Structural Audit

February 2013

Prepared for: Nick Hunter Macro Plan Dimasi LVL 4, 39 Martin pl, Sydney, NSW 2000

Prepared By: Craig O’Neill Structural Engineer Reviewed By: Bryan Cossart Principal



Executive Summary We have visited the old Canberra brickworks in Yarralumla to assess 14 existing structures from a structural viewpoint and to recommend ‘make safe’ remediation works to preserve the condition of the buildings and possibly allow limited public access. We have also suggested remediation works to simply preserve the buildings as they are in a safe condition whilst not allowing public access. We have not reviewed the condition or construction of the buildings with regards to the National Construction Code (NCC) or relevant Australian Standards. Our recommendations have been based on a visual assessment and for the basis of costing purposes only. Prior to any works being carried out a detailed analysis and design of any remediation should be carried out. The buildings are performing well for their age with the main concern being the condition of the masonry in the Staffordshire and Hardy Patent kilns. There are signs of movement and cracking throughout the entry archways and tunnels in most areas. There are also areas of loose brick overhead which pose a risk for any proposal for public use. In our remediation works we have provided sketches which utilize steel arch frames to reinforce the brickwork. We have also provided steel struts and mesh in order to hold brickwork in place where loose. We have also highlighted areas where structural bracing has been removed in order to allow access for the current and past tenants of the buildings. We have recommended that these be replaced to restore the building to their original design intent. Some elements of steel including trusses and columns have been damaged by what appears to be impact by vehicles. We have provided details to restore these members to their original condition. There are areas of deteriorated timber due to water ingress and exposure to the elements. In most cases these are minor structural elements which include linking walkways and awnings. We have nominated that the walkways be restricted from public access for any future use. Awnings should be made safe by securing loose connections and removing or replacing collapsed elements. All buildings should also be made water tight to prevent further deterioration of the building fabric. Our recommendations should be considered as short term and will need to be reassessed periodically to ensure their effectiveness.

1.0 INTRODUCTION As requested we have attended the old Canberra brickworks in Yarralumla to report on structural measures necessary to make the various structures safe and thereby slow and deterioration due to wind, rain, gravity or similar forces on the buildings. Our review has been visual and we have not commented on the concealed elements of the structures. We have provided two levels of remediation as follows:

Public access option – ‘Make-safe’ works to maintain the buildings in their present condition and allow limited public access to buildings where possible for interpretive purposes.

No public access option – ‘Make safe’ works to maintain buildings in their present condition with no public access.

We have provided pragmatic remedial works of a short term nature that will require ongoing auditing to reassess their effectiveness. The buildings inspected on site included;

Building 1: Power house

Building 2: Downdraft Kilns

Building 3: Staffordshire Kiln (kiln 1)

Building 4: Hardy Patent Kiln (kiln 2)

Building 5: Hardy Patent Kiln (kiln 3)

Building 6: Chimney stack

Building 7: Machine bays I and II

Building 8: Workshop

Building 9: Machine bay 1

Building 10: Machine bay 2

Building 11: Large crusher house

Building 13: Fan house

Building 14: Fan house

Building 15: Brickyard building

Miscellaneous structures A site map showing the location of these buildings can be found in Appendix A. We have not reviewed the design, condition or construction of the buildings to be in accordance with the National Construction Code or Australian Standards. We have only assessed them visually to provide a formed opinion of the structural condition. These assessments and remediation works have been conducted with the view that annual inspections will be carried out to routinely review the condition of the structures, and to assess that the measures put in place are still relevant.

1.16 Miscellaneous Structures



Conveyor and Truck hopper Site Observations

Structures located in the NE corner of the site.

Both structures are steel framed and are performing well.

Hopper yard has a timber framed floor which is weather damaged and unsafe.

Remediation Requirements It is understood these structures will not be utilized in the future plan for re-use. If these structures are not demolished, they should be cleared of any fallen debris and fenced off from public access. Open drainage Trenches Site Observations

There are approximately 620metres of drainage trench located throughout the site.

Drains are open in some cases and in others the covers are warped and are currently trip hazards.

Remediation Requirements In most cases the drains require new covers to prevent the trip hazards.

Damaged retaining wall Site Observations

The retaining wall located between building 9 and 8 is approximately 4 metres high; constructed of approximately 3 metres of concrete and 1metre of masonry.



The concrete section of the wall is in reasonable condition.

The masonry portion of the wall is badly damaged and collapsed in some areas.

There is a large tree which has become unstable due to the collapse of the wall. Remediation Requirements


Damaged retaining wall

(Figure 30)

Collapsed brickwork on the upper section of the retaining wall and retained soil should be removed. The three should also be removed before it becomes too large and collapses. Earth should be battered at 45degrees away from the top of the wall.

Collapsed brickwork on the upper section of the retaining wall and retained soil should be removed. The three should also be removed before it becomes too large and collapses. Earth should be battered at 45degrees away from the top of the wall.

Treatment of adjacent buildings

The adjacent buildings (building 9 and other unreferenced building) should be monitored during the demolition. Refer to building 9 for details. The unreferenced brick building should either be demolished during the wall removal or underpinned.
