Material Testing and Documentation
A.
Scope of Work
Material Testing
Seven (7) days upon receipt of the Notice to Proceed (NTP), The Contractor or his duly authorized
materials engineer together with the Materials Engineer of SBMA shall jointly undertake sampling and
testing of all material requirements of the Contract for the purposes of this project. The Materials Engineer of
SBMA must see to it that extra samples be set aside in his/her office for future reference purposes. It shall be
the responsibility of the Contractor’s Materials Engineer to ensure the integrity of the materials for testing.
All tests shall be normally carried out on the site, except that certain special tests may, subject to the approval
of the Materials Engineer for SBMA, be carried out at an independent testing laboratory duly approved and
accredited by the Department of Public Works and Highways (DPWH). The Contractor shall, if so approved,
make all necessary arrangements for the supply and delivery of samples to, and collection of samples from
such independent Laboratory. Unless otherwise specified, the Contractor shall arrange for one (1) copy of the
independent testing laboratory test certificate to be delivered to the Materials Engineer for SBMA not less than
three (3) days before the materials covered by the relevant test certificate are incorporated in the Works, and
test certificates shall be relatable to the materials from which the sample was taken.
Accredited Testing Laboratory
Testing of materials shall be carried out, conducted or be performed at testing laboratory accredited by the
Bureau of Research and Standard (BRS) of the Department of Public Works and Highways (DPWH) and
Department of Science and Technology (DOST).
Minimum Testing Requirements (MTR)
The Minimum Testing Requirements (MTR) is prepared to specify the type and frequency of tests to be
undertaken for materials and products contained in the DPWH Standard Specifications as enforced through the
latest DPWH Department Order (D.O. No. 49 Series 2021) governing minimum testing requirements of item of
7
work. The implementation of the MTR shall strengthen the Quality Control of the Contractors and the Quality
Assurance Program of the Department
The MTR is issued together with the list of Quality Tests (Annex A) and list of Standard Test Methods (Annex B).
Refer to the latest DPWH Schedule of Minimum Testing Requirements Governing Items of Work of the DPWH
Standard Specifications for Public Works Structures (Buildings, Ports and Harbors, Flood Control and Drainage
Structures and Water Supply Systems), Volume III, 2019 Edition. In Annex A, the required Quality Tests in the
MTR are specified per material. On the other hand, Standard Test Methods and reference Standard
Specifications such as the American Society for Testing and Materials (ASTM), American Association of State
Highway and Transportation Officials (AASHTO), International Organization for Standardization (ISO), and
Philippine National Standards (PNS) are enumerated in Annex B. The listed reference standards’
designation/code comprises its year/edition in which the values, specification or requirements are being used
or referred from. Nevertheless, some standards will follow the latest year/edition when the Annexes are being
prepared.
For easy reference purposes, materials in the MTR are presented per Item of Work. Composite materials are
broken down into its basic components whenever separate/individual testing is applicable or required. Some
materials are also repeatedly presented per Item where it is used for quick reference.
In as much as new and improved testing methods and specifications are constantly being developed, it is
contemplated that MTR will be revised from time to time.
Further, existing issuances relative to Quality Control and Quality Assurance shall continue to be enforced.
Guidelines for the Implementation of MTR
1.
Quality Tests
Quality Tests includes the chemical and/or physical tests required to be conducted on a material or product in
accordance with the DPWH Standard Specifications. Quality tests are listed down in Annex A - Quality Tests on
Construction Materials, with its corresponding Standard Test Method shown in Annex B – Reference Standards.
All quality tests are required to be satisfied. Tests shall be done based on the Frequency specified in the MTR.
Where, the number of times the required tests must be done relative to the quantity specified in the MTR per
size, type, layer, batch, lot, shipment or source.
For cases where not all the required tests in quality test list can be performed, the Original Mill Certificate
(OMC) will serve as supplemental document.
2.
Original Mill Certificate (OMC)
OMC is a quality assurance document generated by the raw material manufacturer and provided with the
material to intermediate suppliers and ultimately to a finished goods manufacturer. It certifies the
materials’ compliance with the standard specification such as ASTM, AASHTO, PNS, ACI, etc.
The OMC per batch production must be supplied by the Supplier/Contractor. For cases where original
product Authentication Certificate (Red Ribbon) is not possible to obtain, supplier may opt to provide an
Authentication Certificate issued by the Department of Foreign Affairs (DFA). For multiple copies of such
document, a Certified True Copy will also be accepted.
OMC is a supplemental document for materials where not all of its required tests can be satisfied or
performed, such as those pertaining to third-party testing of elevators or lifts (see succeeding page).
3.
Other Than Test
These are additional requirements that must be submitted/produced/accomplished by the Contractor as
part of its Quality Control measure such as Welding Report, Inspection Report of Casting, Geotechnical
Investigation Report, or Concrete Monitoring Record. The attached standard format for these documents
should be strictly complied.
8
4.
Engineer’s Certificate (EC)
EC is part of DPWH’s Quality Assurance and shall be issued provided that the specifications of the
material/product satisfied/passed the requirements stipulated in the DPWH Standard Specifications.
It is also an additional requirement if the implementing office of SBMA or the third party has no capability
to perform such test. The EC shall be prepared by the SBMA Materials Engineer or Consultant’s Materials
Engineer in a standard format approved by the implementing office of SBMA. When signed “as received”
by the SBMA Project Engineer or Consultant’s Resident Engineer and SBMA Materials Engineer or
Consultant’s Quality Assurance Engineer, EC is a QA/QC record.
If in doubt, the Procuring Entity, or its authorized representative from the implementing office/
department, may have the option to conduct tests prior to issuance of the EC.
Definition of Terms
Test Required – Mandatory tests to be done on the materials prior to its incorporation/use in the
implementation of Item of Work.
