The project involves the removal and replacement of two existing chemical store extract ventilation systems, including fans, ducting, louvres/grilles, and electrical connections for the main and learner pool store. Works include installation of new high-pressure centrifugal fans, 250mm PVC ducting, fan speed controllers, mains power supplies, and replacement of corroded mesh screens on door louvres with non-corrosive material. The completed system will be tested, balanced, and commissioned to ensure proper operation. All work areas will be cleaned, cleared of debris, and left neat and tidy upon completion
