HSC

What HSC does

HSC is a privately held New Zealand engineering consulting firm specializing in hydraulic (plumbing, gas fitting, stormwater, trade waste, and water/gas reticulation) design for the construction sector. Founded around 1992-1994 by Peter Downey to address a gap in specialized plumbing and gas fitting design expertise in the NZ market, the firm has expanded into an integrated building services offering covering mechanical (HVAC, heating, ventilation), electrical (emergency lighting, building electrical, CCTV wiring), BIM/Revit and AutoCAD design documentation, construction monitoring, peer review, and NABERSNZ/Green Star-aligned sustainability consulting. Service delivery is anchored by senior engineers who hold Auckland Council Registered Producer Statement Author, CPEng, CMEngNZ, and NZ Certifying Plumber/Gas Fitter credentials, enabling the firm to certify designs across regulatory regimes.

The firm operates from a Newmarket, Auckland headquarters, a Rolleston (Canterbury) office, and a Gurugram, India operations office that supports BIM and drafting workflows, providing a hybrid onshore-engineer / offshore-drafter production model unusual for a sub-50-person NZ consultancy. HSC reaches customers through consultative, relationship-driven direct engagement, with prospective clients booking a no-obligation discovery meeting via the website or by phone. Revenue is generated on a project-by-project, quote-based professional services basis across the full design-to-construction-monitoring lifecycle for construction companies and developers undertaking residential, commercial, hospitality, civic, and retail projects in New Zealand and the South Pacific.

HSC's stated value proposition centers on "never overengineered" buildable designs that reduce installation cost, supported by 30+ years of hydraulic experience and a self-reported involvement in approximately 75% of Auckland's high-rise apartment buildings completed over the past two decades. The firm is currently led by Managing Director Gurpreet Singh Sokhi and Director Kumar Shreshth Bhola following a leadership transition from founder Peter Downey. HSC is privately owned, discloses no revenue, has no institutional investors, parent company, or subsidiaries, and competes against other NZ building services consultancies in a market where regulatory credentials and local relationships are the primary switching costs.
