Study Notes
Course Goals and Importance
- Course aims to train students in standard testing procedures for common construction materials.
- Prepares students for the DPWH-BRS Materials Engineering examination, crucial for civil engineers in construction.
- Emphasizes testing materials (cement, sand, gravel, concrete, masonry, steel, wood) to assess physical and mechanical properties.
- Highlights importance of material testing to identify potential construction issues and ensure safety.
Construction Classifications in the Philippines
- Reinforced Concrete: Most commonly used due to cost-effectiveness; combines concrete with steel reinforcing bars.
- Structural Steel: Preferred for large warehouses and factories; includes hot-rolled steel like I beams and C Channels.
- Masonry: Typically used for bungalows; vulnerable to lateral forces, often considered non-engineered.
- Wood: Cost varies by type; safer against earthquakes but weaker in high winds; requires pre-use testing.
Standards and Specifications
- Materials testing is regulated by ASTM standards, widely adopted in the Philippines, with over 12,800 standards available in English and SI units.
- DPWH-BRS provides standard specifications for construction materials in public works projects.
- Usage of sub-standard materials is legally punishable.
Testing Standards and Methods
- Relevant ASTM standards include procedures for determining particle size, moisture content, and density for aggregates.
- Other key tests assess compressive strength of concrete and masonry specimens, ensuring material integrity and performance.
Safety and Laboratory Protocols
- Prioritizes safety; unnecessary tasks in the lab are prohibited, and proper equipment handling is mandated.
- First aid kits are available, and lab supervision is required when operating specific equipment like UTM and ovens.
- Cleanliness is essential; all equipment must be cleaned after use.
Accreditation and Examination for Materials Engineers
- Minimum requirement for accreditation: must be a registered and licensed Civil Engineer.
- Written examination grading converts raw scores to a percentage; Practical examinations assess real-world testing capabilities.
- Limits on assignments based on engineer classification (I or II) ensure manageable project oversight.
Project Assignment Limits for Engineers
- Materials Engineer I: Can oversee one project ≤ P150M, two projects ≤ P250M, or three projects ≤ P200M.
- Materials Engineer II: Can manage one project without cost limit or two projects ≤ P300M, or three projects ≤ P250M.
Key Regulations and Updates
- Department Order No. 098 Series of 2016 mandates adherence to DPWH specifications for all relevant infrastructure projects.
- DPWH guidelines prevent government engineers from engaging as private consultants while employed.
Conclusion
- Knowledge of testing standards, materials classifications, safety protocols, and accreditation criteria is vital for aspiring civil engineers in the construction industry.
