Geotechnical and structural construction inspections and PS4 Producer Statements across Northland. Core Engineering covers residential, commercial and infrastructure projects from one integrated team.
Enquire TodayQuality assurance during construction is an essential part of any engineering project. From geotechnical verification at foundation excavation through to structural inspections at key construction stages — Core Engineering provides professional construction inspection services and the associated Producer Statement documentation required by councils throughout Northland.
We hold extensive experience in construction inspections for both geotechnical and structural works, principally across Northland and the Far North. We have a strong reputation for our professional and collaborative approach, working alongside contractors and builders to resolve issues efficiently without compromising quality.
As a multi-discipline firm, Core Engineering can carry out both geotechnical and structural construction inspections under a single engagement — reducing cost, simplifying scheduling and giving the building owner a single PS4 package at completion rather than having to coordinate sign-off from separate consultants.
Foundation excavation verification, subgrade assessment and fill compaction verification against geotechnical report recommendations.
Key-stage structural inspections of reinforcement, connections, framing and other structural elements per the consented design.
Construction Review (PS4) documentation for geotechnical and structural works — required for Code Compliance Certificate.
Stage inspections for retaining wall construction — footings, drainage layer, tie-back installation and facing elements.
On-site wastewater system installation verification and completion documentation to TP58 and AS/NZS1547 requirements.
Civil works inspections for subdivision infrastructure — earthworks, drainage, roading and services.
Founded in Whangarei in 2020 by David Leslie, Core Engineering Solutions Limited was built around a simple idea: bring genuinely qualified, multi-discipline engineers under one roof and deliver real value to every client — not just a report, but a solution.
Our engineers hold Chartered Professional Engineer (CPEng) status — the highest professional credential in New Zealand engineering. You get qualified expertise, not junior sign-offs.
Our engineering team brings over 30 years of combined experience across civil, structural and geotechnical disciplines — spanning residential, commercial, infrastructure and rural projects throughout Northland.
Civil, structural and geotechnical under one roof. No coordinating between firms, no conflicting reports — your project is handled start to finish by a team that works together.
We focus on practical solutions that work for your project and your budget — not over-engineered complexity. Clear communication, straightforward advice, and documentation that gets your consent through.
Based in Whangarei with a Waipu office, we are a genuinely local firm — we know Northland ground conditions, councils and communities from the ground up.
