Doors to be fully watertight with all associated seals and gasketry supplied. Gates to be hinged on 1 side only with a watertight seal achieved up to the surrounding reinforced concrete course structure. Gates to have a corrosion protection system suitable for use in chlorinated swimming pool quality water. • Penstock gates: o Design, supply and installation of a number of penstock gates within the white-water rafting centre, Georges Dock, Dublin. 6 no. gates are required varying from 500x500mm to 1500x2500mm; wall mounted in both on-seat and off-seat locations. o Penstocks are to be of a stainless steel/ HDPE construction with EPDM seals. All penstocks are to be supplied with their own motorised actuator drive. 1 no. of these penstocks is to be a modulated rack and pinion system. Please see attached documentation.
