ISO 13315-6:2019(E)

Introduction
With their extremely long period of use and large size compared with other industrial products,
concrete structures undergo damage and deterioration during this period due to a variety of mechanical
and environmental actions. Maintenance/remedial activities are therefore carried out during this
period of use to maintain their functions and performances. Remedial activities can also be carried out
to enhance their functions and performances to adapt to changes in the social circumstances. These
activities cause environmental impacts, such as input of resources including repair materials and fuels,
greenhouse gas emissions including CO , and waste disposal including construction wastewater and
2
concrete rubble. Therefore, environmental management related to maintenance/remedial activities
during the period of use of concrete structures is necessary.
For a concrete building, the energy consumed during the period of its use is known to be greater than
the energy consumed for activities such as the production of raw materials, production/transportation
of concrete, and construction/demolition of the building. Energy consumption for air conditioning,
lighting, etc., and the concomitant emission of greenhouse gas are particularly enormous. Though the
ISO 13315 series does not directly cover energy efficiency of air conditioning and lighting equipment,
it covers the case where reduction in the environmental impacts, such as reduction of energy
consumption, is achieved by utilizing the properties of concrete. This include, for instance, mitigation
of room temperature changes by the thermal mass property of concrete. It also includes the use of
pervious concrete to suppress the heat island phenomenon, which reduces the energy consumption
for air conditioning, with the concomitant reduction in the emission of greenhouse gas. On the other
hand, hazardous substances can leach or radiate from concrete during the period of use of concrete
structures. Therefore, appropriate management of such various environmental influences generated
during the period of use of concrete structures is also necessary.

5 Principles and procedures for environmental management related to
maintenance/remedial activities of concrete structures
5.1 General
This clause provides the principles and procedures to appropriately carry out environmental
management for maintenance works and various construction works related to remedial activities.
NOTE See ISO 16311-1 regarding general principles of maintenance and remedial activities.
5.2 Maintenance of concrete structures
Since environmental impacts due to maintenance works are generally small, environmental
management can be simplified by either of the following methods:
a) for maintenance works that are repeated on a routine basis, carry out environmental management
by taking up a typical set of works and in consideration of the number of times and frequency;
b) for maintenance works that scarcely generate environmental impacts, exclude these works from
the subject of environmental management with clear documentation.
NOTE 1 Works that are repeated on a routine basis include, for instance, regular visual inspection by car.
NOTE 2 Works that scarcely generate environmental impacts include, for instance, routine looking-around
on foot.
5.3 Remedial activities for concrete structures
5.3.1 General
Environmental management of remedial activities shall be conducted appropriately in accordance with
the following procedure:
a) client briefing (see 5.3.2);
b) setting of environmental performance requirements (see 5.3.3);
c) design (see 5.3.4);
d) estimation (see 5.3.5);

5.3.4 Design
Remedial activities shall be designed to meet the environmental performance requirements set in 5.3.3.
Methods to ensure the required environmental performance include, for instance, the following:
a) selection of products, resources, and formwork/false work with low environmental impact (for
example, adopt alternative products/methods, optimize the transportation routes, etc.);
b) selection of energy sources with low environmental impact (for example, adopt renewable energy
sources);
c) selection of machinery/equipment with low environmental impact (for example, adopt hybrid
heavy machinery);
d) appropriate control/disposal of substances discharged on the site;
e) application of appropriate soundproof/vibration-proof measures (for example, install
soundproof walls).
NOTE See ISO 16311-3 regarding design of remedial activities.
5.3.5 Estimation
Each of the expected environmental performances of the remedial activity designed in 5.3.4 shall be
estimated.
5.3.6 Verification
Verification shall be made as to whether or not each of the expected environmental performances,
estimated in 5.3.5, meets the performance requirements set in 5.3.3. If any of the expected
environmental performances fails to meet the performance requirements, then re-design shall be
conducted by returning to 5.3.4. If the re-design fails to meet the requirements, the environmental
performance requirements shall be reviewed by returning to 5.3.3. If the re-design fails to meet the
reviewed environmental performance requirements, client briefing shall be carried out again by
returning to 5.3.2.
When it is impossible to formulate and execute environmental design that meets the environmental
performance requirements, the project can be cancelled.

5.3.7 Execution and related works
Construction works shall be carried out based on the design of the remedial activity, and necessary
data shall be acquired. Based on the acquired data, each of the attained environmental performances of
the remedial activity shall be confirmed.
NOTE See ISO 16311-4 regarding execution of remedial activities.
5.3.8 Inspection
Inspection shall be conducted as to whether or not the attained environmental performances meet
the environmental performance requirements. If the performances fail to meet the requirements, the
causes shall be analysed to contribute to the improvement of remedial activities in the future.
5.3.9 Documentation
All information related to the environmental management of remedial activities shall be recorded
regardless of the results of verification and inspection, and the record shall be stored by the designer of
remedial activities and the owner of the concrete structure for the required period.
Information related to the environmental management of remedial activities should preferably be used
to help the planning of similar projects.

6.2 Client briefing
A client brief shall be formulated regarding the environmental aspect related to the intended functions
of concrete and concrete structures during their operation, in consideration of the social and economic
aspects.
NOTE 1 The use of concrete and concrete structure has negative and beneficial environmental impacts during
their operation.
— Negative impacts include, for instance, emission of ammonia, radiation of radioactive radon contained in
aggregate, and leaching of heavy metals from underground concrete structures in an environment with a
constant stream of groundwater.
© ISO 2019 – All rights reserved 9

---------------------- Page: 14 ----------------------
ISO 13315-6:2019(E)

— Beneficial impacts include, for instance, reductions in the consumption of fuels for air conditioning and
emission of greenhouse gas by utilizing the thermal mass effect of concrete, water purification and suppression
of the heat island phenomenon by utilizing pervious concrete, and reduction in CO in the atmosphere due to
2
concrete carbonation.
NOTE 2 Annex B serves as a reference for methods of environmental consideration for concrete and concrete
structures in operation.

Appropriate indicators shall be set for each category selected.
The reduction amount of environmental impact or the reduction rate of environmental impact of the
target (concrete) structure in comparison with the reference (concrete) structure may be used as an
indicator.
