A08.99.2020 Fire resistance testing tunnels Municipality of Leiden
The Municipality of Leiden intends to test the fire resistance of the Stationspleintunnel on the Schipholweg. Six in-situ tests will be conducted in which a 1 x 1 m oven subjects the tunnel wall and ceiling to heat according to the RWS fire curve. Temperature development is monitored and recorded using sensors embedded in the concrete. The assignment is a service contract without public announcement, negotiated via a procedure without contract notice. The contractor must possess expertise in tunnel fire resistance, oven testing installations, sensor technology, and data processing. The tests must comply with RWS standards, provide accurate temperature registration, and report results in a timely manner. The location, the scale of the tests, and the necessity for accurate monitoring make the assignment technically demanding.

The Municipality of Leiden intends to have fire resistance tests carried out, including in the Stationspleintunnel on the Schipholweg in Leiden. The tests are conducted to gain insight into the spalling behavior of the existing concrete. A total of 6 “in situ” tests will be performed. The tests are carried out by means of an oven over an area of 1 x 1 m², subjecting the wall and ceiling of the tunnel to heat. The ovens simulate the heat released according to the RWS fire curve. During the tests, the temperature development is monitored and recorded by means of sensors in the concrete.
02Exclusion grounds
