Client: Seymour Civil Engineering
Location: Land off Nether Lane, Ecclesfield, Sheffield

Working with the client and Yorkshire Water (YWS), the project involved the development of a new vehicle parking area to accommodate private cars, and YWS’s fleet of vans and maintenance vehicles.  The site included spaces for EV charging to meet YWS’s target for electric vehicle use.

The site is located adjacent to the B6087 in Sheffield to provide parking for the YWS depot at Ecclesfield..  The site also included overhead electrical cables and supports which influenced the layout of proposed site and is close to an existing watercourse and Network Rail infrastructure.

Lynas Engineers acted as the Principal Designer for the Design and Build contract working closely with Seymour Civil Engineering to develop the tender design; develop the detailed design; and advise during the construction phase.

The scheme included the design of a bituminous car park; a new junction onto the B6087 under a S278 agreement; earthworks design to provide a new formation level; site security; lighting and infrastructure for electric vehicle charging. The drainage network was designed to attenuate the surface water from the new parking using an underground tank and flow controls to restrict flow into the adjacent watercourse.  Pollution control measures were also incorporated with the inclusion of an oil separator.

Challenges:
Designing within a constrained site with difficult topography and limited site access. Providing spaces and access for varying vehicle types and sizes.

Successes:
Providing a full package of drawings which were updated live throughout the construction phase. Positive feedback received from Sheffield City Council in regard to the Section 278 approval process.

The site is adjacent to a watercourse which required protection from pollution during the construction phase and whilst in use. We used our Preferred Partners network for specialist design of lighting and EV charging.
