Formerly the site of the old Edinburgh tram depot and the Shrubhill masonic club, the area is now under re-development. The new works are a modern complex comprising of a leisure block and 5 blocks of flats. All heating and water services are from a central plant room feeding each building.
The heating is supplied via a district heating system with a central boilerhouse feeding all the buildings. My job is to fit the brackets and run 8 pipes from the boilerhouse, through the basement car park and up 4 risers. The 8 pipes are a mixture of 65mm Victaulic heating mains, 50mm screwed steel heating mains and 54mm crimped copper water services pipework. These will be for the current phase of the project which is 2 blocks of flats with 6 floors to a block. After this I'll fit the pumps in the boilerhouse and tie the mains into the pumps.
The site has re-opened for construction after almost 3 months since lock-down began and work can now progress. I am now employed by BPS and currently fitting pipework in the car park, risers, flats and communal flats landings (4 flats on a landing) over 6 levels.
The flats are fitted, the risers are done, the car park mains are almost complete. I'm now fitting 5 sets of pumps and tying the mains into the pumps. Four of the pumps are in 50mm screwed steel and one in 65mm Victaulic (In progress).
All flats are fed from the riser. The riser pipework consists of a 50mm screwed steel heating flow and return with 40mm branches to the floors, a 54mm copper mains cold water to the first and second floors with another 54mm copper boosted cold water to all other levels.
We're now on block D. This is the final block of flats for the project and is a listed building. I'm now working self employed so who can tell how much longer I'll be there. So far I've been fitting
- The last of the 2" coiled Uponor connections (That stuff was a complete nightmare to work with)
- The 2" screwed mains to feed the block
- 28mm & 22mm Pressfit copper pipe runs in the flats
As I'm the only time served heating engineer on the job I'd expect to be there until the tasks 1 and 2 below are done then it's get rid of the agency guy time and off to pastures new. We'll see!
- Fit the HIU's (as shown in the image)
- Fit the mains riser pipework
- Tie the corridor mains into the riser pipework on each floor
- Fit the last set of pumps in the boilerhouse
