Introduction
Execution of a concrete structure refers to activities of constructing a relatively large-scale structure as
single production at a given construction site. It essentially differs from ordinary industrial products, which,
as a result of mass production, have similar functions and performances to each other. When executing a
concrete structure, it is necessary to plan and execute each phase of construction work in consideration
of the scale of execution, condition of the ground, procurement conditions for materials and equipment,
ambient environment and global environment.
Execution of a concrete structure generally includes earthwork and foundation work, formwork,
reinforcement work and concreting work.
Such construction works cause a wide variety of environmental impacts. These include, for instance,
consumption of resources by the input of materials to execution of concrete structures; consumption of fuels
and electric power by the transportation of materials, equipment and heavy machinery and operation of
equipment and heavy machinery; and discharge of global warming substances and air-polluting substances
while generating noise and vibration. Earthwork and foundation work generate solid waste including
excavated soil, rock, dug-out roots, sludge and mud, dust and wastewater. Formwork generates used forms,
and reinforcement work generates metal waste. Concreting work generates washwater for concrete pumps
and buckets and concrete waste.
It is therefore necessary to appropriately manage the environmental impacts generated by execution of
concrete structures.

5 Principles and procedure for environmental management related to execution of
concrete structures
5.1 Principles
In the execution of a concrete structure, environmental management shall be carried out for the entire
work consisting of earthwork/foundation work, formwork, reinforcement work, concreting work and waste
treatment, or each of these works or combinations thereof.

5.2 Procedure
Environmental management of execution activity shall be carried out in accordance with the following
procedure:
a) confirmation of the client brief and design documents and specifications (see 5.3);
b) setting of the environmental performance requirements (see 5.4);
c) formulation of the construction plan (see 5.5);
d) estimation (see 5.6);
e) verification (see 5.7);
f) execution of construction and related works (see 5.8);
g) inspection (see 5.9);
h) documentation (see 5.10).
Figure 1 shows the flow chart of this procedure.

Figure 1 — Procedure for environmental management of execution activity
5.3 Confirmation of the client brief and design documents and specifications
The client brief at the design stage and design documents and specifications shall be confirmed. When the
structure is found not to incorporate environmental design based on ISO 13315-4 at the design stage, a client
briefing regarding the environmental aspect of the execution activity shall be carried out in consideration of

the social and economic aspects, and the results shall be reflected in the specifications for execution through
an appropriate procedure.
5.4 Setting of the environmental performance requirements
5.4.1 Selection of impact categories
Impact categories shall be selected from among the following items based on the client brief and design
documents and specifications:
— global climate change;
— natural resources use;
— stratospheric ozone level;
— land use/habitat alteration;
— eutrophication;
— acidification;
— air pollution;
— water pollution;
— soil contamination;
— pollution due to radioactive substances;
— impacts due to waste generation;
— noise/vibration.
NOTE ISO 14040 and ISO 14044 serve as references for selecting impact categories.
5.4.2 Setting of indicators
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
execution activity in comparison with the reference execution activity can be used as an indicator. The
environmental performance of the reference execution activity shall be appropriately estimated.
NOTE 1 ISO 21929-1, ISO/TS 21929-2, ISO 21931-1 and Annex A serve as a reference for setting indicators.
NOTE 2 To assess whether a product is environmentally labelled, Boolean indicator is a useful option to be set.
5.4.3 Setting of environmental performance requirements for indicators
An environmental performance requirement shall be set for each indicator in each impact category.
The environmental performance requirements shall be quantitatively set in the form of upper limits, lower
limits, or ranges of the indicators.
NOTE 1 The reduction amount of environmental impact of the target execution activity, Ri() , refers to the
Atexe
difference between the environmental performance of the reference execution activity and the expected or attained
environmental performance of the target execution activity. It is defined as Formula (1).
Ri()Pi() Pi() (1)

The reduction rate of environmental impact of the target execution activity, Ri() , refers to the ratio of the
Rtexe
reduction of the environmental impact, Ri() , to the environmental performance of the reference execution
Atexe
activity. It is defined as Formula (2).

NOTE 2 ISO 14040 and ISO 14044 serve as references for setting of environmental performance requirements.
5.5 Formulation of the construction plan
The entire work subject to environmental management or respective works or combinations thereof shall
be selected from among items a) to e) below:
a) earthwork and foundation work;
b) formwork;
c) reinforcement work;
d) concreting work;
e) waste treatment.
A construction plan shall be formulated by determining the methods of reducing environmental impacts
to be applied to the work selected above to satisfy the environmental performance requirements set in 5.4.
Such methods include the following:
— selection of products and resources with low environmental impacts, for example to select environmental
labelled products;
— selection of energy sources with low environmental impacts;
— selection of machinery/equipment with low environmental impacts;
— selection of execution methods or procedures with low environmental impacts;
— appropriate control/disposal of substances discharged from the site;
— appropriate control/disposal of substances treated within the site.
NOTE 1 Annex B serves as a reference for methods of reducing environmental impacts.
NOTE 2 ISO 13315-8 serves as references for selecting products with environmental labelling and declaration.
5.6 Estimation
Each of the expected environmental performances of the execution activity based on construction plan
formulated in 5.5 shall be estimated.
5.7 Verification
Verification shall be made as to whether each of the expected environmental performances, estimated in
5.6, meets the environmental performance requirements set in 5.4. If any of the expected environmental
performances fail to meet the environmental performance requirements, then the construction plan shall be
modified by returning to 5.5. If the requirements are not satisfied by this modification, the environmental
performance requirements shall be reviewed by returning to 5.4. If the construction plan fails to meet the
reviewed environmental performance requirements, a client briefing shall be held on the environmental
aspects of the construction by returning to 5.3, and, if necessary, the specifications for the execution shall be
modified based on agreement among the parties concerned.

5.8 Execution of construction and related works
Construction works shall be executed based on the construction plan and necessary data shall be acquired.
Based on the acquired data, each of the attained environmental performances shall be confirmed.
5.9 Inspection
Inspection shall be conducted as to whether the attained environmental performances meet the
environmental performance requirements. If performances fail to meet the requirements, the causes shall
be analysed to serve as a reference for execution activities in future projects.
5.10 Documentation
All information related to environmental management of the execution of the concrete structure shall
be recorded regardless of the results of verification and inspection, and the record shall be stored by the
designer, contractor and owner of the concrete structure for the required period.
Information related to environmental management of execution of the concrete structure should preferably
be used to help the execution planning of similar concrete structures.
