Welcome to QSX – Global Excellence in Construction Dispute Resolution

Established in 2022 by Mark Grant, QSX is a construction industry quantum and delay powerhouse that seamlessly integrates domestic success with a dynamic international presence.

Mark’s 40+ year African career in project management and quantity surveying, together with his international experience with industry bodies like the International Construction Information Society and the International Cost Engineering Council anchors our legacy. His further international qualifications and experience in commerce, management, information technology and law places us at the forefront of innovation as experts in the field of construction quantum determination and forensic delay analysis.

Operating at the intersection of operational, financial, commercial and legal acumen, QSX staff hold advanced degrees in construction science, information technology, commerce, management and law as well as professional registrations with the South African Council for the Quantity Surveying Profession (SACQSP) and the South African Council for the Construction and Project Management Professions (SACPCMP).

These professional registrations ensure adherence to the South African construction industry’s highest statutory standards, and as proud members of the Association of South African Quantity Surveyors and the Association of Arbitrators (Southern Africa), we bring a wealth of experience to every assignment.

Because of our particular combination of skill sets we are in the unique position of being able to offer simultaneous construction delay analysis and quantum determination services – resulting in considerable time and cost savings in construction dispute resolution.
