We buildwhat buildsbridges.
Launching gantries, formwork and shoring, post-tensioning and heavy steel — engineered, manufactured and commissioned by one team, for infrastructure across South Asia.

So we start at the other end. Before a price is put on anything, we model the erection cycle against your span arrangement, your possession windows and your crew, and we tell you what the machine will actually achieve.
Then we build the machine that honours the number — in our own works, checked by an engineer who did not design it.
How a scheme is builtFour divisions. One contract.
Most projects need two or three of these at once, and most suppliers can only sell one. Bringing them under a single project structure is the whole point of the company.
The cycle
A viaduct is one loop, repeated a hundred and eighty times.
Everything IBEC designs is aimed at taking hours out of this four-stage loop. A day a span across a long corridor is half a year of programme.

The method is the product.
A gantry is a lump of steel until somebody has proved it can put a span up in three days on your alignment, in your possession windows, with your crew. That proof is the thing IBEC actually sells. The steel is how we honour it.
- 011 – 3 weeks
Method study
Before anything is priced, we work out how the structure gets built and what that costs in days.
We take the general arrangement, the span table, the site constraints and the programme, and produce two or three viable erection methods with an honest cycle time against each. Most of the value in a temporary works package is decided here — a method that saves a day a span across 180 spans is worth more than any discount on the steel.
Deliverables
- Comparative method statement, 2 – 3 options
- Cycle-time model per option
- Preliminary equipment schedule
- Programme impact and risk register
- 023 – 6 weeks
Scheme design
The chosen method becomes a machine: geometry, loads, load paths, reactions handed back to the permanent works designer.
Global analysis is built in the frame model at the same time as the erection sequence, so every stage of the launch is a load case rather than an afterthought. The reactions that the temporary works will impose on piers, pier caps and the deck are issued to the permanent works designer early enough for them to matter.
Deliverables
- General arrangement drawings
- Global structural model and stage analysis
- Reaction schedule to the permanent works designer
- Interface drawings for pier brackets and supports
- 036 – 12 weeks
Detailed design & independent check
Every member, connection, pin, cylinder and control interlock is designed, then checked by an engineer who did not design it.
Detailed design covers the structure, the mechanical systems, the hydraulics and the control logic together. A category III independent check is run in parallel by an engineer outside the project team, working from the brief rather than from the design, in line with BS 5975 practice. Nothing is released for fabrication until the check certificate is signed.
Deliverables
- Full calculation package
- Category III independent check certificate
- Fabrication drawings and weld procedures
- Hydraulic and electrical schematics
- 0412 – 24 weeks
Manufacture & trial assembly
Built at our own works, assembled complete, surveyed against the model and function-tested before it is allowed on a truck.
Material is traced from mill certificate to erected piece. The machine is assembled in the works to the extent the bay allows, dimensionally surveyed against the design model, and put through a full functional test of its hydraulics and controls with the client present. Problems found here cost hours; the same problems found on site cost weeks.
Deliverables
- Material traceability and test certificates
- Trial assembly dimensional survey report
- Functional test record, witnessed
- Erection, operation and maintenance manuals
- 05First 3 spans
Commissioning & site support
Our crew erects it, load tests it, runs the first spans with your team and stays until the cycle time is being hit.
IBEC supervisors run the first three erection cycles alongside the contractor crew, then hand over against a written competence check. A load test with instrumented deflection measurement is performed before the first production span. Spares and a response commitment follow the machine for the life of the contract.
Deliverables
- Erection and commissioning record
- Instrumented load test report
- Operator training and competence sign-off
- Spares schedule and support agreement
Delivered, measured, and written down.

Two works, five offices, sites in eleven states.
Equipment is only as good as the distance between it and the engineer who designed it. Both works are within a day's drive of the design centre, and every site is within a day of a works.
