Project Summary
Coffey delivered this contract for Louth County Council to upgrade the existing wastewater treatment works from a capacity of PE 68,000 to PE 101,000.
Project Description
Coffey acted as Main Contractor and Economic Operator for all civil engineering works associated with the plant upgrade and served as Principal Contractor for the site. The works involved the construction of new treatment tanks, pumping infrastructure, interconnecting pipework, and associated site development. The project design was provided by the client.
Scope of Works
The works included:
- Construction of a reinforced concrete primary settlement tank.
- Construction of two reinforced concrete aeration tanks.
- Construction of a reinforced concrete final settlement tank.
- Construction of a reinforced concrete pumping station.
- Installation of interconnecting pipework.
- Associated civil engineering and site works.
Technical Highlights
- Works carried out on a constrained, multi-level site with excavations up to 8 metres deep.
- Several tanks constructed fully underground adjacent to existing structures.
- Continuous operation of the existing treatment plant during construction.
- Coordination of multiple contractors on-site through regular progress and planning meetings.
Added Value
- Relocation of a tank to avoid undermining a retaining wall, saving the client additional costs.
- Introduction of trial trenching in advance of excavation to identify unrecorded services.
- Minimised delays by adjusting works to avoid unnecessary service diversions.
Environmental, Safety or Community Measures
- Careful planning to minimise disruption to local communities.
- Ensured the existing wastewater treatment plant remained operational throughout construction.
- Effective coordination of works reduced potential environmental impacts and safeguarded continuity of service.
