 DESIGN IT
designIT is a software tool for all building practitioners for the design of Carter Holt Harvey’s Engineered Woodproducts range and other selected materials for houses and similar structures. Quick and simple to use yet deceptively powerful software, designIT is useful for the selection of beam sizes without the need for engineering knowledge or the exercise of professional engineering judgment.
Features
- Software Compliance
designIT software complies with the requirements of the ’’ABCB Protocol for Structural Software Version 2011.1’’ The compliance document is located here.
- Based upon AS 1684.1
Design criteria and updated to include for the AS/NZS 1170 - 2002 design requirements, now including AS/NZS 1170.3 Snow and ice actions, and for New Zealand, includes recommendations from DBH Practice Advisory 9
- Includes options for design
With commonly available stress grades of timber and glue laminated timber (Glulam in Australia only).
- Caters for a range of floor live loads
Needed for design of decks, balconies and residential apartment buildings (up to 3.0 kPa / 2.7 kN).
- Includes a floor joist calculator
To allow consideration of actual load and support conditions for optimum design, web hole placement and specification of hangers.
- Bearer calculator (similar to joist calculator)
Allowing for consideration of a wide range of load and support conditions including offset and parallel load bearing walls and support of concentrated loads to provide optimum solutions without the need for engineering design.
- Serviceability report
Showing the estimated average deflection and the corresponding limit for the critical load case together with the permanent load deflection (where applicable).
- Reaction report
For each member, providing designers with the flexibility to detail connections using Timber Framing Standards and proprietary connections.
- Reference to specific details
Relating to hyJOIST used in roofs and floors..
Prior releases

V5.0.2, V5.0.1
Minor updates
DESIGNit series 5 BASE RELEASE
designIT Series 5 is the latest release of CHH Woodproducts designIT for houses software platform. This major release not only includes required changes to design properties of LVL, timber grades and design standards, but additional functionality including enhancements to the floor joist calculator, new lintel design screens and the ability to design wall plates for houses.
- Reaction report for each member, providing designers with the flexibility to detail connections using Timber Framing Standards and proprietary connections.
- Ability to design wall plates for both upper and lower storey load bearing walls
- New lintel design screens, including Lintels supporting two (2) identical TGT’s, Lintels supporting two (2) different TGT’s and Lintels supporting a girder truss and a TGT.
- ‘Special load cases’ functionality for the floor joist calculator. This allows designers to specify floor joists supporting concentrated loads from roofs, walls and floors in similar combinations to those already available in the bearer calculator. Design for hyJOIST as trimming joists has also been added as well as guidance on consideration of differential deflection between closely space members.
- Design for snow load on roofed over structures in both the floor joist and bearer calculators.
- New roof area calculation options for studs, posts, and floor and bearer calculators.
Australian Specific
designIT Series 5 also includes the following additions:
- Adjustments to capacity calculation for compliance with BCA 2011, including re-characterised LVL, timber and glulam grades to AS 1720.1-2010 and AS/NZS 4063:2010.
- Inclusion of pre-cambered glulam GL17 C & GL18 C members for design in Queensland
New Zealand Specific
designIT Series 5 also includes the following additions:
- Adjustements to capacity calculation for re-characterised LVL in accordance with AS/NZS 4063:2010.
- Inclusion of Extra High wind region
- Specification of SG Grades
