Holtekamp Bridge is done by the first method in Indonesia, that is strand lifting method (full span). This method takes into consideration the seismic risk factors at the project sites that are high, so it would be very risky if the implementation process is done completely on site.
The main concept of this method is to work on the installation process as quickly as possible to reduce the risk of the earthquake. In view of these risk factors, the main spreading steel welding work is segmentally conducted in Pasuruan by PT Bromo Steel Indonesia, a subsidiary of PT Boma Bisma Indra (Persero).
