5 FOREWORD The General Specification for Civil Engineering Works lays down the quality of materials, the standards of workmanship, the testing methods and the acceptance criteria for civil engineering works undertaken for the Government of the Hong Kong Special Administrative Region. Where necessary, this General Specification should be supplemented by a particular specification

8 What is Engineering Survey? Engineering Surveying is an important disciplinary field that serves construction projects. to work as an engineering surveyor, providing geospatial information for construction projects. Engineering Surveying involves Project planning and design; Quality control of construction projects to ensure the projects progress according to their designs and given tolerances; and Monitoring the performance and health conditions of completed structures and facilities. Examples of construction projects that require professional services of engineering surveyors include projects in which buildings, highways, railways, tunnels for transport systems and utility systems, bridges and harbours are constructed.

Do you know the Organization in a Contract? Do you know the Role of survey team in a project? Do you know...

15 Surveyor General Specification for Civil Engineering Works (Section 1.09) (1) The Contractor shall employ on the Site a Surveyor for setting out the Works and for conducting slope and retaining wall record survey. (2) The Surveyor shall possess a Diploma/ Higher Certificate in Land Surveying or a Higher Diploma in Geomatics from a Hong Kong technical institute/ polytechnic or university; or an Associate Membership of the Hong Kong Institute of Surveyors in the Land Surveying Division; or equivalent qualification appropriate to the nature of the survey work required for the Contract, plus a minimum of 2 years of relevant experience in engineering surveying.
