SECTION 5:
THE SUSTAINABLE CONSTRUCTION
OF BUILDINGS
199
If the full benefits of sustainable site selection and building design are to be
realised, the construction phase must also be planned and conducted with
environment consideration.
In the run-up to the construction phase, it is common practice for some design and
material specifications to be revised and alternatives considered. Care must be
taken to ensure that the chosen alternatives do not impair the sustainable design
features, reduce the energy and material efficiency of the building, or compromise
on the use of environment-friendly building materials.
The environment integrity of the site must be preserved at all costs. Bulldozing is
to be avoided, vegetation cleared only where buildings are to be erected.
The recommendations of the EIA should provide valuable guidance throughout
construction, especially in identifying vegetation that needs to be protected,
reducing waste and emissions, the use of prevailing vegetation in landscaping,
and preventing the erosion of topsoil and the silting of nearby waterways.

Sustainable construction is also about making the construction site a cleaner and
safer workplace:
• Separate areas should be provided for the storage of hazardous and
toxic materials;
• Recycling collection points for construction debris, food waste and
packaging waste need to be set up;
• Safety equipment and protective clothing should be provided;
• Safety standards on the use of construction equipment and exposure to
toxic materials should never be compromised;
• Procedures and safety measures in the case of fire, spills and accidents
should be clearly understood and respected.
These criteria also apply to the refurbishment of existing buildings.
