The reduction of C&D waste continues to be a key concern of the Department. The requirements for "waste management plan” and the implementation of the trip-ticket system are specified in the contract documents and site works are closely monitored by our supervisory staff. In the design stage, we specify the use of system formwork, steel formwork and prefabrication to minimise C&D waste generation.	Cover is provided to dump truck before leaving the site, after checking of trip ticket
Through the trip-ticket system, in which C&D waste cannot be dumped at designated fill sites without proper record, it enables better monitoring against illegal dumping. The outcome: Zero cases of unauthorised dumping involving our Department's projects in 2004, compared to two cases reported in 2003.	Waste paper is collected and delivered to recycler
	Systematic sorting for re-use or recycling of construction materials

Environmental Assessment of Buildings

We promote holistic environmental design and conduct environmental assessment of our buildings to ensure we adhere to recognised standards. One of the tools we used is the scheme by the Hong Kong Building Environmental Assessment Method (HK-BEAM) which promotes environmentally friendly design, construction and management for buildings.

In 2004, ten of our projects were assessed. Eight were given an "Excellent” rating, the highest available, and two were given a "Very Good” rating. Our buildings rated "Excellent” are listed below.

Environmental Awareness Promotion

We engage with our working partners, other government departments and the general public to raise their environmental awareness. Our activities in 2004 include:

• Experience sharing - Two government seminars on "Mosquito Control on Construction Sites” and "Managing Site Safety & Environmental Protection” attended by 570 people; and a presentation at the Hong Kong Institution of Engineers Seminar on "Enhancement of Housekeeping in Building Sites”
• Preparation and completion of 20 papers in 2004 for local, regional and international events related to sustainable development. A selected list is in the table below.

Resources for Environmental Protection

A considerable portion of our project expenditure is devoted to environmental protection. For environmental accounting purposes, we define work in the following areas as environmental costs: Air and water pollution control, noise mitigation measures, waste water treatment and disposal, asbestos abatement works, environmental review and impact assessment for projects, resources spent for environment-related works, maintenance of environmental management system in accordance with ISO14001 and housekeeping activities. We strive to provide the public with a sustainable built environment and will continue to invest steadily in environmentally sound solutions for our projects.
