It is well-known that the choice of methods to accomplish a civil engineering task depends on the complexity of the major components of the structure. Presently, the most common types of bridges are: monolithic or composite on roads and metal or pre-cast concrete on railways. Structure reconstruction on railways requires working during scheduled rail closure time slots. On roads there is usually more flexibility to this as it is much easier to arrange by-passes or traffic control schemes allowing performance the works. It is this major discrepancy that makes bridge designs fundamentally different.

The plant, building machinery, equipment and tacking employed by TILTS allow performing building and reconstruction works of bridges and overpasses of any size and complexity in very short time periods, with practically no impediment the constant flow traffic.

The specialist boring machine unit BAUER BG-15 allows to install hammer-drilled piles and piers of 620/880/1300 mm in diameter up to 40 metres deep. The machine is also capable of performing intensive drilling operations in any type of soil. In addition to that, the capabilities of the drilling unit are such that it allows performance of drilling operations in very strictly controlled conditions such as near sites of historical interest or protected buildings, that is in the areas where the dynamic driving of piles is impossible. The company can also erect tilted piers with a slope up to 14 degrees.

In January 2002, TILTS has installed the latest automated concrete plant SCHWING-Stetter (Germany), with the capacity of 30m3 of any type (up to B60) concrete per hour.
