Critical milestones have been met on the construction of a new £14M state of the art Combined Heat & Power (CHP) biomass plant at Troon for Glennon Brothers.

After a busy 6 months the 3b construction site team are nearing completion of the new CHP plant; despite the extremely onerous programme the key dates were met or bettered and the works have been delivered under budget. The plant, which will process sawmill cutoffs into useable, clean energy, will deliver 10.9 MWth and 2.33 MWel energy.

In addition to the CHP plant other structures have been constructed which include walking floors, belt dryers, wood chip silos, a progressive kiln, district heating pipework and ancillary structures such as substation buildings, loading gantry and chip loading building.

The construction of this new state of the art CHP plant provides the final link in transforming Glennon Brothers, Troon into a fully integrated site. Logs are delivered from the coasts and islands of Scotland by boat, to be processed in the sawmill. Some of this finished timber will then cross the road to their engineered timber facility, Alexanders Timber Design (ATD), to be incorporated into quality timber frame homes. The CHP plant will produce sufficient electrical power to power the whole plant and export up to 2.5MW of power to the National Grid. Additionally the hot water will be pumped across the road through the 1.2km long district heating pipes to provide heat for the timber drying kilns.

3b construction, acting as Principal Contractor, were able to achieve the demanding 6 month contract programme, for power to grid, as a result of their integrated approach to construction with over 90% of the construction works being delivered by their in house labour and plant which included earthworks, groundworks, reinforced concrete, structural steel framed buildings, building cladding works, M & E works and internal fit out from joinery to painting. Good collaboration between client, 3b construction, plant installation contractor, designer, QS and architect enabled a positive site team to be created which all worked together towards the shared goal.
