Wilco Precast

Helping Out Our Future Engineers

Wilco is assisting engineering students from University Of Auckland in a testing programme to verify the performance of proprietary threaded inserts as a connection for precast wall panels. This is a result of the Christchurch earthquake when concerns were raised regarding the capacity of inserts and the load transferring mechanism. The testing, conducted at Wilco’s Papakura plant, has consisted of loading the panel foundation connection out-of-plane, both monotonically and cyclically, with various insert arrangements to assess the strength relationship between the panel and the connection.

The bulk of the research has been carried out by Part IV engineering students, Tautua Faitotoa and James Burley, however more recently Sam Corney and Yiqui Lu have been involved.

Diocesan School Centennial Building

Having used precast concrete on numerous other commercial and industrial projects the architects elected to use precast concrete as the principal cladding for the Centennial development to be able to provide a building appropriate to the traditions and qualities of Diocesan School.

It was clear from previous work already completed at the school, also a precast concrete building (the junior school) and from other buildings on site, that Diocesan would not be receptive to a building outside the established style, or to using some of the lighter weight cladding systems currently on offer. By careful consideration of panel size, joint location and the use of both horizontal and vertical rebates a virtually seamless building has been provided.

The use of the precast elements has also enabled modelling of the façade, creating deep recesses to the windows and the doors, and to provide cornices, projections and other details which provide an interesting pattern of shadows during the day, as the building follows the curve of the tree line.

The precast decorative columns to the perimeter extended through two levels and weighed up to 12 tonne each. They were capped off with curved precast feature beams up to 1500mm in depth. As the beams and columns included three-dimensional architectural features the detailed design, construction and placing of these components was absolutely critical in order to achieve the architect's final details.

The success of this major stage of the project was attributable to the attention to detail achieved by Wilco Precast, the engineers, architects and the construction team at Argon in putting together a high quality precast concrete structure. This was a working site with little construction space, requiring a high level of tolerance by all parties and the result is a credit to all concerned.

Motorway Noisewalls

Building Contractor:


Litecrete noisewall barrier panels have many advantages over competing materials which can deteriorate, delaminate, lose strength, deflect and may not be able to withstand vehicular impacts. Installing Litecrete noisewall barrier panels is easy. Lifting eyes are set in the top edge of the panels during the casting process and once delivered to the construction site the panels are lifted up and slotted into the galvanised steel supports. Litecrete panels may be coloured by using integral colour pigments or by staining once the panels are installed. Textures or designs can be economically created on the traffic side or the residential side of the panels using rubber formliners.
