Residential and commercial architectural drafting, building consent and BIM management services

Supporting commercial projects with technical expertise from consent to construction

Commercial projects become increasingly complex once they move beyond concept design. Detailed technical documentation, building consent requirements and coordination between architects, engineers and specialist consultants all need to come together before construction can begin with confidence.
Irvine Technical Consulting specialises in the technical side of commercial architecture, supporting hotels, apartment buildings, offices and other complex developments with detailed documentation, building consent and BIM expertise. Whether engaged directly or working alongside an architectural practice, we help deliver technically sound, durable buildings that perform long after the project is complete.

Technical documentation and building consent for complex commercial projects


Many architectural practices produce outstanding concept designs but need additional technical expertise as projects progress towards building consent. Irvine Technical Consulting regularly works alongside architects, developers and project teams, providing the technical documentation needed to move projects confidently into construction.
Our commercial work includes:

  • Technical documentation for hotels, apartment buildings, offices and commercial developments.
  • Building consent documentation, council coordination and responses to Requests for Information (RFIs).
  • Fire safety and durability detailing integrated into the documentation process.
  • Technical coordination with architects, engineers and specialist consultants.
  • New builds, alterations, reclads and commercial refurbishment projects.

Resolving historic Code Compliance Certificate and building consent issues

Missing Code Compliance Certificates can delay property sales, refinancing or redevelopment for years after construction has finished. Irvine Technical Consulting helps owners resolve historic building consent issues by identifying what prevented code compliance and coordinating the documentation required to work through the council process.
Our experience includes commercial buildings, where incomplete documentation and outstanding compliance issues prevented a Code Compliance Certificate from being issued. We work with property owners, asset managers and consultants to achieve practical, compliant outcomes.

BIM coordination that reduces costly construction clashes

On larger commercial developments, successful projects rely on every consultant working together. Our BIM management service coordinates architectural, structural and building services models, helping identify potential conflicts before they become expensive problems on site.
We are regularly engaged by architectural practices that need additional BIM capability, providing specialist support on hotels, apartment buildings and other complex commercial developments. Detailed 3D modelling also gives clients and stakeholders a clearer understanding of the finished project, helping identify critical junctions, improve decision making and reduce changes during construction.

Frequently asked questions for Commercial Architecture

Projects are typically picked up once a concept moves into detailed documentation and building consent. Engagement can happen directly with the client, or alongside an architect who needs specialist technical documentation support for a hotel, apartment block or office.

Yes. Irvine Technical Consulting is based in Auckland and works with commercial clients across the North Island and wider New Zealand, including Queenstown. Meetings are usually held online or on site, depending on the project.

Yes. Historic building consent work can be arranged to resolve the issues that prevented code compliance originally, then coordinate the process through council. This has included buildings dating back to 1994 with unresolved CCC files.

BIM management focuses on coordinating models from all consultants, catching clashes between structure, services and architecture before construction. It sits alongside design work rather than replacing it, and can be provided as a standalone consultant service.

Commercial coordination typically uses Procore and AconX alongside project managers and main contractors. Specific platforms depend on the scope, budget and how the client wants information shared across consultants during documentation and construction.
