Hatfield Business Park: Roehyde Junction Improvement
Scheme
Project Introduction
Scott Wilson was appointed to provide detailed highway and
infrastructure design to Arlington Development Management Ltd, a
developer, in January 2000. The construction cost was £8m.
Project Background
As part of the 363 Ha mixed use redevelopment of Hatfield
Aerodrome Arlington, was obligated to provide certain capacity
related improvements to the local strategic highway network. One
element of this work included a major improvement of the
grade-separated junction linking the A1(M) to the A414 and
the A1001known as Roehyde Junction (A1(M) Junction 3). The main
challenges of this project were the implications of undertaking
work in a traffic sensitive and highly constrained, environmentally
sensitive area of regional importance, and the large number
of stakeholders with a vested interest in the works.
Project Scope
Key services provided by Scott Wilson included:
Highway engineering, traffic signal and street lighting design,
geotechnical and structural engineering, environmental surveying
and reporting, hydrological modelling, holistic advice to the
Client on a number of issues including programming and technical
engineering issues, Statutory undertaker coordinator, value
engineering and Road Safety Audit.
Value Adding Project Achievements
In addition to the provision of an engineering consultancy
service, an innovative and flexible approach formed a core part of
the successful delivery of key objectives. Close liaison with the
Environment Agency and the Statutory Undertakers also produced a
number of innovative solutions to issues that either allowed the
scheme to be approved by the Highway Authority, offered a saving to
the Client, or improved buildability. This included the adoption of
a special face detail to a retaining structure to promote
vegetation growth and the alteration to a design of a structure to
avoid the need for a £250,000 diversion to a Thames Water foul
water main.
