1 PREFACE

The aim of this procedure is to have appropriate measures in place to minimize the risk of

harm to persons undertaking excavation work, damage to PPA underground utilities and

outages to the business, due to utility services being disturbed.

2 OBJECTIVE

Underground services have been installed, moved and removed throughout the Port since

1960. Due to various reasons PPA cannot guarantee the accuracy of utility drawings in its

possession.

The objective of this procedure is to ensure all excavation work deeper than 150mm is

notifiable to relevant PPA staff and all measures have been taken to reduce the risk of harm

or damage.

3 SCOPE

To ensure all PPA personnel and contractors understand the requirements of the Port

Authority in relation to any excavation work that has the potential to be deeper than150mm.

To provide a set of actions to approve and Permit any excavation work deeper than 150mm

regardless of method.

and is seeking to specifically:

a) undertake excavation of material and move the material from its current location;

and/or

b) move an existing stockpile of material to another location within or outside these Lots,

then the site Environment team must be notified immediately and the following

conditions will apply. Note that material must not be moved from the excavation

location until all of the below conditions have been satisfied:

A soil sampling and laboratory analysis plan must be developed by the Applicant to

demonstrate the contamination status of the material. This plan shall be prepared in

accordance with the Western Australian Department of Environment Regulation

Landfill Waste Classification and Waste Definitions (as amended) and Environment

Protection (Control Waste) Regulations 2004 (where relevant). As a minimum, the

plan shall outline the total estimated volume of material, a site map showing the

location of the material, the number of samples required and where/how they will be

collected. The plan shall also state that sampling will be conducted by competent

personnel, and all samples will be independently tested at a NATA accredited

laboratory. The plan shall be submitted to the relevant PPA Environment and

Heritage team for review and written approval.

9 SAFE WORK PROCEDURE AND CODE OF PRACTICE

The permit holder has to comply with PPA Safe Work Instruction – Excavation Work.

The Code of Practice is published by the Commission for Occupational Safety and Health,

Government of WA and is available on this website:




A22895 of 13

The Code (page iii) applies to: “all workplaces in Western Australia covered by the

Occupational Safety and Health Act 1984 where excavation occurs, and to all persons with

the potential for exposure to hazards resulting from excavation in those workplaces,

including:

All areas where equipment is used to excavate; and

All areas where processes associated with excavation are undertaken”.

The Code “provides guidance to prevent occupational injury and disease in all workplaces

where excavation and associated earthworks are performed” (page iii).

PPA expects that the appropriate practices from this Code of Practice will be observed by the

permit holder.

10 COMPETENT PERSON

As the nature of excavation work varies from simple excavations to complex ones, the

approved contractor representative holder must ensure that the excavation and/or related

works are carried out or supervised by a competent person.

A competent person, as defined in section 1.3 of Occupational Safety and Health

Regulations 1996, is “one who has acquired through training, qualification, or experience, or

a combination of those things, the knowledge and skills required to do that thing

competently.”

It is expected that the knowledge and skills expected from a competent person “will increase

as the complexity of excavation increases” (page 13 of the Code of Practice).

11 RISK ASSESSMENT AND SAFETY WARNINGS

This condition reiterates the importance of Health and Safety of workers and the public in all

areas within the jurisdiction of Pilbara Ports Authority.

PPA expects that an approved Job Safety Analysis is in place prior to any excavation

works taking place.

During the duration of the approved works, the permit holder shall put in place all the

appropriate warnings to the public and signage on safe access and egress to the area to be

excavated. The signs shall be displayed to persons in or entering the area. All excavations

that are to be left open overnight must have additional warning devices such as flashing

lights in addition to existing barricading, access tape and tags and signage. The appropriate

signs shall comply with and shall be used in accordance with AS 1319-1994: Safety Signs

for the Occupational Environment.

Issuing Officer as acknowledgment that all works have been completed and site left in a

clean and safe condition. PPA has the option to inspect the site on completion and may

15 CANCELLATION OF PERMIT

PPA can cancel this permit at any time if the permit holder is found to violate the

conditions of this permit. The appropriate disciplinary actions may also be taken against the

permit holder, if required.

16 UNKNOWN SERVICES

undertaking excavation works. However, many of the drawings of services are old and

their location may be approximates only. Additionally, older services may not be shown on

any drawings.

All excavations are to proceed with care. Where unknown services are found, work is to

cease immediately and the Pilbara Ports Authority advised to allow for further inspection.

PPA’s Electrical Supervisor or Civil Supervisor is to be notified when in ground service

locating is required on the East Harbour and the Mechanical Engineer or Electrical
