Paragraph 50 Ground works and surveysI1

The undertaker must provide written notice to TWUL as soon as reasonably practicable in the event they determine to alter the ground level more than 300mm within 5 metres laterally of the outside face of any apparatus. Upon receiving such notice, TWUL will determine if works under paragraphs 40(2) or 42(2) are necessary and the timescales in paragraphs 42(4) and 42(5) shall apply to such determination from the date of receipt of the notice.
