7.1. Construction Planning

7.1.1. Works Quality Plan (PQO)

Construction Company must, for each of their works,

elaborate a Works Quality Plan, according to others

Quality Management Systems requirements, which must

have some elements as follows, when appropriate:

i) definition on where the solid and liquid wastes will be

destinated (construction solid waste, sewage, used

water), which respects the environment.

This is ISO 9001:2008 specific for the civil construction industry

Solid Waste Management- 05/07/2002

(Complemented by CONAMA* Resolution no 348,

which includes asbestos products as D class -

dangerous)

*Brazilian National Environment Council


CDW classification proposed by CONAMA

307/2002 + CONAMA 348/2004 Resolutions

Class A: residues reusable or recyclable as

aggregates,

Class B: recyclable residues for other applications,

such as: plastics, paper/paper board, metals,

glasses and others;

Class C: residues for which no technologies or

economically feasible applications have been

developed which allow their recycling/recovery

(i.e.: gypsum).

Class D: dangerous residues, originated from the

construction process (paints, solvents, oils and

others) or those contaminated. Asbestos products.

Art. 13. Classification of Solid Waste, according

to this law:

I – Due to the origin:

h) Construction and Demolition Waste: residues

are those originated from constructions,

reformations, repairs and demolitions of civil

construction works and those resulting from the

preparation and excavation of lands, such as:

bricks, ceramic blocks, concrete;

Solid Waste State Plans

Art. 16. Developing the solid waste state plans, for this law, is the

condition for the States to have access to the government budget.

§ 3o Respeitada a responsabilidade dos geradores nos termos desta

Lei, as microrregiões instituídas conforme previsto no § 1o abrangem

atividades de coleta seletiva, recuperação e reciclagem, tratamento e

destinação final dos resíduos sólidos urbanos, civil construction

wastes management, de serviços de transporte, de serviços de

saúde, agrossilvopastoris ou outros resíduos, de acordo com as

peculiaridades microrregionais.

PGM CHARACTERISTICS

1st stage: Based on Clean Construction Waste

Program (Salvador- BA) – resulted on PEL –

adopted and launched in Goiânia on september

2002

2nd stage: resulted on Solid Waste Materials

Management Project (PGM) - Articulation with

the public power and the production sector for

the detailing and implantation of the Program.

Solid Waste Materials Management Project

Composed by a reduction plan, reusing and waste recycling - PmaisL;

Reduction must consider all phases and all participants of the waste generation process;

At reusing, materials that can be reused are identified and a reusing flow must be encouraged;

Recycling depends on the residue quality and appropriate segregation.

PILOT PROJECT 1 - OBJECTIVES

Construction sites CDW management– Cleaner

Production (PmaisL) and waste segregation

at the source;

Strengthening of the National Learning System

of the Construction Industry;

Public Power answering the obligations

established by the 307 CONAMA Resolution.

Practice:

Implementing the CDW reusing process;

Implementing the CDW management projects;

The flowing off of segregated wastes;

Encourage the development of researches to produce

new materials and compounds using recycled

aggregates.


PILOT PROJECT 1 - IMPLANTATION STEPS

IMPLANTATION STEPS

Definition of local strategic group and project presentation;

Development and implementation of Construction Solid Waste Materials Management Project;

Designation of area to receive those segregate waste at construction sites;

Residues characterization and analyses (FURNAS);

Residues processing (Goiânia Municipality);

Recycled aggregates utilization (FURNAS and Federal University of Goiás).

First stage results: Clean Construction waste

Program (PEL).

Results related to the Materials Management

Program (PGM):

General results of PGM,

Results related to the institutions which

participates of the program point of view.

PEL RESULTS

Changing behaviour and values: more critical

behaviour and sustainable of their

operacional processes;

Civil construction solid waste segregation,

turning viable new environmental and social

sustainables practicals;

Adequation to the legal legislation CONAMA

307 resolution.

Guidebook – Clean Waste Program

PGM RESULTS OF STAGE 1-

GOIÂNIA

Guidebook front page: PGM Construction site Management Project

Results at the construction sites

Organization and cleanness of the

construction sites

Cleaner constructions

Operational people more educated

Reduction of number of containers – about

40 to 50%

Results for the environment

Reduction of about 60% to 80% of solid waste

from construction and demolition going to landfills

and illegally at the environment;

Possibility of soil and underground water pollution

reduction, with the reduction of wastes irregularly

disposal;

Possibility reduction of urban drainage impacts,

with the irregularly disposal reduction;

Possibility reduction of vectors of diseases wich

are concentrated in residues irregularly disposal.

Results for the environment

FINAL REMARKS

Engineering challenge to this century is

to live in harmony with the environment

and the sustainable development is the

way to get this goal (MEHTA, 1999).
