Revision Date: January 2021SECTION 11.1INTRODUCTIONGeneral1.1.1The Development Bureau (“DEVB”) aims to deliver quality public worksprojects in a safe, timely and cost-effective manner. While maintaining the openness, fairnessand competitiveness of the tendering process, the procurement system as a whole should beefficient and effective to facilitate selection of suitable and capable contractors in a smoothmanner to meet the fast pace of public works programme. A suite of administrative andregulatory framework covering the entire procurement process has been developed. Thepolicy objectives and procedures are detailed in handbooks, circulars and circular memorandaavailable at the websites of DEVB and works departments.1.1.2In view of the vast volume of public works contracts to be delivered, DEVB hasestablished the List of Approved Contractors for Public Works (the “List”) and the List ofApproved Suppliers of Materials and Specialist Contractors for Public Works (the “SpecialistList”) to achieve procurement efficacy and facilitate quality assurance. Public works tendersare usually invited from contractors on the List and/or the Specialist List.1.1.3By nature of works, the List comprises five categories: Buildings, Port Works,Roads and Drainage, Site Formation, and Waterworks; and the Specialist List comprises some50 categories as at the date of the current version of the Contractor Management Handbook(the “Handbook”).1.1.4To support the procurement of public works contracts, DEVB, with the assistanceof the Managing Departments, administers the List and the Specialist List through thefollowing processes:(a)assessing a contractor’s technical and financial capabilities at the time ofapplication for admission to the List / Specialist List;(b)further financial vetting before recommending the award of a contract to acontractor;(c)monitoring the contractor’s performance and, as appropriate, financialcapabilities periodically;1–1

Revision Date: January 2021(d)taking regulating actions against the contractor as necessary;(e)reviewing the contractor’s technical and/or financial capabilities when there areany significant changes to the contractor’s company which may affect thecontractor’s listing status; and(f)confirming the suitability of retaining the contractor on the List / Specialist Liston a triennial basis.1.1.5The guidelines and procedures pertaining to administration and monitoring of theperformance of contractors and suppliers on the List and the Specialist List are consolidatedinto the Handbook. DEVB reserves the right to amend the provisions stipulated in theHandbook and any criteria pertaining to the administration of the List and the Specialist Listwithout prior consultation with contractors on the List and the Specialist List and any suchamendments will be published by DEVB in the appropriate manner.1.1.6By making an application for admission to the List and/or the Specialist List underany category, the contractor unconditionally accepts the provisions stipulated in the Handbookand any future amendments or additions thereto. Failure or refusal to observe the provisionsstipulated in the Handbook may lead to refusal of the application for admission to the Listand/or the Specialist List under the category being applied for, or removal from all categoriesof the List and/or the Specialist List in which the contractor is listed.1.1.7A contractor on the List and/or the Specialist List is required to submit updatedcompany information (including but not limited to updated partnership agreements ifapplicable) upon request of DEVB or the Managing Department for reviewing his listing statusas and when required. It is the duty of the contractor to immediately inform DEVB of anymaterial changes of his company which may affect his listing status.1.1.8A contractor on the List and/or the Specialist List shall be responsible for the goodbehaviour of his employees, agents and subcontractors in relation to any public works contractunder his control. The contractor shall advise his employees, agents or subcontractors thatthey are not allowed to offer or give any advantage or excessive entertainment to any of theGovernment employees or members of their families, or to solicit or accept any advantage orexcessive entertainment from other employees, agents or subcontractors in relation to the worksunder any public works contract. The contractor may be subject to regulating actions as statedin Section 5 if the contractor, his employees, agents or subcontractors have committed anoffence under the Prevention of Bribery Ordinance (Cap. 201) in relation to any public works1–2
