Hammerhead Crane, Garden Island, Sydney—Archival Recording Report—Stage One (Prior to Removal), October 2013 1

1.0 Introduction

Godden Mackay Logan Pty Ltd (GML) has been commissioned by Brookfield Johnson Controls

(BJC) on behalf of the Department of Defence (Defence) to provide heritage services relating to the Hammerhead Crane removal project, including undertaking the photographic archival recording for

the Hammerhead Crane prior to and during its removal.

This report has been prepared to provide evidence to the Department of Sustainability, Environment, Water, Populations and Communities (DSEWPaC) that an archival recording (in

accordance with condition 8(a) of the approval) has been undertaken prior to the commencement of

removal works. This report includes photographs of the Hammerhead Crane from surrounding

vantage points, photographic archival recording images of and on the crane, and a representative

selection of three dimensional laser scan images.

1.1 Background

In 2012, Defence commissioned Parsons Brinkerhoff and Brookfield Multiplex to prepare an EPBC

Act Referral for the removal of the Hammerhead Crane. Defence determined that the proposed

removal of the Hammerhead Crane was necessary to allow Garden Island to provide training and logistic support, maintenance facilities and berths for major current and future Royal Australian

Navy (RAN) ships home-ported in Sydney, as well as additional berths for other visiting RAN and

foreign warships.

On 15 June 2012, Defence submitted a Referral under Section 68 of the EPBC Act for the removal

of the Hammerhead Crane at Garden Island, FBE Sydney, New South Wales. On 12 July 2012, the

proposed action was determined to be a controlled action by DSEWPaC and as such was required

to be assessed by Preliminary Documentation (EPBC Decision 2012/6430).

On 17 July 2013, the Department of Defence (Defence) received approval from the Minister of

DSEWPaC to remove the Hammerhead Crane located at Fleet Base East, Garden Island, New

South Wales (EPBC 2012/6430).

A series of conditions of consent were stipulated with the approval. Condition 8 stated that:

8. The person taking the action must engage a suitably qualified expert to undertake an archival recording of

the Hammerhead Crane. The archival recording must:

a) provide an accurate record of the Hammerhead Crane as it exists prior to demolition;

b) provide an accurate record of the physical dismantling of the Hammerhead Crane;

c) record all elements or vantage points of the Hammerhead Crane, as identified in accordance with

condition 7(a) of this approval;

d) include (but not necessarily be limited to) photographic recordings, video recordings, and three

dimensional laser scans; and

e) be undertaken in accordance with the measures specified by the relevant NSW guidelines including,

‘How to Prepare Archival Records of Heritage Items’ (prepared by the NSW Heritage Office, 1998).

The archival material must be collated in both digital and physical format that is easy to view and handle, and

that ensures any photographs are unlikely to be damaged in the long term.


Evidence that the archival recording under condition 8(a) of this approval has been undertaken must be

provided to the Department prior to the commencement of removal works.

Evidence that the archival recording required under condition 8(b) of this approval has been undertaken must

be provided to the Department within one month after having been undertaken.

An accurate record of the physical dismantling of the Hammerhead Crane (in accordance with

condition 8(b) will be undertaken by GML, Hyperion Design and RPS Group during the removal

process (estimated to occur in late 2013/2014). This will include photographic, time-lapse, video

and 3D capture. These will be collected in hardcopy and softcopy formats, and presented the

Archival Recording Report which will be provided to DSEWPaC within one month after having been undertaken.

GML, in collaboration with Hyperion Design, is undertaking photographic and video archival

recording in accordance with condition 8(d).

• The photographic and video archival recording will be undertaken and presented in

accordance with condition 8(e); ie in accordance with the NSW Heritage Council Guidelines – ‘How to Prepare Archival Records of Heritage Items’, and ‘Photographic Recording of Heritage Items Using Film or Digital Capture’ (as referenced in the Defence Heritage Toolkit,

Factsheet E: Archival Recording of Heritage Assets).

RPS Group will be undertaking the three dimensional laser scan of the Hammerhead Crane in

accordance with condition 8(d). GML has not been involved in the actual 3D scanning of the

Hammerhead Crane, however, GML will include the RPS Group output in the Archival Recording

Report.

2.0 Vantage Points

2.1 Identification

The following section incorporates material originally prepared by GML for the Heritage Impact

Assessment (HIA) for the removal of the Hammerhead Crane (dated October 2012). To meet the specified requirements for the 2012 Heritage Impact Assessment (which included a visual impact

assessment), the GML project team:

• determined public domain vantage points (shown in Figure 2.1—Vantage Points Map), which

were confirmed by Defence as suitable;

• undertook a site visit on 12 and 13 September 2012 to view and photograph the

Hammerhead Crane in its context;

• undertook photography from the harbour to access the key publically accessible locations

including from commuter and recreational watercraft routes and wharves;

• undertook photography from land-based vantage points which are publically accessible and

popular for tourists and visitors; and

• prepared a table with a photograph from each of the 26 vantage points, including a brief

explanation of the location and the view to the Hammerhead Crane.

Twenty-six vantage points were selected, in consultation with Defence, to illustrate the visual

catchment of the Hammerhead Crane from within and around Sydney Harbour.

The criteria used to select the most relevant vantage points included:

• quantity of observers and duration of observation generally by residents, local Sydney-siders,

tourists for site-seeing and other recreational user;

• visibility/visual prominence of the Hammerhead Crane (including skyline view, backdrop,

screening, etc); and

• accessibility to public land with harbour views and roads and the harbour (for ferry

commuters and leisure craft).

The position of these vantage points was then refined using a combination of topographic map

interpretation and exploration of the surrounding areas by car and on foot, to confirm the most

appropriate locations for photography.


Figure 2.1 Vantage points used in the visual impact assessment (Source: Google Maps. Graphics: GML)


2.2 Representation

Refer to the associated map, Figure 2.1, which indicates the location of the vantage points. The

vantage points were chosen because of their public accessibility both from the harbour (referred to as views from the ‘water level’) and from the land or harbour edge.

In the following, table there is a photograph of the Hammerhead Crane from the vantage points and

a description of the view to the Hammerhead Crane in order to make identification easier.

3.0 Photographic Archival Recording

3.1 Methodology

The photographic archival recording was undertaken in accordance with the NSW Heritage Council Guidelines – ‘How to Prepare Archival Records of Heritage Items’ and ‘Photographic Recording of Heritage Items Using Film or Digital Capture’ (as referenced in the Defence Heritage Toolkit,

Factsheet E: Archival Recording of Heritage Assets). Only digital capture was undertaken. Film

capture was not undertaken.

The photographic archival recording is being undertaken in a staged approach:

• Stage 1 (Prior to Removal)—was undertaken in June and July 2013, prior to the

commencement of removal works;

• Stage 2 (During Removal)—will be undertaken in late 2013 and 2014 (to be confirmed); and

• Stage 3 (Post Removal)—will be undertaken in late 2014 (to be confirmed).

Kylie Hilton and Grant Christian undertook the photography for Stage 1 over several site visits

during June and July 2013.

The photography included contextual shots of the Hammerhead Crane from Garden Island and

from surrounding vantage points, and detailed shots of components of the crane. Generally the

shots included:

• contextual shots from Fleet Base East, Garden Island and surrounds (eg Woolloomooloo

Wharf and Mrs Macquaries Chair);

• ground level views up to and elevations of the crane;

• detail photographs of the crane (generally) via access directly onto the crane;

• detail photographs of components (such as jib, motor room machinery, slew houses and live

ring); and

• process photographs of the changing of the safety and catch platforms located under the jib

of the Hammerhead Crane.

3.2 Equipment

The photographs were captured using a medium format SLR digital capture. Below is a list of the

standard pieces of equipment used on this project. In some cases, only a selection of the items

listed were utilised, however, all were available if required.

• Cameras: Canon 7D Digital SLR (18.1 Megapixel), Canon 40D Digital SLR (10.2 Megapixel)

and Canon 20D Digital SLR (8.2 Megapixel).

• Lenses: 10mm, 50mm, 18mm-200mm, 20mm-35mm, 28-80mm, 70-300mm and Perspective

Correction.


Hyperion Design

• Camera Accessories (as required): Tripod, Flash Units, Scale Rod, Filters (polarising etc) and

Cable and Remote Releases.

3.3 Deliverables

Photography in Stage 1 resulted in 313 photographs of the Hammerhead Crane being captured.

The photographic material is supplemented by a photographic catalogue containing a description of

each image taken and associated reference plans illustrating the position each image was taken

from.

The photographs and photographic catalogue have been compiled in a folder along with three CDs

containing the JPEG and Canon Raw Image (CR2) file format soft copies of the photographs.

Note: All digital images are printed to archival storage requirements as set out in the NSW Heritage

Branch guidelines. All papers and inks used in the folder are acid-free and use archival stable inks.

The deliverables for this stage of works (Stage 1) will also be collated with the deliverables for the following stages of works (Stage 2 and 3) to form part of the ‘Hammerhead Crane, Garden Island, Sydney—Archival Recording Report’.

3.4 Repository

At present, three sets of the Stage 1 folder have been produced. Further copies can be produced when the final repository requirements have been determined.

In accordance with condition 9 of the approval, the archival recording material will be made

available to the public (in perpetuity) at the Royal Australian Navy Heritage Centre on Garden Island and on the internet (location to be determined).

Physical copies are to be provided to the following institutions in accordance with condition 9;

• the National Archives of Australia;

• a local library within the vicinity of the action (City of Sydney); and

• a state or national library within the vicinity of the action (NSW State Library).

It is also advisable that one set be provided to DSEWPaC, and that one set be retained by the client (ie Defence).

RPS Group

4.0 Three Dimensional Laser Scan

This section is an extract from a ‘Work in Progress Update’ prepared by RPS Group dated 21

October 2013.

4.1 Background.

RPS Group was commissioned by Defence to provide the Three Dimensional (3D) Laser Scan of

the Hammerhead Crane located at the Garden Island Naval Base. The purpose of the 3D Laser

Scan is to provide Defence with an accurate, 3D model of the Hammerhead Crane that can be used initially as an historical record of the state of the crane at the time of the scan, and potentially for

future interpretation purposes.

Due to the nature of the crane itself and access restrictions to some areas of the crane, a two (2) stage approach to the capture was implemented:

• Stage 1 - captured the majority of the Hammerhead Crane as it stands including some of the

surrounding context; and

• Stage 2 - (yet to be undertaken) will capture elements that could not be accessed in Stage 1

due to Workplace Health and Safety restrictions or existing crane components prohibiting

clear vision and making scanning at that time not viable.

4.2 Workflow for Virtual Archival Recording

Stage 1 – Data Collection and Verification.

• Initial data capture of the crane in situ. This initial work captured the bulk of the data for the

crane, additional visits, during Stage 2, will be required to scan and capture information on

inaccessible areas.

Stage 2 – Data Processing

• Processing of the point-cloud data obtained to date. Where possible as much of the

scaffolding and non-original elements will be trimmed from the model.

Stage 3 – CAD Model Development

• Creation of a 3D CAD model of the crane.

4.3 Equipment

The first stage of 3D Laser Scanning (on site and for processing) was undertaken using the

equipment and software listed below.

4.3.1 Field Equipment

• Leica ScanStation P20:

− RIEGL VZ;

− NODAL Ninja;


RPS Group

− Pentax K5 ii medium format Digital SLR; and

− Trimble S8 1” 1mm Total station.

4.3.2 Software

• Leica Geosystems HDS Cyclone;

• RIEGL Riscan PRO; and

• PTgui.

4.4 Works Completed

4.4.1 Stage 1

As of October 2013, Stage 1 has been completed; this comprised the capture of one hundred and nineteen (119) 3D scans, the placement of two hundred and fifty six (256) reference targets and the

capture of approximately nine hundred and fifty (950) images.

Additional items will require further scanning during the deconstruction phase of this project, the core areas are listed below.

• Roller system beneath the Slew ring;

• Slew Motor Room;

• Drivers Cabin; and

• Personnel hoist.

4.5 Works to be Undertaken

4.5.1 Stage 2

Access to the Hammerhead Crane is again required during the deconstruction phase in order to

undertake Stage 2 of the laser scanning.

The initial processing of the pointcloud has been completed. Progress images of this pointcloud can

be seen in this report.

RPS Group is currently producing a Leica Trueview product of scans captured to date. The CAD

model development (Stage 3) has begun however significant progress cannot be reported at this

point.

4.6 Example Scan Images

The following pages contain a representative collections of images to demonstrate the areas of the

Hammerhead Crane that were laser scanned in Stage 1 (ie a majority of the crane and

components), and the level of detail achieved at a contextual, macro and micro level.
