Thames Water has gone out to tender with an AMP7/8 framework contract for non-infrastructure MEICA and Civils medium project work with an estimated maximum value of up to £500 million.

The water company is procuring delivery capability for non-infrastructure projects - Thames recognises non-infrastructure as nominally all above ground plant, equipment, structures and process.

Expected scope of works covered by the contract spans Thames Water's water and wastewater non-infrastructure treatment assets across the Thames Water region.

Non-infrastructure scope includes refurbishment, replacement and provision of new potable water and wastewater treatment assets including service and storage reservoirs.

Wastewater non-infrastructure scope includes:

• refurbishment, replacement and provision of new treatment facilities such as inlet works
• storm water storage
• event duration monitors
• settlement tanks
• biological treatment, tertiary treatment, sludge treatment including thermal hydrolysis process (THP)
• digester roof replacement

The contract is being tendered in two separate Lots:

• Lot 1 Non-infrastructure MEICA Medium Project Works (£167,000,000)
• Lot 2 Civil Medium Project Work (£167,000,000)

Thames Water has four workstream runways:

• RW0 - Small Project Work where works contracts are expected to typically be greater than £250k in value.
• RW1 - Non-Infrastructure works with values between £250k and £5m
• RW2 - Framework Agreement (Thames wide and geographic) for Infrastructure and Non-Infrastructure works with value ranging between £5m and £25m
• RW3 - Major Projects for works with generally exceeding £25m

It is intended that Thames Water will generally allocate works contracts with a value of up to £1.5m directly to the framework contractors i.e. contracts will be shared between the framework contractors without a mini-competition.

The aggregate value of contracts directly allocated to each framework contractor over the contract term is intended to be the same.

Initial contract term is 4 years, with extension options available up to a maximum further 4 years.
