Hazards

Potential hazards include, but are not limited to:

• Electrocution
• Damage to services
• Localised flooding
• Fire / explosion
• Uncontrolled release of gas.

Planning

Existing services including gas, electricity, stormwater, water, telecommunications etc. must be identified by MPX project management , prior to the commencement of work on the project.

Consideration must be given to employing a service locating subcontractor to identify existing services and develop a site services plan.

S All works adjacent to any identified services must be risk assessed and controls implemented.

Local authorities, services or suppliers must be consulted with, in respect to their service, prior to any site activity. Each service must be managed in accordance with local authorities, services or suppliers rules, regulations and permits or other requirements.

R All services temporary or permanent must be surveyed and identified /recorded on site plans.

The following must be considered when planning for temporary site services and facilities:

• MPX Project size, complexity, construction methodology
• Contractual and industrial requirements
• Regulatory requirements
• Completed building requirements e.g. service locations, redundancy, and potential for use in permanent services, quality and warranties.

R Site services plans must be developed by MPX and be available at the site office.

Dial before you dig information must be reviewed prior to commencing any project.

Temporary Electrical Installations (Including lighting)

Refer to Section: Electrical

Operational

Prior to commencing any work activities that have the potential to impact site services, subcontractors must consult with MPX and review site plans/as built drawings.

R The location of all site services must be identified and illustrated on the site plans / as built drawings.

S Where the location of any service is in conflict with the work activity then the applicable SWMS must include reference to the service and the control measures to be implemented.

• All people involved with the work must be inducted into the applicable SWMS.
• WMS must be reviewed by MPX prior to the commencement of the work.

P A permit to work Excavation must be implemented prior to the commencement of excavation work.

R Where a subcontractor is responsible for installing new in-ground, temporary or permanent, services, the services must be clearly marked on the site plans / ’as built’ or ‘as con’ drawings as soon as practicable following the installation of the service.

R MPX in conjunction with subcontractors must maintain and keep up to date the site services plan.

All MPX or subcontractor underground installed services must be identified with appropriate markers (surface and subsurface ie. identifier tape, as applicable) bedded with the appropriate materials and backfilled in accordance with the applicable specifications/standards. Note: Where services are bored they are required to be marked on the site services plans.

• E.g. AS/NZS 2648.1 Underground wiring –identifier tape must not be more than 200 mm above the wiring system but no less than 100 mm below the surface and where practical the excavation should be backfilled with an identifier material.

R Requirement for any shutdown of service must be notified, in writing in advance. The shutdown is not to proceed without approval from MPX.
