It will connect the West Kowloon Highway at Yau Ma Tei Interchange with the road network at Kowloon Bay and the future Trunk Road T2 at KTD which will connect to the future Tseung Kwan O – Lam Tin Tunnel (TKO- LTT). 1.1.2 On 30 June 2011, Highways Department (HyD) of the Government of the Hong Kong Special Administrative Region appointed the Arup – Mott MacDonald Joint Venture (AMMJV) under Agreement No. CE43/2010(HY) to provide consultancy services in respect of Central Kowloon Route – Design and Construction (this hereafter called CKR project). 1.1.3 In I&PD consultancy, a C&DMMP was prepared and submitted by Mott Connell- Meinhardt – Hyder Joint Venture in Dec 2008. 1.1.4 After the design review of CKR under current consultancy, the land use, road layout and extent, and the construction programme have been revised from I&PD stage. The alignment has been revised and fine tuned in accordance with the review findings. The review will be completed in early 2012. 1.1.5 In Dec 2011, the Consultants proceed with the advancement of EIA study in order to provide necessary information for the subsequent public consultation in May 2012. The commencement of gazette process is scheduled in August 2012. According to the brief, the CKR construction contract commencement is scheduled in early 2015 while the CKR commissioning is scheduled in year 2020. 1.2 Scope of Project Works 1.2.1 Based on the latest design development, the Project comprises of the followings:- (a) A dual 3-lane east-west trunk road about 4.7km long with about 3.9km in tunnel connecting West Kowloon with the proposed KTD; (b) Connection with Yau Ma Tei Interchange of the West Kowloon Highway and associated road network in West Kowloon; (c) Connection to future Trunk Road T2 and associated road network in Kowloon Bay and KTD; 217722-REP-023-01 | Issue 4 | August 2012 217722-REP-023-01 REV 4.RTF Page 1 Highways Department Agreement No. CE 43/2010 (HY) Central Kowloon Route - Design and Construction Updated Construction and Demolition Material Management Plan (d) A landscaped deck at the west portal and the structure of landscaped decks above the depressed road at east end; (e) Demolition and/or reprovisioning of Government and other facilities affected by CKR; (f) Reprovisioning of the section of Gascoigne Road Flyover affected by CKR; (g) Conservation of the Yau Ma Tei Police Station; (h) Enhancement works at Yau Ma Tei and Ma Tau Kok; (i) Tunnel ventilation system and air purification system, and associated ventilation buildings, adits and shafts; (j) Administration buildings, tunnel management system and operator facilities for the management and operation of the tunnel; (k) Traffic Control and Surveillance System (TCSS) for CKR, and associated interface with TCSS for other Route 6 projects and CBL, and control centres; (l) Associated environmental, geotechnical, marine, landscape, utility, drainage, traffic engineering, fire services, electrical and mechanical works, and road works and modification works; and (m) All other works associated with the construction or future operation of CKR. 217722-REP-023-01 | Issue 4 | August 2012 217722-REP-023-01 REV 4.RTF Page 2 Highways Department Agreement No. CE 43/2010 (HY) Central Kowloon Route - Design and Construction Updated Construction and Demolition Material Management Plan 2 Purpose and Objective of this Construction & Demolition Material Management Plan (C&DMMP) 2.1 Purpose and Objective of the C&DMMP 2.1.1 This updated Construction & Demolition Materials Management Plan (C&DMMP) is prepared with reference to the guidelines and requirements given in Chapter 4 section 4.1.3 of Project Administravtion Handbook (PAH) – ‘Management of Construction and Demolition Materials including rock’ and HyD Technical circular No.7/2003. The main purposes of this update reports are to: • draw up a Construction and Demolition Material Management Plan (C&DMMP) at an early design stage to minimize C&D material generation and encourage proper management of such material. • vetting of the C&DMMP prior to upgrading of the project to Category A in the Public Works Programme; • provide the future contractor with information from the C&DMMP in order to facilitate him in the preparation of the Waste Management Plan (WMP) and to minimize C&D material generation during construction. • enable classification and estimation the quantities of C&D materials generated and their time of generation and disposal method; • recommend ways to minimise the generation and to maximise the benefical reuse of inert C&D materials; • investigate the arrangement for the delivery of excavated C&D materials and review possible barging point. • enable the Vetting Committee to scrutinize and endorse the C&DMMP and monitoring of its implementation; • provide the information for management of C&D materials in the EIA report for this “Designated Project” under the EIA Ordinance. 2.1.2 As required by the Chapter 4 section 4.1.3 of PAH, a C&DMMP at the feasibility study or preliminary design stage for each project which generates more than 50,000m 3 of C&D material including rock or that requiring imported fill in excess of 50,000m 3 shall be prepared. The CKR project would fall within this category. 2.1.3 The objective of this C&DMMP is to present the estimation of C&D materials. Another objective is to ensure that options are considered in 217722-REP-023-01 | Issue 4 | August 2012 217722-REP-023-01 REV 4.RTF Page 3 Highways Department Agreement No. CE 43/2010 (HY) Central Kowloon Route - Design and Construction Updated Construction and Demolition Material Management Plan the planning and design of the development in order to reduce the generation of C&D material and encourage the reuse of the C&D material generated. The C&DMMP also provides basis for the monitoring and management of the C&D material and imported material throughout the construction period of the Project. The main principle for the management and planning of C&D material includes: • reduce the generation of C&D materials at source; • maximise the reuse of C&D materials; and • maximise the recycling of C&D materials. 2.1.4 This C&DMMP covers the sections of the CKR as shown in Figures CKR/F/01/0001 in Appendix A. This report covers only the CKR C&D materials which excluding the marine sediment, contaminated materials.
