PROJECT PROFILE
DERG WATER TREATMENT WORKS
the data was used to assist the design/ contractor team to deliver the best solution for this location.” Having selected clarification using liquid- activated carbon as the best solution, LBCE worked collaboratively with the client and project manager to deliver the infrastructure on time and to budget. The project included construction of a new building matching in with the existing structure, and a cofferdam 5m below ground, with 1700m 3 of concrete, 214T of reinforcement steel and 96T of structural steel used during construction. “The impressive site set-up was established, maintained and managed perfectly and the project required extensive concrete pours to create large tanks and structures and, consequently, to ensure working-at-height safety when constructing around these tanks and structures using bespoke platforms,” said Jemma. “Under our ISO14001 accreditation procedures, we meticulously monitored our environmental performance, proactively meeting stringent waste
targets. Our water, fuel, electricity use, and subsequent carbon emissions were all strictly monitored and reduced. “The works area was situated adjacent to the existing WTWs. Therefore, extreme care and precaution was taken to ensure minimal disruption to this essential service throughout the works and comprehensive planning to ensure the switchover was completed with no interruption to public water supply.” Mitigation measures had to be introduced to address the onsite presence of badgers and invasive species Himalayan Balsam. “Our team worked tirelessly to deliver exceptional ISO9001 build quality while adapting to changing requirements, for example dosing and storage of treatment chemicals were adjusted to suit revised client requirements,” said Jemma. “Innovative methods for supporting wall reinforcement as part of the temporary works were implemented and prefabrication of formwork and reinforcement which improved safety and programme.”
LBCE has delivered a 30% increase in capacity, reduced wash water consumption improvement in turbidity figures to 0.5 NTU and extended runtime for primary filters. “This project is special to LBCE as it is a few miles from our head office and brought a large-scale infrastructure improvement to our local area, in addition to many jobs provided for our staff and local supply chain throughout the construction period,” said Jemma. “It was a mixture of heavy civil engineering activities and building, which is where we really provide excellence with a multidisciplinary team.” Client: Northern Ireland Water Main Contractor: Lowry Building & Civil Engineering (as part of DLG Joint Venture) NEC Project Manager: RPS Consulting UK & Ireland PROJECT TEAM...
