West Medina Mills, Stag Lane, Newport, Isle of Wight

Client: South East England Development Agency (SEEDA)

Value: £2.6m

Contract: ICE 7th Edition

The existing reinforced concrete road was demolished and a new 1.2km adopted highway constructed in its place to provide access for a new Wind Turbine R&D facility on the Isle of Wight. Associated works included storm water drainage, a 3m wide cycleway along the full length of Stag Lane, a new car park for the Stag Inn Public House, tie-ins to residential and business properties and major earthworks.

 

The project scope was to provide an adoptable access highway road to a new wind turbine research & development facility located between East Cowes and Newport of the Isle of Wight. The project comprised the following elements:

  • Demolition of the existing 1.2km reinforced concrete road, site clearance, bulk earthworks
  • Construction of a new 6.75m wide, 1.2km long highways-adopted tarmac carriageway
  • Construction of a 3m wide, 1.2km long cycleway
  • Cconstruction of a 1.78m wide verge to the full length of Stag Lane
  • Tie-ins of new carriageway to residential and business properties
  • Installation of new traffic signals
  • Section 278 works
  • Storm water drainage and ducting works
  • Installation of new water, electric, gas mains to feed new R&D facility
  • Construction of a new car park to the Stag Inn
  • Construction of a new retaining wall to the Stag Inn and associated railings
  • Re-grading of an existing ditch
  • Removal of soft spots
  • Demolition of an existing sub-station.

This project was delivered in two distinct phases:

Phase 1 (Section 278 Works)

The reconstruction of the existing Stag Lane / Horsebridge Hill simple T junction into a traffic signalled controlled right turn junction which was carried out under a Section 278 Agreement.

Phase 2 (Section 38 & Section 228 Works)

The reconstruction of the existing 1.2km reinforced concrete road with a 6.75m wide industrial access road complete with verges, footpath, cycleway, drainage, new services, and various accommodation works. The road was constructed under a modified Section 38 Agreement with adoption under Section 228 of the Highways Act 1990.

Phase 2 works required sectional completion because the works coincided with the development of a large wind turbine R&D facility located at the eastern end of Stag Lane, the road was required to be kept fully operational for the duration of the works. The sectional works were carefully planned and executed with the key stakeholders being liaised with during both the planning and construction stages.

 

The waste generated by the project was recorded on our Site Waste Management Plan which forms part of our ISO 14001 accredited quality management system. The waste streams comprised woodchips; concrete; tarmac; topsoil; skips; and general muck away. Of these waste streams, 100% of the topsoil stripped was re-used as suitable soil for the soft landscaping works, and 100% of the woodchips, concrete, and tarmac was diverted from landfill and sent to an off-site recycling facility.

The topsoil and clay material stripped during the excavation works were reused on the site to form the raised profile cycleway constructed adjacent to the new road construction. The existing concrete road was crushed and re-used as a suitable sub-base material.

100% of the concrete which formed the existing retaining wall was diverted from landfill and sent to a recycling facility.

 

The site required access to be maintained to a larger development in progress at the eastern end of Stag Lane along with local businesses and residential properties. The works required phasing to enable construction to progress while simultaneously providing access to the stakeholders resident along the Stag Lane road re-construction.

To provide continued access along the length of the existing Stag Lane during construction Dyer & Butler maintained a system of constant road cleaning during the earthworks utilising a dumper with a road brush and wash attachment. The vehicle was in operation at all times during the earthworks.

The scope of the works increased by a significant amount as the project progressed including alterations to the storm water drainage and carriageway construction.

Dyer & Butler ensured a pro-active management style accommodated the changes and ensured they minimised impact on the programmes critical path.
