Module 1 Introduction Note: All Standards, Equipment, Apparatus cited on this presentation conforms to the ASTM Standards and Specifications.  The GOAL of this course is to familiarize and train the students in the standard testing procedures of common construction materials For students to be ready for the DPWH-BRS Materials Engineering examination, which is an essential advantage of a Professional Civil Engineer working in the construction industry. To prepare students for Researches related to material testing especially concrete engineering.  It is essential to test all the materials such as (cement, sand, gravel, concrete, masonry, steel and wood) in order to determine its physical and mechanical properties. Construction in the Philippines is usually classified by these techniques/materials: 1. Reinforced Concrete 2. Structural Steel 3. Masonry 4. Wood/Bamboo  Reinforced Concrete is the typical material, technique used for building in the Philippines because of its lower cost compared to other materials. Made from concrete and steel reinforcing bars.

Structural Steel (I beams and C Channel) are made from hot rolled steel.

Wood shall be tested first before using as the main structural system. Source: https://bluprint.onemega.com 1. Testing of materials will identify potential problems during and after the construction of the project. 2. Ensures the safety of the structure and its occupants. 3. Usage and selling of sub-standard construction materials is punishable by law.  Name of Material BPS DESIGNATION NO.

The bureau of Research and Standard is the governing body that strictly follow the standards of construction materials  ASTM is the leading organization that standardized the testing of materials specially for construction materials. The Philippines is following most of the methodologies and techniques based on their procedures.

Handling of certain equipment will be discussed on the following presentations. 1. Safety is top priority of our school. All unnecessary task/behavior is prohibited on the laboratory. 2. Turn off all equipment specially electronic devices/heat related equipment after usage. 3. First aid kits are all available in the laboratory. 4. Call for help if needed. 5. Do not operate UTM and oven without the supervision of the faculty member or laboratory assistant. 6. No eating allowed in the laboratory 7. Immediately clean all equipment and tools after usage.  ASTM is the leading organization for standardizing materials and its testing 12,800+ Standards 110 Countries Adopted their standards Available in English and SI Units 100 Barr Harbor Drive P.O.

Member will identify certain problem, material, revision of existing standard 2. Members will prepare a draft standard 3. The parent subcommittee will review the proposed standard. It is hereby directed that henceforth, the DPWH Standard Specifications for Public Works and Highways 2004 Edition: Volume II – Highways, Bridges and Airports shall be adopted in the implementation of all infrastructure projects of said categories; except for projects which have already been advertised for bids and for which specifications other than the above standards have been adopted. Where necessary, these Standard Specifications shall be supplemented by special provisions. Department Order No. 098 Series of 2016 1.0 CRITERIA FOR ACCREDITATION The following criteria shall be applied in the evaluation for accreditation of Contractors’/Consultants’ Materials Engineers: 1.1 Minimum Requirement As a minimum requirement for accreditation of materials engineers, the applicant must be a registered and licensed Civil Engineer. This minimum requirement may be extended to foreign applicants. 1.2 Written Examination A written examination shall be administered to all the applicants. The raw score obtained in the examination shall be converted to percentage (100% maximum) to obtain the total score for accreditation. 1.0 CRITERIA FOR ACCREDITATION 1.3 Practical Examination Practical examination shall be administered to an accredited Materials Engineer I applying for upgrading to Materials Engineer II. It shall be conducted at the Bureau of Research and Standards (BRS) Office in Quezon City or at a selectedjidentified DPWH Regional Office. 1.4 DPWH Engineers and other government engineers are prohibited from taking the examination for the accreditation of Contractors’jConsultants Materials Engineers to prevent private entities from engaging the servicesof the former while still employed by the government. 4.0 CLASSIFICATION OF CONTRACTORS’/CONSULTANTS’ MATERIALS ENGINEERS 4.1 Materials Engineers shall be classified according to the results of Written and Practical Examinations. 4.1.1 Written Examination Applicants who got a score of 60% and above are automatically accredited as Materials Engineer I. 4.1.2 Practical Examinations (For upgrading from Materials Engineer I to Materials II only) a. Laboratory The applicants will be required to demonstrate the actual sampling and testing procedures of construction materials in accordance with the existing standards to determine their testing capability. b. Field The applicants will be required to demonstrate the actual implementation of quality control supervision and decision making in the project. 4.2 Accredited Materials Engineer I may be upgraded to Materials Engineer II by undergoing only a Practical Examination and not a written examination. Applicants must obtain a total score of at least 75% in the Practical Examination to qualify as Materials Engineer II. 4.3 Accredited Materials Engineer I who applied for upgrading but failed to be upgraded to Materials Engineer II after two (2) successive attempts is barred from taking the Practical Examination for one (1) year and should take a refresher course related to Materials Quality Control. 4.4 An accredited Contractors’/Consultants’ Materials Engineer who enters the government service and wishes to be accredited as DPWH Materials Engineer may apply for accreditation. His/her score in the written examination will be considered and he/she must undergo the practical examination. However, in the case of upgraded Materials Engineer II who have undergone practical examination, he/she will be automatically conferred the same rank. 4.5 DPWH engineers who took the DPWH Materials Engineers examination and got a score of 60% and above but are separated from government service can be accredited as Contractors’/Consultants’ Materials Engineers I, without undergoing practical examination for Contractors’/Consultants’ Materials Engineers. 5.0 CRITERIA FOR THE ASSIGNMENT OF CONTRACTORS’ / CONSULTANTS’ MATERIALS ENGINEERS Accredited materials engineers may be assigned to DPWH projects, subject to the following limits of assignment: Classification Limits of Assignment a. Materials Engineer I – One (1) project costing not more than P150M, or – Two (2) projects, with an aggregate cost of not more than P250M, or – Three (3) projects, with an aggregate cost of not more than P200M. 5.0 CRITERIA FOR THE ASSIGNMENT OF CONTRACTORS’ / CONSULTANTS’ MATERIALS ENGINEERS Accredited materials engineers may be assigned to DPWH projects, subject to the following limits of assignment: Classification Limits of Assignment b. Materials Engineer II – One (1) project, no cost limit, or – Two (2) projects, with an aggregate cost of not more than P300M, or – Three (3) projects, with an aggregate cost of not more than P250M. Non-accredited materials engineers may be assigned to three (3) projects, with an aggregate cost of P150M or below ASTM stands for? Why is Reinforced Concrete the choice material for most of the construction in the Philippines?  END OF PRESENTATION THANKS FOR LISTENING!
