What Cullen Grummitt & Roe does

Cullen Grummitt & Roe (CGR) is a privately held, family-owned engineering consultancy founded in 1924 by Mr. E.B. Cullen in Brisbane, Australia, originally to serve expanding shipping and stevedoring companies that owned their own wharves. The firm specializes in port and harbour engineering and has grown into an international practice operating from strategic offices in the United Kingdom, Australia, India, Argentina, Jordan, Canada, Ecuador, Senegal, and Morocco, with project work delivered on every continent except Antarctica.

CGR's core offering is Port & Harbour Engineering — covering feasibility studies, port master planning, concept and detailed design, design verification, tender assistance, project management, site supervision, contract management, due diligence, expert witness services, and independent engineering reviews — supported by Geotechnical Engineering (ground improvement, foundation design, embedded retaining walls, earthworks), Electrical Engineering, and Building Services Engineering. Technical delivery relies on conventional civil/structural engineering methods augmented by advanced Finite Element Analysis (FEA) tools for geotechnical design. The engineering team is multidisciplinary and multilingual (over 15 languages), enabling work across the regulatory and cultural environments of the firm's markets.

The business model is professional services billable, with project-based pricing on bespoke scopes and no publicly disclosed rate cards or tiers. CGR acquires work through direct enterprise engagement with port authorities, terminal operators, shipping companies, and government ministries, supported by industry reputation built over 100 years and referrals — including repeat mandates from DP World, Associated British Ports, China Harbour Engineering Corporation, Dover Harbour Board, Terminales Rio de la Plata, and Portuaria Lirquen. Marketing is minimal: a corporate website, LinkedIn, and X (Twitter) presence, with no active digital demand-generation. Distribution is exclusively direct sales through project tenders, sub-consultancy arrangements with other engineering firms (e.g., Drewry Shipping Consultants), and reputation-driven repeat business.
