GPT cleaning methodologies

Night / early-morning works at approximately 2 am. Cordon off 10 carparks adjacent to the GPT per the site works layout. Hardstand access via footpath and kerb; keys required to remove bollards. Isolate the entire work area with temporary fencing (approx. 12 fence sections, weighted feet and clamps).

Traffic and pedestrian control to manage safe entry/exit of the vacuum truck and passing traffic. Appropriate traffic management plan and permits sourced prior to works. An exclusion zone is established with temporary fencing to prohibit pedestrian access around the asset.

Per the resource-allocation table in the signed method statement — vacuum truck and crew resourced by QEST Infrastructure.

Risk of tidal impact as the downstream headworks discharge a short distance away at Burleigh Beach. With no penstock valve to restrict backflow, all confined-space works must be undertaken during the peak low period.

Site-specific SWMS and SOP; all operators to review the SWMS and EMP and discuss the day's risks at the pre-start. Confined-space entry conducted under permit with risk assessment, entry/exit log, gas detector, harness and tripod. Working-at-heights fall-arrest (harness and extendable lanyard to certified anchor points) worn before removing access covers.

Works governed by the site-specific Environmental Management Plan (EMP) — containment, disposal and waterway protection.

1. Arrive on site during the peak low-tide window; establish site and exclusion fencing.
2. Remove access covers under fall-arrest; complete confined-space risk assessment and permit.
3. Vacuum-extract sediment and pollutants from the screening chamber and sump.
4. Service the removable bag; inspect screens and internals.
5. Reinstate covers, demobilise, and log the visit in Assetlogue with photographs.

Hardstand access via footpath and kerb, with hardstand adjacent to the GPT for the crane truck to be parked ready for use. Kerbside shoulder on Ferny Ave available for temporary parking and vehicle movements.

Traffic and pedestrian control for safe vehicle entry/exit; traffic management plan and permits sourced prior to works. Exclusion zone fenced around the asset to prohibit pedestrian access.

Per the resource-allocation table in the signed method statement — crane truck, vacuum truck and crew resourced by QEST Infrastructure.

The outlet is permanently submerged, discharging into the Nerang River, with a tide-gate valve to help restrict backflow. Book night works at the lowest tide; start as the tide is dropping to provide at least a 5-hour low-tide window. At the 0.23 m level there is approximately 300 mm of water within the outlet pipeline and partial submergence of the diversion chamber floor.

Site-specific SWMS and SOP; pre-start review of SWMS and EMP. Confined-space entry under permit with risk assessment, entry/exit log, gas detector, harness and tripod. Working-at-heights fall-arrest worn before removing access covers.

Works governed by the site-specific Environmental Management Plan (EMP).

1. Mobilise at the lowest tide; isolate site and establish exclusion fencing.
2. Remove access covers under fall-arrest; conduct confined-space risk assessment and permit.
3. Vacuum-extract sediment and pollutants from the screening chamber and sump.
4. Service the removable basket; inspect screens and internals.
5. Reinstate covers, demobilise, and log the visit in Assetlogue with photographs.

Site established and isolated per the site works layout, with hardstand access and temporary fencing to create an exclusion zone around the asset.

Traffic management plan and permits sourced prior to works; pedestrian control for safe vehicle entry/exit.

Per the resource-allocation table in the signed method statement — plant and crew resourced by QEST Infrastructure.

Tidal influence assessed for the site; confined-space works scheduled within the low-tide window as applicable.

Site-specific SWMS and SOP; confined-space entry under permit with gas detection, harness and tripod; working-at-heights fall-arrest for open-edge works.

Works governed by the site-specific Environmental Management Plan (EMP).

1. Establish site and exclusion fencing within the traffic-control perimeter.
2. Remove access covers under fall-arrest; complete confined-space permit.
3. Vacuum-extract sediment and gross pollutants from the chamber and sump.
4. Service basket/screens and inspect internals.
5. Reinstate, demobilise, and log the visit in Assetlogue with photographs.

Establish and isolate the work area around the BBQ grease trap; manage public access within a busy park environment.

Pedestrian control and signage for public park users; vehicle access managed for the service vehicle.

Per the resource-allocation table — service vehicle and crew resourced by QEST Infrastructure.

Grease and food-waste containment controls applied to prevent release; extracted material transported for licensed disposal.

Site-specific SWMS and SOP; confined-space and manual-handling controls; hygiene and PPE controls appropriate to organic waste.

Environmental Management Plan governs containment, spill prevention and licensed disposal of extracted grease and solids.

1. Establish site and containment around the trap.
2. Extract grease, solids and wastewater to the service vehicle.
3. Inspect and clean baffles and chamber; check for damage.
4. Reinstate covers and leave the area clean and safe for public use.
5. Dispose of material to a licensed facility; log the visit in Assetlogue with photographs.

Establish and isolate the work area around the OTF; secure access to tanks and chambers.

Pedestrian control and signage for park users; managed vehicle access for the vacuum/service vehicle.

Per the resource-allocation table — vacuum/service vehicle and crew resourced by QEST Infrastructure.

Effluent containment and odour controls applied; confined-space atmosphere tested before entry.

Site-specific SWMS and SOP; confined-space entry under permit with gas detection, harness and tripod; biological-hazard PPE and hygiene controls.

Environmental Management Plan governs effluent containment, spill prevention and licensed disposal.

1. Establish site and containment around the facility.
2. Test confined-space atmosphere; enter under permit as required.
3. Extract septic solids and effluent to the service vehicle.
4. Inspect tanks, chambers and components; report condition.
5. Reinstate, dispose to a licensed facility, and log the visit in Assetlogue with photographs.
