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.

Class A: residues reusable or recyclable as
aggregates,
Class B: recyclable residues for other applications,

glasses and others;
Class C: residues for which no technologies or
economically feasible applications have been
developed which allow their recycling/recovery

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
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
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.
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

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.
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).
