CCAD Precast

The software CCAD is one of the world market leading programs for 3-dimensional design of precast concrete parts. The complete functional range, the high level of automation and the easy handling – these are the key benefits for our users to get a cost-optimized design process with the best quality results. Nearly every CAD designer in the world works with AutoCAD. Compared to other programs this reduces the effort of training, raises the user acceptance and affects the data exchange with other people and departments positively because data exchange must be mostly done via AutoCAD formats DWG or DXF. These data could be used directly by CCAD. There is no need to emulate data or redraw in the worst case. Stay close to the market standards and don´t make yourself a slave of other software solutions.

Different modules are available for CCAD. They could be purchased and installed flexible along with your personal demands. The following modules are available:

– Solid Wall, Sandwich Wall, Double Wall, Thermo Wall (CCADWall)

– Solid Slab, Hollowcore Slab, Girder Slab, Double T Slab (CCADSlab)

– Columns, Beams, Facades (CCADGCP)

– Straight Stairs, Winding Stairs, Special Stairs, Staircases (CCADStair)

CCAD Wall

CCAD-Wall is the basic module for editing Precast concrete walls in the IDAT software solution. Other modules are available within this basic module for different types of precast wall units. IDAT currently offers customers four different wall modules for editing solid walls, double walls, sandwich walls and thermal walls. These modules can be used individually or in combination depending on the range of products manufactured by the concrete precasting plant.

The entry of wall data is made easy and automated wherever possible. The basic parameters for the building to be edited can be defined via internal floor management. If a 2D template (DWG or DXF file) is available, this can be used to input data directly. Internal functions recognize while the data is being entered whether an external or internal wall is involved and set the required parameters automatically. As any geometric designs can be used for the walls, the time and effort involved in entering data on openings, built-in parts or architectural details is reduced to a minimum.

If you want to generate additional Reinforcements on the edges of openings, for example, the program can be configured so that this subsequent change is automatically incorporated. This means that if the opening is moved subsequently, the associated reinforced edges are moved as well. If the size of an opening is changed at a later stage, the reinforcements will be automatically adjusted in line with the new dimensions.

The next stage in developing the walls is fully automatic wall prefabrication. At this point, the basic walls of the building model are broken down into prefabricated wall units in a fully automated process using the project data specifications. The program automatically takes into account the basic guideline parameters (such as division preferably into wall joints and no division in the area of openings and built-in parts). Furthermore, all wall connections are generated and the basic wall reinforcements inserted. Openings and built-in parts are naturally cut out.

Subsequent modifications can be made extremely easily at any planning stage and are automatically incorporated into all existing plans. The generation of construction and layout plans and, where required, machine data for the CAD/CAM interface are fully automatic. The relevant accounting data can also be generated on request and made available in a separate database.

Especially for the design of insulated double walls IDAT offers a very high level of functionality. The special requirements in handling of insulation and formwork connections are fully implemented in the IDAT wall module. Also, the latest developments like the Kappema-System are already included. A couple of state of the art production facilities for insulated double walls are already managed by IDAT software.

CCAD Slab

CCAD-Slab is the basic module for editing prefabricated ceilings in the IDAT software solution. Other modules are available within this basic module for different types of prefabricated ceiling. IDAT currently offers its customers five different ceiling modules for editing solid ceilings, prefabricated ceilings, ribbed ceilings, hollow ceilings and PI slabs. These modules can be used individually or in combination depending on the range of products manufactured by the concrete precasting plant.

The entry of ceiling data is made easy and automated wherever possible. The basic parameters for the building to be edited can be defined via internal floor management. If a 2D template (DWG or DXF file) is available, this can be used to input data directly.

First, the user needs to define the ceiling panel. This can be done either by drawing a single polyline along the outer edges of the ceiling panel and converting this into a ceiling panel at a later stage or by using internal room recognition, which, if walls have been provided on the respective floor, automatically recognizes the room.

The type-specific settings for the ceiling can now be set in a special dialog. The required reinforcements are also selected for this unless this has already been calculated from one of the structural analysis applications in use and inserted. Edge supports are set automatically by the program using the project data specifications. The same also applies if any steel projections or bending molds are required on the ceiling edges.

The ceiling panel is then prefabricated using the project data specifications (e.g. minimum and maximum ceiling width). The program automatically takes into account any existing ceiling openings and generates the respective replacement reinforcements on request. Naturally, the basic reinforcements for the ceiling are in this case cut out accordingly. Manual ceiling prefabrication is also available.

Subsequent modifications can be made extremely easily any planning stage and are automatically incorporated into all existing plans. The generation of construction and layout plans and, where required, machine data for the CAD/CAM interface are fully automatic. The relevant accounting data can also be generated on request and made available in a separate database.

Bubbledeck:

IDAT CCAD-Slab also supports the Bubbledeck system. In this special slab system plastic bubbles are arranged on top of a precast half slab to reduce weight and safe concrete. The bubbles must be placed under consideration of the reinforcement mesh positions what CCAD-Slab automatically supports. Also, special conditions on the plate edges will automatically be considered and the bubble positions and numbers are shown on the shop drawings. The bubble numbers are also exported in the bill of materials.

CCAD-GCP

CCAD-GCP is the module for editing precast structural units. This module makes the integrated planning of precast concrete supports, girders, beams and trusses possible. Prefabricated facades featuring complex geometric forms are another area covered by this module. As with the other IDAT modules, the highest possible degree of automation is available here, thereby shortening planning time considerably.

Production of precast concrete beams incl. basic reinforcements:

This is done using a special input dialog. You can choose in advance whether to generate individual beams or several beams of the same shape on the points of intersection with the help of a support grid that needs to be defined in a previous step. Several options are available for the height of the beams. You can either enter the height of the beam directly into the input dialog or select the height of the beam as the same height as the building. In the latter case, the program calculates the height of the building on the basis of the height of all the floors in the building model. The third alternative comes into question in cases where you wish to assemble a beam on a floor by floor basis using multiple individual units. The individual beams can be assembled based on the corresponding predefined connection details.

Foundation connection:

Several options are available here:

  • Popular screw or welding connections (e.g., support shoe) from predefined catalogs from different suppliers such as Halfen, Pfeifer or Peikko can be positioned directly at the base of the support.
  • A separate function generates an adjoining base for the support.
  • Alternatively, sleeve foundations or foundation pads can be used; these are available as separate precast units.

Positioning of beams or girders

The shape, dimensions and basic reinforcements are defined in a dialog box. Once this is complete, simply click on the two supports between which the component is to be inserted. This, in turn, triggers the beam and support bracket to be generated. The program automatically calculates the required length of the beam. You will be asked to provide details of type and dimensions when entering the beam specifications. The brackets are linked to the position of the beam. If the elevation of a beam changes, all related brackets are then moved automatically. The brackets are automatically reinforced with different types of reinforcements. The standard IDAT principle, whereby the dimensions of the reinforcements are automatically adjusted to the size of the brackets, also applies here.

Positioning of large precast trusses

The required truss type (profile, reinforcements, etc.) can be selected from a catalog and any necessary parameters set. You then select (as in the case of beams) the two bearing supports, and the trusses will be inserted in the correct position and at the proper length. The program automatically selects and takes into account the nature of the connection between trusses and supports (with or without straddle mounting).

Subsequent modifications can be made extremely easily any planning stage and are automatically incorporated into all existing plans. The generation of construction and layout plans and, where required, machine data for the CAD/CAM interface are fully automatic. The relevant accounting data can also be generated on request and made available in a separate database.

CCAD-Stair

CCAD-Stair is the module for editing precast concrete stairs. It plans not only straight or spiral stairs, but also complete staircases in combination with the respective wall and ceiling modules. Staircases can be planned both individually as well as within a building module, with consideration given for connection conditions on landings, ceilings, walls or beams.

Straight stairs:

To begin with, only the basic data such as stair width and height needs to be entered. The program will automatically suggest a default staircase, which can then be edited directly and adjusted to the required parameters (number of gradients, rise-to-run ratio, head height/foot length etc.). The results can be checked visually at any time in a 3D viewer.

If the stairs are generated as free-standing and not connected to an existing ceiling or landing, only the width of the staircase needs to be specified. The program then calculates the required height. In this case, the required connection details such as brackets, including reinforcements, are generated automatically.

The program monitors compliance with certain parameters throughout the planning process. For instance, the rise-to-run ratio can only be changed within certain logical areas.

Winding Stairs

In this case, in addition to the stair width and height, the type (quarter spiral, half spiral or double spiral) must be indicated. Details of flange lengths must also be specified.

The stairs can be completely reinforced using predefined reinforcement types. Three independent areas (foot of the stairs, stair flight, and stairhead) are available here. The program can also process 3D curved reinforcement positions (stair rods in the case of spiral staircases).

Staircases

A practical function is available here: Firstly, the number and height of the floors are defined on the basis of the project data. The program then automatically draws multiple views of the staircase to provide the planner with an excellent overview. The landings and stairs are subsequently positioned in succession in the staircase. The standard stair input dialog is again available for this purpose. The program automatically monitors to ensure compliance with the points of intersection between various flights of stairs and/or landings. This guarantees, for example, that the underside of the stairs is at the same height as the underside of the connecting landing. Once planning has been completed, the user can automatically generate production plans for the flights of stairs and layout plans for the staircases.

CAMData

IDAT CAMData is an optional function for CCAD. It allows the user to generate machine data files of each precast panel for automatic control of machines and robots in the manufacturing plant. IDAT CAMData is available for the market standards Unitechnik, PXML and BIBM which is used by most of the existing machine manufacturers. Another interface types can be developed by demand individually. Please ask us if necessary. CAMData is always necessary when machines like plotters, laser projectors, steel cut & bending machines etc. should be managed automatically.

MESHData

IDAT MESHData is an optional function for CCAD. It is specially made for clients who use a mesh welding machine and want to control this via machine files from the CAD/BIM design. IDAT MESHData is automatically generating individual reinforcement meshes for every panel/part which was generated in CCAD along predefined rules for the used mesh welding machine. So, for example, the program check possible bar diameters, minimal bar distances, maximal knot thickness and much more. The user can individually change the mesh but IDAT MESHData always checks in real time if the changes are fitting the rules of the machine. IDAT MESHData already includes CAMData what is generally necessary to generate machine files. So with the purchase of MESHData it is possible to manage other machines via CCAD as well.

ISOData

IDAT ISOData is an optional function for CCAD. It is specially made for the planning and design of insulated precast concrete walls likeSandwich Walls and Thermo Walls (Insulated Double Walls). IDAT ISOData is preparing the whole insulation parts of a panel and also able to export this data for machines. The function considers predefined raw sizes of insulation and places it in the panel with offcut optimization over the panel or the whole floor. If glassfibre connectors are used so ISOData calculates the right number and positions automatically. Location and size of possible openings will be considered. The position of the glassfibre connectors will be checked against collisions with the reinforcement in the two formworks what is especially important for the production of Thermo Walls where the connectors of the first formwork will be plunged into the fresh concrete of the second one and collisions with the reinforcement can cause damages of the connector. ISOData is able to generate files for cutting and drilling machines for the premanufacturing of insulation parts.
