The project consisted of the construction of twenty-five individual cells within five structures for the storage and maturation of whisky products. Four of the structures were new builds and the fifth was the reconfiguration, upgrade and refurbishment of an existing unit within the site.
Ground quality was poor and the entire footprint of the site was subject to a ground remediation exercise during which over 54,000 m3 of top and sub-soils were excavated,
modified via lime and cement stabilisation techniques and replaced to form a structural capping allowing the foundations of the structures to proceed. The area was then capped with 26,000 tonnes of locally quarried stone product. Over 41 km of precast concrete piles were then installed below the structures to support the required floor loadings. Works then continued with the installation of over six thousand individual pad foundations, pile caps and ground beams.
Structural steelwork commenced in October that year and concluded in Feb 2013, during which time over 24,000
individual pieces of steelwork weighing more than 1,100 tonnes were erected and connected. After that, more than 13 acres of roof and wall cladding was installed to the
envelopes of the structures.
Over 180,000 individual concrete blocks were laid to complete the separating walls. Each of the 24 walls at approximately 800 m2 took an average one week to construct. 20,000 further concrete blocks and 95,500 facing bricks formed the perimeter walls and valve rooms.
Once protected, works commenced on the installation of approximately 12 acres of floor slabs containing 20,000 m3 concrete and nearly 1,500 tonnes of mesh reinforcement. To maximise the panel sizes and reduce the risk of differential settlement, a proprietary joint forming detail was developed and this, in line with specific concrete mix designs, allowed daily pours of around 180 m3 concrete to individual panels, which is nearly six times the size of normal.
