This is a large scale roadwork project forming a major part of the overall Tsuen Kwan O – Lam Tin Tunnel project in Hong Kong. During the tender, Vector was requested to carry our detailed quantity checks for roadworks, drainage, sewerage, and waterworks, structures & slopeworks, retaining walls & slopeworks, underpass, troughs, bridge abutments, transformer room, landscape softworks & irrigation. Vector carried out this checking via a combination of 5D BIM modeling and traditional QS techniques.
