JHK and Associates Pty Ltd

What JHK and Associates Pty Ltd does

JHK and Associates Pty Ltd is a privately held Australian engineering consultancy specializing in civil, structural, and maritime engineering design and certification. Established in June 2019 as the successor to C W Henstock and Associates (founded 1988), the firm operates from a single Sydney office in Yagoona, NSW with a 5-person team led by Principal Engineer Pira Myooran (45+ years of experience). The company delivers professional engineering services — investigation, concept design, detailed design, documentation, contract administration, construction supervision, inspection, and certification — across bridges, culverts, internal roads, retaining walls, foundations, boat ramps, pontoons, piles, sea walls, jetties, wharfs, and recreational marinas up to 300 berths, with designs compliant to Australian standards (AS5100, AS3962, AS4678, AS4997, AS2159).

The firm's underlying technical capability rests on finite element modeling, proprietary in-house analysis programs, and an integrated management system certified to AS/NZS ISO 9001:2016 and AS/NZS ISO 45001:2018. Revenue is generated through project-based consulting fees billed under individually negotiated proposals, with no standard pricing or subscription tiers. The go-to-market is sales-led, relying on direct client engagement, tender responses, fee proposals, and reputation-driven referrals rather than digital or channel marketing. Customer segments split horizontally between government (federal, state, local councils, defence, national parks) and private commercial enterprises (marina operators, industrial facilities, hospitality, manufacturers).

The customer base includes Australia Border Force, Defence Estate Organisation, HMAS Creswell, multiple NSW and interstate local councils (Canada Bay, Liverpool, Parramatta, Tenterfield, Bega Valley, Swan Hill), and commercial clients such as Viva Energy Australia, Lubrizol International, Shellharbour Marina, and the Australian National Maritime Museum. Geographic delivery extends beyond NSW into Tasmania, Victoria, and Queensland. The company has no external investors, no subsidiaries, and operates as a tightly-held professional services firm with continuity provided by inherited personnel, projects, and the legacy C W Henstock trading name.

Broad incumbents

• Aurecon: Large Australian-headquartered engineering, design, and advisory firm competing for the same government infrastructure and waterfront tenders at a much larger scale.
• SMEC (Surbana Jurong): Australian-origin engineering consultancy now part of Surbana Jurong, with a strong footprint in bridges, roads, and water infrastructure comparable to JHK's civil portfolio.
• WSP Australia: Global engineering consultancy with a substantial Australian practice competing for the same government civil and maritime infrastructure mandates.
• GHD Group: Major Australian employee-owned engineering, architecture, and environmental consulting firm; broad overlap with JHK in civil, structural, and waterfront infrastructure work.

Direct peers

• Northrop Consulting Engineers: Mid-sized Australian multidisciplinary engineering consultancy with civil, structural, and related disciplines. Closely comparable in scale, multi-discipline offering, and government/private client mix to JHK.
• BG&E Consulting Engineers: Mid-sized Australian engineering consultancy active in civil, structural, and maritime-adjacent infrastructure; comparable size and multi-state footprint.
• Taylor Thomson Whitting (TTW): Sydney-based structural and civil engineering consultancy with similar project size and NSW public-sector client base. Comparable in service mix and in the structural/civil waterfront niche JHK serves.
• Pritchard Francis: Mid-sized Australian civil and structural engineering consultancy with a similar profile of government, mining, and infrastructure clients; relevant scale and service overlap.
• Birzulis Consulting Engineers: Australian structural and civil engineering consultancy operating in the same mid-market segment with comparable public and private project work.

Others

• Maritime Constructions: Australian marine infrastructure specialist delivering construction (rather than design consultancy) for jetties, wharves, and seawalls — comparable end market but different layer of the value chain.
