Overview

In October 2019 AT commenced a procurement process to source a lead design consultant to provide a re-design that would allow improvements to be made to the existing EMU graffiti wash facility at the Win EMU Depot. These improvements are essential for maintenance of EMU rolling stock and the health and safety of staff who clean and maintain the EMU trainsets. The project mandate specified the following three improvements:

1.Improvements to body repair and cleaning (including EMU roofs) facilities. Appropriate servicesupplies (e.g. water and compressed air) are currently lacking and there is no safe provision to allowfor cleaning at height.
2.Construction of a post incident cleaning pit. No facility currently exists.
3.Facilities to enable EMU paint spraying

Items 1 and 2 are considered most critical and achievable to construct with detailed design well progressed and relevant Building Consents applied for.

Wash Bay Extension:

The proposed cleaning solution requires a single building capable of fully enclosing one carriage, by providing an extension to the existing structure.

The scope of this work includes:
•Erection of a new 5m long steel portal frame to extend the current building
•High level platforms on either side of the existing building and extension to allow roof cleaning ofcopper oxide and carbon, with access stairs, safety rails and harness attachment points to facilitateroof cleaning.
•Hose outlets and compressed air outlets
•A self-draining floor with a soil separation sump leading to a trade wastewater system.
•Upgraded electrical systems in the current building
•Upgraded sprinkler systems in existing building along with installation in the extension.

Post Incident Pit:

This will be provided in a standalone area alongside the existing building. The scope of work includes: -
•A bio-cleaning pit approximately 30m long for cleaning the undercarriage and bogey of the trains.
•Steel roof and walls to enclose the pit
•A self-draining floor with a soil separation sump leading to a trade wastewater system. The sump canbe isolated for forensic inspection, prior to discharge to trade wastewater system and the drainagesystem includes a vertical pump to take account level differences.
•Low-pressure water hose tap points.
•Compressed air points.
