KEDMOR pioneered bridge maintenance surveys in the country. Aging stocks of bridges require maintenance in order to prevent breakdown or interrupted service. Such operations require clear prioritization, in order to make the best use of resources. KEDMOR provides bridge inspection, analysis and maintenance surveys. Surveys and inspections are carried out according to internationally proven methodologies, adapted where needed to specific local characteristics. Inspections are performed for specific needs as well, such as post impact damage assessment.

Bridge inspections are performed by well-trained and equipped teams. Recommendations are made to optimize the design of the repairs and maintenance.

Em HaMoshavot

Location: National Highway No. 4, Israel.
Date: 2011 onwards
Services: Structural Monitoring

General DescriptionEm Ha’Moshavot Bridge is located perpendicular to the future Red line of the Light Rail Transit (LRT) and axis 2 of the bridge is located between the LRT future tunnels.

The bridge is based on piles. The boring and excavation of the LRT tunnels will be on each side of the piles at axis 2. In order to avoid mutual impact between the bridge and the tunnels, the piles are monitored 24 hours a day for deflections and strains.

Monitoring Method
The piles are equipped with 3D strain gauges, slope gauges and fiber optics to monitor strains. All gauges are connected to a Data logger set in the girder. The data logger sends all information to Kedmor computer.

Quarry Bridges

Location: Near Nazareth , Israel
Date: Completed in 2008.
Services: Structural Monitoring.

General Description
Quarry Bridges are located on road no. 60, near the Iksal junction, above the former "Roichmen Quarry". The superstructure of the two bridges is made of a box girder 3.30m deep. The total width of each bridge is a constant 11m.

The north bridge
The bridge has a total length of approximate 414m, which is divided into 6 spans; 1x 46.6, 2x78, 2x 77 and 1x56m.

The south bridge
The bridge has a total length of approximate 409m, which is divided into 6 spans; 1x 45.4, 2x76, 2x 77 and 1x56.1m.


Pier 2 is much shorter, and therefore stiffer than the other piers of this bridge. A special gap-element at the top of this pier enables the rest of the columns to respond prior to this pier in the event of an earthquake and by that prevent premature failure.

A non-linear gap element was implemented as part of a pushover analysis in order to fine-tune the over-all earthquake response of the bridge.

Construction Method
The bridges designed in two construction methods. The west part of the bridges – cast-in-place Incremental launching.
The east part of the bridges – Precast Balanced Cantilever Method of construction. The maximum length of a segment in the incremental launching method is 22.5 m. The length of a typical segment in the balanced cantilever method is 3 m.
