About us
QSX commenced operations in Durban, South Africa in March 2022 as a highly specialised boutique firm providing alternative dispute resolution services to the construction industry — servicing both local and international clients.
We leverage highly skilled staff together with local and international connections, and we work both independently and in conjunction with other specialists, including some of South Africa's largest law firms and consultancies.
Capabilities
Our competencies and experience span the full spectrum of alternative dispute resolution available to parties in construction and infrastructure contracts.
Independent expert evidence on quantum and delay — reports prepared to withstand scrutiny, and testimony given with clarity and impartiality. Substantial experience gained alongside leading construction and energy infrastructure lawyers.
We understand that adjudication as a dispute resolution mechanism is there to keep the life blood of the industry flowing — cash flow. Speedy, but robust and well-considered decisions from experienced practitioners is what is required. We have the experience and training to quickly get to grips with complicated construction issues and deliver the core competencies for successful adjudications.
Informed by postgraduate training in international dispute resolution and being well informed of leading institutional rules, we are keenly aware of the unique complexities of international arbitration, which is underpinned by substantial local experience — acting as experts and also as arbitrators.
Facilitated, commercially-minded and trusted fair engagement aimed at avoiding disputes before they consume the programme and the budget — but with the same rigour of analysis behind the scenes, built on a solid multi-decade knowledge repository that only experience can bring.
AI readiness
QSX is working at the cutting edge of frontier and bespoke AI solutions, including developing on-premise AI model hosting and training where confidentiality is paramount.
For example, recently we employed frontier AI, applied to a large retail development's drawing sets (architectural and structural). Both sets indexed, characterised and reconciled; gross building area measured directly from CAD geometry to ASAQS rules. Weeks of manual take-off compressed into days — every figure traceable to the drawing it came from for manual 'human-in-the-loop' cross-checking.
