The QSi

What The QSi does

The QSi (Quantity Surveyors International) is a UK-headquartered not-for-profit professional body founded in 2004, dedicated to Quantity Surveyors and adjacent construction-commercial professionals including Construction Managers, Estimators, and Project Managers. The organization operates a global chapter network spanning the UK (with regional sub-chapters across Scotland, Northern England, Midlands, South West, South East, Wales, Northern Ireland), Ireland, New Zealand, Hong Kong, MENA, Qatar, Sri Lanka, and the USA, supported by 7 staff and a Global Board of senior industry figures. Core offerings include tiered individual membership (Fellow, Member, Associate, Retired, Student) at £50-£125 per year, corporate membership at 50% discount for organizations with 5+ members, CPD seminars and webinars, university course accreditation, a quarterly QS Eye e-magazine, a Surveyor Search directory, a premium document repository, and a Research Directorate.

QSi has no proprietary technology platform; its core function is professional credentialing, CPD delivery, advocacy, and member services. The digital surface consists of an online membership portal (theqsi.com) and a LinkedIn community group. Technology-enabled product capabilities are delivered through partner integrations: Metroun provides an online education platform with AI-assisted features, and Feenix Ltd provides responsible AI training. The organization also partners with the Chartered Institute of Building (CIOB) as a certified provider of the Chartered Membership Programme and is a partner of the International Cost Measurement Standard Coalition.

Revenue is generated through recurring annual membership subscriptions across tiers, supplemented by CPD event fees, premium document access, and corporate membership arrangements. Customer acquisition is community-led, driven by industry events, university partnerships, and the global chapter network. The organization is governed by a volunteer-heavy board structure with regional sub-boards, and recent strategic emphasis has been on responsible AI education, insurance partnerships, and international chapter expansion in MENA and Asia-Pacific.
