Special services for one of our first customers!

Our client, Mota-Engil, currently the largest Portuguese construction company present in various markets worldwide, has awarded Strukturas the redesign project of an Overhead MSS originally not provided by us and which had been stored for several years in their yard in Poland.

Strukturas’ redesign introduced significant modifications to the MSS, including a hinge joint between the main girder and the front nose, allowing it to be used on plan view curved decks, the addition of a rear concreting support, which allows for the transportation of pre-assembled U-shaped reinforcement using electrical winches, and the supply of a hydraulically operated internal formwork.

Mota-Engil transported the MSS from Poland to Portugal, where it is currently being used in the construction of railway viaducts. The rebuilt MSS steel structure was done in Portugal. Mota-Engil gave a special attention to pre-assembly and testing both at the workshop and at their central yard, due to the MSS being stored in Poland for several years.

Strukturas has been supplying various bridge building equipment, including Formtravellers FT and Movable Scaffolding Systems MSS, to Mota-Engil for around 30 years. Our the first supply was made in 1994 of an Underslung MSS to the company, that was then called Engil and later included in the Mota group, giving rise to the current Mota-Engil.

TB Heubach Bridge demolition

Implenia, a leading construction services company, decided to use an Strukturas Movable Scaffolding System (MSS) Underslung for the demolition of existing concrete decks on the TB Heubach Bridge in Germany.
 
This same MSS will also be used for the construction of the bridge’s new TT section decks.

Deck demolition

The Strukturas MSS solution is particularly innovative because it allows the conversion of the MSS formwork from a box section, which is used during the demolition phase, to a TT section, which is used during the construction of the new bridge decks. This approach saves time and resources, making the construction process more efficient.
 
The challenging conditions on the job site made the assembly of the MSS particularly demanding, and the Strukturas MSS assembly team had to plan and execute the operation to the best of their ability.
