Miles constructed 19,650 SF of food grade clean rooms for housing of production lines within an existing warehouse. Each of the 3 rooms ran a length of 262 feet and were varying heights ranging from 14’ to 20’. This required the installation of a new 12” slab over the top of the existing slab. The new slab contained trench drains that ran 220’ of the 260’ long rooms. Each room has a 3’ concrete stem wall that is integral to the slab and sealed with an acid resistant concrete sealer. Each production clean-room has its own dedicated environmental system to heat and cool the space independently of the shell building. This provides for a separate fresh air system that allows them to maintain the clean-room environment. All mechanical and lighting systems are fully controlled with a DDC system and are integrated into the users building controls.
