Scott Watson, Senior Project Manager

Drainline Construction have worked with J. Coffey Construction on our Crossrail Project at Plumstead on numerous occasions. The scope of works has been sewer connections, pipe laying, temporary works, deep excavations and Thames Water connections. On all works I have found them to be on time and extremely helpful with offering solutions technical queries that arise during the works. The operatives are experienced and efficient at the works they undertake. 

I would have no hesitation in using them again in the future.
