Running parallel with this we are working with the numerous stakeholders and statutory bodies in order to ensure all aspects of the delivery work is discussed and permits and permissions are in place – what does that mean in the real world? Lots of paperwork!
The project sensibly breaks down into three components:
- A source of heat (the sea)
- Compressor units (to raise the temperature)
- A sink to which the heat is delivered (the mansion house)
In order to get the heat harvested from the sea all the way to the mansion we have to place intake and outfall pipes in the sea; these lead into a pumphouse on the foreshore where a heat exchanger will harvest the heat; closed loop pipes will then transfer this heat up the hill to the heat pumps located in the stables; finally heat main will carry this heat to the mansion itself. Sounds simple.
Now we hit the paperwork!
- Planning permission is required for the pumphouse building and the pipework trenching work from the foreshore to the stables.
- Listed building consent is required as we are putting the pipework into the Grade 2* listed stables.
- Archaeological assessment and watching brief are required as we are working within a historic landscape.
- Tree survey assessments are required along the route of the pipework.
- Visual impact photomontage work is required for the pumphouse building on the foreshore.
- Cadw consultation is required as we are working within the historic setting.
- The Crown Estate have been consulted in order to obtain permit to work on the foreshore itself. Additionally an easement for the intake and outfall pipes to cross the foreshore into the sea is required.
- Natural resources Wales (Environment Agency and Countryside Council for Wales previously) have been consulted and a flood consequence assessment is required for the pumphouse.
- Dive surveys and ecological assessments have been completed for the area below low mean tide.
- Marine licence construction permit is required to work within the sea itself
All of these elements are time consuming, but will ensure that the construction phase runs smoothly.
