Increase Productivity and Programme Certainty With Off-site Manufactured Timber Systems
Johann Betz, Founder and Director, Offsite Design Ltd & Julian Damm, Lead Manufacturing Detailer and Digital Builder Friday 6 June, 2:50pm |
|
This session will introduce a range of value-add off-site manufactured (OSM) timber systems including built examples and provide a comprehensive overview on how to approach the entire process, from pre-construction to installation.
Some OSM timber systems, including supply options, covered in this talk:
The talk will also introduce entry level off-site manufacturing processes for closed light timber framed panels (walls, floors, roofs) aligned with NZS3604:2011.
Johann Betz is Founder and Director of Offsite Design Ltd (www.offsitedesign.co.nz), a consultancy supporting the design, manufacture, and construction of off-site manufactured timber buildings. Johann has a degrees in prefabrication and timber engineering aimed at the German prefab housing industry. He also holds a Masters of Engineering in Wood Technology focusing on the industrial engineering of off-site manufacturing factories.
In New Zealand Johann has worked with numerous prefabricators and contractors, from start-ups to some of the largest prefabricators and mass timber contractors. Current and former clients include Redstag Timberlab, Naylor Love, Hawkins, CleverCore, Concision (now called Innofab), Lt McGuiness, Nelson Pine Industries, Ecopanel and many more.
Johann is member of NZIOB, a founding member of PrefabNZ (now called OffsiteNZ) and currently serving a second term as member of the board.
Julian Damm is lead Manufacturing Detailer and Digital Builder at Offsite Design with 5 years experience modelling off-site manufactured timber buildings for CNC manufacture and on-site assembly. He also has 16 years on-site building experience as a carpenter, foreman and site manager, building residential homes from entry level to large high end residential homes.
Julian has a genuine passion in taking the headache out of traditional site-based construction by solving design and construction issues before they hit the site.
Some OSM timber systems, including supply options, covered in this talk:
- Partially/fully closed light timber framed wall panels, roof and floor cassettes;
- cross-laminated timber (CLT), parallel-laminated timber (PLT), nail-laminated timber (NLT),
- timber and structural steel hybrid buildings
- CNC cut structural components
The talk will also introduce entry level off-site manufacturing processes for closed light timber framed panels (walls, floors, roofs) aligned with NZS3604:2011.

Rigid insulation is increasingly being specified and used in both residential and commercial construction across New Zealand. Kingspan Thermakraft aims to present to New Zealand Certified Builders to ensure a uniform understanding of the following key points:
- Builders can save money and meet H1 compliance by using 90mm timber framing with rigid insulation boards.
- Continuous insulation eliminates the dew point on the internal side of concrete walls, simplifying construction methodology and installation.
- Continuous insulation helps save space in buildings throughout New Zealand.
The presentation will include:
- Practical installation instructions and imagery.
- Thermal performance modeling and dew point analysis for various wall constructions to provide a comparison between rigid insulation and traditional stud and frame with fibrous insulation.
- Examples of modeling floor space with various insulation constructions to demonstrate how rigid insulation can recover floor space in the design.

CodeMark vs. Product Appraisals: What Builders Need to Know
Daniel Wellington, BDM Engineering Building Solutions, Residential APAC, MiTek
Saturday 7 June, 11:00am
Selecting the right building products is about more than just performance—it’s about ensuring compliance, avoiding delays and managing risk. With increasing scrutiny around building product approvals, understanding the difference between CodeMark certification and product appraisals is essential for builders, architects and specifiers who want to make informed decisions and keep projects on track.
This seminar will unpack the key differences between CodeMark certification and product appraisals—giving builders, architects and specifiers the knowledge to make informed choices that streamline compliance and reduce project risks. Attendees will gain insight into how CodeMark certification ensures automatic acceptance by Building Consent Authorities (BCAs), whilst product appraisals, although valuable, do not guarantee acceptance and may require additional supporting documentation.
CodeMark certification goes beyond a one-time assessment. It involves rigorous physical testing for structural properties, strict compliance with manufacturing QA and QC requirements and ongoing audits to ensure continued compliance. This additional oversight increases public confidence, reduces risk for builders and ensures the materials used in construction meet the highest standards of reliability.
Key takeaways:
Daniel Wellington is a Mechanical Engineer with Honours from the University of Auckland and a specialist in structural timber engineering. With nearly a decade at MiTek, he works closely with engineers, architects, builders and frame & truss manufacturers to deliver efficient, engineered solutions for low to mid-rise timber buildings.
He has a strong focus on optimising construction outcomes, including the adoption of MiTek systems and multi-story light timber frame structures. Daniel played a key role in adapting the Z4 continuous rod system for New Zealand and is committed to educating the industry on better building practices. His work supports MiTek’s global commitment to smarter, more efficient construction.
