History - RMIT University, Building 24 La Trobe St Facade Treatment

Foresters’ Hall was completed in 1888 for the Ancient Order of Foresters (AOF) by the architects George Ravenscroft and Freeman. The building remained in use as the AOF headquarters until the 1960s when it was purchased by the Victoria Education Department for RMIT’s Student Union. A notable example of the many public and private institutions established during the 1880s and is indicative of the prominent role played by friendly societies in the development of Melbourne during this period

External Finishes History....

The Façade has had a number of paint finishes applied over its 125 year history.

The most recent is an Deep Indian Red with contrasting cream painted window arches

In some areas up to 9 different layers were revealed

the original render finish was of a natural grey stone colour

The façade analysis also revealed the use of a variety of colours to highlight the decorative elements on the façade. This included gold leaf lettering and ultramarine blue which was used to define the coats worn by the figures within the Coat of Arms. The recent investigation of the paint layers and render identified the occurrence of lead (Pb) in the applied paint finish

Low levels of lead contamination where also found in the render layer, however the levels are sufficiently low that they are considered to not pose a risk under the current Australian Standards

Doing the paint homework

Examples of the Ancient Order of Foresters’ Crest “There are a number of versions of the AOF coat of arms which could be adopted should the decision be made to proceed with highlighting this and other decorative elements.”

RMIT – Heritage Restoration

Identified hazardous paint materials are to be removed under controlled conditions.

The façade, window surrounds and door frames are to be restored.

Scope

Permit requirements

Scaffolding assembly

Pedestrian traffic management

Hoardings

Restricting access to the containment zone,

Provision of relevant warning signage

Appointment of a coating inspector must also take

place for inspection and testing of the protective

coating system.

Time

The project started back in October 2014 with an anticipated completion date of Dec 2014 'The restoration would include the removal of several layers of lead paint within a contained zone

On completion of the lead removal a larger render issue was identified during the start of the works which changed a significant part of the contract which ended taking the project from 3 months to 10 months completion

Risk Full encapsulation and ongoing testing of airborne particle were now required through the entire paint removal process

To minimise airborne particles that would affect the public and students alike we proposed a smart spray applied paint removal system .............
