2 What we do is an independent software house. offers specialised solutions for bridge engineers. geodes/geocon/assemcon support geometry control for pre-cast segmental bridge construction. crosswind supports wind dynamic analyses for long-span and high-rise structures. assemcon development supported by the Austrian Research Council (FFG). 2

3 Who we are consists of a team of dedicated software and bridge engineers. directors have a strong background in research & development, as well as in hands-on engineering project execution. Martin Pircher, PhD Paul Pieringer, PhD 3

4 Geometry control geodes Geometry modeller for segmental bridges. geocon assemcon Geometry control during segment production in the casting yard. Geometry control during bridge assembly on the construction site. 4

5 geodes geodes assists in defining segmental bridges with a great degree of detail and precision. 5

6 geodes Deck geometry based on road or rail alignments using first principles in plan view and elevation. Alignements consist of straights, clothoids, arcs in plan; and arcs and parabulas in elevation. Unlimited number of alignments. Secondary alignments at variable 3D offsets possible. Selected locations along axes for connection with abutments, piers etc. Alternative input using pre-processed alignment data instead of first principle alignments. 6

7 geodes Parametric cross-sections with variable measurements along alignment. Cross-sections to adapt in geometry according to the position along the alignment. Alignment intersection with cross-section plane. Control points for subsequent geometry control in geocon. 7

8 geodes Segments: match-cast segments, pier segments, cast in-situ segments, wet joints etc. Each segment can be defined to great detail depending on segment type. Joints can be at free angles to alignment in plan and elevation. Modelling of diaphragms or blisters etc. Fixed length, or adaptive segment length. Match-casting against one other segment plus bulkhead, or conjugate segments at both sides. 8

9 geodes Segment groups defined for typical segment sequences (e.g. typical cantilevers, typical spans etc.). Segment groups are placed on alignments to form the bridge structure. Individual segments can be placed as a tangent or secant to the alignment (or transition between the two). 9

10 geocon geocon is used at casting yards to support geometry control of pre-cast segments in short-line match-casting. 10

11 geocon geocon supports setting out of casting cells. Adjustment of conjugate segments to achieve desired deck geometry. Correction of casting errors surveyed in previous segments. 11

12 geocon Correction of casting errors using a novel mathematical approach. Corrections can be distributed over several segments if required. No limitations of the number of control points. Control points can be placed anywhere on the crosssection; and can be placed anywhere within the segment. Innovative algorithm provides instant feedback and optimum results. 12

13 geocon Horizontal match-casting typical for bridge decks. Vertical match-casting for piers or pylons also supported. Visualisation of Nipigon bridge in Canada. Match-casting of pylons to be supported by geocon. 13

14 geocon Optional functionality to support management of casting yards. Unlimited number of casting cells. Unlimited number of survey stations. Input of casting yard layout including positions of casting cells and survey stations. Tracking of casting yard layout in case of repositioning of casting cells or survey stations. Book keeping of which segments are cast in which casting cells, and which casting cells are occupied and which ones are free. 14

15 assemcon assemcon is used on the construction site to control the bridge geometry during assembly. 15

16 assemcon assemcon assists in the assembly of pre-cast segments at the construction site. Setting-out of starter segments. Geometry forecasts. Integration of segment-to-segment monitoring data. Optimisation of shims or other corrective measures. Consideration of as-cast data, pre-camber and construction sequence. Book-keeping of as-built geometry, and geometry evolution throughout construction. 16

17 Software Open architecture allows for compatibility with other software platforms. Cut & paste of input and results tables to Excel or other spreadsheet software. Spreadsheet data can be pasted directly into input screens. Automated report output in table or pdf format. All geometry data can be exported to.dxf format for further processing in CAD packages. 17
