Precast Element Engineering
Precast beams, columns, slabs and wall panels with prestress analysis, lifting checks and connection verification for the factory.
The tools
Products for Concrete Design & Rebar Detailing Software
Design and verify the concrete first, then detail the reinforcement and schedule the bars.
Design and verification

STRAP
RC frame analysis and code design — beams, columns, walls and slabs to codes like ACI 318 and IS 456.

IDEA StatiCa Concrete
Code-checks for concrete details — corbels, dapped ends, anchorage zones and cross-sections, reinforced or prestressed.
Detail and schedule

COMOSYS 2026
BIM rebar detailing — 3D reinforcement models and automated bar bending schedules from the verified design.
Answered
Questions engineers ask us.
3D steel detailing software built for automation
You model the structure once in 3D. IntelliConnect places library connections; IntelliClone repeats detailed zones across similar framing. COMCLASH watches for clashes and AutoAdjust re-fits members when geometry moves. Shop drawings, schedules and NC files come off that same model.
Auto-generate fabrication drawings from a 3D model
COMOSYS generates shop, assembly and GA drawings straight from the 3D model. Plans, elevations, sections and detail sheets carry title blocks, dimensions and BOM tables. When the design changes, drawings of macro-placed elements regenerate automatically. Nothing gets drafted twice.
CNC/NC file generation for steel fabrication
NC files generate from the same 3D model as the drawings. Every member, plate and bolt is already resolved in that model. COMCLASH clears interferences before anything reaches the machine. The detail that was checked is the detail the line fabricates.
Generate Bar Bending Schedules (BBS) from a model
The rebar module reads the 3D rebar model and writes the BBS. Bar marks, shapes, lengths, weights and totals format to Indian practice. Update macro-placed reinforcement and the schedule regenerates on its own. Manually placed bars refresh one by one.
IS 800 steel detailing and shop drawings
COMOSYS designs and details hot-rolled steel to IS 800:2007. AISC and EN 1993 run in the same environment when needed. Shop drawings, connection details, erection drawings and BOMs all generate from the model. Output comes formatted for Indian fabrication practice, ready for the shop.
Seismic analysis of a 15-storey RCC tower
STRAP runs Modal analysis to find the tower's periods. Response Spectrum or Time History then carries the seismic case. P-Delta picks up second-order effects in tall frames. Concrete design checks beams, columns, walls and slabs to codes like IS 456.
Composite floor design with shear studs
STRAP carries composite steel-concrete design alongside its hot-rolled and cold-formed checks. The floor sits in the same 3D model as the rest of the structure. Beams run through the steel design module against the selected code. Graphic and tabular output shows the governing force envelopes.
Structural analysis software for industrial facilities
STRAP handles industrial structures in one model: frames, slabs, walls and cables. Load generation covers wind, seismic, snow, crane and moving loads. Analysis runs static, modal, P-Delta and staged construction cases. Members then design to hot-rolled, cold-formed and concrete codes in the same run.
