The Institute of Quarrying Hong Kong Branch, with other Professional Institutions, was invited by the Hong Kong Government to be a member of the Working Group on the redrafting of the ‘Cavern Geoguide’, which was published January 2018.

First published in 1992, the Geoguide sets out to provide guidelines to planners and designers engaged in cavern projects. To date a number of caverns have been built, these include stations for the Underground system in Hong Kong (known as the MTR), a sewage treatment works, a reservoir, refuse transfer station and an explosives magazine. The intention now is to develop this further using recent experience from elsewhere in the world but primarily from the Nordic Countries of Europe. Ove Arup and Partners have been consultants to the Government on this project.

The Study has been wide ranging and included references to working practices and experiences from underground quarrying for dimension stone. Making full use of the rock being excavated as a resource to be used as a construction material was one key intention of the Geoguide.

The local branch provided input into quarry practices and ways to ensure that the excavated rock could readily be crushed and screened for use in concrete and asphalt in the most effective way for contractors, aggregate producers and end users.

An online copy of the Geoguide can be accessed here.
