The £10m A585 Norcross Roundabout Scheme saw client, designer and contractors work effectively together under National Highways’ Asset Delivery (AD) style contracts, where collaboration and teamwork is the cornerstone of delivery. Carnell were principal contractor on the multidisciplinary scheme which included a number of Lot contractors from the AD Construction Works Framework (CWF).
The scale of the scheme can be seen in numbers:
- 1650m linear metres of drainage.
- 5000m of lighting and traffic signal ducting.
- 20,000 tonnes of material imported
- 50 traffic signal poles erected.
Collaboration and collective problem solving enabled several benefits: Design was brought forward by 5 months through ECI. Land procurement delays were mitigated through an alternative construction strategy, and delays from utilities companies were solved by re-sequencing the construction programmes.
During construction, value engineering continued and a number of efficiencies were identified and accepted by National Highways which saved in excess of £600k.
