We were engaged as the Contractor’s Designer to undertake the building designs for an Administrative and Workshop Building, 3 Nos. Fine Screen Buildings, Switchgear and Transformer Rooms, seawater pumping stations, chambers and the auxiliary structures for the upgrading of DSD treatment works in Island South Districts. Our service also included supervision of geotechnical and foundation works. For instance, in our design of Cyberport Pumping Station, there were numerous single-storey buildings with minimum 6m above ground. Like DC/2009/23, we have taken loadings consideration of drainage facilities pumping equipment, generator, etc to design the concrete structures which was close to shoreline and thus corrosion protection to reinforcement, settlement of the building, uplift consideration and vibration effect to adjacent existing structures were our prime concerns. Furthermore, our design has included curtain wall, finishing, green roofing, balustrade, etc design. During construction, we have also designed the ELS for the construction of the pumping stations and conducted periodic site inspection and checking of monitoring works of the as-constructed building structures.
