Technical Visit to: Contract No. K1499.B-18C - Slope Improvement Works along EAL Phase 5B

This project mainly comprises 3 slopes which located at Tai Po Market Station (D21.2 & D21.4) and Hong Lok Yuen (D23.8). For the slope identification, U stand for up-track meaning trains from Hung Hom direction going to Lo Wu direction, D stand for down-track, trains from Lo Wu direction going to Hung Hom direction.

The scope of works of this contract includes (a) Design and construction of hoarding, temporary protective fence, Working platforms and other Temporary Works for the Execution of the Works; (b) Carry out slope stabilization works, including installation of soil nails, rock slope stripping, mapping and stabilization works, slope trimming and backfilling, thickening of retaining wall structures and replacement of existing soil; (c) Provision of slope surface protection including shotcreting and hydroseeding; (d) Provision of surface drainage system, maintenance accesses, handrailing, security fencing and associated works; (e) Landscape works including planting and establishment works, and (f) Ground investigation works, instrumentation and monitoring.

In this visit, participants will gather at the site and a presentation on the works and challenges of the project will be given, followed by a site visit.

Cathodic Protection for Steel Reinforced Concrete Structures

The goal of this presentation is to provide enough understanding that you can recognize where corrosion is a concern and what your options are for managing it. Agenda: • Why CP is valuable to engineers, owners, and operators • Electrochemistry of corrosion: by understanding the process, you will realize the solutions • Factors affecting corrosion rates; aerobic vs anaerobic corrosion • The three ways to prevent corrosion • A little bit of history • Hong Kong environment; geotechnical applications • CP system materials • Protection criteria; standards • When to choose CP (and when not); choosing among CP system types • O&M • Value engineering • Q&A: Please feel free to bring real-world situations, geotechnical or otherwise

Advances in Shallow Seismic Investigation for Managing Ground Risk

Complementing traditional approaches to site characterisation, recent developments in near-surface seismic investigation techniques have led to better representation of ground structure and in-situ geotechnical properties, improving the likelihood of avoiding unforeseen ground conditions for infrastructure development. The civil engineering sector has sometimes had a somewhat jaundiced view of geophysics, but a properly designed, executed and communicated (and critically, early) geophysical screening strategy can help not only to optimise subsequent intrusive campaigns but to populate what can represent large information gaps (uncertainty) in the Ground Model space between points of control such as boreholes and probings and their associated localised tests. For existing and future infrastructure developments, looking ahead, the evolution of legislation relating to seismic site assessment and site vulnerability for dense urban areas such as Hong Kong necessitates an awareness of the art of the possible for geophysical investigation. We review six seismic methods where recent advances in data acquisition technology and/or processing offers an opportunity for improved early screening for infrastructure development and / or seismic site assessment, and benefits in terms of better risk evaluation and timely decision-making.

Technical Visit to the Netherlands - Study of Global Practices on Land Reclamation, Coastal Resilience and Spatial Urban Design

The HKIE Geotechnical Division is organising a technical visit to the Netherlands between 25 and 31 August 2019. The visit is aimed at enriching Hong Kong engineers’ knowledge on global practices on land reclamation, including coastal flood protection and ecosystem restoration, as well as spatial planning concepts in urban design including smart use of underground space. To meet the challenges faced by Hong Kong, it is a right timing for us to tap into other countries’ experience and expertise. The Netherlands is definitely a role model for us to learn, in particular regarding the strategy and approaches adopted in land reclamation, coastal resilience and city development.

Technical Visit to Contract No. NE/2016/05 - Development of Anderson Road Quarry Site - Pedestrian Connectivity Facilities Works Phase 2A

The works mainly include a) road improvement works at junction of Clear Water Bay Road and On Sau Road, and at New Clear Water Bay Road near Shun Lee Tsuen Road, b) construction a vehicular flyover from Lin Tak Road to Sau Mau ping road and provision of laybys at Lin Tak Road, c) construction of pedestrian connectivity facilities, including footbridges, lift towers and escalators in Kwun Tong district, d) provision of a public toilet for the proposed bus-to-bus interchange at Tseung Kwan O Tunnel Toll Plaza, and e) associated noise barriers and enclosures, slope works and landscaping works.

In this visit, participants will gather at the site and a presentation on the works and challenges of the project will be given, followed by a site visit.
