Our Business

53Quantum was founded in 2004 to provide efficient and detailed cost analysis services to clients in the engineering and construction industries, involved in claim disputes.

With a proven track record in adjudication, arbitration and litigation, in London and across the UK; 53Quantum’s services are now sought by a myriad of clients, from business owners, commercial directors/managers to those in the legal sector,  looking for assistance with a claim.

In recent years, 53Quantum has sought to build on its more traditional offering by utilising new, cutting-edge technology, which not only allows the capture and analysis of relevant data in the defence of a claim but more importantly empowers a client to future-proof its business.

With the right analytical tools, employed from the outset, the team at 53Quantum strongly believe that many of the reoccurring issues arising on projects can be avoided. This increasing focus on the delivery of state-of-the-art Business Intelligence and visualisation software to our clients is what we call QUA2.
