Our Products

STIC is developing and commercialising a number of timber building technologies aimed at meeting the needs of Owners / Developers of commercial and industrial buildings and the Architects, Engineers, Quantity Surveyors, engineered timber fabricators and constructors involved in the design, specification and construction of these buildings. 

The technologies include:

    • Pre-stressed Laminated Veneer Lumber (LVL) or Glue Laminated Timber (Glulam) building frames
    • Pre-stressed cantilevered LVL or Glulam shear walls for buildings
    • Low noise / vibration damped LVL or Glulam floor systems
    • Rapidly assembled LVL or Glulam portal frames and roofs for long span industrial buildings

Importantly, these systems are all pre-fabricated to small dimensional tolerances from homogeneous timber raw materials such as LVL and are quick and easy to assemble during site construction.

Pre-stressing is done during construction and uses conventional multi-strand steel tendons, steel bars or carbon fibre strands.

The overall benefits offered through use of the STIC building and
construction system are summarised as follows:

 Benefit

Constructability

Prefabricated structural timber components

 
  • Minimises on-site work
  • Reduces total construction time
  • High dimensional accuracy achieved with structural components
  • No shims and packers required for accurate member fit up 
    Major structural elements connected via pre-stressed steel tendons
  • Enables rapid erection of multi-storey building frames and shear walls
  • Removes the need to install large numbers of traditional wood fixings such as nails and screws at the intersection of major structural elements
  • Provides a very efficient moment restraining joint
  • Reduces total construction time
  • Reduced total building erection cost 

Comparatively lightweight LVL and Glulam timber members

  • Smaller on-site crane capacities required to erect building
  • Lower crane costs 

Comparatively lightweight timber floor units

  • Increased crane time utilisation.  Crane not required for fine positional placement of floor units once lifted into approximate position

Environmental sustainability

Sequestered carbon

 
 
  • Timber structure has stored CO2 which off-sets the CO2 emissions associated with other building materials such as aluminium, glass, steel, concrete etc
  • Can achieve a carbon neutral building (embodied energy) 

Health and safety

Comparatively lightweight LVL and Glulam timber members and floors

 
 
  • Lighter members resulting in lower risk of serious injury to construction workers during construction
 

Building limit state load performance

Structural integrity

 
  • Building structure able to sustain a major earthquake (Richter scale 7.0 – 7.9) without structural damage and able to return to original position without permanent offset or tilt 

Availability of materials

LVL

 
 
  • LVL is readily available in New Zealand and Australia.  Key manufacturers and suppliers are Nelson Pine Industries Ltd, Carter Holt Harvey Ltd and Wesbeam Pty Ltd

Prefabricated structural members

 
  • McIntosh Timber Laminates Ltd,  Hunters Ltd and Timberbuilt Pty Ltd are experienced at fabricating large structural elements from LVL to small dimensional tolerances 

Building weight

Timber density of 500kg/m3 compared to concrete 2450kg/m3

 
 
  • Lighter building structure (timber 1/5th density of concrete) enabling smaller foundations resulting in lower cost footings
  • Smaller foundations resulting in less time required for foundation earthworks
