Project Summary
Coffey was appointed for the construction, testing and commissioning of a new 11.2 km pipeline to main out both Kaim and Dougliehill Water Treatment Works from Greenock Water Treatment Works. The works were carried out across a combination of agricultural and urban areas, including significant sections through rocky ground.
Project Description
The project comprised the installation of 11.2 km of new pipeline infrastructure, with 9 km laid in agricultural land and 2.2 km laid within the A761 Kilmacolm Road in Port Glasgow, including town sections. Excavation in rocky ground presented challenges, and careful traffic management was required throughout. Close liaison with landowners and coordination with road users ensured that works were delivered with minimal disruption.
Scope of Works
The works included:
- 11.3 km of pipelines.
- 5.1 km of 100 mm electrical duct.
- Associated pipework, valves, tees, hydrants and civil works.
- Pipeline installation across both rural and urban areas.
- Complex traffic management for single carriageway roads, ranging from 2-way to 4-way setups.
- Work sections up to 300 m long, often with two pipelaying gangs working simultaneously with traffic management set-ups approximately 1 km apart.
Technical Highlights
- Installation of a large-diameter pipeline system over 11 km in challenging ground conditions.
- Coordination of dual pipelaying operations within confined traffic management arrangements.
- Delivery of both PE and ductile iron pipelines to meet operational requirements.
Added Value
- Careful planning and traffic management minimised disruption in urban areas.
- Liaison with local landowners supported smooth progress through agricultural land.
- Efficient programming allowed simultaneous pipelaying operations to accelerate delivery.
Environmental, Safety or Community Measures
- Traffic management measures reduced disruption to the local community.
- Close communication with landowners ensured agricultural activities were respected.
- Safe working methods adopted in both urban and rural environments.
