Technical Info

Concrete

40 MPa ,low shrinkage , super-plasticised mix . We can and do use variations on the mix depending on requirements such as:

 

* Lightweight aggregate

* Styrene foam beads

* Coloured oxides

 

Hydraulic Mould System

(Australian patent no: 741667)

 

Fully automated and hydraulically operated system that can be used many times over.

 

It re-sets itself for daily use to within 2mm accuracy every time.

 

It has been designed to be “fool proof” so that the harshest site conditions will still enable a module to be poured on a daily cycle.

 

Penetrations/Openings

Can be cast into the module (preferred) or cut out later.

 

The design of each module includes the main reinforcement around the perimeter of the roof slab and around each vertical corner to form the columns. The space between the columns and below the main beams can be removed to suit various configurations – doors, windows etc.

 

The roof slab can also be moulded for stair openings, skylights, services ducts, lifts and other penetrations.

 

Production Program

One module per day/per mould is possible. Production can commence approximately 1 week after shop drawing of the individual module is approved .

 

No propping, caulking or brackets are required in the installation process.

 

Flexibility is allowed in door and window openings to suit design requirements

 

A detailed production program is produced for every job to ensure critical path and an on site programs are met.

 

Acoustic & Thermal Ratings

Superior acoustic & thermal ratings are achievable especially when placing units adjacent to each other.

 

Most accommodation classes of building acoustic and thermal requirements can be achieved with our standard build details.

Research & Development

The company is committed to a continual R & D program to ensure adherence to the ever changing building code requirements and different types of applications.

 

In particular we are working on acoustic and thermal improvements, coloured concrete finishes, polished and sandblasted finishes, lifting and unloading techniques.

 

Transport & Installation

Each module is transportable by semi-trailer and can be delivered to any site that is accessible by standard trucks. A standard 50Tonne crane is required to unload and install the modules. Most large towns have these cranes available.

Design

The basic design for the modules was undertaken by Connell Wagner using finite element analysis to optimise the use and placement of steel.

 

The basis for the design including calculations and design assumptions is contained in the document below. It is available for download here as: Generic Connell Wagner 2 storey design calcs – Nov 03.pdf.

 

The configuration of the modules in this document includes a 50mm wall section in the penetration zone. This feature has since been discontinued and now the wall thickness is universally 90mm, adding some conservatism to the design.
