# Wind

Quantity surveying and claims support for construction packages on onshore and offshore wind projects.

## Commercial challenges and how we approach them

Wind construction includes foundations, access, installation support and electrical connections alongside turbine supply. Onshore work can involve extensive routes and site preparation; offshore packages add marine installation and mobilisation interfaces. Each appointment needs a defined construction scope and payment basis.

### Turbine changes reaching foundations and access

#### The Challenge

Changing the turbine can change the foundations, crane pad and delivery route as well as the purchase price.

#### Our approach

We assess the selected machine's requirements across civil, transport and installation packages. Orders already placed, cancellable items and superseded work all matter. This gives the client a view of the total change before a turbine substitution is accepted on its headline cost alone.

### Weather windows and vessel or crane standby

#### The Challenge

Offshore installation depends on suitable sea conditions and vessel availability; onshore lifts also depend on weather and crane readiness. Missed windows can create substantial standby or remobilisation claims.

#### Our approach

We read the weather and standby provisions alongside daily weather, plant and readiness records. A vessel unable to work because of sea conditions is a different case from one waiting for a late component during workable weather. Separating those causes is essential to assessing a standby or remobilisation claim.

### Cable installation and turbine-package interfaces

#### The Challenge

A missed cable pull-in or termination can hold up another contractor's installation and testing. Competing attendance claims can then refer to the same lost period.

#### Our approach

We make the interface dates and attendances visible in the commercial schedule. Where a dependency fails, we trace the affected activities and costs to the relevant records rather than attributing all delay to the final connection.

### Abnormal-load routes and temporary access

#### The Challenge

Onshore turbine deliveries can require road alterations, temporary bridges, land access and restoration. A changed route or component size may increase work outside the wind-farm boundary.

#### Our approach

We measure authorised route and access changes by location, checking the land commitments and crediting enabling work no longer needed.

### Offshore fabrication and installation readiness

#### The Challenge

Offshore installation slots bring fabrication, port handling and a booked vessel together. A late component can lose the slot; an unavailable vessel can leave components in storage. The costs may look similar, but the cause and contractual responsibility are quite different.

#### Our approach

We compare fabrication, port and installation commitments before award. In a dispute, we distinguish the cause of lost slots from the resulting storage, standby and remobilisation costs, testing each against the contract.
