PREFACE
Roads are an integral part of development, providing
people and businesses ease of access and movement.
The improvement of health, economy, and tourism all
depend on road networks. However, mere construction
of the infrastructure is not enough. Quality assurance,
which ensures that roads last according to their intended
lifespan, is equally as important, and serves as one of
the safeguards to ensure that resources are maximized
and not wasted. Simply put, safeguarding the quality of
the roads is good resources management. The local Road
Projects Quality Control & Quality Assurance Guidebook
was developed with this in mind.

INTRODUCTION & OVERVIEW
OF QUALITY ASSURANCE
ANDN QUALITY CONTROL
The DILG and DBM, in partnership with the Provincial LGUs (PLGUs),
are implementing the Conditional Matching Grant to Provinces (CMGP)
to improve the quality of local road network across the country, by
providing both financial investment for capital outlay, as well as
strengthening the governance processes so that provincial governments
are themselves able to effectively plan, design, implement and maintain
their road networks. The Program addresses the underinvestment in
local roads, and improvement of national-local roads connectivity to
increase economic activity and improve public access to facilities and
services in the provinces. With efficient, resilient and well-planned road
networks, no one is left behind in the goal of inclusive growth. Hence,
roads are fundamental for bringing communities together in order to
achieve the Sustainable Development Goals (SDGs).
complementary support.
UNDP launched the project “Paving the Roads to SDGs through Good
Local Governance (Roads2SDGs)”. The ‘Roads to SDGs’ Project aims
to provide support to the governance reform and quality assurance
components of CMGP through the ‘Roads to SDGs’ framework (Figure
1). The framework is anchored on two complementing principles –
The SDGs strongly influence and enhance road governance; and
good roads governance pave the way towards attaining the SDGs.
The ‘Roads to SDGs” framework will anchor the prioritization,
planning, design, implementation, and maintenance of infrastructure
projects to the achievement of the SDGs, incorporating the elements
of partnership building, climate change and disaster risk reduction,
gender mainstreaming, and citizen participation for transparency and
accountability. UNDP, the integrator to achieve the SDGs by 2030, will
be instrumental in fusing the SDG elements into the roads project.
I.2. OBJECTIVES
High quality workmanship is essential not only to get good value for
taxpayers’ money, but more importantly, to ensure the sustainability of
roads. Thus, it is important for LGUs and other government agencies
to implement road projects based on approved plans and design, and
to adhere to project standards and procedures. Of equal importance is
the need to establish a quality assurance structure that will monitor the
implementation of local road projects.
This section discusses the recommended QA structure and the divisions,
sections, units that should make up this structure. It also details the
duties and responsibilities of QA personnel and the responsibilities of
Contractors.
This section also defines some of the terms that will be used throughout
the guidebook.

I.8.1. Contractor
The LGU’s task is to verify that the Contractor’s quality control system
is functioning and the completed structure or part of the structure is of
the specified quality. The responsibility of the LGU’s representative is
confined to quality assurance checks or verification of Quality Control
Process.
The QA/QC program will usually be under the direction of the Materials
In-charge. The Materials In-Charge will be assisted by trained,
knowledgeable and experienced laboratory technicians capable of
documenting the operation and results of the QA/QC program. The

Figure 3 presents the five QA/QC procedures, which are carried out
during the Pre-Construction and Construction Phases, as follows:
1. PRE-CONSTRUCTION PHASE
The pre-construction phase serves as the foundation for the quality
control program. During this phase, project specifications are
determined, and the nature and amount of testing on materials are
also established. A dependable work program is also prepared in
order to ensure full compliance to project specifications as subsequent
inspection will be based on the standards and specifications that are
set during this phase.

QA and QC Procedures in Project Implementation 73
The Project Engineer shall have the authority to reject both unsatisfactory
workmanship and materials. Such rejections must be made immediately
upon discovery. This should be duly documented, with references
to the appropriate plans or specification requirement indicated.
Documentation should include photographs if possible. However, the
work shall not be directed to stop unless the non-conforming work shall
be covered up or the correction of the non-conforming work shall have
a critical impact on the completion of the project.
The Project Engineer will ensure that the inspection of the work is
organized to support the Contractor’s schedule. The Project Engineer
should also make sure that the inspection forces are available
and sufficient to meet the schedule. Every effort should be made to
cooperate with the Contractor so that inspection activities will dovetail
with the Contractor’s work. The inspection staff must be aware of the
daily and weekly schedules provided by the Contractor and schedule
their own work accordingly.

AASHTO Standards in
Materials Testing
Annex B: AASHTO Standards in Materials Testing 143
AASHTO T 24
This method covers obtaining, preparing, and testing (1) cores drilled
from concrete for length or compressive or splitting tensile strength
determinations; and (2) beams sawed from concrete for flexural
strength determinations.
AASHTO T 27
AASHTO T 88
The following applies to all specified limits in this standard: For the
purposes of determining conformance with these specifications, an
observed value or a calculated value shall be rounded off “to the
nearest unit” in the last right-hand place of figures used in expressing
the limiting value, in accordance with ASTM E29
Annex B: AASHTO Standards in Materials Testing 149
AASHTO T 89
The following applies to all specified limits in this standard: For the
purposes of determining conformance with these specifications, an
observed value or a calculated value shall be rounded off “to the
nearest unit” in the last right-hand place of figures used in expressing
the limiting value, in accordance with ASTM E29.
AASHTO T 90
The following applies to all specified limits in this standard: For the
purpose of determining conformance with these specifications, an
observed value or a calculated value shall be rounded off “to the
nearest unit” in the last right-hand place of figures used in expressing
the limiting value, in accordance with ASTM E29.
Two procedures for rolling out soil samples are provided in this
method: the Hand Rolling Method and the Plastic Limit Device
Method. The Hand Rolling Method shall be used as the referee
procedure.
AASHTO T 96
AASHTO T 180
This test method applies to soil mixtures that have 40 percent or less
retained on the 4.75-mm (No. 4) sieve, when Method A or B is used
and 30 percent or less retained on the 19.0-mm (0.75-in.) sieve, when
Method C or D is used. Material retained on these sieves shall be
defined as oversize particles (coarse particles).
AASHTO T 191
AASHTO T 193
Past practice has shown that CBR results for those materials having
substantial percentages of particles retained on the 4.75-mm (No. 4)
sieve are more variable than for finer materials. Consequently, more
trials may be required for these materials to establish a reliable CBR.
The agency requesting the test shall specify the water content or
range of water content and the dry unit mass for which the CBR is
desired.
AASHTO M 6
AASHTO M 80
AASHTO M 82
AASHTO M 85
Type I—For use when the special properties specified for any
other type are not required;
Type IA—Air-entraining cement for the same uses as
Type I, where air entrainment is desired;

In consonance with PD 1594 and its implementing rules and regulations as amended 13 April
1988, relative to the prequalification of contractors, and supplemental to Department Order
No. 36, series of 1987, regarding minimum equipment requirements, henceforth, the
evaluation of the contractor’s technical capability and financial capacity by the Prequalification,
Bids and Awards Committee shall include the minimum materials testing equipment to
effectively ensure the incorporation of the right quality of materials in the projects.
This minimum materials testing equipment requirement shall be on a “per contractor” basis,
and not on a “per project”, i.e., the equipment may be used to service several on-going projects
of the contractors.
Annexes 1, 2, and 3 present the list of the Minimum Materials Testing Equipment for Small,
Medium, and Large Contractors, respectively, as categorized under Department Order No.
41, series of 1987, which will form part of the evaluation of the Contractor’s capability.
As such, the list of major materials testing equipment in running condition owned by
Contractor, supported with proofs of ownership, shall be added under Item 2 (Equipment) of
the Technical Aspects, as indicated in the prescribed format for the Contractor’s Confidential
Prequalification Statement (Phase I).
