 site safety supervision;
 appointment of Technically Competent Person to supervise
demolition works and operator of powered mechanical plant or
equipment; and
 certification of completion of works.
PNAP 71 [ 4 ] sets out the procedures to be followed by Authorised
Persons (AP) and Registered Structural Engineers (RSE) in meeting
these requirements. Some points for practical application are also
clarified.
Chemical wastes are liquid, semi-solid and solid wastes which are
hazardous in nature or constitute a risk of pollution to the environment.
Chemical waste is defined by reference to a list of chemicals which forms
Schedule 1 of the Waste Disposal (Chemical Waste) (General)
Regulation. The Regulation provides for the definition of chemical waste,
the registration of persons producing chemical waste and the control of
the possession, storage, collection, transport and disposal of chemical
waste.
In 2006, the Government introduced the construction waste disposal
charging scheme and the quantity of construction waste disposed of at
landfills decreased from 6,560 tonnes per day in 2005 to 2,910 tonnes
per day in 2007. This figure fluctuates depending on the economics
situation and the number of construction projects underway.
In May 2003, ETWB issued technical circular No.15/2003 requiring
contractors to prepare and implement a Waste Management Plan (WMP)
for all capital works projects tendered on or after 1 July 2003. Dedicated
payment is allocated under the contract for preparation and
implementation. This sets out the procedures for preparation and
implementation of an enhanced WMP to encourage on-site sorting of
Construction and Demolition (C&D) materials and to minimise their
generation during the course of construction. The requirements apply to
capital works contracts, including electrical and mechanical (E&M)
contracts and Design and Build (D&B) contracts but excluding term
contracts. C&D material means both inert and non-inert C&D materials.
Inert construction waste means waste that does not undergo any
significant physical, chemical or biological transformations. It will not
dissolve, burn or otherwise physically or chemically react, biodegrade or
adversely affect other matter with which it comes into contact in a way
likely to give rise to environmental pollution or harm human health. The
total leachability and pollutant content of the waste and the ecotoxicity of
the leachate must be insignificant, and in particular not endanger the
quality of surface water and/or groundwater. Soil, sand/aggregates,
bricks, concrete, cement and plaster are regarded as inert, whereas
general debris, plastics, paper, Styrofoam, timber, etc., are not.
On-site sorting of surplus construction and demolition (C&D) material is
desirable so that inert material can be disposed of at public filling areas,
and the remainder at landfills. Dumping Licenses require that material to
be disposed of at public filling areas must comprise only earth, building
debris, broken rock and concrete. Such materials shall be free from
marine mud, household refuse, plastic, metal, industrial and chemical
waste, animal and vegetable matter etc. The materials which are
considered unsuitable for disposal at public filling areas should go to a
landfill.
