Highways civil engineering projects

We deliver high quality civil engineering projects across the UK utilising a wealth of knowledge and experience gained nationally and internationally. We work closely with our clients to identify each scheme’s individual requirements with regard to programming, procurement, project delivery and public liaison.

The works we carry out include footway and carriageway construction, paving, groundworks, earthworks, drainage improvements including installation and design of Sustainable Urban Drainage Systems (SUD), street furniture and signage and hard and soft landscaping.

Defence estate projects

Some of works are for defence clients such as the Ministry of Defence, DIO, Qinetiq, Interserve, Aspire and BAE Systems. These projects involve working in high security areas and we understand the sensitive nature and implications of these schemes’ locations.

Previous works for these clients have included upgrading the entrance to Trafalgar Gate at the Portsmouth Naval Base to improve security, heavy-duty crane slab construction, airfield construction and maintenance, resurfacing of roads across a number of defences’ bases, rejuvenation of existing roads, car park construction and term maintenance contracts providing a wide variety of civil engineering works.

As a highly accredited NRSWA (New Roads and Street Works Act) contractor we work collaboratively to execute the requirements of Section 278 and Section 38 works within urban and rural environments.

We work with all named parties to the S278 agreements at an early stage to offer all stakeholders a flexible approach to programming works to suit their requirements and timescales. These works involve liaising with various parties including the client, other contractors, statutory undertakers and affected stakeholders.
