SC22080 - A20 Coldharbour Roundabout and Hall Road Junction

Description

Kent County Council (the Council) is the largest local authority in England covering an area of 3,500 square kilometres. It has an annual expenditure of over £1bn on goods and services and a population of 1.6m. The Council provides a wide range of personal and strategic services on behalf of its residents, operating in partnership with the NHS Kent and Medway Clinical Commissioning Group, 12 district councils, and 289 parish/town councils. KCC consists of four directorates:\r \r • Adult Social Care and Health;\r • Children, Young People and Education;\r • Growth, Environment and Transport; and\r • Strategic and Corporate Services.\r \r This service is being commissioned on behalf of the Growth, Environment and Transport directorate.\r \r Scheme information\r Due to their close geographic proximity, it is intended to procure the A20 Coldharbour Roundabout and Hall Road Junction schemes together as a single package.\r \r The A20 Coldharbour Roundabout scheme requires the design and construction of a new larger roundabout to replace the existing signal-controlled roundabout junction on the A20 at Coldharbour Lane. The junction connects the A20 corridor to the Strategic Road Network at Junction 5 of the M20. The site is located 2km to the north-west of Maidstone, Kent on the A20 corridor between Allington and Aylesford.\r \r The existing crossroad junction between the A20, Hall Road and Mills Road, approximately 500m to the west of the Coldharbour Roundabout, is to be improved by the design and construction of a lozenge shaped roundabout to replace the existing traffic signal-controlled junction. The Hall Road junction forms the only point of access to the busy Quarry Wood Industrial Estate and South Aylesford Retail Park.\r \r The intent of both schemes is to support the level and distribution of development being proposed in the Tonbridge and Malling Borough Council and Maidstone Borough Council Local Plans, with new home allocations of around 843 dwellings per annum (dpa) and 883 dpa respectively. Furthermore, the schemes aim to ease congestion along the A20 corridor in Aylesford.\r \r Suppliers should note and be aware that there is the possibility that the A20 Hall Road Junction Improvement may be withdrawn from the Contract, prior to the ITT being issued. In this situation the ITT will be issued for the A20 Coldharbour Roundabout only\r \r The construction cost budget for the A20 Coldharbour Roundabout scheme is £3.5m and for the Hall Road Junction scheme it is £2.0m
