HOW WE HELP
We work closely with architects, project managers and consultants to support integrated, efficient and buildable project solutions.
Our multidisciplinary team works alongside design professionals, drawing on long‑standing experience across a wide range of consultant‑led projects, and providing clear and practical engineering input from initiation, master planning and concept design through to construction.
We prioritise early coordination and responsive communication, with design input that supports spatial intent and project requirements as work develops. It’s a collaborative approach that helps keep projects moving smoothly, with fewer surprises and better outcomes.
01
EARLY INPUT
We provide upfront technical insight that informs concept design, clarifies planning constraints and identifies engineering considerations early, helping architects and project managers make informed decisions from the start.
02
INTEGRATED DESIGN
Our civil, geotechnical and environmental teams collaborate closely with the design team, contributing engineering solutions that align with the design vision, site realities and project programme requirements.
03
APPROVALS & DOCUMENTATION
We prepare clear technical documentation and support consultants through planning, consent and authority approvals, while working alongside other disciplines to help keep information aligned.
04
DELIVERY SUPPORT
During construction, we provide tendering and construction management and observations, responsive engineering input, site reviews and problem-solving to keep your project moving efficiently and help contractors deliver the design as intended. Our established and growing footprint across the South Island means we can do this efficiently with people who understand local conditions.

OUR SERVICES

Geotechnical input is one part of a wider picture, helping to support decisions as a project moves from concept through design, consenting and construction.
If you’re building or subdividing, we will work with you to understand the ground conditions and any geotechnical constraints relevant to your project.
We’re involved at different points depending on the site and what’s being planned. Sometimes that’s early, when options are still being explored. Other times, it’s to support design, consenting or construction once decisions are underway.
Across these stages, geotechnical input helps clients to understand ground conditions, identify relevant considerations and discuss what those mean for the project as it develops.

Our environmental scientists investigate land, water and air.
We work with all stakeholders and service providers to help create environmentally sustainable outcomes. Our comprehensive services can be provided as part of a multi-disciplinary project, or as a standalone service for any project specifically requiring environmental science expertise and solutions.
We carry out contaminated land investigations, environmental monitoring and technical environmental assessment, documented through reports that reference relevant standards and guidelines.

With over 90 years of experience, we provide a full range of survey services to support projects across the South Island.
We support homeowners, developers, designers, farmers, architects, solicitors, contractors and more.
With a range of survey services, we provide clarity, certainty and confidence for informed decisions on land and development. Whether you’re making decisions about property, managing public or private infrastructure, or delivering a design or construction project, accurate survey information matters.

When a project needs resource consent, we help explain what’s required and guide you through the process.
Our planning team helps make sense of New Zealand’s planning framework by providing clear advice and preparing resource consent applications. We also prepare assessments of environmental effects (AEEs), coordinate technical inputs and work directly with councils.
From residential and commercial developments through to industrial, rural and subdivision projects, we provide early planning advice and detailed documentation. This helps identify planning and project considerations that need to be worked through as part of the consenting process.

FAQ
Got questions? We’ve got answers.
Yes. Much of our work involves supporting architect led and consultant led projects. We work alongside design teams as projects develop, providing engineering, planning and surveying input that supports design intent and the way a building or site is meant to work.
Yes. We regularly work as part of wider consultant teams led by project managers. We’re familiar with the coordination, programme and communication requirements that come with these projects and stay closely connected as designs, documentation and construction phases progress.
Yes. We’re often involved early to provide technical input during concept design and feasibility, and we can continue supporting projects as they move through detailed design, approvals and construction. Our involvement is shaped by the project and the needs of the consultant team at each stage.
Yes. Our civil, geotechnical, environmental, structural, planning and surveying teams work closely together. This allows technical input to be coordinated internally before it’s shared with the wider consultant team, helping keep information aligned as projects move across disciplines.
Yes. We support consultant‑led projects across the South Island, with teams based in Christchurch, Nelson, Greymouth, Timaru and Wānaka.
