Challenge
Employed by Galliford Costain Atkins, on behalf of United Utilities, the scheme undertaken incorporated the electrical and instrumentation design and installation on the new water treatment plant at Liverpool WwTW. The new plant at Wellington Dock processes and treats sewage to the highest standards for approximately 600,000 people.
Picow were entrusted to complete this project under very demanding timescales. In order to achieve these timescales Picow and GCA engineers worked closely throughout the process to allow the design documents to be issued to site on a “just in time” basis time throughout the key stages of the installation. This included the electrical development of the overall BIM model (A new mandatory concept for the industry at the time of this project)
Solution
Our scope of works involved the full electrical installation including primary low voltage distribution, primary and secondary cable management systems, hardwired power and control cabling to instruments and control panels, Profibus DP & PA networks, fibre optic networks, general building services power and lighting, trace heating power and control systems and also fire and intruder alarm systems. The above installations incorporated hazardous area design, installation and inspections in accordance with the United Utilities / GCA DSEAR Risk Assessment.
Outcome
This project embraced the use of BIM technology, a relatively new concept within the water industry at the time. United Utilities invested early in the project for the generation of a 3D model for the new facility to enable integration of all the services in a virtual environment. Picow were responsible for the electrical element of the model, submitting our installation to be confederated within the main model. By embracing BIM technology clashes were identified prior to the construction phase eliminating installation problems between the various disciplines. Due to this approach the project was a complete success and the installation was completed well within the programme timescales.
