Seismic assessments (ISA/DSA) and structural strengthening design for Northland commercial buildings. Core Engineering delivers %NBS ratings and full strengthening solutions from one team.
Enquire TodayMany councils and banks now require a Seismic Assessment before approving change of use, building consent or mortgage applications on existing commercial structures. A seismic assessment determines the seismic capacity of a building compared to the current New Building Standard (NBS), expressed as a percentage (%NBS).
Buildings assessed at below 34% NBS are considered earthquake-prone under the Building Act 2004 and may require strengthening or have restrictions placed on their use. Core Engineering's structural team completes these assessments efficiently and cost-effectively, giving building owners and their advisors the information they need to make decisions.
We carry out Initial Seismic Assessments (ISA) through to Detailed Seismic Assessments (DSA), and where strengthening is required we can provide the full structural strengthening design — all from the same team that completed the assessment.
Rapid desktop and visual assessment to determine whether a DSA is required. Cost-effective first step for building owners.
Full structural analysis determining %NBS rating. Required for council earthquake-prone building registers and finance.
Where strengthening is required, our team designs and documents the works — from concept to construction-ready drawings.
PS1 (design) and PS4 (construction review) documentation for strengthening works to satisfy council requirements.
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.
