sites.
CREDITS ATTAINABLE 1 BONUS
PREREQUISITES None.
CREDIT REQUIREMENT 1 BONUS credit for conducting a site contamination assessment and
implementing measures for rehabilitation, and/or proper preparation of

ASSESSMENT a) Contaminated sites
The Client shall submit evidence in the form of a report prepared by a
suitably qualified person that demonstrates through a site contamination
assessment that the issues and requirements outlined in Guidance Note
for Contaminated Land Assessment and Remediation [1] have been
addressed and that the immediate environment are free from any
hazardous contamination. The report shall confirm that the required
remedial measures, other than excavation and transfer to landfill (which
is not regarded as an environmentally sound solution), have been
completed to restore the land to an acceptable condition for use for the
building redevelopment.
b) Sites adjacent to landfill
The Client shall provide evidence in the form of a report prepared by a
suitably qualified person confirming that the site has been properly
assessed and all issues and requirements outlined in ProPECC PN 3/96
[2] have been adequately addressed. Due consideration to gas hazards
that may arise during the construction, phase shall be included.
BACKGROUND Derelict land and sites previously used as factories, shipyards, for
chemical manufacturing or processing, oil deports, car repair workshops,
waste treatment, etc., might be contaminated by hazardous substances
such as oil, heavy metals and organic substances. Most of these sites
are targeted for renewal in the Urban Renewal Strategy Study. Such land
can pose risks to users, the adjacent environment or even the building
materials, possibly undermining the integrity of the building. Special
attention and rehabilitation may be required. Reclaimed land constructed
with soil dredged from seabed or construction and demolition material
can also be contaminated.
Guidance Note for Contaminated Land Assessment and Remediation
sets out requirements for proper assessment and management of
potentially contaminated sites, and suggests practical remedial
measures that can be adopted for the clean-up of a contaminated site.
Although the requirements set out in the Guidance Note are usually
incorporated through the land use planning process, either as conditions
