Water networks

Quantity surveying and claims support for water mains, pumping stations, storage and supply infrastructure.

Commercial challenges and how we approach them

Water network projects connect treatment and storage assets to the places they serve. Construction can include mains, pumping stations, tanks, crossings and reinstatement. Network works need to be distinguished from treatment process installations and from activities undertaken by the asset owner. Irrigation schemes can be assessed on the same clear package basis, with pumping, distribution and reinstatement separated by work area.

Pressure testing and disinfection before connection

The Challenge

A new main may be installed but unable to connect until pressure tests, disinfection and water-quality results are satisfactory. Failed or expired testing can require flushing, repeat samples and additional attendance.

Our approach

We establish the tests and connection evidence included in the package. If flushing or sampling must be repeated, the reason matters: a failed result, a missed connection window and a changed requirement are different circumstances. Test, access and instruction records help determine whether the extra attendance is original work, rectification or a properly supported addition.

Live-main connections and supply continuity

The Challenge

A moved live-main connection window can leave specialist crews waiting and temporary supplies operating for longer than planned.

Our approach

We record the agreed shutdown assumptions and readiness obligations. Actual access and plant records support an assessment of additional attendance and temporary supply costs under the relevant package.

Route changes, crossings and reinstatement

The Challenge

Different ground levels or utility clashes can change pipe depths, thrust restraints, crossings and highway reinstatement. A rate per metre may conceal substantial differences between route sections.

Our approach

We measure the revised route and check crossings, chambers and restraints separately from the base pipe-laying rate.

Adoption records and staged development handovers

The Challenge

A network can be serving occupied plots while later phases and adoption records remain unfinished. Physical use, contractual completion and adoption may occur at different times.

Our approach

We keep a phase-by-phase account of completed work, missing evidence and outstanding repairs. Payment and adoption charges are then reviewed against the actual requirements rather than assuming that an occupied development means every obligation has been discharged.
