Inland waterways and waterside structures

Quantity surveying and claims support for canals, riverfront works, marinas and waterside structures.

Commercial challenges and how we approach them

Waterside projects can bring retaining structures, moorings, access walkways and utility connections into a constrained working area. Some activities take place from the bank and others on or over water. The construction packages need to identify those boundaries and the temporary access or working arrangements included in the price.

Repairs inside a booked navigation stoppage

The Challenge

A lock repair may have one booked stoppage in which to investigate, repair and reopen. Discoveries after draining can make that window difficult to meet.

Our approach

We separate the additional repair from the measures taken to protect the reopening date. Extra shifts or a second mobilisation need their own instruction and cost evidence; they should not disappear into an inflated repair rate. The tender's closure and investigation assumptions provide the starting point for assessing responsibility.

Dewatering and temporary navigation arrangements

The Challenge

Cofferdams, pumping and temporary access can be substantial parts of a waterside repair. Leakage, altered water levels or an extended programme may change their duration and attendance requirements.

Our approach

We compare the actual pumping and temporary works with the priced method and operating conditions. An extended programme does not automatically make every additional hire charge payable.

Hidden condition of locks and retaining walls

The Challenge

Lowering the water may reveal more deterioration to cills, masonry or bank structures than the preliminary survey showed. Specialist repair materials and details may then have to be agreed while the site is already under a closure.

Our approach

We record the exposed condition and each instructed repair by location, measuring against the original allowance and crediting work no longer needed.
