Abstract: Fiber optic sensors are used to monitor the integrity of a subsurface concrete structure such as a pile or diaphragm wall. A fiber optic sensor array (48) is attached to a reinforcement or framework assembly (20) for the subsurface concrete structure. Concrete is applied to surround the reinforcement or framework assembly (20) and fiber optic sensor array (48). The fiber optic sensor array (48) is then used to collect temperature data during hydration of the subsurface concrete structure. The temperature data is monitored in real time to determine differentials across the structure, indicative of a problem within the structure.

Abstract: A modular bridge is formed from a plurality of bridge modules (4), the bridge (2) having a longitudinal direction along the spanning direction and including: a first longitudinal compression member (11,13, 70) that is, in use, at an upper part of the bridge cross-section; a second longitudinal compression member (9, 72) that is, in use, at a lower part of the bridge cross-section; a structural lateral element (9) for forming a deck of the bridge or for supporting deck elements of the bridge; a shear element (14, 16) for carrying a shear load; and a tension member (6) applying a compressive force to one of the longitudinal compression members (1,13, 70); (9, 72) such that when in use the other of the longitudinal compression members (1,13, 70); (9, 72) forms a main compression element for the bridge (2) and the tension member (6) forms a main tension element for the bridge (2).

Abstract: A seating arrangement for stadia and the like includes a beam for receiving one or more seats, where the seat has a backrest portion fixedly mounted to the beam and a movable seat portion mounted on the beam for pivotable movement about the beam from a generally horizontal seating position to a generally upright non-seating position.
