Paragraph 16 I1

If any permanent or temporary alterations or additions to Canal & River Trust property are reasonably necessary in consequence of the construction of a specified work or a protective work during construction, or during a period of 24 months after the completion, of that work in order to ensure the safety of Canal & River Trust property or the continued safe operation of the waterway, such alterations and additions may be carried out by Canal & River Trust.

If Canal & River Trust gives to the undertaker reasonable notice of its intention to carry out such alterations or additions (which must be specified in the notice), the undertaker must pay to Canal & River Trust the reasonable cost of those alterations or additions including, in respect of any such alterations and additions as are to be permanent, a capitalised sum representing the increase of the costs which may be expected to be reasonably incurred by Canal & River Trust in maintaining, working and, when necessary, renewing the alterations or additions.

The engineer must, in respect of the capitalised sums referred to in this paragraph and paragraph 15, provide such details of the formula by which those sums have been calculated as the undertaker may reasonably require.

If the cost of maintaining, working or renewing Canal & River Trust property is reduced in consequence of any such alterations or additions, a capitalised sum representing the saving must be set off against any sum payable by the undertaker to Canal & River Trust under this paragraph.
