Museum of Human Evolution
Work on the site began in 2004 and The Museum of Human Evolution was inaugurated on July 13, 2010. Its foundation is based on the archeological site of Atapuerca, located 20 km (12 miles) east of Burgos. The Atapuerca site has been designated a UNESCO World Heritage Site.
The specialist geotechnical company KellerTerra were contracted to construct the deep foundations which would be used to support the structure and for underground parking and the lower levels of the museum.
Part of this deep foundation required the construction of a diaphragm wall to a depth of approximately 20 metres.

Monitoring
Data on diaphragm wall deflection was regularly monitored to ensure construction quality and the safety of adjacent buildings, particularly important given its high density urban setting. Due to the depth of the excavation and the proximity of ancient buildings, extensive monitoring was necessary within the diaphragm walls by means of embedded vibrating wire strain gauges and inclinometer casing. From this the load on the diaphragm wall and deflection could be measured. Tie back anchors were monitored using vibrating wire anchor load cells.
All strain gauges were connected to a data logger and Monitoring Point, a web based data visualisation software where the data could be viewed through the internet. Pre-set trigger levels were set and a regime of alarms developed as part of the construction safety system.
Inclinometers were also installed around the excavation to measure any movement of ground.
