Barnstaple flue replacement project
We were awarded the contract for a flue replacement project for a main district heating plant room located in Barnstaple.
We engaged the services of a specialist contractor to assist with the design of a new steel column that would accommodate supporting 3 new stainless-steel flues.
Safety fencing and signage were erected, and a welfare unit was delivered to site prior to the project starting.
The 3 existing flues had to be taken down using a crane and once this had been carried out an investigation dig was required to confirm the dimensions and specifications of the existing concrete base. The existing concrete base failed the pull test therefore, we employed the services of Beveridge chartered structural engineers to design a new concrete base. Once the design was completed the existing base was dismantled and removed. The new concrete base was 4 meters square and due to the clearances required from the plant room we were required to excavate a larger area.
Prior to the excavation the area was scanned which highlighted a mains high voltage cable being in the way. Cable was disconnected at each end and the area was then rescanned. The excavation took place, and the cable was rerouted to allow for the correct size concrete base to be poured. Once the concrete base had fully cured the new steel column and flues were installed using 2 cranes to upright the column and then position into place.
The 3 flues were connected to the back of the Hoval boilers complete with condense drain points and stainless-steel pipework The plant room was renovated, and the boilers were fully stripped, cleaned, and serviced. The control panel was completely overhauled, and all redundant cables / components were removed. The Weishaupt burners had new electrodes and leads fitted and were then recommissioned.
The site was cleared and handed back to the client within 12 weeks.
