Read the full judgment text of HCCT 49/2002 on BabelCite. This 高等法院原訟法庭 judgment was delivered on 13 December 2006 before The Honourable Mr Justice Burrell.
Construction Law — Variation claims — Design and build lump sum subcontract — Interpretation of contract terms and bills of quantities — Whether additional works constitute variations — Expertise and evidence on quantification — Assessment of profit mark-up — Contra-charge claims — Allocation of responsibility for remedial works and alternative design measures — Delay claims — Onus on proving causation and loss — Interest awarded from date agreed — Costs orders. The dispute arose between Sunley Engineering & Construction Co. Ltd. (plaintiff, piling subcontractor) and Ngo Kee Construction Company Ltd. (defendant, main contractor) on a residential development project. The High Court analyzed entitlement to various disputed variation claims under a design and build lump sum subcontract, including extra excavation carting, additional coring and loading tests, site investigations, design works, and additional pile quantities. The court adopted a reasoned approach to assess quantum, including adopting a 20.5% mark-up split between opposing experts’ estimates. The court rejected Ngo Kee’s counterclaims including contra charges for rockfill plug provision, noting these were not in subcontract scope according to contractual documents and PNAP 227 did not bind the subcontractor. The major delay counterclaim by Ngo Kee was dismissed due to failure to prove actual delay to the main contract and causative loss. The court made a final award to Sunley including interest from June 2001 and directed costs in their favor without indemnity basis. This careful factual and legal analysis underscores principles in construction contract variation claims, expert evidence evaluation, and delay damages assessment.
