Construction: Sceneview

Scenario – Sceneview owns land and contracts Projex to build a warehouse. This scenario looks at securing interests in goods that are ‘commingled’ ...

Concepts covered:

  • PPSR registration
  • priority rights
  • commingling.

The scenario

Developer Sceneview owns land on which it has permission to build a warehouse.

It contracts with Projex to build the warehouse. The contract provides that Projex sources the material needed for the build process.

Projex will submit monthly invoices to Sceneview for works and materials, whether the materials are on-site or off-site.

Sceneview has a security interest, under the contract, in all building materials in the possession of Projex, to secure performance of Projex’s obligations under the warehouse contract.

Sceneview registers that security interest against Projex on the PPSR.

Back at Projex’s yard, it mixes sand and cement to make mortar, which it then prefabricates into composite steel–concrete girders for the warehouse. It invoices Sceneview for the sand and cement that month.

One year later, Projex goes into liquidation with the girders still in its yard.

Seven months before liquidation – after the Sceneview contract was signed and after Sceneview had registered on the PPSR – Projex’s bank registered a security interest over all of Projex’s present and after-acquired property to secure its general lending to Projex.

Because Sceneview registered its security interest on the PPSR, it can claim the value of the sand and cement because Projex defaulted on the secured obligations to perform the contract. Sceneview has a priority interest in the materials as commingled in the ‘girders’.

Sceneview registered before Projex’s bank, so it takes priority over the bank for the sand and cement.


The PPS Act strengthened the position of developers like Sceneview. Now it can claim a security interest in materials in the possession of the contractor, even those made into a new item that has not yet been incorporated into Sceneview’s building.

It does not matter that the materials have been incorporated by processing with steel into girders – a security interest continues where goods are ‘commingled’ by processing or manufacturing into something new which loses its original identity.

Registration helps to ensure protection should the contractor go insolvent, and/or another financier registers an interest in the components or the whole new thing. (Note- once incorporated into the building, Sceneview would own the materials as fixtures.)


This is a general scenario intended to provide typical examples.
