Race starts for £110m Scottish sewerage works

The project, based at Daldowie on the River Clyde, will include the design, construction, delivery and commissioning of a tertiary chemical dosing plant and a granular activated sludge plant to clean wastewater.

The tender is divided across two lots of £55m, but Scottish Water has said that its preference is to appoint both lots to one bidder, based on a “most economically advantageous tender” evaluation.

In total, the project is expected to last for 18 months, while a maximum of five bidders will be invited to tender.

In April last year, Scottish Water appointed a Galliford Try, MWH Treatment and Black & Veatch joint venture as preferred bidder on its £560m non-infrastructure Quality and Standards IV framework.

Works for the framework include design-and-build projects for Scottish Water’s water and wastewater treatment programmes, including new-build projects and upgrades.

The operator also appointed an Atkins/RPS JV and a Mott MacDonald/MWH JV to its £120m consultancy framework in February this year.
