What HMS Group does
HMS Group is an Australian construction-industry professional services firm headquartered in Sydney (Level 35, One International Towers, 100 Barangaroo Avenue) with a second office in Melbourne (Level 27, 101 Collins Street). The company was founded in 2015 by Hamish Mehdinezhad, who serves as Founder and Managing Director. It is privately held with no recorded funding rounds, no parent company, and no disclosed headcount.
The firm operates six interconnected service lines: Arbitration, Adjudication, Expert Determination, Expert Witness services, Quantity Surveying, and Estimated Development Cost (EDC) Reports. Core technology consists of industry-standard quantity surveying software and cost estimation tools; no proprietary platforms, APIs, or AI/ML capabilities are described in the source material. Service delivery is anchored to the founder's professional registrations — Registered Adjudicator (QBCC and Northern Territory Government), Registered Quantity Surveyor (Victorian Building Authority panel), Expert Determiner and Witness on the RICS DRS Australasia Expert Panels, plus a Professional Certificate in Arbitration and a Civil Engineering and Science degree.
HMS Group generates revenue on a quote-based, engagement-by-engagement professional services model with no publicly disclosed pricing. Its primary customer segment is the construction industry — property developers, head contractors, and subcontractors — with secondary segments in legal services (law firms and courts requiring expert testimony) and property owners/investors requiring cost management. The firm reports 80%+ of clients acquired via word-of-mouth referrals and 70%+ repeat customer engagement, supported by a 5.0 Google rating across 44 reviews. Marketing channels are dominated by referrals, supplemented by LinkedIn presence, educational content (articles and an e-book), and Google reviews as social proof. Service geography is restricted to New South Wales and Victoria.
