Envelope Engineering

What Envelope Engineering does

Envelope Engineering is a New Zealand-founded, privately-held civil and structural engineering consultancy established in 2015 by Alan Blyde. The firm delivers integrated engineering services spanning civil engineering design (earthworks, roading, wastewater, stormwater, infrastructure), structural engineering (including seismic assessment and strengthening), cadastral and construction surveying (incorporating laser scanning and 3D data capture), traffic engineering, flood modelling and water-sensitive design, and end-to-end subdivision and land development project management. Its technical differentiators include heritage site redevelopment expertise (Erskine College), water-sensitive stormwater design achieving total hydraulic neutrality (Wallaceville Estate), car-stacker parking solutions for constrained urban sites (Ramada Hotel), and laser scanning-based surveying accuracy.

The company serves enterprise customers across property development, local government/councils, and sports infrastructure — including Gillies Group, Safari Group, CPMC Limited, The Wellington Company, KiwiRail, NZCIS, and Oyster Property Group. The business model is project-based professional services with negotiated fees per engagement; no public pricing exists. Customer acquisition relies on direct enterprise engagement by Directors and Business Development staff, supplemented by referral networks, project portfolio showcasing on the website, and industry award visibility (Gold Award at the 2025 Registered Master Builders Commercial Project Awards).

Operationally, Envelope has grown from a single Wellington-based founding team to 60+ staff distributed across seven offices: Auckland, Mount Maunganui, Havelock North, Wellington, Christchurch, and an international satellite in Glasgow (Scotland). Expansion has been funded organically with no external investment, private equity, or parent company identified. The ownership structure remains founder/management-led with a flat organizational emphasis on culture, as evidenced by 2025 HRNZ Awards recognition as a Wellbeing Programme finalist.
