Water treatment

Quantity surveying and claims support for drinking-water treatment facilities and associated construction packages.

Commercial challenges and how we approach them

Water treatment projects combine process structures, tanks, buildings and pipework with mechanical and electrical installations. New facilities and upgrades may require staged connections to the water network. Construction, equipment supply and process requirements need identifiable package interfaces. Desalination facilities also require clear boundaries between process equipment, civil works, intake or outfall connections and network installations.

Upgrades while drinking-water production continues

The Challenge

Replacing a filter, pump or treatment stage may require a phased shutdown and temporary supply arrangements. Reduced access or an altered sequence can extend temporary plant and specialist attendance.

Our approach

We agree the phased shutdown and temporary-supply assumptions used for pricing, then compare them with actual releases. If a filter or pump replacement must be split into further stages, the assessment identifies the extra setup and temporary plant involved. Those costs are kept separate from changes to the permanent treatment equipment.

Process equipment and civil-tank interfaces

The Challenge

Late filter or membrane-supplier details can change tank openings, pipe connections and concrete already committed.

Our approach

We reconcile vendor requirements with the priced civil and mechanical packages. Each revision is assessed across the affected work, separating additional scope, omitted allowances and substantiated rework.

Water-quality testing and commissioning inputs

The Challenge

A treatment installation may need specified cleaning, testing and operating conditions before acceptance. Unavailable raw water, chemicals or connected systems can prolong testing even where the equipment is installed.

Our approach

We clarify who provides raw water, chemicals and other test inputs. Technical test records then help separate extra attendance caused by unavailable conditions from work needed to fulfil the original acceptance requirements.

Controls and existing-plant integration

The Challenge

A package can work on its own but still fail to communicate with the existing works. Signals, software changes and integration tests need a clear owner across the supply and installation orders.

Our approach

We check those interfaces before award and assess later changes against the agreed integration scope, including any evidenced repeat attendance.
