The method involves projecting layout information on a working surface of a construction work. The projected layout information is obtained from a model, such as a Building Information Model (BIM), of a portion at least of the construction work. It includes first graphical information depicting a reference feature visible on the working surface, and second graphical information designating locations for installation of construction elements. The locations are linked, in the model, to the reference feature depicted by the first graphical information. In response to a user action of selecting the first graphical information and a geometric transformation, the projected first graphical information and second graphical information are shifted together in accordance with the selected transformation.

The damping device comprises an interconnecting structure between cables of a group of at least three cables of the suspension system which extend substantially in one and the same suspension plane P. The interconnecting structure has, outside the plane P, at least one bearing point for an energy dissipating element arranged so as to develop a damping force in response to a movement of one of the cables of the group relative to the other cables of the group in a direction perpendicular to the suspension plane.

The method is for protecting the end of a cable made of a plurality of parallel tendons () anchored using a block () having a front side, a rear side and channels () extending between the front and rear sides. Each tendon of the cable is held in a respective channel of the anchor block with a blocking member (). The method comprises performing a first phase of injecting protective material () into at least some of the channels of the anchor block. A chamber () is formed on at least one side of the anchor block () so as to contain portions of the plurality of tendons. A second phase of injecting protective material () into the chamber () is then performed.

A method of construction of a civil engineering structure that includes first and second superimposed components is described. According to one embodiment of the method: the second component is positioned beneath a fixed lifting structure that includes a lifting device, the second component is lifted using the lifting device, the first component is positioned beneath the fixed lifting structure substantially below the second component, and the second component is substantially placed on the first component using the lifting device, while the second component remains substantially in place.

The invention proposes a system for obtaining information relating to a pipe () conveying a flow of fluid (), and/or relating to the fluid. This system comprises a module () comprising means () of acquiring data, subsequent analysis of which makes it possible to obtain information relating to the pipe and/or the fluid, and means () of storing the data which said data acquisition means acquire, the self-contained module being arranged to be pushed by the fluid flow after being introduced into the pipe. It also comprises a mechanical link () which is connected to the self-contained module and accessible from outside the pipe.

The invention provides a method for the transport of a civil engineering structure in an aquatic medium. According to this method: at least one float is associated with the civil engineering structure in such a way as to ensure that the said civil engineering structure floats stably in an aquatic medium, the said float surrounding the civil engineering structure and a bottom portion of the civil engineering structure extending below the said float, and the civil engineering structure and the associated float are caused to move in the aquatic medium to a desired position.

A method for assembly of a stay includes a series of steps that include connecting in the vicinity of an anchoring zone, a new group of N reinforcements to a shuttle located within the sheath of a stay to be installed. The shuttle is driven towards another anchoring zone by means of driving and guiding means. When the shuttle has arrived substantially in the vicinity of the anchoring zone, and as long as entangling is detected between the driving and guiding means in a portion contained substantially between the shuttle and the first anchoring zone, the shuttle is rotated about its main axis in the opposite direction to the said entangling. The group of N reinforcements is then separated from the shuttle. Each reinforcement of the group is tensioned between the anchoring zones. The preceding steps are repeated until the installation of the reinforcements is completed.

Method for the assembly of a stay

Device for damping the vibrations of a sheet of stays of a work of construction, the sheet of stays comprising at least one first stay () and one second stay (). The device comprises at least one damper () with substantially linear stroke, which has a first connection () articulated on the first stay () and a second connection () articulated on the second stay (), and the axis of the damper () is substantially perpendicular to first and second stays ().

Suspension bridge

Configuration of suspension bridge cables

This relates to a bridge stay formed by a cable (1) which itself is surrounded by a discontinuous sheath composed of identical successive tubular sections (4) having ends which fit together (at 9). This stay comprises an inextensible cablet (10) pulled taut along the cable, on the inside of the successive sheath sections, which cablet is fastened by equidistant fasteners (11), the number of fasteners being equal to that of the sheath sections, each fastener being fixed to a sheath section at a point on this section and the distance (D) between any two successive fasteners fastened to the cablet being equal to the distance between two identical points on two successive sheath sections, which distance is slightly less than the minimum distance envisageable for each section.
