The Stanway site is located approximately 4.3 miles west of Colchester
city centre on the edge of Stanway and less than one mile south of
the A12. The total site area extends across approximately 60 Ha,
bounded by existing housing to the east and the Tollgate shopping
centre immediately to the north. Land to the south has recently been
developed into residential use (Lakelands Phase 1).

The Western Relief Road at Stanway will enable the construction of a
new housing development on the site of a former sand and gravel
extraction site. In order to facilitate the Lakelands Phase 2
development, a significant earthworks re-contouring exercise has
been undertaken involving approximately 500,000cu.m of material
excavation and deposition together with the construction of a 2km
long relief road. The existing Phase 1 development comprises
approximately 300 dwellings and Phase 2 will comprise up to 500
dwellings.

BWB are carrying out infrastructure design, earthworks design, site
supervision and CDM Co-ordinator services on behalf of O&H
Properties Ltd.

Key Challenges

The significant earthworks movements needed careful monitoring to see that the required compaction in deep fill areas was achieved. The existing alignment of Church Lane, which crossed the route of the relief road, needed to be formally Stopped Up and a new bridge provided over the relief road for a re-aligned Church Lane.

BWB provided engineering support throughout the duration of the works to see that the earthworks and highway works were carried out in accordance with appropriate standards and were carried out safely. The earthworks were designed to achieve a cut/fill balance in order to minimise the requirement for import/export of materials. Existing materials were re-used wherever possible by crushing, screening and processing to create primary and secondary aggregates for road and drainage construction thus helping to minimise the environmental impact of the project.
