DAWSON-WAM’s primary business is Civil Engineering Contracting working on Water industry framework projects for Sewer Networks, Trunk Mains, WwTW and WTW with associated pipelines. Our IWWF framework participation, for Northern Ireland Water, has been 8 years in duration.

Over the last 12 years we formed Joint Ventures undertaking Design and Build projects for WwTWs, WTWs, sewers, trunk mains and water mains for NI Water. We have delivered:

Integrated Waste Water Framework: We are presently on the IWWF for NI Water.

Culmore WwTW: A £17m project which included extensive insitu concrete structures

Castor Bay to Dungannon STM:  A 52km £14m trunk main which included a 1km HDD 710mm OD twin pipe crossing of the Rivers Bann and Crusher, a canal and main railway line.

Belfast Sewers: We have recently completed Belfast Sewers Framework for NI Water which involved substantial amounts of pipelines with ancillaries, deep sewers, CSOs and a variety of pipeline rehabilitation techniques all in Belfast City centre.

Omega PPP: We were also construction partners to Laing O’Rourke/Thames JV (latterly L’OR/Veolia JV) for delivery of the £120M Omega PPP to NI Water. As part of our participation in the delivery of Omega PPP we constructed extensive large diameter pumping mains.

Specialist Piling Division: Through our specialist piling division we deliver sheet piling, steel support piling, bored insitu RC bearing piles, hard to hard secant piling, contiguous piling, temporary bridges and complete basement packages. We offer D&B with consulting engineering partners but also individually using our in-house design and CAD capabilities.
