Bridges & Tunnels
Reinforced concrete and steel bridges, viaducts, tunnel excavation and lining — end-to-end responsibility for structures.
What we do
Piled and shallow foundations, columns and pier caps, precast beam production and erection, in-situ deck, steel composite deck, tunnel excavation, shotcrete and final lining, waterproofing and expansion joints.
How we work
Because geometric tolerances are tight on structures, formwork and reinforcement drawings are re-checked against site conditions before fabrication. Precast beam erection is planned against crane capacity and ground bearing calculations. In tunnels, each advance is tied to a geological observation record at the face.
Standards
Concrete design and reinforcement detailing follow EN 1992 and steel fabrication EN 1090 practice; tunnel support classes are applied according to in-situ geological classification.
Piling rigs, mobile and crawler cranes, climbing and tunnel formwork systems, shotcrete robots, grouting equipment. Precast elements are produced in a controlled yard; each unit passes visual and dimensional acceptance before erection.
Work at height and lifting operations are subject to separate risk assessment; a lift plan is written for every erection. In tunnels, ventilation, gas monitoring and escape drills are continuous.
Prequalification & survey
We review the tender documents, visit the site and put the existing conditions and the client's expectations in writing.
Quantities & proposal
We produce item-based quantities and present a proposal with a clearly defined scope; exclusions are stated explicitly.
Planning & permits
A single programme, the resource plan and required permit processes are set up.
Execution
The site is mobilized; infrastructure and buildings proceed on one schedule and are reported regularly.
Handover
The snag list is closed and as-built documents are handed over.
Do you prefer precast or in-situ construction?
Span, site access and programme decide. Precast beams shorten the schedule on repetitive spans; in-situ suits structures with difficult access or varying geometry.
Can you strengthen an existing bridge without demolition?
In most cases yes. After a load capacity assessment, capacity can be increased by jacketing, added reinforcement, carbon fibre strengthening or bearing replacement.
