position; if the elevation of a beam changes, all associated cantilevers are automatically repositioned. The cantilevers are automatically reinforced with various reinforcement types. Here, too, the IDAT-standard principle applies, whereby the reinforcement dimensions automatically adapt to the size of the cantilever.
Installation of large precast trusses
You can select the desired truss type from a catalog (profile, bracing, etc.) and set the free parameters. Then, similar to the beams, you select the two support columns, and the truss is generated with the correct orientation and length. The type of connection between the truss and the column (with or without a fork connection) is selected and automatically accounted for by the program.
Changes can be made very easily at any stage of the planning process and are automatically reflected in all existing plans. The creation of production and installation plans, as well as the generation of machine data for the CAD/CAM interface when needed, is fully automated. Upon request, the relevant billing data is also generated and made available in a separate database.
The IDAT program automatically generates the basic reinforcement for all precast elements (walls, slabs, stairs, columns, and beams, etc.). The reinforcement types are defined in advance in catalogs with their As-values. Using the integrated structural analysis applications, the required reinforcement is determined directly, and the reinforcement relevant to the precast element is indirectly recalculated.
The software’s comprehensive 3D capabilities naturally also apply to reinforcement. All reinforcement positions are generated and displayed in an element in their correct location. This is particularly important in connection with production automation, such as reinforcement laying robots, rebar bending and cutting machines, and mesh welding systems. The 3-dimensional location of the reinforcement is required for the correct control of these machines.
In addition to automatic rebar generation, rebar can of course also be edited manually. Furthermore, custom bend shapes or stirrups can be drawn as polylines within the precast concrete element and placed directly by specifying their diameter and spacing.
In addition, users have access to a wide range of parameterized functions for automatically generating and placing standard reinforcement. Examples include edge stirrups and column or lintel reinforcement, which minimize the effort required to generate these reinforcement elements.
All reinforcement behaves in a fully associative manner with respect to the member geometry. The reinforcement automatically adapts to the member’s geometry at all times. This applies to simple reinforcement such as reinforcing bars or mesh, as well as, for example, stirrups in a tapered beam. In such cases, even the stirrup heights are automatically adjusted to the geometry, including when the geometry changes.
Another aspect of reinforcement that the software also covers (to the extent that this is relevant for a precast concrete plant) is on-site reinforcement. This can also be created using parametric functions.
A key feature of the software is the fully automated creation and plotting of plans for production and the construction site. Depending on the type of precast element, various plan layouts are available for this purpose. These layouts may differ in appearance to accommodate the specific information requirements of the respective precast elements.
Generally, a production plan includes the following information by default:
The layout plan for the construction site is also generated automatically. The program determines the appropriate paper size based on the project size, the selected scale, and the available paper sizes for the plotter. The layout plan is then created according to the parameters set in the program configuration.
The following information is available:
The layout of the drawings can be customized. You can also specify the paper size for the drawings and whether they should be displayed in portrait or landscape orientation. If desired, the information from a fabrication drawing can also be distributed across multiple drawings: for example, a component drawing showing the part’s outline, a reinforcement drawing, and an installation drawing.
A major advantage of the AutoCAD Architecture base software is the ability to fully customize the display settings for individual objects. In practice, this means that a wall element, for example, can be displayed and labeled in completely different ways across the various sections of the program (model area, fabrication plan, layout plan, etc.). This, in turn, allows users to freely customize the appearance of their objects.
The key point here is that the object is displayed directly in all views, rather than a copy being created. This allows you to modify the objects in any view and on any drawing. Any changes are then automatically applied to all other drawings.
The software really shines when it comes to making changes after the fact. During development, special care was taken to ensure that changes to the project can be made quickly, easily, and reliably.
Changes can be made equally easily in both the model and the plan view. If you move an opening in the model, this change is automatically applied to the relevant production plan and the installation plan. However, you can also make changes directly in the production plan or even in the installation plan. In this case, too, the change is applied automatically.
This level of functionality is unparalleled.
A major problem in the production of precast concrete components is collisions between reinforcing bars and/or embedded parts that go undetected during the planning phase. This is particularly true for automated systems that use robots for placing reinforcing bars or for mesh welding systems.
Problems can also arise with double-wall construction—specifically when the inner shell is embedded into the outer shell and electrical outlets are located at the positions of the grid beams in the opposite shell.
To address these issues before production begins, the software includes comprehensive collision detection features. These features check all embedded reinforcements and built-in components for potential collisions. If a collision is detected, the affected areas are highlighted in color, and the user can resolve the collision either within the model or directly on the production plan.
Since the software fully supports BIM technology and manages all precast elements in a project within a single building model, it can also perform functions that span multiple precast elements.
Here are a few examples of how different prefabricated components are affected:
In addition, collisions between components are automatically detected and handled accordingly. Here are two examples:
All of these features and checks actively help prevent planning errors and significantly improve the planning process.
A major challenge in developing a CAD solution for precast concrete plants is ensuring the software has the flexibility needed to adapt to customers’ varying requirements. The software must adapt to the plant, not the other way around.
The groundwork must be laid right at the start of the development process. Applications must remain easy and quick to customize, even after serving a thousand customers. IDAT has found an excellent solution for this challenge. It has succeeded in significantly reducing the effort required to personalize and configure systems for new customers while simultaneously empowering customers to manage their own systems.
Unlike other providers, IDAT encourages its customers to be self-reliant. They can save a significant amount of money by learning to make important configuration changes on their own.
You'll quickly come to appreciate this degree of independence.
The term Building Information Modeling (BIM) refers to the simulation of a complete building design using software. This involves creating a virtual building model from which all necessary data for the construction, operation, and maintenance of the building can be derived. The major advantage of this type of planning is that changes or additions to the project are immediately available to all stakeholders, allowing them to adjust their specialized plans accordingly. The wealth of information that can be stored in such a model is by no means limited to structural data for constructing the building. Data covering the entire lifecycle of a building, such as operating costs, can also be included. RevitPrecastLink opens the door for precast concrete manufacturers to integrate the production level into a BIM process. On the one hand, it ensures that users will continue to be considered for future projects and tenders (since the technical capability to participate in a BIM planning process is now often a prerequisite for contract award); on the other hand, it opens up entirely new possibilities for project and quality monitoring.
