On March 22nd 2017, a terrorist attack unfolded on Westminster Bridge which would result in four fatalities, and around 50 serious injuries as a vehicle was used as a primary weapon against the public. 

During the attack, the vehicle deliberately mounted the pavement but ultimately drove around TSP Projects barriers installed in Bridge Street opposite Westminster Station. These barriers had originally been installed to protect the base of the iconic clock tower from vehicle borne IED (improvised explosive device) attacks and the presence of the barriers resulted in the driver deliberately avoiding them.

During evidence given at the recent Coroner’s inquest into the tragic events, this was acknowledged in that it was stated that whilst the barrier installation was not intended to provide protection to pedestrians as their primary role, on the day “the vehicle was essentially forced to go back onto the road and go around the barriers” and “quite a number of pedestrians (were) protected by those barriers”. 

These barriers along with the multiple layers of security measures along the boundary and within the Palace of Westminster were installed between 2005 and 2007 by the then Corus Bi-Steel, a forerunner to the current TSP Projects Security Sector.

The range of Hostile Vehicle Mitigation (HVM) products offered by TSP Projects Ltd have been developed over more than a decade , as part of a CPNI run programme to encourage industry to provide  independently tested product  with defined performance ratings.

The TSP Projects range of redeployable HVM products have been subjected to both vehicle impact testing under PAS68 and blast categorisation tests conducted by independent bodies.
